The major health-giving acid in castor oil is ricinoleic acid, a monounsaturated fatty acid that constitutes 85-90% of the oil's composition.

This unique acid, characterized by a hydroxyl group on the 12th carbon atom, is responsible for many of castor oil's therapeutic properties, including its potent anti-inflammatory, antimicrobial, and laxative effects. Ricinoleic acid is produced when castor oil is hydrolyzed in the small intestine and acts by stimulating intestinal peristalsis through interaction with EP3 prostanoid receptors.

Its presence also contributes to the oil's ability to promote wound healing, improve skin health, and potentially stimulate hair growth by enhancing scalp circulation.
