仲景曰。脉微而涩者。此为医所病也。大发其汗。又数大下之。
其人亡血。病当恶寒。后乃发热无休止时。夏月盛暑。欲着复衣。冬
月盛寒。欲裸其身。所以然者。阳微则恶寒。阴弱则发热。此医发其
汗。使阳气微。又大下之。令阴气弱。五月之时。阴气在里。胃中虚
冷。以阳气内微。不能胜冷。故欲着复衣。十一月之时。阳气在内。胃
中烦热。以阴气内弱。不能胜热。故欲裸其身。又阴脉迟涩。故知亡
血也。庞氏曰。阳微。宜四逆汤。阴弱。宜苦酒艾之类。常氏云。宜小
建中汤。雍日。阳微阴弱之症。其候至微。亦未易言。仲景初谓亡血
之人。病当先寒。后乃发热。则一病之内。阳微阴弱之症。先后俱见
也。故言医发汗。使阳气微。又大下之。使阴气弱。则知一病是二证
也。夏月盛热。欲着复衣。冬月盛寒。欲裸其身。谓暑月犹有寒。不必
重言其热。寒月犹有热。不必重言其寒也。若如是。则暑月有寒热。
寒月亦有寒热。非五月病者独见寒。十月病者独见热也。故常氏用
小建中汤。似得其意。令阴阳两建之。虽药证相得。第恐力微。此外
亦无药矣。庞氏分寒热为两证。则阳微用四逆。阴弱用酸苦。然疾证
初不分。用药又难分也。夫然。则当见寒时用四逆。又恐后乃发热
时。热大甚不可制。若庞氏药。用之于表热里寒。表寒里热之证则相
宜。盖表热里寒。表寒里热。是自两病。非阳微阴弱同病之证也。粗
工以表热里寒。表寒里热。便为阳微阴弱者。尤非是。此证虽甚希
有。而前人论说。尚多失仲景之意。则后人用药宜审矣。
又曰。寸口脉浮大。而医反下之。此为大逆。浮则无血。大则为
寒。寒气相搏。则为腹鸣。医乃不知。而反饮冷水。令汗大出。水得寒
气。冷必相搏。其人则KT 。常氏云。宜甘草豆蔻散。

便利。必自愈。
又曰。下之后。复发汗。必振寒。脉微细。所以然者。内外俱虚故
也。常氏云。可 参建中汤。
又曰。本发汗。而反下之。此为逆也。若先发汗。治不为逆。本先
下之。而反汗之。为逆。若先下之。治不为逆。雍曰。此谓病当先汗而
反先下之者。故为逆。若已汗而后下之。不为逆也。若病当先下而反
先汗之。故为逆。若已下而后汗之。不为逆也。
又曰。太阳病。先下之而不愈。因复发汗。以此表里俱虚。其人
因致冒。冒家当汗出自愈。所以然者。汗出表和故也。得里未和。然
后复下之。常氏云。可桂枝大柴胡汤。雍曰。大字误。当是两药。先用

腹微满。郁郁微烦。先此时自极吐下者。当调胃承气汤。若不尔者。
不可与。但欲呕。胸中痛。微溏者。此非柴胡证。以呕。故知极吐下
也。雍曰。庞氏云。属调胃承气汤。误也。本论原无属字。不可妄加。
此一论当分作二证。所以本论继之以承气方者。谓前证当用之方。
非后证所属也。自若不尔之下。非柴胡汤证。为后证本论门治法。宜
生姜橘皮汤、大半夏加橘皮汤。
又曰。太阳病。重发汗而复下之。不大便五六日。舌上燥而渴。

张仲景说：脉象微细而涩的，这是医生治疗失误造成的。因为医生大发其汗，又多次峻下攻里。
导致患者失血，病症应当表现为恶寒，随后出现发热且无休止的时候。在夏季酷暑时，想要穿厚衣；在冬季严寒时，想要裸露身体。之所以这样，是因为阳气微弱则恶寒，阴气虚弱则发热。这是医生发汗，使阳气微弱，又大下攻里，令阴气虚弱。五月之时，阴气在体内，胃中虚冷，因为阳气内里微弱，不能抵御寒冷，所以想要穿厚衣。十一月之时，阳气在内，胃中烦热，因为阴气内里虚弱，不能抵御热邪，所以想要裸露身体。另外，阴脉迟涩，所以知道是失血。庞氏说：阳气微弱，适宜用四逆汤。阴气虚弱，适宜用苦酒艾叶之类的药物。常氏说：适宜用小建中汤。郭雍说：阳气微弱、阴气虚弱的病症，其征候非常细微，也不容易言明。张仲景起初说失血之人，病症应当先感到寒冷，随后才发热，那么在一个病证之内，阳气微弱和阴气虚弱的症状，先后都会出现。所以说医生发汗，使阳气微弱，又大下攻里，使阴气虚弱，就知道一个病证包含两种证候。夏季盛热，想要穿厚衣；冬季盛寒，想要裸露身体，是说暑月仍有寒意，不必重复说它热；寒月仍有热意，不必重复说它寒。如果像那样，那么暑月有寒热，寒月也有寒热，并非五月患病者独见寒，十月患病者独见热。所以常氏用小建中汤，似乎得其意旨，令阴阳两方皆得建立。虽然药证相符，但恐怕药力微弱，此外也没有其他药物了。庞氏将寒热分为两个证候，那么阳气微弱用四逆汤，阴气虚弱用酸苦之品。然而疾病证候起初并未分开，用药也难以区分。既然这样，那么在见到寒症时用四逆汤，又恐怕随后发热时，热势大甚无法控制。如果用庞氏的药物，用于表热里寒、表寒里热的证候则适宜。因为表热里寒、表寒里热，是两种不同的病证，并非阳气微弱和阴气虚弱同病的证候。粗劣的医生把表热里寒、表寒里热当作阳气微弱阴气虚弱，尤其不对。此证虽然极为罕见，而前人的论述，大多偏离张仲景的本意，那么后人用药应当审慎。
又说：寸口脉浮大，而医生反而用下法，这是大逆。浮脉表示无血，大脉表示有寒。寒气相互搏结，就会腹中鸣响。医生却不知道，反而让患者喝冷水，令大汗出。水遇到寒气，冷气必然相互搏结，患者就会发出“㖹”（形容干呕或呃逆的声音）声。常氏说：适宜用甘草豆蔻散。
又说：太阳病三天，已经发过汗，或者用过吐法、下法、温针，仍然不解的，这叫坏病。此时桂枝汤不再适用。应当观察其脉象和证候，知道犯了什么错误，随证进行治疗。
又说：脉象浮数的，按照法则应当出汗而痊愈。如果用了下法，出现身体沉重、心悸的，不可发汗，应当自然出汗而解。之所以这样，是因为尺中脉微，这是里虚。需要表里充实，津液自然调和，就会自然出汗而愈。常氏说：怀疑原文有缺漏。郭雍说：适宜用柴胡桂枝汤。
又说：凡是病证，如果发过汗，或者用过吐法、下法，或者失血，或者津液亡失，只要阴阳能够自我调和，必定自愈。
又说：峻下之后，再次发汗，小便不利的，是亡失津液的原因。不要强行治疗，等到小便通利，必定自愈。
又说：下法之后，再次发汗，必定出现振栗畏寒，脉象微细。之所以这样，是因为内外都虚的缘故。常氏说：可用参建中汤。
又说：本应发汗，却反而用下法，这叫逆治。如果先发汗，治疗就不算逆治。本应先下法，却反而发汗，这叫逆治。如果先下法，治疗就不算逆治。郭雍说：这是指病证应当先汗却反而先下的情况，所以叫逆治。如果已经发汗而后用下法，不算逆治。如果病证应当先下却反而先汗，所以叫逆治。如果已经下法而后发汗，不算逆治。
又说：太阳病，先用下法而不愈，因此再次发汗，以此导致表里俱虚。患者因此出现头目昏蒙（冒）。头目昏蒙的患者应当通过出汗而自愈。之所以这样，是因为汗出后表气调和的缘故。如果得到里气未和，然后再次用下法。常氏说：可用桂枝大柴胡汤。郭雍说：“大”字是误字，应当是两种药。先用柴胡桂枝汤调和其表，再次用下法时，用大柴胡汤。
又说：得病六七天，脉象迟浮弱，恶风寒，手足温暖，医生反复用下法，导致不能进食，胁下满痛，面目及全身发黄，颈项强直，小便困难的，给予小柴胡汤。随后必定出现肛门重坠感。本口渴饮水却呕吐的，小柴胡汤不适用。进食则呃逆的，常氏说：可用柴胡桂枝汤、干姜汤。饮水呕吐的，用五苓散。呃逆的，用小半夏汤。
又说：太阳病二三日，不能卧，只想起来，心下必定痞结。脉象微弱的，这是原本就有寒饮停聚。反而用下法，如果腹泻停止，必定形成结胸。如果腹泻未止，四五日再次用下法，这形成协热利。常氏说：可理中汤。结胸的，用大陷胸汤。协热利，表证未解的，用桂枝人参汤。
又说：太阳病，用下法后，脉象促（一说缓），没有形成结胸的，这是病欲解除。脉浮的，必定形成结胸。脉紧的，必定咽痛。脉弦的，必定两胁拘急。脉细数的，头痛未止。脉沉紧的，必定想呕吐。脉沉滑的，必定协热利。脉浮滑的，必定便血。常氏说：结胸，用陷胸汤。咽痛，用猪肤汤。两胁拘急，用小建中汤。头痛未止，用小柴胡汤。呕吐的，用小半夏汤。协热利的，用白头翁汤。便血的，用柏皮汤。郭雍说：柏皮汤即栀子柏皮汤。
又说：太阳少阳并病，反而用下法，形成结胸，心下硬，下利不止，水浆不下，其人心中烦乱。常氏说：可用陷胸汤。郭雍说：太少二阳，水木之气无相克害，因下法损伤胃气，三阳俱病。轻者不成结胸，适宜理中汤。或者无效的，适宜枳实理中丸。
又说：脉浮而紧，却又用下法，紧脉反入里，则形成痞证。按之柔软，只是气痞而已。常氏说：宜小陷胸汤、增损理中丸。郭雍说：先用枳实理中汤，不解，用半夏泻心汤。
又说：伤寒，吐下发汗后，虚烦，脉象极微，八九日后，心下痞硬，胁下痛，气上冲咽喉，眩晕昏冒，经脉跳动惕惧的，久则成痿证。常氏说：可用茯苓桂枝五味甘草汤。成痿证的，用振痿汤。（甘草汤未见方剂，怀疑用茯苓桂枝白术甘草汤。）
又说：阳明病，不能进食，如果攻其热，必定呃逆。之所以这样，是因为胃中虚冷的缘故。因为患者本身体虚，攻其热必定呃逆。常氏说：可用温中汤、小半夏汤。郭雍说：适宜理中汤。
又说：阳明病，脉迟，饮食难以吃饱，饱则轻微心烦、头眩，必定小便困难，这是将要发生谷疸。即使用了下法，腹满如故。之所以这样，是因为脉迟的缘故。常氏说：可用茵陈汤、五苓散。郭雍说：这应当煎煮茵陈汤一物来调服五苓散，制成茵陈蒿汤。
又说：病属阳多者热，用下法则大便硬。汗多极，再发汗也大便硬。常氏说：可小柴胡汤。
又说：太阳病，寸脉缓，关脉浮，尺脉弱。其人发热汗出，又恶寒，不呕，只是心下痞的，这是因为医生用下法造成的。常氏说：可生姜半夏二泻心汤。
又说：太阴病的证候，腹满而吐，食不下，自利益甚，时常腹部自痛。如果用下法，必定胸下结硬。常氏说：可桂枝加芍药汤、桂枝加大黄汤。郭雍说：本是太阳病，反而用下法，因腹满痛，转属太阴的，桂枝加芍药汤主治。大实痛的，用桂枝加大黄汤。现在证候见呕吐而食不下，自利，腹满自痛，都没有实证，不可直接用桂枝加大黄汤。有微寒的，应当适宜桂枝加附子汤。保留芍药而不去掉。
又说：伤寒，大吐大下之后，极度虚弱，又极度出汗的，其人外气怫郁，又给他喝水以发汗，因此得呃逆。之所以这样，是因为胃中寒冷的缘故。常氏说：可小温中汤。郭雍说：胃寒甚重的，理中汤。呃逆的，用小半夏汤、五苓散。
又说：吐利，发汗后，脉平，轻微烦闷的，因为新虚不胜谷气所致。常氏说：可调胃承气汤。郭雍说：不要服药，减少饮食则愈。因为脉平，不可再损伤。
又说：太阳病，医生发汗，于是发热恶寒，因此又用下法，心下痞，表里俱虚，阴阳之气并竭，无阳则阴独。再加烧针，因此胸烦，面色青黄，皮肤䐜胀（泽）的，难治。现在面色微黄，手足温暖的，易愈。常氏说：可小柴胡汤、桂枝龙骨牡蛎汤。郭雍说：心下痞的，枳实理中丸。烧针胸烦，桂枝加龙骨牡蛎汤。外证未除的，桂枝加人参汤。
又说：太阳病，得病八九天，像疟疾的样子，发热恶寒，热多寒少，人不呕，大小便尚正常，一天发作两三次，脉微（一作浮）缓的，为欲愈。脉微而恶寒的，这是阴阳俱虚，不可再发汗、再下、再吐。面色反有热色的，未欲解，因为他不能得小汗出，身体必定痒，属桂枝麻黄各半汤。
又说：服用桂枝汤，或者用下法，仍然头项强痛，翕翕发热，无汗，心下满，微痛，小便不利的，属桂枝去桂加茯苓白术汤。
又说：太阳病，先发汗不解，而下之，脉浮的，为不愈。浮脉表示病在外，而反用下法，所以令病不愈。现在脉浮，所以知道病在外，应当须解表则愈，宜桂枝汤。郭雍说：此证本当先汗，所谓如果先发汗，治疗就不算逆治。
又说：下之后，复发汗，昼日烦躁不得眠，夜间安静，不呕不渴，无表证，脉沉迟，身无大热的，属干姜附子汤。郭雍说：此证本当先下，所谓如果先下之，治疗就不算逆治。
又说：伤寒，如果吐如果下后，心下逆满，气上冲胸，起则头眩，脉沉紧，发汗则动经，身体振振动摇的，属茯苓桂枝白术甘草汤。
又说：发汗吐下后，虚烦不得眠，如果严重的，必定反复颠倒，心中懊憹，属栀子豉汤。如果少气的，栀子甘草豉汤。如果呕吐的，栀子生姜豉汤。

Zhang Zhongjing said: A pulse that is faint (Wei, 微) and choppy (Se, 涩) indicates iatrogenic injury. This results from excessive sweating followed by repeated severe purgation.
The patient has lost blood. The condition should initially present with aversion to cold, followed by fever without cessation. In the height of summer heat, the patient desires to wear thick clothing; in the depth of winter cold, the patient desires to be naked. The reason for this is that faint Yang leads to aversion to cold, while weak Yin leads to fever. This occurs because the physician's excessive sweating caused Yang Qi (Vital Energy) to become faint, and severe purgation caused Yin Essence (Substance) to become weak. In the fifth month, Yin Qi resides within, leaving the stomach empty and cold. Because internal Yang is faint and cannot overcome the cold, the patient desires thick clothing. In the eleventh month, Yang Qi resides within, causing vexatious heat in the stomach. Because internal Yin is weak and cannot overcome the heat, the patient desires to be naked. Furthermore, a slow and choppy Yin pulse indicates blood loss.
Pang Shi said: For faint Yang, Sini Tang (Frigid Four Decoction) is appropriate. For weak Yin, substances such as vinegar and mugwort are appropriate. Chang Shi said: Xiaojianzhong Tang (Minor Construct the Middle Decoction) is appropriate.
Guo Yong said: The symptoms of faint Yang and weak Yin are extremely subtle and difficult to articulate. Zhang Zhongjing initially stated that patients who have lost blood should first feel cold, then develop fever. Thus, within a single disease process, both faint Yang and weak Yin symptoms appear sequentially. Therefore, when he says the physician's sweating made Yang faint and purgation made Yin weak, it implies that one disease encompasses two syndromes. "In summer heat, desiring thick clothing; in winter cold, desiring nudity" means that even in hot months there is underlying coldness, so there is no need to reiterate heat; and in cold months there is underlying heat, so there is no need to reiterate cold. If interpreted otherwise, it would imply that both summer and winter present with alternating cold and heat, rather than May patients presenting uniquely with cold and October patients with heat. Thus, Chang Shi's use of Xiaojianzhong Tang seems to grasp the intent, establishing both Yin and Yang. Although the herbs match the syndrome, the efficacy may be weak, and few other formulas exist for this. Pang Shi divided cold and heat into two separate syndromes, using Sini Tang for faint Yang and sour/bitter agents for weak Yin. However, since the initial disease presentation does not clearly distinguish them, differentiating treatment is difficult. If one uses Sini Tang when cold signs appear, one risks uncontrolled heat when fever arises later. Pang Shi's approach is suitable for exterior-heat/interior-cold or exterior-cold/interior-heat syndromes. These represent distinct pathologies, not the simultaneous occurrence of faint Yang and weak Yin. Unskilled physicians mistake exterior-heat/interior-cold or exterior-cold/interior-heat for faint Yang/weak Yin, which is incorrect. Although this syndrome is rare, many previous commentaries deviate from Zhang Zhongjing's original meaning; thus, subsequent practitioners must exercise caution.
It is also said: If the Cun (inch) position pulse is floating (Fu, 浮) and large (Da, 大), but the physician erroneously applies purgation, this is a major contraindication. Floating indicates blood deficiency; large indicates cold. When cold qi clashes, abdominal borborygmus occurs. The physician, unaware, forces the patient to drink cold water to induce profuse sweating. The water clashes with the cold qi, causing the patient to make a dry heaving sound (Kun). Chang Shi said: Gancao Doukou San (Licorice and Cardamom Powder) is appropriate.
It is also said: In Taiyang disease (Taiyang Disease, 太阳病), after three days, if sweating, vomiting, purgation, or warm needle therapy have been applied yet the condition remains unresolved, this is termed a "ruined disease" (Huai Bing, 坏病). Guizhi Tang (Cinnamon Twig Decoction) is no longer applicable. One must observe the pulse and symptoms, identify the iatrogenic error, and treat according to the current syndrome.
It is also said: A floating and rapid (Shuo, 数) pulse indicates that sweating should lead to recovery. If purgation is used instead, resulting in heavy body sensation and palpitations, sweating is contraindicated. Recovery will occur through spontaneous sweating. This is because the Chi (cubit) position pulse is faint, indicating interior deficiency. The interior and exterior must be fortified, and fluids must harmonize spontaneously for recovery via sweating. Chang Shi suspected textual omission. Guo Yong suggested Chaihu Guizhi Tang (Bupleurum and Cinnamon Twig Decoction).
It is also said: In any disease, whether following sweating, vomiting, purgation, blood loss, or fluid depletion, if Yin and Yang achieve self-harmony, spontaneous recovery will occur.
It is also said: After severe purgation followed by sweating, urinary difficulty arises due to fluid depletion. Do not forcibly treat it; once urination normalizes, the condition will resolve spontaneously.
It is also said: Following purgation and then sweating, chills and fine, faint pulses occur because both interior and exterior are deficient. Chang Shi suggested Shen Jianzhong Tang (Ginseng and Minor Construct the Middle Decoction).
It is also said: If sweating was indicated but purgation was used erroneously, this is a counter-indication. If sweating is performed first, it is not an error. If purgation was indicated but sweating was used erroneously, this is a counter-indication. If purgation is performed first, it is not an error. Guo Yong clarified: This refers to treating a syndrome requiring sweating with purgation first, which is erroneous. Sweating followed by purgation is acceptable. Conversely, treating a syndrome requiring purgation with sweating first is erroneous; purgation followed by sweating is acceptable.
It is also said: In Taiyang disease, if purgation fails and sweating is subsequently applied, leading to exterior-interior deficiency, the patient may experience "Mao" (vertigo/dizziness). Spontaneous sweating will resolve this vertigo because it harmonizes the exterior. If the interior remains discordant, purgation may be applied subsequently. Chang Shi suggested Guizhi Daxiehu Tang (Cinnamon Twig and Major Bupleurum Decoction). Guo Yong noted "Da" is likely an error, implying two formulas: first Chaihu Guizhi Tang to harmonize the exterior, then Daxiehu Tang for purgation.
It is also said: On the sixth or seventh day of illness, with a slow, floating, weak pulse, aversion to wind and cold, warm hands and feet, repeated purgation by the physician leads to inability to eat, fullness/pain in the hypochondrium, jaundice of the face/body, stiff neck, and difficult urination. Give Chaihu Tang (Bupleurum Decoction). Subsequently, rectal heaviness may occur. If thirst with drinking leads to vomiting, Chaihu Tang is contraindicated. If eating triggers hiccups, Chang Shi suggested Chaihu Guizhi Tang or Ganjiang Tang (Ginger Decoction); for thirst/vomiting, Wuling San (Five Ingredient Powder); for hiccups, Xiaobanxia Tang (Minor Pinellia Decoction).
It is also said: In Taiyang disease on days two or three, inability to lie down, desire to rise, and epigastric binding indicate pre-existing cold-fluid retention. Erroneous purgation may lead to Jie Xiong (Chest Binding) if diarrhea stops, or Xie Re Li (Collaborating Heat Diarrhea) if diarrhea persists and purgation is repeated after four to five days. Chang Shi suggested Lizhong Tang (Regulate the Middle Decoction) for diarrhea; Daxiexiong Tang (Major Chest-Breaking Decoction) for Jie Xiong; Guizhi Renshen Tang (Cinnamon Twig and Ginseng Decoction) for Xie Re Li with unresolved exterior.
It is also said: After purgation in Taiyang disease, a Cu (surging) pulse (or Huan, slow) without Jie Xiong indicates impending resolution. A floating pulse indicates Jie Xiong; tight pulse indicates sore throat; wiry pulse indicates bilateral hypochondriac stiffness; fine-rapid pulse indicates persistent headache; deep-tight pulse indicates nausea; deep-slippery pulse indicates Xie Re Li; floating-slippery pulse indicates bloody stool. Chang Shi suggested Xiexiong Tang for Jie Xiong; Zhufu Tang (Pig Skin Decoction) for sore throat; Xiaojianzhong Tang for hypochondriac stiffness; Xiaochaihu Tang for headache; Xiaobanxia Tang for nausea; Baitouweng Tang (Podophyllium Decoction) for Xie Re Li; Bapi Tang (Phellodendron Bark Decoction) for bloody stool. Guo Yong identified Bapi Tang as Zhi Zi Bai Pi Tang (Gardenia and Phellodendron Bark Decoction).
It is also said: In concurrent Taiyang-Shaoyang disease, erroneous purgation causes Jie Xiong, epigastric hardness, incessant diarrhea, inability to swallow liquids, and irritability. Chang Shi suggested Xiexiong Tang. Guo Yong explained that Shaoyang-Water and Taiyang-Wood do not clash; purgation damages the Stomach, affecting all three Yang channels. Mild cases do not form Jie Xiong; Lizhong Tang is appropriate. If ineffective, Zhishi Lizhong Wan (Immature Bitter Orange and Regulate the Middle Pill) is suitable.
It is also said: A floating-tight pulse treated with purgation causes the tightness to enter the interior, forming Pi (Glomus/Blockage). Palpation reveals softness, indicating only Qi Blockage. Chang Shi suggested Xiao Xiexiong Tang (Minor Chest-Breaking Decoction) and Zengsun Lizhong Wan. Guo Yong suggested Zhishi Lizhong Tang first; if unresolved, Banxia Xiexin Tang (Pinellia and Heart-Draining Decoction).
It is also said: After vomiting, purgation, or sweating in Shanghan (Cold Damage), lingering vexation with a very faint pulse, progressing over eight to nine days to epigastric hardness, hypochondriac pain, Qi rushing to the throat, vertigo, and muscle twitching, may eventually lead to Wei (Atrophy) syndrome. Chang Shi suggested Fuling Guizhi Wuwei Gancao Tang (Poria, Cinnamon Twig, Schisandra, and Licorice Decoction). For established Wei syndrome, Zhenwei Tang (Shake Atrophy Decoction) is cited (note: Gancao Tang formula missing, possibly Fuling Guizhi Baizhu Gancao Tang).
It is also said: In Yangming disease, inability to eat combined with clearing heat leads to hiccups due to Stomach deficiency-cold. Given the patient's inherent deficiency, attacking heat induces hiccups. Chang Shi suggested Wenzhong Tang (Warm the Middle Decoction) and Xiaobanxia Tang. Guo Yong suggested Lizhong Tang.
It is also said: In Yangming disease, a slow pulse with difficulty tolerating full meals (leading to mild vexation, dizziness, and difficult urination) suggests impending Gu Dan (Grass Jaundice). Purgation will not relieve abdominal fullness due to the slow pulse. Chang Shi suggested Yichen Tang (Artemisia Capillaris Decoction) and Wuling San. Guo Yong suggested combining Yichen Tang with Wuling San to create Yinchen Hao Tang (Artemisia, Mugwort, and Rhubarb Decoction).
It is also said: Diseases with excess Yang present with heat; purgation causes hardness. Excessive sweating also causes hardness. Chang Shi suggested Xiaochaihu Tang.
It is also said: In Taiyang disease, a slow Cun pulse, floating Guan pulse, and weak Chi pulse, accompanied by fever, sweating, aversion to cold, no vomiting, but epigastric blockage, results from erroneous purgation. Chang Shi suggested Shengjiang Banxia Er Xiexin Tang (Fresh Ginger, Pinellia, and Two Heart-Draining Decoctions).
It is also said: Taiyin disease presents with abdominal fullness, vomiting, inability to eat, worsening spontaneous diarrhea, and intermittent abdominal pain. Purgation causes lower chest binding. Chang Shi suggested Guizhi Ji Shaoyao Tang (Cinnamon Twig Added Peony Decoction) or Guizhi Ji Dahuang Tang (Cinnamon Twig Added Rhubarb Decoction). Guo Yong clarified: If Taiyang disease turns to Taiyin with abdominal fullness/pain, Guizhi Ji Shaoyao Tang is primary. For severe painful fullness, Guizhi Ji Dahuang Tang. However, with vomiting, food intolerance, diarrhea, and non-severe pain, there is no excess syndrome; Guizhi Ji Dahuang Tang is contraindicated. For mild cold, Guizhi Ji Fuzi Tang (Cinnamon Twig Added Aconite Decoction) is appropriate, retaining Peony.
It is also said: After severe vomiting and purgation in Shanghan, extreme deficiency ensues. Further excessive sweating causes external Qi stagnation. Giving water to induce sweating triggers hiccups due to Stomach cold. Chang Shi suggested Xiaowenzhong Tang (Minor Warm the Middle Decoction). Guo Yong suggested Lizhong Tang for severe Stomach cold; Xiaobanxia Tang or Wuling San for hiccups.
It is also said: After vomiting, diarrhea, and sweating, if the pulse is level but mild vexation persists, it is due to new deficiency failing to transform grain Qi. Chang Shi suggested Tiaoweichengqi Tang (Regulate the Stomach and Drain the Ganglion Decoction). Guo Yong advised against medication; dietary restriction resolves it, as the pulse is level and further damage is harmful.
It is also said: In Taiyang disease, excessive sweating followed by purgation causes epigastric blockage, exterior-interior deficiency, and exhaustion of Yin-Yang Qi. "No Yang means Yin stands alone." Adding fire needle therapy causes chest irritability. Cyan-yellow complexion and flaccid skin indicate difficult treatment. Yellowish complexion and warm hands/feet indicate easy recovery. Chang Shi suggested Xiaochaihu Tang or Guizhi Longgu Muli Tang (Cinnamon Twig, Dragon Bone, and Oyster Shell Decoction). Guo Yong suggested Zhishi Lizhong Wan for epigastric blockage; Guizhi Longgu Muli Tang for fire needle chest irritability; Guizhi Ji Renshen Tang (Cinnamon Twig Added Ginseng Decoction) for unresolved exterior signs.
It is also said: In Taiyang disease lasting eight to nine days, resembling malaria with more heat than cold, no vomiting, normal bowel/bladder function, occurring two to three times daily, with a faint (or floating) slow pulse indicates recovery. A faint pulse with aversion to cold indicates dual Yin-Yang deficiency; sweating, purgation, and vomiting are contraindicated. A reddish facial color indicates unresolved disease due to inability to sweat slightly, causing body itching; this belongs to Guizhi Mahuang Gemi Tang (Cinnamon Twig and Ephedra Half-Dose Decoction).
It is also said: After Guizhi Tang or purgation, if head/neck stiffness, low-grade fever, anhidrosis, epigastric fullness, mild pain, and urinary difficulty persist, this belongs to Guizhi Qu Gui Jia Fuling Baizhu Tang (Cinnamon Twig Decoction Without Cinnamon Plus Poria and Atractylodes Macrocephala Decoction).
It is also said: In Taiyang disease, if initial sweating fails and purgation is used, a floating pulse indicates non-recovery. Floating indicates exterior pathology; purgation is inappropriate. Since the pulse is floating, the exterior must be resolved with Guizhi Tang. Guo Yong noted this aligns with the principle that sweating first is not an error.
It is also said: After purgation and sweating, daytime restlessness with nighttime quietness, no vomiting/thirst, no exterior signs, deep-slow pulse, and lack of high fever belong to Ganjiang Fuzi Tang (Ginger and Aconite Decoction). Guo Yong noted this aligns with the principle that purgation first is not an error.
It is also said: After vomiting/purgation in Shanghan, epigastric fullness/reversal, Qi rushing to the chest, vertigo upon rising, deep-tight pulse, and body tremors after sweating belong to Fuling Guizhi Baizhu Gancao Tang (Poria, Cinnamon Twig, Atractylodes Macrocephala, and Licorice Decoction).
It is also said: After sweating or purgation, if the disease persists with irritability, this belongs to Fuling Sini Tang (Poria and Frigid Four Decoction).
It is also said: After sweating/vomiting/purgation, lingering vexation and insomnia, potentially severe enough to cause restlessness and Ao Nao (regretful vexation), belong to Zhizi Chi Tang (Gardenia and Fermented Soybean Decoction). For shortness of breath, Zhizi Gancao Chi Tang; for vomiting, Zhizi Shengjiang Chi Tang.
It is also said: After sweating or purgation, if vexatious heat and chest oppression occur, this belongs to Zhizi Chi Tang syndrome.
It is also said: In Taiyang syndrome passing the stage for over ten days, with epigastric nausea, chest pain, loose stools, mild abdominal fullness, and mild vexation, resulting from prior extreme vomiting/purgation, Tiaoweichengqi Tang is indicated. Otherwise, it is contraindicated. If merely nauseous with chest pain and loose stools, it is not a Chaihu syndrome but a result of extreme vomiting/purgation. Guo Yong criticized Pang Shi's attribution to Tiaoweichengqi Tang, noting the original text lacks "belongs to." He argued this passage describes two syndromes: the first requires Chengqi formulas; the second (post-"if not so") requires Jiangsheng Jupi Tang (Fresh Ginger and Tangerine Peel Decoction) or Banxia Jupi Tang (Pinellia and Tangerine Peel Decoction).
It is also said: In Taiyang disease, after excessive sweating and purgation, if constipation persists for five to six days, with dry tongue, thirst, late-afternoon tidal fever, and hardness/pain from epigastrium to lower abdomen, this belongs to Daxiexiong Tang (Major Chest-Breaking Decoction).
It is also said: In Shanghan on day five or six, after sweating and purgation, if hypochondriac fullness, slight binding, urinary difficulty, thirst without vomiting, head-only sweating, alternating chills/fever, and irritability persist, the disease is unresolved. This belongs to Chaihu Guizhi Ganjiang Tang (Bupleurum, Cinnamon Twig, and Ginger Decoction).
It is also said: After resolving Shanghan via sweating/vomiting/purgation, if epigastric hardness and persistent belching remain, this belongs to Xuanfu Daizheshi Tang (Inula and Hematite Decoction).
It is also said: After severe purgation and sweating in Shanghan, if epigastric blockage and aversion to cold persist, the exterior is unresolved. Do not attack the blockage; resolve the exterior first with Guizhi Tang (Cinnamon Twig Decoction). Once the exterior is resolved, attack the blockage with Dahuang Huanglian Xiexin Tang (Rhubarb, Coptis, and Heart-Draining Decoction).
It is also said: After vomiting/purgation in Shanghan, if unresolved after seven to eight days, with interior heat, exterior-interior heat, frequent aversion to wind, intense thirst, dry tongue, and desire to drink several liters of water, Baihu Ji Renshen Tang (White Tiger Added Ginseng Decoction) is indicated.
It is also said: After vomiting/purgation in Shanghan, if unresolved with constipation for five to ten+ days, presenting with late-afternoon tidal fever, no aversion to cold, delirious speech as if seeing ghosts, severe cases showing confusion, grasping at clothes, fearfulness, slight panting, and fixed gaze: wiry pulse indicates survival, choppy pulse indicates death. Mild cases with fever and delirium belong to Dachengqi Tang (Major Drain the Ganglion Decoction).
It is also said: In combined Three-Yang disease, with heavy abdomen/body, difficulty turning, impaired mouth sensation, facial grease, delirium, and enuresis: sweating worsens delirium; purgation causes forehead sweating and cold limbs. Spontaneous sweating indicates Baihu Tang (White Tiger Decoction).
It is also said: In Yangming disease, with floating-tight pulse, dry throat, bitter taste, abdominal fullness, wheezing, fever, sweating, no aversion to cold but aversion to heat, and body heaviness: sweating causes irritability and delirium; warming needles cause fearfulness and insomnia; purgation empties the Stomach, allowing hostile Qi to disturb the Diaphragm, causing Ao Nao and tongue coating. This belongs to Zhizi Chi Tang. Pang Shi noted: Stop Zhizi Tang once effective; contraindicated in patients with chronic loose stools.
It is also said: In Yangming disease, after purgation, if Ao Nao and irritability occur with dry feces in the Stomach, purgation is permissible. If abdominal fullness is mild with hard head but loose tail, purgation is contraindicated. If dry feces are confirmed, Dachengqi Tang is appropriate.
It is also said: In Yangming disease, after purgation, if exterior heat and warm hands/feet persist without Jie Xiong, but Ao Nao, hunger without ability to eat, and head-only sweating occur, this belongs to Zhizi Chi Tang.
It is also said: In Taiyang disease, after vomiting/purgation/sweating, if mild vexation, frequent urination, and hard stools occur, give Xiaochengqi Tang (Minor Drain the Ganglion Decoction) to harmonize and cure.
It is also said: Profuse sweating or severe diarrhea leading to cold extremities belongs to Sini Tang (Frigid Four Decoction).
It is also said: In Taiyang disease, after purgation, if Qi rushes upward, Guizhi Tang may be given. If not, it is contraindicated. Guo Yong added: If Qi does not rush, consider Guizhi Qu Shaoyao Jia Fuzi Tang (Cinnamon Twig Decoction Without Peony Added Aconite), Guizhi Ji Houpo Zixi Tang (Cinnamon Twig Added Magnolia Bark and Apricot Kernel), or Gegen Huangqin Huanglian Tang (Kudzu, Scutellaria, and Coptis Decoction) based on subsequent syndromes.
It is also said: In Taiyang disease, after purgation, if pulse is Cu (surging) with chest fullness, this belongs to Guizhi Qu Shaoyao Tang (Cinnamon Twig Decoction Without Peony). If mild aversion to cold occurs, use Guizhi Qu Shaoyao Jia Fuzi Tang. (Note: Pulse Jing combines these two syndromes).
It is also said: In Taiyang disease with Guizhi syndrome, if purgation is erroneously used causing incessant diarrhea with a Cu pulse, the exterior remains unresolved. Wheezing with sweating belongs to Gegen Huangqin Huanglian Tang.
It is also said: In Taiyang disease, if purgation causes mild wheezing with unresolved exterior, this belongs to Guizhi Ji Houpo Zixi Tang.
It is also said: In Shanghan, if constipation persists for six to seven days with headache and fever, Chengqi Tang may be given. If urine is clear, the pathogen is in the exterior, not interior; sweating is required. If headache persists, nasal bleeding may occur; Guizhi Tang is appropriate. Chang Shi doubted this, suggesting Mahuang Tang (Ephedra Decoction) or Gemi Tang for heavy sweating. Guo Yong clarified: Use Guizhi Tang if sweating; Mahuang Tang if anhidrotic. See Nosebleed section.
It is also said: In Shanghan on day five or six, after severe purgation, if body heat persists and heart-region pain occurs, the disease is unresolved. This belongs to Zhizi Chi Tang.
It is also said: After purgation in Shanghan, if irritability, abdominal fullness, and restlessness occur, this belongs to Zhizi Houpo Tang (Gardenia and Magnolia Bark Decoction).
It is also said: In Shanghan, if harsh pill-based purgation leaves body heat and mild vexation, this belongs to Zhizi Ganjiang Tang (Gardenia and Ginger Decoction).
It is also said: In Shanghan, after purgation, if continuous diarrhea with undigested food and body pain occur, urgently rescue the interior with Sini Tang. Once bowels normalize and pain persists, urgently rescue the exterior with Guizhi Tang.
It is also said: In Taiyang disease passing the stage for ten+ days, if erroneous purgation is repeated and Chaihu syndrome persists after four to five days, first give Xiaochaihu Tang. If vomiting persists, epigastric urgency, and mild vexation remain, the disease is unresolved; give Daxiehu Tang to purge and cure. Guo Yong noted: If vomiting stops and peace returns after Xiaochaihu Tang, do not administer Daxiehu Tang.
It is also said: In Shanghan lasting thirteen days, unresolved with hypochondriac fullness, vomiting, and late-afternoon tidal fever, followed by mild diarrhea: this was originally a Chaihu syndrome. Purging should not cause diarrhea; the presence of diarrhea indicates the physician used inappropriate pill-based purgation. Tidal fever indicates excess. First give Xiaochaihu Tang to resolve the exterior, then Chaihu Jia Mangxiao Tang (Bupleurum Added Mirabilite Decoction).
It is also said: In Shanghan lasting thirteen days, passing the stage with delirium indicates heat; purgation with decoction is indicated. If urination is free, stool should be hard; paradoxical diarrhea with a harmonious pulse indicates inappropriate pill-based purgation by the physician.
