On November 3, 2013 the New York Times published an article, "Herbal Supplements Are Often Not What They Seem."
The article reviewed a study that used DNA testing and found that about 1/3rd of the 44 herbal supplements that were tests were contaminated or did not contain what the labels claimed they contained.
In checking the validity of this article and the study that was the basis for the negative herb study, I asked Michael McGuffin, the President of the American Herbal Products Association (APHA), a person that has been known for many years to be an excellent source of science-based information about herbal products
McGuffin said, "The cited study contains significant flaws and represents DNA analysis far beyond its actual capability to identify ingredients in herbal products. I have attached an article that appeared in our newsletter in February to respond.
The article that appeared in the AHPA newsletter can be viewed by clicking here.
We have recently sen New York Attorney General, Eric Schneiderman attempt to use this poorly constructed herbal hit-piece to attack herbal products in Walgreen's, GNC, Target and Walmart.
Fortunately, such authorative organizations as the Council for Responsible Nutrition are fighting Schneiderman's blunder with solid data.
