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。

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.
