Treats the condition where, after the resolution of Taiyang disease (Taiyang Disease) through sweating, vomiting, or purging, there is epigastric fullness and hardness, with persistent belching.
Xuanfuhua (Inulae Flos, 3 liang), Daizheshi (Hematitum, 1 liang), Shengjiang (Zingiberis Rhizoma Recens, 5 liang, sliced), Dazao (Jujubae Fructus, 12 pieces), Renshen (Ginseng Radix et Rhizoma, 2 liang), Banxia (Pinelliae Rhizoma Preparatum, half sheng), Gancao (Glycyrrhizae Radix et Rhizoma Praeparata cum Melle, 3 liang, honey-fried). Use one dou of water, decoct to six sheng, remove dregs, and decoct again to obtain three sheng. Take warm, divided into three doses daily.
Xuanfu Daizhe Tang consists of Renshen, Banxia, Shengjiang, Gancao, and Dazao. Heavy substances like Daizheshi are used to suppress rebellious Qi, while Xuanfuhua's salty flavor softens stagnation. This formula has the power to relieve epigastric hardness and belching.
The *Lingshu: Kouwen* chapter states: "When cold pathogen lodges in the Stomach, rebellious Qi scatters upward from below and re-emerges from the Stomach, thus causing belching." The *Suwen: Xuanming Wuqi* chapter states: "The Heart is associated with belching." Belching is a sound arising from pathology in the Upper Jiao (Upper Burner). When the Spleen loses its ascending function and the Lung loses its descending function, Yin excess moves into the Stomach, associates with the Heart to produce sound, commonly known as "belching" (Oxygen eructation). Therefore, Xuanfuhua is used for its salty nature to descend Lung Qi; Daizheshi is used for its heavy nature to calm the Qi of the Pericardium; Banxia is used to unblock Stomach Qi; Shengjiang and Dazhao are used to disseminate Spleen Qi; and Renshen and Gancao are used to stabilize the Middle Jiao Yang, so that Yin and Yang ascend and descend according to their normal rhythm, thereby eliminating epigastric hardness and belching completely.
Belching is commonly called burping. If accompanied by diarrhea, one should look to the Xiexin Tang (Drain the Epigastrium Decoction) formulas. (This is roughly similar to the previously mentioned Xiexin methods. Wang Ang's *Yifang Jijie* cites *Bencao Gangmu*: "For post-illness epigastric hardness and belching without diarrhea, use this decoction; if there is diarrhea, use Shengjiang Xiexin Tang.") This formula calms Yin, disseminates Yang, and supports weak Stomach Qi; it is also suitable for hiccup (Hiccough) and regurgitation (Regurgitation). (This is a formula that calms Yin and disseminates Yang. Hiccups and regurgitation are both caused by rebellious Qi in the Upper and Middle Jiaos failing to descend. Using this formula to calm Yin Qi and disseminate Stomach Yang allows the Upper and Middle Jiaos to achieve harmony.)
Treats Shaoyang-Taiyang Hebing (Combined Disease of Shaoyang and Taiyang) presenting with spontaneous diarrhea.
Huangqin (Scutellariae Radix, 3 liang), Gancao (Glycyrrhizae Radix et Rhizoma Praeparata cum Melle, prepared), Shaoyao (Paeoniae Radix Alba, 2 liang each), Dazao (Jujubae Fructus, 12 pieces). Use one dou of water, decoct to obtain three sheng, remove dregs, and take one sheng warm.
