Tokoro Rhizome Chinese Herb
Tokoro Rhizome (Bi Xie): A Neutral Herb for Dampness, Turbid Urine, and Wind-Damp Pain
Introduction
Tokoro rhizome, known as Bi Xie (萆薢) in Traditional Chinese Medicine (TCM), is a neutral, bitter herb used to separate pure from turbid fluids, drain dampness, and treat painful obstruction. It is especially valued for conditions involving cloudy or milky urine, vaginal discharge, joint pain, and damp-heat in the lower burner. Its unique function of “separating the clear from the turbid” makes it ideal for urogenital and arthritic complaints.
What Is Tokoro Rhizome?

It is prized for its ability to resolve dampness, clear turbidity, and dispel wind-damp from the muscles and joints without being overly drying or harsh.
