半夏（半升洗） 黄芩 干姜 甘草（炙） 人参（以上各三两） 黄连（一两） 大枣（十二枚擘）
上七味。以水一斗。煮取六升。去滓。再煮取三升。温服一升。日三服。
成注云。辛入肺而散气。半夏干姜之辛。以散结气。苦入心而泄热。黄连黄芩之苦。以泄痞热。脾欲缓。急食甘
以缓之。人参甘草大枣之甘。以缓之。愚以结胸挟实。痞气挟虚。故用人参甘草大枣之甘缓以补之也。
内台方议曰。病在半表半里。本属柴胡汤。反以他药下之。虚其肠胃。邪无所归。故结于心下。重者成结胸。心下
满而硬痛也。轻者为痞。满而不痛也。若此痞结不散。故以黄连为君。苦入心以泄之。黄芩为臣。降阳而升阴也。半夏
干姜之辛温为使。辛能散其结也。人参甘草大枣之甘。以缓其中。而益其肠胃之不足。使气得平。上下升降。阴阳得和。
其邪之留结者。散而已矣。经曰。辛入肺而散气。苦入心而泄热。甘以缓之。三者是矣。
太阳与少阳合病。自下利者。与黄芩汤。若呕者。黄芩加半夏生姜汤主之。（此条虽系太少合病。实则少阳之证居多。
故从少阳篇例。成注云太阳阳明合病。自下利为在表。宜发汗阳明少阳合病。自下利。为在里宜下之。此太阳少阳合病。
自下利。为在半表半里。非汗下所宜。故与黄芩汤。以和解半表半里之邪。呕者。胃气逆也。加半夏生姜以散逆气。愚
意以此必是胃中有停饮而作呕。故宜加也。）
半夏（半升，洗净） 黄芩 干姜 甘草（炙烤） 人参（以上各三两） 黄连（一两） 大枣（十二枚，掰开）
以上七味药。用水一斗。煮取六升药液。滤去药渣。再次煎煮取三升药液。每次温服一升。每日服用三次。
成无己注释说：辛味入肺而能发散气机。半夏、干姜的辛味，用来消散结聚之气。苦味入心而能泄热。黄连、黄芩的苦味，用来泄除痞塞之热。脾脏喜好缓和，急需食用甘味食物来缓和它。人参、甘草、大枣的甘味，用来缓和脾急。我认为结胸证夹有实邪，痞证夹有虚邪，所以用人参、甘草、大枣的甘缓之性来补益它。
《内台方议》议论说：病位在半表半里，本应属于柴胡汤证。反而用其他药物攻下，导致肠胃虚弱，邪气无处归依，所以结聚在心下部位。严重的形成结胸，表现为心下满而且硬痛。轻的称为痞证，表现为满而不痛。如果这种痞结不散，所以用黄连为君药，苦味入心以泄热。黄芩为臣药，降阳气而升阴气。半夏、干姜的辛温之性为使药，辛味能散其结聚。人参、甘草、大枣的甘味，用来缓和中焦，并补益肠胃的不足，使气机平和，上下升降正常，阴阳调和，那些留滞结聚的邪气也就消散了。经文说：辛味入肺而散气，苦味入心而泄热，甘味以缓和之。这三种道理都符合了。
太阳经与少阳经同时发病，出现自发性腹泻的，给予黄芩汤治疗。如果有呕吐症状的，主治方剂为黄芩加半夏生姜汤。（这一条虽然涉及太阳和少阳合病，但实际上少阳证的成分居多。所以遵循少阳篇的体例。成无己注释说：太阳阳明合病，自发性腹泻，病在表，适宜发汗；阳明少阳合病，自发性腹泻，病在里，适宜攻下。这里是太阳少阳合病，自发性腹泻，病在半表半里，不是发汗或攻下的适应症。所以给予黄芩汤，以和解半表半里的邪气。呕吐，是胃气上逆的表现。加入半夏、生姜以散除上逆之气。我的意思是这必定是胃中有停积的水饮导致呕吐，所以适宜加入。）
Banxia (Half Sheng, washed) Huangqin Ganjiang Gancao (roasted) Renshen (each of the above three liang) Huanglian (one liang) Dazao (twelve pieces, split open)
The above seven ingredients. Use one dou of water. Boil to obtain six sheng of liquid. Remove the dregs. Boil again to obtain three sheng of liquid. Take one sheng warm each time. Administer three times a day.
Cheng Wuji's commentary states: Pungent flavors enter the Lung and disperse Qi. The pungency of Banxia and Ganjiang disperses stagnant Qi. Bitter flavors enter the Heart and drain heat. The bitterness of Huanglian and Huangqin drains the heat of obstruction (Pi). The Spleen desires relaxation; urgently consume sweet flavors to relax it. The sweetness of Renshen, Gancao, and Dazao relaxes it. I believe that Jie Xiong (chest binding) involves excess pathogens, while Pi syndrome involves deficiency pathogens; therefore, the sweet and relaxing nature of Renshen, Gancao, and Dazao is used to tonify them.
Discussion in Neitai Fangyi states: The disease is located at half-exterior and half-interior, originally belonging to Chaihu Tang (Bupleurum Decoction). Instead, other drugs were used to purge, weakening the Stomach and Intestines, leaving the pathogen with no place to go, thus knotting at the epigastrium. Severe cases become Jie Xiong (chest binding), characterized by fullness, hardness, and pain in the epigastrium. Mild cases are called Pi (obstruction/fullness), characterized by fullness without pain. If this Pi knot does not dissipate, Huanglian is used as the Sovereign herb; bitter enters the Heart to drain it. Huangqin is used as the Minister herb, descending Yang and ascending Yin. The pungent-warm nature of Banxia and Ganjiang serves as the Envoy; pungency can scatter the knot. The sweetness of Renshen, Gancao, and Dazao relaxes the Middle Jiao and benefits the insufficiency of the Stomach and Intestines, allowing Qi to be balanced, upper and lower movements to normalize, and Yin and Yang to harmonize, so that the lingering and knotted pathogens are scattered. The Canon says: Pungent enters the Lung and disperses Qi; bitter enters the Heart and drains heat; sweet relaxes. These three principles apply here.
Taiyang (Greater Yang) and Shaoyang (Lesser Yang) simultaneous disease presenting with spontaneous diarrhea is treated with Huangqin Tang (Scutellaria Decoction). If vomiting occurs, Huangqin Jia Banxia Shengjiang Tang (Scutellaria Decoction plus Pinellia and Fresh Ginger Decoction) is the primary treatment. (Although this clause relates to Taiyang-Shaoyang simultaneous disease, actually the Shaoyang syndrome predominates. Therefore, it follows the examples of the Shaoyang chapter. Cheng's commentary states: Taiyang-Yangming simultaneous disease with spontaneous diarrhea indicates the pathogen is in the exterior, suitable for sweating; Yangming-Shaoyang simultaneous disease with spontaneous diarrhea indicates the pathogen is in the interior, suitable for purging. This Taiyang-Shaoyang simultaneous disease with spontaneous diarrhea indicates the pathogen is at half-exterior and half-interior, making sweating and purging inappropriate. Thus, Huangqin Tang is given to harmonize the pathogens at half-exterior and half-interior. Vomiting is due to rebellious Stomach Qi. Banxia and Shengjiang are added to scatter the rebellious Qi. My opinion is that there must be retained fluid in the Stomach causing vomiting, hence the addition is appropriate.)
