Castor Oil Plant (Ricinus communis)

Ricinus communis, commonly known as the castor oil plant, is a fast-growing perennial shrub or small tree in the Euphorbiaceae family. Native to East Africa but widely cultivated in tropical and subtropical regions, it is valued for its seeds, which are the source of castor oil used in medicine, cosmetics, and industrial applications. Traditionally, various parts of the plant—including seeds, leaves, and roots—have been used for their laxative, anti-inflammatory, and antimicrobial properties, although the seeds contain toxic ricin and must be processed carefully. With its multifaceted uses and economic importance, Ricinus communis remains a significant plant in agriculture and traditional medicine.
