Bi Xie Fen Qing Yin (Tokoro Combination), also known as Dioscorea Hypoglauca Decoction to Separate the Clear, is a classical formula in Traditional Chinese Medicine that warms the kidneys, drains dampness, and separates the clear from the turbid.
It is particularly effective for kidney yang deficiency with cold-dampness in the lower jiao, addressing urinary frequency, frequent urination, painful urination, cloudy urine, profuse white discharge, and rice water or thick paste-like urine seen in gao lin (turbid strangury). Key herbs such as Bi Xie (tokoro), sweetflag rhizome, and lindera root work to expel dampness (drain dampness), clear from the turbid, and warm the kidneys and warm deficiency cold. Typical signs include a pale tongue with white coating and a deep pulse. This formula is commonly used for chronic prostatitis, chronic pyelonephritis, and chronic pelvic inflammatory disease caused by turbid dampness and deficiency cold.
