荣卫俱虚，其血气不足，停水积饮在胃脘则脏冷，脏冷则脾不磨，脾不磨则宿谷不化，
其气逆而成胃反也。则朝食暮吐，暮食朝吐，心下牢，大如杯，往往寒热，甚者食已即吐。
其脉紧而弦，紧则为寒，弦则为虚，虚寒相搏，故食已即吐，名为胃反。
荣卫不调，阴阳痞隔，若阳气虚，阴气盛，则生寒冷之病。今阴气虚、阳气实，故身体
五脏皆生热，其状吸吸而热，唇口干，小便赤也。
肺主气，为五脏上盖。气主皮毛，故易伤于风邪。风邪伤于腑脏，而血气虚弱，又因劳
役，大汗之后，或经大下，而亡津液，津液竭绝，肺气壅塞，不能宣通诸脏之气，因成肺萎
也。其病咳唾而呕逆涎沫，小便数是也。咳唾咽燥，欲饮者，必愈。欲咳而不能咳，唾干沫
而小便不利者，难治。
诊其寸口脉数，肺萎也，甚则脉浮弱。
呕哕之病者，由脾胃有邪，谷气不治所为也。胃受邪气，逆则呕；脾受邪气，脾胀气逆
，遇冷折之，气逆不通则哕也。
脾胃俱虚，受于风邪，故令新谷入胃，不能传化，故谷之气与新谷相干，胃气则逆，胃
逆则脾胀气逆，因遇冷折之，则哕也。
右手关上脉沉而虚者，善哕也。
呕吐者，皆由脾胃虚弱，受于风邪所为也。若风邪在胃，则呕；膈间有停饮，胃内有久
寒，则呕而吐。其状∶长大息，心里澹澹然，或烦满而大便难，或溏泄，并其候也。其汤熨
针石，别有正方，补养宣导，今附于后。
《养生方》云∶八月勿食姜，一云被霜瓜，向冬发寒热及温病，食欲吐，或心中停饮不
消，或为反胃。
《养生方·导引法》云∶正坐，两手向后捉腕，反向拓席，尽势，使腹弦弦，上下七，
左右换手亦然。除腹肚冷风、宿气积、胃口冷、食饮进退吐逆不下。
又云∶偃卧，展两胫、两手，左右跷两足踵，以鼻纳气，自极七息。除腹中病，食苦呕
又云∶坐，直舒两脚，以两手挽两足，自极十二通。愈肠胃不能受食，吐逆。以两手直
叉两脚底，两脚痛，舒。以头抵膝上，自极十二通。愈肠胃不能受食，吐逆。
荣气和卫气都虚弱，导致血气不足。如果水饮停滞积聚在胃脘部，就会使脏腑寒冷；脏腑寒冷则脾脏无法运化食物；脾脏不能运化，则隔宿的谷物无法消化。此时气机上逆，从而形成胃反病（以朝食暮吐、暮食朝吐为特征的疾病）。表现为早晨吃的东西晚上吐出来，晚上吃的东西早晨吐出来，心下部位坚硬，大小如杯状，时常伴有寒热症状，严重的甚至吃完就吐。脉象紧而弦，紧脉主寒，弦脉主虚，虚与寒相互搏结，所以进食后即吐，这种病称为胃反。
荣卫之气不调和，阴阳之气痞塞阻隔。如果阳气虚弱，阴气偏盛，就会产生寒冷的病症。如今是阴气虚弱、阳气偏实，所以身体五脏都会产生热象，其症状表现为呼吸间感觉发热，嘴唇和口干，小便颜色深红。
肺主管气，是五脏之上的覆盖物。气主要分布于皮毛，所以容易受到风邪侵袭。风邪侵入腑脏，加之血气虚弱，又因为过度劳累，在大汗之后，或者经过剧烈的泻下治疗，导致津液耗竭。津液枯竭，肺气壅塞，不能宣通其他脏腑的气机，因而形成肺萎（肺叶枯萎不用的病证）。该病的症状是咳嗽、吐唾沫并伴有呕吐涎沫，小便频数。如果咳嗽吐唾时咽喉干燥，想要喝水的，预示病情将愈。如果想咳嗽却咳不出来，吐出干沫且小便不利的，则难以治疗。诊察寸口脉象若见数脉，是肺萎的表现，严重时脉象浮而弱。
干呕，是由于胃气上逆的缘故。只是有呕吐的感觉想要吐，但吐出来却没有东西，所以称之为干呕。
呕吐和哕（呃逆）的病，是因为脾胃受到邪气干扰，谷气不能正常运行的原因所致。胃受到邪气，气机上逆则发生呕吐；脾受到邪气，脾胀气逆，如果遇到寒气遏制，气机逆乱不通则发生哕（呃逆）。
脾胃都虚弱，受到风邪侵袭，所以新的食物进入胃后，不能被传化和吸收，谷气与新入的食物相互干扰，导致胃气上逆；胃气上逆进而导致脾胀气逆，如果再遇到寒气遏制，就会发生哕（呃逆）。右手关部脉象沉而虚弱的，容易发生哕（呃逆）。
呕吐，都是由于脾胃虚弱，受到风邪侵袭所致。如果风邪在胃，就会呕吐；膈间有停积的水饮，胃内有久存的寒气，就会呕吐并吐出食物。其症状表现为：长叹气，心中悸动不安，或者烦闷胀满且大便困难，或者溏泄，这些都是相应的征候。关于汤药熨贴、针刺砭石的治疗方法，另有专门的方剂，补养和导引的方法，现在附在后面。
《养生方》说：八月不要吃姜，另一种说法是被霜打的瓜，到了冬天会引发寒热及温病，食欲减退想吐，或者心中停积的水饮不消散，或者导致反胃。
《养生方·导引法》说：端正坐好，双手向后握住手腕，反向用力撑开席子，尽力而为，使腹部肌肉紧绷，上下活动七次，左右换手同样操作。可以消除腹部的冷风、宿积之气、胃口的寒冷以及饮食进退引起的呕吐逆气不下。
又说：仰卧，伸展两腿和两手，左右交替跷起脚后跟，用鼻子吸气，尽力做七次呼吸。可以消除腹中的疾病，吃苦味食物引发的呕吐。
又说：坐着，伸直双腿，用双手挽住双脚，尽力做十二次。可以治愈肠胃不能受纳食物、呕吐逆气的症状。用双手直接交叉按住两脚底，感到脚痛后放松。用头抵住膝盖上方，尽力做十二次。可以治愈肠胃不能受纳食物、呕吐逆气的症状。
When Ying (Nutrient) Qi and Wei (Defensive) Qi are both deficient, blood and qi become insufficient. If water retention accumulates in the epigastrium, it causes coldness in the zang organs; when the zang organs are cold, the Spleen fails to digest food; if the Spleen cannot digest, retained grain remains undigested. The qi then rebels upward, resulting in Wei Fan (Gastric Reversal), a condition characterized by vomiting food eaten in the morning in the evening, or food eaten in the evening in the morning. Symptoms include hardness in the epigastrium, roughly the size of a cup, frequent alternating chills and fever, and in severe cases, immediate vomiting after eating. The pulse is tight and wiry: tight indicates Cold, wiry indicates Deficiency. The combination of Deficiency and Cold causes vomiting immediately after eating, named Wei Fan.
When Ying and Wei Qi are disharmonious, and Yin and Yang Qi are blocked and separated: if Yang Qi is deficient and Yin Qi is excessive, cold diseases arise. However, if Yin Qi is deficient and Yang Qi is excessive, heat arises in all five zang organs of the body. The presentation includes a sensation of heat during respiration, dry lips and mouth, and dark red urine.
The Lung governs Qi and serves as the canopy over the five zang organs. Qi primarily distributes to the skin and hair, making one susceptible to Wind pathogenic factors. When Wind invades the fu and zang organs, compounded by weak blood and qi, excessive labor, profuse sweating, or severe purgation that depletes body fluids, the Lung Qi becomes obstructed and cannot circulate Qi among the other organs, leading to Fei Wei (Lung Withering). Symptoms include coughing with expectoration of saliva and froth, accompanied by vomiting of salivary foam and frequent urination. If the patient experiences dry throat while coughing and expects to drink, recovery is likely. If the patient desires to cough but cannot, spits dry froth, and has difficult urination, the condition is difficult to treat. Palpation of the Cun Kou (radial artery) showing a rapid pulse indicates Fei Wei; in severe cases, the pulse may be floating and weak.
Dry heaving (Gan Ou) occurs due to rebellious Stomach Qi. It is termed dry heaving because there is the urge to vomit, yet nothing is expelled.
Diseases of vomiting and Yue (hiccups/belching) result from pathogenic factors affecting the Spleen and Stomach, disrupting the normal movement of Grain Qi. When the Stomach is affected by pathogens, rebellious Qi causes vomiting; when the Spleen is affected, Spleen distension and rebellious Qi occur. If this is constrained by Cold, causing Qi rebellion and obstruction, Yue results.
When both the Spleen and Stomach are deficient and invaded by Wind, newly ingested grain cannot be transformed and transported. The Qi of the grain interferes with the new grain, causing Stomach Qi to rebel. Stomach rebellion leads to Spleen distension and Qi rebellion; if constrained by Cold, Yue occurs. A deep and deficient pulse at the Guan position on the right hand indicates a tendency toward Yue.
Vomiting is caused by Spleen and Stomach deficiency and invasion by Wind pathogenic factors. If Wind is in the Stomach, vomiting occurs; if fluid retention exists between the diaphragm and chronic Cold resides in the Stomach, vomiting and regurgitation of food occur. Symptoms include frequent sighing, palpitations (Dan Dan), irritability and fullness with difficulty in defecation, or loose stools. These are the corresponding signs. Treatments involving decoctions, moxibustion/heat application, acupuncture, and stone therapy have separate specific formulas. Nourishing and Daoyin (guiding and pulling) methods are appended below.
The *Yangsheng Fang* states: Do not eat ginger in the eighth month; alternatively, avoid melons struck by frost. In winter, this may induce chills, fever, warm diseases, loss of appetite with nausea, persistent fluid retention in the heart region, or gastric reversal.
The *Yangsheng Fang · Daoyin Fa* states: Sit upright, grasp your wrists with both hands behind your back, and push backward against the mat with maximum effort, tightening the abdominal muscles. Perform this up and down seven times, switching hands for the left-right variation. This eliminates cold wind in the abdomen, accumulated stagnant Qi, cold in the stomach opening, and vomiting/regurgitation due to dietary irregularities.
It also states: Lie supine, extend both legs and arms, alternately lift the heels, inhale through the nose, and perform this maximally for seven breaths. This eliminates abdominal diseases and vomiting induced by bitter foods.
Furthermore: Sit, straighten both legs, grasp both feet with both hands, and perform this maximally twelve times. This cures inability of the intestines and stomach to accept food and vomiting/regurgitation. Cross both hands directly under the soles of the feet until pain is felt, then relax. Rest the head on the knees and perform this maximally twelve times. This cures inability of the intestines and stomach to accept food and vomiting/regurgitation.
