Scientific names: Oryza sativa

Background
Rice bran comes from the outer layer of rice (Oryza sativa). Rice bran oil is popular as a "healthy oil" in Japan, Asia, and particularly India.
Rice bran oil contains substances that might decrease how much cholesterol the body absorbs. Rice bran might also decrease calcium absorption, which might help prevent certain types of kidney stones from forming.
People use rice bran for high cholesterol, diabetes, high blood pressure, athletic performance, and many other purposes, but there is no good scientific evidence to support many of these uses.
Don't confuse rice bran with rice bran arabinoxylan compound, or other forms of bran such as oat bran and wheat bran.
