Castor seed is an oilseed produced by castor plants belonging to the botanical family ‘Euphorbiaceae’. Its scientific name is ‘Ricinus communis’ and is used mainly for certain medicinal purposes.

The Castor plant is supposed to have originated from Northeastern Africa, especially Ethiopia and Somalia. It has reportedly been used by humans since more than 6000 years ago and has even been mentioned in the Bible.

Castor plants grow naturally In a wide variety of soils. Nevertheless, well-drained sandy loam soils with slightly acidic conditions and warm climates are ideal for the same that are botanically large shrubs or small trees and grow 6-15 feet in height. The plants normally take 5-6 months to start bearing the seeds. It is traditionally a Kharif season crop, but the plants bear fruits depending on the varieties and climatic conditions. The varieties of castor are categorized based on the duration of harvest, stem and leaf colour, oil content, size of the seeds, etc. Some of the main high-yielding castor seed varieties available in India are GAUCH-4NPH-1, YRCH1, TMV 5, TMV 6, TMVCH and CO1.

Castor seeds are oval-shaped, glassy and brown coloured and have many medicinal properties. However, they also contain ricin, which is poisonous and can even cause death to animals and humans if consumed through improper methods or without enough care.

The seeds are mainly used to make castor oil which was used as lamp fuel in the olden days and now mainly for certain medicinal purposes to reduce inflammation and pain, heal wounds and scars, soothe dry eyes, calm arthritis and grow and protect hair.
