The Plants Themselves
Best-Quality Herbs
The best herbs to use for medicinal or culinary purposes are those
collected from the wild, in areas where the plant is found growing naturally,
away from contaminants. Unfortunately, the colossal increase in demand
for herbs
has meant that some of the time, they are being collected from unsuitable
wild sources, such as roadside verges, and that wild sources are being
over plundered.
The huge increase in demand and a belated desire for quality have led
to an upsurge in organically grown herbs. Hundreds upon hundreds of
acres of herbs are now being grown in parts of Europe (in particular
Germany) and worldwide. Dr. John Christopher was a pioneer on the
subject of organics. He insisted upon organic and wild-crafted herbs for
medicinal purposes. So much of illness today is based upon allergies to
pollution and toxicity levels that we don’t want to add to it. Botanical
herbalists know that plants growing in the wild will produce more
“primitive” and original chemistry as they fi ght to survive selective
pressures, resulting in some aggressive chemical variations. For instance,
with the herb cascara sagrada (Rhamnus purshiana), which is heavily
harvested in the temperate rain forests of North America, demand
instigated its cultivation in an area where it grows wild! This effort turned
out to be unsuccessful, as the laxative effect of the cultivated variety was
shown to be much less potent than that of the wild- harvested bark.
However, in April 2002, the U.S. Fish and Wildlife Service listed cascara
sagrada in CITES (Convention in Trade in Endangered Species) in their
Appendix II category. This category houses species that are not threatened
with extinction but may become so if international trade is not controlled.
The monoculture of herbs will increase over time and, in the long term,
could alter the chemistry of plants and eventually may even forever
change them genetically. I have no personal answer to this problem,
because we have a great need for herbs, we have diminished land, and we
do not want to defoliate our wild areas. Many native U.S. medicinal plant
species are being considered for inclusion into CITES Appendix III (a
category which requires the cooperation of other countries to prevent
unsustainable or illegal exploitation). These plants include black cohosh,
echinacea, and osha (Ligusticum porteri).
The question of good-quality herbs was always a vital one to herbalist
