What is Black Rice Extract?
Black rice extract is a crude mixture of compounds extracted from black rice which have the medicinal properties and the history of traditional use. In other words, black rice extract is a concentrated mixture made by extracting (or ''pulling'') black rice's chemical constituents out of the inert plant fiber (cellulose) with a solution of grain alcohol and water. Good black rice extract should optimally preserve the aroma, taste and biological activity of black rice from which it is made.
