在黄芩汤的方剂基础上，加入洗净的半夏半升、生姜三两。其余部分均依照黄芩汤的服用方法执行。
太阳病与少阳病同时发病（合病），出现自发性腹泻的，给予黄芩汤治疗；如果伴有呕吐症状的，使用黄芩加半夏生姜汤。按语：呕吐也属于少阳病的证候，因此加入半夏和生姜来止呕，这也就是小柴胡汤的加减用法。
干姜、黄连、黄芩、人参（各三两）
以上四味药，用水六升，煎煮至剩余二升，滤去药渣，分两次温服。
伤寒病原本就有虚寒性腹泻，医生又误用吐法或下法治疗，导致寒热格拒，反而加重了呕吐和腹泻。如果食物刚入口就立即吐出，应用干姜黄连黄芩人参汤主治。
按语：此证属于阴寒之气格拒于内，排斥阳气于外。用干姜来开通阴寒，用黄芩和黄连来清泄阳热，再用人参来鼓动助益胃气，并且可以辅助干姜的辛温之性，冲开阴邪，使得格拒解除而呕吐自然停止。
旋复花（三两）、代赭石（一两）、人参（二两）、生姜（五两，切块）、半夏（半升，洗净）、甘草（三两，炙烤）、大枣（十二枚，掰开）
以上七味药，用水一斗，煎煮至剩余六升，滤去药渣，再次煎煮浓缩至三升，每次温服一升，每日服用三次。
伤寒经过发汗、催吐或泻下治疗后，病邪虽解，但出现心下部痞塞胀硬，嗳气持续不除的症状，应用旋复代赭汤主治。按语：心下部痞塞胀硬，是因为中焦虚弱且有留滞之邪；嗳气持续不除，是胃气上逆且兼有停饮所致。主用旋复花引导痰饮下行，代赭石镇心安神、降逆止呕，而对于留滞的邪气，再用生姜和半夏来宣散开通；对于逆乱的气机，用人参、甘草和大枣来调和。待正气恢复、邪气消散，则痞满可解，嗳气也会停止。
浓朴（半斤，去皮，炙烤）、生姜（半斤，切块）、半夏（半升，洗净）、人参（一两）、甘草（二两，炙烤）
以上五味药，用水一斗，煎煮至剩余三升，滤去药渣，温服一升，每日服用三次。
发汗治疗后，出现腹部胀满的症状，应用浓朴生姜半夏人参汤主治。按语：发汗后阳气虚弱，不能化生运行气机，阴寒邪气结聚于内，壅滞而导致胀满。本方主要用浓朴来消除胀满，而生姜、半夏、人参、甘草都能醒脾开胃、调和脾胃，使气机得以运行化散，胀满自然消除。
In the formula of Huangqin Tang (Scutellaria Decoction), add Banxia (Pinelliae Rhizoma, 半夏) half a sheng (a unit of volume) after washing, and Shengjiang (Zingiberis Rhizoma Recens, 生姜) three liang. Follow the administration method of Huangqin Tang for the rest.
When Taiyang disease (disease of the Taiyang channel) and Shaoyang disease (disease of the Shaoyang channel) occur simultaneously (Hebing, combined disease), and spontaneous diarrhea occurs, administer Huangqin Tang. If vomiting is present, use Huangqin Jia Banxia Shengjiang Tang (Scutellaria Decoction with Added Pinellia and Fresh Ginger). Note: Vomiting also belongs to Shaoyang syndrome; therefore, Banxia and Shengjiang are added to stop vomiting, which is also the method of modification of Xiaochaihu Tang (Minor Bupleurum Decoction).
Ganjiang (Zingiberis Rhizoma, 干姜), Huanglian (Coptidis Rhizoma, 黄连), Huangqin (Scutellariae Radix, 黄芩), Renshen (Ginseng Radix et Rhizoma, 人参) (each three liang).
The above four ingredients are boiled in six sheng of water until two sheng remain. Strain the dregs, and divide into two warm doses.
In Shanghan (Cold Damage disease), if there was originally cold-type diarrhea, and the physician erroneously applied emesis or purgation, the resulting cold-heat rejection aggravates vomiting and diarrhea. If food is vomited immediately upon entering the mouth, Ganjiang Huanglian Huangqin Renshen Tang (Ginger, Coptis, Scutellaria, and Ginseng Decoction) is indicated.
Note: This syndrome involves Yin cold rejecting within and repelling Yang outward. Ganjiang opens the Yin cold, while Huangqin and Huanglian drain the Yang heat. Renshen is used to stimulate and assist Stomach Qi, and can also aid the acrid-warm nature of Ganjiang to break through the Yin pathogen, allowing the rejection to resolve and vomiting to cease spontaneously.
Xuanfuhua (Inulae Flos, 旋复花) (three liang), Daizheshi (Ochre, 代赭石) (one liang), Renshen (two liang), Shengjiang (five liang, sliced), Banxia (half a sheng, washed), Gancao (Glycyrrhizae Radix et Rhizoma, 甘草) (three liang, honey-fried), Dazao (Jujubae Fructus, 大枣) (twelve pieces, split).
The above seven ingredients are boiled in ten dou of water until six sheng remain. Strain the dregs, and decoct again until three sheng remain. Take one sheng warm, three times daily.
After Shanghan has been resolved by sweating, emesis, or purgation, if epigastric fullness and hardness persist, accompanied by unrelenting belching, Xuanfu Daizhe Tang (Inula and Hematite Decoction) is indicated. Note: Epigastric fullness and hardness indicate deficiency in the Middle Jiao with lingering pathogens. Unrelenting belching indicates rebellious Stomach Qi combined with retained fluid retention. Xuanfuhua guides the fluid downward, and Daizheshi calms the Heart and descends rebellion. For the lingering pathogens, Shengjiang and Banxia are used to open them up. For the rebellious Qi, Renshen, Gancao, and Dazao are used to harmonize. When deficiency is restored and pathogens dissipate, the fullness resolves and belching stops.
Houpo (Magnoliae Officinalis Cortex, 浓朴) (half a jin, bark removed, fried), Shengjiang (half a jin, sliced), Banxia (half a sheng, washed), Renshen (one liang), Gancao (two liang, fried).
The above five ingredients are boiled in ten dou of water until three sheng remain. Strain the dregs, take one sheng warm, three times daily.
After sweating therapy, if abdominal fullness occurs, Houpo Shengjiang Banxia Renshen Tang (Magnolia Twig, Fresh Ginger, Pinellia, and Ginseng Decoction) is indicated. Note: After sweating, Yang Qi is deficient and unable to transform Qi, leading to the internal knotting of Yin pathogens and congestion causing fullness. The formula primarily uses Houpo to remove fullness, while Shengjiang, Banxia, Renshen, and Gancao awaken the Stomach and harmonize the Spleen, allowing Qi to transform and fullness to disappear spontaneously.
