GENEVA The World Health Organization issued guidelines on Tuesday for ensuring the safety and efficacy of the multibillion dollar herbal medicines market amid reports that some products are tainted with toxic substances.
The guidelines, intended for national regulatory bodies, lay out the best techniques for growing and harvesting medicinal plants used for various ailments or weight loss, as well as the clear labeling of the contents of any product.
Herbal medicines represent an estimated US$60 billion a year global market, some 20 percent of the overall drug market, according to the U.N. agency. Yet only China, Japan, and the European Union have regulations for medicinal plants.
"It is not a binding guideline for any country, but it is a model or sort of checklist which they can use to make their own national regulations," Hans Hogerzeil, acting director of WHO's essential drugs and medicines department, told a news briefing.
The U.S. Food and Drug Administration last December issued a consumer alert on the safety of dietary supplements containing ephedra, also called Ma huang, a natural substance. The adrenalinelike stimulant, used for weight loss or to boost sports performance, can have dangerous effects on the heart.
In Africa, up to 80 percent of the population depends on traditional medicine for primary health care. In China, herbal preparations account for up to 50 percent of total consumption.
In Europe, North America, and other industrialized areas, more than 50 percent report using complementary or alternative medicine at least once, according to WHO.
"There is also an enormous industry now, where huge amounts of leaves and traditional medicines are being shipped from various exporting countries China, India, Pakistan to many other countries. Somebody has to regulate that, at least their safety," Hogerzeil said.
