热邪内外熏蒸，遇风寒辄与内热相拒而不得入内，热为风寒所闭而不得出，毒瓦斯壅于肌表，故形如痕点，
其色青紫者有之，宜用生地、紫草、凌霄花、丹皮、玄参、连翘、黄芩、红花、全
蝎、石膏、川连，如大便秘结加生军。
连出不收者，热毒太甚也。不能一时发透，宜重表之。如回后用化斑解毒汤治之（玄参、知母、升麻、
力子、人中黄、连翘、石膏），大便闭结加生军、生地、红花、紫草。
牙根血出胃火并，宜投天麻枳花粉，麦冬生地黄连入，重用石膏生条芩。此因积热毒火入胃，宜用清胃
饮、凉膈散（薄荷、山栀、连翘、桔梗、黄芩、生地、甘草、川连、升麻、丹皮、石膏）。
齿颊肿痛口流涎（宜用川芎、防风、石膏、黄连、玄参、黄芩、甘草、牛蒡子），不投阳剂痛连绵。
疹后红斑作痒，疹后发热一二日，红斑作痒遍身散出，愈爬愈痒，状如细粟，或成云片，一涌而出，此因
回后不禁辛辣、油腻之味，放心纵食，以致风热寒湿之气外感而成也。急宜三花斑汤加防风、黄连，以除
风热，免生泻利。倘泻痢日久不已，此余毒移入于大肠也，切勿妄投止涩，以致内毒上攻，转成呕吐，噤
口不食，而莫可疗生也。如滑泄不止，或下鲜血，或如屋漏尘水者，急服三黄汤加槟榔、枳壳、六一散，治之可望愈矣。
Heat pathogens steaming internally and externally, when encountering wind-cold, repel the internal heat and cannot enter; the heat is blocked by wind-cold and cannot exit. Toxic qi stagnates at the muscle surface, resulting in macule-like spots on the skin. Some may appear cyanotic or purplish. It is appropriate to use Shengdi (Rehmanniae Radix), Zicao (Arnebiae Radix), Lingxiaohua (Campsis Grandiflora Flos), Danpi (Moutan Cortex), Xuanshen (Scrophulariae Radix), Lianqiao (Forsythiae Fructus), Huangqin (Scutellariae Radix), Honghua (Carthami Flos), Quanxie (Buthus), Shigao (Gypsum Fibrosum), Chuanlian (Coptidis Rhizoma). If constipation occurs, add Shengjun (Rhei Radix et Rhizoma).
Continuous eruption without receding indicates excessive heat toxicity. If it fails to erupt thoroughly at once, heavy exterior-releasing methods should be employed. After the rash subsides, Huaban Jiedu Tang (Macula-Resolving and Toxin-Clearing Decoction) should be used (composition: Xuanshen, Zhimu, Shengma, Zhizi [Zhi Shi], Renzhonghuang, Lianqiao, Shigao). If constipation persists, add Shengjun, Shengdi, Honghua, and Zicao.
Bleeding from the gums indicates blazing stomach fire. Tianma (Gastrodiae Rhizoma), Zhike (Aurantii Fructus), Huafen (Puerariae Radix), Maidong (Ophiopogonis Radix), Shengdihuang (Rehmanniae Radix Recens), and Huanglian (Coptidis Rhizoma) are suitable, with heavy doses of Shigao and Shengtiaoxin (Huangqin). This results from accumulated heat and toxic fire entering the stomach. Qingwei Yin (Stomach-Clearing Drink) and Liangge San (Cooling Diaphragm Powder) are appropriate (composition: Bohe, Shanzhi, Lianqiao, Jiegeng, Huangqin, Shengdi, Gancao, Chuanlian, Shengma, Danpi, Shigao).
Swelling and pain in the teeth and cheeks with salivation flowing from the mouth corners (suitable for using Chuanxiong, Fangfeng, Shigao, Huanglian, Xuanshen, Huangqin, Gancao, Niubangzi) require avoiding yang-tonifying agents, otherwise pain will persist continuously.
After the rash, red macules appear with itching. One to two days after the rash, red macules itch all over the body as they spread out. Scratching increases the itchiness; the appearance resembles fine millet seeds or cloud-like patches erupting suddenly. This is caused by consuming spicy and greasy foods without restraint after the rash subsides, leading to external contraction of wind-heat and cold-dampness. Urgently apply Sanhua Ban Tang (Three-Flower Macula Decoction) added with Fangfeng and Huanglian to dispel wind-heat and prevent diarrhea/dysentery. If diarrhea/dysentery persists for a long time, this indicates residual toxins shifting to the large intestine. Do not recklessly administer astringents, which may cause internal toxins to attack upward, turning into vomiting, inability to eat due to locked mouth (Jinkou), and untreatable conditions. If slippery diarrhea continues unceasingly, or if fresh blood is passed, or if stools resemble dripping roof water or turbid liquid, urgently take Sanhuang Tang (Three-Yellow Decoction) added with Binglang (Arecae Semen), Zhike (Aurantii Fructus), and Liu Yi San (Six-to-One Powder); treatment offers hope for recovery.
