Chinese rhubarb (also called Turkey Rhubarb) has many uses. The edible rhubarb is a variety of this plant. I remember rhubarb pies as a child. It is an astringent, bitter tasting herb. It also has cooling properties.
The uses range from a laxative to a remedy for gout. Traditionally, it is used in cancer. I have used this rhubarb for post menopausal symptoms. Most think of black cohash for menopause. I think of turkey rhubarb. The company Metagenics uses it in a product called Estrovera. It contains no estrogen.
