Castor oil is a thick vegetable oil made from castor beans. Common uses include:
* Constipation: Castor oil is a stimulant laxative and can cause a bowel movement within hours. It’s generally intended for occasional, short-term use rather than routine constipation.
* Skin moisturizing: It can act as an occlusive/emollient for dry skin, though some people develop irritation or contact dermatitis.
* Hair/scalp: Often applied to hair or scalp for conditioning and reducing dryness. There isn’t strong evidence that it makes hair grow faster or treats hair loss.
* Cosmetics: Used as an ingredient in lip products, soaps, creams, and other personal-care products.
* Industrial uses: Also used in lubricants, coatings, plastics, and manufacturing.
