Croton (genus) : ウィキペディア英語版 | Croton (plant)
''Croton'' is an extensive flowering plant genus in the spurge family, Euphorbiaceae. The plants of this genus were described and introduced to Europeans by Georg Eberhard Rumphius. The common names for this genus are rushfoil and croton, but the latter also refers to ''Codiaeum variegatum''. The generic name comes from the Greek ('), which means "tick" and refers to the shape of the seeds of certain species. ==Characteristics== The best known member of this genus is probably ''Croton tiglium'', commonly called croton, a tree or shrub native to Southeast Asia. It was first mentioned in European literature by Cristóbal Acosta in 1578 as lignum pavanae. Croton 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.
