FDA cracks down on companies pushing vegetable extracts and creams as cancer cures

Asparagus extract. Exotic teas. Topical creams for your pet — and you. These and dozens of other products are being touted falsely as having "anti-cancer" properties, according to federal regulators who are trying to stop the practice.

The Food and Drug Administration, in warning letters released Tuesday, ordered 14 companies to stop making the bogus claims or face possible seizures of their products and criminal prosecution. The letters covered more than five dozen unapproved products that the companies said could prevent, treat or cure cancer, the FDA said. The items included pills, ointments, oils, drops, teas and diagnostic devices.
