We use a high grade, cold pressed organic oil. A superb oil for nourishing dry skin, removing veruccas & removing stag nations from the body. Use externally as a 'castor oil' pack by soaking a flannel in warm castor oil, apply the flannel to your body, cover with a plastic bag, cover with a towel & then with a hot water bottle. Lie back, relax & enjoy! Castor can be used internally as a lubricating laxative. It is a very strong remedy.
