经义
黄帝问曰∶痹之安生？岐伯对曰∶风、寒、湿三气杂至，合而为痹。风气胜者为行痹；寒气胜者为痛痹；
湿气胜者为着痹也。帝曰∶其有五者何也？岐伯曰∶以冬遇此为骨痹；以春遇此
为筋痹；以夏遇此为脉痹；以至阴遇此为肌痹；以秋遇此为皮痹。○帝曰∶痹其时有死者，或疼久者，或易已
者，其故何也？岐伯曰∶其入脏者死，其留连筋骨间者疼久，其留皮肤间者易已。○帝曰∶痹或痛、或不痛、
或不仁、或寒、或热、或燥、或湿、其故何也？岐伯曰∶痛者，寒气多也，有寒故痛也。其不痛不仁者，病久
入深，营卫之行涩，经络时疏，故不痛。皮肤不荣，故为不仁。其寒者，阳气少，阴气多，与病相益，故寒也。
其热者，阳气多，阴气少，病气胜，阳乘阴，故为痹热。其多汗而濡者，此其逢湿甚也。阳气少，阴气盛，雨
气相感，故汗出而濡也。○帝曰∶夫痹之为病，不痛何也？岐伯曰∶痹在于骨则重；在于脉则血凝而不流；在于
筋则屈不伸；在于肉则不仁；在于皮则寒。故具此五者，则不痛也。凡痹之类，逢寒则急，逢热则纵。○卧
出而风吹之，血凝于肤者为痹。（《素问》）
病在阳者命曰风；病在阴者命曰痹；阴阳俱病命曰风痹。○屈而不伸者，其病在筋；伸而不屈者，其病
在骨。（《灵枢》）
哲言
经热则痹，络血则痿。○邪中于经则痹，邪中于络则痿。（叶天士）
痹∶有痹于分肉者；有痹于营卫者；有痹于躯壳之内胸胁之间者；有痹于气分者；有痹于血分者。痹于
分肉者，则痛痹、周痛之类是也；痹于营卫者，则中风、四肢苦烦之类是也；痹于躯壳之内胸胁之间者，胸痹
之类是也；痹于气分者，黄胆之类是也；痹于血分者，血痹之类是也。痹虽同而痹之所在不同，证亦因之迥异，
不可不察也。○痉病非风不成，虽有寒亦附于风而已；痹病非寒不成，虽有风亦附于寒而已。（魏荔彤）
风痹一证，即今人所谓痛风也。盖痹者，闭也，以血气为邪所闭，不得通行而病也。如《痹论》曰∶风
气胜者为行痹。盖风者善行数变，故其为痹，则走注历节，无有定所，此阳邪也。
曰∶寒气胜者为痛痹。以血气受寒则凝涩留聚，聚则为痛，此阴邪也。曰∶湿气胜者为着痹。以血气受湿则濡
滞，濡滞则肢体沉重而疼痛顽木，留着不移，亦阴邪也。凡此三者，即痹之大则也。此外如脏腑之痹，虽以饮
食居处皆能致之，然必重感于邪，而内连脏气，则合而为痹矣。若辨其轻重，则在皮肤者轻，在筋骨者甚，在
脏腑者更甚。若辨其寒热，则多热者方是阳证，无热者便是阴证。然痹本阴邪，惟寒者多而热者少，此则不
可不察。○《经》曰∶风寒湿三气杂至，合而为痹。又曰∶在阳者命曰风，在阴者命曰痹，何也？盖三气之合，
乃专言痹证之所因也。曰在阳为风，在阴为痹，又分言表里之有殊也。如风之与痹，本皆由感邪所致，但外有
表证，而见发热头疼等证，或得汗即解者，是皆有形之谓，此以阳邪在阳分，是即伤寒、中风之属也。故病在
阳者命曰风。若既受寒邪，而初无发热头疼等证，或有汗，或无汗，而筋骨之痛如故，及延绵久不能愈者，是
皆无形之谓，此以阴邪直走阴分，即诸痹之属也。故病在阴者命曰痹。其或既有表证，而疼痛又不能愈，此即
半表半里、阴阳俱病之证。故阴阳俱病者，命曰风痹。此所以风病在阳而痹病在阴也。然则诸痹者皆在阴分，
亦总由真阴衰弱，精血亏损，故三气得以乘之。《经》曰∶邪入于阴则痹，正谓此也。（张景岳）

如果患者体质壮实，属于膏粱厚味之疾，治疗应当采用泻法，可选用三化汤或调胃承气汤。但如果脾虚，则不能使用这些方剂。《黄帝内经》说：土气不足就会下陷。“卑”指低下；“陷”指坑洞。四肢都依赖胃气滋养，但胃气不能直接到达经脉，必须依靠脾的转输才能被四肢禀受。现在脾病不能协助胃传输津液，四肢得不到水谷精气的滋养，正气日益衰弱，脉道运行不畅，筋骨肌肉都缺乏生气，所以出现痿废不用的症状。治疗使用十全散加减四物汤。（出自《保命集》）
经义
黄帝问道：痹证是如何产生的？岐伯回答说：风、寒、湿三种邪气混杂侵袭人体，结合而成痹证。风气偏胜的叫行痹；寒气偏胜的叫痛痹；湿气偏胜的叫着痹。黄帝问：为什么有这五种分类呢？岐伯说：在冬季感受这种邪气叫骨痹；在春季感受叫筋痹；在夏季感受叫脉痹；在长夏（至阴之时）感受叫肌痹；在秋季感受叫皮痹。○黄帝问：痹证有的导致死亡，有的疼痛持久，有的容易痊愈，这是什么原因？岐伯说：邪气侵入内脏的会死亡，邪气留连在筋骨间的疼痛持久，邪气停留在皮肤间的容易痊愈。○黄帝问：痹证有的疼痛，有的不疼痛，有的麻木不仁，有的发冷，有的发热，有的干燥，有的潮湿，这是什么原因？岐伯说：疼痛的，是因为寒气多，有寒所以疼痛。不疼痛且麻木不仁的，是因为病久深入，营卫运行涩滞，经络空虚，所以不痛。皮肤失去荣养，所以麻木不仁。发冷的，是因为阳气少，阴气多，与病邪相合，所以发冷。发热的，是因为阳气多，阴气少，病气盛，阳热乘袭阴分，所以成为热痹。多汗且湿润的，是因为逢受了严重的湿气。阳气少，阴气盛，雨湿之气相感，所以出汗且湿润。○黄帝问：痹证为什么不痛呢？岐伯说：痹在骨则身体沉重；在脉则血液凝滞不流；在筋则屈伸不利；在肉则麻木不仁；在皮则寒冷。具备这五种情况，就不痛了。大凡痹类疾病，逢遇寒冷则拘急，逢遇热则弛纵。○睡觉后出门受风吹，血液凝滞在皮肤的就形成痹证。（出自《素问》）
病在阳分的叫风；病在阴分的叫痹；阴阳俱病的叫风痹。○屈伸不利的，病在筋；伸展不能屈曲的，病在骨。（出自《灵枢》）
哲言
经络受热则成痹，络脉瘀血则成痿。○邪气中于经则成痹，邪气中于络则成痿。（叶天士）
痹证：有痹阻在分肉的；有痹阻在营卫的；有痹阻在躯壳之内胸胁之间的；有痹阻在气分的；有痹阻在血分的。痹阻在分肉的，就是痛痹、周痛之类的；痹阻在营卫的，就是中风、四肢烦苦之类的；痹阻在躯壳之内胸胁之间的，就是胸痹之类的；痹阻在气分的，就是黄疸之类的；痹阻在血分的，就是血痹之类的。痹虽然相同，但痹阻的部位不同，证候也因此迥异，不可不仔细考察。○痉病没有风就不能形成，虽然有寒也是依附于风的；痹病没有寒就不能形成，虽然有风也是依附于寒的。（魏荔彤）
风痹一证，就是今人所说的痛风。大概“痹”的意思是闭塞，因为气血被邪气闭阻，不能通行而发病。如《痹论》说：风气偏胜的叫行痹。风性善行数变，所以它作为痹证，就游走不定，历节疼痛，没有固定位置，这是阳邪。又说：寒气偏胜的叫痛痹。因为气血受寒则凝涩留聚，聚结就疼痛，这是阴邪。又说：湿气偏胜的叫着痹。因为气血受湿则濡滞，濡滞则肢体沉重而疼痛顽木，留着不移，也是阴邪。大凡这三种，就是痹证的大原则。此外如脏腑的痹证，虽然饮食居处都能导致，但必须再次感受邪气，内连脏气，才合而为痹。如果辨别轻重，在皮肤的轻，在筋骨的严重，在脏腑的更严重。如果辨别寒热，多热的才是阳证，无热的便是阴证。然而痹本属阴邪，只有寒的多而热的少，这一点不可不察。○《内经》说：风寒湿三气混杂侵袭，合而为痹。又说：在阳的叫风，在阴的叫痹，为什么呢？大概三气的结合，是专门讲痹证的成因。说在阳为风，在阴为痹，又是分别讲述表里的不同。如风和痹，本来都是由感受邪气所致，但如果有表证，见到发热头疼等证，或者得汗即解的，这些都是有形之邪，这是阳邪在阳分，就是伤寒、中风的类别。所以病在阳的叫风。如果已经感受寒邪，起初没有发热头疼等证，或者有汗或无汗，而筋骨疼痛依旧，以及拖延很久不能痊愈的，这些都是无形之邪，这是阴邪直走阴分，就是各种痹证的类别。所以病在阴的叫痹。如果既有表证，而疼痛又不能痊愈，这就是半表半里、阴阳俱病的证候。所以阴阳俱病的，叫风痹。这就是风病在阳而痹病在阴的原因。然而各种痹证都在阴分，也总归是由于真阴衰弱，精血亏损，所以三气得以乘虚而入。《内经》说：邪入于阴则痹，正是说的这个意思。（张景岳）

太阳病，骨节疼痛而且烦躁，脉沉而细的，这叫湿痹。湿痹的表现，小便不利，大便反而快利，只应当通利小便。○血痹病是怎么得的？回答说：富贵之人骨弱肌肤盛，再加上疲劳出汗，睡觉时不时动摇，又受到微风侵袭，于是得了此病。只要脉象微涩，在寸口、关上部位稍紧，适宜用针刺引导阳气，使脉象调和，紧象去除就能痊愈。○血痹阴阳俱微，寸口、关上脉微，尺中脉小紧，外证身体麻木不仁像风痹的样子，用黄耆桂枝五物汤主治。（出自《金匮要略》）
治疗行痹，以祛风为主，辅以散寒祛湿，参用补血药剂。所谓治风先治血，血行风自灭。治疗痛痹，以散寒为主，辅以疏风燥湿，参用补火药剂。所谓热则流通，寒则凝塞，通则不痛。治疗着痹，以燥湿为主，辅以祛风散寒，参用补脾药剂。因为土旺则能胜湿，气足自然没有麻木顽硬。（程钟龄）
痛痹一证，是肝肾有病，筋脉失于荣养，虚火乘于经络，出现红肿疼痛。如果肿痛但不红，得温稍定，又属于虚寒。初起恶寒发热，类似伤寒，多在四肢经络之间肿痛，或左右移动，或上下游行，脉象或大而数，或细而数，或细而涩，或大而空。医家拘泥于风、寒、湿三气混杂侵袭的说法，一概以外邪治疗，病势逐渐加重，阴液逐渐耗损，造成虚虚之祸，不可胜言。大概风自内动，湿热内生的，属于阴虚有火，用发表、清热法，证候多变为虚损。寒自内发，寒湿内生的，属于阳虚无火，用发表、清热法，证候多变为中风。即使其人身体壮实，果系外邪侵入，服用表散清凉药后痛止肿消，也必须用扶脾益血的药物来收后效。又有过服热药，胃中蕴热日深，筋脉不利，手足肿痛如锥刺，因为阳明主宗筋，筋热则痛，经过关节成为热痹。证见口渴面赤，便秘尿短，脉数大有力，或洪大有力，所谓历节白虎风证。治疗宜用黄芩、黄连、知母、黄柏、生地、石膏、玄参之类，清热降火。然后热解筋舒，疼痛才能安定。医家拘泥于风、寒、湿三气混杂侵袭的说法，不是表散风寒，就是温经利湿，越服药越热。虽然如此，《内经》有邪入内脏者死，留连筋骨间者痛久，停留皮肤间者易愈的宗旨。足见内生之风、寒、湿三气，鼓舞于经络之中，恐怕用攻伐耗损的药物，会使脏气空虚，真阴欲竭。外入之风、寒、湿三气，鼓舞于经络之中，恐怕用攻伐耗损的药物，会使脏气受敌，真阳欲脱。况且痹，就是闭塞的意思。脉络涩滞而缺少宣通的机转，气血凝滞而缺少流动的态势。治疗方法非壮水益阴，就是补气生阳；非急于救肝肾，就是致力于培补脾胃，这样病退而根本不动摇。如果拘泥于三气混杂为必不可留之邪，每天从事于攻伐，实证安顿而虚证危险了。（出自《会心录》）
痛痹之证，多有白天轻晚上重的，这是阴邪在阴分。那些遇风雨阴晦加重的，这是阴邪侮阳的寒证。有的遇暖遇热加重的，这是湿热伤阴的火证。有火的宜从清凉，有寒的宜从温热。如果筋脉拘滞，伸缩不利的，这是血虚、血燥的证候，非养血养气不可。○治疗痹证的方法，最宜峻补真阴，使血气流行，则寒邪随之而去。如果过用风湿等药，再伤阴气，必定反而增加病情。（张景岳）
痹，就是闭塞不通的意思。正气被邪气阻遏，脏腑经络不能畅达，都是由于气血亏损，腠理疏松，风寒湿三气得以乘虚外袭，留滞于内，致使湿痰、浊血流注凝涩而得病。有卫阳疏泄，风邪入络而成痹的，治疗以宣通经脉，甘寒去热。有经脉受伤，阳气不能护持而成痹的，治疗以温养通补，扶持生气。有暑伤气，湿热入络而成痹的，用舒通络脉的药剂，使清阳流行。有风湿肿痛而成痹的，用人参、白术益气，佐以风药。有湿热伤气，及湿热入血络而成痹的，用固卫阳以驱邪，及宣通营络兼治奇经。有肝阴虚，疟邪入络而成痹的，治疗以寒苦滋阴，通逐缓攻。有寒湿入络而成痹的，以微通其阳，兼以通补为治。有气滞热郁而成痹的，从气分宣通为治。有肝胃虚滞而成痹的，以两补厥阴、阳明为治。有风、寒、湿入下焦经隧而成痹的，用辛温宣通经气为主。有肝胆风热而成痹的，用甘寒和阳、宣通脉络为主。有血虚络涩及营虚而成痹的，以养营、养血为主。又有周痹、行痹、肢痹、筋痹，及风、寒、湿三气杂合之痹，也不外乎流畅气血，祛邪养正，宣通脉络诸法。（出自《临证指南医案》）
肩背、肢节、骨腕、筋会之处注痛，多属痰凝气滞。不拘男女，选取神旺气长者，令其口对患处，不呵不吸，极力努气，使气透入，觉得暖至热，再换一人，以痊愈为度。肾虚腰痛，令掌心摩擦万遍，或令进气于肾俞穴。丹田冷的，也摩擦并进气于脐轮，其功效尤其猛烈。○痿痹疾者，偎卧于壮阴之怀，久之，生气和浃，病气潜消。（韩飞霞）

周巡台太夫人，先患手臂不仁，接着逐渐足膝无力。服用二陈汤、六君子汤百剂，两脚不能起立。又服用鹿茸、虎胫、人参，疼痛非常。我对他说：积热在肠胃，治疗宜用攻下。他非常害怕。我说：贼在关内，不迅速歼除，能安枕吗？他皱眉不敢，于是说：我家自制有河车大造丸，暂且服用半月，再攻下如何？他答应了。私下将承气汤合白虎汤制成丸药给他服用，五日而痛止，十日而能行走，再用回天丸调理三月而痊愈。○郑秋田令眷，左小腿浮肿，服用苡仁防风汤，小腿消肿，膝盖以上麻痛，呕吐寒热。数日后，腿忽然肿大，颜色时黑时红，形状像马脸，目口鼻俱全，敷药不退。我取旧驿馆骡蹄底下皮烧灰，和贝母、白芥子、干马粪末，敷两次而消。内服加减漏芦汤，寒热也止，改服八珍汤调理而痊愈。（程华仲）
一人七十多岁。患尾闾骨痛，脉沉迟细涩。其痛在督脉之根，督脉属阳，则阳分虚了。方用鹿角胶以补督脉，人参、附子温补下元而宣阳气，加当归、地黄、枸杞、杜仲、续断、牛膝、五加皮以补髓养血，用酒煎以行药力，数服而效。○一老人早起梳洗，忽右手自肩膊至指尖其痛非常，不能屈伸。医生说是老人血虚，我想血虚痛不应如此突然，也不至于如此严重。脉浮数而紧，乃是风寒无疑，方用羌活、防风、秦艽、川芎、五加皮、桂枝、桑枝、当归，服二剂痛减，手能运动，乃去羌活，加黄芪，倍用当归，再服四剂而痊愈。（吴天士）
一人感受风湿，得白虎历节风证，偏身抽痛，足不履地者三年，百治不效。一天夜里，梦见有人给木通汤。于是用木通二两，长流水煎，服后一时许，偏身痒甚，上体发红丹如豆大，汗出至腰，上体便不痛了。次日如前煎服，下体又发红丹，汗出至足，通身舒畅。一月后，人壮气复，步履如初。后治数人皆验，盖痛则不通，通则不痛。（出自《证治准绳》）
湖南一行主人风疾在榻，交易写算，尚能应客。一卖药者在门，拥挤多人，有碍客商，厌恶他，命令赶走。卖药者回头说：不要赶我，我为你好起足疾。主人忍耐。问足废几年？说：三年了。又问痛否？说：阴雨时掣痛。令铲骡蹄底下皮两许，酒洗炙末，炙乳香一钱和入，分三日酒冲服。三日后，能下榻移步，再服一料疾愈。江斯荇亲眼见到他的治疗，问我：骡蹄治疯疾，书上有记载吗？我说：没见过。问何以速效？我说：骡马善行去风，其力在蹄，加乳香，借酒力，怎能不快？阿胶，骡皮所煎，尚能去风，何况骡蹄呢？这虽然在方书之外，实在理法之中，记录下来以广见识。（许宣治）
附麻木
麻，就像痹一样，虽然不知痛痒，尚觉气微流行；木则不仅不知痛痒，气也不觉流行。（出自《医学入门》）
麻木，因营卫之行涩，经络凝滞所致。多见于手足，因为经脉皆起于指端，四末行远，气血罕到故也。不可误作风治。（出自《证治汇补》）
麻木为风，三尺童子皆知之。细核则有区别，如人久坐亦麻木，绳缚之人亦麻木，此非有风，乃气不行也。当行其气，则麻木自去矣。（李东垣）
麻是气虚，木是湿痰、死血。然则曰麻、曰木者，以不仁中分而为二也。虽然亦有气血俱虚，但麻而不木者；亦有虚而感湿，麻木兼作者；又有因虚而感风、寒、湿三气乘之，周身掣痛麻木并作者，古方谓之周痹。治宜先汗后补，以类推治。（朱丹溪）
附痒
诸痛痒疮，皆属心火。（出自《素问》）
痛者阴也，痒者阳也。○足厥阴虚则暴痒，任脉虚则痒搔。（出自《灵枢》）
人近火气者，热微则痒，热甚则痛，附近则灼而为疮，皆火之用也。痒者，美疾也，故火旺于夏，而万物蕃美也。炙之以火，渍之以汤，而痒转甚者，热之所使也。因而痒去者，热令皮肤缓纵，腠理疏通，阳气得泄，热散而去故也。夏热肤痒，而以冷水沃之不去者，寒能收敛，腠理闭密，阳气郁结，不能散越，怫热内作故也。痒得爬而解者，痒为火化，爬令皮肤辛辣而属金化，辛能散，故金化见则火分解矣。或谓痛为实，痒为虚者，非谓虚为寒也，正谓热之微甚。（刘河间）
诸痒为虚，血不荣于肌腠，所以痒也。当用滋补药以养阴血，血和肌泽，痒自不作。（出自《丹溪心法》）
附鹤膝风
If the patient's constitution is robust and the condition belongs to diseases caused by rich and greasy diet, treatment should employ purgation. One may select Sanhua Tang (Three Transformations Decoction) or Tiaowei Chengqi Tang (Regulate the Stomach and Direct Downward Decoction). However, if there is Spleen deficiency, these formulas should not be used. The *Classic* states: "When Earth Qi is insufficient, it sinks." "Bei" (low) refers to being low; "Xian" (sink) refers to a pit. The four limbs receive Qi from the Stomach, but Stomach Qi cannot directly reach the meridians; it must rely on the Spleen's transportation to be distributed to the limbs. Now, due to Spleen disease, it cannot assist the Stomach in transporting fluids and nutrients. The four limbs do not receive water and grain Qi, leading to a daily decline of Qi, unsmooth meridian pathways, and a lack of Qi generation for sinews, bones, muscles, and flesh, resulting in flaccidity and inability to use them. Treatment utilizes Shiquan San (Ten Complete Powder) modified with Siwu Tang (Four Substances Decoction). (From *Baoming Ji*)
Scriptural Meaning
The Yellow Emperor asked: How does Bi syndrome arise? Qibo replied: The three pathogens—Wind, Cold, and Dampness—mix and invade together, combining to form Bi syndrome. When Wind pathogen predominates, it is called Xing Bi (Wandering Bi); when Cold predominates, it is called Tong Bi (Painful Bi); when Dampness predominates, it is called Zhuo Bi (Fixed Bi). The Emperor asked: Why are there five categories? Qibo said: Contracting this in Winter results in Gu Bi (Bone Bi); in Spring, Jin Bi (Sinew Bi); in Summer, Mai Bi (Vessel Bi); during the late summer (Zhiyin period), Ji Bi (Muscle Bi); and in Autumn, Pi Bi (Skin Bi). The Emperor asked: Some Bi cases result in death, some have prolonged pain, and some heal easily. What is the reason? Qibo said: If the pathogen enters the Zang organs, death ensues; if it lingers between sinews and bones, pain persists; if it stays in the skin, it heals easily. The Emperor asked: Some Bi cases are painful, some are not; some involve numbness, some cold, some heat, some dryness, some dampness. What is the cause? Qibo said: Pain arises from excessive Cold; thus, Cold causes pain. Lack of pain and numbness occur because the disease has penetrated deeply over time, causing sluggish Ying and Wei circulation and occasional emptiness in the meridians, hence no pain. The skin loses nourishment, resulting in numbness. Cold sensations arise from deficient Yang Qi and abundant Yin Qi, which combine with the pathogen, causing cold. Heat sensations arise from abundant Yang Qi and deficient Yin Qi, where the pathogenic heat overwhelms the Yin, leading to Re Bi (Hot Bi). Profuse sweating and dampness occur when encountering severe Dampness. With deficient Yang and abundant Yin, the external rain/dampness resonates internally, causing sweat and dampness. The Emperor asked: Why does Bi sometimes not hurt? Qibo said: When Bi is in the bone, the body feels heavy; in the vessels, blood coagulates and stagnates; in the sinews, flexion and extension are impaired; in the flesh, there is numbness; in the skin, there is cold. Possessing all five conditions results in no pain. Generally, Bi syndromes contract when exposed to Cold and relax when exposed to Heat. Sleeping and then going out into the wind causes blood to coagulate in the skin, forming Bi. (From *Su Wen*)
Diseases in the Yang aspect are called Feng (Wind); diseases in the Yin aspect are called Bi; diseases affecting both Yin and Yang are called Feng Bi. Flexion without extension indicates disease in the sinews; extension without flexion indicates disease in the bones. (From *Ling Shu*)
Philosophical Sayings
Heat in the Jing meridians leads to Bi; blood stasis in the Luo collaterals leads to Wei (Flaccidity). Pathogens striking the Jing meridians cause Bi; pathogens striking the Luo collaterals cause Wei. (Ye Tianshi)
Bi can obstruct the Fenrou (muscle intervals); it can obstruct Ying and Wei; it can obstruct the interior of the torso between the chest and hypochondrium; it can obstruct the Qi level; it can obstruct the Blood level. Obstruction in the muscle intervals corresponds to Tong Bi and Zhou Bi; obstruction in Ying and Wei corresponds to Zhong Feng (Wind Stroke) and vexation in the four limbs; obstruction in the chest/hypochondrium corresponds to Xiong Bi (Chest Bi); obstruction at the Qi level corresponds to Huang Dan (Jaundice); obstruction at the Blood level corresponds to Xue Bi (Blood Bi). Although Bi is similar, its location differs, leading to vastly different manifestations, which must be carefully observed. Jing Spasm requires Wind to manifest; even if Cold is present, it attaches to Wind. Bi requires Cold to manifest; even if Wind is present, it attaches to Cold. (Wei Litong)
Feng Bi is what modern people call Tong Feng (Gout). "Bi" means closure; Qi and Blood are blocked by pathogens and cannot flow freely, causing disease. As stated in the *Bi Lun*: Wind predominance causes Xing Bi. Wind moves quickly and changes frequently, so this type of Bi wanders through joints without a fixed location; this is a Yang pathogen. Cold predominance causes Tong Bi. Qi and Blood congeal and stagnate due to Cold, accumulating to cause pain; this is a Yin pathogen. Dampness predominance causes Zhuo Bi. Qi and Blood become sticky and stagnant due to Dampness, causing heavy, painful, numb limbs that remain fixed; this is also a Yin pathogen. These three are the general principles of Bi. Additionally, Zang-Fu Bi can be caused by diet and lifestyle, but it requires repeated exposure to pathogens connecting internally to Zang Qi to form Bi. Regarding severity: Skin involvement is mild; Sinew/Bone involvement is severe; Zang-Fu involvement is most severe. Regarding Cold/Heat: Cases with much heat are Yang syndromes; those without heat are Yin syndromes. However, Bi is inherently a Yin pathogen, mostly Cold with little Heat; this must be noted. The *Classic* says: Wind, Cold, and Dampness mix to form Bi. It also says: In Yang it is called Feng, in Yin it is called Bi. Why? The combination of the three pathogens explains the etiology of Bi. Saying "In Yang is Feng, in Yin is Bi" distinguishes exterior from interior. Feng and Bi both result from pathogen invasion, but if there are exterior signs like fever and headache, or resolution after sweating, these are tangible pathogens; Yang pathogens in the Yang aspect belong to Shang Han (Cold Damage) and Zhong Feng. Thus, disease in Yang is called Feng. If Cold pathogen is contracted without initial fever/headache, with or without sweat, but joint/bone pain persists or drags on, these are intangible pathogens; Yin pathogens moving directly into the Yin aspect belong to various Bis. Thus, disease in Yin is called Bi. If exterior signs exist but pain persists, it is a Half-Exterior/Half-Interior syndrome affecting both Yin and Yang, called Feng Bi. This explains why Feng is in Yang and Bi is in Yin. All Bis reside in the Yin aspect, generally due to deficiency of True Yin and depletion of Essence and Blood, allowing the three pathogens to invade. The *Classic* says: "Pathogens entering Yin cause Bi," referring to this. (Zhang Jingyue)
Supplement
Taiyang disease with bone/joint pain and irritability, with a deep and fine pulse, is named Shi Bi (Damp Bi). Signs of Shi Bi include difficult urination and loose stools; treatment should focus on promoting urination. Xue Bi (Blood Bi) arises how? It affects noble persons with weak bones but full flesh. Due to fatigue and sweating, combined with restless sleep and exposure to slight wind, they contract it. The pulse is slightly choppy and faint, tight at Cun and Guan positions. Acupuncture should guide Yang Qi; when the pulse harmonizes and tightness disappears, healing occurs. Xue Bi with both Yin and Yang deficiency shows faint pulses at Cun/Guan and slight tightness at Chi. Exterior signs include body numbness resembling Feng Bi. Huangqi Guizhi Wuwu Tang (Astragalus and Cinnamon Twig Five-Ingredient Decoction) is indicated. (From *Jin Gui Yao Lue*)
Treating Xing Bi focuses on dispersing Wind, assisted by dispelling Cold and Dampness, supplemented with Blood-nourishing agents. "To treat Wind, first treat Blood; when Blood flows, Wind extinguishes itself." Treating Tong Bi focuses on dispersing Cold, assisted by venting Wind and drying Dampness, supplemented with Fire-warming agents. "Heat promotes flow; Cold causes blockage; flow prevents pain." Treating Zhuo Bi focuses on drying Dampness, assisted by dispelling Wind and Cold, supplemented with Spleen-tonifying agents. When Earth is strong, it overcomes Dampness; when Qi is sufficient, numbness and stiffness disappear. (Cheng Zhongling)
Tong Bi involves Liver and Kidney pathology, where sinews and vessels lose nourishment, and deficient fire attacks the meridians, causing redness, swelling, and pain. If swollen/painful but not red, and relieved by warmth, it belongs to Deficient Cold. Initial stages mimic Shang Han with aversion to cold and fever, often with swelling/pain in limb meridians, moving left/right or up/down. Pulses may be large-rapid, fine-rapid, fine-choppy, or large-empty. Physicians clinging to the "Wind-Cold-Damp mixing" theory often treat solely with exterior-dispelling methods, worsening the condition and depleting Yin fluids, causing "deficiency of deficiency." Wind moving internally with endogenous Damp-Heat belongs to Yin deficiency with fire; exterior-releasing or clearing methods often lead to consumptive disorders. Cold originating internally with endogenous Cold-Damp belongs to Yang deficiency without fire; such treatments often lead to stroke-like symptoms. Even if the constitution is solid and exogenous pathogens invaded, once pain/swelling subside with cooling/dispersing herbs, Spleen-fortifying and Blood-nourishing herbs are needed for recovery. Overuse of hot herbs can deepen stomach heat, causing sinew vessel dysfunction and stabbing pain in hands/feet. Since Yangming governs the tendons, tendon heat causes pain spreading through joints as Re Bi. Symptoms include thirst, red face, constipation, short urine, and forceful rapid/large pulses, known as Li Jie Bai Hu Feng (White Tiger Joint Pain). Treatment uses Huang Qin, Huang Lian, Zhi Mu, Huang Bo, Sheng Di, Shi Gao, Xuan Shen to clear heat and descend fire. Once heat resolves and sinews relax, pain settles. Physicians stuck on the "Wind-Cold-Damp" theory only disperse Wind/Cold or warm meridians/drain dampness, increasing heat. Although the *Nei Jing* states entry into Zang causes death, lingering in sinews/bones causes long pain, and staying in skin heals easily, this highlights that endogenous Wind/Cold/Damp stirring in meridians risks emptying Zang Qi and exhausting True Yin if attacked harshly. Exogenous Wind/Cold/Damp stirring in meridals risks depleting True Yang if attacked harshly. Bi means closure; meridians are choppy lacking ventilation, Qi/Blood stagnate lacking flow. Treatment must either strengthen Water/nourish Yin or tonify Qi/generate Yang; urgently saving Liver/Kidney or cultivating Spleen/Stomach ensures the root remains stable. Clinging to "three pathogens" as invincible evils and constantly attacking harms the deficient while stabilizing the excess. (From *Huixin Lu*)
Tong Bi often worsens at night, indicating Yin pathogens in the Yin aspect. Worsening in wind/rain/cloudy weather indicates Yin pathogens insulting Yang (Cold syndrome). Worsening with warmth/heat indicates Damp-Heat injuring Yin (Fire syndrome). Those with fire require cooling; those with cold require warming. If sinews/vessels are stiff with limited movement, it is Blood deficiency/dryness, requiring Blood and Qi nourishment. Treating Bi best employs vigorous tonification of True Yin to promote Qi/Blood flow, driving out Cold. Overusing Wind-Damp drugs injures Yin and worsens the disease. (Zhang Jingyue)
Bi means closure and obstruction. Healthy Qi is blocked by pathogens; Zang-Fu and meridians cannot flow smoothly. This stems from Qi/Blood deficiency and loose cou li, allowing Wind/Cold/Damp to invade and stagnate internally, causing Phlegm-Damp and turbid blood to flow and coagulate. If Wei Yang is loose and Wind enters collaterals, treat by unblocking meridians with Sweet-Cold herbs to clear heat. If meridians are injured and Yang cannot protect, treat with Warm-Nourishing-Unblocking methods to support vital Qi. If Summerheat injures Qi and Damp-Heat enters collaterals, use agents to soothe/unblock collaterals to allow Clear Yang to flow. If Wind-Damp causes swelling/pain, use Ren Shen and Bai Zhu to tonify Qi, assisted by Wind-draining herbs. If Damp-Heat injures Qi and enters Blood collaterals, secure Wei Yang to expel pathogens and unblock Ying collaterals, addressing Extraordinary Vessels. If Liver Yin is deficient and Malaria pathogens enter collaterals, treat with Bitter-Cold herbs to nourish Yin and gently purge. If Cold-Damp enters collaterals, mildly unblock Yang and combine with tonification. If Qi stagnation and Heat depression cause Bi, unblock from the Qi level. If Liver/Stomach deficiency/stagnation causes Bi, tonify Jueyin and Yangming. If Wind/Cold/Damp enter lower Jiao channels, use Pungent-Warm herbs to unblock channel Qi. If Liver/Gallbladder Wind-Heat causes Bi, use Sweet-Cold herbs to harmonize Yang and unblock collaterals. If Blood deficiency/collateral chopiness or Ying deficiency causes Bi, nourish Ying and Blood. Zhou Bi, Xing Bi, Zhi Bi, Jin Bi, and mixed Wind/Cold/Damp Bi all follow methods of flowing Qi/Blood, expelling pathogens, nourishing healthy Qi, and unblocking collaterals. (From *Lin Zheng Zhi Nan*)
Pain at shoulders, back, joints, wrists, and tendon hubs often stems from Phlegm condensation and Qi stagnation. Regardless of gender, select a person with robust spirit and ample Qi. Have them place their mouth against the affected area, inhaling/exhaling normally, but forcefully pushing Qi inward until warmth/heat is felt. Switch persons until healed. For Kidney deficiency lumbar pain, rub palms ten thousand times or direct Qi into Shenshu acupoints. For cold Dantian, rub and direct Qi into the navel area; efficacy is potent. For Wei-Bi diseases, lie close to a person with strong Yin essence; over time, vital Qi harmonizes and disease Qi dissipates. (Han Feixia)
Any physician treating Bi without understanding its principles, using generic Wind-door remedies, commits medical error. (From *Yi Men Fa Lv*)
Selected Cases
Lu Wenhu suffered numbness in both feet. Self-administered Blood-activating herbs failed; Phlegm-attacking herbs also failed. Six months later, hands became numb, and an area one chi below the left umbilicus lost pain/itch sensation. I diagnosed this as Zhuo Bi per the Classic. Pulse was large but powerless, indicating Qi/Blood damage. Prescribed Shenxiao Huangqi Tang plus Fu Ling, Bai Zhu, Dang Gui, and Di Huang. Effective after ten doses. Continued with Shiquan Dabu Tang for fifty doses until recovered. (Li Shicai)
Madam Zhou, wife of Inspector Zhou, first had arm numbness, progressing to leg/knee weakness. Took Er Chen Tang and Liu Jun Zi Tang for a hundred doses, becoming unable to stand. Took Deer Antler, Tiger Tibia, and Ginseng, causing severe pain. I stated: Accumulated heat in intestines/stomach requires purging. He feared this greatly. I said: If the thief is inside the pass, will you sleep peacefully without eliminating him? He frowned but agreed, suggesting his family's Heche Dazao Wan for half a month before purging. I secretly made pills combining Chengqi Tang and Baihu Tang. Pain stopped in five days; walking resumed in ten days. Regulated with Huitian Wan for three months until cured. Lady Zheng Qiutian had left shin edema. Yi Ren Fang Feng Tang reduced swelling, but knee numbness/pain, vomiting, and chills/fever appeared. Days later, leg swelled massively, color shifting black/red, shape like a horse face. Topical meds failed. I used ash from old post-station mule hooves mixed with Bei Mu, Bai Jie Zi, and dried manure powder. Applied twice to resolve swelling. Internally prescribed Jian Lou Lu Tang; chills/fever ceased. Regulated with Bazhen Tang until cured. (Cheng Huazhong)
A man over seventy suffered tailbone pain with deep-slow-fine-choppy pulse. Pain located at the root of the Du Meridian (Yang aspect), indicating Yang deficiency. Formula: Lu Jiao Jiao to tonify Du Meridian; Ren Shen and Fu Zi to warm lower Yuan and disseminate Yang; Dang Gui, Di Huang, Gou Qi, Du Zhong, Xu Duan, Niu Xi, Wu Jia Pi to tonify marrow and nourish Blood. Decocted in wine to promote action. Effective after several doses. An elderly man suddenly experienced severe pain from right shoulder to fingertips upon waking/combing, unable to flex/extend. Doctor attributed it to Blood deficiency. I reasoned Blood deficiency pain wouldn't be so sudden/severe. Pulse was floating-rapid-tight, confirming Wind-Cold. Formula: Qiang Huo, Fang Feng, Qin Jiao, Chuan Xiong, Wu Jia Pi, Gui Zhi, Sang Zhi, Dang Gui. Two doses reduced pain, restoring hand movement. Removed Qiang Huo, added Huang Qi, doubled Dang Gui. Four more doses cured him. (Wu Tianshi)
A man contracted Wind-Damp, developing Bai Hu Li Jie Feng (White Tiger Joint Pain). Unilateral twitching pain prevented walking for three years; hundreds of treatments failed. One night, he dreamed of receiving Mutong Tang. He took two liang of Tong Cao (Mutong), decocted in running water. After one hour, severe itching occurred, upper body developed red bean-sized rashes, sweating down to waist, and upper body pain ceased. Next day, same dose caused lower body rash/sweating to feet, leaving whole body comfortable. After one month, strength returned, gait normal. Treated several others successfully. "Pain implies blockage; unblocked implies no pain." (From *Zheng Zhi Zhun Sheng*)
A Hunan merchant bedridden with wind-disease could still trade/write. A medicine seller crowded the door, annoying the merchant who ordered him away. The seller said: Don't drive me away; I will cure your foot disease. Merchant endured. Asked: How long paralyzed? Seller: Three years. Pain? Seller: Twitching pain in rainy weather. Seller instructed scraping two qian of mule hoof sole skin, washing/frying/grinding, mixing with one qian fried Ru Xiang, dividing into three doses taken with wine. After three days, merchant could get up/walk. Another dose cured him. Jiang Sixing witnessed this and asked: Does any book mention mule hooves for wind-disease? I said: No. Asked about speed: Mules/horses excel at walking/driving away Wind; power lies in hooves. Added Ru Xiang and wine enhance speed. E-jiao comes from mule hide and drives away Wind; surely hooves work. Though outside standard formularies, it aligns with principle. Recorded to broaden knowledge. (Xu Xuanzhi)
Appendix: Numbness
Ma (Numbness) is like Bi; though pain/itch are unknown, slight Qi flow is felt. Mu (Woodiness) means not only unknown pain/itch, but no Qi flow perceived. (From *Yi Xue Ru Men*)
Numbness results from sluggish Ying/Wei circulation and stagnant meridians. Common in hands/feet because meridians originate at finger/toe tips, traveling far where Qi/Blood rarely reach. Do not mistake for Wind treatment. (From *Zheng Hui Hui Bu*)
Everyone knows numbness is Wind. Careful analysis shows distinction: Sitting long causes numbness; being tied causes numbness. This is not Wind, but Qi stagnation. Promote Qi flow, and numbness vanishes. (Li Dongyuan)
Ma is Qi deficiency; Mu is Damp-Phlegm and Dead Blood. Ma/Mu divide "Bu Ren" (Insensitivity) into two. Sometimes Qi/Blood dual deficiency causes only Ma; sometimes deficiency with Dampness causes both Ma and Mu; sometimes deficiency allows Wind/Cold/Damp invasion causing whole-body twitching pain and numbness, called Zhou Bi. Treat by sweating first, then tonifying, applying logic analogously. (Zhu Danxi)
Appendix: Itching
All pain, itching, and sores belong to Heart Fire. (From *Su Wen*)
Pain is Yin; Itch is Yang. Liver Channel deficiency causes sudden itching; Ren Mai deficiency causes scratching itch. (From *Ling Shu*)
Approaching fire: Mild heat causes itch; severe heat causes pain; close contact causes burning sores. All are effects of Fire. Itch is a "beautiful illness"; Fire peaks in Summer, making things flourish. Burning/moistening increases itch due to heat. Resolving itch via heat relaxes skin, opens cou li, vents Yang, and dissipates heat. Summer heat itch resistant to cold water: Cold contracts and closes cou li, trapping Yang Qi, causing internal stifling heat. Scratching relieves itch because itch transforms via Fire; scratching makes skin pungent (Metal nature); Pungency disperses, so Metal transformation breaks down Fire. Some say pain is Excess, itch is Deficiency; this doesn't mean Deficiency is Cold, but refers to degrees of Heat. (Liu Hejian)
All itching is Deficiency; Blood fails to nourish muscle/cou li, causing itch. Use tonifying herbs to nourish Yin/Blood. When Blood harmonizes and skin moistens, itch ceases. (From *Dan Xi Xin Fa*)
