罗谦甫治中书右丞姚公茂。六旬有七，宿有时毒，至元戊辰春，因酒再发，头面耳肿而疼，耳前后肿尤甚，胸
中烦闷，咽嗌不利，身半以下皆寒，足胫尤甚。由是以床相接作炕，身半以上卧于床，身半以下卧于炕，饮食减少，
精神困倦而体弱。命罗治之，诊得脉浮数，按之弦细，上热下寒明矣。《内经》云∶热胜则肿。又曰∶春气者病在
头。《难经》云∶蓄则肿热，砭射之也。盖取其易散故也。遂于肿上，约五十余刺，其血紫黑，如露珠之状，顷时
肿痛消散。又于气海中，大艾炷灸百壮，乃助下焦阳虚，退其阴寒，次三里二穴，各灸三七壮，治足 冷，亦引导热
气下行故也。遂处一方，名曰既济解毒汤。
靖康二年春季，京城爆发大规模瘟疫。有一位异人在书斋的墙壁上题写了一个药方，凡是因瘟疫导致身体肿胀的人，服用此方没有不有效的。该方由黑豆二合（炒至香熟）、甘草二寸（炙至黄色）组成，加水两盏，煎煮至剩下一半水量，不时小口饮用。
泰和二年四月，百姓中多患瘟疫。起初感觉怕冷、高热、身体沉重，随后传染至头面部严重肿胀，眼睛无法睁开，向上喘息，咽喉不利，舌干口燥。俗称“大头伤寒”，各种药物混合治疗都无法治愈，病情逐渐加重至危重程度。李东垣说：身体上半部，属于天的气机。邪热停留于心肺之间，向上攻冲头面而导致肿胀。必须使用以下药物，共同研成细末，一半用汤剂调服，不时服用；另一半制成蜜丸，含化服用，痊愈者很多。当时人都称这是仙方，说是由天仙所制。
黄芩（半两，酒炒） 黄连（五钱，酒炒） 人参（三钱） 陈皮（去白，二钱） 甘草（二钱） 连翘（一钱）
黑参（二钱） 僵蚕（七分，白色者，炒） 升麻（七分） 柴胡（八分） 桔梗（五分） 板蓝根（一钱） 马勃
（一钱） 鼠粘子（一钱，炒）
以上药物研为细末，服用方法如上所述。或者加入防风、川芎、薄荷、当归身、细辛各五钱，切碎后用水煎煮，不时稍温热服用。如果大便干燥结滞，加入酒蒸大黄一两二钱以通利大便；肿胀严重的，用砭石针刺放血。
罗谦甫治疗中书右丞姚公茂。他六十七岁，素有潜伏的时毒病症，到了至元戊辰年春季，因为饮酒再次发作，头面耳朵肿胀疼痛，耳前耳后肿胀尤其严重，胸中烦闷，咽喉不利，身体下半部分皆寒冷，小腿尤为严重。因此让人将床和炕连接起来，上半身睡在床上，下半身睡在炕上，饮食减少，精神困倦且身体虚弱。命令罗谦甫诊治，诊得脉象浮数，重按弦细，上热下寒的症状非常明显。《内经》说：热盛则导致肿胀。又说：春气致病多在头部。《难经》说：邪气蓄积则肿热，应用砭石刺破排脓。大概是取其易于消散的缘故。于是在肿胀处，大约刺了五十多针，流出的血液紫黑，像露珠一样，片刻间肿痛消散。又在气海穴，用大艾炷灸一百壮，以补助下焦阳虚，退去阴寒；接着灸足三里两个穴位，各灸三七壮，以治疗脚冷，也是引导热气下行的缘故。于是开出一个方子，名叫既济解毒汤。
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.
