Croton is a diverse and complex taxonomic group of plants ranging from herbs and shrubs to trees. A well-known member of this genus is Croton tiglium, a shrub native to Southeast Asia. It was first mentioned in European literature by Cristóbal Acosta in 1578 as lignum pavanae. The oil, used in herbal medicine as a violent purgative, is extracted from its seeds. Nowadays, it is considered unsafe and it is no longer listed in the pharmacopeias of many countries.
