Ephedrae Herba (Mahuang, 麻黄) (2.5 liang, remove joints), Cimicifugae Rhizoma (Shengma, 升麻) (1.1 liang), Angelicae Sinensis Radix (Danggui, 当归) (1.1 liang), Anemarrhenae Rhizoma (Zhimu, 知母), Scutellariae Radix (Huangqin, 黄芩), Polygonati Rhioma (Weirui, 葳蕤) (each 18 zhu), Gypsum Fibrosum (Shigao, 石膏) (crushed, wrapped in cotton cloth), Atractylodis Macrocephalae Rhizoma (Baizhu, 白术), Zingiberis Rhizoma (Ganjiang, 干姜), Paeoniae Radix Alba (Shaoyao, 芍药), Asparagi Radix (Tianmendong, 天门冬) (remove heart), Cinnamomi Ramulus (Guizhi, 桂枝), Poria (Fuling, 茯苓), Glycyrrhizae Radix et Rhizoma (Gancao, 甘草) (honey-fried, each 6 zhu).
The above fourteen ingredients. Use one dou of water. First decoct Ephedrae Herba until it boils for the duration of two or three grains of rice falling. Remove the foam on the surface. Add the remaining herbs. Decoct to obtain three sheng of liquid. Remove the dregs. Divide into three warm doses. The interval between doses should be approximately the time it takes to cook three dou of rice. Administer completely. Recovery occurs with sweating.
Cheng Wuji's commentary cites the *Yufang Jing* saying: For severe heat qi, use cold medicines to resolve it. For extreme heat qi, use diaphoresis to disperse it. The sweet nature of Mahuang and Shengma is used to disperse floating heat. For those with deficient righteous qi, use acrid-moistening methods. The acrid nature of Danggui, Guizhi, and Ganjiang is used to dispel cold. For heat in the upper jiao, use bitter drugs to drain heat. The bitter nature of Zhimu and Huangqin cools the heart and removes heat. For those with insufficient body fluids, use sweet-moistening methods. The sweet nature of Fuling and Baizhu soothes the spleen and generates fluids. For lung dryness and qi heat, use sour astringents. Use sweet agents to moderate urgency. The sour nature of Shaoyao is used to constrain rebellious qi. The sweet nature of Weirui, Tianmendong, Shigao, and Gancao moistens the lung and removes heat.
Hu notes: The aforementioned formula by Zhang Zhongjing, being a complex mixture of cold and heat, has annotations by Cheng Shi that contain many errors. Moreover, this is a difficult-to-treat syndrome of Jueyin disease; how can physicians apply treatment?
Hu further notes: The aforementioned decoction consists of herbs acting on the Lung and Spleen, while also affecting the Liver. Mahuang and Shengma ascend the yang of the Lung and Spleen. Zhimu, Huangqin, Shigao, Weirui, and Tianmendong clear dryness-heat in the Lung. Since purgation has already been performed, body fluids are severely depleted. Additionally, expectoration of pus and blood indicates the Lung is even drier and hotter. Baizhu, Fuling, and honey-fried Gancao warm and tonify Spleen deficiency and primarily treat diarrhea. Profuse downward discharge leads to loss of yin; therefore, Shaoyao and Danggui are used to harmonize and tonify the yin of the middle and lower jiao. Both the Liver and Spleen benefit. Dried Ginger (Ganjiang) is used to warm the middle qi to counteract the cold nature of Zhimu, Huangqin, and Shigao. Cinnamon Twig (Guizhi) is used to harmonize Ying and Wei and assist in ascending yang. Taking the medicine completely to induce sweating does not mean using these herbs to forcibly induce perspiration; rather, it demonstrates that when Yin and Yang harmonize, slight sweating occurs, and symptoms such as cold extremities naturally resolve.
In Cold Damage after four or five days, if there is abdominal pain, and one feels gas moving downward toward the lower abdomen, this indicates an impending spontaneous diarrhea. (This clause describes the syndrome of Jueyin abdominal pain preceding spontaneous diarrhea. Four or five days into Cold Damage is the time when pathogenic factors transmit inward. Abdominal pain involves all three Yin meridians traversing the abdomen. If there is additionally gurgling gas moving down to the lower abdomen, this clearly indicates Jueyin meridian abdominal pain. Interior qi is deficient and encounters pathogenic heat, so it does not bind upward in the chest but moves downward into the intestines, intending to form a spontaneous diarrhea syndrome. According to this clause, Zhang Zhongjing provides no treatment method. My opinion is: if diarrhea has not yet occurred, Si Ni San is appropriate; if diarrhea has already occurred, Bai Tou Weng Tang is appropriate. In the *Bu Wang Lun*, Chang Qizhi suggests Si Ni Tang powder. I believe that using a decoction to dispel cold contradicts the cold-heat dynamics; why would it be mistakenly used?)
If Cold Damage originally involved cold-type diarrhea, and the physician repeatedly applies emesis and purgation, cold obstruction occurs, exacerbating vomiting and diarrhea. If food is vomited immediately upon entering the mouth, Gan Jiang Huang Lian Huang Qin Ren Shen Tang is indicated. (This clause discusses the complicated syndrome resulting from excessive emesis and purgation in Jueyin Cold Damage. "Originally involving cold diarrhea" refers to the patient having inherent stomach qi deficiency and cold with diarrhea. When Jueyin pathogenic factors bind in the chest causing fullness and irritability below the heart, emesis is indeed indicated; when there is prior heat followed by cold extremities, purgation is indicated. If the physician ignores the cold, heat, excess, and deficiency and applies emesis and purgation, since these medications are typically bitter-cold, cold obstruction arises from the mutual rejection of cold and heat, creating upper cold and lower heat. Consequently, the patient experiences exacerbated vomiting and diarrhea, meaning the condition worsens with vomiting above and diarrhea below. Vomiting food immediately upon ingestion describes the extremity of rebellious qi. Gan Jiang Huang Lian Huang Qin Ren Shen Tang is used to open the cold obstruction, clear heat in the middle and lower jiao, and simultaneously tonify interior deficiency.)
