Complete Guide to the Castor Plant, Its Origins, Names, and Uses

Castor, scientifically known as Ricinus communis, is a tropical plant that is widely known for its seeds, which are used to extract castor oil. In Hindi, it is called "Arandi", and it has a rich history of use in traditional medicine, industrial applications, and beauty care.

Despite being a humble-looking plant, castor plays a massive role in multiple industries — from pharmaceuticals to cosmetics to agriculture. In this article, we’ll explore everything you need to know about castor: what it is, where it is grown, its alternative names in different languages, and its wide range of uses.

Castor is a perennial flowering plant that grows in warm climates and is known for its large, glossy leaves and unique spiny fruit pods that contain castor seeds. These seeds are the source of castor oil, a thick, pale-yellow liquid packed with nutrients like ricinoleic acid, which makes it highly valuable in medicine and skincare.

Though the seeds are useful, they are also highly toxic in raw form due to a compound called ricin. However, the oil extracted from castor seeds is safe and beneficial when processed correctly.
