Santonin is a drug which was widely used in the past as an anthelminthic, a drug that expels parasitic worms (helminths) from the body, by either killing or stunning them. Santonin was formerly listed in U.S. and British pharmacopoeia but has fallen out of use with the development of safer ascaricides and is no longer registered as a drug in most countries.
