Red Yeast Rice Overview

Red Yeast Rice Red yeast rice is a type of fermented rice produced by the cultivation of a type of yeast called Monascus purpureus. The rice is soaked in water and then allowed to ferment with the yeast for several weeks. During the fermentation process, the rice turns a deep red color and develops a distinctive, slightly sweet, and sour taste. Red yeast rice has a long history of use in traditional medicine and has been used as a natural remedy for a range of health conditions, including high cholesterol, high blood pressure, and heart disease. Red yeast rice is thought to work by inhibiting the production of cholesterol in the liver and by helping to improve circulation. Red yeast rice contains a compound known as mevinolin, which is identical to the FDA-approved drug lovastatin.
