Ingredient Overview
Chinese rhubarb has a long history as a root-based herbal ingredient. This extract is made from root and rhizome, the parts used in herbal preparations rather than culinary rhubarb stalks.
Chinese rhubarb extract is made from Rheum palmatum root and rhizome. The underground parts are central to the herbal history of Chinese rhubarb. This is a different context from eating the fleshy stalks of garden rhubarb in pies or preserves. The root and rhizome provide the characteristic constituents of the dry botanical ingredient.
