  • Though castor plant or castor oil is not a food, yet it is one of the most commonly used oils all over the world as a safe purgative and drug for reducing irritation of the skin and alleviating swelling and pain. The castor seed plant contains alkoloid ricinine and toxalbumine ricin. They yield a fixed oil which is used chiefly for medicinal purposes.

Unlike most fixed oils, castor oil possesses the remarkable property of mixing with absolute alcohol and glacial acetic acid in all proportions. The glycerides of ricinoleic acid in castor oil are mainly responsible for its purgative effect.

The castor plant is a small annual plant. It ranges from 1 to 7 meters in height. It has well developed roots, with green and reddish stems which become hollow with age. The fruit is a spherical capsule with small grey seeds with brown spots.

Castor oil plant or castor bean plant, is the common name for a wind pollinated flowering plant, Ricinus communis, of the Euphorbiaceae family, characterized by large, palmately lobed leaves, flowers during most of the year in dense terminal clusters, with female flowers above the male flowers, and clusters of spiny, red to bronze fruit or seed capsules that contain seeds with intricate mottled designs. Castor seeds are the source of both the commercially important castor oil, which has medicinal and industrial uses, and the extremely poisonous ricin, which has been used as a biochemical agent.
