（附∶大头天行病 虾蟆瘟）
论
《内经》曰∶苍天之气，清净则志意治，顺之则阳气固，虽有贼邪，弗能害也。又曰∶冬不藏精者，春必病瘟。是
以多感于房劳辛苦之人，安乐者未之有也。俗名瘟病，医书曰疫疠，曰黄病，岭南闽广等处曰瘴气，盖指山岚雾露烟瘴
湿热恶气而名之也，一皆触冒四时不正之气而为病焉。《伤寒论》曰∶春应温而反清，夏应热而反寒，秋应凉而反热，冬
应寒而反温。庞安常曰∶疫气之发，大则流行天下，次则一方，次则一乡，次则偏着一家，悉由气运郁发、有胜有伏、
迁正退位之所致也。视斯疾者，其可不推运气而治之乎。陶氏曰∶夫疫气之中人，轻重不一，仲景无治法，后人用败毒
散治，甚得理，然亦有愈不愈者，盖疫气有浅深，资禀有壮怯。怯而受疠气之深者，虽智者尚不能治，况庸劣之士乎。
若资禀壮实，所感又浅，则庶几可愈。切不可作伤寒正治而大汗大下也，但当从乎中治而用少阳、阳明二经药（少阳，
小柴胡汤；阳明，升麻葛根汤也），看所中阴阳经络脉证，而以二方加减和治之，殊为切当。学人宜详察之，毋忽。
脉法
脉阳濡弱，阴弦紧，更遇温气，变为瘟疫。
温病二、三日，体热腹满头痛，食饮如故，脉直而疾，八日死。
温病四、五日，头痛腹满而吐，脉来细而弦，十二日死。
温病八、九日，头身不疼，目不赤，色不变，而反利，脉来涩涩，按之不鼓手，时大，心下坚，十七日死。
温病汗不出，出不至足者死。厥逆汗自出，脉坚强急者生，虚软者死。
温病下利，腹中痛甚者死。
方法
丹溪曰∶众人病一般者，此天行时疫也，治有三法，宜补宜散宜降。用大黄、黄芩、黄连、人参、桔梗、苍术、防
风、滑石、香附、人中黄为末，神曲糊为丸，每服五、七十丸。气虚，以四君子汤下。血虚，以四物汤下。痰多，以二
陈汤下。热甚者，加童便（谓人中黄者，人粪也。今人多有以粪缸中清汁，顿饮一、二碗，病随愈。然但恐畏其臭秽，
不能下咽耳。故丹溪所取人中黄法，于冬月以竹截筒，削去青，两头留节，一头打通一窍，以大甘草纳入筒内，以竹钉
塞其窍，投粪缸中，二、三个月取出，晒干用）。
（以上丹溪方法凡一条）
陶尚文治瘟疫法∶
若病只在少阳经者，小柴胡加防风、羌活微发之而愈。若病兼阳明经者，柴、葛二方合服之（小柴胡对升麻葛根汤
也）。
若见太阳证，大便泄者，以本方（小柴胡也）去黄芩对五苓散，尤当看脉寒热，若无寒去桂留芩。
若小便不利，是膀胱本病，本方加去桂五苓散。
若入太阴经，无热证见者，用理中汤，此证必须腹痛而泻。明日泻止痛止，仍用小柴胡和之。
若入少阴经及厥阴经，用阴证伤寒传经法治之。
若初看未端的，且先以败毒散治之，看归在何经，再随经施治，无不效者。
若发黄，小柴胡合去桂五苓散。未退，茯苓渗湿汤。
瘟疫作渴，本方加石膏、知母。湿温渴，苍术白虎汤。
瘟疫发狂不识人，大柴胡汤加当归。如大便泄者，三黄石膏汤、柴苓汤。
瘟疫胸膈满闷，本方中加枳壳、橘红、黄连。若大便不通，大柴胡汤微利之。
三黄石膏汤
石膏（三钱） 黄芩 黄连 黄柏（各一钱五分） 豆豉（半合） 麻黄（一钱） 栀子（五枚）
上细切，作一服，水二盏，煎至一盏三分，连进三、五剂愈。

气散。
附∶大头天行病
丹溪曰∶大头病，乃湿热在高巅之上，用羌活及酒炒黄芩、酒蒸大黄，随病加减，切不可用降药。
东垣曰∶阳明邪热太甚，实资少阳相火而为之也。湿热为肿，火盛为痛，此邪见于头，多在两耳前后先出，皆主其
病也。治法大不宜速药，速则过其病所，谓上热未除，中寒复生，必伤人命。宜用缓药缓服，徐徐少与，当视其肿势在
何部分，随经处治之。阳明为邪首大肿，少阳为邪出于耳项前后也。
二黄汤（东垣） 治大头天行疫病。

上细切，每服三钱，水一盏，煎七分，温服，徐徐呷之。如未退，用鼠粘子不拘多少，水煎，入芒硝等分，亦时时
少与，毋令饮食在后。如未已，只服前药，取大便利、邪气已则止。
前方宜各少加引经药，阳明渴，加石膏，少阳渴，加栝蒌根，阳明行经，升麻、芍药、葛根、甘草，太阳行经，甘
草、荆芥、防风，并与上药相合用之。或云∶头痛酒芩，口渴干葛，身痛羌活、桂枝、防风、芍药，俱宜加之。
普济消毒饮子（东垣） 泰和二年四月，民多疫疠，初觉憎寒壮热体重，次传头面肿盛，目不能开，上喘咽喉
不
利，舌干口燥，俗云大头伤寒，诸药杂治，终莫能愈，渐至危笃。东垣曰∶身半以上，天之气也。邪热客于心肺之间，
上攻头面而为肿耳。须用下项药共为细末，半用汤调时时服之，半用蜜丸噙化，服尽良愈，活者甚众。时人皆曰天方，
谓天仙所制也。遂刻诸石，以传永久。

病，从 颔肿热者，又名颅HT 瘟，东垣有方用羌活、酒炒黄芩、酒蒸大黄加减，水煎服。十五、六日，服小柴胡汤不
愈者，仍用陈皮、紫苏发散而愈。又法∶洒炒黄芩、黄连为君，炙甘草为佐，水煎，细细呷之。再加鼠粘子、酒蒸大黄
煎，入芒硝，亦细细频与服之，微利为度。肿减后，去后三味，只服前药。如渴，属阳明，加石膏；属少阳，加栝蒌根。
若阳明行经，加升麻、芍药、葛根、甘草；太阳行经，加羌活、荆芥、防风。如头痛，加黄芩；渴，加葛根；身痛，加

水浆不下，或面赤，脉浮洪，热甚，漏芦汤治之。升麻、黄芩、大黄各一两，蓝叶（即大青叶）、玄参各二两，煎服。
（丹溪活套）云∶众人病一般者，乃天行时疫。盖冬月闭藏之时，反行春令，温胜于寒，而发泄真阴，土胜水亏矣。
所胜者妄行，土有余也。所生者受病，所胜者侮之，火土相合，湿热相聚。故春来木长之时，无水滋生化源，故人病瘟。
治有三法，见前。春感清气，无汗恶寒，为疫疠，通用升麻葛根汤。春感清气，发热而渴，不恶寒，宜解肌汤，葛根、
黄芩、芍药各一钱，麻黄一钱半，甘草、桂枝各七分半，大枣一枚，水煎服。春温，发热咳嗽，身疼口燥渴，脉浮洪热
甚，宜小柴胡汤加桂枝治之。咳嗽，加五味子。渴，去半夏，加栝蒌根、人参。脉实渴，宜大柴胡汤下之。渴，加知母、
石膏。凡温病，脉尺寸俱浮，素伤于风，因而伤热，风热相搏。其证四肢不收，身热自汗，头痛喘息，发渴昏睡，或体
重不仁。慎勿发汗，汗之则谵语烦躁，目昧无睛光。病在少阴厥、阴二经，宜萎蕤汤、人参败毒散、葛根龙胆汤、小柴
胡汤。甚者，栝蒌葛根汤。脉浮身肿汗出，汉防己汤。误汗者，防己黄 汤。四时伤寒疫疠，或伤风有汗，或风湿，身
肿体痛，恶风口干，日晡潮热，脉实，并用人参败毒散。夏应热而反寒，夏及秋初而为暴寒，折于盛暑，热结四肢，则
壮热头痛，或寒伤于胃，下利脓血或水泻，脉实者宜下之安。调中汤加∶大黄三钱，葛根、黄芩等药各二钱。
（医案）
东阳李文会内子陈氏，年二十九，三月间得瘟疫证，病三日经水适来，发热愈甚，至七、八日病剧，胸中气筑作痛，
莫能卧。众医技穷辞去，黑夜来迎予延医。病者以绵花袋盛托背而坐于床，令婢磨胸不息，手六脉俱微，数极而无伦次，
又若虾游状。予问曰∶恐下早成结胸耳？主人曰∶未曾下。予再思之，三日而经水适来，致中气虚，与下同。用黄龙汤、
四物汤、小陷胸汤共合一剂，加姜、枣煎服。主人曰∶此药何名？予曰∶三合汤也。一服而诸病悉减，遂能卧。再服，
热退而病全安。愈后，又因食粥太多而病复热，又作内伤处治，而用补中益气汤出入加减调理而愈。
论说
《黄帝内经》说：苍天之气，如果清净平和，人的意志就能安定；顺应这种气候，阳气就能固密，即使有贼邪之气，也不能伤害人体。又说：冬天如果不注意藏精，春天必定会患瘟疫。因此，这类疾病多发生于房事过度、劳累辛苦的人身上，安乐享福的人很少得病。民间俗称瘟病，医书中称为疫疠、黄病，在岭南、福建、广东等地称为瘴气，这都是指山间雾气、露水、烟雾、湿热等恶浊之气而得名，都是因为触犯四时不正之气而致病。《伤寒论》说：春天应当温暖却反而清冷，夏天应当炎热却反而寒冷，秋天应当凉爽却反而炎热，冬天应当寒冷却反而温暖。庞安常说：疫气的发作，大的可以流行天下，次之流行一方，再次之流行一乡，更小的只局限于一家，这都是由于运气郁结爆发、胜复伏留、主气迁正退位所导致的。诊治这种疾病，怎能不推求运气规律来治疗呢？陶氏说：疫气伤人，病情轻重不一，张仲景没有制定治法，后人用败毒散治疗，很符合医理，然而也有治不好的人，这是因为疫气有浅深之分，体质禀赋有强弱之别。体质虚弱又感染深重疫气的人，即使是名医尚且难以治愈，何况平庸低劣的医生呢？如果体质壮实，感受的疫气又浅，那么或许可以痊愈。切不可当作普通伤寒进行正统治疗而使用大汗、大下之法，而应当从乎中治，使用少阳、阳明二经的药物（少阳经用小柴胡汤；阳明经用升麻葛根汤），根据所中的阴阳经络脉证，对这两个方剂进行加减调和治疗，非常恰当。学者应当详细考察，不要忽视。
脉法
脉象阳部濡弱，阴部弦紧，如果再遇到温气，就会变为瘟疫。
温病两三天，身体发热、腹部胀满、头痛，饮食如常，脉象直而疾速，八天后死亡。
温病四五天，头痛、腹部胀满且呕吐，脉象细而弦，十二天后死亡。
温病八九天，头身不疼痛，眼睛不红，面色无变化，反而出现腹泻，脉象涩滞，按之无力且不鼓手，时而变大，心下坚硬，十七天后死亡。
温病汗不出，或者出汗不到足部的，死亡。四肢厥逆但自汗出，脉象坚强急迫的能生，脉象虚软的死亡。
方法
朱丹溪说：众人得病症状相同的，这是天行时疫，治疗有三种方法，宜补、宜散、宜降。用大黄、黄芩、黄连、人参、桔梗、苍术、防风、滑石、香附、人中黄研为末，神曲糊制成丸药，每次服用五七十丸。气虚的，用四君子汤送服。血虚的，用四物汤送服。痰多的，用二陈汤送服。热势严重的，加童便（所谓人中黄，就是人粪。现在很多人直接饮用粪缸中的清汁一两碗，病随即痊愈。但这只是人们害怕其臭秽，不能咽下罢了。所以丹溪取用的人中黄制法，是在冬天截取竹筒，削去青皮，两头保留竹节，一头打通一个小孔，将大甘草纳入筒内，用竹钉塞住小孔，投入粪缸中，两三个月后取出，晒干使用）。
（以上丹溪的方法共一条）
如果病只在少阳经，用小柴胡汤加防风、羌活轻微发汗即可痊愈。如果病兼涉阳明经，小柴胡汤和升麻葛根汤合服。
如果见到太阳证，大便泄泻的，用本方（即小柴胡汤）去掉黄芩，配合五苓散，尤其应当看脉象寒热情况，如果没有寒象，就去掉桂枝保留黄芩。
如果小便不利，这是膀胱的本病，在本方中加入去掉桂枝的五苓散。
如果病入太阴经，没有热证表现的，用理中汤，此证必须伴有腹痛和腹泻。第二天如果腹泻停止、疼痛消失，仍用小柴胡汤调和。
如果初诊时不能确切判断，先以败毒散治疗，观察病邪归于哪一经，再随经施治，没有不有效的。
如果出现发黄，用小柴胡汤合去掉桂枝的五苓散。未消退的，用茯苓渗湿汤。
瘟疫导致口渴，本方加石膏、知母。湿温导致口渴，用苍术白虎汤。
瘟疫导致发狂、不识人，用大柴胡汤加当归。如果大便泄泻，用三黄石膏汤、柴苓汤。
瘟疫导致胸膈满闷，本方中加枳壳、橘红、黄连。如果大便不通，用大柴胡汤轻微通利。
三黄石膏汤
石膏（三钱） 黄芩 黄连 黄柏（各一钱五分） 豆豉（半合） 麻黄（一钱） 栀子（五枚）
以上切碎，作一服药，用水两盏，煎至一盏三分，连续服用三到五剂可愈。
败毒散 治疗瘟疫。（四季通用。）
羌活 独活 前胡 柴胡 川芎 枳壳 桔梗 白茯苓 人参（各等分） 甘草（减半）
以上研为细末，每次服用三钱，加生姜三片，水一盏半，煎至一盏，温服，或者用沸水冲服也可以。此药治疗伤寒瘟疫、风湿风眩、四肢疼痛、憎寒壮热、项强睛疼，不问老人、小儿都可以服用。或者是岭南烟瘴之地，或者瘟疫流行，或者人多风痰，或者处于卑湿之地，脚气痿弱，此药不可缺。每天三到五次服用，以见效为度。另一配方加少许薄荷，每次服用五钱，加姜，水煎服。
九味羌活汤（方见伤寒门。） 治疗瘟疫初感，一两天间服用，取汗而愈，效果如神。
黑奴丸 治疗瘟毒发斑、烦躁大渴，以及时行热病，六七天未得汗，脉洪大而数，面赤目眩，身痛大热，胡言乱语想跑动，极度口渴。又说：五六日以上不解，热在胸中，口噤不能说话，属于坏伤寒，医生无法治疗，被放弃视为死人，精气已竭，但心下尚温，撬开嘴灌药，咽下则活。
黄芩 釜底煤 芒硝 麻黄 梁上尘 小麦奴 灶突墨（各一两） 大黄（一两三钱）
以上研为细末，炼蜜为丸，如弹子大小，新汲水化开服用，饮水尽后应当发冷，冷过之后汗出，病就好了。如果片刻不出汗，再服一丸，必须见到轻微腹泻。如果不渴，不可给此药。
神术散（太无方） 治疗四时瘟疫，头痛项强，憎寒壮热，身痛，是专门主治山岚瘴气的妙剂。
陈皮（二钱） 苍术 浓朴（各一钱） 甘草 藿香 石菖蒲（各一钱五分）
以上切碎，作一服药，加姜三片，大枣一枚，水一盏半，煎至一盏，去渣温服。另一配方无菖蒲，有一钱香附，名叫神术散气散。
附注：大头天行病
朱丹溪说：大头病，是湿热在高巅之上，用羌活及酒炒黄芩、酒蒸大黄，随病情加减，切不可用降药。
李东垣说：阳明邪热太甚，实际上是借助少阳相火造成的。湿热导致肿胀，火盛导致疼痛，这种邪气见于头部，多在两耳前后先出现，都主治其病。治疗方法大不宜用猛药，猛药则会超过病所，谓上热未除，中寒复生，必伤人命。宜用缓药缓服，慢慢少量给予，应当观察肿势在哪个部分，随经处治。阳明经受邪头部肿大，少阳经受邪出于耳项前后。
二黄汤（东垣方） 治疗大头天行疫病。
黄芩（酒制炒） 黄连（酒制炒） 生甘草（各等分）
以上切碎，每次服用三钱，水一盏，煎七分，温服，慢慢呷饮。如果未消退，用鼠粘子不拘多少，水煎，入芒硝等分，也时时少量给予，不要让饮食落在后面。如果仍未好，只服前药，取大便通畅、邪气已除为止。
前方宜各少加引经药，阳明经口渴，加石膏，少阳经口渴，加栝蒌根，阳明经行经药，升麻、芍药、葛根、甘草，太阳经行经药，甘草、荆芥、防风，并与上药相合用。或者说：头痛用酒芩，口渴用干葛，身痛用羌活、桂枝、防风、芍药，都适宜加上。
普济消毒饮子（东垣方） 泰和二年四月，百姓多患疫疠，起初觉得憎寒壮热体重，随后传染头面肿盛，眼睛不能睁开，向上喘促咽喉不利，舌干口燥，俗叫大头伤寒，各种药物杂治，最终不能痊愈，逐渐危重。东垣说：身半以上，是天之气。邪热客居在心肺之间，上攻头面而导致肿胀。须用下列药物共为细末，一半用汤调时时服用，一半用蜜丸含化，服完良愈，救活的人很多。当时人都叫它天方，说是天仙所制。于是刻在石头上，以流传永久。
黄芩（五钱，酒制炒） 黄连（五钱，酒制炒） 人参（三钱） 陈皮（去白，二钱） 甘草（二钱） 连翘（一钱） 玄参（二钱） 白僵蚕（七分，炒） 升麻（七分） 柴胡（五分） 桔梗（三分） 板蓝根（一钱） 马勃（一钱） 鼠粘子（一钱）
以上研为末，服用如上法。或者加防风、川芎、薄荷、当归身，切碎五钱，水两盏，煎至一盏，食后稍热时服用。如果大便硬，加酒蒸大黄一钱或二钱以通利之。肿势严重的，用砭针刺之。
附注：虾蟆瘟
朱丹溪说：虾蟆瘟，属风热，用防风通圣散加减治疗。或者用小柴胡汤加防风、羌活、荆芥、薄荷、桔梗煎服，外用侧柏叶捣汁，混合蚯蚓粪敷之。或者用丁香尖、附子尖、南星，醋调敷之。或者五叶藤、车前草皆可捣敷，有效。
甘桔汤 治疗冬瘟，咽喉肿痛。
甘草 桔梗（各等分。）
以上切碎，水煎，时时频饮。
萎蕤散 治疗冬瘟，头面肿。
萎蕤（二钱五分） 石膏（一钱五分） 麻黄 白薇 羌活 杏仁 甘草
青木香 川芎（各五分） 干菊花（一钱五分）
以上切碎，作一服药，水两盏，煎至一盏，去渣，每天三次服用。
（祖传方）
人黄散 治疗四时疫疠，大头天行等病。
甘草（三钱） 辰砂 雄黄（各一钱五分） 粪缸岸（置于风露中年久者佳，水飞细研，一两重）
以上研为细末，每次服用三钱，煎薄荷桔梗汤送下，每天三到五次服用。煎药：甘草、桔梗、茯苓、本、白术各五分，水煎服。
疫疠，夏天感受寒邪，伏于少阴，咽痛，随后必然下利，名叫肾伤寒，宜用半夏、桔梗、甘草各一钱，加姜五片，煎服。大头天行病，从颔下肿热的，又名颅HT瘟，东垣有方用羌活、酒炒黄芩、酒蒸大黄加减，水煎服。十五六日，服小柴胡汤不愈的，仍用陈皮、紫苏发散而愈。又一种方法：洒炒黄芩、黄连为君药，炙甘草为佐药，水煎，细细呷饮。再加鼠粘子、酒蒸大黄煎，入芒硝，也细细频繁服用，以微利为度。肿减后，去掉后三味，只服前药。如果口渴，属阳明经，加石膏；属少阳经，加栝蒌根。如果阳明经行经，加升麻、芍药、葛根、甘草；太阳经行经，加羌活、荆芥、防风。如果头痛，加黄芩；口渴，加葛根；身痛，加羌活、防风、荆芥、桂枝、芍药，随意使用，加入上药相合煎服。或者时疫肿毒疙瘩，或者脏腑积热，发于头项，咽喉堵塞，水浆不下，或者面赤，脉浮洪，热甚，用漏芦汤治疗。升麻、黄芩、大黄各一两，蓝叶（即大青叶）、玄参各二两，煎服。
（丹溪活套）说：众人得病症状相同的，乃天行时疫。因为冬天是闭藏之时，反而施行春令，温胜于寒，而发泄真阴，土胜水亏矣。所胜者妄行，是因为土有余。所生者受病，所胜者侮之，火土相合，湿热相聚。所以春天木气生长之时，无水滋生化源，所以人患瘟病。治疗有三种方法，见前文。春天感受清气，无汗恶寒，为疫疠，通用升麻葛根汤。春天感受清气，发热而渴，不恶寒，宜解肌汤，葛根、黄芩、芍药各一钱，麻黄一钱半，甘草、桂枝各七分半，大枣一枚，水煎服。春温，发热咳嗽，身疼口燥渴，脉浮洪热甚，宜小柴胡汤加桂枝治疗。咳嗽，加五味子。口渴，去半夏，加栝蒌根、人参。脉实口渴，宜大柴胡汤下之。口渴，加知母、石膏。凡是温病，脉尺寸俱浮，素伤于风，因而伤热，风热相搏。其证四肢不收，身热自汗，头痛喘息，发渴昏睡，或者体重不仁。千万不要发汗，发汗则谵语烦躁，目昧无睛光。病在少阴厥阴二经，宜萎蕤汤、人参败毒散、葛根龙胆汤、小柴胡汤。严重的，用栝蒌葛根汤。脉浮身肿汗出，用汉防己汤。误汗的，用防己黄芪汤。四时伤寒疫疠，或者伤风有汗，或者风湿，身肿体痛，恶风口干，日晡潮热，脉实，并用人参败毒散。夏天应当热却反而寒，夏及秋初而为暴寒，折于盛暑，热结四肢，则壮热头痛，或者寒伤于胃，下利脓血或水泻，脉实者宜下之安。调中汤加：大黄三钱，葛根、黄芩等药各二钱。

东阳李文会的妻子陈氏，年龄二十九岁，三月间得了瘟疫证，病了三天月经正好来了，发热更加严重，到了七八天病情加重，胸中气筑作痛，不能躺卧。众医技穷辞去，黑夜来迎我延请医生。病人用棉花袋垫背坐在床上，让婢女不停按摩胸部，手六脉都微弱，数极而无伦次，又像虾游状。我问：恐怕是下早了形成结胸吗？主人说：未曾下。我再思考，三天而月经正好来，导致中气虚，与下同。用黄龙汤、四物汤、小陷胸汤共合一剂，加姜、枣煎服。主人问：这药叫什么名？我说：三合汤也。一服而诸病悉减，遂能卧。再服，热退而病全安。痊愈后，又因吃粥太多而病复发热，又作内伤处理，而用补中益气汤出入加减调理而愈。
[Appendix: Da Tou Tian Xing Bing (Big Head Plague) and Xia Ma Wen (Toad Plague]
Treatise
The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: When the Qi of Heaven is pure and peaceful, human will and intention are regulated; complying with this climate, Yang Qi becomes solid. Even if there are pathogenic factors, they cannot harm the body. It also states: Those who fail to conserve essence in winter will inevitably suffer from epidemics in spring. Therefore, such diseases mostly affect those who have engaged in excessive sexual activity or hard labor, while those living in comfort rarely contract them. Commonly known as "Wen Bing" (Plague Disease), medical texts refer to it as "Yi Li" (Epidemic Pestilence) or "Huang Bing" (Yellow Disease). In regions like Lingnan, Fujian, and Guangdong, it is called "Zhang Qi" (Miasma). This term refers to the foul Qi arising from mountain mists, dew, smoke, dampness, heat, and other turbid environmental factors. All these illnesses result from exposure to the abnormal Qi of the four seasons. The *Shanghan Lun* (Treatise on Cold Damage) states: Spring should be warm but turns cold; summer should be hot but turns cold; autumn should be cool but turns hot; winter should be cold but turns warm. Pang Anchang said: The onset of epidemic Qi can spread across the world, a region, a village, or even just one family. This is caused by the stagnation and eruption of climatic cycles, including excess, deficiency, retention, and the shifting of ruling Qi. When treating such diseases, how can one neglect analyzing the climatic cycles? Tao Shi stated: Epidemic Qi affects people with varying severity. Zhang Zhongjing did not prescribe specific treatments for it. Later physicians used Bai Du San (Decoction to Overcome Toxicity), which aligns well with medical principles, yet some patients do not recover. This is because epidemic Qi has depths of penetration, and constitutional endowments vary in strength. For those with weak constitutions who have absorbed deep-seated epidemic Qi, even wise physicians may struggle to cure them, let alone mediocre ones. However, if the constitution is robust and the infection is superficial, recovery is likely. One must absolutely avoid treating it as ordinary Shang Han (Cold Damage) with drastic sweating or purging methods. Instead, treatment should follow the principle of "treating from the middle," using herbs from the Shaoyang and Yangming meridians (Shaoyang: Xiao Chai Hu Tang; Yangming: Sheng Ma Ge Gen Tang). Based on the affected Yin-Yang meridians and pulse/symptom patterns, these two formulas should be modified and harmonized, which is highly appropriate. Scholars should examine this carefully and not neglect it.
Pulse Diagnosis
If the Yang position pulse is Ru (Soggy) and Ruo (Weak), and the Yin position pulse is Xian (String-taut) and Jin (Tight), compounded by warm Qi, it transforms into an epidemic plague.
In Wen Bing (Warm Disease) lasting two to three days, with fever, abdominal fullness, headache, but normal appetite, and a straight, rapid pulse, death occurs after eight days.
In Wen Bing lasting four to five days, with headache, abdominal fullness, vomiting, and a fine, string-taut pulse, death occurs after twelve days.
In Wen Bing lasting eight to nine days, without head/body pain, red eyes, or color changes, but with diarrhea, a choppy pulse that feels weak upon pressure and fluctuates in size, along with hardness below the heart, death occurs after seventeen days.
In Wen Bing, if sweat does not appear, or if sweating does not reach the feet, death ensues. If limbs are cold with spontaneous sweating, a firm, strong, urgent pulse indicates survival, while a deficient, soft pulse indicates death.
In Wen Bing with diarrhea, severe abdominal pain indicates death.
Methods
Zhu Danxi said: When everyone suffers from similar symptoms, it is a seasonal epidemic. There are three treatment approaches: tonification, dispersion, and descending. Use Da Huang (Rhubarb Root), Huang Qin (Scutellaria Root), Huang Lian (Coptis Rhizome), Ren Shen (Ginseng Root), Jie Geng (Platycodon Root), Cang Zhu (Atractylodes Rhizome), Fang Feng (Saposhnikovia Root), Hua Shi (Talcum), Xiang Fu (Cyperus Rhizome), and Ren Zhong Huang (Human Waste Product) powdered together. Form pills with Shen Qu (Medicated Leaven). Take 50-70 pills per dose. For Qi deficiency, administer with Si Jun Zi Tang (Four Gentlemen Decoction). For Blood deficiency, administer with Si Wu Tang (Four Substances Decoction). For excessive phlegm, administer with Er Chen Tang (Two Aged Ingredients Decoction). For severe heat, add Tong Bian (Child's Urine). [Note: Ren Zhong Huang is human feces. Many people now drink clear liquid from fecal pits directly, curing the disease instantly. However, people fear the foul odor. Thus, Danxi's method involves cutting bamboo tubes in winter, removing the green skin, leaving nodes at both ends, drilling a hole in one end, inserting large Gan Cao (Licorice Root), sealing the hole with a bamboo peg, and immersing it in a fecal pit for 2-3 months before drying.]
(Above: Danxi's method, one entry)
Tao Shangwen's method for treating plague:
If the disease is confined to the Shaoyang Meridian, use Xiao Chai Hu Tang (Minor Bupleurum Decoction) plus Fang Feng (Saposhnikovia Root) and Qiang Huo (Notopterygium Rhizome) to induce slight sweating for recovery. If the disease involves the Yangming Meridian, combine Xiao Chai Hu Tang and Sheng Ma Ge Gen Tang (Bunge Magnolia Bud and Kudzu Root Decoction).
If Taiyang syndrome is present with loose stools, remove Huang Qin from the base formula (Xiao Chai Hu Tang) and combine with Wu Ling San (Five-Ingredient Powder with Poria). Pay close attention to pulse indications of cold/heat; if no cold signs exist, remove Gui Zhi (Cinnamon Twig) and retain Huang Qin.
If urination is difficult, indicating a primary Bladder issue, add Wu Ling San (without Gui Zhi) to the base formula.
If the disease enters the Taiyin Meridian without heat signs, use Li Zhong Tang (Regulate the Middle Decoction). This condition must involve abdominal pain and diarrhea. If diarrhea and pain cease the next day, resume Xiao Chai Hu Tang to harmonize.
If the disease enters the Shaoyin or Jueyin meridians, treat according to the transmission rules of Yin-pattern Cold Damage.
If the initial diagnosis is unclear, first treat with Bai Du San (Decoction to Overcome Toxicity). Observe which meridian the pathogen settles in, then treat accordingly. This approach is invariably effective.
If jaundice appears, combine Xiao Chai Hu Tang with Wu Ling San (without Gui Zhi). If unresolved, use Fu Ling Shen Shi Tang (Poria Dampness-Draining Decoction).
For plague-induced thirst, add Shi Gao (Gypsum Fibrosum) and Zhi Mu (Anemarrhena Rhizome) to the base formula. For damp-warmth-induced thirst, use Cang Zhu Bai Hu Tang (Atractylodes White Tiger Decoction).
For plague-induced mania and confusion, use Da Chai Hu Tang (Major Bupleurum Decoction) plus Dang Gui (Angelica Sinensis Root). If accompanied by diarrhea, use San Huang Shi Gao Tang (Three Yellows and Gypsum Decoction) or Chai Ling Tang (Bupleurum and Poria Decoction).
For plague-induced chest/epigastric fullness and oppression, add Zhi Ke (Aurantii Fructus), Ju Hong (Citretum Reticulatum Pericarpium Rubrum), and Huang Lian to the base formula. If constipation exists, use Da Chai Hu Tang to mildly purge.

This medicine treats Shang Han, plague, wind-dampness, wind-dizziness, limb pain, aversion to cold with high fever, stiff neck, eye pain. Suitable for elderly and children alike. Essential in Lingnan miasma regions, during plague outbreaks, for those with wind-phlegm, in low/damp areas, or for foot weakness (Hong Kong Foot). Take 3-5 times daily until effective. Another variation adds mint; take 5 qian with ginger and water.
Jiu Wei Qiang Huo Tang (Nine-Ingredient Notopterygium Decoction) [See Shang Han Section] - Treats early-stage plague. Take within 1-2 days to induce sweating and cure. Effect is miraculous.
Hei Nu Wan (Black Slave Pill) - Treats plague-toxic macules, irritability, extreme thirst, and seasonal febrile diseases where no sweat has occurred after 6-7 days, with surging, rapid pulse, red face, dizzy eyes, body pain, high fever, delirium, restlessness, and extreme thirst. Also for cases unresolved after 5-6 days, heat in the chest, locked jaw unable to speak, classified as "ruined Shang Han" deemed untreatable and abandoned. If the spirit is exhausted but the epigastrium remains warm, pry open the mouth and administer; survival is possible.
Huang Qin (Scutellaria Root, 1 liang), Fu Di Mei (Soot from Cauldron Bottom, 1 liang), Mang Xiao (Mirabilite, 1 liang), Ma Huang (Ephedra Herb, 1 liang), Liang Shang Chen (Dust from Roof Beam, 1 liang), Xiao Mai Nu (Sprouts of Wheat, 1 liang), Zao Tu Mo (Soot from Chimney Flue, 1 liang); Da Huang (Rhubarb Root, 1.3 liang).

Appendix: Da Tou Tian Xing Bing (Big Head Plague)
Zhu Danxi said: Big Head Disease is caused by damp-heat rising to the highest points. Use Qiang Huo, wine-fried Huang Qin, and wine-steamed Da Huang, modified according to the condition. Absolutely avoid descending medicines.
Li Dongyuan said: Excessive Yangming pathogenic heat relies on Shaoyang Minister Fire to manifest. Damp-heat causes swelling; fire excess causes pain. This pathogen manifests on the head, often appearing first around both ears. Treatment should avoid rapid/strong drugs; speed causes the remedy to overshoot the pathology, leading to residual upper heat and new middle cold, potentially fatal. Use slow-acting drugs administered slowly in small amounts. Observe the location of swelling to treat via the relevant meridian. Yangming involvement causes major head swelling; Shaoyinvolution causes swelling around ears and neck.
Er Huang Tang (Two Yellows Decoction) [Dongyuan Formula] - Treats Big Head Plague.
Huang Qin (Scutellaria Root, wine-fried), Huang Lian (Coptis Rhizome, wine-fried), Sheng Gan Cao (Raw Licorice Root) [equal parts].
Cut finely. Take 3 qian per dose in 1 cup of water, decoct to 0.7 cups. Take warm, sipping slowly. If unresolved, use Niu Bang Zi (Arctii Fructus) in any amount, decocted with equal parts Mang Xiao. Administer frequently in small amounts, avoiding food intake afterwards. If still unresolved, continue the previous formula until bowel movements become free and pathogenic Qi is expelled.
Add meridian-guiding herbs to the above formulas: For Yangming thirst, add Shi Gao; for Shaoyang thirst, add Gua Lou Gen (Trichosanthes Root). For Yangming meridian guidance, use Sheng Ma, Shao Yao, Ge Gen, Gan Cao; for Taiyang, use Gan Cao, Jing Jie, Fang Feng. Alternatively: Wine-fried Huang Qin for headache; Ge Gen for thirst; Qiang Huo, Gui Zhi, Fang Feng, Shao Yao for body pain.
Pu Ji Xiao Du Yin Zi (Universal Benefit Detoxifying Decoction) [Dongyuan Formula] - In the second year of Taihe, April, many suffered epidles. Initially feeling aversion to cold, high fever, and heaviness, progressing to severe head/face swelling, inability to open eyes, upper wheezing, throat obstruction, dry tongue/mouth. Commonly called "Big Head Shang Han." Various treatments failed, leading to critical conditions. Dongyuan stated: The upper half of the body corresponds to Heaven's Qi. Pathogenic heat lodging between Heart and Lung attacks the head/face causing swelling. Use the following ingredients powdered: Half taken as a tea decoction frequently; half formed into honey pills for sucking. Full recovery was achieved, saving many lives. People called it "Tian Fang" (Heavenly Prescription), believing it was made by immortals. It was carved on stone for posterity.
Huang Qin (5 qian, wine-fried), Huang Lian (5 qian, wine-fried), Ren Shen (3 qian), Chen Pi (2 qian, pith removed), Gan Cao (2 qian), Lian Qiao (1 qian), Xuan Shen (2 qian), Bai Jiang Can (0.7 qian, fried), Sheng Ma (0.7 qian), Chai Hu (0.5 qian), Jie Geng (0.3 qian), Ban Lan Gen (1 qian), Ma Bo (1 qian), Niu Bang Zi (1 qian).

Appendix: Xia Ma Wen (Toad Plague)
Zhu Danxi said: Toad Plague belongs to Wind-Heat. Use Fang Feng Tong Sheng San (Wind-Barrier Releasing Strength Decoction) modified. Or use Xiao Chai Hu Tang plus Fang Feng, Qiang Huo, Jing Jie, Bo He, Jie Geng decocted externally apply crushed Ce Bai Ye (Biota Tops) juice mixed with Earthworm excrement. Or apply Ding Xiang Jian (Clove Tip), Fu Zi Jian (Aconite Tip), Nan Xing (Arisaema Rhizome) mixed with vinegar. Or crush Wu Ye Teng (Uncaria Vine) or Che Qian Cao (Plantago Herb) for external application. Effective.
Gan Jie Tang (Licorice and Platycodon Decoction) - Treats Winter Plague, sore/swollen throat.
Gan Cao, Jie Geng [equal parts].
Cut finely, decoct in water, sip frequently.
Wei Yu San (Polygonatum Powder) - Treats Winter Plague, head/face swelling.
Wei Yu (Polygonatum Rhizome, 2.5 qian), Shi Gao (Gypsum Fibrosum, 1.5 qian), Ma Huang (Ephedra Herb), Bai Wei (Cynanchum Root), Qiang Huo (Notopterygium Rhizome), Xing Ren (Apricot Seed), Gan Cao (Licorice Root), Qing Mu Xiang (Costus Root), Chuan Xiong (Ligusticum Rhizome) [all 0.5 qian], Gan Ju Hua (Chrysanthemum Flower, 1.5 qian).
Cut finely, decoct one dose in 2 cups water to 1 cup. Strain. Take 3 times daily.
(Ancestral Formula)
Ren Huang San (Human Yellow Powder) - Treats four-season plagues, Big Head Plague, etc.
Gan Cao (3 qian), Chen Sha (Cinnabar), Xiong Huang (Realgar) [each 1.5 qian], Fen Gang An (Fecal Pit Bank Soil, aged in wind/dew for years, water-pulverized fine, 1 liang).
Powder finely. Take 3 qian per dose, washed down with Bo He Jie Geng Tang (Mint and Platycodon Decoction). Take 3-5 times daily. Decoction for washing: Gan Cao, Jie Geng, Fu Ling, Ben Cao, Bai Zhu [each 0.5 qian], decoct in water.
Plague contracted in summer due to cold lying hidden in Shaoyin causes sore throat, followed by diarrhea, named "Kidney Shang Han." Use Ban Xia, Jie Geng, Gan Cao [each 1 qian] plus 5 slices ginger, decoct. For Big Head Plague with submandibular swelling/hotness, also called "Skull HT Plague," Dongyuan's formula uses Qiang Huo, wine-fried Huang Qin, wine-steamed Da Huang modified, decocted. If unresolved after 15-16 days on Xiao Chai Hu Tang, use Chen Pi and Zi Su for dispersion. Another method: Wine-fried Huang Qin and Huang Lian as sovereign, roasted Gan Cao as minister, decoct and sip slowly. Add Niu Bang Zi and wine-steamed Da Huang decocted with Mang Xiao, sip frequently until mild diarrhea. After swelling reduces, stop the last three ingredients, continue previous formula. For thirst: Yangming pattern add Shi Gao; Shaoyang pattern add Gua Lou Gen. For Yangming meridian guidance, add Sheng Ma, Shao Yao, Ge Gen, Gan Cao; for Taiyang, add Qiang Huo, Jing Jie, Fang Feng. For headache, add Huang Qin; for thirst, add Ge Gen; for body pain, add Qiang Huo, Fang Feng, Jing Jie, Gui Zhi, Shao Yao. Combine with main formula. For epidemic toxic nodules or internal organ heat erupting on head/neck causing throat blockage preventing swallowing, red face, floating/surging pulse, severe heat, use Lu Lu Tang. Sheng Ma, Huang Qin, Da Huang [each 1 liang], Lan Ye (Da Qing Ye, 2 liang), Xuan Shen (2 liang), decoct.
(Danxi's Flexible Approach) states: When everyone suffers similarly, it is a seasonal epidemic. Winter is for storage, but if Spring-like warmth prevails over cold, True Yin is leaked, Earth overcomes Water. Excess Earth acts recklessly. Generated elements suffer; overcoming elements insult. Fire and Earth combine, creating damp-heat. When Spring Wood grows, lacking Water to nourish the source, humans get plague. Three treatment methods exist (see above). Spring清气 (Clear Qi) with no sweat/aversion to cold = Plague, use Sheng Ma Ge Gen Tang. Spring Clear Qi with fever/thirst/no aversion to cold = Use Jie Ji Tang (Ge Gen, Huang Qin, Shao Yao each 1 qian; Ma Huang 1.5 qian; Gan Cao, Gui Zhi each 0.75 qian; 1 Jujube; decoct). Spring Warmth with fever/cough/body pain/thirst/floating/surging pulse = Xiao Chai Hu Tang plus Gui Zhi. For cough, add Wu Wei Zi. For thirst, remove Ban Xia, add Gua Lou Gen, Ren Shen. For excess pulse/thirst, use Da Chai Hu Tang to purge. For thirst, add Zhi Mu, Shi Gao. Generally, Wen Bing with floating Chi/Cun pulses indicates prior Wind injury compounded by Heat, Wind-Heat combusting. Symptoms: limbs flaccid, fever/sweating, headache/wheezing, thirst/coma, heavy/unresponsive body. Do NOT induce sweating; sweating leads to delirium/irritability, dull eyes. Disease in Shaoyin/Jueyin meridians: use Wei Yu Tang, Ren Shen Bai Du San, Ge Gen Long Dan Tang, Xiao Chai Hu Tang. Severe cases: Gua Lou Ge Gen Tang. Floating pulse/body swelling/sweating: Han Fang Ji Tang. Mistaken sweating: Fang Ji Huang Qi Tang. Four-season Shang Han/Plague, Wind injury with sweat, Wind-Damp, swelling/pain, aversion to cold/dry mouth, afternoon tidal fever, excess pulse: Ren Shen Bai Du San. Summer should be hot but turns cold (early Autumn violent cold), heat binding limbs causing high fever/headache, or Stomach cold causing dysentery/water diarrhea, excess pulse: Purge with Tiao Zhong Tang plus Da Huang (3 qian), Ge Gen, Huang Qin [each 2 qian].
Medical Case
Li Wenhui of Dongyang's wife, Ms. Chen, aged 29, contracted plague in March. On the third day of illness, menstruation began, fever intensified. By days 7-8, condition worsened: chest Qi stabbing pain, unable to lie down. Physicians gave up and left. Summoned at night. Patient sat propped on cotton bags, maid constantly massaged chest. Six pulses were minute, extremely rapid and irregular, resembling shrimp swimming. I asked: "Did premature purging cause Jie Xiong (Chest Binding)?" Owner: "No purging done." I reasoned: Menstruation on day 3 depleted Middle Qi, allowing pathogen to descend. Combined Huang Long Tang, Si Wu Tang, Xiao Xian Xiong Tang into one dose, added ginger/jujube, decocted. Owner asked name. I said: "San He Tang" (Three-Harmonies Decoction). After one dose, symptoms reduced, able to lie down. Second dose: fever subsided, full recovery. Post-recovery, relapse due to overeating porridge. Treated as Internal Injury, regulated with Bu Zhong Yi Qi Tang modifications until cured.
