Digestive health
Constipation relief: Castor oil is a powerful natural laxative that stimulates intestinal muscle contractions, promoting bowel movements and easing constipation.
Bowel cleansing: It may be used to empty the colon before certain procedures, such as a colonoscopy, although other preparations might be more effective.
Gut health support: Castor oil can potentially improve gut motility and reduce bloating and discomfort by regulating bowel function and supporting a healthier digestive system. 
Skin and hair health
Moisturizing and hydrating: Rich in fatty acids, especially ricinoleic acid, castor oil acts as a humectant, drawing and trapping moisture in the skin, making it soft and supple.
Potential for acne treatment: Its anti-inflammatory and antimicrobial properties may be beneficial in managing acne breakouts.
Wound healing properties: Ricinoleic acid may promote wound healing due to its anti-inflammatory and pain-relieving effects.
Hair and scalp care: Although evidence is limited, some believe castor oil can nourish the scalp, address dryness and flakiness, potentially strengthening roots and promoting healthier-looking hair, according to www.oaklandlifechiro.com.
Denture cleaning: Its antimicrobial and antifungal properties may be helpful in sanitizing dentures and combating oral infections.
