Treats heat accumulation in the Bladder (Bladder), causing obstruction of the water passages, resulting in strangury with dribbling, astringency, burning pain, or urine resembling bean dregs. Some cases form calculi (stones), some resemble paste or pus, or there is hematuria (blood in urine).

Chifuling (Red Poria) 1 qian 5 fen, Chishao (Red Peony Root) 1 qian, Zhiren (Gardenia Seed) 1 qian, Danggui (Angelica Sinensis), Gancao (Licorice Root) each 1 qian 2 fen. The above five herbs, plus Dengxincao (Juncus Effusus Pith), decocted in water and taken orally.

Qumai (Dianthus Herba), Zhizi (Gardeniae Fructus), Bianxu (Polygoni Avicularis Herba), Dahuang (Rhei Radix et Rhizoma), Mutong (Akebiae Caulis), Huashi (Talcum), Cheqianzi (Plantaginis Semen), Gancao (Licorice Root) each 1 qian, plus Dengxincao (Juncus Effusus Pith) 1 qian, decocted and taken orally (Zhu Zhenheng's formula: add Muxiang (Aucklandiae Radix) 1 qian).

[Note] To unblock and regulate the water passages, transporting them downward to the Bladder (Bladder), this is the function of the Sanjiao (Triple Burner). To receive and store body fluids, and discharge them through qi transformation, this is the function of the Bladder (Bladder). If the water passages fail to transport, internal accumulation leads to wheezing and distension, while external overflow causes skin edema; this is a disease of the Sanjiao (Triple Burner). If reception and storage occur but transformation fails, various types of strangury, astringency, pain, and urinary retention (Linchuang) arise; this is a disease of the Bladder (Bladder). The Classics state: "Yin cannot generate without Yang, and Yang cannot transform without Yin." Therefore, if Yin or Yang is in excess, normal generation and transformation cease. When Yang is excessive and Yin deficient, leading to failure of Bladder qi transformation, it is an indication for Tongguan Wan. When Yin is excessive and Yang deficient, leading to failure of Bladder qi transformation, it is an indication for Shenqi Wan. This concerns diseases arising from qi transformation and yin-yang imbalance. The Classics state: "Deficiency below leads to enuresis." It also states: "Inability of the Bladder to constrain leads to enuresis." The Classics state: "When heat shifts from the Bao (Uterus) to the Bladder, urinary difficulty occurs." It also states: "Imperfection of the Bladder leads to urinary difficulty (Long)." Therefore, deficiency-cold conditions involve the organ's inability to constrain; excess-heat conditions involve excessive constraint preventing expulsion. Bladder qi deficiency, lacking sufficient yuan qi to consolidate, results in the organ failing to constrain and control, leading to leakage diseases; this is an indication for Buzhong Guzhen Tang. Bladder qi heat, obstructed and stagnant, results in excessive constraint preventing expulsion, leading to strangury, astringency, and urinary retention; this is an indication for Bazheng San and Wulin San. This does not solely concern qi transformation, but also diseases arising from deficiency-cold and excess-heat. Both Bazheng San and Wulin San treat strangury, astringency, and urinary retention, but differ in severity. For mild cases, where heat has not yet solidified, although symptoms such as strangury, astringency, red urine, bean-dreg-like urine, stones, paste, blood, and urinary retention are present, the pain is mild and the condition is not urgent. It is appropriate to use Wulin San to simply clear and promote urination. Thus, Zhizi and Fuling are used to clear heat and drain water; Danggui and Shaoyao nourish yin and transform yang; supplemented by Gancao to harmonize yin and yang. The prescription is slightly milder, intending to focus on the anterior orifice. For severe cases, where heat has solidified, not only is the pain intense and the condition urgent, but defecation is also blocked. It is appropriate to use Bazheng San to purge both anterior and posterior orifices. Thus, within the group of herbs targeting the anterior orifice, Dahuang is added to directly attack the posterior orifice (intestines). Zhu Danxi's addition of Muxiang aims to facilitate qi transformation!
