Castor oil is derived from the seeds of the Ricinus communis plants that grow wild in wastelands across tropical regions. It is often grown as an ornamental garden plant in milder climates, and now cultivated on a large scale for biodiesel manufacture.
Castor oil is often used to treat constipation. However, research has shown that it can serve as a natural treatment for the face and skin. It is also used to induce labor from old times. The oil starts working as soon as it reached the bowels and many women use it to induce labor. The contraction usually starts 1-3 hours after taking the oral dose of the oil.
