"The
World Health Organization notes that of 119 plant-derived
pharmaceutical medicines, about 74 per cent were
used in modern medicine in ways that correlated
directly with their traditional uses as plant
medicines by native cultures."
Herbal
medicine is the most ancient form of health care known to humankind.
Herbs have been used in all cultures throughout history. Extensive
scientific documentation now exists concerning their use for health
conditions, including premenstrual syndrome, indigestion, insomnia,
heart disease, cancer and HIV.
Herbs
have always been integral to the practice of medicine. The word
drug comes from the old Dutch word drogge meaning 'to dry',
as pharmacists, physicians and ancient healers often dried plants
to use as medicines. Today approximately 25 per cent of all prescription
drugs are still derived from trees, shrubs, or herbs. Some are made
from plant extracts; others are synthesized to mimic a natural plant
compound.
Yet,
for the most part, modern medicine has veered from the use of pure
herbs in its treatment of disease and other health disorders. One
of the reasons for this is economic. Herbs, by their very nature,
cannot be patented. Since herbs cannot be patented and drug companies
cannot hold the exclusive right to sell a particular herb, they
are not motivated to invest any money in that herb's testing or
promotion. The collection and preparation of herbal medicine cannot
be as easily controlled as the manufacture of synthetic drugs, making
its profits less dependable. In addition, many of these medicinal
plants grow only in the Amazonian rain forest or other politically
and economically unstable places, which also affects the supply
of the herb. Most importantly, the demand for herbal medicine has
decreased in the United States because Americans have been conditioned
to rely on synthetic, commercial drugs to provide quick relief,
regardless of side-effects.
Yet,
the current viewpoint seems to be changing. "The revival of
interest in herbal medicine is a worldwide phenomenon," says
Mark Blumenthal, Executive Director of the American Botanical Council.
This renaissance is due to the growing concern of the general public
about the side-effects of pharmaceutical drugs, the impersonal and
often demeaning experience of modern health care practices, as well
as a renewed recognition of the unique medicinal value of herbal
medicine.
"The
scope of herbal medicine ranges from mild-acting plant medicines
such as chamomile and peppermint, to very potent ones such as chamomile
and peppermint, to very potent ones such as foxglove (from which
the drug digitalis is derived). In between these two poles lies
a wide spectrum of plant medicine with significant medical applications,"
says Donald Brown, of Bastyr College, in Seattle, Washington, and
an educator in herbal medicine. "One need only go to the United
States Pharmacopoeia to see the central role that plant medicine
has played in American medicine."
