《内经》曰∶岁土不及，风乃大行，民病飧泄霍乱，体重腹痛，筋骨繇复。巢氏《病源》云∶
霍乱吐泻，皆因温凉不调，阴阳混淆，二气相干，致脾胃之间，变而为霍乱。寒气客于脾则
泻，客于胃则吐，亦由饮酒食肉，腥脍生冷过度，或因坐卧湿地，当风取凉，使风冷之气归于
三焦，传于脾胃，脾胃得冷，水谷不消，皆成霍乱。
《原病式》云∶三焦为水谷传化之道路，热气甚则传化失常，而霍乱吐下之证作，火性
燥动故也。
《原病式》云∶霍乱吐下，湿为留饮痞隔，而传化失常，故甚则霍乱吐泻也。
《保命集》曰∶霍乱吐泻不止者，邪在中焦。或因渴而大饮，或因饮而过量，或饥饱过甚，
或湿热内甚，故阴阳不和，是为吐泻。仲景曰∶邪在上焦则吐，邪在下焦则泻，邪在中焦则既吐
且泻，此为急病也。然吐利为急，十死其一二，如挥霍撩乱，而不得吐泻者，此名干霍乱，必死。
法曰∶既有其入，必有所出。今有其入而不得其出者，痞也，塞也。故转筋吐泻者，其气有三∶
曰风，曰火，曰湿。吐为 热也。王氏曰∶炎热暴烁，心之气也。火能炎上，故吐也。泻为湿
也。叔和云∶湿多成五泻。经曰∶湿胜则濡泻。又曰∶风胜则动。筋属肝而应于风木，故脚
转筋，燥急也。《内经》诸转反戾，水液混浊，皆属于热。张仲景治法曰∶热多欲饮水，五苓散；
寒多不饮水者，理中汤。凡觉此证，或先五苓、益元、桂苓甘露饮，乃吐泻之圣药也。慎无与粟
米粥汤，一入于胃，则必死矣。霍乱者，脾胃极损，不能传化，加以粟米，如人欲毙，更加利
刀锯其首，岂有能生者耶？如吐泻多时，欲住之后，宜微以稀粥渐渐养之，以迟为妙。

《黄帝内经》说：如果岁运土气不足，风气就会大肆流行，百姓容易患完谷不化的泄泻和霍乱，身体沉重、腹痛，筋骨拘挛或弛缓。巢元方《诸病源候论》说：霍乱的呕吐和腹泻，都是因为冷暖失调，阴阳混乱，寒热二气相互干扰，导致脾胃之间功能失常，从而演变为霍乱。寒气侵犯脾脏则发生泄泻，侵犯胃腑则发生呕吐；这也是由于饮酒吃肉过多，生冷腥腻食物摄入过量，或者坐卧在潮湿之地，迎风纳凉，使得风冷之气归于三焦，传导至脾胃，脾胃受寒，水谷无法消化，最终都形成霍乱。
刘完素《原病式》说：三焦是水谷传化运行的道路，热气过盛则传化功能失常，于是出现霍乱呕吐和下利的症状，这是因为火的性质燥动所致。
《原病式》又说：霍乱的呕吐和下利，是因为湿气停留成为饮邪，导致气机痞塞阻隔，传化功能失常，所以严重时会出现霍乱吐泻。
张元素《保命集》说：霍乱吐泻不止的，病邪在中焦。可能是因为口渴而大量饮水，或者饮水过量，或者饥饱无常，或者体内湿热严重，导致阴阳不和，从而发生吐泻。张仲景说：邪气在上焦则呕吐，邪气在下焦则泄泻，邪气在中焦则既呕吐又泄泻，这属于急症。然而，剧烈吐泻为急症，十人中可能死一二人；如果突然挥霍撩乱，却想吐吐不出、想拉拉不出，这种名叫“干霍乱”，必定死亡。医法说：既然邪气已经入体，必然有出路。现在邪气进入却无法排出，这就是痞塞。所以出现转筋、吐泻的症状，其致病之气主要有三种：风、火、湿。呕吐属于热证。王冰说：炎热暴烈，是心气的表现。火性炎上，所以发生呕吐。泄泻属于湿证。王叔和说：湿气多会导致五种泄泻。经书说：湿气胜则导致濡泻。又说：风气胜则导致动摇。筋脉归属于肝，对应于风木，所以脚部转筋，干燥紧急。《黄帝内经》中说：各种转筋、反折、屈曲，以及体液浑浊，都属于热证。张仲景的治疗法则说：热多且想喝水的，用五苓散；寒多且不渴的，用理中汤。凡是感觉患有此病，可以先服用五苓散、益元散、桂苓甘露饮，这些是治疗吐泻的神药。千万不要给患者喝粟米粥汤，一旦进入胃中，就必死无疑。霍乱病患者，脾胃极度受损，不能运化，如果再给予粟米，就像人快要死了，再用利刀锯他的头，怎么还能存活呢？如果吐泻时间很长，想要停止之后，应该稍微用稀粥慢慢调养，以缓慢为宜。

The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: When the Earth phase of the annual cycle is deficient, wind qi will prevail excessively. The people may suffer from undigested diarrhea and cholera-like disease (Huoluan), heavy body sensation, abdominal pain, and spasmodic or flaccid movements of the sinews and bones. Chao Yuanfang’s *Zhubing Yuanhou Lun* (Treatise on the Pathogenesis and Manifestations of All Diseases) says: Vomiting and diarrhea in cholera-like disease are caused by improper regulation of warmth and cold, confusion of Yin and Yang, and mutual interference of cold and heat qi. This leads to dysfunction in the Spleen and Stomach, resulting in cholera-like disease. If cold qi invades the Spleen, diarrhea occurs; if it invades the Stomach, vomiting occurs. This is also due to excessive consumption of alcohol, meat, raw/cold/fishy foods, or sitting/lying on damp ground, seeking coolness in the wind. This allows wind-cold qi to return to the Sanjiao (Triple Burner) and transmit to the Spleen and Stomach. The Spleen and Stomach become cold, failing to digest water and grain, all leading to cholera-like disease.
Liu Wansu’s *Yuanbing Shi* (Book on Original Causes of Disease) states: The Sanjiao is the pathway for the transmission and transformation of water and grain. Excessive heat disrupts this transformation, causing symptoms of vomiting and diarrhea in cholera-like disease, due to the dry and agitated nature of Fire.
*Yuanbing Shi* further states: In cholera-like disease with vomiting and diarrhea, dampness remains as retained fluid causing stagnation and obstruction, disrupting transformation. Thus, severe cases result in cholera-like vomiting and diarrhea.
Zhang Yuansu’s *Baoming Ji* (Collection for Preserving Life) states: Cholera-like disease with incessant vomiting and diarrhea indicates pathogenic factors in the Middle Jiao. This may be caused by drinking large amounts of water due to thirst, over-drinking, irregular eating habits, or severe internal damp-heat, leading to disharmony of Yin and Yang, manifesting as vomiting and diarrhea. Zhang Zhongjing said: Pathogens in the Upper Jiao cause vomiting; pathogens in the Lower Jiao cause diarrhea; pathogens in the Middle Jiao cause both vomiting and diarrhea. This is an acute condition. However, violent vomiting and diarrhea are critical, with a mortality rate of one or two out of ten. If there is sudden turmoil but inability to vomit or defecate, it is named "Dry Cholera" (Gan Huoluan), which is invariably fatal. Medical principles state: "Since the pathogen has entered, it must have an exit." If the pathogen enters but cannot exit, it results in stagnation and blockage. Therefore, the qi involved in convulsions, vomiting, and diarrhea stems from three sources: Wind, Fire, and Dampness. Vomiting is attributed to Heat. Wang Bing stated: Violent heat reflects the Qi of the Heart. Fire tends to flare upward, hence vomiting. Diarrhea is attributed to Dampness. Wang Shuhe said: Excess dampness leads to five types of diarrhea. The Classics state: "Excess dampness causes loose stools." Also: "Excess wind causes movement." Sinews belong to the Liver and correspond to Wind-Wood; thus, foot convulsions occur with dryness and urgency. The *Neijing* states: Various convulsions, opisthotonos, flexion, and turbid body fluids all belong to Heat. Zhang Zhongjing’s treatment principles state: For cases with more heat and desire for water, use Wuling San (Five-Ingredient Poria Pill); for cases with more cold and no desire for water, use Lizhong Tang (Regulate the Middle Decoction). Upon sensing these symptoms, one may initially administer Wuling San, Yiyuan San (Benefit Origin Powder), or Guiling Ganlu Yin (Cassia Twig and Poria Sweet Dew Decoction), which are sacred remedies for vomiting and diarrhea. One must strictly avoid giving millet porridge or soup; once ingested into the Stomach, death is certain. Cholera-like disease severely damages the Spleen and Stomach, impairing transformation and transportation. Adding food like millet when the patient is near death is akin to sawing the head of a dying person with a sharp knife—survival is impossible. After prolonged vomiting and diarrhea cease, one should slowly nourish the body with thin porridge, taking care to proceed gradually.
