(From *Tai Ping Hui Min He Ji Ju Fang*)
Treats seasonal epidemics, simultaneous contraction of wind-cold, presenting with headache and fever, aversion to cold and absence of sweating, coughing, nasal congestion, and heavy voice. ("Seasonal qi" refers to contracting the abnormal qi of the four seasons; "epidemic" refers to disasters spreading through the population, infecting entire households similarly. Headache, fever, aversion to cold, and absence of sweating indicate pathogenic factors at the exterior level; coughing, nasal congestion...)
Ephedrae Herba (Mahuang), Puerariae Radix (Gegen), Cimicifugae Rhizoma (Shengma), Chuanxiong Rhizome (Chuanxiong), Angelicae Dahuricae Radix (Baizhi), Perillae Folium (Zisu), Glycyrrhizae Radix et Rhizoma (Gancao), Citri Reticulatae Pericarpium (Chenpi), Cyperi Rhizoma (Xiangfu), and Paeoniae Radix Rubra (Chishao), in equal proportions. Decoct with slices of fresh ginger (Shengjiang) and white parts of scallion (Congbai).
This is a general formula for external contractions affecting the Yang meridians. Wu Hegao stated: In ancient times, treating wind-cold required distinguishing symptoms according to the Six Meridians (Liu Jing) for medication. However, there are cases where fever, headache, aversion to cold, and nasal congestion occur without distinct manifestations of the Six Meridians patterns. (Wu Ang's note: The aforementioned conditions are also distinguishable as Yang patterns.) In such cases, one generally employs herbs that release the exterior and promote the smooth flow of Qi. In this formula, Chuanxiong, Mahuang, Shengma, Gegen, Baizhi, Zisu, Chenpi, and Xiangxiang are all acrid, aromatic, and Qi-promoting substances; thus, they can resolve the Qi stagnation caused by common colds (the various herbs disperse exterior pathogens, while Chenpi and Xiangfu guide interior Qi); furthermore, Shaoyao is added to harmonize Yin during diaphoresis, and Gancao is added to harmonize Yang within the dispersing and promoting group (Wu Shou stated: This decoction uses Shengma and Gegen to resolve and benefit Yangming epidemic seasonal qi; it is not a herb for true Taiyang Shanghan. If it were Taiyang Shanghan...)
(From Zhang Yuansu / Hai Zang)
Treats internal injury from consuming frozen/cold drinks combined with external contraction of cold pathogen resulting in absence of sweating. (Internal injury from cold drinks causes cold-dampness to stagnate in the Middle Jiao. The Classic states: Cold food entering the stomach causes Lung cold; Lung cold leads to the combination of internal and external pathogens. Thus, Shanghan can also arise from internal causes, not solely from external wind-cold. Cold nature congeals blood, hence the absence of sweating.) It also treats Gang Jing (Stiff Spasm), pure Taiyang Wind Strike patterns (Shanghan does not cause spasm; only when Wind Strike precedes Shanghan, or Wind Strike precedes Dampness, or after excessive sweating in Taiyang disease, or in Dampness patients who have undergone excessive... ) in cases with sweating.
Regarding Yang...
Atractylodis Rhizoma (Cangzhu, processed), Saposhnikoviae Radix (Fangfeng, 2 liang), Glycyrrhizae Radix et Rhizoma (Gancao, 1 liang, honey-fried). Decoct with fresh ginger (Shengjiang) and white parts of scallion (Congbai). If presenting with Taiyang syndrome symptoms of fever, aversion to cold, and floating pulse (Mai Fu)...
Add Angelicae Sinensis Radix (Danggui) for women.
This acts on the Foot-Taiyang Bladder Meridian. Fangfeng is acrid and warm, ascending and floating, dispelling wind and overcoming dampness, serving as the chief herb for the Taiyang meridian; Cangzhu is sweet, warm, and pungent with strong aroma, dispersing cold and inducing sweating, expelling evil and raising Yang (can raise the Yang Qi of the Stomach); Gancao is added to provide moderation within the dispersing action. (Note: Shen Shu San and Bai Zhu Tang were created by Hai Zang to substitute for Guizhi Tang and Mahuang Tang. Yu Jiayan stated: This is Hai Zang's masterpiece, likely intending to prevent unskilled practitioners from harming people with the heat of Mahuang and Guizhi. Changming...)
Removing Cangzhu from this formula and adding two liang of Atractylodis Macrocephalae Rhizoma (Baizhu), three slices of ginger, and omitting scallion, it is named Bai Zhu Tang. Hai Zang: Treats the aforementioned conditions with sweating (The therapeutic actions of the two Atractylodes species are slightly...)
