The castor oil plant (Ricinus communis) is a plant species of the Euphorbiaceae and the sole member of the genus Ricinus and of the subtribe Ricininae. It is the origin of the castor bean which, despite its name, is not a true bean. The name Ricinus is a Latin word for tick; the seed is so named because it has markings and a bump at the end which resemble certain ticks. It is the source of castor oil, which has a wide variety of uses, and ricin, a poison (the ricin from 1-2 seeds can kill an adult).
