太阳少阳并病。而反下之。成结胸。心下硬。下利不止。水浆不下。其人心烦。
太阳少阳并病。为邪气在半表半里也。而反下之。二经之邪。乘虚而入太阳。表邪
入里结于胸中为结胸。心下硬。少阳里邪。乘虚下于肠胃。遂利不止。若邪结阴分。则
饮食如故。而为脏结。此为阳邪内结。故水浆不下而心烦。
脉浮而紧。而复下之。紧反入里。则作痞。按之自濡。但气痞耳。
浮而紧。浮为伤阳。紧为伤阴。当发其汗而反下之。若浮入里。为阳邪入里。则作结

Banxia (Pinelliae Rhizoma, half sheng, washed; acrid and neutral) Huangqin (Scutellariae Radix; bitter and cold) Ganjiang (Zingiberis Rhizoma; acrid and hot) Renshen (Ginseng Radix et Rhizoma; above three each san liang; sweet and warm)
Huanglian (Coptidis Rhizoma; one liang; bitter and cold) Dazao (Jujubae Fructus; twelve pieces, split; warm and sweet) Gancao (Glycyrrhizae Radix et Rhizoma; san liang, honey-fried; sweet and neutral)
The above seven herbs. Use ten dou of water. Boil to obtain six sheng. Remove the dregs. Boil again. Obtain three sheng. Take one sheng warm. Three times daily.
Acrid substances enter the Lung and disperse qi. The acridity of Banxia disperses knotted qi. Bitter substances enter the Heart and drain heat. The bitterness of Huangqin and Huanglian drains the heat of pi syndrome (epigastric fullness and stuffiness).
The Spleen desires relaxation. In urgency, eat sweet substances to relax it. The sweetness of Renshen, Gancao, and Dazao relaxes it.
Taiyang and Shaoyang Bingbing (concurrent disease of Taiyang and Shaoyang channels), yet contrary to indications, purgation was used. This resulted in Jie Xiong (chest binding syndrome). The epigastrium is hard. Diarrhea continues incessantly. Food and drink cannot be taken. The patient is vexed.
Taiyang and Shaoyang Bingbing indicates pathogenic factors are at the half-exterior and half-interior. Yet contrary to indications, purgation was used. The pathogens of both channels entered the Taiyang channel by taking advantage of the deficiency. Exterior pathogens entered the interior and knotted in the chest, forming Jie Xiong, with hardness in the epigastrium. Interior pathogens of Shaoyang descended into the intestines and stomach by taking advantage of the deficiency, leading to incessant diarrhea. If pathogens knot in the Yin aspect, diet remains normal, forming Zang Jie (zang binding syndrome). This is Yang pathogens knotting internally, hence inability to take food/drink and mental vexation.
Pulse is floating and tight. Yet contrary to indications, purgation was used. The tightness reverses and enters the interior, forming Pi syndrome (stagnation syndrome). Palpation reveals softness; it is merely Qi stagnation.
Floating and tight: floating indicates injury to Yang, tight indicates injury to Yin. Sweating should have been induced, but purgation was used contrary to indications. If the floating (Yang pathogen) enters the interior, Yang pathogens entering the interior form Jie Xiong. If the floating does not enter the interior, but the tight (Yin pathogen) enters the interior, Yin pathogens entering the interior form Pi syndrome.
Taiyang Wind Strike syndrome, with diarrhea and vomiting/reversal. Only after the exterior syndrome resolves can attack (purgation) be used. The patient sweats. Episodes occur at fixed times. Headache. Epigastric pi and hardness/fullness. Pain radiating to the hypochondrium. Dry retching. Shortness of breath. Sweating. No aversion to cold. This indicates the exterior has resolved but the interior is not harmonized. Shizao Tang (Ten Date Decoction) is indicated.
Diarrhea and vomiting/reversal indicate the interior is affected by pathogens. Pathogens in the interior may be purged. However, one must wait for the exterior to resolve before attacking. The patient sweats. Episodes occur at fixed times. No aversion to cold indicates the exterior has resolved. Headache, epigastric pi, hardness/fullness, pain radiating to the hypochondrium, dry retching, and shortness of breath indicate internal accumulation of pathogenic heat and latent fluid retention. This means the interior is not harmonized. Administer Shizao Tang to purge heat and drive out fluid retention.
