The FDA has tested multiple Zi Xiu Tang Bee Pollen products from various distributors in the United States. All products that have been tested, including those that claim to be "genuine" and "anti-counterfeit," have been found to contain one or both of the following undeclared drug ingredients:
Sibutramine – a controlled substance that was removed from the market in October 2010 for safety reasons. The product poses a threat to consumers because sibutramine is known to substantially increase blood pressure and/or pulse rate in some patients and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias or stroke.
Phenolphthalein – a chemical that is not an active ingredient in any approved drug in the United States. Studies have indicated that it presents a cancer-causing risk.
The FDA has received dozens of adverse event reports, including many serious cardiac issues, associated with the use of Zi Xiu Tang Bee Pollen. Reports have included heart palpitations, tachycardia (increased heart rate), suicidal thoughts, chest pain, diarrhea, anxiety, insomnia, increased blood pressure and seizure. Consumers who have experienced any negative side effects while taking this product should consult a health care professional.
"Products that contain hidden drugs pose a real danger to consumers," said Carol Bennett, acting director of the Office of Compliance in the FDA's Center for Drug Evaluation and Research. "This is especially true when the products have names that mislead consumers into believing they are safe and natural."
Zi Xiu Tang Bee Pollen is manufactured by Guangzhou Zi Xiu Tang Biotechnology Co., Ltd. in Guangdong Province, China. It is offered for sale on the Internet, and it can be found in various retail stores, spas and fitness centers. In addition, licensed health care professionals have promoted the product.
The FDA is investigating the distribution of Zi Xiu Tang Bee Pollen products in the United States and may issue warning letters or take enforcement action, such as seizures, injunctions and/or criminal charges.
