Overview

Brown rice is “unpolished” white rice. Brown rice retains unsaturated fatty acids, protein, minerals, vitamins, and starch that are usually removed during polishing. It is eaten as food and taken as medicine.

Brown rice is used for diarrhea, upset stomach and other stomach problems, fluid retention, intestinal worms, yellowed skin (jaundice), thiamine deficiency (beriberi), burns, nosebleed, fever, vomiting blood, swelling (inflammation), paralysis, hemorrhoids, and psoriasis and other skin ailments. It is also used as an appetite stimulant, drying agent (astringent), soothing agent (demulcent), and tonic.

How does it work?

It is not known how brown rice might work for medical conditions. Developing research suggests brown rice might help prevent some of the heart-related complications of diabetes. There is also some evidence that it might keep some kinds of cancer cells from multiplying.
