常病常法易知，变病变法难详。
上一段论伤寒杂证，从面至足及眠，逐一详审，以便问证云。
神志安定，言语行动迅速，胡言乱语，无故发笑，严重时登高歌唱，脱衣奔跑，翻越墙垣屋顶，不感到饥饿也不愿躺卧。这都是因为发汗或攻下治疗不当，导致阳气亢盛至极，阴气突然虚弱，非用剧烈的催吐或泻下法不能治愈。伤寒病四五日，身体发热烦躁，无法出汗而发狂的，属于表里俱热，可用三黄石膏汤、双解散。伤寒病六七日，高热胸满大便闭塞，脉象实数而发狂的，用大承气汤加黄连。阳毒邪气暴盛而发狂，多伴有干呕，面红，出现斑疹咽喉疼痛，腹泻排出黄红色粪便，高热且无汗的，用葶苈苦酒汤。咽喉疼痛吐出脓血的，用阳毒升麻汤。潮热严重的，用栀子仁汤。潮热伴有大便闭塞的，用升麻葛根汤加大黄，或者三黄汤。出现斑疹不可使用泻下法的，单用草龙胆一味药，水煎服用。狂奔乱走的，用瓜蒂散催吐痰涎。时行热毒引发发狂的，用黑奴丸。通用的方法有水渍法、火劫法、王氏玄明粉。凡是发狂见到阳证阳脉的为顺证，见到阴证阴脉以及舌体卷缩、睾丸上缩的即刻死亡。
嗜睡多因阴气盛，白天睡觉也不厌倦；
伤寒邪气传入阴经则多嗜睡，昏昏沉沉闭着眼睛的，是因为阴主闭合；沉默寡言不想说话的，是因为阴主安静。有太阳病证候在体表已经解除而精神即将恢复的，如果伴有胸满胁痛鼻干，能够出汗的，用小柴胡汤；脉浮的，用羌活冲和汤；冬季发病的，用麻黄汤。有阳明热邪伏于体内而嗜睡的，用小柴胡汤。少阴病脉象沉细，自利想吐且口渴多睡的，用四逆汤加人参、茯苓来益阴回阳。或者是热病出汗后，脉象沉细，身体寒冷，起初感觉安静，逐渐昏沉，喜欢躺卧不省人事，也应紧急给予四逆汤，使四肢温暖，否则，会有熟睡中死亡的。合病目合则汗出，风温病常缠绵不愈，狐惑病精神恍惚，治疗方法见各相关条目。只有发汗或攻下后酣睡的，是正气已经恢复，不需要用药。
失眠多因阳气盛，夜间卧床不得安宁。
或者整夜烦躁扰攘，或者昼夜清醒无法入睡。未经过发汗或攻下而未眠的，属于阳明初证的，用葛根解肌汤；病位在里属于心神不清的，用大承气汤。已经经过发汗或攻下而未眠的，津液干枯，热盛阴虚，胃气不和。太阳病发汗过多，躁动不得眠，想要喝水的就会痊愈。如果脉浮且口渴，小便困难的，用五苓散。发汗、催吐、攻下后，心中懊恼不得眠的，用栀豉汤。昼夜不得眠的，用酸枣仁汤。错语、干呕、不得眠的，用解毒汤。谵语，小便淋涩，烦躁少睡的，用白虎汤加山栀。夹杂瘀血的，用犀角地黄汤。
少阴病下利且口渴，或者因为攻下后不得眠的，用猪苓汤。少阴病二三日，心烦不得眠的，用黄连鸡子汤。攻下后阳气虚弱，脉沉没有表证，夜间安静白天烦躁不得眠的，宜用古姜附汤，或者四逆汤加茯苓。出汗多的，用小建中汤。伤寒病愈后不得眠的，是阴气尚未恢复，用栀子乌梅汤，或者温胆汤加竹茹；虚证的，用十味温胆汤。精神恍惚的，用朱雀丸，古法治疗失眠的，单用熟酸枣散；多睡的，单用生酸枣散也好。
常规疾病常规治法容易知晓，变化疾病变化治法难以详尽。
上一段论述伤寒杂证，从面部到足部及睡眠情况，逐一详细审察，以便询问病情。
Stable spirit, rapid speech and movement, delirious talk and laughter, in severe cases climbing high to sing, discarding clothes and running, scaling walls and roofs, without hunger or desire to lie down. All these result from improper sweating or purging therapies, leading to extreme hyperactivity of Yang Qi (Yang Energy) and sudden deficiency of Yin Qi (Yin Energy); only drastic emesis or purging can stop it. In Shanghan (Cold Damage) disease on the fourth or fifth day, with body heat, irritability, inability to sweat, and mania, this indicates heat in both exterior and interior; Sanhuang Shigao Tang (Three-Yellow Gypsum Decoction) or Shuangjie San (Double-Release Powder) may be used. On the sixth or seventh day, with high fever, chest fullness, constipation, excess-rapid pulse, and mania, Da Chengqi Tang (Major Order the Qi Decoction) added with Huanglian (Coptidis Rhizoma) is indicated. For acute Yang Toxin (Yang Du) causing mania, often accompanied by dry heaving, red face, macules, sore throat, yellow-red diarrhea, high fever, and anhidrosis, Tingli Kujiu Tang (Descurainia Vinegar Decoction) is used. For sore throat with pus and blood expectoration, Yangdu Shengma Tang (Yang Toxin Cimicifugae Decoction) is prescribed. For severe tidal fever, Zhizi Ren Tang (Gardenia Seed Decoction) is used. For tidal fever with constipation, Shengma Gegen Tang (Cimicifugae and Puerariae Decoction) added with Dahuang (Rhei Radix et Rhizoma), or Sanhuang Tang (Three-Yellow Decoction), may be used. For macules where purging is contraindicated, Caolongdan (Dragon's Beard Gentian) alone, decocted in water, is taken. For manic running, Gouti San (Melon Pedicle Powder) is used to induce vomiting of phlegm. For epidemic heat-toxin causing mania, Heinu Wan (Black Slave Pill) is administered. General methods include water immersion therapy, fire coercion therapy, and Wangshi Xuanmingfen (Wang's Purified Mirabilite). Generally, mania presenting with Yang syndrome and Yang pulse is favorable; presenting with Yin syndrome and Yin pulse, or with tongue retraction and testicular retraction, indicates immediate death.
Excessive sleepiness is due to Yin excess, with no aversion to sleeping during the day;
When Shanghan pathogen transmits to the Yin meridians, there is excessive sleepiness; drowsy with eyes closed indicates Yin governs closure; silent and unwilling to speak indicates Yin governs stillness. If Taiyang (Greater Yang) exterior symptoms have resolved and spirit is recovering, but chest fullness, hypochondriac pain, and dry nose persist, if sweating occurs, Xiaochaihu Tang (Minor Bupleurum Decoction) is used; if the pulse is floating, Qianghuo Chonghe Tang (Notopterygii Harmonizing Decoction) is used; in winter, Mahuang Tang (Ephedra Decoction) is used. If Yangming (Bright Yang) heat is latent internally causing drowsiness, Xiaochaihu Tang is used. If Shaoyin (Lesser Yin) presents with deep-thready pulse, spontaneous diarrhea, desire to vomit, thirst, and sleepiness, Sini Tang (Frigid Extremities Decoction) added with Renshen (Ginseng Radix et Rhizoma) and Fuling (Poria) is used to nourish Yin and restore Yang. Or after a febrile disease sweats, if the pulse is deep-thready, body cold, initially feeling calm but gradually becoming comatose and preferring to lie down unconscious, Sini Tang should be urgently administered to warm the limbs; otherwise, death in deep sleep may occur. In combined diseases where closing eyes causes sweating, Fengwen (Wind-Warmth) often lingers unresolved; Huhuo (Huoxue Disease) involves mental恍惚 (fluctuation/unsteadiness); treatments are found in respective sections. Only deep sleep after sweating or purging indicates recovery of Zheng Qi (Upright Qi), requiring no medication.
Insomnia is due to Yang excess, with restlessness at night.
Or tossing all night, or remaining awake day and night without sleep. Insomnia without prior sweating or purging belongs to initial Yangming stage; Gegen Jiexi Tang (Pueraria Muscle-Releasing Decoction) is used. If internal and belonging to unclear Shen (Spirit/Mind), Da Chengqi Tang is used. Insomnia after sweating or purging results from dry Jin Ye (Body Fluids), excess heat, Yin deficiency, and disharmony of Stomach. Excessive sweating in Taiyang disease causes restlessness and insomnia; if thirsty, recovery follows. If pulse is floating with thirst and difficult urination, Wuling San (Five-Ingredient Powder with Poria) is used. After sweating, vomiting, or purging, if Ao'ao (oppressive discomfort) prevents sleep, Zhichi Tang (Gardenia and Soybean Decoction) is used. Day-and-night insomnia is treated with Suanzaoren Tang (Ziziphus Seed Decoction). Erratic speech, dry heaving, and insomnia are treated with Jiedu Tang (Detoxification Decoction). Delirium, dysuria, irritability, and little sleep are treated with Baihu Tang (White Tiger Decoction) added with Shanzhi (Gardeniae Fructus). With blood stasis, Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) is used.
Shaoyin diarrhea with thirst, or insomnia after purging, is treated with Zhuling Tang (Polyporus Decoction). Shaoyin disease for two to three days with heart vexation and insomnia is treated with Huanglian Jizi Tang (Coptis and Egg Yolk Decoction). After purging, Yang deficiency with deep pulse and no exterior signs, quiet at night but vexed during day preventing sleep, requires Gu Jiangfu Tang (Ancient Ginger and Aconite Decoction) or Sini Tang added with Fuling. With profuse sweating, Xiao Jianzhong Tang (Minor Construct the Middle Decoction) is used. Post-Shanghan insomnia indicates incomplete recovery of Yin Qi; Zhizi Wumei Tang (Gardenia and Mume Fruit Decoction) or Wendan Tang (Warm Gallbladder Decoction) added with Zhuru (Bambusa Caulis in Taenia) is used; for deficiency, Shiwei Wendan Tang (Ten-Ingredient Warm Gallbladder Decoction) is used. For mental fluctuation, Zhuque Wan (Vermilion Bird Pill) is used. Ancient methods for insomnia use Dan Shu Suan Zao San (Single-Roasted Ziziphus Seed Powder); for hypersomnia, Dan Sheng Suan Zao San (Single-Fresh Ziziphus Seed Powder) is also good.
Common diseases and common methods are easy to know; changed diseases and changed methods are hard to detail.
The previous section discussed Shanghan miscellaneous syndromes, examining from face to feet and sleep patterns in detail, to facilitate inquiry into symptoms.
