The original text mentions: "After sweating due to febrile diseases, vomiting and diarrhea, if there is a hard lump under the heart and belching after the symptoms are relieved, Xuan Fu Dai Zhe Tang is the main treatment." This passage describes the main application scenario of this prescription: due to the reverse of qi in the stomach due to deficiency, hard lump under the heart and belching.

Then the hard and lumpy feeling under the heart can be eliminated and belching and hiccups can be stopped.
Pathogenesis of Xuan Fu Dai Zhe Tang
The pathogenesis of Xuan Fu Dai Zhe Tang is mainly related to weak stomach qi and internal obstruction of phlegm. When the human body is invaded by external evil, although the external evil can be eliminated through treatment methods such as sweating, vomiting or diarrhea, these methods may damage the spleen and stomach, leading to spleen and stomach dysfunction, internal generation of phlegm and obstruction in the middle burner. In this case, the stomach qi is not harmonious and the qi is blocked, which will cause symptoms such as hardness under the heart and belching. Its main symptoms include hardness under the heart, belching, or nausea and vomiting, spitting saliva, pale tongue, white and slippery tongue coating, and stringy and weak pulse.
In the Five Elements theory, the liver wood overcomes the stomach earth. When the stomach qi is weak, the liver qi can easily take advantage of the weakness and enter, leading to liver-stomach qi reversal. This qi reversal phenomenon can cause frequent belching, even vomiting and hiccups. The main medicinal materials in Xuan Fu Dai Zhe Tang, Inula flower and Daizhe stone, are aimed at this pathogenesis, and relieve these symptoms by reducing adverse reactions and resolving phlegm, calming the liver and reducing adverse reactions.
In short, the pathogenesis of Xuan Fu Dai Zhe Tang can be summarized as "stomach deficiency, phlegm blocking, liver and stomach qi reversal". This pathogenesis makes this prescription have a significant therapeutic effect in the treatment of middle deficiency, phlegm blocking and qi reversal syndrome. By resolving phlegm and lowering reverse qi, and replenishing qi and tonifying deficiency, it can achieve the effect of eliminating phlegm, calming reverse qi, and restoring middle deficiency.
