内经曰。寒淫所胜。平以辛热。虚寒大甚。是以辛热剂胜之也。
王海藏云。服姜附汤有二法。当热服。手少阴心也。水包火。热服以接心火。身表
寒盛。外火少也。寒从外生。热从内消。譬如冻死。寒在外也。一法当寒服。足少阴肾也。
寒邪入水。冷服以类肾水。身表微热。内水多也。热从外生。寒从内消。譬如饮冷。寒

发汗后。身疼痛。脉沉迟者。桂枝加芍药生姜各一两。人参三两。新加汤主之。
汗后身疼痛。邪气未尽也。脉沉迟。荣血不足也。经曰。其脉沉者。荣气微也。又曰。
迟者荣气不足。血少故也。与桂枝汤。以解未尽之邪。加芍药、生姜、人参。以益不
足之血。
张兼善云。或谓经言表邪盛。脉浮而紧。法当身疼痛。宜以汗解之。况身疼皆系表
邪未尽。此又加人参、芍药、生姜、以益血。何也。余曰。表邪盛则身疼。血虚则身亦

Dried Ginger and Aconite Decoction Formula (Ganjiang Fuzi Tang)
Dried Ginger (one tael, pungent and hot in nature) Raw Aconite Root (one piece, used raw, skin removed, broken into eight pieces, pungent and hot in nature)
The above two ingredients. With three sheng of water. Boil to obtain one sheng of decoction. Remove the dregs, take in one dose.
The *Neijing* states: When cold pathogen prevails excessively, use pungent and hot substances to level it. When deficiency-cold is extremely severe, therefore pungent and hot agents are used to overcome it.
Wang Haicang said: There are two methods for taking Jiangfu Tang. It should be taken hot. This relates to the Hand-Shaoyin Heart meridian. Water envelops fire; taking it hot connects with Heart Fire. The body surface has excessive cold, external fire is scant. Cold arises from outside, heat dissipates from inside. Like freezing to death, cold is on the outside. Another method is to take it cold. This relates to the Foot-Shaoyin Kidney meridian. Cold pathogen enters water; taking it cold mimics Kidney Water. The body surface has slight heat, internal water is abundant. Heat arises from outside, cold dissipates from inside. Like drinking cold liquids, cold is on the inside.
After sweating therapy, if there is body pain and a deep, slow pulse, Xinjia Tang (Newly Added Decoction), composed of Guizhi Tang (Cinnamon Twig Decoction) with additional one tael each of Shaoyao (Peony Root) and Shengjiang (Fresh Ginger), and three taels of Renshen (Ginseng Radix et Rhizoma), is the primary treatment.
Body pain after sweating indicates that pathogenic factors are not yet exhausted. A deep, slow pulse indicates insufficiency of Ying Blood (Nutritive Blood). The classics state: "A deep pulse indicates weak Ying Qi." Also: "A slow pulse indicates insufficient Ying Qi, due to blood deficiency." Administer Guizhi Tang (Cinnamon Twig Decoction) to resolve the remaining pathogens; add Shaoyao (Peony Root), Shengjiang (Fresh Ginger), and Renshen (Ginseng Radix et Rhizoma) to replenish the deficient blood.
Zhang Jianshan said: Some ask that the classics state when exterior pathogens are abundant, the pulse is floating and tight, and the method dictates body pain, suitable for resolution via sweating. Moreover, since body pain is associated with unexhausted exterior pathogens, why add Renshen (Ginseng Radix et Rhizoma), Shaoyao (Peony Root), and Shengjiang (Fresh Ginger) to nourish blood? I reply: Abundant exterior pathogens cause body pain; blood deficiency also causes body pain. A floating, tight pulse indicates pathogen abundance. A deep, faint pulse indicates blood deficiency. For abundance, reducing it brings peace; for deficiency, tonifying it brings recovery.
After sweating therapy, do not administer Guizhi Tang (Cinnamon Twig Decoction) again. If there is sweating and wheezing without significant heat, Mahuang Xingren Gancao Shigao Tang (Ephedra, Apricot Seed, Licorice, and Gypsum Decoction) may be administered as the primary treatment.
Sweating with wheezing and no significant heat in the body indicates that the lingering pathogen is confined to the Upper Jiao Lung organ. Therefore, Mahuang (Ephedrae Herba) and Xingren (Armeniacae Semen Amarum) are used to disperse pathogens in the chest, while Gancao (Glycyrrhizae Radix et Rhizoma) and Shigao (Gypsum Fibrosum) assist the function of the Metal element (Lung).
Wheezing after sweating should be treated with Guizhi Jia Houpo Xingren Tang (Guizhi Tang Plus Magnolia Bark and Apricot Seed Decoction). Sweating resolves the wheezing. Now, sweating with wheezing indicates severe pathogenic congestion; Guizhi Tang (Cinnamon Twig Decoction) cannot disperse it, so it must not be used again. Sweating with wheezing and significant heat indicates excessive internal heat qi. Sweating with wheezing and no significant heat indicates that exterior pathogens are certainly severe. Administer Mahuang Xingren Gancao Shigao Tang (Ephedra, Apricot Seed, Licorice, and Gypsum Decoction) to disperse the pathogens.
