葛根（半斤） 乌梅（十四枚） 葱白（一握） 豉（一升绵裹）
上四味。切。以水九升。煮取三升。分为三服。初一服。便浓覆取汗。汗出粉傅之。（崔氏取名葛根汤。方中无乌梅。
琥按上主疗云。伤寒一日至三日。是初起即入阳明。至三日为应汗之时。故以葛根葱白之甘辛。以解肌发汗。豆豉之苦
甘。以泄热除烦。乃阳明经发表之神剂。但方中乌梅一味。味酸收敛为不可用也。）
又石膏汤。疗伤寒病已八九日。三焦热。其脉滑数。昏愦。身体壮热。沉重拘挛。或时呼呻。而已攻内。体犹沉重
拘挛由表未解。今直用解毒汤。则挛急不瘥。直用汗药。则毒因加剧。而方无表里。疗者意思以三黄汤以救其内。有所
增加以解其外。故名石膏汤方。
石膏 黄连 黄柏 黄芩（各二两） 香豉（一升绵裹） 栀子（十枚擘） 麻黄（三两去节）
上七味。切。以水一斗。煮取三升。分为三服。一日并服。出汗。初服一剂。小汗其后。更合一剂。分两日服。常
令微汗出。拘挛烦愦即瘥。得数行利心开。令语毒折也。
琥按上方。即三黄石膏汤也。虽云疗三焦热。实则阳明经府齐热。但表邪尚在。里未结实。故不可下。此方为清解
最重之剂。愚意以方中栀子太少。麻黄太多。石膏宜倍用。其效更神。
Ge Gen (Radix Puerariae, half jin) Wu Mei (Fructus Mume, fourteen pieces) Cong Bai (Bulbus Allii Cepae, one handful) Chi (Folium Sojae Preparatum, one sheng, wrapped in silk)
The above four herbs. Cut into pieces. Boil with nine sheng of water until three sheng remain. Divide into three doses. After the first dose, immediately cover thickly to induce sweating. Apply powder to the body after sweating. (Cui Shi named this formula Gegen Tang [Pueraria Decoction], but this formula does not contain Wu Mei.)
Wang Hu notes: The aforementioned indications state that Shanghan (Cold Damage) from day one to day three indicates that the pathogen has entered the Yangming channel upon onset. By the third day, it is time for diaphoresis. Therefore, the sweet and acrid properties of Ge Gen and Cong Bai are used to release the muscle layer and induce sweating; the bitter and sweet properties of Chi are used to drain heat and relieve irritability. This is a divine agent for releasing the exterior in the Yangming channel. However, Wu Mei in the formula has an sour and astringent nature, which prevents its use.)
Additionally, there is Shigao Tang [Gypsum Decoction], which treats Shanghan disease persisting for eight or nine days, with heat in the Sanjiao (Triple Burner), slippery and rapid pulse, confusion and lethargy, high fever, heaviness, and stiffness or spasms. Sometimes accompanied by shouting or groaning. If internal purging is applied directly, the body remains heavy and stiff because the exterior pathogen has not been resolved. If detoxifying agents are used directly, the spasms will not improve; if diaphoretic drugs are used directly, the toxin will worsen due to sweating. This formula lacks a clear focus on either interior or exterior. The practitioner's intent was to use Sanhuang Tang [Three Yellows Decoction] to rescue the interior heat, adding ingredients to resolve the exterior, hence named Shigao Tang.
Shi Gao (Gypsum Fibrosum) Huang Lian (Rhizoma Coptidis) Huang Bo (Cortex Phellodendri) Huang Qin (Radix Scutellariae) (each two liang) Xiang Chi (Folium Sojae Preparatum, one sheng, wrapped in silk) Zhi Zi (Fructus Gardeniae, ten pieces, broken) Ma Huang (Herba Ephedrae, three liang, nodes removed)
The above seven herbs. Cut into pieces. Boil with one dou of water until three sheng remain. Divide into three doses. Take all within one day. Induce sweating. After the initial dose, slight sweating occurs. Then combine the remaining dosage to be taken over two days. Maintain a state of slight sweating continuously. Stiffness, spasms, and irritability will then heal. Several episodes of diarrhea lead to mental clarity, indicating the reduction and dispersion of toxins.
Wang Hu notes: The above formula is essentially Sanhuang Shigao Tang [Three Yellows and Gypsum Decoction]. Although it claims to treat Sanjiao heat, it actually addresses simultaneous heat in the Yangming channel and fu organs. However, since exterior pathogens remain and interior excess is not yet solidified, purgation is contraindicated. This formula is the heaviest agent for clearing heat and resolving the exterior. In my opinion, the amount of Zhi Zi in the formula is too little, and Ma Huang is too much. Shi Gao should be doubled for more miraculous efficacy.
