Many People Associate Castor Oil With Being A Cure For Constipation, But It Has Other Potential Uses, Such As Inducing Labor, Relieving Arthritis Pain, And Improving Skin. Most Of Its Claimed Benefits Aren'T Supported By Much Evidence, However. Castor Oil Supplements Can Cause Side Effects Such As Diarrhea, Abdominal Cramps, Nausea, And Even Fainting And Hallucinations. Topical Use Can Trigger A Rash. Don'T Use It If You Are Pregnant Or Give It To A Child Without Consulting A Healthcare Provider First.
