Castor oil is a thick, odorless oil made from the seeds of the castor plant. The oil has ancient roots, where it was used as a fuel for lamps, healthcare, and beauty purposes. It still is one of the most used products globally, as a laxative, and in skin and hair products. While the research to determine the benefits of castor oil is still ongoing, experts indicate that it might have potential health benefits.

9 health benefits of using castor oil

Relieves constipation
Castor oil is the only product approved as a natural laxative by the FDA to relieve temporary constipation.

Its ricinoleic acid attaches to a receptor in the intestines, which causes the muscles to contract, pushing feces through the colon. The oil might also occasionally be utilized to clean the colon before a procedure like a colonoscopy. A healthcare expert might prescribe other laxatives that could offer better results. One should note that castor oil is not a long-term solution for constipation as it could lead to side effects like cramps and bloating. One should contact their healthcare provider if constipation lasts more than a few days.

Helps induce labor
The oil has been used for centuries to help induce labor and delivery.

Experts suggest that ingesting small amounts of castor oil may cause spasms in the intestines, which could stimulate the bowels and vagal nerve. The spasm-and-stimulation combination may further irritate the uterus, which could lead to contracting. Experts also believe that castor oil might reduce fluid absorption and electrolytes in the small intestine. The phenomenon might cause diarrhea and contractions. The oil could also promote the release of prostaglandin receptors, leading to the cervix dilating.

Getting rid of stretch marks
Stretch marks might be caused by pregnancy and a sudden increase in body mass. It could also result from hormonal imbalance, aging, and swelling. For such cases, one could speak to an expert about using castor oil to help reduce stretch marks. Its rich content and various fatty acids make it an ideal moisturizer for getting rid of unsightly stretch marks.

Works as a natural moisturizer
Castor oil is abundant in ricinoleic acid, which is a monounsaturated fatty acid that can be used to moisturize the skin. The properties act as occlusive moisturizers, which prevent or reduce water loss through the outer layer of the skin. Manufacturers use castor oil in cosmetics, such as lotions, makeup, and cleansers, to promote hydration. One could also purchase the oil in its pure form as a natural alternative to store-bought moisturizers and lotions. However, one must speak to an expert before applying it to the skin.

Promotes wound healing
Those who apply castor oil to a wound may benefit from its healing effects as it may help prevent sores from drying out. Various renditions of ointments contain a mixture of castor oil and Peru balsam. These ointments are used as a dressing for chronic and acute wounds and skin ulcers such as pressure ulcers, diabetic ulcers, burns, and surgical wounds. Ointments with castor oil help reduce odors, protect wounds, and create a moist environment to promote healing. Even the ricinoleic acids found in castor oil have anti-inflammatory and pain-reducing properties that could help reduce skin inflammation, aid pain reduction in people with wounds, and support healing.

Improves hair health
Several individuals use castor oil to benefit the health of their hair. Castor oil could help treat conditions like dry scalp and dandruff and improve hair growth, making it a good option as a natural remedy. However, the research for this is still ongoing. This is because the oil has moisturizing properties that could help lubricate the hair shaft, increase flexibility, and reduce the chance of breakage. One should speak to a healthcare provider before applying any type of remedy to their hair.

Effective remedy for arthritis
Experts believe that castor oil could be beneficial for people with arthritis. The oil’s anti-inflammatory properties make it an excellent massage oil, benefiting one’s arthritic joints, inflammation of the nerves, and sore muscles. Furthermore, the ricinoleic acid present in castor oil can boost anti-inflammatory properties within the body and is considered a safe remedy for arthritis pain. There are various ways in which one can manage arthritic pain; it is advisable to consult a healthcare professional, such as a physical therapist, for advice.

For cleaning and storing dentures
Some bacteria and fungi, including Candida fungi, commonly grow on dentures. The process may create oral complications if the removable oral appliance is not cleaned and stored properly. An overgrowth of the fungi may lead to a condition called denture stomatitis, an infection that leads to inflammation, irritation, and redness in the mouth. As a remedy, an expert might recommend cleaning dentures with castor oil to eliminate bacteria and fungi.

Improved immune function
A healthcare professional might recommend using castor oil regularly to improve immune system function, including lymphatic draining, blood flow, and thymus gland health. The lymphocytes – a type of white blood cell found in the body’s immune system – attack perceived threats to the body and invaders like bacteria and toxins. So, using castor oil may help the body produce proper levels of lymphocytes, which are stored and released into the lymphatic tissue from the lymph nodes, thymus gland, and tissue from the small intestine.
