徐仲光治一痘，八日浆半足，热甚引饮。有用保元汤，而烦渴益甚。余当倍加人参，用人参二两，麦冬两
半，煎成频饮而渴止。此渴甚药轻，不能生津以自救也。

万氏子痘，养脓时，大渴不止，即用前加减方，作大剂代汤饮之，一帖而止。
徐仲光治疗一名患儿，痘疹浆液已充盈，但出现盗汗，这是阴虚的表现。使用保元汤加入浮小麦，治愈了该病。
另一名患儿痘后盗汗，肌肉消瘦且烦躁，这是阳虚的表现。使用补中益气汤加倍用量（原文缺字，通常指黄芪或人参等补气药），加入麦冬，治愈了该病。
曾世荣治疗衡阳侯自牧的次子，五岁，盛夏时节患泄泻，面色垢浊、心烦口渴，耳廓和尾骶部发冷，惊悸不安。诊察其心脉和肝脉浮而洪大，脾脉和肺脉虚而细数。曾说：“面色垢浊、口渴、泄泻，脉象虚细数，这是中暑。惊悸发热，耳廓和尾骶都冷，肝心和心脉洪大，这是痘疮即将发出的征兆。”先服用黄连香薷散，以解除暑毒；接着投用陈氏异功散，再加入附子，以此温实脾土。两天后泄泻停止，三天后痘疹发出，不到十天便痊愈，这是隆暑季节使用附子的功效。（出自《幼幼新书》。）
费建中治疗钟家小女的痘疹，正值炎天受暑，烦扰异常，高热如火烧，痘色干枯发红，多日不起发，渴望喝井水，只给一碗左右，便觉得神清气爽，但求饮不止，最终喝了约两斗，全身微微出汗，精神愉悦才感到舒适，痘疹顿时起发，颜色也红活，最后以清火解毒的方法收功。
徐仲光治疗一名痘疹患者，浆液已足，逐渐变得苍老坚实，应当静养。有人主张脾主结痂，使用异功散加入山药、白芍，结果导致气喘、口渴、身热。这属于实证却用了补剂，导致内外皆热，于是用宽中汤治疗。另外口龈发生疳疮，用清火解毒汤治愈。
另一名患儿痘出八天，浆液已满，身热且渴，咳嗽有痰涎，这是火盛津液枯竭的表现，用白虎汤治愈。
另一名患儿痘起胀，烦渴不已，用寒凉药不能退热，这是“无水”（阴液不足）的表现。应当壮水之主（滋补肾阴），以制约阳光（亢盛的阳热），用六味地黄丸的方料加入麦冬、五味子，多服后治愈。
一名十九岁的患者出痘，第六天痘形匀朗绽突，颜色淡白少神，极度口渴，这是虚弱且津液枯竭。用人参二两，麦冬五钱，水煎慢慢服用。又用补中益气汤加枸杞两剂，保元汤加入冬、芍、归、杞。第九天，浆液充足，口渴停止，用人参一斤治愈。
另一名患儿痘起胀，干枯红紫，根脚坚实，大便干结，烦渴，用黄连解毒汤治愈。
另一名患儿痘第六日起胀，形色顺遂，不进食但引水饮用，这是胃气虚弱，用调脾内托散治疗即愈。也有因毒邪壅滞而不进食、引水饮用的，不可不加以辨别。
徐仲光治疗一名痘疹患者，第八天浆液半足，热甚引水饮用。有人用保元汤，反而使烦渴更加严重。我应当加倍加入人参，用人参二两，麦冬一两半，煎成后频频饮用，口渴停止。这是因为口渴严重而药力轻，不能生津以自救。
另一名患儿痘第九天，空壳无浆，根部血络干枯发红，壮热口渴，给予保元汤反而使口渴更甚。这是肾水枯涸，不能生火。应当壮水之主，用六味地黄丸的方料加入人参、当归、知母、麦冬、枸杞子、菟丝子而治愈。
一名新婚女子出痘，燥热而渴，喝冷冻饮料后即睡，醒来后又不断索饮。当时天气大冷大寒，这也是肾水枯竭，不能制火，属于孤阳绝阴。后来虽然行浆，但两三天后死亡，无阴则阳无以化，正是说的这种情况。（雄按：为什么不投用甘寒壮水的药剂？）
另一名新婚女子出痘，燥热引水饮用，也宜壮水制火，用八味地黄丸的方料加入人参、麦冬、五味子，又用补中益气汤，从而口渴停止，热势减退。
一名患儿痘第七天潮热，口渴自利（自行腹泻），排出臭秽的陈积物，这是脾胃热蒸而下所致，虽然虚但没有寒象，用保元汤这种固中的药剂治愈。如果用药性燥热的药剂，如木香散，灾祸立刻降临。
一名患儿痘浆期，壮热烦渴，舌干口燥。有人怀疑是津液不足，给予保元汤加麦冬，结果热渴更甚，痘色焦紫。此症本属热，但因衣被火炉过暖，用补药反而助长其热。宜用清凉之法，用黄连解毒汤加牛蒡子治愈。
一名患儿痘后热渴能食，便秘尿赤，咽干口燥，这是心经和胃经受邪，用白虎汤治愈。
一名患儿痘后口干舌燥，咽干，食少便调，这是脾胃虚，津液不足。用参苓白术散及人参、冬、甘、术、升、葛、麦冬、花粉、五味、粳米治愈。
一名患儿痘后口渴食少、小便频数，这是饮食损伤胃气，津液不生，所以渴而溺数。用补中益气汤加麦冬、五味子治愈。
一名患儿痘黑陷黄色，不进食，生性好饮酒，顺应其性情给予饮酒，痘疹红绽而愈。
一名患儿冬季出痘，顶陷紫黑，不吃饮食药物，用当归浸酒给他喝，痘疹起胀收功。
一名患儿痘火毒闭阻，形态如同死亡，被移弃到外庭，遇到大雨而苏醒，这是以水来制约火。
一名险痘热壅，索饮不止，连续给予井水数升，口渴停止而痘疹起发。
万密斋治疗邹家的儿子出痘，在养脓阶段，大渴不止。商议用人参麦冬散，对方即按照原方配制。他说：“疮毒太盛，是津液不足的病症，白术燥伤津液，茯苓渗利津液，都是禁忌。”于是将原方去掉茯苓、白术，加入升麻、生地、花粉、知母、淡竹叶，一服药后口渴停止。
Xu Zhongguang treated a child patient whose smallpox pustules were full, but who suffered from night sweats; this indicated Yin deficiency. He used Baoyuan Decoction (Preserve the Origin Decoction) with added Triticum Aestivum Fructum Levisticum (Fuxiaomai), and the disease was cured.
Another child patient suffered from night sweats after smallpox, with emaciation and irritability; this indicated Yang deficiency. He used Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with doubled dosage of [missing character, typically Astragalus or Ginseng], plus Ophiopogon Japonicus Radix (Maidong), and the disease was cured.
Zeng Shirong treated the second son of Marquis Zimu of Hengyang, aged five. In midsummer, he suffered from diarrhea, greasy complexion, irritability, and thirst, with cold ears and sacrum, and palpitations. Palpation revealed the Heart and Liver pulses as floating and surging-large, while the Spleen and Lung pulses were deficient, fine, and rapid. He said: "Greasy complexion, thirst, and diarrhea with deficient, fine, and rapid pulses indicate heatstroke. Palpitations, fever, cold ears and sacrum, and surging-large Heart and Liver pulses indicate that smallpox is about to erupt." First, he administered Huanglian Xiangru San (Coptis and Elsholtzia Powder) to resolve summerheat toxicity; subsequently, he administered Chen's Yigong San (Chen's Extraordinary Efficacy Powder) with added Aconitum Carleilii Radix Preparata (Fuzi) to solidify and warm the Spleen. Diarrhea stopped in two days, eruptions appeared on the third day, and recovery was achieved in less than ten days. This demonstrates the efficacy of using Aconite during peak summerheat. (From *Youyou Xinshu*.)
Fei Jianzhong treated a young girl of the Zhong family for smallpox. It was hot summer, and she had contracted summerheat, suffering extreme irritability, high fever like burning, dry red eruptions that failed to rise for many days, and intense craving for well water. Given only a bowlful, she felt refreshed, but continued to demand more, eventually drinking nearly two dou. After slight sweating over the whole body, her spirit became tranquil and comfortable, eruptions rose immediately, and their color became ruddy and vibrant. Treatment concluded with clearing fire and resolving toxicity.
Xu Zhongguang treated a smallpox case where pustules were full and becoming firm and old; quiet rest was appropriate. Someone argued that the Spleen governs scabbing and prescribed Yigong San with Dioscorea Opposita Rhizoma (Shanyao) and Paeonia Lactiflora Radix Alba (Baishao), resulting in wheezing, thirst, and fever. This was an excess syndrome treated with tonics, causing internal and external heat. It was treated with Kuanzhong Tang (Widen the Middle Decoction). Additionally, gingival canker sores were cured with Qinghuo Jiedu Tang (Clear Fire and Resolve Toxicity Decoction).
In another case, eight days after eruption, pustules were full, with fever, thirst, cough with phlegm, indicating excessive fire depleting fluids. Baihu Tang (White Tiger Decoction) was used and cured it.
In another case, during the swelling stage, there was incessant irritability and thirst. Cooling measures failed to reduce heat, indicating "water deficiency" (Yin fluid insufficiency). The principle of "strengthening the master of water to control sunlight" (nourishing Kidney Yin to subdue hyperactive Yang) was applied using Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) formula with added Ophiopogon Japonicus Radix (Maidong) and Schisandra Chinensis Fructus (Wuweizi). Multiple doses led to recovery.
A nineteen-year-old patient showed uniform, distinct, and protruding eruptions by the sixth day, with pale white color lacking spirit, and extreme thirst, indicating weakness and exhaustion of fluids. Two taels of Ginseng Radix et Rhizoma (Renshen) and five qian of Ophiopogon Japonicus Radix (Maidong) were decocted in water and taken gradually. Subsequently, Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with Lycium Chinense Fructus (Gouqi) for two doses, followed by Baoyuan Decoction (Preserve the Origin Decoction) with Ophiopogon, Paeonia, Angelica Sinensis Radix (Danggui), and Lycium fruit. By the ninth day, when pustules were full and thirst ceased, one jin of Ginseng Radix et Rhizoma (Renshen) was used to achieve cure.
In another case, during the swelling stage, eruptions were dry, red, and scorched purple, with firm roots, constipation, irritability, and thirst. Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity) was used and cured it.
In another case, on the sixth day of swelling, the appearance was favorable, but the patient refused food and drank water continuously, indicating weak Stomach Qi. Tiaopi Neituo San (Regulate Spleen and Support Interior Expulsion Powder) was used for immediate recovery. Note that some cases refuse food and drink due to toxin stagnation, which must be distinguished.
Xu Zhongguang treated a smallpox case where, on the eighth day, half-pustules were full, with severe heat and thirst. Using Baoyuan Decoction made the irritability and thirst worse. I increased the dose of Ginseng Radix et Rhizoma (Renshen) to two taels and Ophiopogon Japonicus Radix (Maidong) to one tael and half, decocted and given frequently, stopping the thirst. This occurred because the thirst was severe and the medication too light to generate fluids for self-rescue.
In another case, on the ninth day, the pustules were empty shells without fluid, roots were dry red, with high fever and thirst. Giving Baoyuan Decoction worsened the thirst. This indicated dried-up Kidney Water unable to generate fire. The principle of strengthening the master of water was applied using Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) formula with added Ginseng Radix et Rhizoma (Renshen), Angelica Sinensis Radix (Danggui), Anemarrhena Asphodeloides Rhizoma (Zhimu), Ophiopogon Japonicus Radix (Maidong), Lycium Chinense Fructus (Gouqi), and Cuscuta Chinensis Semen (Tusizi), leading to recovery.
A newlywed woman developed smallpox with dryness, heat, and thirst. She drank chilled beverages and slept, waking up demanding more drinks. Despite the cold weather, this indicated dried-up Kidney Water unable to control fire, representing isolated Yang and absolute Yin. Although pus formed later, she died within two or three days. Without Yin, Yang cannot transform; this illustrates the point. (Xiong notes: Why not administer sweet-cold formulas to strengthen water?)
Another newlywed woman developed smallpox with dryness, heat, and continuous drinking. Strengthening water to control fire was appropriate. Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) formula with Ginseng Radix et Rhizoma (Renshen), Ophiopogon Japonicus Radix (Maidong), and Schisandra Chinensis Fructus (Wuweizi) was used, along with Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction), stopping thirst and reducing heat.
A child patient had tidal fever on the seventh day of smallpox, thirst, spontaneous diarrhea of foul, accumulated matter, indicating steaming heat in the Spleen and Stomach descending. Although deficient, there was no cold. Baoyuan Decoction (Preserve the Origin Decoction), a middle-solidifying agent, cured it. If hot-drying agents like Muxiang San (Costus Powder) were used, disaster would follow swiftly.
During the pus-forming stage, a child patient had high fever, irritability, thirst, dry tongue, and dry mouth. Suspecting fluid deficiency, someone gave Baoyuan Decoction with Ophiopogon Japonicus Radix (Maidong), but heat and thirst worsened, and eruptions turned scorched purple. The condition was originally heat-based, exacerbated by excessive clothing and heating, making tonics assist the heat. Cooling methods were needed; Huanglian Jiedu Tang (Coptis Decoction for Resolving Toxicity) with Arctii Fructus (Niubangzi) cured it.
After smallpox, a patient had heat, thirst, good appetite, constipation, dark urine, dry throat, and dry mouth, indicating pathogen invasion of the Heart and Stomach meridians. Baihu Tang (White Tiger Decoction) cured it.
After smallpox, a patient had dry mouth and tongue, dry throat, poor appetite, and normal stool, indicating Spleen and Stomach deficiency with insufficient fluids. Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder) combined with Ginseng Radix et Rhizoma (Renshen), Ophiopogon Japonicus Radix (Maidong), Glycyrrhiza Uralensis Radix et Rhizoma (Gancao), Atractylodes Macrocephala Rhizoma (Baizhu), Bupleuri Radix (Chaihu), Bupleuri Radix (Shengma - note: text says Sheng, likely Shengma or Chaihu contextually, here interpreted as lifting herbs), Puerariae Lobatae Radix (Ge), Ophiopogon Japonicus Radix (Maidong), Trichosanthes Kirilowii Radix (Huafen), Schisandra Chinensis Fructus (Wuweizi), and Oryza Sativa (Jingmi) cured it.
After smallpox, a patient had thirst, poor appetite, and frequent urination, indicating dietary injury to Stomach Qi, failure to generate fluids, hence thirst and frequent urination. Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with Ophiopogon Japonicus Radix (Maidong) and Schisandra Chinensis Fructus (Wuweizi) cured it.
A patient with black, sunken, yellow smallpox refused food but loved alcohol. Following his preference, he was given alcohol, and eruptions became red and distinct, leading to recovery.
A winter smallpox case showed sunken, purple-black tops. Food and medicine were refused. Angelica Sinensis Radix (Danggui) infused in wine was given, leading to swelling and recovery.
A critical case of smallpox toxin closure resembled death and was discarded outside. The patient revived upon encountering heavy rain, demonstrating the use of water to control fire.
A critical case with heat stagnation involved incessant drinking requests. Several sheng of well water were given continuously, stopping thirst and allowing eruptions to rise.
Wan Mizhai treated a boy of the Zou family for smallpox. During the pus-nourishing stage, there was incessant great thirst. It was proposed to use Renshen Maidong San (Ginseng and Ophiopogon Powder), which the family prepared according to the original formula. Wan said: "The sores are severe, indicating fluid deficiency. Atractylodes Macrocephala Rhizoma (Baizhu) dries fluids, and Poria cocos (Fuling) leaches fluids; both are contraindicated." Thus, Fuling and Baizhu were removed from the base formula, and Cimicifugae Rhizoma (Shengma), Rehmanniae Radix Recens (Shengdi), Trichosanthes Kirilowii Radix (Huafen), Anemarrhena Asphodeloides Rhizoma (Zhimu), and Lophatherum Gracile Herba (Dan Zhuye) were added. One dose stopped the thirst.
Wan's own son had smallpox with incessant great thirst during the pus-nourishing stage. The aforementioned modified formula was used in large doses as a tea substitute, stopping the thirst after one dose.
