FDA Warns Against Using Chinese Herbal Formula

The U.S. Food and Drug Administration (FDA) is advising consumers not to buy or use Super Shangai, Strong Testis, Shangai Ultra, Shangai Ultra X, Lady Shangai, and Shangai Regular, also marketed as Shangai Chaojimengnan, products.

These products, which originate in China, are being marketed for the treatment of erectile dysfunction (ED) and for sexual enhancement. Although labeled as dietary supplements, these products do not qualify as dietary supplements because they contain undeclared active ingredients of FDA-approved prescription drugs for erectile dysfunction. The products are thus drugs that are illegal because they lack FDA approval.

The undeclared ingredients in these products may interact with nitrates found in some prescription drugs (such as nitroglycerin) and can lower blood pressure to dangerous levels. Consumers with diabetes, high blood pressure, high cholesterol, or heart disease often take nitrates. ED is a common problem in men with these medical conditions. Because they may have been advised against taking ED drugs, they may seek out products like these because they are marketed as "all natural" or as not containing the active ingredients in approved, prescribed ED drugs. Additionally, because the manufacturing source of the active ingredients in these products is unknown, consumers should be aware that the safety, efficacy, and purity of these ingredients can not be validated.
