\r大麻疯\p04-a41a204.bmp\r
陈实功曰∶大麻疯乃天地间异证也，总之骤被暴晒，雾露风雨之气所侵，或房欲
后体虚为风邪所袭，或露卧当风，久卧湿地，总由风湿相乘，气血凝滞，表里不和，
脏腑痞塞，阳火所变，此其根蒂也。其患先从麻木不仁，次发红斑，久则破烂浮肿
无脓，治法初宜发汗，久当培助气血。（《正宗》）
又曰∶皮死麻木不仁，肉死刀割不痛，血死破烂流水，筋死指节脱落，骨死鼻梁崩塌，此为五不治。
又曰∶心受之先损于目，肝受之面发紫泡，脾受之遍身如癣，肺受之眉毛先脱，
肾受之足底先穿，此为五败证，不治。
又曰∶治之当戒房事，浓味动风等物。
《脉诀》曰∶脉洪大者生，沉细者死。
汪省之曰∶大麻疯有三因∶一曰风毒，二曰湿毒，三曰传染。（《理例》）
诀云∶治风先治气，气足风自除，治风先治血，血足风自减。故当分气血二治，
有养气养血之别，故治风之要，莫稳于益气活血为主。
蒋示吉曰∶眉落眼盲，唇翻声噎，皆为难治。所以然者，由邪正交攻，气血沸
腾，而湿痰死血充满于经络之中，热胜则肉腐，故生虫生疮，痛痒麻木也。治法内
通脏腑，外发经络，养荣益卫，补正逐邪，大剂峻补久服，而虫疮痛痒麻木俱自愈矣。（《说约》）
冯鲁瞻曰∶经文治法，有发汗与刺血二法，汗出以泄荣卫之怫热，刺肿以恶血
之留蓄。子和曰∶一汗抵千针，盖以刺血不如汗之周遍也，尤宜助胃气以固根本，实
卫气养荣血以继之。盖原其本，皆由嗜欲
劳动气血，不避邪风冷湿，使湿气与胃气相干而致，是正虚为本，而湿热是标也。虽
曰是风，不可纯作风治。（《锦囊》）
林氏曰∶或问何为疠风？何经受病？何故多死而少生？答曰∶疠者厉也，即阴阳
乖戾之气，俗称大麻风者是也。此气乃天地间阴霾湿热贼风，不正之气，若入肺家，
元气先亏，则鼻窍易于触受，而皮毛腠理因之不密，倘然早起晏眠，宵行露宿，则
毒瓦斯先由鼻入，而阳明独受其邪，盖鼻为肺之窍，而手足阳明经之络，起于鼻之交
中，故人在气交之中，而鼻为肺与肠胃出纳升降之门户，一受风邪，则鼻塞息粗，
打嚏流涕，眉棱酸痛，是其征也。所以毒厉之气，由鼻而直入阳明之络，先则眉痒
而渐脱落，两颧红润浮肿而痒，渐至两臂皮粗毛落，甚而通身肌肤淫淫作痒难忍，其
毒深入血脉之中，则湿热蕴积生虫，侵蚀脏腑，治蛀肌肉，久久精神枯涸，诸虫聚
食，传为痨瘵而死。（《活人录》）
又曰∶或问虽为乖戾之气潜伏脉络之中，若以清散疏解之药治之，自当速愈，何
至生虫，沿蛀皮肤，脏腑败坏，腐烂而死也？答曰∶经云∶大风苛毒，虚邪贼风，皆
阴闭湿热郁蒸之气所化，其性本热，及至阳明，又两阳合明，乃多气多血之府，由
是气温血热，最易生虫，虫多蔓延，尤难缓治。病者先失于不觉不知，继则误于缓
视而毒深，再则不得其法而无效，遂至于败坏而死，非厉风即可以杀人也，患者慎之。
又曰∶此证须在一月之内，速为清散，可保无恙。其精神气血未衰，六脉洪大而
实，或洪数有力者，用汗吐下三法分表里攻逐之，使毒瓦斯不得稽留而速化，继服清
热解毒，凉血补血之剂，禁用辛燥之药，及耗津精血液，而助酷烈之势，但患者必须
清心寡欲，远色忌口，方为有益。
冯鲁瞻曰∶大风病，是受天地间杀物之风，古人谓之疠风者，以其酷裂暴悍耳。
须分在上在下，在上者以醉仙散取臭涎恶血于齿缝中出，在下者以通天再造散取恶
物陈虫于谷道中出，所出虽有上下道路之殊，然皆不外乎手足阳明二经，盖肠胃为
市，无物不受，脾肺二经之腑，脾主肌肉，肺主皮毛，乃腑病及于脏也。治此病者，须
看其疙瘩与疮，若上先见，在上体多者，病在上也；下先见，在下体多者，病在下也；
上下同得者，在上复在下也。胃与大肠，无物不受，此风之入人也，气受之则在上多，
血受之则在下多，气血俱受者甚重，是非医者神手，病者铁心，罕有得愈，若从上
或从下以渐而来者，皆为可治，但人易缓忽，不能断味绝色，则难免再发，再发则终不救矣。
又曰∶风起于八方，应其时则物生，违其时则物杀，凡人中气不足如持虚受物，乃
感受此杀物之气，郁而成湿，久而成热，气浊血污，历传脏腑，生虫溃肌，流行为害，
虫食心则足底穿，膝肿，食肝则眉落，食肺则鼻崩声哑，食肾则耳鸣啾啾，耳弦生
疮，或痹或痛，如针刺状，食身则皮痒如虫行，自头而来为顺风，自足心起者为逆
风，总由湿热之毒，流结而成也。先以再造散下之，稀粥调理，勿妄动作劳，后以
醉仙散取臭涎恶血于齿缝中出，或吐或利，以泄越其邪，面黑渐白而安。
又曰∶大风证者，所因不一，或色欲当风，或醉卧湿地，或乘热脱衣，或汗出
入水，或空心饥饿，山行感山岚瘴气，或劳役奔走，途中冒寒雨阴露，皆由内伤形
体，不知避忌，外感风湿毒瓦斯，入于皮毛血脉肌肉筋骨之间，当时失于驱散，停积
既久，以致荣卫不行，内外熏蒸，内则生虫，外则生疮，脏腑经络皆受患矣。眉毛
先落者，毒在肺；面发紫泡者，毒在肝；脚底先痛或穿者，毒在肾；遍身如癣者，毒
在脾；目先损者，毒在心，此五脏受病之重者也。古人谓大风疾三因五死。三因者∶
一曰风毒，二曰湿毒，三曰传染。五死者∶
一曰皮死，麻木不仁；二曰脉死，血溃成脓；三曰肉死，割切不痛；四曰筋死，手
足缓纵；五曰骨死，鼻梁崩塌；与夫眉落眼盲，唇翻声噎，皆为难治。所以然者，由
邪正交攻，气血沸腾，而湿痰死血充满于经络之中，热胜则肉腐，故生虫生疮，痛
痒麻木也，治法内通脏腑，外发经络，养荣益卫，补正逐邪，大剂峻服久服，而虫
疮痛痒麻木自愈。亦须首尾断酒戒色，忌食发风动气，荤腥盐酱，炙 生冷之物，清心寡欲，方保无虞。
又曰∶疠疡所患，非止一脏，然其气血无有弗伤，兼证无有弗杂，况积岁而发
现于外，须分经络之上下，病势之虚实，不可概施攻毒之药。当先助胃壮气，使根本
坚固而后治其疮，盖病有变有类之不同，而治法有汗有下，有砭刺攻补之不一，兼证
当审轻重，变证当察后先，类证当详真伪，而汗下砭刺攻补之法，又当量其人之虚实，
究其病之源委而施治焉。盖虚者，正气虚也；实者，病气实也。再造散治其病在阴
者，用皂角刺直达病所，出风毒于荣血中，肝主血，恶血留止，属肝也；且虫亦生于
厥阴，风木所化，用此以治其脏气杀虫为主，白丑者专入胃与大肠，既走下焦血分，
复去气中湿热，追虫取积，从大小便而利出之，郁金者因性轻扬，善治郁遏气血之
凝滞，因味苦辛，善消阳毒积热之亢炎，以大黄引入肠胃荣血之分，利出瘀血虫物。醉
仙散治其病在阳者，用鼠粘子解散阳明风毒，遍身恶疮，胡麻逐诸风润皮肤，蒺藜
散恶血而清胃，通鼻气而祛风，防风为诸风之总司，栝蒌根解烦热之要领，枸杞润
肾燥而祛风，蔓荆散风淫而明目，苦参专攻湿热，扫除溃疡，以祛赤癞落眉之毒，八
者祛风散毒，上下内外周而至矣。
又曰∶风有三十六证，而厉风为最酷，感之难免于死者，以其更多不守禁忌也。经
曰∶脉风盛为疠，疠者恶也。脉主血，血热而杀厉之气袭之，则血脉凝泣，卫气不
行，其气不清，鼻为呼吸之所要，宗气由之出入也。今营运之气不能上升为用，故鼻柱腐坏，肌肉溃疡也。
又曰∶一贫妇因无膏粱浓味，故服醉仙散外，又服加减四物汤百余剂，半年之
间，月经行而风证亦愈，故贵薄滋味也。
《风论》曰∶风气与太阳俱入行诸俞，散于分肉之间，与卫气相干，其道不利，故
使肌肉愤 而有疡，卫气有所凝而不行，故其肉有不行也。疠者，有营气热 ，其气
不清，故使鼻柱坏而色败，皮肤疡溃，风寒客于脉而不去，名曰疠风，或名曰寒热。
《长刺节论》曰∶病大风骨节重，须眉堕，名曰大风，刺肌肉为故汗出百日，刺
骨髓汗出百日，凡二百日须眉生而止针。疠风者，素刺其肿上已，刺以锐针，针其处，
按出其恶气，肿尽乃止，常食方食，无食他食。
《脉要精微论》曰∶脉风成为疠。
张景岳曰∶疠风即大风也，又谓之癞风，俗又名为大麻风。此病虽名为风，而
实非外感之风也，实以天地间阴疠浊恶之邪，或受风木之化，而风热化虫，或受湿
毒于皮毛，而后及营卫，或犯不洁，或因传染，皆得生虫，盖虫者厥阴主之，厥阴
为风木，主生五虫也。虫之生也，初不为意，而渐久渐多，遂致不可解救，诚最恶
最危最丑证也。又《千金》云∶自作不仁极恶之孽也，所以最为难治。观孙真人云∶
尝治数百人，终无一人免于死者，盖无一人能守禁忌故耳，唯一妇人病愈后，又服
加减四物汤百余剂，半年之上，方得经行，十分痊愈。又丹溪治五人，亦唯一妇人得
免，以其贫甚且寡，无物可吃也。外三四人者，越二三年皆复作而死。由此观之，可
见此证非得出奇秘方，鲜能取效，故予逢此证，不敢强以为知而妄施治疗，亦不敢
强言治法，以惑后人，至若古人论治之法，亦甚详悉，用之得宜，虽病根未必可拔，而
延保余年，夭枉自亦可免，由是求遍诸说，
则惟薛立斋《疠疡机要》论列已全，今择其要并诸论之得理者，以为证治纲领。
《耆婆恶病论》曰∶疾风有四百四种，总而言之，不出五种，即是五风∶一曰黄
风，二曰青风，三曰白风，四曰赤风，五曰黑风，其风合五脏，故曰五风。五风生
五虫，黄风生黄虫，青风生青虫，白风生白虫，赤风生赤虫，黑风生黑虫，食人五
脏。若食人脾，语变声散；食人肝，眉睫堕落；食人心，遍身生疮；食人肺，鼻柱
崩倒，鼻生息肉；食人肾，耳鸣啾啾，或如车行雷鼓之声；若食人皮，皮肤顽痹；食
人筋，肢节堕落。五风合五脏，虫生致多，入于骨髓，往来无碍坏于人身，名曰疾风。
疾风者，是疠风之根本也。病之初起，或如针锥所刺，名曰刺风；或如虫走，名曰
游风；遍身掣动，名曰 风；不觉痛痒，名曰顽风；肉起如桃李小枣核，从头面起者，
名曰顺风；从两脚起者，名曰逆风；如连钱团圆，赤白青乌斑驳，名曰KT 风。或遍
体生疮，或如鱼鳞，或如榆荚，或痒或痛，黄汁流出，肢节坏烂，为脓为血，或不痛
不痒，或起或灭，青黄赤白黑，变易不定，病起之由，皆因冷热不调，流于五脏，通
彻骨髓，用力过度，饮食杂秽，房室不节，虚劳转极，汗流遍体，因兹积热于五脏，致
生多虫，食人五脏，骨髓、皮肉、筋节久久败坏，名曰疠风，惟见黑虫者，最为难
治，人得此疾，速宜弃家室财物，离妻外家，入山静养，治无有不瘥。
徐东皋曰∶经云∶汗之则疮已，况癞之为风，尤疮之最恶者，故曰疠风。诸疮
热久，热则生风，且疠风尤染肃杀之气而成者，若非汗法，何以去其风毒？所以汗
之一法，乃治疠之最要者，其余诸方，次第用之。
又曰∶凡患人身上痒甚，盖以风邪气郁，血不荣敷而然，宜四物汤加黄芩、白芷，调浮萍末服，发汗自愈。
张子和曰∶一汗抵千针，盖砭血不如
发汗之周遍也，然发汗即出血，出血即发汗，二者一律。
沈紫亮曰∶夫人之生也，禀天地之阴阳，父精母血而成形体，外毫窍，五内腑，
周身百骸，十四经络，合于天地同参。故曰∶天乃一大天，人乃一小天，然天有晴
明昧晦，风寒暑湿燥火之气。而人亦有气血盛衰，喜怒哀乐之情，是故君子调饮食
而慎房劳，节喜怒而善摄养，无七情之内伤，避风寒，畏暑湿，忌燥火，无六淫之
外感，则病无从而生，是无夭折之患。《上古天真论》曰∶上工治未病。愚意非工之
能，乃人自治耳。如稍不知节，纵欲纵食，任喜任怒，致七情偏胜，气血不和，六淫
易入，百病生焉。即如大麻疯一证，大小轻重，计有三十六种，证最酷烈，最为剧
恶，而感之者，变形易质，眉发脱而手足痿，肌肉溃烂，十指堕落，脓秽淋漓，臭
恶难闻，人皆怨而避之，可不慎哉！前之先哲，论此证之由有五∶一曰风水阴阳所
损，二曰源流传染所因，三曰气秽毒注所犯，四曰保养失度所致，五曰感冒积郁所
生，此言其大略耳。然麻疯之始由，各有不同，有壮年而发者，有十四五岁而发者，
有四五岁而发者，所感有殊，其壮年而发者，因不能节欲，致丧肾元，精液枯涸，腠
理不密，易感寒湿之邪，积久不去，况水衰不能生木，则肝虚易动而风生，且风数
动易变，与湿相搏，遂化为热，又不能驱之补之，则根坚蒂固，日甚一日，风引湿
热之毒攻之肌肉皮毛，壅遏于肌肉经络之间，则气血不行，初或头面手足有一点麻
木不仁，如病者之家，明其为恶候，即延医而调治之，明察其得病之浅深，风湿之
陈实功说：大麻疯是天地间罕见的病症，总之是由于突然遭受暴晒，或雾露风雨之气侵袭，或者在房事之后身体虚弱被风邪袭击，或者露天睡觉对着风，长期睡在潮湿的地方，总归是由风湿相互侵犯，导致气血凝滞，表里不和，脏腑痞塞，由阳火变化而成，这是它的根本原因。这种病起初先从麻木不仁开始，接着出现红斑，时间久了则皮肤破烂浮肿但没有脓液，治疗初期适宜发汗，久病则应当培补助益气血。（《外科正宗》）
又说：皮肤死则麻木不仁，肌肉死则刀割不痛，血液死则破烂流水，筋腱死则指节脱落，骨骼死则鼻梁崩塌，这称为五不治之症。
又说：心受病则先损害眼睛，肝受病则面部出现紫泡，脾受病则全身像癣一样，肺受病则眉毛先脱落，肾受病则脚底先穿孔，这称为五败证，无法治愈。
又说：治疗时应当戒除房事，以及浓味、动风等食物。
《脉诀》说：脉象洪大的预后良好（生），脉象沉细的预后不良（死）。
汪省之说：大麻疯有三种病因：一是风毒，二是湿毒，三是传染。（《理例》）
口诀说：治风先治气，气足风自除；治风先治血，血足风自减。因此应当分气血两方面治疗，有养气和养血的区别，所以治疗风病的关键，莫过于以益气活血为主。
蒋示吉说：眉毛脱落、眼睛失明、嘴唇翻卷、声音嘶哑吞咽困难，都难以治疗。之所以这样，是因为邪正交争，气血沸腾，而湿痰和死血充满在经络之中，热盛则肌肉腐败，所以生虫生疮，产生疼痛、瘙痒、麻木等症状。治疗方法应内通脏腑，外发经络，滋养荣卫，补益正气驱逐邪气，使用大剂量的峻补药物长期服用，那么虫疮、疼痛、瘙痒、麻木都会自愈。（《疡医说约》）
冯鲁瞻说：经文中的治疗方法，有发汗和刺血两种方法，出汗是为了泄出营卫之间的郁热，刺破肿胀部位是为了排出留蓄的恶血。张子和说：一次发汗抵得上千次针刺，因为刺血不如发汗那样周身遍达，尤其应当助益胃气以巩固根本，充实卫气、滋养荣血来接续其后。推究其本源，都是由于嗜欲过度、劳累导致气血受损，又不躲避邪风冷湿，使湿气与胃气相干扰而导致，这是正气虚为本，湿热为标。虽然说是风病，不可以单纯按风病来治疗。（《疡医锦囊》）
林氏说：有人问什么是疠风？哪条经脉受病？为什么多死少生？回答说：疠就是厉，即阴阳乖戾之气，俗称大麻风的就是这种气。这种气是天地间阴霾湿热贼风，不正之气，如果进入肺家，元气先亏，那么鼻窍容易受到触动，皮毛腠理因此不紧密，如果早起晚睡，夜间行走露天宿睡，那么毒瓦斯先从鼻子进入，阳明经独自承受这个邪气，大概因为鼻子是肺的窍道，而手足阳明经的络脉，起于鼻翼旁的迎香穴附近，所以人在气交之中，鼻子是肺与肠胃出纳升降的门户，一旦受到风邪，就会鼻塞呼吸粗重，打喷嚏流鼻涕，眉棱骨酸痛，这是征象。所以毒厉之气，从鼻子直接入阳明之络，起初眉毛痒而逐渐脱落，两颧红润浮肿且痒，逐渐到两臂皮肤粗糙毛发脱落，甚至全身肌肤瘙痒难忍，其毒深入血脉之中，则湿热蕴积生虫，侵蚀脏腑，蛀蚀肌肉，久而久之精神枯涸，各种虫子聚集进食，传播成为痨瘵而死。（《活人录》）
又说：有人问虽然是乖戾之气潜伏在脉络之中，如果用清散疏解的药物来治疗，自然应当迅速痊愈，怎么会生虫，沿着蛀蚀皮肤，脏腑败坏，腐烂而死呢？回答说：经文说：大风苛毒，虚邪贼风，都是由阴闭湿热郁蒸之气所化，其性质本热，等到传入阳明，又是两阳合明，乃是多气多血的府库，因此气温血热，最容易生虫，虫子多了蔓延开来，尤其难以缓慢治疗。患者起初失去警惕不知不觉，接着误于轻视而毒邪深重，再则不得法而无效，于是到了败坏而死的地步，并不是厉风就可以杀人，患者要谨慎。
又说：此证必须在一个月之内，迅速进行清散治疗，可以保全无恙。其精神气血未衰，六脉洪大而实，或洪数有力的，用汗、吐、下三法分别攻逐表里的毒邪，使毒瓦斯不得稽留而迅速化解，继服清热解毒、凉血补血的药剂，禁用辛燥的药物，以及耗伤津精血液，而助长酷烈之势，但患者必须清心寡欲，远离女色忌口，才有益处。
冯鲁瞻说：大风病，是受天地间杀物之风，古人称之为疠风的，是因为它残酷暴悍罢了。必须分在上部和下部，在上部的用醉仙散取出齿缝中的臭涎恶血，在下部的用通天再造散取出谷道中的恶物陈虫，所出的途径虽然有上下道路的不同，然而都不外乎手足阳明二经，大概肠胃为市，无物不受，脾肺二经所属的腑，脾主肌肉，肺主皮毛，这是腑病波及于脏。治疗此病的人，必须看其疙瘩与疮，如果上面先出现，在上半身多的，病在上部；下面先出现，在下半身多的，病在下部；上下同时得到的，是上部又涉及下部。胃与大肠，无物不受，此风侵入人体，气受病则在上部多，血受病则在下部多，气血都受病的很重，如果不是医生手法高明，病人意志坚定，很少有能治愈的，如果是从上或从下逐渐而来的，都为可治，但人容易疏忽大意，不能断绝滋味女色，则难免复发，再发则最终无法救治了。
又说：风起源于八方，顺应时节则万物生长，违背时节则万物死亡，凡人中气不足如同手持空虚之物接受重物，乃感受这种杀物之气，郁结而成湿，久了变成热，气浊血污，流传传遍脏腑，生虫溃烂肌肉，流行为害，虫子吃心则脚底穿孔，膝盖肿，吃肝则眉毛脱落，吃肺则鼻梁崩塌声音嘶哑，吃肾则耳鸣啾啾，耳弦生疮，或者麻痹或者疼痛，如针刺状，吃身体则皮肤痒如虫行，从头而来为顺风，从脚心起者为逆风，总归是由湿热之毒，流结而成。先用再造散泻下，用稀粥调理，不要妄动劳累，后用醉仙散取出齿缝中的臭涎恶血，或者呕吐或者腹泻，以宣泄邪气，面色由黑渐白而安愈。
又说：大风证的成因不一，或者房事当风，或者醉酒睡在湿地，或者乘热脱衣，或者出汗后入水，或者空腹饥饿，在山中行走感受山岚瘴气，或者劳役奔走，途中冒寒雨阴露，都是由内伤形体，不知道避忌，外感风湿毒瓦斯，进入皮毛血脉肌肉筋骨之间，当时失于驱散，停积既久，以致营卫不行，内外熏蒸，内则生虫，外则生疮，脏腑经络都受害了。眉毛先落的，毒在肺；面部发紫泡的，毒在肝；脚底先痛或穿孔的，毒在肾；全身像癣一样的，毒在脾；眼睛先损害的，毒在心，这是五脏受病的重症。古人说大风疾有三因五死。三因是：一是风毒，二是湿毒，三是传染。五死是：一是皮死，麻木不仁；二是脉死，血溃成脓；三是肉死，割切不痛；四是筋死，手足缓纵；五是骨死，鼻梁崩塌；以及眉毛脱落眼睛失明，嘴唇翻卷声音嘶哑，都难以治疗。之所以这样，是因为邪正交争，气血沸腾，而湿痰死血充满在经络之中，热盛则肌肉腐败，所以生虫生疮，疼痛瘙痒麻木，治疗方法内通脏腑，外发经络，滋养荣卫，补益正气驱逐邪气，大剂量峻猛服用长期服用，那么虫疮疼痛瘙痒麻木自愈。也必须从头到尾断酒戒色，忌食发风动气、荤腥盐酱、炙烤生冷之物，清心寡欲，才能保全无忧。
又说：疠疡所患，不止一脏，然而其气血没有不受伤的，兼证没有不混杂的，何况积累岁月而在外部显现，必须分经络的上下，病势的虚实，不可一概施用攻毒的药物。应当先助胃壮气，使根本坚固而后治疗其疮，大概病有变有类之不同，而治疗方法有汗有下，有砭刺攻补之不一，兼证应当审察轻重，变证应当察辨先后，类证应当详辨真伪，而汗下砭刺攻补的方法，又应当衡量人的虚实，探究病的源委而施治。大概虚者，是正气虚；实者，是病气实。再造散治疗病在阴的，用皂角刺直达病所，将风毒从营血中引出，肝主血，恶血留止，属于肝；而且虫子也生于厥阴，风木所化，用此药治疗其脏气杀虫为主，白丑专入胃与大肠，既走下焦血分，又去除气中湿热，追虫取积，从大小便利出。郁金因为性质轻扬，善于治疗郁遏气血的凝滞，因为味道苦辛，善于消除阳毒积热的亢炎，以大黄引入肠胃荣血之分，利出瘀血虫物。醉仙散治疗病在阳的，用鼠粘子解散阳明风毒，遍身恶疮，胡麻驱逐诸风润皮肤，蒺藜散恶血而清胃，通鼻气而祛风，防风为诸风之总司，栝蒌根解烦热之要领，枸杞润肾燥而祛风，蔓荆散风淫而明目，苦参专攻湿热，扫除溃疡，以祛除赤癞落眉之毒，八种药祛风散毒，上下内外周全而至。
又说：风有三十六种证候，而厉风最为残酷，感染后难免死亡的，是因为更多不守禁忌。经文说：脉风盛为疠，疠就是恶。脉主血，血热而杀厉之气袭击它，则血脉凝涩，卫气不行，其气不清，鼻子是呼吸的要道，宗气由此出入。现在营运之气不能上升为用，所以鼻柱腐坏，肌肉溃疡。
又说：一个贫穷的妇人因为没有膏粱厚味，所以在服用醉仙散之外，又服用加减四物汤百余剂，半年之间，月经通行而风证也痊愈，所以贵在淡薄滋味。
《风论》说：风气与太阳经一起进入，运行诸俞穴，散布于分肉之间，与卫气相干扰，其道不利，所以使肌肉愤满而有疡，卫气有所凝而不行，所以其肉有不行。疠风，有营气热，其气不清，所以使鼻柱坏而色败，皮肤疡溃，风寒客于脉而不去，名叫疠风，或者名叫寒热。
《长刺节论》说：病大风骨节重，须眉堕落，名叫大风，刺肌肉作为目标出汗百日，刺骨髓出汗百日，凡二百日须眉生出而停止针刺。疠风者，素来刺其肿上已，刺用锐针，针其处，按压出其恶气，肿尽乃止，常食方食，不吃其他食物。
《脉要精微论》说：脉风成为疠。
张景岳说：疠风即大风，又叫做癞风，俗名又叫做大麻风。此病虽然名为风，而实际上不是外感的风，实在是天地间阴疠浊恶之邪，或者受风木之化，而风热化虫，或者受湿毒于皮毛，而后及于营卫，或者犯不洁，或者因传染，都能生虫，大概虫子是厥阴主之，厥阴为风木，主生五虫。虫的产生，起初不在意，而渐渐久渐渐多，遂致不可解救，诚然是最恶最危最丑的证候。又《千金方》说：自作不仁极恶之孽，所以最为难治。看孙真人说：曾经治疗数百人，终无一人免于死的，大概是没有一人能守禁忌的缘故，只有一位妇人病愈后，又服用加减四物汤百余剂，半年以上，方才得月经通行，十分痊愈。又丹溪治疗五人，也只有一位妇人得免，因为她很穷且寡居，没有什么可吃的。另外三四个人，过两三年都复发而死。由此看来，可见此证非得出奇秘方，很少能取效，所以我遇到此证，不敢强以为知而妄施治疗，也不敢强言治法，以迷惑后人，至于古人论治的方法，也很详细，用得适宜，虽然病根未必可拔，而延保余年，夭折枉死自然也可避免，由此求遍诸说，则只有薛立斋《疠疡机要》论述已全，今择其要点并诸论中得理的，作为证治纲领。
《耆婆恶病论》说：疾风有四百多种，总而言之，不出五种，即是五风：一是黄风，二是青风，三是白风，四是赤风，五是黑风，其风合五脏，所以叫五风。五风生五虫，黄风生黄虫，青风生青虫，白风生白虫，赤风生赤虫，黑风生黑虫，吃人五脏。如果吃人脾，言语改变声音散乱；吃人肝，眉毛睫毛堕落；吃人心，全身生疮；吃人肺，鼻柱崩倒，鼻生息肉；吃人肾，耳鸣啾啾，或者如车行雷鼓之声；如果吃人皮，皮肤顽痹；吃人筋，肢节堕落。五风合五脏，虫生导致很多，进入骨髓，往来无阻破坏人身，名叫疾风。疾风，是疠风的根本。病之初起，或者如针锥所刺，名叫刺风；或者如虫走，名叫游风；全身掣动，名叫掣风；不觉痛痒，名叫顽风；肉起如桃李小枣核，从头面起的，名叫顺风；从两脚起的，名叫逆风；如连钱团圆，赤白青乌斑驳，名叫KT风。或者遍体生疮，或者如鱼鳞，或者如榆荚，或者痒或者痛，黄汁流出，肢节坏烂，为脓为血，或者不痛不痒，或者起或者灭，青黄赤白黑，变易不定，病起的原因，都是因为冷热不调，流于五脏，通彻骨髓，用力过度，饮食杂秽，房室不节，虚劳转极，汗流遍体，因此积热于五脏，导致生多虫，吃人五脏，骨髓、皮肉、筋节久久败坏，名叫疠风，只见黑虫的，最为难治，人得此疾，速宜弃家室财物，离妻外家，入山静养，治疗没有不痊愈的。
徐东皋说：经文说：汗之则疮已，何况癞之为风，尤疮之最恶者，所以叫疠风。诸疮热久，热则生风，且疠风尤染肃杀之气而成的，如果不是汗法，何以去除其风毒？所以汗之一法，乃是治疠的最重要的，其余诸方，次第用之。
又说：凡是患病人身上一痒得很厉害，大概是因为风邪气郁，血不荣敷而然，宜用四物汤加黄芩、白芷，调浮萍末服用，发汗自愈。
张子和说：一次发汗抵得上千次针刺，大概砭血不如发汗那样周遍，然而发汗即出血，出血即发汗，二者一律。
沈紫亮说：人之生也，禀受天地之阴阳，父精母血而成形体，外毫窍，五内腑，周身百骸，十四经络，合于天地同参。所以说：天乃一大天，人乃一小天，然而天有晴明晦暗，风寒暑湿燥火之气。而人也有气血盛衰，喜怒哀乐之情，所以君子调饮食而慎房劳，节喜怒而善摄养，无七情之内伤，避风寒，畏暑湿，忌燥火，无六淫之外感，则病无从而生，是无夭折之患。《上古天真论》说：上工治未病。我的意思不是医生的能力，而是人自治罢了。如果稍微不知道节制，纵欲纵食，任喜任怒，致七情偏胜，气血不和，六淫易入，百病生焉。就像大麻疯一证，大小轻重，计有三十六种，证候最酷烈，最为剧恶，而感染的人，变形易质，眉毛头发脱落而手足痿废，肌肉溃烂，十指堕落，脓秽淋漓，臭恶难闻，人都怨恨而避开，能不谨慎吗！之前的先哲，论述此证的原因有五种：一是风水阴阳所损，二是源流传染所因，三是气秽毒注所犯，四是保养失度所致，五是感冒积郁所生，这是说其大略罢了。然而麻疯的开始由来，各有不同，有壮年而发的，有十四五岁而发的，有四五岁而发的，所感有殊，其壮年而发的，因为不能节欲，导致丧失肾元，精液枯涸，腠理不密，易感寒湿之邪，积久不去，况且水衰不能生木，则肝虚易动而风生，且风数动易变，与湿相搏，遂化为热，又不能驱之补之，则根坚蒂固，日甚一日，风引湿热之毒攻之肌肉皮毛，壅遏于肌肉经络之间，则气血不行，起初或者头面手足有一点麻木不仁，如果患者的家人，明白其为恶候，立即延请医生调治，明察其得病的浅深，风湿的……
Leprosy (Dama Feng)
Chen Shigong stated: Leprosy (Dama Feng, a severe form of leprosy characterized by nodules and deformities) is a rare condition in the world. In summary, it is caused by sudden exposure to intense sunlight, invasion by mist, dew, wind, and rain, or attack by Wind Pathogens after sexual intercourse when the body is deficient. It may also result from sleeping outdoors facing the wind or lying on damp ground for a long time. Ultimately, it stems from the mutual assault of Wind and Dampness, leading to stagnation of Qi and Blood, disharmony between the exterior and interior, obstruction of the Zang-Fu organs, and transformation by Yang Fire. This constitutes its root cause. The disease initially presents with numbness and insensitivity, followed by the appearance of red macules. Over time, the skin becomes ulcerated and edematous without pus. In the early stage, treatment should favor diaphoresis (inducing sweating). For chronic cases, tonifying and supporting Qi and Blood is necessary. (*Waike Zhengzong*)
He further stated: If the skin dies, there is numbness and insensitivity; if the flesh dies, cutting causes no pain; if the blood dies, ulcers weep fluid; if the tendons die, finger joints detach; if the bones die, the nasal bridge collapses. These are known as the "Five Untreatable Conditions."
He also stated: If the Heart is affected, the eyes are damaged first; if the Liver is affected, purple blisters appear on the face; if the Spleen is affected, the whole body resembles tinea; if the Lungs are affected, eyebrows fall out first; if the Kidneys are affected, the soles of the feet perforate first. These are known as the "Five Defeat Syndromes," which are untreatable.
He further stated: Treatment requires abstaining from sexual activity and consuming rich flavors or foods that stir Wind.
*Mai Jue* (Pulse Classic) states: A洪大 (Hongda, surging and large) pulse indicates survival, while a 沉细 (Chenxi, deep and fine) pulse indicates death.
Wang Shengzhi stated: Leprosy has three etiologies: one is Wind Toxin, two is Dampness Toxin, and three is contagion. (*Li Li*)
A maxim states: To treat Wind, first regulate Qi; when Qi is sufficient, Wind naturally dissipates. To treat Wind, first nourish Blood; when Blood is sufficient, Wind naturally diminishes. Therefore, treatment should distinguish between Qi and Blood, with specific methods for nourishing Qi and nourishing Blood. Thus, the key to treating Wind lies primarily in benefiting Qi and invigorating Blood.
Jiang Shiji stated: Loss of eyebrows, blindness, everted lips, hoarseness, and dysphagia are all difficult to treat. The reason is that pathogenic factors and healthy Qi contend, causing Qi and Blood to boil, while Phlegm-Dampness and dead Blood fill the meridians. Excessive Heat rots the flesh, leading to the generation of parasites and sores, resulting in pain, itching, and numbness. The treatment method involves unblocking the Zang-Fu internally, venting the meridians externally, nourishing Ying and Wei, tonifying healthy Qi to expel pathogens. Using large doses of potent tonics taken over a long period will allow the parasites, sores, pain, itching, and numbness to heal spontaneously. (*Yangyi Shuyue*)
Feng Luzhan stated: The classic texts mention two treatment methods: diaphoresis and bloodletting. Sweating releases the stagnant heat within Ying and Wei; puncturing swellings expels retained evil blood. Zhang Zihe said: One instance of sweating equals a thousand needle pricks, because bloodletting is not as comprehensive as sweating. It is especially important to support Stomach Qi to consolidate the root, and to solidify Wei Qi and nourish Ying Blood subsequently. Tracing the origin, this arises from excessive desires and labor damaging Qi and Blood, combined with failure to avoid pathogenic Wind, Cold, and Dampness. This causes Dampness to interfere with Stomach Qi. Thus, Healthy Qi deficiency is the root, and Damp-Heat is the branch. Although termed a Wind disease, it cannot be treated solely as Wind. (*Yangyi Jinnang*)
Lin Shi stated: Someone asked: What is Li Feng? Which meridians are involved? Why is mortality high and survival low? The answer is: "Li" means fierce/malignant. It refers to the Qi of Yin-Yang discordance, commonly known as Leprosy. This Qi is the shady, damp-heat, thieving Wind, and irregular Qi of the world. If it enters the Lung system, Yuan Qi is already deficient, making the nasal orifices susceptible. Consequently, the skin pores and interstices become loose. If one rises early, sleeps late, travels at night, or sleeps outdoors, the toxic vapors enter through the nose first. The Yangming Meridians alone bear this pathogen. Since the nose is the orifice of the Lungs, and the collateral vessels of the Hand and Foot Yangming Meridians originate near the intersection of the nose, when a person is amidst the interaction of Qi, the nose serves as the portal for respiration and the ascending/descending functions of the Lungs and intestines/stomach. Upon Wind Pathogen invasion, symptoms include nasal congestion, coarse breathing, sneezing, rhinorrhea, and soreness/aching in the brow ridge. Thus, the malignant Qi enters the Yangming collaterals directly via the nose. Initially, eyebrows itch and gradually fall out; the zygomatic areas become red, swollen, and itchy. Gradually, the skin on both arms becomes rough with hair loss. Eventually, the entire body suffers unbearable itching. When the toxin penetrates deeply into the blood vessels, Damp-Heat accumulates and generates parasites, eroding the Zang-Fu organs and corroding muscles. Over time, spirit and essence wither away, parasites gather to feed, transmitting into consumption (Lao Zhai), leading to death. (*Huo Ren Lu*)
He further stated: Someone asked: Although malignant Qi lurks in the collaterals, why does treatment with clearing, dispersing, and resolving herbs fail to cure quickly, instead leading to parasite generation, skin corrosion, organ failure, and death by rotting? The answer is: The classics state that Great Wind and harsh toxins, false evils and thieving winds, are all transformed from Yin-closed, Damp-Heat stagnant Qi. Their nature is inherently Hot. Upon reaching Yangming, which represents the convergence of two Yangs and is a reservoir of abundant Qi and Blood, the warmth of Qi and heat of Blood easily generate parasites. As parasites multiply and spread, slow treatment is ineffective. Patients initially lack awareness, then neglect the condition allowing the toxin to deepen, and finally receive improper treatment, leading to deterioration and death. It is not merely that Malignant Wind kills; patients must be cautious.
He further stated: This condition must be cleared and dispersed rapidly within one month to ensure safety. If spirit, Qi, and Blood are not yet depleted, and the six pulses are Hongda (surging-large) and solid, or Hongshu (surging-rapid) and forceful, use the three methods of Diaphoresis, Emesis, and Purging to attack the exterior and interior respectively, preventing toxin retention and facilitating rapid resolution. Subsequently, administer formulas that clear Heat, resolve toxicity, cool Blood, and nourish Blood. Strictly avoid acrid-dry drugs and substances that consume fluids, essence, and blood, which would exacerbate the fierce pathogen. Patients must cultivate a pure heart, reduce desires, avoid sexual activity, and observe dietary restrictions to benefit.
Feng Luzhan stated: Da Feng Bing (Great Wind Disease) results from inhaling the "killing wind" of the world, anciently called Li Feng due to its cruelty and ferocity. It must be differentiated as upper or lower. For upper manifestations, Zuixian San is used to extract foul saliva and evil blood from the teeth gaps. For lower manifestations, Tongtian Zaizao San is used to expel evil matter and old parasites via the anus. Although the exit routes differ (upper vs. lower), both involve the Hand and Foot Yangming Meridians. The intestines and stomach are like a market, accepting everything. The Spleen governs muscle, and the Lungs govern skin/hair; thus, Fu organ disease affects the Zang organs. Treating this requires observing nodules and sores: if appearing first on the upper body, the disease is upper; if lower, the disease is lower; if simultaneous, it involves both. Stomach and Large Intestine accept all; if Qi is affected, symptoms dominate above; if Blood is affected, symptoms dominate below; if both are affected, it is severe. Without a divine physician's skill and an iron-willed patient, recovery is rare. If onset is gradual from top or bottom, it is treatable. However, if patients are negligent and cannot abstain from flavors and sex, relapse is inevitable, leading to ultimate incurability.
He further stated: Wind originates from eight directions; it promotes growth when in season but kills when out of season. People with insufficient Middle Qi are vulnerable to this killing Qi, which condenses into Dampness, then Heat. Turbid Qi and filthy Blood circulate through the Zang-Fu, generating parasites and ulcerating muscles. Parasites eating the Heart cause foot perforation and knee swelling; eating the Liver causes eyebrow loss; eating the Lungs cause nasal collapse and hoarseness; eating the Kidneys cause tinnitus (buzzing/rumbling) and ear sores; affecting the body causes skin itching like insects crawling. Onset from the head is "Shun Feng" (Smooth Wind); onset from the soles is "Ni Feng" (Reverse Wind). Both stem from Damp-Heat toxin accumulation. First, use Zaizao San to purge, followed by thin rice gruel for regulation, avoiding exertion. Then, use Zuixian San to extract foul saliva and evil blood via vomiting or purging to vent the pathogen. The complexion turns from black to white, and peace is restored.
He further stated: Causes of Da Feng Zheng vary: sexual activity in the wind, drunken sleep on damp ground, undressing while hot, entering water while sweating, fasting hunger, mountain miasma, laborious running, or exposure to cold rain/dew. All result from internal injury to the body, failure to avoid taboos, and external contraction of Wind-Damp-Toxin Vapors entering skin, blood vessels, muscles, and bones. Failure to disperse them initially leads to stagnation, blocking Ying and Wei, causing internal/external steaming, internal parasite generation, and external sores, affecting all Zang-Fu and meridians. Eyebrow loss indicates Lung toxin; facial purple blisters indicate Liver toxin; foot pain/perforation indicates Kidney toxin; body-wide tinea-like rash indicates Spleen toxin; eye damage indicates Heart toxin. These are severe Zang diseases. Ancients spoke of Three Causes and Five Deaths. Three Causes: Wind Toxin, Dampness Toxin, Contagion. Five Deaths: 1. Skin death (numbness); 2. Pulse death (blood suppurates); 3. Flesh death (cutting causes no pain); 4. Tendon death (limbs flaccid); 5. Bone death (nasal collapse). Plus eyebrow loss, blindness, lip eversion, and dysphagia are difficult to treat. Reason: Pathogen vs. Healthy Qi contention, boiling Qi/Blood, Phlegm-Damp/Dead Blood in meridians, Heat rotting flesh, generating parasites/sores/pain/itch/numbness. Treatment: Unblock Zang-Fu internally, vent meridians externally, nourish Ying/Wei, tonify healthy Qi/expel pathogen. Use large doses of strong tonics long-term. Must abstain from alcohol and sex, avoid Wind-stirring/spicy/salty/fried/cold foods, cultivate purity and reduce desires to ensure safety.
He further stated: Li Yang lesions affect more than one Zang, inevitably injuring Qi and Blood, with mixed complications. Chronic external manifestations require differentiating meridian location (upper/lower) and syndrome nature (deficiency/excess). Do not indiscriminately use toxic-expelling drugs. First, strengthen Stomach and boost Qi to secure the root before treating sores. Diseases vary in change and category; treatments vary in diaphoresis, purging, scarification, tonification, and draining. Complications require assessing severity; changes require judging sequence; similar syndromes require distinguishing true/false. Diaphoretic, purgative, scarification, tonifying, and draining methods must be tailored to the patient's deficiency/excess and the disease's origin. Deficiency refers to Healthy Qi deficiency; Excess refers to Pathogenic Qi excess. Zaizao San treats Yin-location diseases using Gleditsiae Spina (Zaojiaoci) to reach the lesion, expelling Wind Toxin from Ying-Blood. Liver governs Blood; stagnant evil blood belongs to Liver. Parasites also arise in Jueyin (Wind-Wood). This formula targets the Zang Qi to kill parasites. Bai Chou (Semen Canavaliae) enters Stomach/Large Intestine, moves Lower Jiao Blood, removes Qi-level Damp-Heat, drives out parasites/accumulations via stool/urine. Yujin (Curcumae Radix) is light and ascending, resolving Qi-Blood stagnation; bitter/acrid, clearing Yang-Toxin Heat. Combined with Dahuang (Rhei Radix et Rhizoma) to guide into Gut Ying-Blood, purging瘀血 (stasis) and parasites. Zuixian San treats Yang-location diseases using Niubangzi (Arctii Fructus) to resolve Yangming Wind Toxin and general sores; Huma (Sesami Fructus) dispels Wind and moistens skin; Jili (Tribuli Fructus) scatters evil Blood, clears Stomach, opens nose, expels Wind; Fangfeng (Saposhnikoviae Radix) commands all Winds; Gualougen (Trichosanthis Radix) resolves烦热 (vexing heat); Gouqi (Lycii Fructus) moistens Kidney dryness and expels Wind; Manjingzi (Vitalae Fructus) disperses Wind-Excess and brightens eyes; Kushen (Sophorae Flavescentis Radix) attacks Damp-Heat, cleanses ulcers, removes toxin causing erythema/nodules and eyebrow loss. These eight herbs scatter Wind and resolve Toxin, covering upper/lower and interior/exterior comprehensively.
He further stated: There are 36 Wind syndromes, with Li Feng being the most cruel. Death is common due to non-compliance with taboos. Classics say: "Pulse Wind abundance creates Li; Li means evil." Pulse governs Blood; Blood Heat attacked by Killing/Malignant Qi causes Blood vessel coagulation/stagnation and Wei Qi stagnation. Qi becomes turbid. Nose is vital for respiration and Zong Qi passage. Current circulating Qi fails to ascend, causing nasal pillar decay and muscle ulceration.
He further stated: A poor woman, lacking rich food, took Zuixian San plus Jiajian Siwu Tang (Modified Four Substance Decoction) for over 100 doses. Within half a year, menstruation resumed, and Wind syndrome healed. Thus, bland diet is valuable.
*Lun Feng* states: Wind Qi enters with Taiyang, moves through Shu points, spreads between muscle layers, interferes with Wei Qi, obstructing flow, causing muscle swelling and sores. Stagnant Wei Qi fails to move, causing tissue dysfunction. Li Feng involves hot Ying Qi, turbid Qi, leading to nasal pillar decay, pallor, skin ulcers. Cold-Wind lodging in vessels without departing is named Li Feng or Han Re (Cold-Heat).
*Chang Ci Jie Lun* states: Da Feng with heavy joints and lost eyebrows/beards is named Da Feng. Prick muscles until sweating for 100 days; prick marrow until sweating for 100 days. Total 200 days until eyebrows/beards regrow, then stop needling. For Li Feng, always prick swellings with sharp needles, press to expel evil Qi, stop when swelling resolves. Eat regular food, avoid other foods.
*Mai Yao Jingwei Lun* states: Pulse Wind transforms into Li.
Zhang Jingyue stated: Li Feng is Da Feng, also called Lai Feng, popularly Da Ma Feng. Though named Wind, it is not exogenous Wind. It is actually Yin-Li turbid evil Qi from the world, transforming via Wood-Wind into Wind-Heat parasites, or Damp-Toxin on skin spreading to Ying-Wei, or from uncleanness/contagion generating parasites. Parasites are governed by Jueyin (Wind-Wood), which generates five types of worms. Initially unnoticed, they multiply over time, becoming incurable. It is the most evil, dangerous, and ugly syndrome. *Qianjin Fang* says it is retribution for extreme cruelty, hence hard to treat. Sun Simiao treated hundreds, none survived due to taboo violations. Only one woman recovered after taking Jiajian Siwu Tang for 100+ doses over 6 months. Danxi treated five, only one survived due to poverty/abstinence. Others relapsed in 2-3 years and died. Thus, extraordinary secret recipes are rarely effective. I dare not claim knowledge or prescribe blindly. Ancient theories are detailed; if applied correctly, they prolong life and prevent premature death. Among all sources, Xue Lizhai's *Liyang Jiyao* is most complete. I select its essentials and rational theories as guidelines.
*Qipo Ebing Lun* states: Jifeng has 400+ types, summarized as Five Winds: Huang Feng (Yellow), Qing Feng (Green), Bai Feng (White), Chi Feng (Red), Hei Feng (Black). Corresponding to Five Zang. Each Wind generates a Worm: Yellow Worm, Green Worm, White Worm, Red Worm, Black Worm, eating the Five Zang. Eating Spleen alters speech/voice; eating Liver drops brows/lashes; eating Heart causes body sores; eating Lungs collapses nasal pillar/polyps; eating Kidneys causes tinnitus (rumbling); eating Skin causes顽痹 (stubborn numbness); eating Tendons causes joint detachment. Five Winds + Five Zang + Many Worms entering Marrow destroy the body, named Jifeng. Jifeng is the root of Li Feng. Early stages: piercing pain (Ci Feng); crawling sensation (You Feng); twitching (Che Feng); insensitivity (Wan Feng); nodules starting head/face (Shun Feng); nodules starting feet (Ni Feng); coin-shaped/red-white-green-black patches (KT Feng). Sores, fish-scale skin, elm seeds, itching/pain, yellow discharge, joint rot, pus/blood, variable colors. Causes: Cold/Heat imbalance, flowing to Zang, penetrating Marrow, overexertion, dirty diet, immoderate sex, extreme exhaustion, profuse sweating. Accumulated Heat in Zang generates many worms eating Zang/Marrow/Skin/Tendons/Joints, named Li Feng. Black Worms are hardest to treat. Patients should abandon possessions/family, retreat to mountains for quiet recuperation; treatment will surely succeed.
Xu Donggao stated: Classics say: "Sweating cures sores." Since Lai Feng is the worst of Winds/Sores, it is called Li Feng. Prolonged Heat generates Wind; Li Feng is formed by肃杀 (killing/drying) Qi. Without diaphoresis, how to remove Wind Toxin? Thus, sweating is the most crucial method; other formulas follow sequentially.
He further stated: Severe body itching is due to Wind Pathogen stagnation and Blood failing to nourish skin. Use Siwu Tang with Huangqin (Scutellariae Radix) and Baizhi (Angelicae Dahuricae Radix), mixed with Fuping (Moss powder), to induce sweating and heal.
Zhang Zihe stated: One sweat equals a thousand needles. Bloodletting is less comprehensive than sweating. However, sweating is bleeding, and bleeding is sweating; they are equivalent.
Shen Ziliang stated: Human life derives from Heaven-Earth Yin-Yang, Father's Essence, Mother's Blood. External pores, internal organs, bones, meridians correspond to Heaven. Heaven is one great Heaven; Man is one small Heaven. Heaven has weather (Clear/Dark, Wind/Cold/Summer-Heat/Damp/Dry/Fire). Humans have Qi-Blood fluctuations and emotions. Thus, gentlemen regulate diet, guard sexual activity, moderate emotions, and nurture health. Avoid Seven Emotions internal injury, Wind-Cold, Summer-Heat-Damp, Dryness-Fire external invasion. Then disease does not arise, preventing premature death. *Shanggu Tianzhen Lun* says: "Superior doctors treat disease before it arises." My view: It is self-healing/self-prevention. Lack of moderation, indulgence in desire/food/emotions leads to Qi-Blood disharmony, Six Evils invasion, and hundred diseases. Like Li Feng, there are 36 types varying in severity. It is cruel and vicious, causing deformity, hair loss, limb paralysis, muscle ulceration, finger loss, pus/discharge, foul odor. People shun it. How can one be careless? Ancients listed five causes: 1. Wind-Water Yin-Yang damage; 2. Source/Contagion; 3. Turbid Qi/Toxin injection; 4. Improper care; 5. Cold/Contraction/Stagnation. This is general. Onset varies: adulthood, teens (14-15), childhood (4-5). Etiology differs. Adult onset: failure to moderate desire damages Kidney Yuan, dries fluids, loosens pores, invites Cold-Damp. Long-term accumulation, Water deficiency fails to nourish Wood, Liver Xu stirs Wind. Wind moves/changeable, combines with Damp to create Heat. Failure to驱散 (disperse) or tonify makes roots firm, worsening daily. Wind guides Damp-Heat Toxin to attack skin/muscle, blocking meridians. Qi-Blood stops. Initially, slight numbness in head/face/hands/feet. If family recognizes evil omen, seeks doctor immediately, assesses depth/shallowness of Wind-Damp...
