The Vaccination Controversy, Part 1 of 3

Lately I have been getting a lot of questions from clients in my practice about vaccinations. This is a controversial topic about which there are mostly extreme and contradictory points of view. As always, I will do my best to approach it in a balanced way and will likely upset people on both ends of the spectrum. I even risk ridicule by calling it a "controversy" because most people's perspective on this issue is so extreme that they simply believe that they are right, it's obvious, and anyone who disagrees is ignorant. For example, with the recent outbreaks of measles in several North American cities there has been media blitz aimed at demonizing anyone who opposes vaccinations. Even supposedly "liberal" media such as the CBC have jumped on this bandwagon.

As I'm sure is apparent from my other blog posts, I try to be as thorough as possible. However, this is a very complex topic and it would take a whole book or possibly even several books to fully explore it. I am going to do my best to look at vaccinations in as holistic a way as possible and to provide as much information as I can within the limitations of this format. As a result, it will be necessary to cover the subject in three posts. In this first post I am going to lay out the broader issues. In Part 2 I will look at some of the pros and cons of vaccinating and introduce a couple of good resources where you can get more information, and in Part 3 I'm going to present some basic protocols that can help boost immune function and reduce the incidence and severity of infectious conditions and the potential side-effects of vaccinations. The recommendations that I will provide will be useful for anyone regardless of the choices they make regarding vaccinations.

What I am not going to be able to do is to make your decision for you. Unfortunately, there is not a lot of good information out there and there are many more questions than answers. The kind of studies that need to be done to more clearly demonstrate the health consequences of vaccinating—both positive and negative—are not being done and probably no longer can be done. The best we can do is educate ourselves; approach the information that is available with an open mind; recognize that, no matter how rational it sounds, a lot of that information is coming from extreme positions; and then make the best decision that we can. It is best if our decision is as informed as possible, but ultimately we'll need to make it with our heart because there simply is not enough good information available to know with certainty what the "right" decision is. We have to accept that, no matter what decision we make, some of our kids are going to get sick and a few of them very sick. When that happens, although there are going to be many people out there who will point their fingers and use the less fortunate as statistics to "prove" their point of view, the truth is that we will never know if things would have been different had we made a different decision. All we can do is our best.

The last thing I should point out before getting into this topic is that I live in Canada and have the benefit of living in a privileged society. My experience is coloured by living in one of the more affluent "First World" nations. I can not speak with the same level of confidence about poorer countries where proper sanitation, clean water and decent nutrition are not available to a significant proportion of the population. The discussion of infectious disease and vaccinations is different in those parts of the world. The information that I will be presenting is still relevant in those countries, but the priorities and available resources are different.

To vaccinate or not to vaccinate? That is the question!

When it comes to vaccinations, people tend to fall into one of three camps: the mainstream medical-industrial complex and those who completely buy into their medical dogma; those who distrust mainstream medicine and think that vaccinations are the cause of much of what ails us; and those who are confused by all of the contradictory information and are trying to make their way through the rhetoric. I am mostly speaking to people in the last group because most of the proponents of the other two points of view have already made up their minds and no amount of reasonable discourse is going to change it. However, I hope that these posts will also be helpful to some of the advocates and opponents of vaccinations whose views are a little less extreme.

In approaching this topic, one of the important things to keep in mind is that regardless of where everyone falls on the spectrum of opinions, they all want the same thing: to protect the health of their families, themselves, and their society. Unfortunately, with emotionally charged issues such as this, it is almost impossible to be objective because people's perspectives are mostly based on fear: fear of microbes; fear of disease; fear of people with a different point of view; fear of being wrong; fear of what we can't control; fear of the unknown. This is an unfortunate characteristic of human nature—at least how we've cultivated human nature in the modern world. Even the self-proclaimed rational, scientific types can't see that their rationality rests on a foundation of fear. It's a big, beautiful, mysterious world that we live in! A world in which what we experience as suffering, disease and death are an integral part. We will never be able to understand or control more than the tiniest fraction of the world, and even then our "understanding" and "control" are largely an illusion. The World and Nature have their way and we are part of it. It's better to embrace the mystery and learn to flow with the world rather than attempt to mold it to our ideas about how it should be. We do that at our own peril—the consequences of which are all around us.

OK, enough philosophy! In approaching this issue, it is important to remember that we do have options: we can choose to follow the directions of our doctor; we can choose an alternative vaccination protocol getting only some of them and/or changing the timing of them; and we can choose to avoid them altogether. The degree to which we can exercise these options depends on where we live. It is important to find out what the options are in your local jurisdiction. It is also important to keep in mind that sometimes people in authority will lie to you. They will tell you that you don't have options when you really do. Sometimes it may be because they just don't know. If few or none of the other parents in a school have made alternative choices, the situation may not have come up for the person you are dealing with. However, more often than not they are trying to manipulate you. Once more it's important to realize that they are doing it out of fear and because they believe it is the right decision. It is not out of malicious intent.

Another thing you might come across are doctors who are unwilling to alter the vaccination protocol or who might not even be willing to treat your children if they aren't fully vaccinated. All of these factors affect our options. If we feel strongly about our choices it might necessitate changing our doctor, daycare, school, or even moving to a different city, province or state. All of these things need to be considered.

So lets start at the beginning...

Every region has its particular ecosystem based on the features of the landscape, soil, climate, and all of the various organisms that live there. There is an ebb and flow and, contrary to the "survival of the fittest" model of ecology, although competition is a component, to a larger extent ecology is about cooperation between species. Yes, individuals die and sometimes entire species disappear, but life is really not about individuals. The ecosystem is a living organism and the relationship between species like us to the whole is more like the relationship of bacteria on our skin to our body as a whole. We are just one of many species integrated into the the world in which we live.

Life in balance!

What we think of as "disease" organisms are also important parts of the ecology. Among other things, they help to maintain balance by providing healthy immune stress for individual organisms, weeding out the weaker members of a species, and keeping populations in check. I am sure that they have many other roles that we don't understand, but these are their most important known functions for the purposes of this discussion.

Outbreaks of illnesses associated with particular microorganisms come and go in accordance with natural cycles. For the most part, as long as a particular species and the local ecosystem as a whole are in balance, these outbreaks are not too destructive. However, if a species is out of balance they can be devastating. Similarly, when an organism that isn't a natural part of the local ecology is introduced the results can potentially be catastrophic. For example, it is estimated that the introduction of European diseases resulted in the death of 60-80% of the population of First Nations peoples in North America. Such tragedy is beyond comprehension. On a different level, Dutch elm disease devastated the native elm populations in North America when the fungus that causes it and at least one species of beetle that spreads it were introduced from Europe. In both of these situations it is important to keep in mind that the arrival of Europeans in North America disturbed the balance of the local ecosystem and the social structure of First Nations peoples in many ways. The introduction of novel species is just one of them.

Viruses are people too—and they're cute!

Most of the vaccinations that are part of public vaccination programs are for cyclic illnesses that were once common. When I was a kid in the 60s, illnesses such as measles, chicken pox and mumps cycled through on a regular basis. When they did, adults rarely got them because they had a natural immunity having been exposed as children. Among the children who were exposed, many of them were asymptomatic. This means that their immune system was strong enough to bring the infection under control before any symptoms developed. The kids that did develop symptoms experienced symptoms of varying degrees of severity, with most being mild to moderate and very few being severe enough to be considered serious. The relative severity of the symptoms will always be directly proportional to the overall health of the individual and the strength of their immune system. In my lifetime I have only heard of a few severe cases of any of these illnesses (in my circle of experience, not in the media). All of them were measles. All of them were children who had been vaccinated! More on that in Part 2...

There are a few illnesses for which vaccinations are given, such as tetanus and diphtheria, that are more serious. However, these illnesses have always been much more rare, so the potential for any particular person to develop serious symptoms is similar to the more common illnesses.

There was a time not so long ago when the disparity between the rich and the poor was greater, most people lived in crowded, unsanitary conditions, and access to good nutrition was limited. It is not a stretch to conclude that in those conditions a significant proportion of the population was immune compromised to some degree. The conditions that most people lived in were very out of balance and ideal for the spread of infectious organisms. Not surprisingly, in those days when cyclic illnesses moved through the population many people died, often as a result of the consequences of high fever. As a result, people have come to fear fever even though it is a normal, healthy part of our immune response.

I was about four years old when I got "the measles". The itching was one of the most irritating things
I have ever experienced, but having gone through it I now have a life-long immunity.

During the late 19th and early 20th centuries the situation changed significantly in industrialized countries. Sanitation, living conditions and access to a fresher and more diverse food supply all improved. As a result, the incidence and severity of infectious diseases declined. Advocates of pharmaceutical medicine and, more specifically, vaccinations would like us to believe that this reduction is mostly due to the advent of modern medical practices. However, the evidence doesn't support that. Most of these illnesses had significantly declined prior to the implementation of vaccination programs and the development of modern drugs. The only exception was the development of antibiotics!

In response to people who uncritically advocate the benefits of modern medicine I'm going to go one step further. According to the most recent statistics it is estimated that in the US alone 1,000 people die and another 10,000 people suffer serious health consequences of medical errors every day [see http://www.scientificamerican.com/article.cfm?id=how-many-die-from-medical-mistakes-in-us-hospitals&page=2 and http://www.healthcareitnews.com/news/deaths-by-medical-mistakes-hit-records]. These are not statistics from anti-medicine extremists. They come from prestigious medical journals. Unfortunately, this is just the tip of the iceberg. Many medical errors go unreported and the statistics we do have come almost exclusively from hospitals. We know a lot less about medical errors that occur outside of hospitals in everyday medical practice. These tend to be even more under-reported. Nor do these statistics include people who suffer less dramatic chronic health complications. It is also estimated that there may be a similar number of deaths and adverse reactions to drugs and medical procedures that are administered correctly (in accordance with accepted medical practice)!

Enough about the limitations of modern medicine, now lets look at the arguments on the other side. Opponents of vaccinations like to claim that the reduction in the incidence of diseases for which vaccinations are available would have occurred to the same degree as they have even if vaccination programs had not been implemented. This is also not true. Although the issue is very complex and it is impossible to determine exactly how much each factor contributed, there is no doubt that vaccinations have played their part. In fact, there was almost certainly a synergistic interaction between all of these factors. For instance, improvement in the immune function of the general population due to the various social factors that I mentioned probably had a significant impact on the effectiveness of the vaccines. No matter how we look at it, vaccines have definitely made an important contribution to the reduction in the incidence of these illnesses and continue to do so today.

This is the end of Part 1 of this series. In Part 2 I'm going to look at some of the pros and cons of vaccinating and introduce a couple of good resources where you can obtain more information.

A Crazy Season in the Life of an Herbalist!

Well, it's been a long time since I sat down at my computer and put any energy into this neglected child. Since April 2nd to be exact! I've contemplated it a few times, but the truth is that it has been such an incredibly busy seven months there hasn't been any time for it. Harvesting season begins in early to mid April, depending on how quickly things thaw, and ends some time in November or December when the ground freezes and I can't dig any more. This has always been a busy time for me. During the most intensive periods of harvesting, which are mid May to the end of July and late October to mid November, it is often necessary for me to devote the better part of three days per week to harvesting herbs and preparing tinctures - and that is on top of everything else that I need to do. There has always been a bit of travelling that was necessary during this time as well. Mostly to teach workshops but hopefully there is time for a holiday at some point. However, in the last few years my work has expanded into some new realms that require me to travel a lot more than I am used to. This year my travelling began on April 28th and ended on November 5th. During that time I was away three weeks in May, two weeks in July, one week in August, two weeks in September, two weeks in October, and the first bit of November. All of it was work related except for a week holiday in early September. We actually had to cancel a planned road trip to Nova Scotia in mid August because it would have been too much on top of everything else.

The interesting thing is that I'm not particularly into travelling, so it's surprising that my life has taken a turn of this nature. I'd rather just stay put and deepen my relationship with the land where I live from season to season, year to year. Nevertheless, the work that I am doing that requires me to travel is amazing and expansive, and I know in my heart that it is an important part of my path. It was a busy half year but it was all amazing. The challenge has been finding time to harvest all of the herbs that I need and fit in all of my clients on the few weeks that I am here. As it was, there were a few herbs that I wasn't able to get. In my world, that means that I have to use them less to stretch the stock that I have. When I eventually run out I won't have those herbs available until three months after I harvest them next year (three months is the minimum amount of time that I macerate tinctures).

It was a busy workshop season: Discussing black elder (Sambucus nigra) at an Herbal Field Studies workshop in early July.

This year things were even more challenging because of the weather that we had. After a record breaking, bitter cold winter and late thaw, we had a very strange spring and summer. It was much cooler than normal but not in the usual way. We do typically get a cool summer about once per decade. But those summers are usually very cloudy and wet, with very little sunshine. This year it was cloudy and wet a lot of the time, but we didn't get the days (sometimes weeks) of constant rain that we usually get during this kind of summer. On the rainy days the rain was more intermittent. We also had very few thunder storms. On the positive side, most weeks we still got at least a few sunny days. This was very important from an herbalists perspective because during years when it is almost constantly cloudy and rainy, although herbs that like that kind of weather such as stinging nettle (Urtica dioica) and coltsfoot (Tussilago farfara) do very well, herbs that don't like it such as red clover (Trifolium pratense) and common St. Johnswort (Hypericum perforatum) do very poorly. For many herbs in the latter category it just isn't worth harvesting them as the quality of their medicine is very low. Fortunately, many plants can tolerate a range of habitats that get different amounts of sunlight. Therefore, it is possible to partially compensate for unusual weather conditions by harvesting them in different locations. During hot, dry years it is often possible to find healthy populations in the part of their range where they get less direct sunlight. In these areas they will experience less heat stress and the soil will be more moist. In cooler, wetter years we harvest them in the part of their range where they get the most sunlight. Here they will get as much sun as possible and the soil will be less wet. However, during extreme years even this doesn't work for some herbs and I have to pass on harvesting them and make up for it by using more of some of the other herbs that can be used as a substitute in various contexts. This is one of the reasons why it is necessary to work with a rich and diverse group of herbs. I also usually try to harvest enough herb to make a two year supply of tincture for herbs that this is manageable, meaning the ones that I use in small to moderate quantities. This is partly so that I don't have to harvest every herb every year, but also to build some resilience into my supply of tinctures. If for some reason I am not able to get some of the herbs that I need in a particular year, there will be more choices if I have to use substitutes.

Common St. Johnswort (Hypericum perforatum) doesn't like cool, cloudy, wet years.

In our area, from mid June to mid September we can usually count on at least a few weeks of hot, humid weather with temperatures of 30+ °C (86+ °F). This year we only got a couple of days of temperatures in the 30s in June and then another couple in July. As a result, although plants that like a fair bit of sun, such as wild mint (Mentha arvensis) and wild bergamot (Monarda fistulosa), and flower earlier in the season did fairly well with the amount of sun that we had in spite of lots of rain and cooler temperatures, some of the plants that need more heat and flower later, such as peppermint (Mentha x piperita) and spearmint (Mentha spicata), really suffered from the cumulative affects of the weather. In our area they didn't flower until early September and the quality was too poor to harvest.

Wild mint (Mentha arvensis) got enough sun and produced some good medicine this year.

Another thing that stood out this summer was the continuing decline of the local honey bee (Apis mellifera) population. Around my home there are many species of clover. They all came into flower in June: first red clover; then alsike clover (T. hybridum); then white clover (T. repens); then yellow sweet clover (Melilotus officinalis); then white sweet clover (M. alba). Honey bees love many flowers, but the clovers are among their favorites. Yet, during their peak flowering in June and July I didn't see a single honey bee. A few years ago these flowers were covered in them! There is a wild hive in the woods about 400 m from my house. This year it didn't become active until early July. As their numbers increased they gradually expanded their range, but I didn't see any within 100 m of my house until the Canada goldenrod (Solidago canadensis) was well into flower in mid July. Recent evidence suggests that a major factor in the collapse of the honey bee population in much of North America is the use of a group of pesticides that are nicotine derivatives called neonicotinoids. It's typical for us to look for simple, unidimensional solutions, but as with everything in life the cause is a lot more complicated than that and due to a combination of factors. In all likelihood the bees are being killed or weakened by the combined effects of neonicotinoids and other pesticides and, as a result, the weakened individuals are also becoming less resistant to various parasites. There are probably other environmental factors involved as well, but something needs to be done about it quickly and reducing the use of neonicotinoids is a good place to start.

The population of this colony of honey bees living in a crack in an old white pine (Pinus strobus) near my home
has been significantly reduced in the last few years

Needless to say, between the travelling and the weather conditions it was very difficult for me to get all of my harvesting done this year. There were a few plants I didn't have time to harvest and a few more that weren't good enough to harvest. This has continued up to the present. Unlike the spring and summer, September and October were warmer than usual. This had it's own challenges. For instance, I had to be away from October 24th to November 5th. I needed to harvest maidenhair tree leaves (Ginkgo biloba) before I left. I have found that the best time to harvest the leaves is in the fall when they are about midway between their transition from green to gold. In the region where I live this is usually around the third week of October. However, because of the warm weather, when I went to harvest them on October 21st they were only just beginning to turn. I knew I couldn't wait until I came back because by then they would have fallen, so I harvested them that day. They weren't perfect but they were good enough.

The maidenhair tree leaves (Ginkgo biloba) started turning gold late this year because of the warm fall.
Note the contrasting yellow and orange of the sugar maple trees (Acer saccharum) in the background.

When we returned from Mexico on November 5th the warm weather was still with us. Right away I had to get to work because the aerial parts of most of the herbaceous plants had already died back and it was time to start harvesting roots and rhizomes. We need to get them done before the ground freezes and we can't dig any more. There are also a few fruits that I need to harvest at this time of year, but they have to be harvested after a couple of good frosts, so they weren't ready yet. Things started out OK. We were getting highs of around 8-12 °C (46-54 °F) and lows of 4-7 °C (39-45 °F) and not too much rain. Perfect root harvesting weather! We got to work right away.

Here's Monika harvesting stinging nettle rhizome (Urtica dioica).

Then on November 11th the temperature went up to 18 °C (64 °F) and the next day it dropped below freezing! For a few days it wasn't so bad because the the daytime temperatures were staying above freezing. But by the end of the week temperatures had dropped to January levels. I still needed to harvest several herbs and was worried that the ground might freeze before I could do them all. The unseasonably cold temperatures weren't just a stress for us. Everybody was feeling it! On Sunday morning in my peripheral vision I caught a movement outside my kitchen window. I knew it wasn't a bird that should still be hanging around here at this time of year and sure enough there was a yellow-rumped warbler (Setophaga coronata) shivering in a tree just outside the window. That was November 16th. I have never seen any species of warbler around here later than mid October. He was probably migrating through from somewhere much further north. With the lingering warm weather he must have been taking his time. That choice could turn out to be fatal!

This is a yellow-rumped warbler (Setophaga coronata), but not the yellow-rumped warbler.

As if the cold temperatures weren't enough of a challenge, last Sunday night and all day Monday it snowed. Fortunately, we didn't get that much. I can't imagine what it must have been like a little south of us in Buffalo, New York where they got completely buried! That would have definitely been the end of the harvesting season for us.

It was incredibly beautiful in the woods on Monday afternoon. The first snow. It was perfectly still and silent, and everything was covered in a blanket of white. Monika and I would have preferred to have just gone for a nice walk. But, still racing against winter, instead we went out and harvested wild sarsaparilla rhizome (Aralia nudicaulis). This herb is a colonial species with a network of rhizomes that does not leave a recognizable stalk standing after it dies back. Below the snow and fallen leaves, the only way to identify it is by the crowns with the buds of next years growth that usually sit a bit higher than the surface of the soil. Finding them is easy, but only if you know exactly where they are growing! It's simply a matter of clearing away the snow and leaves, finding the buds, and following the rhizome from that point.

Harvesting wild sarsaparilla rhizome (Aralia nudicaulis) last weekend. Note the bud in the centre foreground.

Since Monday it has been even colder. The ground is starting to freeze, but fortunately hasn't yet completely because we got just enough snow to insulate the ground a bit. Yesterday I was able to get out and harvest high bush cranberry fruit (Viburnum opulus), which are ready now that the temperature has gone below freezing. There are a few good sized colonies of these shrubs on the property where I live. But for some reason none of them produced fruit this year. They all flowered. I can only assume that there was something about the conditions when they flowered that affected their ability to produce fruit. As a result, I had to hike a couple of kilometers into the back fields in order to find an area where there was a good supply of fruit.

High bush cranberry fruit (Viburnum opulus) can't be chopped on a cutting board because they are too juicy.
They need to be ground for a few seconds with a bit of menstruum. Great colour!

Starting today the temperature is going up again and we are supposed to get rain with the temperature peaking at around 13 °C (55 °F) by Monday before it starts dropping again. That will melt the snow and warm up the soil a bit and it looks like I will be able to harvest the last two herbs that I need to get: marshmallow root (Althaea officinalis) and wild ginger rhizome (Asarum canadense). After that harvesting season will be over for this year and I'll be using the time that I have been devoting to harvesting to converting classroom courses to online courses. This is something I don't have much time for during harvesting season. I'll also have more time to put up some more stuff on this blog. It won't be another six months until the next one!

Until next spring I can spend more of my time in nature just being with a lot less doing. I'm looking forward to that. I'm also putting out some good energy for my little winged friend and others like him that lingered too long. I hope they are able to make it to the warmer regions down south!

Harvesting Ground Ivy

On June 12th I went to one of the areas where I wild-harvest herbs and harvested ground ivy (Glechoma hederacea), better know as creeping Charlie in some areas. This Eurasian species has naturalize throughout much of North America. Some people consider it invasive, especially in shady areas, but it really isn't. It can sometimes be prolific, but it doesn't crowd out other species. It often grows on shadier parts of lawns. If you notice a somewhat minty smell when you are mowing the lawn, you've probable mowed some ground ivy!

This is an herb that I use in moderate quantities in my practice - typically about 4-5 litres per year. It is a very versatile herb and I would probably use even more of it if it wasn't for the fact that it is a difficult herb to harvest in quantity due to its small size. As I still had 2 litres of ground ivy macerating and a bit more already pressed, this year I harvested 5 litres. With herbs that I use in small to moderate quantities I usually harvest a two year supply so that I only have to harvest about half of them each year, but because of difficulty harvesting large quantities of this herb it is necessary for me to harvest it annually.

Ground ivy (Glechoma hederacea) in the early spring before it starts to produce flowering stalks.
The larger, older looking leaves are the ones that have over-wintered.

Ground ivy is fairly sensitive to variations in weather conditions from year to year. In the region where I live it can go into flower any time from mid April to early May. It has a relatively long flowering period, typically flowering until late June or early July.

Although we tend to harvest the aerial parts of most herbs very soon after they go into flower, with ground ivy it is preferable to wait until a bit after the middle of its flowering period. This is because the flowering stalks that we harvest are relatively small and don't weigh very much. It is best to wait until they are almost at their maximum height. I usually harvest it from early to mid June, depending on the weather conditions in any given year.

The young stalks of ground ivy just before it begins to flower.

Fortunately ground ivy has a fairly long period when it can be harvested - typically about two weeks - because, with the unusually cool, wet weather we have been having, there haven't been very many days when the conditions are ideal for harvesting herbs. As a result, I didn't get a few of the herbs that I intended to harvest; but I had to get ground ivy because I use a fair amount of it.

This is what ground ivy looks like when it first goes into flower.

Last year the conditions were the opposite of this year. They were unusually hot and dry. As a result, I harvested ground ivy earlier; on June 5th. It was actually about a week later in its life cycle when I harvested it last year. Had I harvested it at a similar stage to when I harvested it this year it probably would have been about a week earlier, more like the end of May.

Here is ground ivy a few weeks later.

This year on June 12th I headed out to a wilderness area about 15 minutes from where I live to harvest ground ivy. As always, I began by offering tobacco to the spirits of the land and the medicine and asking permission to harvest the medicine that day. After I received permission I headed to an area where the spirit of ground ivy is very strong and there is a large healthy population.

A closer look at our friend. Notice that it has square stalks and opposite leaves, typical of the Mint family.

Although for the most part our spring was cool and wet, we did have a few short periods when it was sunny, hot and humid. The day I harvested ground ivy was during one of those periods. It was very hot that day and I had to be careful not to drip sweat onto the herbs as I harvested them. It was also the first day when the mosquito people were quite present. I rarely use mosquito repellent and only use a natural formulation that I make when I do. However, I never use repellent when I am harvesting herbs. Partly it is to ensure that the essential oils in the repellent I use don't contaminate the herb(s) that I am harvesting. But it is also another way that I give back to the land where I am harvesting. I never intentionally kill biting insects and when I am harvesting I just let them bite me. Eventually my blood will work its way up the food chain, into the soil, and even the plants that live there. The the sacrifice of the plant people when they offer the gift of their medicines is far greater than the little bit of blood that the mosquitoes take from me. In fact, I have a good relationship with the mosquito people and they bite me a lot less than they bite other people. When I'm with other people they hardly bite me at all, unfortunately for the others! When I used to have a more antagonistic attitude towards them they used to bite me as much as anyone else.

The flowering stalks of ground ivy can grow up to 50-60 cm (20-24 inches) tall, but it is best to harvest them when they are about 30-40 cm (12-16 inches) tall. We harvest about the terminal 50% of the stalk. In order to ensure that I do not have too much of an impact on the local population of this herb, I only harvest about from about a third of the stalks in any given area.

The harvested portion of two different size flowering stalks. The top one is 20 cm (8 inches) long,
the bottom one is 15 cm (6 inches).

In preparing herbs to make a tincture there are two stages that can be relatively time consuming. The first is the actual harvesting. Plants for which the harvested portion is small or whose population tends to be more spread out take a lot more time. Of course, we have to include the time it takes to travel to and from the area where we are harvesting as well.

The other stage that can be time consuming is the processing that we need to do with the harvested portion before it can be chopped up to prepare a maceration. There are some herbs from which we use the entire harvested portion. However, these are the minority. With the aerial parts of most herbs, much of the stalk is a fair bit less potent than the leaves and flowers. As a result, we usually have to remove a portion of the stalk. The difference in potency between the stalk and the leaves and flowers varies from herb to herb. The greater the difference, the greater the proportion of stalk that has to be removed and the longer the amount of time it takes to process the harvested portion. The more an herb branches, the more time this takes as well. Ground ivy is about medium in this regard. We do need to remove a fair bit of the stalk, but the stalks do not branch. With this herb it is best to remove the leaves and flowers from about the lower 2/3 of the the stalk. That portion of the stalk is removed and not used. I don't waste anything. The discarded stalks end up in my composter. If I didn't have a composter I would return them to the Earth somewhere at my next opportunity.

The same two harvested portions showing the amount of stalk that was removed.

Once the stalk that we aren't using is removed, the herb is weighed to determine the appropriate amount we need to use taking into account the potency we wish to prepare and the size of the jar that we will be macerating it in.

This is the amount of processed herb required to make 1 litre of tincture at a 1:5 potency.

Then we have to chop the herb up relatively fine before it can be macerated. With the right tools, that doesn't take very long. For more information on the specifics of making a tincture, see the Making Medicine series of posts.

Here it is again, chopped up and ready to macerate.

Ground ivy is a moderately aromatic herb. Its relatively mild flavour is somewhat minty and musky with just a touch of bitterness. If I have any left over I will dry it and use it to make a tea. I like the taste of ground ivy but some people find it a bit unpleasant. However, it is not overpowering and blends well with many other aromatic herbs.

There is not very much information on ground ivy out there. It is primarily recommended for respiratory conditions and inflammation and ulcers of the digestive tract. In my experience, I have found it to be a much more versatile herb than what you might suspect based on the information in the literature. However, this is typical. When I use an herb and really get to know it, I always find that it has many more properties and uses than what is indicated in the literature.

Rather than turn this into a super long post by getting into the uses of ground ivy, in the Herbal Resources section of my website I have provided a pdf document on ground ivy that you can download that is based on my research and experience with this herb.

Link to PDF file.

So, that wraps up my discussion of my experience harvesting my friend and colleague ground ivy. Except for the difference of habitat, the process is very similar to harvesting blue vervain (Verbena hastata), which I described in the Making Medicine series. In future posts I will discuss the harvesting and processing some different medicines that have a range of different requirements.

Harvesting Herbs: Dancing With Weather

OK, I'm back! I haven't posted anything since I returned from my back-to-back trips to Mexico and Lake Superior - and, yes, my leg is doing great! I'll provide more on that in a future post.

Unlike last year, during which the warm weather came very early in the spring and the spring and first half of summer were extremely hot and dry, so far this year it has been unusually cool and wet in the region where I live. This can have a significant influence on many plant species. Each plant has an ideal habitat that it prefers, including type of soil, moisture level, amount of sun, and climatic conditions. However, there will be a range of conditions in which it can do well and a wider range of conditions that it can tolerate. What these conditions are and how much variation it can tolerate will vary from plant to plant.

The plant life in my area can be pretty lush when there is lots of moisture like there is this year.

There is always a certain amount of climatic variation in any given region. The amount of variation in the Great Lakes region where I live is probably moderate compared to other regions. However, since around 1970 our climate has been noticeably changing - and the amount of change has been increasing with each successive decade. The kind of change is consistent with what we can expect given global trends: a progressive warming with greater extremes. This has had a noticeable impact on plant and animal species.

So, let's get back to the conditions this year. It is fortunate that, although it has been cooler and wetter, we have at least had one or two sunny days most weeks and even on some of the days that it has rained there have been sunny breaks at some point during the day. As a result, some plants that do very poorly if there has been very little sun are managing to stay relatively healthy.

Many plants that don't do well if there is too much rain and too little sunshine are still doing fairly well this year.

On the other hand, there are a few plants that are looking a bit stressed. This is particularly the case for plants, such as a few of the bedstraw (Galium) species, that grow in lower light areas that are relatively moist. Examples include cleavers (G. aparine) and rough bedstraw (G. asprellum). When there is as much rain as we have been getting this year, the typically moist areas where some of these species grow tend to be moist to the point where they are somewhat wet - and not all plants that grow in these areas necessarily like wet conditions.

Rough bedstraw (Galium asprellum) is finding many of the areas where it lives too wet this year.

As an herbalist that wild-harvests almost all of the medicines that I work with, years when it is very cloudy, rainy and cool can be challenging in a couple of ways. Firstly, most herbs need to be harvested on a sunny day and there needs to be at least one additional sunny day between the day they are harvested and the last rain. For some plants there needs to be two sunny days in between. This is because the plant tissues tend to otherwise be too wet and there are many important constituents, such the components of essential oils, that are produced in much lower quantities if there isn't much sunshine. If there are too few consistent periods of sufficient sunshine, there are also a lot fewer days when herbs can be harvested. If the timing of the sunnier periods doesn't line up with when the herbs are ready to be harvested, I may not get some herbs that year. Secondly, there are some plants, such as red clover (Trifolium pratense) and common St. Johnswort (Hypericum perforatum) that are significantly less potent during such conditions to the point where it isn't even worth harvesting them. In unusually wet (and dry!) years many plants will also be affected by mildew, making them unusable.

Red clover (Trifolium pratense) isn't happy when it's too cloudy and wet!

When the conditions are cooler, cloudier and/or wetter than usual, it is best to harvest herbs in the sunnier parts of their range where they will get maximum direct sun and the soil will be a little bit drier. In years when it is hotter, sunnier and/or drier than usual, it is best to harvest herbs in the shadier parts of their range where they are more protected from excessive sunshine and the soil will be more moist. This year, herbs such as stinging nettle (Urtica dioica), which can tolerate full sun but doesn't usually do well in it, is doing very well in more open areas.

Our native stinging nettle (Urtica dioica ssp. gracilis) is doing very well this year in more open areas.

I typically spend about one day per week harvesting the medicines from mid April to mid May; two days per week from mid May to mid June; three days per week from mid June to the end of July; two days per week in August; one day per week in September; I only harvest on two to three days in October; and then it's back up to two days per week in November. This means that during harvesting season I have to minimize the amount of days that I have a fixed schedule, such as clinic days and scheduled classes and workshops. Which days I need to harvest on depends on when the herbs reach the right stage in their life cycle for harvesting and, of course, the weather! During the peak harvesting season I do my best to allow four to five days per week when I have nothing in particular scheduled so that I can head out on a moments notice whenever the herbs and the weather align! Fortunately, a lot of the work that I do can be scheduled around my harvesting days.

This intensive harvesting schedule means that if I harvest almost all of the herbs I use and don't cut any corners to ensure that the medicines are harvested in a respectful and ecologically sustainable way, and are the highest quality possible, I can only harvest and prepare enough medicines to comfortably run clinics two days per week scheduling about five to seven clients per day. I could maybe do three days per week if I really push it, but I would rather not. These constraints are fine with me. Healing work is very intensive. If one gives oneself fully to the medicine it is very difficult to be completely present when seeing more than 15-20 clients per week. It is essential that any healer live a balanced life and look after their own health and well-being in order to be able to fully live the medicine and offer the most to those who need it.

In my practice I only run clinics one day per week. The rest of the time I do other related work such as teaching, writing, and dealing with the various responsibilities I have as a result of being on the board of directors of both our provincial and national herbalist associations. For almost two years a lot of my time has also been devoted to converting the content of courses to an online format. This will continue for a couple of years, but out of necessity it slows down during harvesting season. By nature I do best with diversity and flexibility. My work also requires that I spend regular time deepening my relationship with Nature and the medicines, whether I'm out there observing or just being.

In years where the weather conditions verge towards the extremes it can make harvesting difficult. For instance, of the sixteen herbs that I had intended to harvest this spring, I only managed to harvest ten of them. Fortunately, I didn't need as many herbs as usual. This is partly because I will often harvest enough to prepare a two year supply of tincture for herbs that I use in low to moderate quantities so that I don't have to harvest every herb that I use every year. For herbs that I use in larger quantities this isn't possible. Also, last year I used less of some of the spring herbs than usual.

 American black elder (Sambucus nigra ssp. canadensis) is right on schedule this year!

Another challenge associated with more extreme weather conditions is that it can significantly alter the life cycle of a plant. Although the timing of some species such as black elder (Sambucus nigra) and yarrow (Achillea millefolium) is pretty consistent from year to year, others can vary by as much as one to four weeks depending on the weather.

This year lance-leaved heal-all (Prunella vulgaris ssp. lanceolata) came into flower sixteen days later than last year.

Ultimately, all I can do is surrender! Herbalists have always had to learn to work with whatever Nature provides. Fortunately, I work with enough medicines that if I can't harvest a sufficient quantity (or any!) of a particular herb in any given year I usually have one or more herbs that are similar enough that I can use as a substitute. In the mean time, looking ahead at the coming weeks there is still lots of rain in the forecast. In terms of the rest of the harvesting season, I'll just have to wait and see how the summer is going to unfold. All I know for sure is it will be an adventure!

The Pros and Cons of Vitamin Supplementation, Part 3 of 3

This is the third of three posts on this topic. Part 1 was posted on November 20th, Part 2 on November 22nd.

I would like to begin here by first clarifying some of the statements that I made in Parts 1 and 2 concerning manufacturers and retailers of natural health products. I referred to certain aspects of their formulating strategies as marketing gimmicks and also suggested that in some cases manufacturers were engaging in deceptive practices concerning the quality and forms of the ingredients in their products. Sadly, this is sometimes the case and it can be very difficult for consumers to discern the relative quality of products and information that are out there.

Before looking at some of the challenges for consumers who are looking for quality information and products, I would like to put this into a broader context. Natural healing practitioners and the natural health products industry have long been innovators in terms of challenging the status quo, developing effective therapeutic protocols, and making many excellent products available. Many of these very effective therapies and products have been ignored by mainstream medicine and often challenged as ineffective or even harmful. It is true that in some cases they were, but these challenges from reductionistic medical practitioners and scientists were largely based on a perspective that anything that is not backed up by clinical studies doesn't exist. The fact that a significant proportion of mainstream medical practices and uses of drugs are not supported by clinical studies doesn't seem to matter. What matters is that many proponents of mainstream medicine will attack anything that challenges their paradigm. Nevertheless, many of the medicines and methodologies that have been used by traditional peoples or developed by practitioners of natural healing have since been scientifically verified. When they are, the scientists who do the research often claim to have "discovered" these new treatments and don't acknowledge their origins or that they once vehemently denied their efficacy and the credibility of those who used them. That being said, just like any aspect of society where there is money to be made and ego gratification to be obtained, not everything out there in the natural healing and health products world is necessarily good for us.

Varro Tyler was a respected scientist considered to be one of the worlds leading authorities on medicinal plants. He once wrote that
mad-dog scullcap (Scutellaria lateriflora) is "a nearly worthless and essentially inactive plant". Recent research has begun to verify its
traditional uses. Any experienced herbalist that has ever used this herb knows that, stuck in his reductionistic, materialistic world view,
Tyler might have known a bit about the chemical constituents of plants, but he knew very little about medicinal herbs.

Back in the 60s and 70s, the natural foods and health products industry was largely made up of grassroots idealists who believed in what they were doing and tried their best to live it. Sure, there was still some questionable information and products out there, but most of it was pretty basic and sound. If we were to take a tour of the typical health food store at that time we would have found mostly staples, the essentials of a good diet: lots of unprocessed or minimally processed whole foods. The selection of supplements was for the most part pretty basic and uninteresting. What was sometimes lacking was a good variety of organic produce, meats and dairy products. Fortunately, organic agriculture has grown significantly since then and this is no longer the case.

In the late 70s and early 80s things began to change. The industry started growing at an incredible rate and the diversity of products increased similarly. On the food end, the shelves started filling with products that looked very similar to those on the shelves of regular supermarkets. On the positive side, this was an important indicator that natural products and healing modalities were becoming more mainstream and a growing segment of the population was starting to take their health more seriously. These products provided a lot more diversity and choices for consumers and they formed a very important bridge for people who were starting to change their diet, enabling them to purchase healthier products that were very similar to what they were already consuming. However, the downside was that the shelves of health food stores and eventually mainstream supermarkets as the momentum continued through the 90s were mostly filling up with slightly more natural and healthy junk foods. Although these products are better than their mainstream counterparts because they don't contain numerous additives and are usually made from mostly whole food ingredients, often organically grown, most of them are still for the most part processed foods. They are a healthier alternative but they are not whole, natural, unprocessed foods, which is ideally what our diet should consist of. You will find most of the real health foods in the bulk foods and produce departments of these stores, which of late tend to be taking up a smaller and smaller proportion of the floor space. I'm not saying that these products don't have any value. They are a step in the right direction and have lots of benefits over mainstream food products including those I mentioned above. I even eat some of them myself and recommend them to my clients to help them transition to a healthier diet. What I am saying is that many of these foods are not as "natural" as people tend to think they are.

Natural foods and health products are not on the fringe any more. They are mainstream and they are big business! In this industry it is almost impossible for small grassroots companies to survive these days. Most of the smaller companies have been swallowed up by medium sized companies or gone out of business. A growing number of the medium sized companies are being purchased by mega corporations. A significant portion of the industry is now owned by major food and pharmaceutical companies. This shouldn't surprise anyone because it is the same pattern that is unfolding throughout the global economy. These corporations aren't stupid. Natural foods and health products have been one of the fastest growing sectors and they want a piece of the pie, or all of it if they can get it! To this end, it's much easier to acquire an established company than to start from scratch. What this means is that natural foods and health products have arrived. They have been legitimized. In many ways this is a good thing, but what it means for this industry is that it is now infused with corporate values. Although many people that work in this industry still have a lot of the idealism that was characteristic of the past, a growing number of them aren't there because they believe in it. They are there because it's a good business.

With the infusion of corporate values into the natural foods and health products industry comes a lot of sophisticated strategies aimed at increasing the bottom line. Sometimes this translates into cutting corners on product quality. It has also resulted in some unscrupulous marketing strategies such as greenwashing.

One of the things that tends to characterize people who are interested in improving their health is their hunger for information. Companies in this sector have used this to their advantage by flooding the market with information on various dietary strategies, nutrients, herbs, and other related topics and products. It is not an exaggeration to say that most health-related information that is available in magazines and a significant amount in books is essentially advertorial of one kind or another. Some of the information might still be useful, but it is very difficult to determine what is good quality information when most of it is at best very biased, and sometimes completely inaccurate. To make matters worse, the people who consumers rely on for information, natural health product retailers, typically get most of their information from sales representatives, product literature, and a lot of those magazines that are publishing advertorials. I'm sure the majority of the people working in health food stores sincerely want to help their customers, but most of the information that they have access to is dubious and they usually don't have the necessary training to be able to filter out the good stuff from the bad stuff. Even natural healing practitioners often buy into a lot of the inaccurate information that is out there. This is particularly true of practitioners who sell natural health products because they are obtaining a lot of their information from product literature as well.

Once more I want to emphasize that I am not suggesting that most natural health products are poor quality or that manufacturers, distributors and retailers are deliberately trying to deceive consumers. Although it is true that a lot of the dubious information out there ultimately comes from someone who is attempting to manipulate consumers in order to increase their profits, most of the people down the line really believe that this information is accurate and helpful to people  and some of it is! The challenge is that most people don't have the tools to be able to assess the quality of the information. As an herbalist, I can honestly say that most of the information out there on herbs is inadequate and often inaccurate. However, unless you are an experienced herbalist you aren't going to be able to recognize this. Everyone can't be an herbalist. That is why one of the most important roles of herbalists is as educators. We need to get good quality information out there to help people to be able to make informed choices.

Now let's get back to the original point. It can be very difficult to determine what constitutes a good supplement regimen. On the one hand, we have extreme supplement advocates who, whether for business or ideological reasons or both, would have everyone popping hundreds of pills per day. At the other end of the spectrum we have old school reductionists and food purists who believe that supplementation is unnecessary unless a deficiency is confirmed. In between we have just about every other possible opinion.

In considering a person's nutrient requirements there are basically four different ways of looking at it:
  1. Based on the minimum amounts required to prevent a deficiency disease. This perspective used to be common among medical doctors and dietitians. It is less so today as it is now clear that there are other negative health consequences that can be demonstrated when a person's intake of a particular nutrient is low well before the point where the symptoms of a deficiency disease will manifest.
  2. Based on the amounts that occur in a "normal" diet of a "healthy" population. This is more typical of medical doctors and dietitians today. It is problematic because what is average is not necessarily what is natural or ideal. What is currently considered "healthy" by practitioners and advocates of mainstream medicine is probably not as healthy as they would like to believe.
  3. Based on optimum requirements for overall level of health and well-being. This is difficult to determine and could vary considerably between different people.
  4. Based on therapeutic doses. This is not something that should be advocated for daily consumption. When the dose of an individual nutrient is increased beyond the range that it is utilized for nutritional purposes, its action becomes less nutrient-like and more drug-like. Taking nutrients in therapeutic doses can be an effective element of an overall treatment protocol, but it is not nutrition.
Many medicinal herbs and spices, such as rosemary (Rosmarinus officinalis), are loaded with nutrients and antioxidants.

In my clinical practice I have found that what works best is to strive for optimum nutrient requirements. This should primarily be accomplished through eating a good diet as I discussed in the first part of this series. In particular, it means eating lots of vegetables and moderate amounts of fruit. However, for reasons that I stated previously, namely variations in individual requirements and the high levels of stress and toxicity that are endemic in contemporary Western society, I have also found that some level of supplementation is preferred if one wants to achieve some level of optimum health and well-being. The basic regimen that I recommend is as follows:
  1. A low potency multivitamin and mineral supplement as I discussed in part 2 of this series, taken once a day with breakfast. This helps to ensure that we are getting what we need on a daily basis. The higher levels of B complex vitamins and certain minerals also help to address increased nutritional requirements due to stress, as well as provide some level of support for immune function.
  2. To help protect our body from the harmful affects of toxicity and support immune function, I recommend some degree of supplementation with antioxidants. I primarily recommend vitamin C, 400-600 mg once or twice a day. If only taken once a day it should be taken with dinner to separate it from the vitamin C taken at breakfast as a component of the multivitamin. It is best to take vitamin C in the form of mineral ascorbates rather than ascorbic acid because the diet of most people in our society tends to be acidic and ascorbic acid will increase our acid load. Mineral ascorbates are not acidic. Calcium, magnesium or mixed mineral ascorbates are best. Sodium ascorbate is not recommended because we already tend to consume way more sodium than is good for us. It is also important that a vitamin C supplement contain a decent dose of antioxidant polyphenols, such as flavonoids, anthocyanins and proanthocyanidins. These are mutually synergistic with vitamin C. I also recommend vitamin E. 200 IU is sufficient for most people. It should be natural vitamin E, preferably in the form of mixed tocopherols. Vitamin E works best if taken together with 50-100 mcg of the mineral selenium. The vitamin E and selenium are best taken once per day with dinner. They must be taken with a meal that contains fat.
  3. For people who live in the temperate regions of the northern and southern hemisphere, I recommend supplementation of vitamin D. Typically, I recommend 2,000 IU per day from October to March (April to September in the southern hemisphere), and 1,000 IU in April and September (March and October in the southern hemisphere). Anyone who does not spend much time outdoors should take 1,000 IU in the summer as well. However, anyone who wants to implement a healthy lifestyle should try to spend as much time as possible being active outdoors  in a natural setting as much as possible. For vitamin D production and many other reasons, it is best not to wear sunglasses all of the time when outdoors during the summer. Sunglasses aren't good for our eyes anyway. Of course, these recommendations are reversed for people living in the southern hemisphere where the seasons are opposite. Also, keep in mind that requirements of vitamin D supplementation is going to be lower at high altitudes and higher for darker skinned people. It's also going to be lower for people who traditionally eat foods that are high in vitamin D such as fish liver.
  4. In the contemporary Western diet, the fat content of our diet tends to be high in saturated fats of animal origin and plant-based oils that are high in omega-6 fatty acids. Ideally we need to reduce these and increase the proportion of monounsaturated and omega-3 fatty acids. Traditionally, animal fats in our diet came from seafood or wild game and livestock that ate a natural grass-based diet. Today, livestock are primarily fed an unnatural diet designed to speed up their growth rate and fatten them up. They are also a lot less active. The result is that their tissue contains more fat and it is primarily saturated with very little omega-3. Consumption of large amounts of fish and wild game is no longer recommended due to environmental contamination and ecological issues. As a result, the easiest way to increase omega-3 consumption is through the use of plant-based vegetable oils. By far the best source is organically grown, raw flax seed oil that has been processed without exposure to heat or oxygen, stored in dark bottles and refrigerated. Other plant sources tend to have lower levels of omega-3 relative to omega-6, monounsaturated and saturated oils. Consuming nuts and other foods that contain them is still good in moderation. Olive oil, which is a mostly monounsaturated oil, has been found to have many health-promoting benefits as well. Nevertheless, we still need to increase the omega-3 oils in our diet and flax seed oil is the best option. I don't recommend fish oils because they are subject to environmental contamination and because of the way they are processed they tend to be rancid. Although the negative health consequences of consuming rancid oils has been given less attention than trans-fats and animal source saturated fats, it is almost certain that rancid oils pose almost as much of a health threat as trans-fats. The other issue with fish oils is that several major studies that have looked at the amount of fish and other marine animals that are being harvested from the ocean have unanimously concluded that commercial fishing at anything close to current levels is completely unsustainable. The omega-3 issue has been given a lot of attention in recent years and many foods are now claiming to be "fortified" with omega-3 oils. This is another marketing gimmick. Omega-3 oils are extremely unstable in the presence of light, heat and oxygen, and adding them to various processed foods means that they will be rancid. As a result, I recommend a dietary supplement of 1-2 teaspoons of good quality flax seed oil per day. This should never be cooked but can be added to cooked foods on our plate as long as they are consumed right away. It is important to recognize that consumption of polyunsaturated oils increases our daily requirements for vitamin E and selenium.
This is the basic supplement regimen that I recommend. In my life and my practice I have found it to be a very useful adjunct to a good diet and healthy lifestyle. It is not going to meet everyone's needs exactly, and I sometimes recommend additional supplements or higher doses for specific issues. For example, anyone suffering from chronic auto-immune or inflammatory conditions will benefit from higher doses of vitamin D and antioxidants, especially ascorbate and polyphenols.

Blueberries are a very rich source of polyphenols such as anthocyanins.

We can also increase the antioxidant content of our diet by increasing consumption of leafy green vegetables, and fruits and vegetables that have a deep orange, red, blue or purple colour. It is not necessary to consume exotic "superfoods". This is also a marketing gimmick. All plants are anti-oxidant to some degree. It's true that some are considerably more antioxidant than others, but pretty much no matter where we live their are fruits and vegetables that are very high sources of antioxidants. For instance, it doesn't get much better than dark blue and purple berries like black raspberries, blackberries, blueberries and bilberries, which grow and are cultivated throughout the temperate regions of the northern hemisphere. It doesn't make sense to consume exotic plants from foreign countries where we don't know for sure whether they are destroying the environment when growing or wild-harvesting them, they must be transported long distances, and they are usually a lot more expensive.

That is my take on supplementation. It's not going to be perfect for everyone, but it's a good basic template which we can work with and fine-tune in order to meet our individual needs. Of course, there are lots of other opinions out there. All I can say is that these recommendations are supported by the limited research that is available, and more importantly, I have found that they work in my life and my practice.

The End of an Era!

Wednesday was a typical day for me in many ways. I spent the better part of the day teaching a class like I have thousands of times before. But what was different about this past Wednesday was it wasn't just any weekly class. It was the last one!

This past January we began the process of converting most of the content that I used to teach in a weekly class format into online courses. On Wednesday I taught the last class of the last course for the last group of students who are going through our program in the weekly class format. Afterwards I did what I do at some point almost every afternoon: I took my dogs for a walk through the fields and forest on the land where I live. As always, I sat down in one of my favourite spots and spent some time just being. While I sat there I also contemplated how much things have changed since I started teaching.

I taught my first course back in the spring of 1987. During the last few years of the 80s I taught sporadically; mostly one off lectures and weekend workshops. In the first half of the 90s I taught much more regularly, but still primarily limited to weekend workshops. Then in August of 1995 I got this idea that maybe there were people who were interested in taking a course run as a series of weekly evening lectures. Thus Healing With Herbs was born. It has gone through a few changes over the years but it is still the primary introductory level course that I teach. I should say it was ... until it went online this past January.

I had wanted to start Healing With Herbs in early September and I was only able to find one lecture room available on such short notice. It was a small room that only held 18 people, but I figured that would be enough. I only had a few weeks to promote the course and this was an experiment anyway. Well, 28 people applied to take the course and I had to turn 10 of them away! I ended up running it again in January and then in April with about 25-30 students in each session. Many of the students asked me to create additional courses, so the following school year I ran Healing With Herbs three times again, but each term I added a new course as well on a different night of the week. This was the beginning of teaching weekly classes for me; the beginning of a phase that ended this past Wednesday.

Here I am teaching a field workshop at
Mono Cliffs Provincial Park in the mid 90s.

By June 1997 some of my students were asking if I would create a complete herbalist program. I contemplated that over the summer and by the fall decided that it was in alignment with what I needed to do. Over the next 12 months I continued to introduce new courses while working on the curriculum for the entire program. After a couple of false starts, Living Earth and the Traditional Herbalist program were finally born in September 1998.

Initially we ran classes on weekday evenings and weekends. By 2000 students started asking for weekly daytime courses and we ran these as well. Within a couple of years enrolment in the evening and weekend courses started to drop and I switched exclusively to weekday courses.

The gradual change in the preferred class schedule of most of my students was interesting. It seems that in the 90s most of my students were working regular full-time jobs. They tended to be older people who were either taking courses for personal interest, or those who weren't happy with their work and were considering changing to a new career that better reflected where they were at in their lives. In the 2000s that started shifting. I was getting some younger students fresh out of high school or university who were still living with their parents. For the first time young people were considering herbalism as a first career! Many of the other students either weren't working full-time, had jobs with flexible hours, or were self-employed.

There were other interesting changes to the demographics of my students over the years. For instance, when I started teaching the age of my students ranged from mid 20s to late 60s with the majority of them being in their mid 30s to late 40s. There was also a 50/50 split between men and women. Over the years the lower age limit dropped as I started getting some students in their late teens and early 20s, and the overall average age dropped as well. In addition, the percentage of women increased. So now the vast majority of my students are women in their early 20s to early 30s. Although I still get a few men in some of my general interest courses, in the last few years I haven't had any commit to the full herbalist program. Since we began putting our courses online in January things have changed yet again. For one thing, there has been a higher percentage of men enrolling. We'll see how many of them end up committing to the herbalist program. I'm sure there are a lot a factors that have led to these changes over the years. I don't claim to understand them all, but I am glad that younger people are being drawn to this path because they are the future!

So now I have come to another major shift. I'm older and most of my students are a lot younger. They have grown up in a very different world than me; a digital world. It's a world of iPhones, text messages, Facebook, Twitter ... and, yes ... blogs! This world means nothing to me, but it's not something I can completely ignore. A big part of my path is to bring the medicine to the people and that means I have to be able to bring it to where the people are. Still, I have no interest in spending endless hours talking or texting on a cellphone, or checking out Facebook. I spend way more time on a computer than I would like to just doing my day-to-day work. I would much rather be out in the woods.

It seems that these days it is becoming increasingly more difficult for the majority of the people who want to learn about herbalism to commit to the more rigid structure of weekly classes. Online courses are becoming more practical and more appealing to people, and they are workable for people with a great diversity of life situations. We also now have the technology to make the experience of doing online courses as close as possible to being in class, with a few added advantages as well (like being able to listen to parts of a lecture over again if you miss anything). Yet I've never been a fan of distance learning courses, not only because there is so much experiential content that can't be done in that format, but because the medicine is a living thing. It can't be learned from a bunch of words. We need to plant our feet firmly on the Earth and be in it!

how to immerse ourselves in the medicine!

Traditionally, herbalism and other healing traditions were learned by apprenticing with an elder. That is by far the best way to learn, but for many reasons it doesn't work well in our modern Western world. I've always tried to compensate for the limitations of teaching in a classroom framework as best I can. In particular, I've done my best to incorporate as much experiential content in my courses as possible. During this transition to providing a lot of online courses I will have to develop new ways to accomplish this. Of course, there are still workshops that can't be done online and will run as before. In addition, the remainder of the experiential and clinical content will be incorporated into week long intensive workshops. I actually prefer the longer intensive format to weekly classes. But the most important thing that I wish to convey to all students and herb enthusiasts of the digital world, just as I've had to convey this message in the past, is that to truly get herbalism it is essential that we develop a living relationship with the medicines that we are learning about and using. That means learning where they grow; how to identify them; talking to them; meditating with them; harvesting them; and making various preparations from them. Anything we can do to expand and deepen our relationship with them is beneficial and necessary. Healing comes from our Earth Mother and our interconnectedness with all of the living beings that we share this life with. It doesn't come from books or the Internet! Taking good quality courses with knowledgeable and experienced herbalists is essential for anyone who is serious about this, but connecting with the medicines is just as, if not more important. They are two sides of the same coin.

Welcome to the medicine!

Making Medicine, Part 1 of 5: Wild Harvesting Blue Vervain

This is the first of a series of five posts in which I am going to use the process of wild harvesting and making a fresh herb tincture of blue vervain (Verbena hastata) as an example to explain in detail the process of making medicine. You'll have to excuse me for having changed the title a few times. As I've been writing these posts, they've become longer and more detailed and less about blue vervain and more about making medicine in general. There are a lot of aspects of this process that I realized needed to be explained in detail. So this has been an evolving process.

A week ago, Monika (Monika Ghent, my partner and the Living Earth online course supervisor) and I went harvesting blue vervain. I decided that this would be a good herb to feature in in this series because the process is pretty typical for an herb for which we harvest the aerial parts. Also, being a wetland species, it allows me to address a couple of issues that are particular to harvesting in wetlands.

The home of blue vervain (Verbena hastata).

Back in the early 80s when I first started exploring wild spaces and eventually herbs in the rural areas beyond the boarders of Toronto where I lived, I used to look at detailed maps of the surrounding area to look for wild spaces where there weren't any roads and hopefully no development (that was before the Internet and Google Maps). When I found something that looked promising, my friends and I would drive around the area to get a sense of the landscape and determine if there were any trails accessing the area. In the winter I used to hike along the course of a creek near where I lived by walking on the ice. One winter day when we were exploring a new area I suggested that it would be easier and more interesting to access the area by walking on the ice along a river that flowed through. We didn't get as far following the meandering course of the river, but we didn't care. I have always preferred quality over quantity. After that day doing this became a regular activity for me. Sadly, for the last decade or more the winters in my area have been much warmer and the rivers rarely freeze. Occasionally when they do the ice is usually too thin to walk on.

The summer following our first river ice excursion we were heading out to explore a provincial park not too far away. We wanted to avoid most of the people and explore areas that weren't easily accessible by trails. I suggested that we walk up the river. So we put on old running shoes without socks and walked up through the river. We called it "water walking" and I've done it ever since. In the early days the only drag about it was the water sloshing around for awhile in our running shoes when we left the river. For a couple of years in the early 90s I took a bunch of workshops in New Jersey with Tom Brown. The first time I was down there a few people were wearing these really cool sandals that had adjustable Velcro straps. They were Tevas of course! They weren't very common yet and I had never seen them before. I realized at once that these were the perfect all-terrain footwear for use in warmer weather, and in particular for water walking. They were the one piece that was missing from water walking. I bought my first pair 20 years ago. I'm still on my second pair. That's pretty amazing considering they are about the only footwear I use (when I'm not barefoot) during the warmer months of the year. I wear them through just about everything when I'm harvesting, hiking, canoeing or camping.

So now let's get back to wild harvesting. Wetland plants often live in areas that are not easily accessible. The plant growth can be very thick and difficult to get through. There can also be deep muck that is hard to walk in. There is also a particular kind of grass that grows in wetlands that we call "sticky grass". I don't know what species it is. Grasses can be difficult to identify and I haven't devoted any energy to learning the many grasses because I don't use any of them. What is particular about sticky grass is that it has a row of tiny barbs along the mid vein of the blade that slices your flesh. If you walk through it with exposed skin you will get numerous cuts that are like paper cuts. It's not very pleasant. With these challenges in mind, in the early years when I first started wild harvesting the medicines I realized that the best way to access wetland plants is by water walking along the course of a creek or river, or along the shore of a lake. Of course it only works when the water isn't too deep. Another concern is that we have to be very careful not to step on any flat rocks because there are often fish, crayfish or other aquatic animals living underneath them.

So on July 1st Monika and I headed off water walking down a river that is not too far from where I live. Monika needed to harvest blue vervain and yarrow (Achillea millefolium), both of which are common along the banks of the river. That day I only needed blue vervain.

Whenever I pass through wild spaces I am always keeping track of lots of information: How healthy is the ecosystem? Which plants are growing there? At what stage are they in their life cycle on that particular date of that particular year? Do any of the medicines I use grow there and, if so, what is the maximum sustainable amount that can be harvested? What mammal, bird and other animal species live there? When I get home I record all of this information in a data base and update it every time I'm in the area. In this way whenever I need to harvest a particular herb, I have a quick reference to locations where it grows and approximately how much I can harvest at each location.

While I'm moving through the landscape I keep my mind quiet and tend to use my peripheral vision most of the time so that I can be aware of as much of what is going on around me as possible. Fairly soon after we started down the river last week I noticed a flash of red way off to my right in a clearing between some cedars. To my surprise I noticed some Oswego tea (Monarda didyma) that was just starting to bloom. It was early for these parts, but most species are blooming two to three weeks early this year because of the heat and the drought we have been experiencing. Oswego tea isn't very common in southern Ontario. It is much more common south of the Great Lakes. It only grows in a couple of the areas that I frequent and this was only the second time that I had seen it in bloom. Luckily I had my camera with me that day. In our area wild bergamot (Monarda fistulosa) is fairly common and that is the species that I use. When I first started using wild bergamot there was almost no information on it in the literature. There was a bit of information on Oswego tea and the few references to wild bergamot usually just said that it was very similar to Oswego tea. It is not uncommon for plants in the same genus to have very similar properties. Because several sources had made this comparison, I had assumed that they probably taste very similar. Then one day a few years ago Monika and I were walking along a deer trail on the bank of the same river further upstream from where we were last weekend. As we were walking I picked up a strong scent of wild mint (Mentha arvensis). I looked around where we had been walking and all I saw were some baby wild bergamot plants. I tasted a leaf and sure enough that was where the smell was coming from. I then realized that they weren't wild bergamot (although at that stage they looked almost identical) but rather Oswego tea. So it turns out that although Oswego tea is very closely related to wild bergamot, it tastes almost identical to wild mint. That means that the components of its essential oil are more similar to wild mint and therefore its medicinal properties are also probably closer to wild mint than wild bergamot. It seems that the information I had read was based on an assumption, not on experience.

Blue vervain grows along the edges of wetlands, rivers and lakes. In my area it rarely grows in large groups. It tends to grow singly or in groups of a few plants along the edge of the water or a bit further back in areas where it is wet in the spring and the soil remains fairly moist through the summer. As a result, it is necessary to travel some distance along the edge of the water to get a decent amount, especially since we don't harvest all of the plants.

Blue vervain can tolerate a wide range of light conditions. It prefers to grow in locations where it will get direct sunlight 20-100% of the day, although 40-80% is ideal. In very hot dry years when the water level where the plant is growing is very low, it is best to harvest it in areas where it gets direct sunlight 20-40% of the day. On the other hand, in cool wet years it is best to harvest this herb in areas where it gets direct sunlight 80-100% of the day.

On this trip we were able to harvest a larger percentage of the plants that were ready because it hadn't been flowering for very long and only about a third of the plants were blooming. This year I only needed to harvest enough to make 2 litres of tincture because I made extra last year. I had already prepared 1 litre a couple of days earlier from a different location. Monika needed to make 2 litres as well. We had to water walk about 2 km along the river to get enough for both of us. In years when I need a fair bit I usually have to harvest at two or three locations to get what I need.

A closer look at the flowering spikes.

Blue vervain is harvested at the beginning of it's flowering period. The best time is from a few days to a week after it goes into flower. However, since all of the plants don't go into flower at the same time, generally the best time is one to two weeks after the first plants go into flower. In the area where I live, that is usually the second week of July. It was earlier this year because of the very hot, dry weather. It can be harvested a bit later, but like most plants the internodes (the sections of stalk between the nodes, the points where the leaves are attached to the stalk) get longer. This results in a higher stalk to leaf and flowering spike ratio and therefore a greater amount of stalk that needs to be discarded when we separate the usable from unusable portions of the herb. Also, the later we harvest it, the less time the plant has to produce more flowering stalks and reproduce. Typically we harvest the terminal 30-40% of the herb because this is the most potent part and it minimizes the amount of stress on each plant to regrow.

and the plant is on the bank, so it looks about 6-8 inches taller than it actually is.

We had a great time water walking that day. It was quite warm, but a few degrees cooler than it had been. The sun was very strong, but travelling through the river there was a fair bit of shade. Water walking is great on hot days because walking through the water helps to cool us down. We also enjoyed the songs of many bird species and met a few friends along the way, both in and out of the water.

Some of the other visitors to the river on that day were
Canadian tiger swallowtail butterflies (Papilio canadensis) and...

...white-tailed deer (Odocoileus virginianus). We didn't see any deer but we heard them
bounding off as we approached. I usually only see them when I'm harvesting alone.

This is the end of Part 1 of this series. Later this week I'll post Part 2, in which I will be discussing preparing the blue vervain that I harvested in order to make a fresh herb tincture. In the third post I will discuss making the maceration; in the fourth, different kinds of equipment that are available for pressing and filtering tinctures; and in the fifth, the actual process of pressing and filtering the maceration to make the tincture. In the last post I will also provide information on the properties and uses of blue vervain.
