脉沉为在里，弦为肝脉，是木郁之征也；渴欲饮水，厥阴病则消渴也。白头翁临风偏静，长

木小岑高，得清阳上升之象为臣，是木郁达之，所以遂其发陈之性也；黄连泻君火，可除上
焦之渴，是苦以发之，黄柏泻相火，可止下焦之利，是苦以坚之也。治厥阴热利有二∶初利
用此方，以升阳散火，是谓下者举之，寒因热用法；久利则用乌梅丸之酸以收火，佐以苦寒

Treats heat-type dysentery of the Jueyin (Terminal Yin) channel, characterized by a sensation of heaviness in the anus (tenesmus), a deep and wiry pulse, and thirst with an urge to drink water.
Baitouweng (Radix Pulsatillae, 3 liang) Huanglian (Rhizoma Coptidis) Huangbai (Cortex Phellodendri) Qinpi (Cortex Fraxini) (each 2 liang)
The above four herbs are decocted in water and taken orally.
Ke Yunbo stated: The Three Yin channels (Taiyin, Shaoyin, Jueyin) all present with diarrhea syndromes. Spontaneous diarrhea without thirst belongs to Taiyin disease, indicating cold in the zang organs; spontaneous diarrhea with thirst belongs to Shaoyin disease, due to deficiency in the lower jiao causing heart fire to harass the mind. A deep pulse indicates the pathology is interior; a wiry pulse corresponds to the Liver channel, signifying stagnation of Wood qi; thirst with an urge to drink water is the "xiaoke" (wasting-thirst) symptom associated with Jueyin disease. Baitouweng tends to remain still in the wind and is effective at dispelling wind; used as the sovereign herb, it addresses the Jueyin Wind-Wood nature: when wind moves, Wood shakes and Fire flares up. To calm the fire roaming through orifices, one must first settle the shaking wind. Qinpi, being small but tall, embodies the image of clear Yang ascending; used as the minister herb, it illustrates the principle of "dispersing stagnant Wood," thereby facilitating its generative and renovating nature. Huanglian clears the Minister Fire (Heart Fire), relieving upper jiao thirst, employing bitter flavor to disperse stagnation; Huangbai clears the Minister Fire (Ministerial Fire), stopping lower jiao diarrhea, employing bitter flavor to consolidate Yin. There are two approaches to treating Jueyin heat dysentery: In the initial stage, this formula is used to raise Yang and scatter fire, termed "lifting what has sunk," utilizing a cold treatment for heat conditions (treating heat with cold, potentially involving counter-agency); for chronic dysentery, Wumei Wan (Mume Pill) is used, employing sour flavors to astringe floating fire, assisted by bitter-cold herbs, mixed with warm-tonic herbs. This follows the principle of "opposing and following" the pathology, acting according to what is beneficial, regulating Qi to restore balance.
Treats symptoms such as a deep pulse and cold extremities (jue ni).
