Nutraingredients-USA.com reports that a new study reports that one-third of black cohosh products tested were not genuine but contained substituted products. In response, the American Herbal Products Association (AHPA) issued a statement reminding manufacturers that they have a responsibility to know what they are selling and to take adequate steps to ensure that the ingredients in their products match the product labels.
