Castor oil is a tasteless and odorless vegetable oil that is extracted by pressing of the seeds of the castor plant, scientifically known as Ricinus communis. Castor seeds are rich in triglyceride, which is what makes them so valuable. They also contain small amounts of a toxin called ricin, which is potentially deadly in concentrated or excess amounts.
The health benefits of castor oil include boosting immunity, skin and hair care, and relieving rheumatism, menstrual disorders, and constipation. It also helps in inducing labor and improving lactation.
Castor oil improves the lymphatic function, blood flow, and thymus gland health. According to recent research, it promotes the production of lymphocytes in the body which helps in fighting the toxins and other bacteria present in the body.  Thanks to its ricinoleic acid content and immunity-boosting effects, it is often used as an effective purgative, thereby also preventing inflammation.
Side Effects & Precautions Castor oil can have a few side effects including the following:
Pregnancy: If administered to pregnant women in higher dosages, it may also cause abortion. However, this second mode of birth control can be fatal for the mother too and is rarely recommended. It can also cause excessive pelvic contractions which can lead to a miscarriage or premature delivery.
Skin: The skin can sometimes break out when exposed to castor oil as the concentration of chemicals in castor oil make it dangerous. Other Side Effects:
Sore throat, chest pain, and difficulty in breathing
