in cultivation and harvesting practices. At that time, he asked me and a friend, Betty Richardson, to start to grow medicinal herbs in the United Kingdom. The aim was for us to build up knowledge about how to grow the herbs at lower altitude and in the softer growing conditions in Europe. In time, the European-sourced herbs could help to supply Tibetan medicinal practitioners based in the West. He specified that this initial herb growing should take place in Somerset, although at the time I was living in Dorset and Betty was living in Gloucestershire. We thought it was odd, wondering whether he was mistaken, since the counties are adjacent. A few years later Betty had moved her growing operations to Spain, and my family and I found ourselves unexpectedly having to move away from Dorset. We ended up in Somerset.
I now grow some Tibetan medicinal plants in my garden. Each year of growing adds to my knowledge about how to care for and propagate these herbs in the West. My efforts are especially focused on plants that are scarce, and one, Himalayan Burdock (Saussurea lappa), is officially extinct in the wild. Saussurea lappa, also known as Costus (‘Ruta’ in Tibetan), is gathered for its root, which is a warming bitter, particularly valuable for people with a nervous disposition who are suffering with digestive weakness. It is a very popular medicine and is used in a great many important traditional formulae. In consequence, it is in great demand. Although officially extinct in the wild according to the Convention on International Trade in Endangered Species of Wild Fauna and Flora [CITES], there may possibly be some remote populations still existing at high altitudes, accessible only to those who know the locality. It does worry me that wild harvesting may still be continuing, as there is such a strong demand for these plants. The way forward for this plant is definitely to encourage the availability of good-quality cultivated stock, and hopefully in time wild populations may begin to recover.
It is definitely food for thought to be growing and harvesting seeds from a plant that is so precious and scarce. My trips to Tibet and this small-scale conservation work has really brought home to me the reality of how our demand for medicinal herbs affects the habitats and plant populations far from where we live. Many plants used by medical herbalists are at risk in the wild. Take Golden Seal (Hydrastis canadensis), Slippery Elm (Ulmus fulva), Blue Cohosh (Caulophylum thalictroides), Ginseng (Panax ginseng and Panax quinquefolius), Beth Root (Trillium erectum) and Black Cohosh (Actaea racemosa or Cimicifuga racemosa, as it was formerly known), for example. It is not all doom and gloom, though: great conservation work and awareness-raising is being done by United Plant Savers and other conservation bodies. Growers are stepping up to the challenge and growing these endangered and scarce species, so that there are sustainable sources for practitioners to buy stock from. It is also inspiring to see the work being done by the Sustainable Herbs Program. It would seem that plants do, in fact, have people speaking up for them.
As herbalists, we source and work with a wide range of medicinal plants other than those that are endangered. Some will be relatively common, others will be scarcer. Certification schemes can be a helpful guide to how herbs have been produced, but availability of certified stock may be limited, and we cannot know everything about how they have been produced and the social and environmental impact that has been created. Ultimately, the best way to ensure that we take care of the environment while sourcing our herbs is to form relationships with local growers or to start to grow them or gather them ourselves. When we do this, we know that our actions will not have contributed to the destruction of a habitat or to the depletion of a scarce plant population. The herbs will not have been shipped long distances using fossil fuels. Their production will not have contributed to social inequality or exploitation.
We may not be able to grow or gather all that we need, but each herb that we can source in a self-sufficient manner will result in a significant positive contribution to the environment, along with many other benefits.

Quality of plant medicines
When I first started growing and gathering my own herbs, I was motivated by factors other than quality. I had come to herbal medicine through my love of herbs, and it was only natural that I should wish to spend time with them. By growing and gathering the herbs that I was using to treat patients, I could build a real connection with them and get to know them much more deeply than if I had been relying on bought-in dried herbs. At first, I gathered only relatively few herbs. Each year, as I came to know my local area better, I was able to increase the number of species that I could collect. In the early years, though, I relied more on a mixture of bought-in herbs combined with those that I had grown or gathered myself. In those days, I was not as proficient as I am now at estimating the quantity of each herb that I would need during the year ahead. I would often start the season with my own herbs and then buy in replacement stock when it was needed. As a result, I had numerous opportunities to compare my own home-grown and wild-harvested herbs with those that were provided by herbal wholesalers. I immediately realized that the quality of my own herbs seemed markedly better than those that I was buying in.
Even though large-scale herbal suppliers make every effort to source the highest possible quality herbs for sale, they would be the first to agree that batches arriving at the warehouse vary, in both medicinal and keeping qualities. In order to safeguard quality and safety, suppliers have to put into place sophisticated, costly, time-consuming procedures to assess each batch of herbs that they purchase. It is worth noting that the certification schemes that were outlined in the previous chapter do not guarantee the quality of herbs. They simply give assurances about how they have been grown and harvested. For example, we touched on the issues surrounding wild harvesting and the efforts to address social inequalities in traditional gathering populations by FairWild certification. Very impoverished gatherers, paid by the weight of herb collected, may be tempted to adulterate their harvest with rocks or soil in an effort to earn enough to feed their families. This is described officially as ‘economic adulteration’, in recognition of the pressures that arise when growers and gatherers do not feel that they are getting a fair price for what they are supplying. Likewise, wildcrafters gathering herbs in less abundant years may be under pressure to include plant material that is faded, past its best or infected by insect or fungal pathogens. They may even be tempted to gather similar-looking plants that are not related to the target species. We know that we should not gather herbs growing by the side of busy, dusty roads, in cemeteries or growing in waste water from settlements, but wholesale gatherers may make the decision to overlook such restrictions on the basis of economic necessity. Problems with quality are not restricted to wild-harvested herbs. Cultivated herbs can also be subject to unexpected inclusions. Although it has never happened to me, herbal colleagues have reported the presence of soil, cigarette butts, plastic ties, and even, perhaps most disturbingly, animal faeces in some batches of cultivated herbs that they had bought in. Needless to say, in all cases those batches were immediately returned to the supplier with a complaint.
In order to safeguard quality standards, many wholesale suppliers are investing huge sums of money in complying with ‘Good Manufacturing Practice’ (GMP). Batches of herbs are tested for adulteration with foreign objects and for adulteration with other species of plants. They may be tested for pesticide and heavy metal contamination, as well as the presence of fungi and insects. Sometimes shipments are rejected outright if they are below the required standard, and at other times remedial action can be taken. Remedial action may include sieving out physical adulterants such as soil and rocks and irradiating or freezing the herbs to kill insects and larvae. In the latter case the dead insects and larvae remain within the batch of herbs. I find it rather disconcerting to think that there is a certain level of insect larvae that is considered officially acceptable to be present in GMP-compliant herbs.
It is perhaps surprising to find that GMP does not actually require testing for the level of therapeutic compounds in herbs. As long as a herb is what is says on the bale or sack and it passes safety and adulteration checks, it is officially good to go and can be
