O tal vez se refiere a:

\"Croton is an extensive plant genus of the family Euphorbiaceae established by Carolus Linnaeus in 1737. The common name for this genus is rushfoil and croton, but this latter also refers to Codiaeum variegatum. The genus name comes from Greek Kroton, which means ticks, because of the seeds\' ressemblance to ticks.

The best known member of this genus is probably Croton tiglium, commonly called croton, a tree or shrub native to Southeast Asia. Croton oil, used in herbal medicine as a violent purgative, is extracted from its seeds.\"
