Also produced by the Chinese black bear liver, ursodiol has been used in the treatment of liver disease for centuries.  This agent dissolves or prevents cholesterol gallstones by blocking hepatic cholesterol production and decreasing bile cholesterol.  Ursodiol also reduces the absorption of cholesterol from the intestinal tract."}]
