大头瘟，这是由天行疠气（具有强烈传染性的外感病邪）引起的。湿热之邪侵袭人体最高处（头面部），必然导致汗出且热气蒸腾。初期表现为憎寒壮热、身体沉重，头部和面部肿胀严重，眼睛无法睁开，向上喘息，咽喉不利，舌干口燥。如果不迅速治疗，十个人中有八九个会死亡。适宜使用普济消毒散。如果大便干硬，加入酒蒸大黄一两到二钱，缓缓服用。制成丸药含化效果尤其好。如果额头及面部发红，面肿且脉数，属于阳明经病变，在原方基础上加石膏；体内实热重则加大黄。如果红肿发生在耳朵的上下前后以及额角旁边，这是少阳经病变，原方加柴胡、天花粉（栝蒌根）；大便实结也加大黄。如果红肿发生在头脑项下以及耳后，这是太阳经病变，使用荆防败毒散，去掉人参，加黄芩、黄连。病情严重的用砭石针刺放血。

Da Tou Wen (Big Head Plague) is caused by Tian Xing Li Qi (pestilential qi with strong infectivity). The damp-heat pathogen invades the highest part of the body (the head and face), inevitably leading to sweating and steaming heat. In the initial stage, it presents with aversion to cold and high fever, heavy body, severe swelling of the head and face, inability to open the eyes, upward panting, throat obstruction, dry tongue, and dry mouth. If not treated promptly, eight or nine out of ten patients will die. Pu Ji Xiao Du San (Universal Benefit Detoxification Powder) is suitable. If the stool is hard, add Jiu Zheng Da Huang (Wine-processed Rhubarb) 1-2 qian, taken slowly. Making pills for sucking is even better. If the forehead and facial area are red, with facial swelling and a rapid pulse, it belongs to the Yangming channel; add Shi Gao (Gypsum) to the original formula; if there is internal excess, add Da Huang (Rhubarb). If redness and swelling occur around the ears (above, below, front, back) and beside the frontal angle, this is Shaoyang channel involvement; add Chai Hu (Bupleurum) and Gua Lou Gen (Trichosanthes Root) to the original formula; if the stool is solid, also add Da Huang (Rhubarb). If redness and swelling occur at the back of the head and neck and behind the ears, this is Taiyang channel involvement; use Jing Fang Bai Du San (Schizonepeta and Saposhnikovia Decoction to Overcome Toxicity), remove Ren Shen (Ginseng), add Huang Qin (Scutellaria) and Lian Qiao (forbidden in text as 'Qin', likely Huang Qin based on context of clearing heat, but text says 'Qin, Lian' -> Huang Qin, Huang Lian); for severe cases, use Bian Shi (stone needle) acupuncture to bleed.
