《伤寒论》有哕无呃。按《灵枢》治哕篇，以草刺鼻作嚏，嚏已无息，疾迎引之，立已。大惊
之，亦已。推之即今外治呃逆之法。方书以干呕与哕，妄拟咳逆。夫咳逆者，以咳嗽气逆立
名。呃者，胃气不和，上冲作声，听声命名，故曰呃逆。呃逆之症，若身发寒热，呕逆作
呃，此表邪传少阳也。若见左脉浮紧，身热无汗，羌活柴胡汤主之。若有汗，脉数，小柴胡
合清胆汤。若内热口渴，呃声作止，时时汗出，唇焦便结，右脉沉数，此阳明里热上冲也，
干葛竹茹汤，竹茹清胃汤。若里热便闭，六脉数大者，用泻心汤，凉膈散。有下症者，承气
汤。若胃热兼虚者，人参橘皮竹茹汤。若中脘多痰，右脉滑大者，二陈竹茹加枳桔。有痰有
火，脉沉而数者，栀连二陈汤加葛根、竹茹，或导痰汤下之。若食滞中焦，气口脉滑者，平
胃保和散。若误服寒凉，六脉沉迟，中焦凝滞者，宜大顺饮温中保和散。若阴火上冲而呃逆
者。知柏四物汤。另有初起不发热，口不渴，二便清利，六脉沉迟而见呃逆，此阴症寒呃
也，轻则理中汤，重则四逆汤，丁香柿蒂汤主治。
阳明中风，脉弦浮大而短气，腹都满，胁下及心痛，久按之气不通，鼻干，不得汗，嗜卧，
一身及面目悉黄，小便难，有潮热，时时哕。耳前后肿，刺之小瘥，外不解。病过十日，脉
续浮者，与小柴胡汤。脉但浮无余症者，与麻黄汤。若不尿，腹满加哕者，不治。
阳明病，脉弦，少阳也。脉浮大，太阳也，腹满胁下及心痛，少阳症也。鼻干不得汗，嗜
卧，面目悉黄，有潮热，时时哕者，阳明症也。耳前后肿，刺之小瘥，外不解，病过十
日，脉续浮，则用小柴胡汤，引阳明之邪，从少阳而出。脉但浮无余症者，则以麻黄汤。
引阳明之邪，从少阳而出，如法治之。若原不尿，腹满反加哕者，不治。
阳明病，不能食，攻其热必哕。所以然者，胃中虚冷故也。以其人本虚，故攻热必哕。
阳明不能食，有寒热二条∶胃热不能食，攻其热则愈∶胃寒不能食，攻其热必哕呃。下文
申明二条。
又云∶脉浮而迟者，表热里寒，下利清谷者，四逆汤主之。若胃中虚冷不能食者，水饮则哕。
言阳明里寒不能食，不但寒凉而哕，即饮水亦哕。
伤寒哕而腹满，视其前后，知何部不利，利之则愈。
言阳明胃实，哕而腹满，当视前后何窍不利，以利之。

丁香 柿蒂 人参 生姜
此治寒呃之方。今人以此治阳症呃逆，大谬。
《伤寒论》中只有“哕”而没有“呃”。根据《灵枢·杂病篇》治疗哕的方法，用草刺激鼻子引起打喷嚏，喷嚏打完气息停止，迅速牵引患者，症状立刻消失；或者突然惊吓患者，也能治愈。推究起来，这就是现在外治法治疗呃逆的原理。医书将干呕与哕，错误地拟名为咳逆。所谓咳逆，是因为咳嗽气逆而命名。呃，是胃气不和，向上冲逆发出声音，根据声音来命名，所以称为呃逆。
呃逆的症状，如果身体出现寒热交替，呕吐并伴随呃逆，这是表邪传入少阳经。如果见到左脉浮紧，身体发热且无汗，主治方剂为羌活柴胡汤。如果有汗，脉象数，用小柴胡汤合清胆汤。如果体内有热且口渴，呃声时作时止，经常出汗，嘴唇焦裂，大便干结，右脉沉数，这是阳明里热上冲所致，可用干葛竹茹汤或竹茹清胃汤。如果里有热且大便闭塞，六脉皆数大，使用泻心汤或凉膈散。如果有可攻下的证候，使用承气汤。如果是胃热兼有虚证，用人参橘皮竹茹汤。如果中脘部位痰多，右脉滑大，使用二陈竹茹汤加枳壳、桔梗。如果有痰又有火，脉象沉而数，使用栀连二陈汤加葛根、竹茹，或者用导痰汤送服。如果食物停滞在中焦，气口脉滑，使用平胃保和散。如果误服寒凉药物，导致六脉沉迟，中焦凝滞，适宜用大顺饮温中，配合保和散。如果是阴火上冲导致的呃逆，使用知柏四物汤。另外，起初不发热，口不渴，大小便清利，六脉沉迟而出现呃逆的，这是阴证寒呃，轻症用理中汤，重症用四逆汤，丁香柿蒂汤主治。
阳明中风，脉象弦、浮、大且短气，腹部全面胀满，胁下及心痛，长时间按压后气机不通畅，鼻干，无汗，嗜睡，全身及面目都发黄，小便困难，有潮热，经常打哕。耳前后肿胀，针刺后稍好转，但表证未解。病程超过十天，脉象持续浮的，给予小柴胡汤。脉象仅浮而无其他症状的，给予麻黄汤。如果不排尿，腹部胀满且加重打哕的，属于不治之症。
阳明病，脉弦，属于少阳经病变。脉浮大，属于太阳经病变。腹部胀满、胁下及心痛，是少阳证。鼻干、无汗、嗜睡、面目全黄、有潮热、经常打哕，是阳明证。耳前后肿胀，针刺后稍好转，表证未解，病程超过十天，脉象持续浮，则用小柴胡汤，引导阳明之邪从少阳经排出。脉象仅浮而无其他症状的，则用麻黄汤，引导阳明之邪从少阳经排出（注：此处原文逻辑似有误，通常麻黄汤解表，小柴胡和解，但依原文翻译），依法治疗。如果原本不排尿，腹部胀满反而加重打哕的，属于不治之症。
阳明病，不能进食，若用清热法攻伐，必然导致哕。之所以这样，是因为胃中虚冷。因为病人本身体虚，所以攻伐热邪必然导致哕。
阳明病不能进食，分为寒热两条：胃热导致不能进食，攻伐其热则痊愈；胃寒导致不能进食，攻伐其热必然导致哕呃。下文对此进行说明。
又说：脉象浮而迟缓的，是表热里寒，伴有下利清谷（完谷不化）的，用四逆汤主治。如果胃中虚冷不能进食，饮水也会导致哕。意思是阳明里寒不能进食，不仅仅是服用寒凉药会哕，就是喝水也会哕。
伤寒出现哕且腹部胀满，观察前阴和后阴，知道哪个部位不利，通利它就能痊愈。
意思是阳明胃实，哕且腹部胀满，应当观察前后二窍哪个不通利，通利它即可。
羌活柴胡汤
组成：羌活、柴胡、防风、黄芩、广皮（陈皮）、半夏、甘草。
主治寒热往来、呕吐、口苦、耳聋、胁痛且呃逆，应当治疗少阳经。见到恶寒头痛，即为少阳兼太阳经证，所以用此方兼治太阳经。
小柴胡汤 （见寒热章节）。
少阳太阳经呃逆，用前方发散表邪。如果没有太阳经表邪，直接用此方加竹茹、厚朴，即合清胆汤之意。
承气汤 （见大便结章节）。
泻心汤 （见痞满章节）。
中焦有痰火，被寒凉药物抑制遏阻，常常导致呃逆。此方以黄连、干姜同用，调理里气，佐以半夏，辛散痰涎。兼见呕吐的，加竹茹、藿香；气逆阻滞的，加枳壳、厚朴。
凉膈散 （见发狂章节）。
各种气逆上冲，都属于火。所以阳证呃逆，热而无积滞，就用此方清泄。如果见到可下之症，加玄明粉。
人参橘皮竹茹汤
组成：橘皮、竹茹、生姜、厚朴、半夏、甘草、人参、藿香。
呃逆伴有表证，先散表邪；呃逆有痰火，用栀连竹茹汤、栀连二陈汤；冷热不调，用半夏泻心汤。如今因表邪已解，里没有实热，只是胃虚导致的呃逆，所以用此方补益胃气，调和其中。
二陈竹茹汤
组成：熟半夏、白茯苓、广皮、甘草、竹茹、枳壳、桔梗。
胃热呃逆，用凉膈散；冷热不调，用泻心汤；胃虚呃逆，用人参橘皮汤。如今因痰凝气窒，所以用二陈汤加竹茹、枳壳、桔梗。栀连二陈汤，加干葛、竹茹。
呕吐呃逆，因胃家痰火，所以用栀连二陈汤，加竹茹清胆火，干葛宣发胃热，不仅能治呃逆，还能治呕吐。
平胃散 （见谵语章节）。
胃家湿郁食滞，也会引发呃逆。大致而言，右脉实大但不数，就是食积满闷导致的呃逆，不可妄用寒凉药。胃实者，此方加枳实、莱菔子、青皮；呕吐，加半夏、藿香。
保和散 （见胸满章节）。
湿郁食滞，用前方平胃散，必须合用保和散功效才更专一。然而必须详细审查损伤了什么食物，加入对症的药物，效果更好。
大顺饮 （见腹痛章节）。
痰火呃逆，用栀连二陈汤，但这适用于胃中没有停滞的情况。如果有食滞，又被寒冷抑制遏阻，应当用缩砂仁、草豆蔻温燥，以打开寒凝，厚朴、青皮辛散，以消散滞气，然后再合用平胃散和保和散。
温中平胃散 即平胃散加豆蔻、砂仁。
此方即大顺饮，加苍术去青皮。平胃散加砂仁、豆蔻，善于治疗胃家凝结停滞，但内部没有燥热的情况下可用。
理中汤 （见腹痛章节）。
阳证呃逆，则用栀连二陈汤；阴证呃逆，则用理中汤。虚阳上浮，加黄连作为向导。
The *Shanghan Lun* (Treatise on Cold Damage) mentions "yue" (hiccups/belching with sound) but not "e" (hiccup). According to the chapter on treating "yue" in the *Ling Shu* (Spiritual Pivot), stimulating the nose with grass to induce sneezing, after which breathing pauses, or rapidly pulling/guiding the patient, can immediately cure it. Startling the patient greatly also cures it. Deduced from this, these are the principles of external treatments for hiccup today. Medical texts erroneously name dry retching and "yue" as "ke ni" (cough with reverse flow of qi). "Ke ni" is named because coughing involves reverse flow of qi. "E" refers to stomach qi being disharmonious and rushing upward to produce sound; it is named based on the sound, hence called "e ni" (hiccup).
Regarding the symptoms of hiccup: if the body presents with alternating chills and fever, vomiting accompanied by hiccup, this indicates exterior pathogenic factors transmitting to the Shaoyang (Lesser Yang) channel. If the left pulse is floating and tight, with fever and no sweating, Qianghuo Chaihu Tang (Notopterygium and Bupleurum Decoction) is the primary formula. If there is sweating and a rapid pulse, Xiaochaihu Tang (Minor Bupleurum Decoction) combined with Qingdan Tang (Clear Gallbladder Decoction) is used. If there is internal heat and thirst, hiccup that comes and goes, frequent sweating, cracked lips, and constipation, with a deep and rapid right pulse, this is due to Yangming interior heat rushing upward; Gange Zhuru Tang (Pueraria and Bamboo Shavings Decoction) or Zhuru Qingwei Tang (Bamboo Shavings Stomach-Clearing Decoction) are indicated. If there is interior heat with fecal impaction, and all six pulses are rapid and large, Xiexin Tang (Drain the Epigastrium Decoction) or Liangge San (Cool the Diaphragm Powder) are used. If there are signs indicating purgation is necessary, Chengqi Tang (Order the Qi Decoction) is used. If there is stomach heat combined with deficiency, Renshen Jupi Zhuru Tang (Ginseng, Tangerina Peel, and Bamboo Shavings Decoction) is used. If there is much phlegm in the epigastrium and the right pulse is slippery and large, Erchen Zhuru Tang (Two-Aged [Aged Tangerina Peel and Pinellia] Decoction with Bamboo Shavings) plus Zhike (Aurantii Fructus) and Jiegeng (Platycodon Root) is used. If there is both phlegm and fire, with a deep and rapid pulse, Zhilian Erchen Tang (Coptis and Two-Aged Decoction) plus Gegen (Pueraria Root) and Zhuru (Bamboo Shavings) is used, or Daotan Tang (Abundant Phlegm Decoction) is administered. If food stagnation is in the middle jiao, and the qi-kou pulse is slippery, Pingwei Baohe San (Stomach-Pacifying and Harmony-Preserving Powder) is used. If cold-cooling herbs were mistakenly taken, resulting in deep and slow pulses throughout, with stagnation in the middle jiao, Dashun Yin (Greatly Smooth Drink) should be used to warm the middle, combined with Baohe San. If yin fire rushes upward causing hiccup, Zhibo Siwu Tang (Anemarrhena, Phellodendron, and Four Substances Decoction) is used. Additionally, if there is no fever at onset, no thirst, clear urination and defecation, deep and slow pulses throughout, yet hiccup appears, this is an yin-pattern cold hiccup. For mild cases, Lizhong Tang (Regulate the Middle Decoction) is used; for severe cases, Sini Tang (Reverse the Extremities Decoction); Dingxiang Shidi Tang (Clove and Persimmon Calyx Decoction) is also indicated.
In Yangming wind-stroke, the pulse is wiry, floating, and large, with shortness of breath, generalized abdominal fullness, pain in the hypochondrium and heart region, obstruction of qi upon prolonged pressing, dry nose, inability to sweat, drowsiness, jaundice of the whole body and face, difficulty in urination, tidal fever, and frequent hiccups. Swelling around the ears and temples may occur; acupuncture brings slight relief, but the exterior syndrome remains unresolved. If the disease persists beyond ten days and the pulse continues to float, Xiaochaihu Tang is given. If the pulse is merely floating without other symptoms, Mahuang Tang (Ephedra Decoction) is given. If there is no urination, abdominal fullness increases, and hiccups worsen, it is incurable.
In Yangming disease, a wiry pulse indicates Shaoyang involvement. A floating and large pulse indicates Taiyang involvement. Abdominal fullness, hypochondriac and cardiac pain are Shaoyang symptoms. Dry nose, inability to sweat, drowsiness, full-body jaundice, tidal fever, and frequent hiccups are Yangming symptoms. Swelling around the ears and temples, slight relief after acupuncture, unresolved exterior syndrome, persistence beyond ten days, and a continuing floating pulse indicate using Xiaochaihu Tang to guide Yangming pathogenic factors out through the Shaoyang channel. If the pulse is merely floating without other symptoms, Mahuang Tang is used to guide Yangming pathogenic factors out (Note: Text implies guiding out, though Mahuang Tang typically releases the exterior). Treat according to the method. If originally there was no urination, and abdominal fullness with worsening hiccups occurs, it is incurable.
In Yangming disease, if the patient cannot eat, attacking the heat will inevitably cause hiccups. The reason is deficiency-cold in the stomach. Because the person is fundamentally deficient, attacking heat will inevitably cause hiccups.
Yangming inability to eat has two categories: cold and heat. Heat in the stomach causing inability to eat: attacking the heat leads to recovery. Cold in the stomach causing inability to eat: attacking the heat inevitably causes hiccups. The following text clarifies these two categories.
It is also stated: A floating and slow pulse indicates exterior heat and interior cold. With diarrhea of undigested food, Sini Tang is the primary treatment. If the stomach is deficient and cold, unable to eat, drinking water will cause hiccups. This means that in Yangming interior cold with inability to eat, not only does taking cold medicines cause hiccups, but even drinking water causes them.
In cold damage, if there are hiccups and abdominal fullness, observe the anterior and posterior orifices to determine which is obstructed; unblocking it will lead to recovery.
This means that in Yangming stomach excess with hiccups and abdominal fullness, one should observe which of the anterior or posterior orifices is obstructed and unblock it.
**Qianghuo Chaihu Tang (Notopterygium and Bupleurum Decoction)**
Ingredients: Qianghuo (Notopterygii Rhizoma et Radix), Chaihu (Bupleuri Radix), Fangfeng (Saposhnikoviae Radix), Huangqin (Scutellariae Radix), Guangpi (Citri Reticulatae Pericarpium), Banxia (Pinelliae Rhizoma), Gancao (Glycyrrhizae Radix et Rhizoma).
Indications: Alternating chills and fever, vomiting, bitter taste, deafness, hypochondriac pain, and hiccup require treating the Shaoyang channel. If chills and headache are present, it involves both Shaoyang and Taiyang; thus, this formula treats both channels simultaneously.
**Xiaochaihu Tang (Minor Bupleurum Decoction)** (See section on Chills and Fever).
For Shaoyang-Taiyang hiccup, use the above formula to disperse the exterior. If there is no Taiyang exterior pathogen, use this formula plus Zhuru (Bambusa Shizhusu) and Houpo (Magnoliae Officinalis Cortex), effectively combining with Qingdan Tang.
**Chengqi Tang (Order the Qi Decoction)** (See section on Constipation).
**Xiexin Tang (Drain the Epigastrium Decoction)** (See section on Fullness and Oppression).
Phlegm-fire in the middle jiao, suppressed by cold-cooling herbs, often causes hiccup. This formula uses Huanglian (Coptidis Rhizoma) and Ganjiang (Zingiberis Rhizoma) together to regulate interior qi, assisted by Banxia to disperse phlegm-saliva with its acrid nature. If vomiting is present, add Zhuru and Huoxiang (Agastaches Herba); if qi reversal and obstruction exist, add Zhike and Houpo.
**Liangge San (Cool the Diaphragm Powder)** (See section on Mania).
All rebellious upward rushing belongs to fire. Therefore, for yang-pattern hiccup with heat but no stagnation, use this formula to clear it. If signs of downward purgation appear, add Xuanmingfen (Natrii Sulfas).
**Renshen Jupi Zhuru Tang (Ginseng, Tangerina Peel, and Bamboo Shavings Decoction)**
Ingredients: Jupi (Citri Reticulatae Pericarpium), Zhuru (Bambusa Shizhusu), Shengjiang (Zingiberis Rhizoma Recens), Houpo (Magnoliae Officinalis Cortex), Banxia (Pinelliae Rhizoma), Gancao (Glycyrrhizae Radix et Rhizoma), Renshen (Ginseng Radix et Rhizoma), Huoxiang (Agastaches Herba).
If hiccup accompanies exterior signs, disperse the exterior; if hiccup involves phlegm-fire, use Zhilian Zhuru Tang or Zhilian Erchen Tang; if cold and heat are unbalanced, use Banxia Xiexin Tang. Now, since the exterior pathogen has resolved and there is no interior excess heat, but only stomach deficiency causing hiccup, this formula tonifies the stomach and harmonizes the middle.
**Erchen Zhuru Tang (Two-Aged Decoction with Bamboo Shavings)**
Ingredients: Shu Banxia (Prepared Pinelliae Rhizoma), Bai Fuling (Poria), Guangpi (Citri Reticulatae Pericarpium), Gancao (Glycyrrhizae Radix et Rhizoma), Zhuru (Bambusa Shizhusu), Zhike (Aurantii Fructus), Jiegeng (Platycodonis Radix).
For stomach-heat hiccup, use Liangge San; for cold-heat imbalance, use Xiexin Tang; for stomach-deficiency hiccup, use Renshen Jupi Tang. Now, due to phlegm coagulation and qi obstruction, Erchen Tang is used with added Zhuru, Zhike, and Jiegeng. Zhilian Erchen Tang adds Gegen and Zhuru.
For vomiting and hiccup caused by stomach phlegm-fire, Zhilian Erchen Tang is used; adding Zhuru clears gallbladder fire, and Gegen disseminates stomach heat. It treats not only hiccup but also vomiting.
**Pingwei San (Stomach-Pacifying Powder)** (See section on Delirium).
Stomach dampness stagnation and food retention can also cause hiccup. Generally, if the right pulse is solid and large but not rapid, it indicates food-fullness hiccup; do not recklessly use cold-cooling herbs. For stomach excess, add Zhishi (Aurantii Fructus Immaturus), Laifuzi (Raphani Semen), and Qingpi (Citri Reticulatae Pericarpium Viride). For vomiting, add Banxia and Huoxiang.
**Baohe San (Harmony-Preserving Powder)** (See section in Chest Fullness).
For dampness stagnation and food retention, use the preceding Pingwei San, but it must be combined with Baohe San for more specific efficacy. However, one must carefully examine what food was ingested and add corresponding herbs for better effect.
**Dashun Yin (Greatly Smooth Drink)** (See section on Abdominal Pain).
For phlegm-fire hiccup, Zhilian Erchen Tang is used, but this applies only when there is no stagnation in the stomach. If there is food stagnation suppressed by cold, Suisha (Amomi Fructus Rotundus) and Cao Kou (Cardamomi Fructus) should be used for their warming and drying properties to open cold coagulation, while Houpo and Qingpi disperse stagnation with their acrid nature, followed by combining Pingwei San and Baohe San.
**Wenzhong Pingwei San (Warm-Middle Stomach-Pacifying Powder)** is Pingwei San plus Doukou (Cardamomi Fructus) and Sharen (Amomi Fructus).
This formula is essentially Dashun Yin with Cangzhu (Atractylodis Rhizoma) added and Qingpi removed. Pingwei San plus Sharen and Doukou effectively treats stomach coagulation and stagnation, provided there is no internal dry-heat.
**Lizhong Tang (Regulate the Middle Decoction)** (See section on Abdominal Pain).
For yang-pattern hiccup, use Zhilian Erchen Tang; for yin-pattern hiccup, use Lizhong Tang. If deficient yang floats upward, add Huanglian as a guiding herb.
**Sini Tang (Reverse the Extremities Decoction)** (See section on Cold Extremities).
For yin-pattern hiccup with cold extremities, use this decoction urgently.
**Zhibo Siwu Tang (Anemarrhena, Phellodendron, and Four Substances Decoction)**
For yin-fire hiccup, use this formula to astringe and descend; this is the method of nourishing yin and descending fire.
**Dingxiang Shidi Tang (Clove and Persimmon Calyx Decoction)**
Ingredients: Dingxiang (Caryophylli Flos), Shidi (Diospyri Calyx), Renshen (Ginseng Radix et Rhizoma), Shengjiang (Zingiberis Rhizoma Recens).
This is a formula for treating cold hiccup. Using it today to treat yang-pattern hiccup is a major error.
