Castor oil

Castor oil is a vegetable oil obtained by pressing the seeds of the castor oil plant (Ricinus communis). The common name ``castor oil'', from which the plant gets its name, probably comes from its use as a replacement for castoreum, a perfume base made from the dried perineal glands of the beaver (castor in Latin).
