Ricin, a lectin (a carbohydrate-binding protein) produced in the seeds of the castor oil plant, Ricinus communis, the seeds are crushed to extract castor oil. As ricin is not oil-soluble, little is found in the extracted castor oil. These seeds, which are known as castor beans, contain a toxic enzyme called ricin. However, the heating process that castor oil undergoes deactivates it, allowing the oil to be used safely.
Castor oil is a vegetable oil pressed from castor beans. The name probably comes from its use as a replacement for castoreum. Castor oil is a colourless to very pale yellow liquid with a distinct taste and odor. Its boiling point is 313 °C and its density is 961 kg/m3.Is most commonly used as a skin moisturiser to hydrate and soften skin. With its high vitamin E and fatty acid content,
argan oil is the ideal product to give skin a natural boost. It absorbs easily and is non-greasy and non-irritating, which makes it a great natural moisturiser.
A Powerful Laxative – Perhaps one of the best-known medicinal uses for castor oil is as a natural laxative. It’s classified as a stimulant laxative, meaning that it increases the movement of the muscles that push material through the intestines, helping clear the bowels. Stimulant laxatives act rapidly and are commonly used to relieve temporary constipation. When consumed by mouth, castor oil is broken down in the small intestine, releasing ricinoleic acid, the main fatty acid in castor oil. The ricinoleic acid is then absorbed by the intestine, stimulating a strong laxative effect. In fact, several studies have shown that castor oil can relieve constipation. For example, one study found that when elderly people took castor oil, they experienced decreased symptoms of constipation, including less straining during defecation and lower reported feelings of incomplete bowel movements. While castor oil is considered safe in small doses, larger amounts can cause abdominal cramping, nausea, vomiting and diarrhea . Although it can be used to relieve occasional constipation, castor oil is not recommended as a treatment for long-term issues. Castor oil can be used as a natural remedy for occasional constipation. However, it can cause side effects like cramping and diarrhea and should not be used to treat chronic constipation.
A Natural Moisturizer – Castor oil is rich in ricinoleic acid, a monounsaturated fatty acid.
These types of fats act as humectants and can be used to moisturize the skin. Humectants retain moisture by preventing water loss through the outer layer of the skin. Castor oil is often used in cosmetics to promote hydration and often added to products like lotions, makeup and cleansers. You can also use this rich oil on its own as a natural alternative to store-bought moisturizers and lotions.
Many popular moisturizing products found in stores contain potentially harmful ingredients like preservatives, perfumes and dyes, which could irritate the skin and harm overall health.
Swapping out these products for castor oil can help reduce your exposure to these additives.
Plus, castor oil is inexpensive and can be used on the face and body. Castor oil is thick, so it’s frequently mixed with other skin-friendly oils like almond, olive and coconut oil to make an ultra-hydrating moisturizer.
Keeps Your Hair and Scalp Healthy – Many people use castor oil as a natural hair conditioner. Dry or damaged hair can especially benefit from an intense moisturizer like castor oil. Applying fats like castor oil to the hair on a regular basis helps lubricate the hair shaft, increasing flexibility and decreasing the chance of breakage. Castor oil may benefit those who experience dandruff, a common scalp condition characterized by dry, flaky skin on the head.
Though there are many different causes of dandruff, it has been linked to seborrhoeic dermatitis, an inflammatory skin condition that causes red, scaly patches on the scalp. Due to castor oil’s ability to reduce inflammation, it may be an effective treatment for dandruff that is caused by seborrhoeic dermatitis. Plus, applying castor oil to the scalp will help moisturize dry, irritated skin and may help reduce flaking.
