Treats Shanghan (Cold Damage) where there is heat in the chest causing nausea, and cold in the stomach causing abdominal pain.
Huanglian (Coptidis Rhizoma, stir-fried), Ganjiang (Zingiberis Rhizoma, stir-fried), Guizhi (Cinnamomi Ramulus), Gancao (Glycyrrhizae Radix et Rhizoma, each 3 liang), Renshen (Ginseng Radix, 2 liang), Banxia (Pinelliae Rhizoma, 0.5 sheng), Dazao (Jujubae Fructus, 12 pieces).
This formula acts on the Foot-Yangming Stomach Meridian. Huanglian is bitter and cold, clearing heat to descend Yang; Ganjiang and Guizhi are acrid and warm, dispelling cold to ascend Yin; Renshen supports the healthy Qi to expel pathogenic factors; Banxia harmonizes the Stomach and stops vomiting; Gancao and Dazao regulate the Middle Jiao and relieve pain. When cold and heat contend in the Upper and Middle Jiaos, this formula is used to harmonize them (Yu Jiayan stated: In patients with dampness who were incorrectly treated with purgatives, if there is a coating on the tongue... Lian Tang... ask about purging... evil... Jiao belongs... [Note: The original text here is severely fragmented]).
(Zhang Zhongjing)
Treats combined disease of the Taiyang and Shaoyang meridians presenting with spontaneous diarrhea. (Combined disease refers to having symptoms of both Taiyang, such as fever, headache, and stiffness of the neck and back, and Shaoyang, such as deafness, hypochondriac pain, vomiting, bitter taste, and alternating chills and fever. Spontaneous diarrhea refers to diarrhea occurring without prior use of purgative therapy. While spontaneous diarrhea is often suitable for warming methods, if there are accumulations in the intestines and stomach, or exogenous heat in the Lower Jiao, warming agents alone cannot stop it; one may employ methods to separate clear from turbid or purge and drain. Cheng Wuji stated: Diarrhea due to combined disease of Taiyin and Yangming belongs to the exterior, treated with Gegen Tang to induce sweating; diarrhea due to combined disease of Shaoyang and Yangming involves yang pathogens entering the interior, treated with Chengqi Tang to purge; this case involves diarrhea due to combined disease of Taiyang and Shaoyang...)
Huangqin (Scutellariae Radix, 3 liang), Shaoyao (Paeoniae Radix Alba), Gancao (Glycyrrhizae Radix et Rhizoma, each 2 liang), Dazao (Jujubae Fructus, 12 pieces).
This formula acts on the Foot-Taiyang Bladder Meridian and Foot-Shaoyang Gallbladder Meridian. Cheng Wuji stated: For deficiency without fullness, bitter substances solidify, and sour substances astringe; the bitterness and sourness of Huangqin and Shaoyao solidify and astringe the Qi of the intestines and stomach; for weakness and insufficiency, sweet substances tonify; the sweetness of Gancao and Dazao tonifies the weakness of the intestines and stomach. (Wang Ang's note: Why not use herbs of both meridians for their combined disease? Because combined disease accompanied by diarrhea indicates yang pathogens have entered the interior; thus, priority is given to treating the interior. Therefore, Huangqin is used to clear the heat, while Gancao, Shaoyao, and Dazao harmonize the Taiyin Spleen. When the interior Qi is harmonized, the exterior symptoms resolve naturally. Harmonization methods are not limited to one approach. Zhang Zhongjing’s writings are precise; since this syndrome mentions only diarrhea, this formula treats only diarrhea. *Yixue Qiyuan* uses it for heat-dysentery with abdominal pain, renaming it Huangqin Shaoyao Tang; Li Dongyuan added Muxiang (Aucklandiae Radix), Binglang (Arecae Semen), Dahuang (Rhei Radix et Rhizoma), Huanglian (Coptidis Rhizoma), Guishao (Rosae Chinensis Fructus), and Guigui (Cinnamomi Cortex), renaming it Shaoyao Tang to treat dysentery; Zhang Zhongjing’s formula thus became the ancestral prescription for treating dysentery for all generations.)
Adding Banxia (Pinelliae Rhizoma, 0.5 sheng) and Shengjiang (Zingiberis Rhizoma Recens, 3 liang) to this base formula creates Huangqin Jia Banxia Shengjiang Tang (Zhang Zhongjing): Treats the aforementioned conditions accompanied by vomiting (vomiting is due to rebellious Stomach Qi; Banxia and Shengjiang are added to disperse rebellious Qi. *Qianjin Fang* states: Shengjiang is the sacred medicine for vomiting, dispersing rebellious Qi. *Jinkui Yaolue* states: Banxia is used for vomiting to remove fluid retention; once fluids are removed, vomiting stops, thereby descending phlegm-fluids); it also treats cough induced by the Gallbladder Fu-organ, characterized by vomiting bitter fluid like bile (rebellious Stomach Qi causes vomiting of bitter fluid; overflow of Gallbladder juice causes bitter taste).
Removing Dazao from this base formula creates Huangqin Shaoyao Tang: Treats epistaxis caused by rising fire and heat-dysentery.
*Waitai Miyao*’s Huangqin Tang: Huangqin (Scutellariae Radix), Renshen (Ginseng Radix), Ganjiang (Zingiberis Rhizoma, each 3 liang), Guizhi (Cinnamomi Ramulus, 1 liang), Banxia (Pinelliae Rhizoma, 0.5 jin), Dazao (Jujubae Fructus, 12 pieces): Treats dry heaving and diarrhea.
