Pronunciation

Castor Oil Plant: /ˈkæstər ɔɪl plænt/

Etymology

The term "castor oil" comes from its use as a replacement for castoreum, a perfume base made from the dried perineal glands of the beaver (castor in Latin). The plant is named Ricinus communis which is derived from the Latin word Ricinus meaning "tick", due to the seed's resemblance to a particular species of tick.
