The New York State attorney general’s office accused four major retailers on Monday of selling fraudulent and potentially dangerous herbal supplements and demanded that they remove the products from their shelves.
The authorities said they had conducted tests on top-selling store brands of herbal supplements at four national retailers — GNC, Target, Walgreens and Walmart — and found that four out of five of the products did not contain any of the herbs on their labels. The tests showed that pills labeled medicinal herbs often contained little more than cheap fillers like powdered rice, asparagus and houseplants, and in some cases substances that could be dangerous to those with allergies.
The investigation came as a welcome surprise to health experts who have long complained about the quality and safety of dietary supplements, which are exempt from the strict regulatory oversight applied to prescription drugs.
The Food and Drug Administration has targeted individual supplements found to contain dangerous ingredients. But the announcement Monday was the first time that a law enforcement agency had threatened the biggest retail and drugstore chains with legal action for selling what it said were deliberately misleading herbal products.

Dr. Cohen at Harvard said that the attorney general’s test results were so extreme that he found them hard to accept. He said it was possible that the tests had failed to detect some plants even when they were present because the manufacturing process had destroyed their DNA.
But that does not explain why the tests found so many supplements with no DNA from the herbs on their labels but plenty of DNA from unlisted ingredients, said Marty Mack, an executive deputy attorney general in New York. “The absence of DNA does not explain the high percentage of contaminants found in these products,” he said. “The burden is now with the industry to prove what is in these supplements.”
