All parts of the plant are poisonous but the seeds contain maximum concentration of the active principles. The seeds are dark brown in colour, oval in shape and are of the size of smaller variety of castor seeds. Crotin, a toxalbumin and crotonoside, a glycoside are the active principles. Croton oil is extracted from the seeds which is also toxic, though it does not contain the toxalbumin crotin, which is retained in the pressed cake.
