巢氏《病源》云∶荣卫俱虚，气血不足，停水积饮在胃脘则脏冷。脏冷则脾不磨，
脾不磨则宿谷不化，其气逆而成反胃也。则朝食暮吐，暮食朝吐，心下牢大如杯，往来寒热，
甚者食已即吐。其脉紧而弦，紧则为寒，弦则为虚，虚寒相搏，故食已则吐，名为反胃。
《金匮》云∶病患脉数，数则为热，当消谷引食而反吐者，以发其汗，令阳微，膈气虚，
肺乃数，数为客热，不能消谷，胃中虚冷故也。脉弦者虚也，胃气无余，朝食暮吐，变
为反胃，寒在于上，医反下之，令脉反弦，故名曰虚。
《玉机微义》云∶反胃之证，其始也，或由饮食不节，痰饮停滞，或因七情过用，
脾胃内虚而作。古方不察病因，悉指为寒，用香燥大热之药治之。夫此药止能散寒邪行滞气，
其于饮食痰积勿能祛逐。七情之火反有所炽，脾胃之阴反有所耗。是以药助病邪，日以深痼。
脾气渐虚，不能运化，故食久而复出，有实时吐出，皆为正气不完。辛香之药，尽是治标，当
扶助正气，健脾和胃，是为治本，而疾可瘳。

巢元方在《诸病源候论》中说：营气与卫气都虚弱，气血不足，水饮停滞在胃脘部位就会导致脏腑寒冷。脏腑寒冷则脾脏无法运化食物，脾不运化则宿食不能消化，气机上逆从而形成反胃症。表现为早晨吃的东西晚上吐出来，晚上吃的东西早上吐出来，心窝部坚硬如杯状，伴有忽冷忽热的症状，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，所以进食后即呕吐，称为反胃。
《金匮要略》说：病人脉数，数脉主热，应当消谷善饥且食欲旺盛，反而出现呕吐，这是因为发汗过度，导致阳气微弱，胸膈之气虚弱，肺脉变数。数为客热，不能消化食物，原因是胃中虚冷。脉弦代表虚证，胃气已无余存，早晨吃的晚上吐，演变为反胃，寒邪在上焦，医生反而使用攻下法，导致脉象反见弦象，所以名为虚证。
《玉机微义》说：反胃这一病症，起初可能由于饮食不节制，痰饮停滞，或者因为七情（喜、怒、忧、思、悲、恐、惊）过度使用，导致脾胃内部虚弱而发病。古代医方没有仔细考察病因，一概将其归为寒证，使用芳香燥烈的大热药物治疗。这类药物只能驱散寒邪、行滞气，对于饮食积滞和痰积却无法祛除。反而会使七情之火更加炽盛，耗伤脾胃之阴。因此，药物助长了病邪，使病情日益深重顽固。脾气逐渐虚弱，不能运化水谷，所以食物停留很久后再次吐出，有的即时吐出，这都是正气不完备的表现。辛香类药物都是治标之法，应当扶助正气，健脾和胃，这才是治本之道，疾病才能痊愈。

Chao Yuanfang stated in *Zhu Bing Yuan Hou Lun* (Source Book of All Diseases): When Ying Qi (Nutritive Qi) and Wei Qi (Defensive Qi) are both deficient, and Qi and Blood are insufficient, retained water and fluid accumulate in the Stomach House (epigastrium), causing coldness in the Zang organs. Coldness in the Zang organs impairs the Spleen's ability to transform and transport food. If the Spleen fails to transform, undigested food remains stagnant, leading to rebellious Qi that results in Fan Wei (Reverse Vomiting). Symptoms include vomiting food eaten in the morning by evening, or food eaten in the evening by morning. There is a sensation of hardness in the epigastrium, large as a cup, accompanied by alternating chills and fever. In severe cases, vomiting occurs immediately after eating. The pulse is tight and wiry. A tight pulse indicates Cold, while a wiry pulse indicates Deficiency. The interplay of Deficiency and Cold causes vomiting after eating, hence named Fan Wei.
The *Jin Gui Yao Lue* (Essential Prescriptions from the Golden Cabinet) states: If a patient has a rapid pulse, which indicates Heat, they should normally digest food well and have an increased appetite. However, if vomiting occurs instead, it is because excessive sweating has depleted Yang Qi, leaving the Diaphragm Qi weak and the Lung Qi rapid. Rapidness here represents "Guest Heat," which cannot digest food, due to empty Cold in the Stomach. A wiry pulse indicates Deficiency; there is no surplus of Stomach Qi. Morning food vomited by evening transforms into Fan Wei. Cold resides in the Upper Jiao, but the physician incorrectly used purgatives, causing the pulse to become wiry. Thus, it is named Deficiency.
*Yu Ji Wei Yi* (Subtle Meanings of the Jade Machine) states: The onset of Fan Wei may stem from irregular diet causing Phlegm-Fluid retention, or from excessive emotional activity leading to internal deficiency of the Spleen and Stomach. Ancient formulas often failed to investigate the etiology, categorizing all cases as Cold and treating them with aromatic, drying, and intensely hot herbs. Such drugs can only disperse Cold pathogens and move stagnant Qi; they cannot eliminate dietary accumulations or Phlegm. Consequently, Fire from the Seven Emotions may flare up, and Yin of the Spleen and Stomach may be consumed. Thus, the medication aids the pathogen, making the condition increasingly deep-seated and stubborn. As Spleen Qi gradually weakens and fails to transform and transport, food remains for a long time before being vomited out, sometimes immediately. This reflects incomplete Righteous Qi (Zheng Qi). Acrid and aromatic herbs treat only the branch symptoms. One must support Righteous Qi, strengthen the Spleen, and harmonize the Stomach to address the root cause, thereby curing the disease.
