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。）
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.)
