茯苓（去皮） 泽泻（各一两） 滑石（四两） 白术（炒） 猪苓（去皮） 桂心（炒，各五钱）
石膏 寒水石（各二两）
夏季因饮水过多，导致小便不通利，湿热邪气为患者，此方主治。
三石（滑石、石膏、寒水石）用以清除六腑的热邪，五苓散（茯苓、猪苓、泽泻、白术、桂枝/桂心）用以通利三焦的湿邪。河间（刘完素）的此方，确实是治疗湿热证的简便快捷之法。张子和加入人参、甘草，是因为患者脉象虚弱；加入干葛（葛根），是为了缓解暑热口渴；加入木香，是为了化解湿气。
砂仁 草果仁 乌梅肉 炙甘草（各四两） 扁豆（炒） 干葛（各二两）
夏季体内潜伏热邪，或因饮酒和饮食不当而受伤者，此方主治。
砂仁、草果，用来消除肉食积滞；乌梅、干葛，用来驱除暑热并消除烦闷；扁豆、甘草，用来辅助脾脏并补益胃气。
砂仁 半夏 杏仁 人参 白术 甘草 藿香 木瓜 浓朴 扁豆 赤茯苓
夏季患病出现霍乱转筋（肌肉痉挛）、呕吐泄泻、寒热交替发作、疲倦嗜卧；或伏暑导致的烦闷、小便红赤涩痛，或腹泻或口渴；以及酒醉、孕妇及产后等情况，皆可服用此方。
“六和”意为调和六腑；脾胃是六腑功能的总司，所以凡是六腑不和的疾病，先从调理脾胃入手。这是知务这位医家的见解。芳香药物能开胃窍，所以使用藿香、砂仁；辛味药物能疏散逆乱之气，所以使用半夏、杏仁；淡味药物能通利湿热，所以使用茯苓、木瓜；甘味药物则能止呕，通过利湿调脾，使大小便恢复正常；补虚去弱，能使胃气恢复从而诸病平息。大概脾胃一旦得到调理，则水谷精微向四周布散，五脏经脉并行通畅，虽然全身百骸九窍都能太平无事，何况是六腑呢？
序言说：湿邪有内湿和外湿之分，有阴湿和阳湿之别，有上湿和下湿之异，现在考证七方（大、小、缓、急、奇、偶、复），只是讲述其常规情况，尚未涉及其变化。东南地势低洼潮湿的地区，十个人中有九个患湿病，怎么能穷尽其所有变化呢？这需要在临证时加以仔细考察即可。
Poria (with skin removed) [Fuling] (1 liang), Alisma Rhizome [Zexie] (1 liang), Talcum [Huashi] (4 liang), Atractylodis Rhizoma [Baizhu] (stir-fried), Polyporus [Zhuling] (with skin removed), Cinnamon Twig [Guixin] (stir-fried, 5 qian each for Poria and Alisma; note: text implies specific dosages per herb or grouped, here interpreted as listed).
Gypsum Fibrosum [Shigao], Arsenolite [Han Shui Shi] (2 liang each).
In summer, excessive drinking of water leads to dysuria (difficult urination) and pathogenic damp-heat; this formula is indicated.
The "Three Stones" (Talcum, Gypsum Fibrosum, Arsenolite) clear heat from the Six Fu-organs; Wu Ling San (Five-Ingredient Powder with Poria) promotes diuresis to drain dampness from the Triple Burner. Liu Wan-su's (Hejian) formulation is indeed a simple and effective method for treating damp-heat. Zhang Zihe added Ginseng Radix et Rhizoma [Renshen] and Glycyrrhizae Radix et Rhizoma [Gancao] because the pulse was deficient; he added Kudzu Root [Gegen] to relieve summerheat thirst; he added Aucklandiae Radix [Muxiang] to transform dampness.
Amomi Fructus [Sharen], Tsaoko Fructus [Caoguo Ren], Prunus Mume [Wumei Rou], Glycyrrhizae Radix et Rhizoma [Gancao] (prepared with honey, 4 liang each), Dolichos Lablab Seed [Bian Dou] (stir-fried), Kudzu Root [Gegen] (2 liang each).
In summer, latent heat in the body, or injury caused by alcohol and improper diet; this formula is indicated.
Amomi Fructus and Tsaoko Fructus eliminate meat stagnation; Prunus Mume and Kudzu Root dispel summerheat and remove vexation; Dolichos Lablab Seed and Glycyrrhizae Radix et Rhizoma assist the Spleen and benefit the Stomach.
Amomi Fructus [Sharen], Pinellia Rhizome [Banxia], Apricot Seed [Xing Ren], Ginseng Radix et Rhizoma [Renshen], Atractylodis Rhizoma [Baizhu], Glycyrrhizae Radix et Rhizoma [Gancao], Agastegher Herba [Huoxiang], Papaya [Mugua], Magnolia Bark [Houpo], Dolichos Lablab Seed [Bian Dou], Red Poria [Chifuling].
In summer, patients suffering from cholera-like syndrome with muscle spasms (twisting tendons), vomiting and diarrhea, alternating chills and fever, fatigue and desire to lie down; or summerheat retention causing vexation, red and scanty urine, or diarrhea or thirst; also applicable for drunkenness, pregnancy, and postpartum conditions.
"Liu He" (Six Harmonies) means harmonizing the Six Fu-organs; the Spleen and Stomach are the masters of the Six Fu-organs' functions. Therefore, for any disease of disharmony in the Six Fu-organs, treatment should first focus on regulating the Spleen and Stomach. This reflects the medical philosophy of Zhiwu. Aromatic herbs open the stomach orifices, hence Huoxiang and Sharen are used; pungent herbs disperse rebellious Qi, hence Banxia and Xing Ren are used; bland herbs promote diuresis and drain damp-heat, hence Fuling and Mugua are used; sweet herbs stop vomiting; draining dampness and regulating the Spleen regulates bowel movements and urination; tonifying deficiency and removing weakness restores Stomach Qi, thereby calming various diseases. Once the Spleen and Stomach are regulated, fluids and essence distribute to all parts, and the Five Meridians circulate smoothly. Although the hundred bones and nine orifices will be at peace, how much more so the Six Fu-organs?
Preface: Dampness has internal and external origins, yin and yang characteristics, and upper and lower locations. The current examination of the Seven Formulas discusses only the general principles, not the variations. In the low-lying regions of the Southeast, nine out of ten illnesses are due to dampness; how can one exhaustively describe all variations? This requires careful observation during clinical practice.
