19. Herbal remedies are facing stress
Herbal shampoo and medicine makers could learn something from American Indians
about harvesting medicinal and aromatic plants without endangering some
vanishing and valuable species.
American Indians gathering plants for herbal remedies take only those they
need, and utter songs and chants lamenting the sacrifice and affirming that the
plants are being harvested to relieve suffering, said Tis Mal Crow of
Speedwell, Tenn., a Western Band Cherokee healer.
“From any one area we limit the amount taken. They are taken only at certain
times of year,” Crow aid. That’s in contrast with some commercial harvesters
who, he said, “go in there with bulldozers and clear off whole hillsides.”
Crow is one of 10 members of a Native American Elder Circle who take part in a
U.S. Fish and Wildlife Service Medicinal Plant Working Group discussing ways to
protect threatened plants. The group also includes representatives from
industry, government, academia and env ronmental organizations.
“Plants that our grandfathers’ grandfathers respected and protected for future
generations are no longer available to us, “ said Crow, author of “Native
Plants, Native Healing”. He spoke recently at a symposium the working group
helped organize on Industrial Leadership for the Preservation of Medicinal and
Aromatic Plants.
North American environments from alpine tundra to prairie grasslands, coastal
salt marshes and tropical rain forests have 20,000 plant species, the working
group reported in December 2000. At least 175 species are marketed for use in
over-the-counter remedies and supplements in the $3 billion U.S. medicinal herb
market. Many plants are collected from the wild in large quantities. For
example, about 65 million goIdenseal plants and 34 million ginseng plants a
year have been harvested from eastern U.S. forests in recent years, according
to the report.
The two-day symposium included pharmaceutical, cosmetic, vitamin and herbal
product makers, academics, farmers and government representatives. “We are
interested in creating partnerships with as diverse a group as possible and
bringing together as many interest groups as possible,” said Julie Lyke, a U.S.
Fish and Wildlife Service bioloist.
Some plants are plentiful enough to harvest without concern, said Michael
McGuffin, president of the American Herbal Products Association, a Silver
Spring, Md., trade group. “Saw palmetto is harvested in the wild, but it’s
estimated that there are 4 million acres of it," McGuffin said. “Black
cohosh is one we are concerned about. The root is the part used. End of plant.”
One presentation involved some successful efforts to cultivate black cohosh, an
eight-foot perennial with stems and roots used to treat menstrual and digestive
problems and rheumatism.
But plants such as goldenseal root, often used in combination with vitamin C;
American ginseng, marketed as an energizer and immune stimulant; and echinacea,
also sold as an immune stimulant, are considered at risk of extinction, Crow
and McGuffin said.
Herbal product manufacturers’ demand for plants can end up preserving natural
habitats, such as rain forests, said Dominique N. Conseil, president of Aveda,
a maker of plant-based shampoos, cleansers and cosmetics.
Conseil said that can be the result if companies show local people how to
harvest herbal products that are more profitable than logging or clearing the
land for other uses.
“Communities need to have a source of revenue. It’s about developing a source
of revenue that preserves the wild,” Conseil said. “If they can make a living
from the environment without destroying it, when that works, it’s ideal.”
For some plants, the effort comes too late. Of 200 species discovered by
Meriwether Lewis and William Clark on their expedition of 1803 through 1806, it
isn’t known if 30 percent still exist, said Ara DerMarderosian, a professor of
pharmacognosy, the study of drugs from natural sources, at the University of
the Sciences in Philadelphia.
It is therefore a primary goal to catalog American plants, DerMarderosian
noted. “We hope they are still there. There are a lot of places you’ll go and
find a parking lot.”
