（又名生熟水） 治霍乳吐泻有神功。（药中治霍乱者最多，然有寒热二证，万一误用
，立死不救。仓猝患此，脉候未审，切勿轻投偏热偏寒之剂，惟饮阴阳水为最稳。张子和曰
∶霍乱吐泻，乃风湿 三气合邪也。湿土为风木所克，郁则生热。心火上炎，故吐，吐者
也。脾湿下注，故泻，泻者湿也。风急甚则转筋，转筋者风也。又邪在上焦则吐，在下焦则
泻，在中焦则吐泻交作。）
百沸汤 新汲井水 各半和服。
阴阳不分而扰乱，故上吐下泻而霍乱。饮此辄定者，分理其阴阳，使和平也。
（张景岳）“四”对应五行中的金数，归属于气分。凡是元气不足，或者因饥饿、劳累后感受风寒，或者六脉呈现紧、微、细的脉象，正气不能抵御邪气等证候。必须培补扶助元气，同时兼用解散表邪的方法，才可以保全生命，适宜使用此方主治。如果只知道发散邪气，不固护根本，没有不导致元气先败坏的，诊察时要谨慎小心。
柴胡（一钱至三钱） 人参（根据病情适量） 炙甘草（一钱） 当归（二钱至三钱，腹泻者少用。） 生姜（三片至七片）
（张景岳）“五”对应五行中的土数，归属于脾胃。脾土是五脏的根本，凡是中气不足，而外邪不能消散的情况，此方不可不用。此方与四柴胡饮互为表里，但四柴胡饮仅调理气分，此方则兼培补气血以驱逐外邪，尤其切合时令需求，神效无法详尽描述。凡是伤寒、疟疾、痘疮，都适宜使用。
芍药（炒制） 白术 当归（二钱至三钱） 柴胡（一钱至三钱） 熟地黄（三钱至五钱） 炙甘草（一钱） 陈皮（适量）
若加桂枝二钱
（张景岳）治疗营血虚弱不能化生汗液。凡是真阴不足，外感寒邪难以解除的，这是神效方剂。
当归（一两） 柴胡（五钱） 炙甘草（八分） 或者加生姜三片至七片，或者加陈皮一钱，或者加人参。
（《千金方》）治疗伤寒病后，呕吐呃逆，不能进食。
芦根（一升） 竹茹（一升） 生姜（二两） 粳米（二合）
芦根味甘性寒，能降伏虚火，通利小便。竹茹味甘性寒，能清除胃热，清润燥金。生姜味辛性温，能祛除寒饮，散逆气。
（又名生熟水）治疗霍乱乳食吐泻有神奇功效。（治疗霍乱的药物很多，然而分为寒证和热证两种，万一误用，立即死亡无法救治。仓促间患此病，脉象尚未审察清楚，千万不要轻易投用偏热或偏寒的药剂，只有饮用阴阳水最为稳妥。张子和说：霍乱吐泻，是风、湿、暑三气结合为邪。湿土被风木所克制，郁结则产生热。心火上炎，所以呕吐，吐就是火的表现。脾湿下注，所以腹泻，泻就是湿的表现。风邪急甚则导致转筋，转筋就是风邪所致。另外邪气在上焦则呕吐，在下焦则腹泻，在中焦则呕吐腹泻交替发作。）
百沸汤（刚烧开的水） 新汲井水（刚打出的冷水） 各取一半混合服用。
阴阳之气不分且相互扰乱，所以上吐下泻形成霍乱。饮用此方随即定止的原因，在于分理其阴阳，使其恢复平和。
(Jingyue) "Four" corresponds to the Metal number in the Five Elements and belongs to the Qi level. In cases where Yuan Qi (Original Qi) is insufficient, or after enduring hunger and fatigue followed by contraction of Wind-Cold, or when the six pulses are tight, minute, or fine indicating that Zheng Qi (Upright Qi) cannot overcome the pathogen, it is essential to tonify and assist Yuan Qi while simultaneously dispersing the exterior pathogens. Only then can life be preserved; this formula is suitable for such conditions. If one only knows how to disperse pathogens without addressing the root cause, Yuan Qi will inevitably fail first. One must examine and be cautious.
Chai Hu (Bupleuri Radix) [1-3 qian], Renshen (Ginseng Radix et Rhizoma) [as appropriate], Zhi Gancao (Prepared Licorice Root) [1 qian], Dang Gui (Angelicae Sinensis Radix) [2-3 qian, use less if diarrhea is present], Sheng Jiang (Fresh Ginger Rhizome) [3-7 slices].
(Jingyue) "Five" corresponds to the Earth number and relates to the Spleen and Stomach. Spleen Earth is the foundation of the five zang organs. In cases where Zhong Qi (Middle Jiao Qi) is insufficient and exterior pathogens cannot be dispersed, this formula must not be omitted. This formula has a interior-exterior relationship with Si Chai Hu Yin (Four Bupleurin Decoction), but while Si Chai Hu Yin only regulates the Qi level, this formula also tonifies Blood and Qi to expel exterior pathogens, making it particularly relevant to seasonal changes. Its miraculous effects cannot be fully described. It is suitable for Shang Han (Cold Damage), Malaria, and smallpox/variolae.
Shao Yao (Paeoniae Radix, stir-fried), Baizhu (Atractylodis Macrocephalae Rhizoma), Dang Gui (Angelicae Sinensis Radix) [2-3 qian], Chai Hu (Bupleuri Radix) [1-3 qian], Shu Di Huang (Rehmanniae Radix Preparata) [3-5 qian], Zhi Gancao (Prepared Licorice Root) [1 qian], Chen Pi (Citri Reticulatae Pericarpium) [as needed].
Add Guizhi (Cinnamomi Ramulus) [2 qian] if necessary.
(Jingyue) Treats Ying Deficiency (Deficiency of Nutritive Qi/Blood) preventing the production of sweat. For cases of True Yin insufficiency where exterior Cold pathogens are difficult to resolve, this is a miraculous formula.
Dang Gui (Angelicae Sinensis Radix) [1 liang], Chai Hu (Bupleuri Radix) [5 qian], Zhi Gancao (Prepared Licorice Root) [8 fen].
Alternatively, add Sheng Jiang (Fresh Ginger Rhizome) [3-7 slices], or Chen Pi (Citri Reticulatae Pericarpium) [1 qian], or Renshen (Ginseng Radix et Rhizoma).
(Qianjin Fang) Treats vomiting and hiccups with inability to eat following Shang Han (Cold Damage).
Lugen (Phragmitis Rhizoma) [1 sheng], Zhuru (Bambusae Caulis in Taeniae Succus), Sheng Jiang (Fresh Ginger Rhizome) [2 liang], Jingmi (Oryza Sativa Germ).
Lugen is sweet and cold, subduing Fire and promoting urination. Zhuru is sweet and cold, clearing Stomach Heat and moistening Dryness (Metal). Sheng Jiang is acrid and warm, dispelling Cold-Fluid and dispersing rebellious Qi.
(Also known as Sheng Shu Shui / Raw and Boiled Water) Treats Huoluan (Colic with Vomiting and Diarrhea) and infantile vomiting/diarrhea with miraculous efficacy. (There are many medicines for treating Huoluan, but they are divided into Cold and Hot syndromes. Misuse can lead to immediate death. In sudden onset, before the pulse condition is fully assessed, do not lightly administer formulas that are excessively hot or cold. Drinking Yin-Yang Water is the safest approach. Zhang Zihe stated: Huoluan with vomiting and diarrhea results from the combination of Wind, Dampness, and Summerheat pathogens. Damp Earth is controlled by Wind Wood; stagnation generates Heat. Heart Fire flares upward, causing vomiting (vomiting represents Fire). Spleen Dampness flows downward, causing diarrhea (diarrhea represents Dampness). Severe Wind causes muscle twitching/cramps (twitching represents Wind). Furthermore, pathogens in the Upper Jiao cause vomiting, those in the Lower Jiao cause diarrhea, and those in the Middle Jiao cause alternating vomiting and diarrhea.)
Baifei Tang (Boiling Water) and Xinji Jingshui (Fresh Well Water) are mixed in equal parts and taken orally.
When Yin and Yang energies are indistinct and chaotic, upper vomiting and lower diarrhea occur, constituting Huoluan. Drinking this formula brings relief because it differentiates and harmonizes Yin and Yang, restoring balance.
