Although many people initially considered the Castor plant to be an overrun and unwanted weed, the fine oil produced from its seeds contained benefits that would soon become known all around the world. The advantages of Castor Oil were made popular by Edgar Casey, a man who was considered to be “the Father of Holistic Medicine.” He taught the public about its healing properties for a vast range of health issues and the potent Castor Oil remedy became known as “Palma Christi,” or “Hand of Christ.”

Ricinus communis, better known as the Castor plant, is native to the Mediterranean region as well as the tropical regions of Africa and India, but it also grows in other tropical regions. Oil-rich Castor seeds, or the “beans,” were traditionally used without their hulls as a method of controlling not only pregnancy but also leprosy and syphilis. In medicinal applications, Castor beans were made into a paste and applied as a poultice to treat skin inflammation and to ease headaches.

These versatile beans were used to produce paints, industrial lubricating oils, varnishes, as well as the popular cosmetic oil. Historically, Castor Oil was reputed to be a laxative for those suffering from constipation, and it was used by pregnant women to induce labor as well as to prompt the flow of breast milk. Some used it to dissolve cysts, warts, and other growths. Some used Castor Oil in the eyes to soothe irritation caused by dust or other particles; however, it is not advisable to use Castor Carrier Oil for any of these purposes. In Ancient Egypt, Castor Oil was used in wicks to light lamps, and the beans were discovered in tombs that date back to 4000 B.C.

Around the world, Castor Oil continues to be used both cosmetically and medicinally to repair and darken hair while promoting its growth. It is used to soften and soothe irritated or infected skin and to ease muscle aches and joint pains. Castor Carrier Oil and its derivatives are also used in the production of soaps, pharmaceuticals, cosmetics, perfumes. It is ideal for use in or as a massage oil for its moisturizing properties.

Castor oil is valued for its rich fatty acid profile, along with its antioxidant and anti-inflammatory properties. This combination makes it safe for topical use and highly versatile across hair care, skin care, and overall wellness routines.

Its key components include Ricinoleic Acid, Oleic Acid, Linoleic Acid (Omega-6), Alpha-Linolenic Acid (Omega-3), Stearic Acid, and Palmitic Acid, each contributing to its wide range of benefits.

Key Fatty Acids & Their Benefits

Ricinoleic Acid

The primary compound in castor oil, making up nearly 90% of its composition.

• Helps relieve muscle and joint pain

• Supports skin healing and reduces inflammation
• Improves moisture retention
• Lightweight and suitable for oily or acne-prone skin

Alpha-Linolenic Acid (Omega-3)

• Helps reduce inflammation
• Supports joint comfort and flexibility
• Plays a role in healthy circulation

Stearic Acid

• Gently cleanses and removes excess oil and buildup
• Helps stabilize and extend the shelf life of products
• Conditions and protects hair without weighing it down

Castor Oil Benefits for Hair

Castor oil helps support healthier, fuller-looking hair by stimulating circulation to the scalp and locking in moisture. This makes it especially beneficial for dry, brittle, or damaged hair, leaving it smoother, shinier, and softer.

Its antifungal and antimicrobial properties help maintain a healthier scalp by reducing dandruff and buildup. With consistent use, hair can appear thicker, stronger, and more resilient over time.

Castor Oil Benefits for Skin

Rich in vitamins and fatty acids, castor oil deeply hydrates and nourishes the skin. It helps improve elasticity, soften texture, and promote a more youthful appearance.

Its anti-inflammatory and antibacterial properties make it especially beneficial for acne-prone skin, as it penetrates easily without heavily clogging pores. Over time, it may help reduce the appearance of blemishes, scars, stretch marks, and uneven skin tone while protecting against environmental stressors.

Castor Oil Benefits for Health

Traditionally used for its therapeutic properties, castor oil can help soothe inflamed or irritated skin and relieve sore muscles and joint discomfort, making it ideal for massage.

Its antimicrobial properties make it useful for minor cuts and skin irritations, while its warming effect helps boost circulation. It has also been used to support detoxification and improve overall skin health.

The Castor plant can grow on a vast range of soil types, as long as they are deep and have adequate water drainage. The ideal soil is a well-drained, deep, loamy sand with a pH of approximately 6 that is moderately fertile, free of weeds, and has somewhat acidic conditions.

In India, the beans are sown either at the beginning of the rainy season between late May and early June or they are planted at the end of the rainy season between late September and early October. Planting the beans at one of these two times helps ensure that the second half of the crop’s life can avoid wet weather. In tropical regions, the harvest begins before the rainy season (November in India), while in dry regions, the beans are harvested when they have all reached maturity. Harvesting is done largely by hand in tropical areas.

During the harvesting process, the spikes of the pods are first broken off, then the capsules are stripped off into a wagon, sled, or into containers worn by the harvesters. If the capsules are not already dry when they are picked, they must be spread out and dried. In India, they are spread out to dry under the sun until they become black. The beans are removed from the capsules – usually being beaten out with sticks in India – then they are winnowed and screened to remove the beans’ outer coverings or “hulls” along with any unwanted particles. A regular thresher, which is a machine that separates the outer coating of the bean from the plants by beating, is not usually a suitable tool for de-hulling the seed, as the soft seeds would be broken by the thresher’s beater bar or peg drums. Instead, the seeds may be decorticated by being rubbed against a rubbing board.

As with all other New Directions Aromatics products, carrier oils are for external use only. The beans/seeds of the Castor plant contain a toxic byproduct called Ricin. Although the heat of the oil extraction process deactivates it and deprives it of its natural properties, this inactive ingredient can still cause an allergic reaction. Attempts are being made to discover alternative hydroxy fatty acid sources and to modify the Castor plant in order to prevent Ricin from synthesizing with the oil.

Potential allergic reactions that could be caused by the topical application of Castor Oil include: itching, rashes, redness, and a stinging sensation. More severe side effects can include difficulty breathing, dizziness, and swelling of the face and throat. It is highly advised that a small skin patch test be conducted 24 hours before Castor Oil is applied topically in larger amounts. Slight itching or redness on any user will indicate that Castor Oil is not suitable for use on that individual, as there is a risk of experiencing an allergic reaction.
