Bi Xie Fen Qing Yin, also known as Bi Xie Fen Qing San, comes from Yang Shi Jia Cang Fang (Yang’s Family Treasury of Formulas), a time-honored Chinese medicine text. This formula is made of equal parts Bi Xie, Yi Zhi Ren, Shi Chang Pu, and Wu Yao, decocted in water with a pinch of salt.
Its main functions are to warm the kidneys, drain dampness, and clarify turbidity, treating conditions like creamy or cloudy urine (gao lin or bai zhuo) due to cold-dampness in the lower body. Symptoms include frequent, cloudy urination that looks like rice water or thick paste, a pale tongue with white coating, and a deep pulse.

Formula Explanation of Bi Xie Fen Qing Yin
Bi Xie Fen Qing Yin’s herbs are organized according to the Chinese medicine principle of “monarch, minister, assistant, and envoy”:
Monarch Herb: Bi Xie. Bi Xie is the main herb, with warming, dampness-draining, and wind-dispelling properties. It warms kidney yang, clears cold-dampness from the lower body, and relieves frequent, cloudy urination.
Supporting Herbs: Yi Zhi Ren, Wu Yao. Yi Zhi Ren warms the kidneys, boosts yang, secures essence, and reduces urination frequency, enhancing Bi Xie’s warming effects. Wu Yao moves qi, relieves pain, warms the kidneys, and disperses cold, further helping Bi Xie clear cold-dampness and ease urinary symptoms.
Assistant Herb: Shi Chang Pu. Pungent, warm, and aromatic, Shi Chang Pu opens the orifices, clears the mind, drains dampness, and resolves phlegm. It supports Bi Xie in removing damp turbidity and improves mental clarity affected by dampness.
Envoy Herb: Gan Cao. Gan Cao harmonizes the formula, boosts spleen qi, and ensures the warming and draining actions are gentle and balanced.
Pathogenesis Analysis of Bi Xie Fen Qing Yin
Bi Xie Fen Qing Yin targets conditions caused by cold-dampness in the lower body and untransformed damp turbidity.
Cold weakens kidney yang, impairing its ability to transform qi, store essence, and regulate the bladder.

This leads to frequent, cloudy urine resembling rice water or thick paste. Insufficient kidney yang fails to warm and secure, causing internal damp turbidity to worsen urinary frequency and cloudiness.
Effects of Bi Xie Fen Qing Yin
Bi Xie Fen Qing Yin works by warming the kidneys, draining dampness, and clarifying turbidity to relieve symptoms of cold-dampness in the lower body.
Bi Xie warms kidney yang and clears cold-dampness, addressing frequent and cloudy urination. Yi Zhi Ren and Wu Yao enhance this by warming the kidneys, securing essence, moving qi, and dispersing cold. Shi Chang Pu clears damp turbidity and restores mental clarity, aiding in normalizing urination.

Clarifying Turbidity: Beyond warming, Bi Xie drains dampness to “separate the clear from the turbid,” boosting stomach function to clear damp turbidity.
This allows clear yang to rise and turbid yin to descend, restoring normal urination. Shi Chang Pu further supports this by clearing phlegm and opening the orifices, improving symptoms of damp-blocked clarity.
