Shaoyin disease, occurring two to three days after onset, presenting with dry mouth and throat, is suitable for purgation treatment, using Dachengqi Tang (Major Order the Qi Decoction). Shaoyin disease, presenting with spontaneous diarrhea of pure green watery stool, pain in the epigastrium, and accompanied by dry mouth and throat, is suitable for Dachengqi Tang (Major Order the Qi Decoction). (The discussion is found under "Diarrhea".) In Cold Damage disease, without significant fever on the exterior, but with dry mouth and thirst, and aversion to cold in the back, Baihu Jia Renshen Tang (White Tiger Decoction plus Ginseng) should be used. Yangming disease, presenting with fever and sweating, no aversion to cold but rather aversion to heat, if accompanied by dry mouth and tongue, Baihu Jianshen Tang (White Tiger Decoction plus Ginseng) should be used. (The formula discussion is found under "Thirst and Exterior Resolution" section.)
Taiyang disease, following purgation therapy, presents with constipation, tidal fever at dusk (Ribang Chaore), fullness and pain in the epigastrium, and dry mouth with thirst on the tongue; Datianxiong Tang (Major Trap the Chest Decoction) is indicated.
Yangming disease, presenting with dry mouth, where the patient desires to rinse water in the mouth but does not swallow it, will inevitably develop epistaxis (nosebleed). (Haizang stated: If the presentation involves desiring to rinse but not swallowing, chest fullness, and tenderness upon pressure in the epigastrium, Taoren Chengqi Tang (Peach Kernel Order the Qi Decoction) is the primary formula.)
The patient appears silent and sleepy, yet cannot close their eyes, is restless in daily activities, has hoarseness, or dry throat; this should be treated as Huhuo Disease (Fox-Secretion Disease, often corresponding to Behçet's disease). Dry throat contraindicates diaphoresis (sweating method).
In Shaoyin disease, two to three days after onset, if sore throat occurs, Gancao Tang (Licorice Decoction) may be given; if not cured, Jiegeng Tang (Platycodon Decoction) should be used.
Gancao Tang uses two liang of Gancao (Radix Glycyrrhizae Preparata), chopped, taken four qian per dose, decocted in water, strained, and taken warm, three times a day.
Jiegeng Tang uses two liang of Gancao (Radix Glycyrrhizae Preparata) and one liang of Jiegeng (Radix Platycodi), chopped, taken five qian per dose, decocted in water and taken warm.
For Shaoyin disease with pain in the throat, Banxia San Ji Tang (Pinellia Powder and Decoction) is the main treatment.
Banxia (Prepared) Guizhi (Ramulus Cinnamomi) Gancao (Roasted). Each in equal parts.
Chop the above ingredients, decoct in water, and take orally in small amounts repeatedly. Alternatively, prepare as a powder, mix with plain water, and take one cunbi (a measure roughly equivalent to a spoonful) per dose; this is also effective, taken three times a day. (Zhang Zhongjing's method was to prepare as a powder mixed with water, not to chop and decoct.)
[Cheng Wuji's Commentary] Gancao Tang (Licorice Decoction) treats sore throat caused by exogenous heat invading Shaoyin. Jiegeng Tang (Platycodon Decoction) treats sore throat caused by the struggle between cold and heat in Shaoyin. Banxia San Ji Tang (Pinellia Powder and Decoction) treats sore throat caused by exogenous cold in Shaoyin.
In Shaoyin disease, if sores form in the throat, preventing speech and voice production, Kujiu Tang (Bitter Wine Decoction) is the main treatment.
Banxia (Prepared, fourteen pieces) Ji Zi (one egg, remove yolk, place Banxia and Kujiu [vinegar] into the eggshell).
Place the two ingredients together, putting Banxia into the shell with Kujiu. Place the eggshell in a knife handle or similar container, set over fire, boil three times, strain, and hold in the mouth to swallow slowly in small amounts. If not cured, prepare three more doses.
A tight pulse usually indicates absence of sweating; if sweating occurs instead, it signifies collapse of Yang (Wangyang). This belongs to Shaoyin disease; according to the law, it should present with sore throat accompanied by vomiting and diarrhea. (The discussion is found under "Vomiting and Diarrhea".) The Master said: Bingfuqi (Dormant Qi disease) requires intuitive observation. Within the current month, if dormant qi is suspected, and if there is a history of dormant qi, pulse diagnosis is necessary. If the pulse is weak, the patient should feel throat pain resembling Cold Damage, rather than Hou Bi (throat obstruction). The patient states: "Indeed, there is severe throat pain," although now they also desire diarrhea. (See later "Huo Ren" continuation methods).
Sore throat accompanied by diarrhea and chest fullness is treated with Zhufu Tang (Swine Skin Decoction). Cold limbs with red face are treated with Tongmai Sini Tang (Pulse-Reviving Four Reversals Decoction). Post-purgation recurrence of cold limbs with absent lower limb pulses is treated with Mahuang Shengma Tang (Ephedra and Ma Huang Shen Decoction). (All found under "Diarrhea".)
Yang Du (Yang Toxin) causing sore throat, with a red face and mottled rash like brocade patterns, expectoration of pus and blood, is treatable on the fifth day but untreatable on the seventh day. Shengma Biejia Tang (Cimicifuga and Turtle Shell Decoction) is indicated. (The "Huo Ren" book states: Yang Du is treated with Shengma Tang. The discussion is found under "Yang Du" section.)
Yin Du (Yin Toxin) causing sore throat, with blue-green complexion and body pain as if beaten by a club, is treatable on the fifth day but untreatable on the seventh day. Shengma Biejia Tang minus Xionghuang (Realgar) and Shujiao (Sichuan Pepper) is used. (The "Huo Ren" book states: Yin Du is treated with Gancao Tang. The discussion is found under "Yin Du" section.)
Taiyang disease, following purgation, if the pulse becomes tight, sore throat will inevitably occur. (The discussion is found under "General Principles".) Yangming disease, with dizziness and cough, will inevitably cause sore throat. If there is no cough, there will be no sore throat.
If cold limbs precede fever, diarrhea will stop spontaneously. If it stops but sweating ensues, the throat will become obstructed (Bi). If fever occurs without sweating, diarrhea will stop spontaneously. If it does not stop, pus and blood will appear in the stool, and the throat will not become obstructed. (The discussion is found under "Diarrhea".)
Throat obstruction contraindicates diaphoresis; diaphoresis will lead to hematemesis (vomiting blood), near-death of Qi, cold limbs, desire to curl up, and inability to self-warm. Throat obstruction contraindicates purgation; purgation will lead to upper deficiency and lower excess, inability to ingest food and drink, desire to curl up when lying down, bodily stiffness, dizziness, and diarrhea dozens of times a day.
