chemical experiments

GMP Herbal Products and FDA notified consumers and healthcare professionals of a recall of Pai You Guo, a weight loss dietary supplement, due to the presence of undeclared drug ingredients.

FDA lab analyses of dietary supplements were found to contain undeclared sibutramine, an FDA-approved drug used as an appetite suppressant for weight loss; and phenolphthalein, a solution used in chemical experiments and a suspected cancer-causing agent that is not approved for marketing in the United States.
