Castor oil is a vegetable oil cold pressed from the seeds of the castor shrub (botanical name Ricinus communis); it is native to the tropical areas of Africa and India, famous for its oil-rich castor beans. It is a pale-yellow liquid, classified as a type of triglyceride fatty acid, with almost 90 percent of its fatty acid content being a specific and rare compound called ricinoleic acid.
Castor oil and its derivatives are used in the manufacturing of soaps, lubricants, hydraulic and brake fluids, paints, dyes, coatings, inks, cold resistant plastics, waxes and polishes, nylon, pharmaceuticals and perfumes.
Castor oil is loaded with minerals, proteins, vitamin E as well as other nutrients. Thanks to its great health benefits, castor oil has been used externally and internally for thousands of years. Castor oil can deal with the following major ailments and illness: multiple sclerosis, Parkinson’s disease, cerebral palsy, yeast infections, constipation, gastrointestinal problems, menstrual disorders, hair loss, acne, skin inflammation and abrasions, keratosis, hair loss, many vision and eyes ailments.
The best quality of Castor oil is the oil produced by cold pressing and must be free of all chemical solvents, especially hexane, odorless and fresh.
Structure of the major component of castor oil: tri-ester of glycerol and ricinoleic acid
Castor oil is well known as a source of ricinoleic acid, a monounsaturated, 18-carbon fatty acid. Among fatty acids, ricinoleic acid is unusual in that it has a hydroxyl functional group on the 12th carbon. This functional group causes ricinoleic acid (and castor oil) to be more polar than most fats. The chemical reactivity of the alcohol group also allows chemical derivatization that is not possible with most of other vegetable oils.
United States FDA has categorized castor oil as “as safe and effective” used as a laxative with its major site of action the small intestine where it is metabolized into ricinoleic acid. Despite castor oil being widely used to induce labor in pregnant women, to date there is not enough research to show whether it is effective to ripen the cervix or induce labor.
Therapeutically, modern drugs are rarely given in a pure chemical state, so most active ingredients are combined with excipients or additives. Castor oil, or a castor oil derivative such as Kolliphor EL (polyethoxylated castor oil, a non-ionic surfactant), is added to many modern drugs, such as:
- Miconazole, an antifungal agent
- Paclitaxel, a mitotic inhibitor used in cancer chemotherapy
- Sand-immune (cyclosporine injection, USP), an immunosuppressant drug widely used in connection with organ transplant to reduce the activity of the patient’s immune system
- Nelfinavir mesylate, an HIV protease inhibitor
- Tacrolimus, an immunosuppressive drug (contains HCO-60, polyoxyl 60 hydrogenated castor oil)
- Optive Plus (carboxymethylcellulose, castor oil) and Refresh Ultra (glycerine, castor oil), are artificial tears to treat dry eye
Castor oil is also one of the components of Vishnevsky liniment, a topical medication which has been used to treat wounds, burns, skin ulcers and suppurations. Developed by Russian surgeon Alexander Vishnevsky in 1927, the liniment contains birch tar, xeroformium (bismuth tribromophenolate) and castor oil which have been broadly used as a topical medication in the former Soviet Union
Castor oil has traditionally been used as a remedy for treating various skin conditions and infections, relieving constipation, and increasing the health of hair. However, recent studies have shown that castor oil can be used to support the immune system, and an anti-inflammatory agent, antimicrobial agent, and lymphatic stimulant.
You can use castor oil in a couple of different ways. Apply it directly to the skin, use it through a castor oil pack, or mix it with other oils to use it as a topical remedy. Orally, add it to milk or lukewarm water or taken in the form of a supplement.
