“I tell cancer patients they shouldconsult a qualified herbalist,” says Gordon.But he warns against over-thecounterginseng supplements. One recentstudy by ConsumerLab.com, anindependent organization that testsherbal and nutritional supplements,found that only 9 of 22 internationalginseng supplements met its criteria forquality and purity; some even containeddangerous amounts of lead andother heavy metals. “The quality andreliability of ginseng supplements is amajor problem,” says Gordon, whochairs the White House Commissionon Complementary and AlternativeMedicine Policy. “We’re interested inmaking sure that what’s in the bottle ison the bottle.”In the United States, ginseng is secondonly to gingko as the most popularherbal supplement. It has made its wayinto a number of products, from teasand chewing gum to tinctures, snackchips and “smart” drinks, which arenutrient-enriched drinks marketed tocounter stress. Health claims for ginsengalso vary widely—and arouse suspicionfrom regulators and consumeradvocators. Wyeth Consumer Healthcare,one of the largest producers ofhealth care products in the world,claims that its Centrum Herbals Ginsengsupplement “helps maintain staminaand energy levels and may enhancephysical performance.” Marketers ofGinsana, the most popular ginseng supplement,boast that the product will“enhance physical endurance” and “improvesoxygen utilization.” Other claimsinclude increasing sexual potency, reducingproblems associated with menopauseand even improving memory.
“What is most striking about ginsengis the amount of misinformation in adsand on packages,” says nutritionistDavid Schardt at the Center for Sciencein the Public Interest (CSPI). “Panax ginseng,the most commonly available type,does not boost energy levels, mood, ormemory and doesn’t reduce stress.”
After reviewing studies over the pasttwo decades, the CSPI asked the Foodand Drug Administration three yearsago to halt phony claims. During thepast two years, the FDA has sent lettersto about half a dozen manufacturers,ordering them to limit product healthclaims due to the lack of evidence tosupport them.
Ginseng’s effectiveness, or its lackthereof, will likely not be definitivelydetermined anytime soon, partly becausethe traditional underwriters oflarge-scale clinical studies—pharmaceuticalcompanies—have little incentive totest an ancient nostrum that is alreadywidely sold and largely unpatentable. Inthe meantime, ginseng’s most therapeuticeffect may be in breathing economiclife into poor, rural communities in thesouthern Appalachian mountains.
“Ginseng is an economic answer forWest Virginia, where things like coalmining are on the way out,” says FredHays. “A small landowner can sell hislumber and wait a generation for it togrow back,” he says, or plant Christmastrees. “But in the same little square thatyou can grow one little Christmas treein eight years, you could grow $3,000 to$4,000 worth of ginseng.”
Which would make ginseng, cure-allor not, worth rooting for.
