Bar coding of DNA to Identify DNA of Herbals not completely accurate

A few months ago the New York State Attorney General (AG) drew news headlines because his office announced many herbal supplements sold in retail stores are nothing more than cheap fillers like powdered rice or house plants! The AG used a new DNA bar coding test which is not the standard way to test natural molecules in dietary supplements. Researchers recently reviewed the accuracy of DNA bar coding, which produced mixed results. Researchers gave a thumbs-down to DNA bar coding as a sole means of identifying molecules but instead of dismissing it outright, said it would be used with other test methods.
