27 Health Benefits of Castor Oil

2. Boosts the Immune System

Castor oil is best known for its laxative effect. When taken orally in small amounts, it can stimulate the intestines and relieve temporary constipation. This happens because the oil is rich in ricinoleic acid, a fatty acid that acts on the intestinal muscles to trigger movement. It’s important to use castor oil sparingly, though—too much can lead to cramping or dehydration. Anyone experiencing chronic constipation should consult a doctor rather than relying on castor oil long-term.
