Red yeast rice is a fermented rice common in both Japan and China. It is eaten for basic nutritional benefits and also functions as an herbal supplement. In the West, red yeast rice is popular as a natural cholesterol reducing agent, as it contains a naturally-occurring compound called mevinolin, also known as lovastatin.
