治疗因痰湿积聚引发的疟疾，且没有表证（如恶寒发热）和里证（如便秘腹痛）的患者。
青皮、厚朴、草果、半夏、柴胡、白术、甘草、茯苓、黄芩，水煎服用。
【注释】疟疾属于少阳病（邪在半表半里的病证），如果兼有太阳表证（恶寒发热、头项强痛等），用麻桂各半汤通过发汗法治疗；如果兼有阳明里证（高热、大汗、大渴、脉洪大或便秘等），用大柴胡汤通过泻下法治疗；如果不兼有表里证，或者已经经过发汗、泻下治疗后仍然发作的，应当采用和解少阳的方法治疗。这个方剂是将小柴胡汤（和解少阳的代表方）与四君子汤（益气健脾的基础方）合并使用，既能清解少阳之邪，又能顾护脾胃，所以命名为“清脾饮”。减去人参，是因为患者气不虚；加入气味厚重的草果和厚朴，是为了消除胃中的积滞；加入青皮，配合茯苓、半夏，用来破除痰湿的根本。先贤说：“无痰不成疟，无积不成疟”，此汤正是此理。如果是气虚的患者，仍应加入人参；气实者再加槟榔；热象重者加石膏；汗多者加桂枝，这些都应当根据具体病情灵活斟酌。
治疗痢疾，症见大便赤白脓血，肛门坠胀疼痛（后重窘痛）。
芍药二两、当归五钱、黄连五钱、黄芩五钱、槟榔三钱、木香三钱、甘草三钱。每次服用半两，水煎服用。如果痢疾症状不减，加大黄。
【注释】痢疾多发于夏秋季节，要么是由于外感湿暑邪气，要么是由于内伤生冷食物，导致湿热蕴结酿成。初起时病变在腑（大肠、小肠等六腑），久则传入脏（心、肝、脾、肺、肾五脏）。腑病容易治疗，脏病难治。什么是腑病？病在大肠则从金化，所以大便颜色偏白；病在小肠则从火化，所以大便颜色偏红。因此，红色痢疾多伴有噤口痢（不能进食），因为小肠靠近胃，秽浊之气容易上攻，导致呕吐逆气、无法进食。什么是脏病？传变到心则热势不退，下痢血色如水；传变到肾则痢疾不止，像屋顶漏水一样淋漓不尽；传变到脾则水浆不入，呃逆不食。此汤是治疗初病在腑的方剂。用当归、白芍来调和血液；用木香、槟榔来调理气机，血和则脓血可除，气调则肛门坠胀自然停止；黄芩、黄连燥湿清热；甘草调和脾胃并协调诸药。如果肛门窘迫疼痛严重，或者服药后痢疾不减的，加大黄，这是运用“通因通用”（以通治通）的治疗方法。
Treats malaria caused by phlegm accumulation, where there are no exterior (Taiyang) or interior (Yangming) syndromes.
Qingpi (Exocarpium Citri Reticulatae), Houpo (Cortex Magnoliae Officinalis), Caoguo (Fructus Tsaoko), Banxia (Rhizoma Pinelliae Chienpiao), Chaihu (Radix Bupleuri), Baizhu (Rhizoma Atractylodis Macrocephalae), Gancao (Radix Glycyrrhizae), Fuling (Poria), Huangqin (Radix Scutellariae). Decoct in water and take orally.
[Note] Malaria belongs to Shaoyang disease (disease of the half-exterior and half-interior). If accompanied by Taiyang exterior syndrome (aversion to cold, fever, stiff neck), treat with Mahuang Guizhi Gemi Tang (Ephedra and Cinnamon Twig Half-Dose Decoction) via sweating method; if accompanied by Yangming interior syndrome (high fever, profuse sweating, great thirst, constipation), treat with Daxiehu Tang (Major Bupleurum Decoction) via purgation method; if not accompanied by exterior or interior syndromes, or if it recurs after sweating or purgation, treat according to the harmonizing method for Shaoyang. This formula combines Xiaochaihu Tang (Minor Bupleurum Decoction) and Sijunzi Tang (Four Gentlemen Decoction) to clear Shaoyang heat while protecting the Spleen, hence named "Qingpi Yin" (Clear Spleen Drink). Ginseng is omitted because Qi is not deficient; Caoguo and Houpo, which have strong aromas and flavors, are added to eliminate gastric accumulation; Qingpi is added, assisting Fuling and Banxia, to break the root of phlegm. Ancient sages said: "No phlegm, no malaria; no accumulation, no malaria." This decoction exemplifies this principle. For patients with Qi deficiency, add Ginseng; for those with excess Qi, add Binglang (Areca Seed); for those with excessive heat, add Shigao (Gypsum Fibrosum); for those with profuse sweating, add Guizhi (Cinnamon Twig). These adjustments should be made based on clinical judgment.
Treats dysentery characterized by bloody and white pus-like stool, tenesmus, and urgent pain.
Shaoyao (Radix Paeoniae Alba), 2 liang; Danggui (Radix Angelicae Sinensis), 5 qian; Huanglian (Rhizoma Coptidis), 5 qian; Huangqin (Radix Scutellariae), 5 qian; Binglang (Semen Arecae), 3 qian; Muxiang (Radix Aucklandiae), 3 qian; Gancao (Radix Glycyrrhizae), 3 qian. Take 0.5 liang per dose, decoct in water and drink. If dysentery does not subside, add Dahuang (Radix et Rhizoma Rhei).
[Note] Dysentery arises in summer and autumn, either due to external damp-heat and summerheat pathogens or internal injury from raw and cold foods, leading to fermentation of dampness and heat. Initially, the pathology is in the Fu organs (intestines), which are easier to treat; later, it transmits to the Zang organs, which are difficult to treat. What are Fu organ diseases? Disease in the Large Intestine transforms according to Metal, so the stool color is white; disease in the Small Intestine transforms according to Fire, so the stool color is red. Therefore, red dysentery often presents as Jin Kou Li (anorexic dysentery/cannot eat), because the Small Intestine is close to the Stomach, allowing turbid qi to attack upward, causing vomiting and inability to eat. What are Zang organ diseases? Transmission to the Heart results in unceasing heat and bloody watery stool; transmission to the Kidney results in unremitting dysentery like a leaking roof; transmission to the Spleen results in inability to ingest fluids, hiccups, and anorexia. This decoction treats early-stage disease located in the Fu organs. Danggui and Baishao (White Peony Root) are used to regulate Blood; Muxiang and Binglang are used to regulate Qi. When Blood is harmonized, pus and blood can be eliminated; when Qi is regulated, tenesmus will cease naturally. Huangqin and Huanglian dry dampness and clear heat. Gancao harmonizes the Middle Jiao and moderates the properties of other herbs. If tenesmus and pain are severe, or if dysentery does not subside after taking the medicine, add Dahuang. This applies the therapeutic principle of "treating obstruction with draining methods" (using purgatives to treat diarrhea/dysentery).
