热厥也。视其口，则舌有红斑一，黑斑三。语众曰∶此非热而何？遂大寒凉之剂投之，一服得寐
而渴止。诘朝四服，痘色微红有神，九日而起。（《太函集》。）
徐仲光治疗一个患儿，出痘之后，午饭后出现发热，面色发红，胡言乱语、狂躁颠狂，这是火邪从虚损处发作所致，使用保元汤加入当归、川芎、黄连而痊愈。
另一个患儿出痘后，身体发热但食欲减退，面色萎黄、肌肉消瘦，右脉沉滑。虽然属于内伤，但脾胃虚弱，应当先调理而后消导，使用六君子汤加入山楂、青皮而痊愈。
第三个患儿痘痂脱落后进食正常但便秘，身体发热、口渴，这是胃中有积热所致，拖延则病情变化。使用三黄丸、清胃汤通利大便而痊愈。
第四个患儿出痘后，正值夏季出现痞满、燥热，医生用巴豆攻下，心下痞闷稍缓解，但肠道干燥腹痛，腹泻如烂鱼脑状，勉强进食即呕吐，痞闷嗳气不止，足部及肘部疼痛，舌质红、小便涩滞，这是损伤了元气，又因热药再次伤害，导致阴液亡失而阳气独存。
第五个患儿出痘后因伤食，过度使用克伐药物，导致面色萎黄、食欲不振，午后潮热，使用清热剂后，更加严重出现泄泻。这是中气不足，使用六君子汤、补中益气汤即痊愈。
第六个患儿出痘后身体发热烦躁，面色红、嘴唇赤，惊厥抽搐，这是热邪伤风所致。由于衣被太暖，或靠近火源，积温而成热，热极生风。使用犀角地黄汤合导赤散而痊愈。
万密斋治疗徐氏之子，出痘后发热。有人用小柴胡汤、竹叶汤、黄连解毒汤，都不见效。于是给予保元汤加入当归、炒黑干姜，一服药后热退。
费建中治疗沈氏之女，周岁，身体发热如火烧，出汗如雨，两目彷徨不定，如同畏惧刀锯，使用大黄四分，黄连三分，石膏二钱，佐以青皮、木通、山楂、丹皮、蝉蜕，连服两剂。次日，神色安定，发出少量痘疹，磊落分明。又服两剂，热退神爽，痘疹稀疏且滋润。再用中和之剂，八日痊愈。
吴桥治疗汪一龙，幼年患痘，病程第七天，痘多而不突起，四肢皆凉，痘色如浮萍，干红枯紫，极度口渴，饮用茶水，每日数十升，水泻不禁。众医都认为是寒证，依次使用木香异功散、独参汤补益，随后排出凝结的血块数枚，众医辞去。吴桥到后，认为这是火症，众人都不以为然。都说：身凉饮水多，且水泻不止，即使有热，也无大碍。吴桥说：水泻是挟热；身凉是热厥。看他的口，舌上有红斑一处，黑斑三处。对众人说：这难道不是热证吗？于是投以大寒凉之剂，一服药后得睡且渴止。第二天早上四服药后，痘色微红有神，第九天痘起。（《太函集》。）
Xu Zhongguang treated a child who, after smallpox, developed fever after noon, with a red face, delirium, and mania. This was fire arising from deficiency. He used Baoyuan Tang (Preserve the Origin Decoction) added with Danggui (Angelicae Sinensis Radix), Chuanxiong (Ligustici Chuanxiong Rhizoma), and Huanglian (Coptidis Rhizoma), resulting in recovery.
Another child, after smallpox, had reduced body heat and appetite, sallow complexion, and emaciation, with a deep and slippery pulse on the right side. Although it was an internal injury, the Spleen and Stomach were deficient; thus, regulation should precede elimination. He used Liujunzi Tang (Six Gentlemen Decoction) added with Shanzha (Crataegi Fructus) and Qingpi (Aurantii Fructus Pericarpium Viride), resulting in recovery.
A third child, after the scabs of smallpox fell off, could eat but suffered from constipation, body heat, and thirst. This was accumulated heat in the Stomach; if delayed, complications would arise. He used Sanhuang Wan (Three Yellows Pill) and Qingwei Tang (Clear the Stomach Decoction) to promote purgation, resulting in recovery.
A fourth child, after smallpox, experienced fullness and dry heat in summer. The physician used Baiduo (Crotonis Fructus) to purge, which slightly relieved epigastric fullness but caused dry intestines, abdominal pain, diarrhea resembling rotten fish brains, vomiting upon forced eating, persistent fullness and belching, pain in the feet and elbows, red tongue, and difficult urination. This indicated damage to Yuan Qi (Original Qi), further injured by hot herbs, leading to the loss of Yin and the survival of Yang alone.
A fifth child, after smallpox, suffered from food stagnation. Overuse of harsh draining medicines led to sallow complexion, poor appetite, afternoon tidal fever, and worsening diarrhea when cooling agents were used. This was due to insufficient Middle Qi (Middle Jiao Qi). He used Liujunzi Tang (Six Gentlemen Decoction) and Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction), resulting in recovery.
A sixth child, after smallpox, had body heat, irritability, red face, red lips, and convulsions. This was wind generated by extreme heat due to excessive warmth from clothing or proximity to fire. He used Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) combined with Daochi San (Direct Flowing Powder), resulting in recovery.
Wan Mizhai treated the son of the Xu family, who had fever after smallpox. Xiao Chaihu Tang (Minor Bupleurum Decoction), Zhuye Tang (Bamboo Leaf Decoction), and Huanglian Jiedu Tang (Coptis Detoxification Decoction) were ineffective. He prescribed Baoyuan Tang (Preserve the Origin Decoction) added with Danggui (Angelicae Sinensis Radix) and Chaohei Ganjiang (Stir-fried Blackened Zingiberis Rhizoma). One dose eliminated the fever.
Fei Jianzhong treated a one-year-old girl of the Shen family, who had burning fever, profuse sweating like rain, restless eyes, and fear as if facing knives and saws. He used Dahuang (Rhei Radix et Rhizoma) 4 fen, Huanglian (Coptidis Rhizoma) 3 fen, and Shigao (Gypsum Fibrosum) 2 qian, assisted by Qingpi (Aurantii Fructus Pericarpium Viride), Mutong (Akebiae Caulis), Shanzha (Crataegi Fructus), Danpi (Moutan Cortex), and Chantui (Cicadae Periostracum). After two doses, her spirit settled, and a few distinct spots appeared. After another two doses, the heat subsided, she felt refreshed, and the lesions were sparse and moist. With harmonizing agents, she recovered in eight days.
Wu Qiao treated Wang Yilong, who contracted smallpox in childhood. On the seventh day, the lesions were numerous but did not rise, limbs were cold, and the lesions resembled floating duckweed, dry, red, withered, and purple. He was extremely thirsty, drinking dozens of sheng of tea water daily, with uncontrollable watery diarrhea. All physicians considered it a cold syndrome and administered Muxiang Yigong San (Aucklandia and Four Gentlemen Powder) and Dushen Tang (Single Ginseng Decoction) for tonification. Subsequently, several clots of blood were passed, and the physicians left. Wu Qiao arrived and diagnosed it as a fire syndrome, which others disputed. They said: "Cold body, high water intake, and continuous diarrhea indicate that even if there is heat, it is not harmful." Wu Qiao said: "Watery diarrhea indicates accompanying heat; cold body indicates heat jue (reversal)." Examining his mouth, he saw one red spot and three black spots on the tongue. He told the crowd: "How can this not be heat?" He then administered strong cold-cooling agents. After one dose, he slept, and thirst ceased. By the next morning, after four doses, the lesions became slightly red and vibrant. On the ninth day, they rose. (Taihan Ji.)
