What is Castor Oil

Castor oil is a vegetable oil pressed from castor beans. It is a pale yellow oil which has a very thick and sticky consistency and are well known as a source of ricinoleic acid, a monounsaturated, 18-carbon fatty acid. Castor-oil plant, (Ricinus communis), also called castor bean, is a large plant of the spurge family (Euphorbiaceae), grown commercially for the pharmaceutical and industrial uses of its oil and for use in landscaping. Probably native to tropical Africa, the castor-oil plant has become naturalized throughout warm areas of the world. The plants are chiefly cultivated in India, China, and Brazil, largely as the source of castor oil.

The United States Food and Drug Administration (FDA) has categorized castor oil as “generally recognized as safe and effective” (GRASE) for over-the-counter use as a laxative. Despite castor oil being widely used in an attempt to induce labor in pregnant women, to date there is not enough research to show whether it is effective to dilate the cervix or induce labor. Some pregnant women choose to take castor oil to hurry up their labor, although every doctor in the world recommends against this. Because it works as a laxative, it can actually cause dehydration if you take it without actually needing the laxative effects.

Benefits of Castor Oil

In naturopathy castor oil has been promoted as a treatment for a variety of human health conditions, including cysts. Castor oil has  also been used in cosmetic products like creams, moisturizer and in cold process soap making to increase lathering in the finished bar. It’s also been used to enhance hair conditioning in hair care products and for supposed anti-dandruff properties.

Studies suggest that many of castor oil’s benefits come down to its chemical composition. It’s classified as a type of triglyceride fatty acid, and almost 90 percent of its fatty acid content is a specific and rare compound called ricinoleic acid.

Ricinoleic acid is not found in many other plants or substances, making the castor plant unique since it’s a concentrated source.

Aside from its primary constituent, ricinoleic acid, castor oil also contains other beneficial salts and esters that mainly act as skin-conditioning agents. This is why, according to a report published in the International Journal of Toxicology, this oil is used in over 700 cosmetic products and counting.

Uses of Castor Oil

Castor oil is a ‘wonder oil’ that has numerous benefits associated with it. Castor oil, which has been in use for hundreds of years for its anti-bacterial properties and anti-inflammatory properties, is known for its benefits. In fact, castor oil is used extensively in soaps, massage oils, cosmetics and medicines. Some of the famed uses of castor oil includes the application on face and hair.

Castor Oil for Face

Castor oil is completely natural and free of synthetic chemicals (as long as you use 100 percent pure castor oil, of course), yet it’s rich in skin-boosting ingredients like fatty acids.

Applying this oil to dry or irritated skin can help to discourage dryness and keep it well moisturized, since it prevents water loss.

It can also help with wound and pressure ulcer healing thanks to its moisturizing as well as antimicrobial and antibacterial properties. It mixes well with other ingredients like almond, olive and coconut oil, all of which have unique benefits for skin.

Lab studies have shown that castor oil is effective against many types of bacteria, including Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. Out of all the staphylococcal bacteria, Staphylococcus aureus is considered the most dangerous and can cause mild to serious skin infections and other concerning staph infection symptoms.

As a natural antibacterial agent, castor oil works similarly to coconut oil for boosting skin health. It also makes a great general skin moisturizer and anti-inflammatory blemish treatment.

If you want to get rid of acne forever, you need to get to the source of the problem. Castor oil is a great natural home remedy for acne.

As it penetrates deep into the skin, it fights bacteria overgrowth that can clog pores, while softening and hydrating irritated skin at the same time.

As mentioned earlier, this oil has been shown to fight off  Staphylococcus aureus, which is linked to development of acne.

Castor Oil for Hair

Just like coconut oil benefits your hair, using castor oil may help your hair grow faster, thicker, stronger and shinier.

It can detangle hair as well and is even used to treat hair felting (a disorder in which hair becomes twisted and entangled as a hard stony mass).

Does castor oil regrow hair? Because it can improve blood circulation to your follicles, it may help to speed up hair growth.

This is why some people apply it not only to hair on their head, but also to eyebrows and eyelashes.

Studies suggest that ricinoleic acid may treat hair loss by balancing prostaglandin D2 (PGD2) production in men, which affects hair growth.

Castor Oil Pack

Some people believe that the most effective use of castor oil is castor oil packs or poultices. These might be able to help increase topical absorption through the skin’s pores.

You can make your own easily, or purchase a pre-made kit.

To make your own pack you’ll need a bottle of castor oil and a soft piece of fabric, such as flannel that can be found in health stores and online.

  • To make your own pack, saturate a piece of flannel and place it over your abdomen or other painful areas. It takes approximately 3–4 ounces of castor oil to make one pack the size of a washcloth or small hand towel.
  • Wrap castor oil cloth around any painful area. Cover the oiled cloth with another hand towel or a plastic wrap to prevent oil getting on clothes or furniture.
  • You may want to also apply heat to support absorption.
  • Let the pack sit for one hour or more.
  • You can also massage the oil into any area where soothing is desired.
