暑证即发为热病，吐泻霍乱，积久后发为疟、痢。霍乱、疟、痢三证，医书各有专科，治法
亦详，故不具载。姑以主方取效速者，附列于下。
暑气入腹，恶心腹痛，上吐下泻，泻如水注，此暑火暴发，升降不利，清浊不分，所泻者
皆五脏之津液，宜速止之。用五苓散，或胃苓汤，利小便清火实脏，甚者桂苓甘露饮。此证
间有夹食积者，医家认为食伤，而用下误矣。亦有谓其秽浊当去者，不知津液暴涸，元气顿
伤，当立止之为上。更有吐泻无物者，为干霍乱，令人立毙，急用炒盐汤或二陈汤探吐之，通则易救。
丹溪亦用理中汤吐，恐热，不敢载方。
二陈汤 化痰利气，干霍乱多煎服之，探吐代瓜蒂散，瓜蒂性峻而损胃，此药利痰而性平。

以上药材切碎，大小如麻豆，每次服用五钱匕，加水一盅半，煮取八分量的药液，去渣后热服，剩下的药渣再煎两次，合并为一次服用，空腹时服用。
暑邪致病即表现为热病，出现呕吐、腹泻、霍乱，日久之后发作疟疾、痢疾。霍乱、疟疾、痢疾这三种病症，医书中各有专门论述，治疗方法也很详细，所以不再全部记载。暂且列出主方中见效快的，附列在下面。
暑气侵入腹部，恶心腹痛，上吐下泻，泻下如水注，这是暑火突然爆发，升降功能不利，清浊不分，所泻出的都是五脏的津液，应当迅速止住。使用五苓散，或者胃苓汤，通过利小便来清火实脏，严重的用桂苓甘露饮。此证间或有夹杂食积的，医生误认为是饮食损伤，而用了攻下的方法，这是错误的。也有人说秽浊之物应当去除，不知道津液突然枯竭，元气顿时受伤，应当立即止住为上策。更有呕吐腹泻无物可出的，称为干霍乱，使人立刻死亡，急用炒盐汤或二陈汤探吐，通畅后容易救治。丹溪也用理中汤催吐，恐怕引起热象，不敢记载方剂。
二陈汤 化痰利气，干霍乱多煎服它，作为瓜蒂散的替代进行探吐，瓜蒂药性峻猛而损伤胃气，此药利痰而药性平和。
广陈皮（去掉白色内皮，一钱五分） 半夏（用姜汁炒，一钱） 云茯苓（去掉外皮，一钱二分） 甘草（三分）
以上药材切碎，用水煎服。

The above herbs are chopped into pieces the size of hemp seeds. Each dose is five qianbi (a small spoon measure). Add one and a half zhong (a cup measure) of water, boil until eight parts remain. Remove the dregs and take hot. The remaining dregs are boiled twice more, combined into one dose, and taken on an empty stomach.
Summerheat pathogenic factors causing disease manifest as febrile diseases, accompanied by vomiting, diarrhea, and cholera-like syndrome. After a long duration, malaria and dysentery may occur. For cholera-like syndrome, malaria, and dysentery, medical texts have specialized chapters and detailed treatment methods, so they are not fully recorded here. Instead, the main formula with rapid efficacy is listed below.
When summerheat qi enters the abdomen, it causes nausea, abdominal pain, upper vomiting and lower diarrhea, with watery stools like a gushing stream. This is due to the sudden outbreak of summerheat fire, leading to dysfunction of ascending and descending mechanisms, and confusion of clear and turbid qi. The discharged fluids are the jinye (body fluids) of the five zang organs, which should be stopped quickly. Use Wuling San (Five-Ingredient Powder with Poria) or Weiling Tang (Stomach and Five-Ingredient Decoction) to promote urination, clear heat, and strengthen the viscera. In severe cases, use Guiling Ganlu Yin (Cassia Twig and Poria Sweet Dew Decoction). Occasionally, this condition involves food stagnation; physicians mistakenly diagnose it as dietary injury and use purgatives, which is erroneous. Some argue that turbid pathogens should be expelled, unaware that jinye has suddenly dried up and yuanqi (primordial qi) is instantly damaged; immediate cessation of symptoms is the best approach. If there is vomiting and diarrhea without any discharge, it is called Gan Huoluan (Dry Cholera), which can cause instant death. Urgently use fried salt water or Erchen Tang (Two-Aged Decoction) to induce vomiting. Once unblocked, rescue is easier. Danxi also used Lizhong Tang (Middle-Warming Decoction) for vomiting, but fearing heat generation, he did not record the formula.
Erchen Tang (Two-Aged Decoction) transforms phlegm and promotes qi circulation. It is frequently decocted for dry cholera to induce vomiting, replacing Gouti San (Melon Seed Powder). Gouti has a harsh nature and damages the stomach, whereas this medicine benefits phlegm resolution with a mild nature.

Chop the herbs, decoct with water, and take orally.
