Ganjiang (Radix Zingiberis Preparata, 1 liang) Fuzi (Rhizoma Aconiti Lateralis Preparatus, 1 piece, used raw, peeled, broken into eight pieces)
The above two ingredients. With three sheng of water, boil to obtain one sheng. Remove the dregs and take in one dose.
Cheng Wuji's commentary cites the *Neijing*: "When cold pathogen prevails excessively, pacify it with acrid-hot substances." Since deficiency-cold is too severe, an acrid-hot formula is used to overcome it.
Hu notes: In the above formula, Ganjiang stabilizes the middle jiao and eliminates interior cold; Fuzi warms the meridians and disperses exterior cold. Once the yin pathogen recedes, yang qi naturally recovers.
After sweating therapy, if the disease does not resolve but instead aversion to cold occurs, this is due to deficiency. Shaoyao Gancao Fuzi Tang (Peony and Licorice with Aconite Decoction) is the primary treatment. (In Taiyang syndrome, sweating therapy should resolve the disease. Even if unresolved, aversion to cold should not occur. If a Zhonghan [Cold Damage] case is forcibly sweated, the disease will not resolve and aversion to cold will inevitably follow. Sweating depletes Ying blood, while aversion to cold indicates Wei qi deficiency. Cheng Wuji notes: "Both Ying and Wei are deficient." Shaoyao Gancao Fuzi Tang is administered to tonify Ying and Wei.)
Shaoyao (Radix Paeoniae Rubra) Gancao (Radix Glycyrrhizae Preparata, roasted, each 3 liang) Fuzi (Rhizoma Aconiti Lateralis Preparatus, 1 piece, processed, peeled, broken into eight pieces)
The above three ingredients. With five sheng of water, boil to obtain one sheng and five he. Remove the dregs. Divide into two warm doses.
Cheng Wuji notes: The sourness of Shaoyao astringes body fluids and nourishes Ying; the acrid-hot nature of Fuzi secures Yang qi and supplements Wei; the sweetness of Gancao harmonizes acrid and sour flavors and stabilizes healthy Qi. Hu notes that the original prescription contains the phrase "suspected not to be Zhang Zhongjing's intention." Perhaps Wang Shuhe, when compiling this formula, interpreted the previous clause as Taiyang syndrome where sweating failed to resolve the disease and aversion to cold persisted, indicating residual exterior pathogen still requiring sweating. Thus, he suspected this formula was not Zhang Zhongjing's intent and seemed unusable. Therefore, *Neitai Fangyi* also states: If there is no massive sweating, yet aversion to cold recurs, with a deep and faint pulse and no heat signs, it must not be taken. Understanding this, the application of the aforementioned formulas can be free of doubt.
After sweating or purging therapy, if the disease remains unresolved and restlessness (fan zao) occurs, Fuling Sini Tang (Poria and Reverse Cold Decoction) is the primary treatment. (In Taiyang syndrome, after sweating and purging, restlessness should cease and the disease resolves. However, in Zhonghan cases, forced sweating causes exterior laxity and loss of Yang; subsequent purging causes interior deficiency and loss of Yin. Wei qi loses its guard, Ying blood becomes empty internally, pathogen remains unresolved, generating restlessness. This is deficiency-induced restlessness, a manifestation of false heat. Only warming and tonifying are appropriate; dispersing pathogen is contraindicated. Hence, Fuling Sini Tang is used.)
