Closing the Harvesting Season

I've been getting a lot of people asking me when I'm finally going to finish the three part blog series on The Vaccination Controversy. After several years of repeating the same pattern, I finally have to admit to myself that from the middle of April until the end of November my intense travelling schedule and harvesting herbs take up so much time that it doesn't leave me a lot of opportunity for writing. I'm not complaining. I'm following my heart and my path and love my work and still able to spend a lot of time just being with the plants and Nature. It requires prioritizing and setting boundaries. Following our heart, allowing time to just be and the quality of our relationships with people (human and non-human) and the world we live in is how we cultivate quality of life and allow space for healing. If I don't allow that in my life, how can I possibly help other people to do it? So, some things (like writing!) rarely get done during the busier months.

It's been a great spring, summer and fall! Lots of experiencing, learning, harvesting medicines and doing what a herbalist does. My travelling schedule for the year ends early to mid November and now I'm spending a lot of time harvesting the last of the root herbs that I need before the ground freezes for the winter. Judging by the way things are flowing, that will probably be in a week or two in this area.

Harvesting valerian root (Valeriana officinalis).

Today I harvested valerian root (Valeriana officinalis), marshmallow root (Althaea officinalis) and dandelion root (Taraxacum officinale). Tomorrow I'm going to harvest wild sarsaparilla rhizome (Aralia nudicaulis), wild ginger rhizome (Asarum canadense) and a bit more valerian root.

My friend Canada goldenrod (Solidago canadensis) has offered me the opportunity to work with a different expression of his medicine.

I am going to harvest some of the rhizomes and roots of goldenrod this year so that I can deepen my relationship with this amazing herb.

The last couple of years I've been feeling called to start working with the rhizomes and roots of Canada goldenrod (Solidago canadensis). Up to this point I've only used the aerial parts of this herb. I'm also going to harvest a bit of Solidago so that I can begin to learn this new medicine. After that I'll be done harvesting for this year – and just in time!

Washing marshmallow root (Althaea officinalis) in our laundry tub.

Since I make my tinctures from fresh herbs I need to harvest enough of each of these roots or rhizomes to get through at least 15 months: 12 months until I'm able to harvest them again next year and 3 additional months until next years tinctures will be ready because I allow them to macerate for at least 3 months before I press them [see: Making Medicine, Part 3 of 5]. Therefore I need to know how many bottles of each of these tinctures I still have on hand and how much I typically use in a year in order to determine the quantity that I need to harvest. I'll usually add an extra litre (or half litre for herbs I don't use as much) to be safe. For herbs that I used 3 litres or less per year I will sometimes harvest enough for 2 years so that I don't have to harvest every herb every year.

Dandelion root (Taraxacum officinale) washed and ready to chop. Note that dandelion maintains a rosette of smaller leaves through the winter.

I keep some of the younger leaves that are in good shape and include them in my dandelion root tincture.

Although the travelling that I do is related to my work and involves hanging out with great people in great places doing great things, I am happy to be at home for the next 5+ months. I'll be able to work on some of the other things that I can't seem to manage the rest of the year like doing a few blog posts (including hopefully being able to finishing the series on vaccinations!) and continuing the process of converting some of our classroom courses to an online format. The latter tends to take up most of my time through the winter months.

Stay tuned! More to come...

Chaga and the Wild Harvesting Dilemma

There are many wild spaces where I love to walk and, when necessary, harvest herbs. Whenever I explore a new area or trail, I keep a record of what species grow there. For those herbs that I use in my practice, I will also estimate the approximate amount (in litres of tincture) that can be sustainably harvested from the area of any species that are growing in sufficient quantity. Since plant populations change, I update these records every time I visit an area. As someone who wild harvests almost all of the medicines that I use, this information is very important to me. I maintain a data base in which I keep track of it.

Every year I try to visit a few new areas. This is partly because I want to deepen my relationship with the region where I live and one of the ways I do that is to get to know its diversity of landscapes and ecosystems. However, in exploring new areas I am also keeping track of the medicines that grow there. I like to have as many locations as possible to harvest each of the medicines that I use so that I don't have to harvest them in any particular region more than once every few years. I am extremely anal about respecting the medicines and making sure that they are harvested in a sustainable manner. I have written about this in more detail in my post Wild Harvesting Herbs.

In my practice I use several medicinal fungi. One of the fungi that I harvest is clinker polypore (Inonotus obliquus), better known these days as chaga. The name chaga is an anglicized version of the Russian version of the name of the fungus in the language of the Komi people of central Russia. Since this fungus has been popularized as chaga, very few people know its English name.

Clinker polypore (Inonotus obliquus), better known as chaga.

Chaga is a fungus that grows primarily on birch trees (Betula spp.) in the region where I live. It has been used for various purposes by many traditional peoples throughout the temperate and subarctic regions of the northern hemisphere where it grows. Until the last decade or so, most people in our society had never heard of it. However, it has become popularized in recent years, which is not a good thing! This fungus grows very slowly and is difficult to cultivate. In addition, so far the medicinal properties of the cultivated fungus are significantly inferior to the wild harvested fungus. Another concern is that this is not your typical wood rotting fungus. Most of the conks or bracket fungi that grow on living and dead trees are actually the reproductive organs or fruiting bodies of organisms that grow as a network of filamentous mycelia beneath the bark or through the wood. When we harvest the fruiting body of a fungus, we are not harvesting the main part of the organism. However, chaga doesn't grow this way. The part that appears growing out of the side of birch trees is not the fruit. It is the actual fungus. Chaga rarely fruits and usually only after the tree dies. So, when we harvest chaga, we are harvesting the main body of the organism.

When walking through areas with a lot of birch trees, I used to see a fair amount of chaga. However, in the last couple of years what I am mostly seeing is a lot of trees from which the chaga has been removed and very little chaga itself. This is not simply a matter of a few people harvesting some for personal use. With the popularization of this fungus it seems that there are some people who think of it as a free resource that they can harvest at will in order to make some money. What I'm finding is that most of the people out there harvesting chaga are doing their best to gouge every last bit of it out of the tree. Remember, in this case they aren't just harvesting the fruit and leaving the organism intact. They are harvesting the whole fungus! In addition, they are doing a lot of damage to the trees that it grows on, leaving gaping wounds through which the trees can easily be affected by insects or disease.

When I harvest chaga, I only harvest it in areas where it is plentiful; I only harvest from a small percentage of the fungi growing in the area; and I only harvest part of any given conk and leave 50% or more of it intact. What I'm seeing out there is the result of people harvesting every fungus they can find and doing their best to completely extract it from the tree it is growing on. Needless to say, given that chaga rarely fruits and grows very slowly, this fungus is rapidly becoming scarce in the more accessible areas where it was once relatively common.

Chaga harvested correctly: not cutting too deep and leaving more than half of the fungus intact.

It is ironic that the demand for chaga is due to a growing interest in "natural healing". However, this is the antithesis of what natural healing is really about! Natural healing is about cultivating more balanced and harmonious relationships with ourselves and the world we live in. There is nothing balanced or harmonious about the consumerism driven and disrespectful way that chaga is being torn from the landscape. This is something that many people still don't get. Our lack of health in body, heart, mind and spirit is largely due to how we interact with the world. We live in a society that is way out of balance and as long as we continue to perpetuate the unsustainable paradigm that underlies the status quo we will never really be healthy!

One of the many fallacies of the current Western world view is that we are individuals. It's all about me! It's OK to rape the ecosystem to provide me with what I want. In truth, there are no individuals. Our life depends on the life of our Earth Mother and all of the beings that we share this life with. Everything we do affects everything else and will inevitably come back to bite us if it isn't done with respect and wisdom.

If we are trying to live "green" or "natural" we have a responsibility to investigate the reality behind the latest "green" or "natural" products. We can't necessarily trust the word of anyone who is trying to sell us something. That doesn't mean that they are always manipulative or deceptive - but they often are. Even people who mean well are less likely to dig too deeply into something if their livelihood depends on it. Inevitably, we need to do some research for ourselves. For example: electric cars aren't green or sustainable if they use electricity that is produced by coal plants; solar panels are not green or sustainable if it takes more energy to make them than they will produce in their lifetime, or manufacturing them requires the use of rare and/or toxic elements; shipping exotic "superfoods" half way around the world when there are foods of similar or better nutrient density growing in the area where we live is not green or sustainable - and who knows what environmental transgressions may have been committed where they were grown or harvested? Farming and harvesting practices are not something we can easily verify for plants that come from distant regions. Similarly, wild harvesting foods or medicines on a commercial scale is almost always unsustainable.

Getting back to chaga, the use of this fungus has been popularized in several books and articles, and by the people selling it. As a result, it has become one of the latest and most popular fad herbs. Proponents of its use are recommending it be consumed as a tea and that it be drunk liberally. Some people recommend drinking the tea several times per day for many months or even indefinitely. Looking at the bigger picture, there are several concerns with this scenario. Firstly, chaga is the strongest medicinal fungus that I have used. It is not appropriate for liberal use on an ongoing basis. Like all medicines, it needs to be used with respect. Secondly, using it as a tea requires that it be used in much larger quantities compared to using it as a tincture because the amount of herb required per unit dose is much larger for teas. With the amount of chaga that will keep someone in tea for a few weeks, I can make enough tincture to supply my entire herbal practice for several months! I realize that it was traditionally used as a tea, however, I have found the tincture to be as or more effective at least when prepared by the method that I use (for more information see my previous post Making Medicine, Part 3). Finally, because of the way it grows, chaga simply can not be sustainably harvested on any kind of scale. If we want to harvest a fungus on a very limited commercial scale, it should be one that is very common and produces abundant annual fruitings that can be harvested while leaving the fungus undisturbed. An example of a fungus that might possibly fit into this category is birch polypore (Piptoporus betulinus), which has some similar properties and constituents as chaga, although they do have there differences. However, even "limited" commercial harvesting is not really sustainable because who is going to control how many people are doing it and how much they are harvesting? We're not talking about a village healer harvesting it to supply the needs of a small village in a remote area. If there is a demand for it and money to be made, it won't be long before the amount being harvested reaches detrimental levels. Harvesting the fruiting body might not kill or harm the fungus, but it will reduce its rate of reproduction. In reality, the only fungi that should be sold commercially for medicines and especially for foods (since they are consumed in much larger quantities) are those that have been grown commercially - certified organic of course!

Saying that wild harvesting medicines is unsustainable might sound like a contradiction coming from an herbalist who uses almost exclusively wild harvested medicines! However, what I am saying is that there are very few herbs that can handle being wild harvested on a commercial scale. A few herbalists wild harvesting herbs for their healing practice and a few more herb enthusiasts harvesting some herbs for personal use is sustainable if they are harvesting the herbs in an ethical manner. In fact, these days most herbalists don't wild harvest very many or any of their medicines. There are many reasons for this. One of the main reasons is that it is extremely time consuming. At the most, if I harvest the medicines in a respectful way I can only harvest enough to make a sufficient amount of tincture to practice two full days per week (6-8 clients per day)! Personally, I only practice one day per week. The rest of the time I am teaching and doing other work. Even practicing one day per week a significant proportion of my time is devoted to wild harvesting from April to November. During the peak harvesting periods (May to July and November) it takes up the largest proportion of my time.

There are still a few herbs that I either can't harvest in sufficient quantities to meet the needs of my practice, or for which I haven't found a suitable substitute that grows in the region where I live. I need to purchase these herbs, fresh whenever possible, to make a few of the tinctures that I need. I always purchase these herbs certified organically grown. If I can't wild harvest an herb myself or get it from a certified organically grown source, I don't use it. I never purchase commercially wild harvested herbs.

That being said, due to the increasing popularity of herbs and herbalism coupled with our unsustainable population growth, there may come a time when it is no longer possible for me to continue wild harvesting the herbs that I use. The wild populations of herbs simply won't be able to handle it. At that point I will grow as many as I can and purchase the rest. But I'll still go out there and continue to deepen my relationship with the wild herbs and the lands where they live.

There is no doubt that there are a few wild herbs that can handle some level of commercial wild harvesting at this point. However, there aren't many and a lot of them are not well known or commonly used. The criteria that would need to be met for an herb to fall into this category are: it must be very plentiful and adaptable, more or less invasive by nature; it must prefer to live in the kinds of habitats that humans create when we change the landscape; it must be able to be harvested without negatively impacting the ecosystem where it lives. In North America, most of the herbs that fall into this category are Eurasian plants that have naturalized here, such as common dandelion (Taraxacum officinale), burdock (Arctium spp.) and red clover (Trifolium pratense). In my region, the only native species that I would include are a few species of asters (Symphyotrichum spp.) and goldenrods (Solidago spp.). Obviously, it will be different in different regions. Another possibility is using the parts of some commercially harvested tree species that are discarded during the harvesting process, such as the leaves and young twigs of conifers like white pine (Pinus strobus).

Canada goldenrod (Solidago canadensis) is one of the few native Ontario herbs
that could be wild harvested commercially to some degree.

One of the reasons that people like wild harvested herbs is because there is a belief that their medicinal properties are superior to those of cultivated herbs, even if they are organically cultivated. For the most part this is true, but it doesn't have to be! Wild harvested herbs have a lot more strength and vitality than cultivated herbs even though cultivated herbs may sometimes look better. This is partly because cultivated herbs are often grown in conditions (soil type, moisture, amount of direct sunlight, monoculture, etc.) that are not typical of their natural habitat. However, the main reason is because cultivated plants are pampered. We all need a certain amount of stress to maintain a decent level of health and vitality. Plants are no exception. Too much stress can weaken them, but so can too little stress. For instance, a certain amount of drought stress is good for most plants. How much depends on the species. Watering them every time the soil gets a bit dry usually isn't a good idea. However, letting them dry out completely isn't either. Also, every organism needs some competition. This can be accomplished by careful companion planting. It is also a good idea to allow some "weeds" to grow, as long as they aren't allowed to get the upper hand by crowding out the herbs we are growing, above the ground or below it. Most "weeds" are useful anyway, either as medicines or foods.

So that is my rant about chaga and the ethics of wild harvesting. Once more, for more information I recommend reading my earlier post Wild Harvesting Herbs. In the mean time, the chaga is rapidly disappearing from the more accessible areas of southern and central Ontario. Although chaga is a great medicine when used correctly and with respect, I strongly recommend considering other medicinal fungi that are available from organically grown sources such as lacquered polypore or reishi (Ganoderma lucidum), hen-of-the-woods or maitake (Grifola frondosa), or oyster mushroom (Pleurotus ostreatus).

Applying a Poultice

This post is an tangent from my series on Healing Bone Fractures. In that series I have mentioned applying herbal poultices to my leg. I had considered including more details about applying a poultice in one of those posts but decided to do it separately so I can provide more details. I would like to thank my friend Elyse Portal who took some great photos while I was applying a poultice to my leg last weekend.

For the most part, a poultice is the most potent method of application of herbs to a localized area. This is because as the constituents of the herbs are absorbed into our tissues through the layer of moisture covering our skin, they are immediately replaced by more constituents from the herbs that diffuse into the layer of water. Also, the concentration of constituents is very high because the ratio of herb to liquid is very high. We are using a lot of herb and very little water.

We usually use dried herbs, but I often apply what I call a "survival poultice" if I get some kind of injury or bite when I'm wandering around in the fields and woods. In these circumstances I will find one or a few good healing herbs in my immediate area, chew them up and apply them where needed. I used to do this for my kids when they were small and we were on a hike or camping trip. You don't need to worry too much about bacteria in saliva because the antimicrobial properties of the herbs are very concentrated when applied this way and will take care of any risk of infection.

Here is the bowl of dried herbs I'm using for this particular poultice.

When using dried herbs, they should be coarsely ground. I usually rub them between my palms or use a mortar and pestle. We apply just enough boiled water to moisten them but so that they are not runny.

The herbs after moistening them with boiled water.

The purpose of the poultice I am preparing is to help heal the incisions from my surgery and to penetrate deeper into my leg to help heal my broken tibia (shinbone) as well. This poultice consists of 1 part common comfrey leaf (Symphytum officinale), 1 part stinging nettle leaf (Urtica dioica), 1 part purple loosestrife herb (Lythrum salicaria), 1 part pot marigold petals (Calendula officinalis), 1 part Canada goldenrod herb (Solidago canadensis) and 1/2 part whole flax seed (Linum usitatissimum). It is essential that a poultice is very mucilaginous. Comfrey is one of the few herbs that is mucilaginous enough that it doesn't require the addition of a more mucilaginous herb. However, since comfrey is only making up 20% of this formulation, it is necessary to add something to make it more slimy. My preference is to use a small amount of whole flax seed whenever I prepare a poultice. It will add the extra mucilage that we need and has important healing properties of its own. Never use ground flax seed. We just want the mucilage. We don't want to release the oil.

Getting ready to apply the poultice. At this point I had been poulticing the smaller incision on the right twice per day

for two weeks and the larger incision on the left for one week. There is clearly a difference between the two.

When applying a poultice I always put some gauze between the poultice and the skin. This serves two purposes: firstly, it ensures that small particles of herbs can't get into an open wound; secondly, it allows the poultice to be easily lifted off when finished without having to wipe bits of herb off the skin. This is important because when we remove the poultice we want any remaining herb infused liquid to dry on the skin. We use the minimum amount of layers of gauze to prevent bits of herb from getting through. The number of layers will depend on the thickness of the gauze.

Laying the gauze in preparation for the poultice.

When we apply the poultice we must completely cover an area a bit larger than the area we are working on with the moistened herbs and press down on them so that there is good contact with the skin. I usually apply it with a spoon and use the spoon to press the herbs once they are applied.

Beginning to apply the poultice...

...and finishing it off.

Under normal circumstances our skin is water-proof. In order to get the constituents of the herbs in our poultice to penetrate through our skin our skin must be hydrated to eliminate its water-proof characteristics. To accomplish this it is necessary for the entire area where we wish to apply the poultice to remain moist. We can't allow the skin to breathe. To accelerate this process it is also necessary that the poultice be applied as hot as we can tolerate and remain warm for the duration of the application. This process also takes time. The longer the poultice is in contact with our skin, the more hydrated our skin becomes and the better the penetration. I usually recommend a minimum of 30 minutes, but an hour or more is sometimes necessary, depending on the severity of the condition being treated. To facilitate the hydration of our skin it is best to wrap the poultice in plastic so that our skin remains in complete contact with herb infused liquid from our poultice and isn't able to breathe (no contact with air). Most types of plastic wrap are made of polyethylene which isn't known to leach any toxic chemicals. After wrapping the poultice I recommend pushing down on it once more to make sure there is good contact with the skin and no air spaces between the plastic and the herbs.

The poultice wrapped in plastic.

This whole process must be done as quickly as possible so that the herbs are still hot. Once the poultice has been wrapped in plastic it is necessary to cover it with a towel or something similar to help insulate it to keep it warm. If is going to be applied for a long period of time it may be necessary to apply a hot compress over the plastic. A cloth soaked in hot water that has been wrung out so that it isn't dripping will do. The cloth can be reheated periodically when it cools down. If the area where we need to apply the poultice isn't too large, a hot water bottle will also work and is more convenient than using a compress.

Covering the poultice with a couple of layers of towel.

Once we are done we can remove the poultice. For my leg, I have been applying a poultice for 45-60 minutes twice per day. When we use gauze the whole thing will lift off really easy.

The poultice has been uncovered and is ready to be removed.

When we remove the poultice the skin will be moist with herb infused liquid. We don't want to wipe this off. Let it dry completely before covering the area.

After removing the poultice we let the remaining liquid completely dry on the skin.

Notice the larger droplets of herb infused water.

Once the remaining herb infused water has dried completely the process is complete. We can bandage the area, if necessary, or cover it in some other way. We can also apply an ointment or liniment to the area, if appropriate, to further assist the healing process.

Which herbs we use, how often and how long we apply a poultice will depend on the situation, but the basic elements of applying a poultice will always be the same.

Cultivated Vs. Wild Harvested Herbs

Here comes another one of the "background" posts that I mentioned. I took some photos when Monika and I were harvesting on Sunday and am going to do a post on harvesting blue vervain (Verbena hastata) soon, but I have a couple more background posts to do first. I'm doing a series of posts this week to kick this thing off. After that it will have to find its place in my schedule and the posts will be less frequent.

As I mentioned previously, the way I do herbalism necessitates that I make all of my own medicines. I also have a preference for using tinctures made from fresh herbs. That means that the group of herbs I work with are those that are native, naturalized or can be grown in northeastern North America, southern Ontario more specifically.

I don't grow many herbs. I've always primarily wild harvested them. When I tried growing them it was not very successful. I spend so much time wild harvesting that my garden tended to be neglected. I anticipated that and only planted hardy perennials, but over time my garden became over-run with plants such as goldenrods (Solidago spp.), asters (Symphyotrichum spp.) and tansy (Tanacetum vulgare). Although I planted hardy species, most of them couldn't handle being shaded by these taller plants. I just don't have much time for "weeding" and don't use the roots or rhizomes of these species, so digging them up isn't useful for me.

As a compromise, I have introduced some native and naturalized species onto the land where I live. In some cases they don't proliferate to a degree that I will be able to harvest them here, but they are good friends and I like having them around. In other cases plants that I have introduced have expanded quite a bit, some of them enough that I can harvest part or all of what I need right here. The key is to understand the kind of soil, moisture and light conditions that each species prefers. This is something that is easily learned by spending a lot of time with them in places where they grow naturally.

Musk mallow (Malva moschata) is one of the plants that I
introduced and now grows wild on my property.

Another thing that I do is pay close attention to what is growing on my lawn. Knowing how to recognize plants when they are very small and being attentive when I am mowing allows me to mow around the species of herbs that I use when they arrive here. By selectively mowing around these species it gives them a competitive advantage over the grass and other plants by allowing them to grow to full size and reproduce. Some of them multiply very fast. I have about 3/4 acre of mowed space around my house with many trees and shrubs, so there is a variety of amounts of light and moisture available. This is important if we want to encourage a large number of species to grow. It's amazing how many species arrive on their own. After mowing my lawn this way for about 12 years, there are now 96 species of plants that weren't there before I started mowing in this way. Of these, 22 were introduced. About half of the introduced species escaped out of my garden, whereas I introduced the other half directly onto my lawn. There are 38 species that arrived naturally, and 10 that I introduced that are either plants that I don't use, or herbs that I use but are not growing in sufficient quantity for me to harvest them. On the other hand, there are 36 species that arrived naturally and 12 that I introduced that are growing in sufficient quantity that I can harvest directly from my lawn some or all of what I need of each of these species to prepare tinctures for my clinic from year to year. Regardless of how plentiful they are, I use all of them as teaching tools as I run my classes and clinics out of my house. My lawn is my herb garden!

The view from my front door. Things are not as lush as

they should be in early July. We've had the driest

and hottest spring that I can remember.

Some of the herbs that are now growing

wild in my back yard.

Many herbalists, including myself, recognize the superiority of wild over cultivated herbs. However, it doesn't have to be that way. Assuming that herbs are grown organically (I'm not going to get into the numerous issues associated with the use of commercially grown herbs), there are essentially four reasons why cultivated herbs are inferior:

1. Cultivated herbs often aren't grown in conditions that each species prefers. Again this includes soil type and levels of moisture and light.
2. Cultivated herbs are grown in monoculture on bare soil. Plants need to be interspersed with other species. This reduces diseases and insect damage, and provides a bit of competition. Bare soil doesn't exist in nature except after a major disturbance. It increases erosion and loss of moisture from the soil and is an invitation for any plant that likes disturbed soil to grow there.
3. Cultivated herbs are babied. They are watered too much and "weeded" excessively. This may make them grow more lush and faster, but it doesn't make them stronger. In order to be strong and healthy, all living things need to struggle. When life is too easy they get weak. If there is a prolonged dry period, it's OK to water them. Too much stress will also weaken them. But we don't want to overdo it. We also want to take into account the amount of moisture that each plant requires. If it is a wetland plant and we can't plant it by a wetland, it will need more watering and probably some shade. Similarly, plants need competition. There are no "weeds", only opportunistic plants that take advantage when we screw up the balance of things or create habitats that they like. It's a good idea to keep out the invasive species or any plants that are large and will overshadow the herbs that we are growing. We also don't want to let our herbs get too overcrowded. Most of the "weed" species are medicinal anyway. We can harvest them as well. We just need to make sure that they aren't too competitive or plants that when harvested will result in too much disturbance of the herbs we are growing.
4. Cultivated herbs are usually harvested incorrectly. They harvest too much of the plant at the wrong time of day and the wrong stage in the plants life-cycle. This is because the scale necessitates it, both in terms of when and how much of the plant is harvested. They need to harvest herbs in a way that results in the greatest yield, and when growing a very large number of plants that need to be harvested, it isn't possible to be very picky about when they are harvested.

If we take these things into consideration when we grow herbs (or vegetables), the herbs we grow will approximate the level of potency and vitality of wild harvested plants. There's also the option of wild gardening: introducing plants where we live (as long as they are not invasive species). Once established, we can encourage them along in various ways.

This discussion is very important to the issue of wild harvesting. Although wild harvesting is a very healing and empowering activity, as more people become interested in it there is a very great potential that we can seriously impact wild populations in a negative way. This can happen even if everyone does their best to wild harvest in an ethical way. It is inevitable because there are just too many people living on this planet. So learning from the wild plants what their needs are and applying it by wild gardening or organic gardening that takes into account the specific needs of each species is a very important alternative to wild harvesting. It will become even more important as more people become interested in making their own medicines.
