Castor oil – Properties, benefits, uses and contraindications

Castor Oil: What is it?

Castor or castor oil is multipurpose vegetable oil. It is obtained from the extraction and processing of the Ricinus communis plant seeds. Due to its multifaceted properties, castor oil is used in the food and cosmetic industries. Its medicinal properties as a laxative treatment for osteoarthritis and skin infections make this product a potential substitute for certain traditional medicines. What are its contraindications?
