邪热传里，不经发汗、吐、下则为烦热，与发热似同而异。经曰∶病患烦热，汗出则解。如未
作膈热，但当和解微热而已。若心下满而烦，则有吐下之异，宜别其证之虚实而为剂之轻重也。先
烦而悸者，为实。先悸而烦者，为虚。虚烦而心中欲呕吐郁闷之状。
太阳病，心烦自汗，小便数者，不可与桂枝汤，宜芍药甘草汤。服桂枝汤后，出汗后烦渴者，
脉洪大，白虎加人参汤。
阳明病，心烦喜呕，壮热往来，心下悸，小便不利，小柴胡汤加茯苓。伤寒二三日，心中悸而
烦，小建中汤。
发汗后解，半日许复烦，脉浮数者，可更发汗，桂枝汤。
衄而烦渴者，饮则吐水，五苓散；不愈，竹叶石膏汤。
下后昼烦夜静，不渴不呕，无表证，脉微沉，干姜附子汤。若懊 ，栀子豆豉汤。
若发汗，若下之，病仍不解而烦躁者，茯苓四逆。大下后六七日不大便，不解，腹满痛者，有
燥屎，大承气汤。吐、汗、下后虚烦，心下痞满，气上冲胸，头眩，身为振摇，茯苓桂枝白术甘草
汤。
肾伤寒，表里无热，但烦愦，不欲见光明，有时腹痛，其脉沉细，四逆汤。
烦为扰乱而躁为愤怒，躁为先烦而渐至躁也。伤寒烦躁，则有阴阳虚实之别。心热则烦，阳实阴
虚。肾热则躁，阴实阳虚。烦则热之轻，躁则热之甚也。有邪在里而烦躁者，有不烦便作躁闷者，此
为阳盛隔阴，欲于泥水中卧，饮水不得入口也。
其或结胸证具而烦躁，吐利四逆而烦躁，下利发热，厥逆，烦躁不得眠，
恶寒燥挛，脉不出而躁者，皆为不可治也。
太阳中风，脉浮紧，热而恶寒，身疼痛，不汗出而烦躁，大青龙汤。得病二三日，脉弱，无太阳
证，柴胡汤。
证烦躁，心下硬，能食，小承气汤微和之。心中悸而烦躁者，小建中汤。
恶风自汗，脉濡弱而烦躁者，皆用此法。
但发热六七日，渴欲饮水者，五苓散。无热，但狂言烦躁者，五苓散，水调服探吐之。
阳明病，不大便，绕脐痛，烦躁，承气汤下之。
少阳吐利厥逆，烦躁欲死，吴茱萸汤。
厥逆，脉沉自利，烦躁不得眠，黄连鸡子汤、黄连阿胶汤。
下后复发汗，昼则烦躁不得眠，夜而安静，不呕不渴，无表证，脉沉微，身无大热，干姜附子
汤。发汗，若下之，病仍在不去，烦躁者，茯苓四逆汤。
阴极发躁，或阴毒火邪，投热药反剧者，不可用凉药，躁甚仍与热剂，用四逆汤辈。
邪热传入体内，如果没有经过发汗、催吐或泻下等治疗，就会出现烦热症状，这与发热看似相同实则不同。《内经》说：患者出现烦热，出汗后就会缓解。如果尚未形成膈间热证，只需通过和解法轻微退热即可。如果心下部胀满且心烦，则治疗方法有催吐和泻下的区别，应当辨别病证的虚实来决定方剂的轻重。先出现心烦而后心悸的，属于实证；先出现心悸而后心烦的，属于虚证。虚烦表现为心中郁闷想要呕吐的状态。
太阳病，出现心烦、自汗、小便频数的，不可使用桂枝汤，适宜使用芍药甘草汤。服用桂枝汤后，出汗后出现心烦口渴的，脉象洪大，使用白虎加人参汤。
阳明病，出现心烦、喜欢呕吐、壮热往来、心下部悸动、小便不利的，使用小柴胡汤加茯苓。伤寒发病两三天，心中悸动且心烦的，使用小建中汤。
发汗后病解，半天左右又出现心烦，脉象浮数的，可以再次发汗，使用桂枝汤。
鼻出血且心烦口渴的，喝水则呕吐水液，使用五苓散；若未痊愈，使用竹叶石膏汤。
泻下后白天烦躁夜间安静，口不渴、不呕吐，没有表证，脉象微沉的，使用干姜附子汤。若出现心中懊恼不适，使用栀子豉汤。
如果经过发汗或泻下治疗后，病仍未解除且出现烦躁的，使用茯苓四逆汤。严重泻下后六七天不大便，病未解除，腹部胀满疼痛的，有燥屎内结，使用大承气汤。吐、汗、下之后出现虚烦，心下部痞塞胀满，气向上冲至胸部，头晕目眩，身体震颤摇动，使用茯苓桂枝白术甘草汤。
肾伤寒，表里都没有热象，只是心烦意乱昏闷，不喜欢见到光亮，有时腹痛，脉象沉细，使用四逆汤。
烦是扰乱的意思，躁是愤怒（焦躁）的意思，躁是由先前的烦逐渐发展到躁动不安。伤寒出现的烦躁，有阴阳虚实的区别。心热则烦，属于阳实阴虚；肾热则躁，属于阴实阳虚。烦是热的轻症，躁是热的重症。有邪气在里而烦躁的，有不烦但直接出现躁闷的，这属于阳盛格阴，患者想睡在泥水中，连水都喝不下去。
或者结胸证具备而烦躁的，呕吐腹泻四肢厥冷而烦躁的，下利发热、四肢厥冷、烦躁不能入睡的，恶寒肌肉拘挛、脉象摸不到而躁动的，都属于不可治疗的危证。
太阳中风，脉象浮紧，发热且恶寒，身体疼痛，无汗且烦躁的，使用大青龙汤。患病二三天，脉象弱，没有太阳病的证候，使用柴胡汤。
证见烦躁，心下部坚硬，能进食的，用小承气汤轻微调和。心中悸动且烦躁的，使用小建中汤。
恶风、自汗，脉象濡弱且烦躁的，都采用这种方法（指上述对应方剂）。
仅发热六七天，口渴想喝水的，使用五苓散。没有发热，只是胡言乱语、烦躁的，使用五苓散，用水调服并探吐。
四肢厥冷，脉象沉、自下利、烦躁不能入睡的，使用黄连鸡子汤、黄连阿胶汤。
泻下后又发汗，白天烦躁不能入睡，夜间安静，不呕吐不口渴，没有表证，脉象沉微，身体没有大热，使用干姜附子汤。发汗或泻下后，病仍在不去，出现烦躁的，使用茯苓四逆汤。
阴极导致发躁，或者是阴毒火邪，投用热药反而病情加重的，不可用凉药，躁动严重时仍给予热性药剂，使用四逆汤之类的方剂。
烦是指扰乱心神，躁是指肢体躁动不安，躁往往是在烦的基础上逐渐发展而成的。伤寒中的烦躁，需辨别阴阳虚实。心热引起烦，多为阳实阴虚；肾热引起躁，多为阴实阳虚。烦是热邪较轻的表现，躁是热邪严重的表现。邪气在里导致的烦躁，以及不烦但直接出现躁闷的情况，属于阳盛格阴，患者甚至想卧于泥水中，饮水难以下咽。
若结胸证俱全而伴烦躁，或吐利伴四肢厥冷而烦躁，或下利发热、四肢厥冷、烦躁不得眠，或恶寒肢挛、脉绝不出而躁动，这些均为不治之证。
太阳中风，脉浮紧，发热恶寒，身痛，无汗而烦躁，用大青龙汤。得病二三日，脉弱，无太阳证，用柴胡汤。
证见烦躁，心下硬，能食者，用小承气汤微和之。心中悸而烦躁者，用小建中汤。
仅发热六七日，渴欲饮水者，用五苓散。无热，但狂言烦躁者，用五苓散，水调服并探吐。
下后复发汗，昼则烦躁不得眠，夜而安静，不呕不渴，无表证，脉沉微，身无大热，用干姜附子汤。发汗或下之，病仍在不去，烦躁者，用茯苓四逆汤。
When pathogenic heat transmits inward, if it has not undergone sweating, vomiting, or purging treatments, "fanre" (restless heat) will occur. This appears similar to fever but is essentially different. The Classics state: "When patients suffer from fanre, relief comes with sweating." If diaphragmatic heat has not yet formed, one should only employ mild harmonizing methods to resolve the slight heat. However, if there is fullness and vexation in the epigastrium, the treatments differ between inducing vomiting and purging; one must distinguish the deficiency or excess of the syndrome to determine the severity of the prescription. Vexation preceding palpitations indicates an Excess pattern; palpitations preceding vexation indicate a Deficiency pattern. Empty vexation manifests as a sensation of depression and nausea in the heart region.
In Taiyang disease, if there is heart vexation, spontaneous sweating, and frequent urination, Guizhi Tang (Cinnamon Twig Decoction) is contraindicated; Shaoyao Gancao Tang (Peony and Licorice Decoction) is appropriate. After taking Guizhi Tang, if vexation and thirst appear following sweating, and the pulse is flooding, Baihu Jia Renshen Tang (White Tiger Plus Ginseng Decoction) should be used.
In Yangming disease, if there is heart vexation, frequent vomiting, alternating high fever and chills, palpitations in the epigastrium, and difficult urination, Xiaochaihu Tang (Minor Bupleurum Decoction) with Fuling (Poria) is indicated. In Cold Damage, if within two to three days the patient experiences palpitations and vexation, Xiao Jianzhong Tang (Minor Construct the Middle Decoction) is prescribed.
After sweating resolves the condition, if vexation recurs after half a day and the pulse is floating and rapid, another sweating treatment may be applied using Guizhi Tang.
If there is nasal bleeding accompanied by vexation and thirst, and drinking water causes vomiting of fluids, Wuling San (Five-Ingredient Powder with Poria) is used; if this fails, Zhuye Shigao Tang (Bamboo Leaf and Gypsum Decoction) is employed.
If after purging, the patient is restless during the day but quiet at night, without thirst or vomiting, and lacking exterior signs, with a faint and deep pulse, Ganjiang Fuzi Tang (Dried Ginger and Aconite Decoction) is indicated. If there is inner restlessness and discomfort (Ao'nao), Zhizi Chidui Tang (Gardenia and Fermented Soybean Decoction) is used.
If after sweating or purging the disease remains unresolved and is accompanied by vexation and restlessness, Fuling Sini Tang (Poria and Sini Decoction) is used. After severe purging, if for six or seven days there is no bowel movement, the disease is unresolved, and there is abdominal fullness and pain due to dry feces, Dachengqi Tang (Major Order the Qi Decoction) is indicated. Following vomiting, sweating, or purging, if empty vexation occurs with epigastric stuffiness and fullness, qi rushing up to the chest, dizziness, and body tremors, Fuling Guizhi Baizhu Gancao Tang (Poria, Cinnamon Twig, Atractylodes, and Licorice Decoction) is prescribed.
In Kidney Cold Damage, with no heat in the interior or exterior, but only mental confusion and vexation, aversion to light, occasional abdominal pain, and a deep, fine pulse, Sini Tang (Recover the Yielding Decoction) is used.
"Fan" (vexation) refers to mental disturbance, while "Zao" (restlessness) refers to physical agitation arising from anger or distress; Zao develops gradually from Fan. In Cold Damage, Fan-Zao can be distinguished by Yin/Yang and Deficiency/Excess. Heart heat causes Fan, associated with Yang Excess and Yin Deficiency; Kidney heat causes Zao, associated with Yin Excess and Yang Deficiency. Fan represents mild heat, while Zao represents severe heat. When pathogenic factors are in the interior causing Fan-Zao, or when Zao occurs directly without prior Fan, this is termed Yang Excess repelling Yin. The patient may wish to lie in mud, and even water cannot be swallowed.
If the Jie Xiong (Chest Binding) syndrome is complete and accompanied by Fan-Zao, or if vomiting and diarrhea with cold limbs are accompanied by Fan-Zao, or if diarrhea with fever, cold limbs, and inability to sleep due to restlessness occur, or if there is aversion to cold, muscle cramping, absent pulse, and restlessness, these are all untreatable conditions.
In Taiyang Wind Strike, if the pulse is floating and tight, with fever, aversion to cold, body pain, absence of sweat, and restlessness, Da Qinglong Tang (Major Green Dragon Decoction) is used. If two to three days have passed since onset, the pulse is weak, and there are no Taiyang signs, Chaihu Tang (Bupleurum Decoction) is used.
If the syndrome presents with Fan-Zao, hardness in the epigastrium, and ability to eat, Xiao Chengqi Tang (Minor Order the Qi Decoction) is used to gently harmonize. If there are palpitations with Fan-Zao, Xiao Jianzhong Tang is used.
For those with aversion to wind, spontaneous sweating, a soft and weak pulse, and restlessness, the aforementioned methods apply.
If there is only fever for six or seven days and a desire to drink water, Wuling San is used. If there is no fever but only delirium and restlessness, Wuling San is administered with water, followed by induced vomiting.
In Yangming disease, if there is constipation, periumbilical pain, and restlessness, Chengqi Tang is used to purge.
In Shaoyang disease, if there is vomiting, diarrhea, cold limbs, and extreme restlessness, Wuzhuyu Tang (Evodia Decoction) is used.
With cold limbs, deep pulse, spontaneous diarrhea, and restlessness preventing sleep, Huanglian Jizi Tang (Coptis and Egg Yolk Decoction) or Huanglian Ejiao Tang (Coptis and Donkey-Hide Gelatin Decoction) are used.
After purging and subsequent sweating, if the patient is restless and unable to sleep during the day but quiet at night, without vomiting or thirst, lacking exterior signs, with a deep and faint pulse, and no significant fever, Ganjiang Fuzi Tang is used. If after sweating or purging the disease persists and is accompanied by restlessness, Fuling Sini Tang is used.
When Yin reaches its extreme, it may cause restlessness. Or, in cases of Yin toxicity or Fire Evil, if administering hot medicines worsens the condition, cooling medicines must not be used. If restlessness is severe, hot formulations such as Sini Tang should still be administered.
