New York Attorney General Warns Walmart, Target, Walgreens, and GNC to Stop the Sale of Echinacea, Ginseng, & Other Herbs

February 2, 2015

DNA testing commissioned by New York State Attorney General Eric T. Schneiderman has found that store brands of popular herbal supplements sold at major chain retailers often do not contain the advertised herb. In fact, just 21 percent of the herbal products tested contained DNA from the herb promised on the label. 79 percent either had no DNA from the advertised herb or had DNA evidence of material from other plants, such as rice, beans, pine, and other fillers or contaminants.

The New York Attorney General's office tested echinacea, ginseng, ginkgo biloba, St. John’s wort, and other popular store-brand supplements purchased from GNC, Target, Walgreens, and Walmart throughout the state.

None of Walmart's Spring Valley line of Echinacea contained DNA evidence of the herb, according to the Attorney General's office.

"Consumers already had ample reason to doubt most of the claims made by herbal supplement manufacturers, who have precious little scientific evidence indicating these herbs’ effectiveness in the first place," said CSPI senior nutritionist David Schardt. "But when the advertised herbs aren't even in many of the pills, it's a sign that this poorly regulated industry is in desperate need of reform. Until then, and perhaps even after then, consumers should stop wasting their money in the herbal supplements aisle."

The New York Attorney General's office sent cease and desist letters calling on the four retailers to stop selling the tested supplements and to provide information about their processing methods and quality control procedures.

"Attorney General Schneiderman has done what federal regulators should have done a long time ago," said Schardt.

DNA testing conducted in recent years by various researchers found similar problems with black cohosh, saw palmetto, ginkgo biloba, and other herbal supplements.
