The castor oil plant Ricinus communis, also known as Palma(e) Christi or wonder tree, is a perennial scrub of the spurge family Euphorbiaceae. Ricinine can be found in all parts of the plant and it is a quite strong insecticide. The castor seeds contain approximately 0.2% of the alkaloid. R. communis contains a complex cocktail of toxic substances including the type II ribosome-inactivating protein (RIP) ricin, the haemagglutinin RCA120 and the alkaloid ricinine.
