Unsavory as it may sound to most Americans, urine therapy refers to the use of one’s own urine to promote or maintain health. Proponents of the therapy assert that a person’s urine can be swallowed, applied to the skin, injected, sniffed, or used as an enema, eye drops, or ear drops. While the use of urine for therapeutic purposes is regarded with great skepticism by virtually all conventional physicians, the therapy nevertheless has a long history in many countries around the world. The Greeks and Romans are said to have used urine as medicine, and the practice is common today in China and India.
