车前 木通 大黄 滑石 甘草梢 蓄 瞿麦 栀仁
经曰∶膀胱不利为癃，理宜八正以通之。滑可去着，滑石、车前皆滑也；泻可去实，大黄、草稍、栀仁皆泻
也；通可去滞，瞿麦、 蓄、木通皆通也。若虚人，则大黄不宜用，加生地、桑白皮、苦竹叶，以清疗之。一切
心热冲眼，太阳蕴毒，须与此汤。服后，觉湿热下注，少腹急，小便欲通不通者，加木香化气于中，委顿出矣。
诗曰∶八正车前甘草梢，大黄滑石木通条，山栀 蓄兼瞿麦，郁热奔流小便消。

病症之最急者，莫如风火。风火交战，理宜表里两解。是方防风、麻黄，疏表药也，风热在皮肤者，得之出
汗而泄。荆芥、薄荷，清上药也，风热在巅顶者，得之由涕而泄。大黄、芒硝，通利药也，风热在肠胃者，得之
由秽而泄。滑石、栀子，水道药也，风热在决渎者，得之由溺而泄。风淫于膈，肺胃受邪，石膏、桔梗以清之。
风游于络，伏火随起，赤芍、黄芩、连翘以降之。苦寒恐亡阴，芎 、当归和肝血以养之。辛散恐亡阳，甘草、
白术调胃气以保之。一切暴风客热，服此效。外加菊花、连、羌活、蒺藜，名菊花通圣散，治同。人弱大便不结
者，去硝、黄。天燥热多汗，麻黄亦不宜用。
诗曰∶双解麻黄更大黄，栀荷术芍草芎防，石膏硝滑浑无事，荆桔翘芩用正当。
《内经》说：膀胱气化不利导致小便不通（癃闭），治疗应当用八正散来通利它。滑性药物可以去除黏着之邪，滑石、车前子都具有滑利之性；泻下法可以去除实邪，大黄、甘草梢、栀子仁都具有泻下清热之功；通利法可以去除停滞之邪，瞿麦、萹蓄、木通都具有通利之效。如果是体质虚弱的人，就不宜使用大黄，应加入生地黄、桑白皮、苦竹叶，以清解疗毒之法治疗。凡是心经热邪上冲眼部，或太阳经受蕴积之毒，都必须服用此汤剂。服药后，如果感觉湿热向下注注，少腹部拘急疼痛，小便想排却排不出来的情况，可加入木香以在中焦化气行滞，这样委顿之邪就会排出体外了。
诗云：八正散由车前子和甘草梢组成，配伍大黄、滑石和木通条，再加上山栀、萹蓄和瞿麦，郁热奔流而去，小便自然通畅消除。
防风、大黄、薄荷、芍药、当归、甘草、白术、滑石、石膏、栀子仁、桔梗、连翘、川芎、荆芥、麻黄、芒硝、黄芩。
病症中最紧急的，没有比风火相搏更严重的了。风与火相互交战，治疗应当表里双解。这个方剂中，防风、麻黄是疏散表邪的药物，风热在皮肤层面的，服用后通过出汗而泄出。荆芥、薄荷是清解上焦的药物，风热在头顶部位的，服用后通过鼻涕流出而泄出。大黄、芒硝是通腑泄热的药物，风热在肠胃部位的，服用后通过大便排泄而泄出。滑石、栀子是水液代谢通道的药物，风热在三焦水道部位的，服用后通过小便排泄而泄出。风邪淫溢于膈膜，导致肺胃受邪，用石膏、桔梗来清解。风邪游走于络脉，伏火随之而起，用赤芍、黄芩、连翘来降泄火热。苦寒药物恐怕会损伤阴液，所以用川芎、当归调和肝血以滋养身体。辛散药物恐怕会耗伤阳气，所以用甘草、白术调理胃气以保护正气。凡是暴风客热证，服用此方有效。另外加入菊花、黄连、羌活、蒺藜，名为菊花通圣散，治疗作用相同。人体质虚弱且大便不燥结的，去掉芒硝、大黄。天气干燥炎热多汗时，麻黄也不宜使用。
诗云：双解散包含麻黄和大黄，以及栀子、薄荷、白术、芍药、甘草、川芎、防风，石膏、芒硝、滑石等若无特殊情况则不用，荆芥、桔梗、连翘、黄芩用得恰到好处。
Plantaginis Semen (Cheqianzi), Tectari Radix (Mutong), Rheum Palmatum Rhizoma et Radix (Dahuang), Talcum (Huashi), Glycyrrhizae Radix et Rhizoma caulis (Gancao Shao), Polygoni Avicularis Herba (Bianxu), Diantherae Herba (Qumai), Gardeniae Fructus (Zhiren).
The *Neijing* states: When the Bladder's Qi transformation is obstructed, it results in strangury (Long); the treatment should employ Ba Zheng San to unblock it. Slippery substances remove adherence; Talcum and Plantaginis Semen are slippery. Purgation removes excess; Rheum Palmatum Rhizoma et Radix, Glycyrrhizae Radix et Rhizoma caulis, and Gardeniae Fructus are purgative. Unblocking removes stagnation; Diantherae Herba, Polygoni Avicularis Herba, and Tectari Radix are unblocking agents. If the patient is deficient, Rheum Palmatum Rhizoma et Radix should not be used; instead, add Rehmanniae Radix Preparata (Shengdi), Morus Alba Cortex (Sangbaipi), and Phyllostachys Viridis Caulis (Kuzhuye) to clear and treat with heat-resolving methods. For all cases where Heart Heat rushes upward to the eyes, or when Toxic Heat is accumulated in the Taiyang channel, this decoction must be taken. After ingestion, if one feels Damp-Heat pouring downward, with urgency and pain in the lower abdomen, and a desire to urinate but inability to do so, add Costi Rhizoma (Muxiang) to transform Qi in the middle jiao, thereby expelling the lethargic pathogenic factors.
Poem says: Ba Zheng San consists of Cheqianzi and Gancao Shao, combined with Dahuang, Huashi, and Mutong; adding Zhiren, Bianxu, and Qumai causes turbulent郁热 (stagnant heat) to flow away, eliminating urinary obstruction.
Saposhnikoviae Radix (Fangfeng), Rheum Palmatum Rhizoma et Radix (Dahuang), Menthae Haplocalycis Herba (Bohe), Paeoniae Radix Rubra (Shaoyao), Angelicae Sinensis Radix (Danggui), Glycyrrhizae Radix et Rhizoma (Gancao), Atractodis Macrocephalae Rhizoma (Baizhu), Talcum (Huashi), Gypsum Fibrosum (Shigao), Gardeniae Fructus (Zhiren), Platycodonis Radix (Jiegeng), Forsythiae Fructus (Lianqiao), Ligustici Chuanxiong Rhizoma (Chuanxiong), Schizonepetae Spica (Jingjie), Ephedrae Herba (Mahuang), Mirabilite (Mangxiao), Scutellariae Radix (Huangqin).
Among diseases, none is more urgent than Wind-Fire conflict. When Wind and Fire battle, the treatment principle is to resolve both exterior and interior simultaneously. In this formula, Saposhnikoviae Radix and Ephedrae Herba are exterior-dispersing herbs; for Wind-Heat in the skin, they cause excretion through sweating. Schizonepetae Spica and Menthae Haplocalycis Herba are upper-clearing herbs; for Wind-Heat at the vertex, they cause excretion via nasal discharge. Rheum Palmatum Rhizoma et Radix and Mirabilite are bowel-unblocking herbs; for Wind-Heat in the intestines and stomach, they cause excretion via feces. Talcum and Gardeniae Fructus are water-passage herbs; for Wind-Heat in the Sanjiao waterways, they cause excretion via urine. Wind invading the diaphragm affects the Lung and Stomach; Gypsum Fibrosum and Platycodonis Radix clear this. Wind wandering in the collaterals stirs latent fire; Paeoniae Radix Rubra, Scutellariae Radix, and Forsythiae Fructus descend and reduce it. Bitter-cold substances may damage Yin, so Ligustici Chuanxiong Rhizoma and Angelicae Sinensis Radix harmonize Liver Blood to nourish. Acrid-dispersing substances may damage Yang, so Glycyrrhizae Radix et Rhizoma and Atractodis Macrocephalae Rhizoma regulate Stomach Qi to protect. For all cases of sudden Wind-Kernal Heat, this formula is effective. Adding Chrysanthemi Flos (Juhua), Coptidis Rhizoma (Lian), Notopterygii Rhizoma et Radix (Qianghuo), and Tribuli Fructus (Jili) creates Juhua Tongsheng San, which has the same therapeutic effect. For weak individuals with non-hard stools, remove Mangxiao and Dahuang. In dry, hot weather with excessive sweating, Mahuang should also be avoided.
Poem says: Shuangjie Tang contains Mahuang and Dahuang, Zhiren, Bohe, Baizhu, Shaoyao, Gancao, Chuanxiong, and Fangfeng; Shigao, Mangxiao, and Huashi are omitted unless necessary; Jingjie, Jiegeng, Lianqiao, and Huangqin are used appropriately.
