Rice is a plant. The outer layer of the grain (bran) and the oil made from the bran are used for medicine. Rice bran oil is popular as a “healthy oil” in Japan, Asia, and particularly India. Be careful not to confuse rice bran with other forms of bran such as oat and wheat bran.
Rice bran is used for treating diabetes, high blood pressure, high cholesterol, alcoholism, obesity, and AIDS; for preventing stomach and colon cancer; for preventing heart and blood vessel (cardiovascular) disease; for strengthening the immune system; for increasing energy and improving athletic performance; for improving liver function; and as an antioxidant.
Rice bran oil is also used for high cholesterol.
Some people apply rice bran directly to the skin for an allergic skin rash called eczema (ectopic dermatitis).
