Treats retained fluid (accumulation of pathological fluids) caused by Shanghan (Cold Damage).
Douchi (Fermented Soybean, 1 sheng) Badou (Crotonis Fructus, de-oiled, 300 seeds; now use 200 seeds) Xingren (Prunus Armeniacae Semen, 60 seeds) Huangqin (Scutellariae Radix) Huanglian (Coptidis Rhizoma) Dahuang (Rhei Radix et Rhizoma) Mahuang (Ephedrae Herba, each 4 liang) Mangxiao (Natrii Sulfas) Gansui (Kansui Radix, each 3 liang)
The above nine ingredients. Grind into powder. Mix with honey to form pills. Size like soybeans. Take two pills. If defecation does not occur, increase the dose.
Hu notes: The above formula is similar to the previous one. However, its purgative force is greater, and its diaphoretic force is less. Nevertheless, it is too rapid and fierce. It should be used only after assessing the patient's deficiency or excess.
Hu summarizes: Although the above two formulas are used to treat incomplete resolution of Taiyang exterior pathogenic factors, they are actually medicines for treating Yangming Fu-organ excess (excess heat and accumulation in the stomach and intestines).
Chen Yanzhi treats Shanghan. If the condition is not resolved after one or two days, there is Baiwei San in the *Duanju* text.
(The *Qianjin Fang* also collects this powder.)
Baiwei (Cynanchum Atrati Radix, 2 liang) Mahuang (Ephedrae Herba, 7 fen, remove joints) Xingren (Prunus Armeniacae Semen, remove skin and tips, stir-fry) Beimu (Fritillariae Bulbus, each 3 fen)
The above four ingredients. Pound into a powder. Administer with wine, one fangcun bi (a measure of volume). Cover thickly and lie down. Recovery occurs when sweating appears.
Hu notes: Chen states above that it treats Shanghan. If the condition is not resolved after one or two days. According to the *Neijing*: On the first day of Shanghan, the Juyang (Taiyang) channel receives the pathogen. On the second day, the Yangming channel receives the pathogen. Therefore, the above formula should be considered medicine for the Taiyang and Yangming channels. It is a modified version of Zhongjing's Mahuang Tang and Gegen Tang. Furthermore, for the Hand-Taiyin Lung channel, where wind is excessive and heat is congested, it should also be used with discretion. Additionally, regarding Baiwei, Li Shizhen’s *Bencao Gangmu* states that it was widely used in ancient times but rarely known in later generations. Its root resembles Niuxi (Achyranthis Bidentatae Radix) but is shorter. Its nature is bitter and cold, making it a medicine for the Yangming channel. The *Shennong Bencao Jing* indicates it treats sudden wind-stroke, body heat, limb fullness, sudden inability to recognize people, as well as warm malaria with alternating chills and fever occurring at specific times. Thus, the *Huo Ren Shu* uses it in Weirui Tang to treat wind-warmth after sweating, characterized by burning body heat and somnolence. From this, we know that Baiwei uses the root, which is non-toxic in the Materia Medica yet beneficial to humans. Why do common physicians fail to know how to use it?
It also treats Dongwen (Winter-Warmth), and Shanghan contracted from windstroke in spring. Symptoms include fever, dizziness and headache, dry throat and pharynx, stiff tongue, pain inside the chest, chest and heart stuffiness, knotting and fullness, stiffness of the waist and back. There is Weirui Tang in the *Duanju*.
