What Is Castor Oil Used For

 Avatar

Castor oil is primarily used as a natural laxative to relieve temporary constipation and is the only use approved by the U.S. Food and Drug Administration (FDA)[5]. It stimulates the intestines to promote bowel movements. Additionally, castor oil is commonly employed in skin and hair care, where it acts as a moisturizer, may help manage acne, reduce inflammation, and improve texture due to its high content of fatty acids and ricinoleic acid[3][4].

Some traditional and alternative uses of castor oil include:

  • Wound healing: It may promote wound healing and reduce dryness when applied topically[3].
  • Joint and muscle relief: Its anti-inflammatory properties are utilized in massage for sore muscles and arthritis[1].
  • Relieving menstrual cramps: Some anecdotal reports suggest benefit when used as part of a castor oil pack[2].
  • Improving hair health: Castor oil is used as a conditioner to moisturize hair, strengthen strands, and promote scalp health[2].
  • Treating minor skin conditions: Used for acne, stretch marks, and dry skin due to its moisturizing and anti-inflammatory properties[1][4].
  • Potential respiratory health promotion: Some preparations, especially Jamaican black castor oil, are used in topical packs intended to support lung health[2].

Less-supported or anecdotal uses of castor oil—such as general body detoxification, breaking up tumors, or universal health remedies—lack scientific evidence[7]. While castor oil has a long history in folk medicine, most scientific support is limited to temporary constipation relief and moisturizing effects[5].

Castor oil should not be used for long-term constipation, nor for labor induction or by pregnant women without medical supervision, as risks and side effects can arise[5][6].
