Store-brand herbal supplements fail DNA test in New York investigation
Testing in New York state on hundreds of bottles of store-brand supplements finds four out five contain none of the herbs on the label

Bottles of Walmart-brand echinacea, an herb said to ward off colds, were found to contain no echinacea at all.
Bottles of St John's wort marketed under the GNC brand had elements of rice, garlic and a tropical houseplant, but not a trace of the herb.
In fact, DNA testing on hundreds of bottles of store-brand herbal supplements sold in New York state as treatments for everything from memory loss to prostate trouble found that four out of five contained none of the herbs on the label.
Instead, they were packed with cheap fillers such as wheat, rice, beans or houseplants.
Based on the testing commissioned by his office, New York Attorney General Eric Schneiderman has sent letters to the four major US store chains involved - GNC, Target, Walmart and Walgreens - demanding that they immediately stop selling adulterated or wrongly labelled dietary supplements.
Schneiderman said the supplements pose serious risks. People who have allergies or are taking certain medications can suffer dangerous reactions from herbal concoctions that contain substances not listed on the label, he said.
