治前证兼呕者；亦治胆咳，咳呕苦水如胆汁。
黄芩汤原方加半夏半升，生姜三两，余同法。
黄芩汤用甘芍并，二阳合利枣加烹。（按∶太、少二阳合病，何以不用太、少两经之药？
盖合
苦，泄少阳之热，甘、芍、大枣酸甘，和太阴之气，使半里清而半表自解，和解之法，非一

在半表半里，非汗下所宜，故与黄芩汤，以和解半表半里之邪。”）此方遂为治痢祖，（利，
泄泻也。痢，滞下也。）后人加味或更名。（刘完素黄芩芍药汤、芍药汤，皆从此方化出，遂
为万世治痢之祖方矣。）再加生姜与半夏，（名黄芩加半夏生姜汤）下利兼呕此能平。（下利
即专于治利，不杂以风寒表药，此亦急当救里之义。若呕亦即兼以止呕之药，见证施治，古
人每不出此。倘服药后而本证愈，续见他证，则仍见证施治，可推而知也。）亦治胆咳呕苦
汁，（胃气逆则呕，胆汁热则苦。）苦泄辛通法最精。（酸苦泄热，辛甘和胃，胃气和，胆热
清，咳而呕苦自已。）

黄芩 芍药（各一两） 甘草（五钱） 水煎，温服。
治疗上述证候兼有呕吐症状的；也用于治疗胆咳，表现为咳嗽、呕吐苦水如同胆汁。
黄芩汤原方中加入半夏半升，生姜三两，其余煎服方法相同。
黄芩汤由甘草、芍药组成，在二阳合病下利的情况下加入大枣同煮。（按语：太阴、少阳两经合病，为何不使用这两条经络的药物？因为合用苦味药可以泄去少阳之热，甘味、芍药、大枣的酸甘之性，能够调和太阴之气，使半里清利而半表自然解除，和解的方法，并非只有一种。所谓合病，是指既有太阳病的头项痛、腰脊强直的症状，又有少阳病的耳聋、胁痛、口苦、寒热往来的症状。病位应当在半表半里，不适合用发汗或攻下的治法，所以给予黄芩汤，以和解半表半里的邪气。）此方于是成为治疗痢疾的祖方，（利，指泄泻。痢，指滞下。）后人加减化裁或更改名称。（刘完素的黄芩芍药汤、芍药汤，都是从此方演化而来，遂成为千秋万代治疗痢疾的祖方了。）再加生姜与半夏，（命名为黄芩加半夏生姜汤）治疗下利兼有呕吐此方能平复。（下利即专门治疗腹泻，不混杂风寒解表药物，这也是急当救里的意义。如果呕吐也同时加入止呕的药物，根据见证施治，古人通常不出此范围。倘若服药后原本的症状痊愈，随后出现其他症状，则仍然根据见证施治，可以推知如此。）也治疗胆咳呕吐苦汁，（胃气上逆则呕吐，胆汁热则味苦。）苦泄辛通的方法最为精妙。（酸苦泄热，辛甘和胃，胃气调和，胆热清除，咳嗽且呕吐苦味自然停止。）

Treats the aforementioned syndrome accompanied by vomiting; also treats Gallbladder Cough (Dan Ke), characterized by coughing and vomiting bitter fluid resembling bile juice.
To the original formula of Huangqin Tang (Scutellaria Decoction), add Banxia (Pinelliae Rhizoma) half sheng, and Shengjiang (Zingiberis Rhizoma Recens) three liang, with the remaining preparation method being the same.
Huangqin Tang uses Gancao (Glycyrrhizae Radix et Rhizoma) and Shaoyao (Paeoniae Radix Alba), cooked with Zao (Jujubae Fructus) for combined disease of Taiyang and Yangming presenting with diarrhea. (Note: Why are herbs from both the Taiyin and Shaoyang meridians not used for the combined disease of these two yang channels? Because combining bitter herbs drains the heat of Shaoyang, while the sour-sweet nature of Shaoyao and Zao harmonizes the Qi of Taiyin, clearing the interior-half so that the exterior-half resolves spontaneously. The method of harmonizing is not limited to one approach. Combined disease refers to having symptoms of Taiyang such as headache and stiffness of the head and neck, spine, alongside symptoms of Shaoyang such as deafness, hypochondriac pain, bitter taste in the mouth, and alternating chills and fever. The pathogen lies at the half-exterior and half-interior, making sweating and purging inappropriate; thus, Huangqin Tang is given to harmonize the pathogen at the half-exterior and half-interior.) This formula subsequently became the ancestral formula for treating Dysentery (Li). (Li refers to diarrhea; Li [dysentery] refers to tenesmus/stagnant discharge.) Later generations added ingredients or renamed it. (Liu Wansu's Huangqin Shaoyao Tang and Shaoyao Tang were both derived from this formula, becoming the ancestral formula for treating dysentery for all generations.) Adding further Shengjiang and Banxia (named Huangqin Jia Banxia Shengjiang Tang / Scutellaria Decoction plus Pinellia and Fresh Ginger) can calm diarrhea accompanied by vomiting. (Diarrhea treatment focuses specifically on relieving diarrhea without mixing in wind-cold exterior-resolving herbs, reflecting the principle of urgently saving the interior. If vomiting occurs, anti-emetic herbs are added concurrently; treating according to the manifested signs was the standard practice of the ancients. If the primary symptoms resolve after taking the medicine but other symptoms appear subsequently, treatment should still be adjusted according to the new manifestations, which can be inferred.) It also treats Gallbladder Cough with vomiting of bitter juice. (Stomach Qi rebelling upward causes vomiting; heat in the Gallbladder causes bitterness.) The method of bitter-draining and pungent-unblocking is most exquisite. (Sour and bitter drain heat; pungent and sweet harmonize the Stomach. When Stomach Qi is harmonized and Gallbladder heat is cleared, coughing and vomiting of bitter fluid cease naturally.)
(Liu Wansu, *Suwen Bingji Qiyi Baoming Ji*) Treats hot dysentery with abdominal pain and tenesmus, body fever, thick and sticky pus and blood, and a surging and rapid pulse.
