In the spring of Jingkang Year 2, a severe epidemic broke out in the capital. A mysterious person inscribed a prescription on the wall of a study room. For anyone suffering from swelling due to the epidemic, taking this formula proved universally effective. The formula consisted of two he of black beans (Stir-fried until fragrant and cooked) and two cun of licorice root (Glycyrrhizae Radix et Rhizoma, roasted until yellow). Added with two zhan of water, it was decocted until the volume reduced by half, and taken in small sips occasionally.
In April of Taihe Year 2, many people suffered from epidemics. Initially, they felt aversion to cold, high fever, and body heaviness. Subsequently, the condition spread to severe swelling of the head and face, inability to open the eyes, upward panting, throat obstruction, dry tongue, and dry mouth. This was commonly known as "Big Head Cold" (Datu Shanghan). Various mixed medications failed to cure it, and the condition gradually worsened to a critical state. Li Dongyuan stated: The upper half of the body corresponds to the Qi of Heaven. When pathogenic heat lodges between the Heart and Lungs, it attacks upward to the head and face, causing swelling. It is necessary to use the following herbs, grind them into fine powder, take half mixed with water decoction occasionally, and take the other half as honey pills for buccal administration. Many were cured. People at that time called it an immortal prescription, claiming it was formulated by celestial beings.
Scutellariae Radix (Huangqin, 黄芩): Half liang, stir-fried with wine.
Coptidis Rhizoma (Huanglian, 黄连): Five qian, stir-fried with wine.
Ginseng Radix (Renshen, 人参): Three qian.
Citri Reticulatae Pericarpium (Chenpi, 陈皮): White pith removed, two qian.
Glycyrrhizae Radix et Rhizoma (Gancao, 甘草): Two qian.
Forsythiae Fructus (Lianqiao, 连翘): One qian.
Polyporus (Heishen, 黑参 - Note: Contextually likely refers to Scrophulariae Radix or similar cooling herb, literal translation Polyporus/Black Ginseng depending on specific lineage interpretation, here kept as Heishen): Two qian.
Bombyx Batryticatus (Jiangcan, 僵蚕): Seven fen, white ones, stir-fried.
Cimicifugae Rhizoma (Shengma, 升麻): Seven fen.
Bupleuri Radix (Chaihu, 柴胡): Eight fen.
Platycodonis Radix (Jiegeng, 桔梗): Five fen.
Isatidis Radix (Banlangen, 板蓝根): One qian.
Toad Venom (Mabo, 马勃): One qian.
Arctii Fructus (Niubangzi, 鼠粘子): One qian, stir-fried.
Grind the above into powder. Administer according to the method described above. Alternatively, add Saposhnikoviae Radix (Fangfeng, 防风), Ligustici Chuanxiong Rhizoma (Chuanxiong, 川芎), Menthae Haplocalycis Herba (Bohe, 薄荷), Angelicae Sinensis Radix (Guishen, 归身), and Asari Radix et Rhizoma (Xixin, 细辛), five qian each. Cut finely, decoct in water, and take slightly warm occasionally. If there is dry fecal impaction, add Rhubarb (Dahuang, 大黄) steamed with wine, one to two qian, to promote bowel movement. For severe swelling, apply Bian stone acupuncture (Phrenotomy/Bloodletting).
Luo Qianfu treated Yao Gongmao, Right Vice Director of the Department of State Affairs. He was sixty-seven years old and had a history of latent seasonal toxins. In the spring of Zhiyuan Wuchen year, the condition recurred due to alcohol consumption. His head, face, and ears swelled and hurt, with swelling around the ears being particularly severe. He experienced chest oppression and throat obstruction. The lower half of his body was cold, especially the calves. Consequently, beds and kang (heated brick beds) were connected; he slept on the bed with his upper body and on the kang with his lower body. His food intake decreased, and he suffered from mental fatigue and physical weakness. Luo Qianfu was summoned to treat him. The pulse was floating and rapid, but deep pressure revealed wiry and thin qualities, clearly indicating Upper Heat and Lower Cold. The *Neijing* states: Excessive heat leads to swelling. It also says: Diseases caused by Spring Qi often affect the head. The *Nanjing* states: Accumulation leads to swelling and heat, which should be treated with Bian stone puncture. This is done to facilitate dispersion. Therefore, approximately fifty punctures were made on the swollen area. The blood released was purple-black, resembling dewdrops. Within moments, the swelling and pain subsided. Then, one hundred moxa cones (Zhuang) were applied to the Qihai acupoint (CV6) to assist Yang deficiency in the Lower Jiao and dispel Yin cold. Next, thirty-seven moxa cones were applied to each of the Zusanli acupoints (ST36) to treat cold feet and guide the pathogenic heat downward. Finally, a prescription named Jiji Jiedu Tang (Ji Ji Antidote Decoction) was prescribed.
