Castor oil is a thick vegetable oil extracted from Ricinus communis seeds. Its main approved medical use is as a natural stimulant laxative. It is also widely used in cosmetics, skin care, and hair treatments due to its high ricinoleic acid content.
Health and Medical Uses
Relieving Constipation: Taken by mouth in small, controlled doses, it stimulates bowel movements through its action in the intestine. (Note: It can cause severe cramping and diarrhea and should not be used long-term.)
Wound Care: Applied topically, it helps maintain a moist environment on minor cuts or abrasions to support healing.
Castor Oil Packs: Flannel cloth soaked in the oil is placed on the abdomen or joints; while popular in traditional routines for soothing minor muscle or period discomfort, scientific backing is minimal outside of the soothing heat from an added pad.
Skin and Beauty Uses
Skin Moisturizer: Deeply hydrates dry skin and locks in moisture because it is rich in fatty acids.
Hair and Scalp Conditioning: Massaged into the scalp to help soften dry hair, add shine, and soothe irritation, though direct proof for accelerated hair growth is mostly anecdotal.
Eyelashes and Eyebrows: Dabbing a tiny amount can give a thicker, glossier appearance.
Lip and Cuticle Care: Used to soften chapped lips, dry cuticles, and cracked heels.
