FDA Recalls 2 Herbal Supplements Containing Carcinogens
The US Food and Drug Administration has announced the recall of two herbal supplements because they contain high levels of aristolochic acid, a potent carcinogen and nephrotoxin found in certain plants and botanicals.
Aristolochic acid has been linked with kidney cancer and kidney failure.
Both of the carcinogen-containing products, Tou Tong San (Headache Formula) and Du Huo Ji Scheng Tang (Du Huo Joint Relief), are manufactured by Herbal Science International, Inc.
These dietary supplements are two of twelve items voluntarily recalled by Herbal Science International (also known as Jen-On HerbalScience) because they pose potentially serious health hazards or they contain human placenta, an ingredient banned in the US.
The recalled products were sold on the internet, by acupuncturists, and at herbal stores nationwide. Consumers who purchased the products should immediately discontinue their use and return them to the place of purchase for a full refund. Those who’ve experienced an adverse reaction after taking the products should contact their doctor. Adverse events should also be reported to the FDA’s MedWatch program at 1-800-FDA-1088 or online at www.fda.gov/medwatch/report.htm.
