What Is Caster Oil Good For?

Castor oil is a colorless, tasteless oil derived from the castor bean. Although it may be best known for its medical uses, it also has a variety of industrial uses.

Laxative

• Castor oil is traditionally used as a laxative. Although it is generally effective and safe for treating constipation, it is not the best medicine. Because it is a traditional medicine, it has not been examined as thoroughly by the Food and Drug Administration as a new medicine would be and, as a result, is considered less safe.

Medicine Additive

• Castor oil is added to a variety of medicines ranging from antifungal agents to skin creams as a preservative or for other purposes. For example, it is used in skin creams because it is effective at penetrating the skin, and it is used as a vehicle in some IV injections.

Food Additive

• Small amounts of castor oil are sometimes added to food as a preservative. Castor oil can prevent fungal growth.

Industrial Uses

• Castor oil has a wide range of industrial uses from adhesives to leather treatments to paints. Castor oil also had an important role as an engine lubricant in early airplanes.

Biofuel

• Research is currently being done in Ethiopia to determine whether castor oil can be grown and used as a biofuel.
