Chinese Herbal Supplements Recalled, Contain Carcinogen Linked to Kidney Disease

A New York City company is recalling two Chinese herbal supplements because they contain a carcinogen linked to kidney disease, the company said Wednesday.

Kingsway Trading Inc. of Brooklyn said it is recalling its dietary pills Double Deers Formula brand Expellin Extract (Concentrated) and Cardioflex. The company said it stopped distribution of the products after being notified by the Food and Drug Administration that they contain aristolochic acid, a carcinogen and toxin found in plants that has been associated with some cases of kidney failure and an increased risk of kidney cancer.

Expellin extract has been marketed to relieve headaches and sinus congestion, while Cardioflex is suggested for maintaining cardiovascular and circulatory health. Both supplements were imported from China and distributed nationwide through retailers and acupuncture clinics since May 2000.

The FDA confirmed the recall Wednesday and advised consumers who have taken the products to contact their health care provider immediately. No illnesses related to the products have been reported, the company and the FDA said.

“Even if these products have not been used recently, consumers should still inform their health care provider about which product they took, so that an appropriate evaluation may be conducted,” said FDA spokeswoman Kimberly A. Rawlings.

The recall covers all lots of the two products, a total of 2,873 units, the company said.

Consumers can return the recalled products to their place of purchase for a full refund. The company can be contacted with questions at 718-366-2300.
