Ursodiol (UDCA; Ursodeoxycholic acid) is a novel and natural bile acid with significant colon chemopreventive activity. As a secondary bile acid, it is produced in humans and most other species from metabolism by intestinal bacteria. It is synthesized in the liver in some species (e.g. the Chinese black bear liver), and was first identified in bear bile, which is the derivation of its name Ursus. In purified form, it has been used to treat or prevent several diseases of the liver or bile ducts in China for centuries.
