New York Attorney General targets herbal marketers. New York Attorney General Eric T. Schneiderman has sent letters ordering GNC, Target, Walmart, and Walgreens to stop selling store-brand herbal products that could not be verified to contain the labeled substance(s), or which were found to contain ingredients not listed on their labels. The products included echinacea, ginseng, and St. John's wort. The letters were sent because DNA tests performed as part of the Attorney General's ongoing investigation found that only 21% of the products contained ingredients listed on their labels. Quackwatch has more details plus links to the warning letters. The investigation was triggered by a New York Times report about a Canadian study which found widespread discrepancies between the ingredients listed on the labels of 44 popular products and those found in the products.
