Cantharidin is a naturally occurring odorless, colorless fatty substance of the terpenoid class that is produced as an oral fluid in the alimentary canal of the male blister beetle. Available synthetically since the 1950s, topical applications of cantharidin have been used predominantly as a treatment for cutaneous warts since that time.
