Women Have Trusted Castor Oil for Over 3,000 Years From the Nile to the Caribbean, it was the warm, simple ritual passed from mother to daughter.

For thousands of years, women across the world have turned to castor oil. Egyptians used it on their skin, Indian healers used it in massage, and Caribbean grandmothers still swear by it today. The ritual was always the same: slow down, warm the body, and take care of yourself. The Cramp Night Kit brings that ritual into your life, without the mess.
