蔚按。仲景凡下利证俱不用芍药。惟此方权用之以泄陷里之热。非定法也。
张令韶曰。此治太阳与少阳合病而下利与呕也。合者彼此协议。非如并者之归并于此也。
太阳主开。少阳主枢。太阳不能达枢以外出。而反从枢以内陷。故下利。与黄芩汤清陷里之

治疗太阳病与少阳病同时发病，没有腹泻但出现呕吐的证候。
黄芩（三两） 甘草（二两，炙烤） 芍药（二两） 半夏（半升） 生姜（三两） 大枣（十二枚）
以上六味药，用水一斗，煎煮至剩余三升，滤去药渣。每次温服一升，白天服两次，晚上服一次。
歌诀说：十二枚大枣守住成法准则，二两芍药、二两甘草、三两黄芩。若利用本方治疗伴有呕吐的情况需加味，加入生姜三两、半夏半升斟量使用。
蔚按语：张仲景凡是治疗下利（腹泻）的证候通常不使用芍药，唯独在此方中权且使用它来清泄陷入体内的热邪，这并不是固定的法则。
张令韶说：这是治疗太阳与少阳合病而出现下利和呕吐的方法。“合”是指彼此协同，不像“并”那样归属于一方。太阳主司开启，少阳主司枢机。太阳之气不能通过枢机向外透达，反而随着枢机向内陷入，所以导致下利。用黄芩汤清泄陷入体内的热邪，并将太阳之气通达于体表。如果发生呕吐，是少阳的枢机想要借助太阳的开启作用向上达出，因此加入半夏、生姜，宣通发散上逆的气机，以辅助太阳的开启功能。
治疗伤寒病，胸中有热邪，胃中有邪气干扰，腹部疼痛，想要呕吐的证候。此方主治。
黄连（三两） 甘草（二两，炙烤） 干姜（三两） 人参（二两） 桂枝（三两） 半夏（半升） 大枣（十二枚）
以上七味药，用水一斗，煎煮至剩余五升，滤去药渣。每次温服一升，白天服三次，晚上服两次。
歌诀说：腹痛呕吐借助枢机之力。（少阳为枢机。）二两人参、二两甘草、半升半夏。黄连、桂枝、干姜各三两，十二枚大枣妙处层层递进。（另一种版本记载甘草为三两。）
王晋三说：这就是小柴胡汤的变法，用桂枝代替柴胡，用黄连代替黄芩，用干姜代替生姜。胸中有热、呕吐、腹部疼痛的原因，全是因为胃中有邪气阻遏了阴阳升降的机制。因此用人参、大枣、干姜、半夏、甘草专门调和胃气，使药物进入胃后，依靠胃气的上下敷布，交通阴阳。再使用桂枝宣发太阳之气，载着黄连从上焦阳分清泻热邪，防止其深入太阴，以免妨碍虚寒性腹痛。
Treats the syndrome of simultaneous involvement of Taiyang (Greater Yang) and Shaoyang (Lesser Yang), characterized by spontaneous diarrhea. This formula is indicated.
Huangqin (Scutellariae Radix, 3 liang) Gancao (Glycyrrhizae Radix et Rhizoma, processed with honey, 2 liang) Shaoyao (Paeoniae Radix, 2 liang) Dazao (Jujubae Fructus, 12 pieces).
Take the above four herbs, add one dou of water, decoct to obtain three sheng. Remove the dregs. Take one sheng warm, twice during the day and once at night.
Treats the syndrome of simultaneous involvement of Taiyang and Shaoyang, characterized by vomiting without diarrhea.
Huangqin (Scutellariae Radix, 3 liang) Gancao (Glycyrrhizae Radix et Rhizoma, processed with honey, 2 liang) Shaoyao (Paeoniae Radix, 2 liang) Banxia (Pinelliae Tuber, half sheng) Shengjiang (Zingiberis Rhizoma Recens, 3 liang) Dazao (Jujubae Fructus, 12 pieces).
Take the above six herbs, add one dou of water, decoct to obtain three sheng. Remove the dregs. Take one sheng warm, twice during the day and once at night.
The song states: Twelve Jujube fruits maintain the established principle; two liang each of Paeonia and Glycyrrhiza, three liang of Scutellaria. When utilizing this base formula for cases with added vomiting, add three liang of Zingiber and half a sheng of Pinellia.
Commentary by Wei: Zhang Zhongjing generally does not use Paeonia in cases of diarrhea. Only in this formula is it used provisionally to drain heat sinking into the interior. This is not a fixed rule.
Zhanglingshao stated: This treats simultaneous involvement of Taiyang and Shaoyang presenting with diarrhea and vomiting. "Simultaneous involvement" implies mutual coordination, unlike "concurrent involvement" where pathogens merge into one aspect. Taiyang governs opening, while Shaoyang governs the pivot. If Qi of Taiyang cannot reach the pivot to emerge outward, it instead sinks inward following the pivot, resulting in diarrhea. Huangqin Tang clears heat sinking into the interior and directs Taiyang Qi outward. In cases of vomiting, the pivot of Shaoyang desires to ascend via the opening function of Taiyang. Therefore, Pinellia and Zingiber are added to disperse and direct rebellious Qi, assisting the opening function of Taiyang.
Treats Cold Damage syndrome where there is heat in the chest, pathogenic factors in the stomach, abdominal pain, and a desire to vomit. This formula is indicated.
Huanglian (Coptidis Rhizoma, 3 liang) Gancao (Glycyrrhizae Radix et Rhizoma, processed with honey, 2 liang) Ganjiang (Zingiberis Rhizoma, 3 liang) Renshen (Ginseng Radix, 2 liang) Guizhi (Cinnamomi Ramulus, 3 liang) Banxia (Pinelliae Tuber, half sheng) Dazao (Jujubae Fructus, 12 pieces).
Take the above seven herbs, add one dou of water, decoct to obtain five sheng. Remove the dregs. Take one sheng warm, three times during the day and twice at night.
The song states: Abdominal pain and vomiting rely on the pivot mechanism. (Shaoyang serves as the pivot.) Two liang each of Ginseng and Glycyrrhiza, half a sheng of Pinellia. Coptis, Cinnamon Twig, and Dried Ginger are each three liang; twelve Jujube fruits offer layered benefits. (Another version records Glycyrrhiza as three liang.)
Wang Jin-san stated: This is a modified form of Xiao Chaihu Tang (Minor Bupleurum Decoction), using Cinnamon Twig to replace Bupleuri Radix, Coptis to replace Scutellariae Radix, and Dried Ginger to replace Fresh Ginger. The causes of heat in the chest, vomiting, and abdominal pain are entirely due to pathogenic factors in the stomach obstructing the mechanism of ascending and descending of Yin and Yang. Therefore, Ginseng, Jujube, Dried Ginger, Pinellia, and Glycyrrhiza are used specifically to harmonize Stomach Qi. After entering the stomach, they rely on the distribution of Stomach Qi to facilitate communication between Yin and Yang. Subsequently, Cinnamon Twig is used to disseminate Taiyang Qi, carrying Coptis to clear heat from the Upper Jiao Yang aspect, preventing it from sinking deeper into Taiyin, which would otherwise aggravate deficiency-cold abdominal pain.
