窦材治一人，病半身不遂，先灸关元五百壮，一日二服八仙丹，五日一服换骨丹，觉患处汗出，来日病减
四分，一月全愈。再服延寿丹半斤，保元丹一斤，五十年病不作。《千金》等方不灸关元，不服丹药，惟以寻常
药治之，虽愈难久。
一人患左半身不遂，六脉沉细无力。窦曰∶此必服峻利之药，损其真气，故脉沉细。病者云∶前月服捉虎
丹，吐涎二升，此后稍轻，但未全愈耳。窦叹曰∶中风本因元气虚损，今服吐剂，反伤元气，目下虽减，不数
日再作，不复救矣。不十日果大反，复求治，虽服丹药竟不能起。
余尝行衡州道中，遇醴陵尉自衡阳方回，以病归。问其得疾之由，曰∶某食猪肉，入山既深，无肉可以
食，偶从者食穿山甲肉，因尝数脔，旧有风疾，至是复作，今左手足废矣。因以箧中风药遗之，后半月闻其人
顿愈。及至永州，观《图经》曰∶穿山甲不可杀于堤岸，血一入土，则堤岸不可复塞，盖能透地脉也。如此尉
因误食致病，而旬日痼疾尽愈，亦可怪也。今人用以通妇人脉甚验。
万 家贫，拆字度日，得末疾以帛络臂于项，左手执杖而行，服药不效。一日遇吕纯阳，谓曰∶汝少饶今
涩，怒盛于肝，以致生火，其如雷击风旋。二气不合，是以火不生土而土焦，土不生金而金铄，金不克木，木
反克之。子孙拂意，方致汝蹶，血气停滞于脉络，乃致如此。因以手扪腰臂，曰∶酸乎？曰∶不。又再扪至膝。
曰∶酸矣。曰∶此乃环跳穴所在，汝既知酸，他日将弃此杖矣。又见 手有悬帛，又将手向衣内上下扪者三。
曰∶幸瘦，可愈。汝五脏俱火，不必饵药，惟武夷茶能解之，茶以东南枝者佳，采得烹以涧泉，则茶竖立，若
以井水则横。还居数日，忽不知手举足步矣。（《续金陵琐事》。雄按∶茶专清肃肺金。）
李时珍治一人偏风，手足不举，用蓖麻油同羊脂、麝香、鲮鲤甲（即穿山甲。）等药，煎作摩膏，日摩数次，一
月余渐复，兼服搜风化痰养血之剂，三月而愈。又一人病手臂一块肿痛，亦用蓖麻捣膏贴之，一夜而愈。（《本草
纲目》。外治法甚佳，不可不知。）
薛立斋治一妇人，性善怒，常自汗，月经先期，以为肝火血热，不信，乃泛用降火之剂，反致月经过期。
复因劳怒，口噤呻吟，肢体不遂，六脉洪大，面目赤色，用八珍、麦冬、五味、山栀、丹皮，数剂渐愈。兼用
逍遥、六味丸各三十余剂全愈。
一妇人因怒患痰厥而苏，左手臂不能伸，手指麻木，口 眼斜，痰气上攻，两腿骨热，或骨中酸痛，服乌
药顺气散之类，诸症益甚，不时昏愦，更加内热晡热，此肝经血虚，内热生风，前药复耗肝血，虚火炽盛而益
甚也。先以柴胡栀子散，调养肝经气血。数日后用八珍汤加钩藤钩散，诸症稍愈。又用加减八味丸料，少加酒
炒黄柏、知母黑色者，数剂诸症顿退。乃服八珍、柴胡栀子散，半载而痊。后劳役即有复作之意，服柴胡栀子
散遂安。
至正十二年某月，括苍叶仲刚氏，居天台郡为府史且三岁。一日病肢体不随，众医皆以为洞风，谓风洞彻
四肢也。疗之不能愈，请于施敬仲。敬仲诊其脉曰∶病积于身有日矣，为大剂饮之，不旬日遂愈。人咸神异其
故。敬仲曰∶某所以知仲刚病者，切其脉大而来徐，是积热盘郁于内，久不得发，卒与风遇，其病当作，吾以
脉治之而愈，何神异焉？（白云集《医说续编》。）
王肯堂治一人，右手足偏废，不起床三年矣，久服顺气行痰之药不效。至夜神志辄昏，度不可支，服十全
大补即觉清明，数日能扶策而起，无何能舍策而步矣。经云∶邪之所凑，其气必虚。但治其虚，不理其邪，而
邪自去也。
此等语最误后人。此人因多服顺气化痰药，致虚本元，故以十全大补取效。若不论邪之有无，但以纯补
为祛邪妙法，则大谬矣。
李东垣治陕帅郭巨济病偏枯，二指着足底不能伸，以长针刺委中，深至骨而不知痛，出血一二升，其色如
墨。又且缪刺之，如是者六七次，服药三月，病良愈。（《试效方》。）
冯楚瞻治于某患偏枯症，右臂浮肿，或麻或痛，难于步履。或者谓痰、谓火、谓风，多与清凉消克发散之
剂。一日忽昏迷不省，痰喘溃汗，脉之六部沉微。此中气久虚，不为峻补，反肆克伐，非重剂无以挽回。乃用
人参六两，炒黄白术四两，生附子一枚，去皮，姜汁炒，水煎一碗灌之，汗渐收，脉渐起，痰喘定而神清，调
补一月而愈。
吴孚先治王季衡，患左半身不遂。或作痛风与发散，或作痰治与滚痰丸，下数行，精神困惫。左部沉细而
弱，此非湿痰死血，乃血虚也。左属血，然非气以统之则不流，法当从阳引阴。上午用四君子汤加黄 、桂枝、
首乌、制附，下午用四物汤加秦艽、续断、炮姜，并加新绛少许，取丝有棉棉不绝之形，绛有入心化赤之义
也，治左半身不遂尤宜用之。四十帖，手能运动。倍之，足能步履如初。（近时吴门专以此法，欣动愚昧。）
韩贻丰治孔学使尚先，患半身不遂，步履艰难，语言謇涩，音含糊，气断续，为针环跳、风市、三里各二
十一针，即下床自走，不烦扶掖，筋舒血活，无复病楚，意惟语言声音如旧。翌日又为针天突、膻中十四针，
遂吐音措词，琅然条贯矣。
穆大司农和伦，先是左手患木风，指不能伸屈，此半身不遂之兆也。召韩治，为用七针，指即伸缩无恙。
逾两月，复患腿疾，必恃杖而行，因力辞乞休，已而韩为针环跳、风市、三里，针数次而疾顿瘳，遂视事如故。
喻嘉言治季蘅翁，年将七旬，半身不遂已二载，病发左半口往右 ，昏厥遗尿。初服参、 颇当，惑于左
半属血，不宜补气之说，几至大坏。云间施笠泽以参、附疗之稍安。然概从温补，未尽病情也。脉之软滑中时
带劲疾，盖痰与风杂合之症，痰为主，风为标也。又热与寒杂合之症，热为主，寒为标也。平时手冷如冰，故
痰动易厥，厥已复苏，呕去其痰，眠食自若。冬月颇能耐寒，可知寒为外显之假寒，热为内蕴之真热。热蒸湿
以为痰，阻塞窍隧，故卫气不周，外风易入。加以房帏不节，精气内虚，与风相召，是以杂合而成是症耳。今
欲大理右半脾胃之气，以运出左半之热痰虚风，要非温补一端所能尽也。夫治杂合之病，必须用杂合之药，而
随时令以尽无穷之变。如冬月严寒，身内之热为寒所束，不得从皮肤外泄，势必深入筋骨为害矣。故用姜、附
以暂撤外寒，而内热反得宣泄。若时令之热与内蕴之热相合，复助以姜、附，三热交煽，有灼筋腐肉而已。
夫左右者，阴阳之道路，故肝胆居左，而其气常行于右，脾胃居右，而其气常行于左，往来灌注，是以生生不
息也。肝木主风，脾湿为痰，风与痰之中人，原不分于左右。但翁过损精血，是以八八天癸已尽之后，左半先
亏，而右半饮食所生之痰，与皮毛所入之风，以渐积于空虚之府，而骤发始觉耳。风脉劲疾，痰脉软滑，故病
则大筋短缩，即舌筋亦短而謇于言。小筋弛长，故从左而 于右，是可知左畔之小筋弛而不张矣。若左筋之张，
则左矣。凡治一偏之风，法宜从阴引阳，从阳引阴，从左引右，从右引左。以参、术为君臣，以附子、干姜为
佐使，寒月可恃无恐。以参、术为君臣，以羚羊、柴胡、知母、石膏为佐使，而春夏秋三时可无热病之累。然
宜刺手足四末，以泄荣血而通气，恐热痰虚风久而成疠也。门人问曰∶半身不遂之病，原有左右之分，岂左右
分属之后，病遂一往不返乎？若答曰∶风与痰之中人，各随所造，初无定体。病成之后，亦非一往不返也。盖
有往有复者天运、人事、病机，无不皆然。如风者，四时八方之气，从鼻而入，天之气也。痰者，五谷百物之
味，从口而入，脾胃之湿所结，地之气也。势本相辽，亦尝相兼，全似内伤之与外感，每挟杂而易眩。故风胜
者，先治其风；痰胜者，先治其痰；相等则治风兼治痰，此定法也。《内经》曰∶风之中人也，先从皮毛而入，
次传肌肉，次传筋脉，次传骨髓。故善治者，先治皮毛，其次治肌肉。由此观之，乃从右而渐入于左也。皮毛
者，肺主之；肌肉者，胃主之；筋脉者，肝主之；骨髓者，肾主之。从外入者，转入转深，故治皮毛治肌肉，
不使其深入也。又曰∶湿之中人也，先从足始，此则自下而之上，无分于左右者也。但内风素胜之人，偏与外
风相召；内湿素盛之人，偏与外湿相召。内风之人，大块之噫气未动，而身已先惕；内湿之人，室中之础磉
未润，而体已先重。是以治病必从其类也。从外入者，以渐而驱之于外；从下上者，以渐而驱之于下。如治风
用大小续命汤，方中桂、附、苓、术、麻黄，表里庞杂，今人见为难用，不知用桂、附所以驱在里之邪，用苓、
术所以驱在中之邪，用麻、防等表药独重者，正欲使内邪从外而出也。至于病久体虚，风入已深，又有一气微
汗之法，一旬微利之法，平调半月十日，又微微驱散，古人原有规则。若任其一往不返，安贵其为治乎？至于
治痰之规则，不见于方书。如在上者，用瓜蒂散、栀豉汤等方。在左者，用龙荟丸。在右者，用滚痰丸。以及
虚人用竹沥达痰丸，沉寒锢冷用三建汤之类，全无奥义。吾今为子明之，盖胃为水谷之海，五脏六腑之总司，
人之饮食太过而结为痰涎者，每随脾之健运而渗灌于经隧，其间往反之机如海潮然，脾气行则潮去，脾气止则
潮回。所以治沉锢之法，但取辛热微动寒凝，以后止而不用，恐脾得热而过动，痰得热而妄行，为害不浅也。
人身之痰既由胃以流于经隧，则经隧之痰亦必返之于胃，然后可从口而上越，从肠而下达。此惟脾气静息之时，
其痰可返。故凡有痰症者，早食午食而外，但宜休养脾气不动，使经隧之痰，得以返之于胃，而从胃之气上下，
不从脾之气四迄，乃为善也。试观人痰病轻者，夜间安卧，次早即能吐出泄出。痰病重者，昏迷复醒，反能呕
出泄出者，岂非未曾得食，脾气静息，而予痰以出路耶？从来服峻补之药者，深夜亦欲得食，人不知其故，反
以能食为庆，不知爱惜脾气，令其昼运夜息，乃可有常，肯因俚言而三思否？（雄按∶戚鹤泉云∶左阳位东
南，右阴位西北，天有余于阳，故不满西北，而人身头以上应天，左耳目常明于右。其感于邪也，必右甚于左。
地有余于阴，不足于阳，故不满东南，而人身头以下应地，右手足常便于左。其感于邪也，必左甚于右，所
谓邪乘虚而入也。在上右甚，虚在血。在下，下左甚，虚在气。凡半身不遂，头面无过者，当以左阳
右阴。地道右强于左之义权之，如病在左，此自阳不足而然为顺。如反病在右，而阴血大亏，并其有余者损之，病
为逆也。左阳右阴为天地定理，不得肝位左为主血，肺位右为主气，遂以左为血病，右为气病，错阴阳之道路也。
更推言之，则男子法乎天，女子法乎地。天道左盛，男上病不可在左。若身以下属地道，则东南阳常不足，
左病非逆也。地道右盛，女下病不宜在右。若身以上属天道，则西北阴常不足，右病非逆也。）
朱丹溪治一肥人，忧思气郁，右手瘫，口 ，与补中益气汤。有痰加半夏、竹沥、姜汁，煎服。
程云来曰∶里中一老医，右手足废，不能起于床者二年矣。忽遇诸涂，询之曰∶吾之病几危，始服顺气行
痰之剂了无应，薄暮则神志辄昏，度不可支，令家人煎进十全大补汤，即觉清明，遂日服之，浃数月能杖而起，
无何则又能舍杖而步矣。经云，邪之所凑，其气必虚。吾治其虚，不理其邪，而邪自去，吾所以获全也。余曰∶
有是哉？使进顺气疏风之剂不辍者，墓木拱矣。然此犹拘于成方，不能因病变通，随时消息，故奏功稍迟。使
吾为之，当不止是也。（程云来《医眼卮言》。 ）
据程说只用大剂人参，有痰者宜竹沥，少加姜汁佐之。其用四物、二陈、胆星、天麻者大谬。
俞东扶曰∶偏枯之症，昔人谓左属血虚，右属气虚，自得喻氏之论，其理始明。而随时换药及刺四末，尤

又云，风雨寒热，不得虚，邪不能独伤人。又曰，虚邪之风，与其身形两虚相得，乃客其形，是确指虚人而后

窦材治疗一个人，患半身不遂（中风后一侧肢体瘫痪），先艾灸关元穴五百壮，每天服用两次八仙丹，每五天服用一次换骨丹，感觉患处出汗，第二天病情减轻四分之一的程度，一个月后完全痊愈。再服用半斤延寿丹、一斤保元丹，五十年内疾病不再发作。《千金方》等医方不灸关元穴，不服用丹药，只用寻常药物治疗，虽然能治愈但难以长久维持。
另有一人患左半身不遂，六部脉象沉细无力。窦材说：“这一定是服用了峻烈通利之药，损伤了真气，所以脉象沉细。”病人说：“上个月服用了捉虎丹，吐出涎液二升，此后症状稍轻，但未完全痊愈。”窦材叹息道：“中风本来是因为元气虚损，现在服用催吐剂，反而进一步损伤元气，眼下虽然症状减轻，但不出几天就会复发，到时候就无法救治了。”果然不到十天病情大加重，再次求治，虽然服用了丹药最终也没能挽回生命。
我曾经行走在衡州道上，遇到醴陵县尉从衡阳刚回来，因病返乡。询问他得病的原因，他说：“我吃了猪肉，进山很深，没有肉可以吃，偶然随从吃了穿山甲的肉，我也尝了几块，旧有的风疾因此复发，现在左手脚废用了。”于是我把箱子里的风药送给他，后来半个月听说那人顿时痊愈。到了永州，观看《图经》记载说：“穿山甲不能在堤岸上杀，它的血一旦进入泥土，堤岸就无法再堵塞，因为它能穿透地脉。”像这位县尉因为误食致病，而十天内陈年痼疾全部痊愈，也很奇怪。现在人们用它来通妇人经脉非常有效。
万家生活贫困，靠拆字算命度日，得了末疾（四肢病变），用帛带将手臂挂在脖子上，左手拄杖行走，服药无效。一天遇到吕纯阳，对他说：“你今年运势涩滞，肝火旺盛，导致生火，如雷击风旋般剧烈。阴阳二气不合，所以火不生土而土焦，土不生金而金销，金不能克木，木反而反克。子孙不如意，才导致你跌倒，血气停滞在脉络中，才造成这样。”于是用手抚摸他的腰臂，问：“酸吗？”回答说：“不。”又摸到膝盖，问：“酸了吗？”回答说：“酸了。”吕纯阳说：“这就是环跳穴所在的位置，既然你知道酸，将来你会扔掉这根拐杖的。”又看到万家手上有悬着的帛带，又把手伸进衣服里上下摸索三次，说：“幸好消瘦，可以痊愈。你五脏都有火，不必吃药，只有武夷茶能解它，茶以东南枝为佳，采来用山涧泉水烹煮，茶叶会竖立，如果用井水则横卧。回家住几天后，忽然不知不觉手能举、脚能走了。”（出自《续金陵琐事》。徐灵胎按语：茶专门清肃肺金。）
李时珍治疗一个偏风患者，手足不能抬起，用蓖麻油同羊脂、麝香、鲮鲤甲（即穿山甲）等药，煎制成按摩膏，每天按摩数次，一个多月逐渐恢复，同时服用搜风化痰养血的药剂，三个月痊愈。又有一人手臂某处肿痛，也用蓖麻捣成膏贴敷，一夜痊愈。（出自《本草纲目》。外治法非常好，不可不知道。）
薛立斋治疗一个妇人，性格易怒，经常自汗，月经提前，认为是肝火血热，病人不信，于是泛用降火药物，反而导致月经延期。后来又因劳累和愤怒，出现口噤呻吟，肢体不遂，六脉洪大，面目赤红，使用八珍汤、麦冬、五味子、山栀、丹皮，几剂后逐渐好转。兼用逍遥散、六味地黄丸各三十多剂，完全痊愈。
另一个妇人因愤怒患痰厥苏醒后，左手臂不能伸展，手指麻木，口眼歪斜，痰气上攻，两腿骨头发热，或骨中酸痛，服用乌药顺气散之类的药物，各种症状更加严重，不时昏愦，加上内热和傍晚潮热，这是肝经血虚，内热生风，前面的药物又耗伤肝血，虚火炽盛而更加严重。先用柴胡栀子散，调养肝经气血。几天后用八珍汤加钩藤散，各种症状稍好。又用加减八味丸料，少加酒炒黄柏、知母（黑色者），几剂后各种症状顿时消退。于是服用八珍汤、柴胡栀子散，半年后痊愈。后来因劳累又有复发迹象，服用柴胡栀子散便安定下来。
至正十二年某月，括苍人叶仲刚氏，在天台县做府史已经三年。一天患病肢体不受控制，众医生都认为是洞风（风邪深入四肢），认为风邪洞彻四肢。治疗不能痊愈，请求施敬仲诊治。施敬仲诊其脉说：“病积聚在身上有日子了，用大剂量药剂服用，不到十天就痊愈了。”人们都认为此事神奇怪异。施敬仲说：“我之所以知道叶仲刚的病，切脉发现脉象大而来势缓慢，是积热郁结在体内，很久不能发散，突然遇到风邪，病就要发作，我用脉象诊断并治疗而痊愈，有什么神奇的呢？”（出自白云集《医说续编》。）
王肯堂治疗一个人，右手足偏废，卧床不起三年了，长期服用顺气行痰的药物无效。到了晚上神志就昏沉，估计无法支撑，服用十全大补汤后就觉得清醒，几天后能扶着拐杖起来，不久就能扔掉拐杖走路了。《内经》说：“邪气聚集的地方，正气必然虚弱。”只要治疗其虚证，不理会邪气，邪气自然去除。
这些话最误导后人。这个人因为多服顺气化痰药，导致本元虚损，所以用十全大补汤取得疗效。如果不分邪气有无，只把纯补作为祛邪的妙法，那就大错特错了。
李东垣治疗陕帅郭巨济患偏枯症，两个脚趾着地不能伸展，用长针刺委中穴，深至骨部而不觉得痛，出血一二升，颜色如墨。又采用缪刺法，如此进行六七次，服药三个月，病基本痊愈。（出自《试效方》。）
冯楚瞻治疗于某患偏枯症，右臂浮肿，有时麻木有时疼痛，难以行走。有人说是痰、说是火、说是风，多用清凉消克发散的药剂。一天忽然昏迷不省人事，痰喘大汗，诊脉六部沉微。这是中气久虚，不进行峻补，反而大肆攻伐，不用重剂无法挽回。于是用人参六两，炒黄白术四两，生附子一枚，去皮，姜汁炒，水煎一碗灌服，汗渐渐收敛，脉象渐渐起，痰喘停止而神志清醒，调理补益一个月而痊愈。
吴孚先治疗王季衡，患左半身不遂。有人当作痛风用发散法，有人当作痰用滚痰丸，下泻几次后，精神困倦疲惫。左部脉沉细而弱，这不是湿痰死血，而是血虚。左侧属血，然而没有气来统摄就不能流动，治法应当从阳引阴。上午用四君子汤加黄芪、桂枝、首乌、制附子，下午用四物汤加秦艽、续断、炮姜，并加少许新绛，取丝线绵延不绝的形状，绛色有入心化赤的意义，治疗左半身不遂尤其适宜使用。四十帖后，手能运动。加倍剂量，脚能像以前一样行走。（近来吴门地区专门用这种方法，欣喜地动摇了我的愚见。）
韩贻丰治疗孔学使尚先，患半身不遂，步履艰难，语言謇涩，声音含糊，气息断续，为他针刺环跳、风市、足三里各二十一针，随即下床自己走，不需要搀扶，筋舒血活，不再有病痛，只是语言和声音还像以前一样。第二天又为他针刺天突、膻中十四针，于是吐词清晰，条理分明。
穆大司农和伦，先是左手患木风（麻木之风），手指不能伸缩，这是半身不遂的先兆。请韩贻丰治疗，用了七针，手指立即伸缩正常。过了两个月，又患腿疾，必须依靠拐杖行走，于是极力推辞请求退休，不久韩贻丰为他针刺环跳、风市、足三里，针刺几次后疾病顿时减轻，于是像以前一样处理公务。
喻嘉言治疗季蘅翁，年纪将近七十岁，半身不遂已经两年，发病时左半边身体僵硬向右歪斜，昏厥遗尿。起初服用人参、附子很对症，但被“左半属血，不宜补气”的说法迷惑，几乎导致病情恶化。云间施笠泽用人参、附子治疗稍微安稳。然而一概从温补入手，没有穷尽病情的全貌。脉象软滑中时而带有劲疾，这是痰与风杂合的病症，痰为主，风为标。又是热与寒杂合的病症，热为主，寒为标。平时手脚冷如冰，所以痰动容易厥逆，厥逆苏醒后，呕吐出痰液，睡眠饮食恢复正常。冬天颇能耐寒，可知寒是外显的假寒，热是内蕴的真热。热蒸腾湿气形成痰，阻塞窍隧，所以卫气不周遍，外风容易侵入。加上房事不节制，精气内虚，与风相召，所以杂合而成这个病症。现在想要大力调理右半脾胃之气，以运出左半的热痰虚风，绝非单纯温补一端所能穷尽。治疗杂合的病，必须用杂合的药，并根据时令变化以应对无穷的变化。比如冬天严寒，体内的热被寒所束缚，不能从皮肤外泄，势必深入筋骨为害。所以用姜、附暂时撤除外寒，而内热反而得以宣泄。如果时令的热与内蕴的热相合，再辅助姜、附，三热交煽，只会灼伤筋络腐坏肌肉罢了。
左右，是阴阳的道路，所以肝胆居左，但其气常行于右；脾胃居右，但其气常行于左，往来灌注，所以生生不息。肝木主风，脾湿为痰，风与痰中人，原本不分左右。但老人过度损耗精血，所以在八八六十四岁天癸已尽之后，左半先亏，而右半饮食所生的痰，与皮毛所入的风，逐渐积聚在空虚的脏腑，突然发作才发觉。风脉劲疾，痰脉软滑，所以生病时大筋短缩，就连舌筋也短而言语謇涩。小筋弛长，所以从左歪向右边，可知左边的小筋弛缓而不紧张。如果左边的筋能紧张，左边就正常了。凡治疗偏侧的风，治法宜从阴引阳，从阳引阴，从左引右，从右引左。以人参、白术为君臣，以附子、干姜为佐使，寒冬月份可以无所畏惧。以人参、白术为君臣，以羚羊角、柴胡、知母、石膏为佐使，春夏秋三季可以避免热病的困扰。但应该针刺手足四末，以泄营血而通气，恐怕热痰虚风久了会变成疠病。门人问：“半身不遂的病，原本有左右之分，难道分左右归属之后，病就一去不复返了吗？”回答：“风与痰中人，各自随着造作不同，初无定体。病形成之后，也不是一去不复返的。大概有往有复是天运、人事、病机，无不皆然。比如风，是四时八方之气，从鼻而入，属于天之气。痰，是五谷百物的味道，从口而入，是脾胃之湿所结，属于地之气。形势本来相隔辽远，但也曾相兼，全似内伤与外感，常常夹杂而容易混淆。所以风胜者，先治其风；痰胜者，先治其痰；相等则治风兼治痰，这是定法。《内经》说：‘风之中人也，先从皮毛而入，次传肌肉，次传筋脉，次传骨髓。’所以善于治病的人，先治皮毛，其次治肌肉。由此看来，是从右渐入于左。皮毛由肺主，肌肉由胃主，筋脉由肝主，骨髓由肾主。从外入者，转入转深，所以治皮毛治肌肉，不让它深入。又说：‘湿之中人也，先从足始。’这是自下而上，不分左右。但内风素来旺盛的人，偏与外风相召；内湿素来旺盛的人，偏与外湿相召。内风之人，大地噫气未动，身体已先惊惕；内湿之人，室内柱础未润，身体已先沉重。所以治病必从其类。从外入者，逐渐驱之于外；从下上者，逐渐驱之于下。比如治风用大小续命汤，方中桂、附、苓、术、麻黄，表里庞杂，今人见为难用，不知用桂、附所以驱除在里的邪气，用苓、术所以驱除在中的邪气，用麻、防等表药独重，正是想让内邪从外而出。至于病久体虚，风入已深，又有一气微汗之法，一旬微利之法，平调半月十日，又微微驱散，古人原有规则。如果任由其一去不复返，哪里还贵在有治疗呢？至于治痰的规则，不见于方书。比如在上的，用瓜蒂散、栀豉汤等方。在左的，用龙荟丸。在右的，用滚痰丸。以及虚人用竹沥达痰丸，沉寒锢冷用三建汤之类，全无奥义。我现在为你阐明，胃是水谷之海，五脏六腑的总司，人的饮食太过而结为痰涎的，往往随着脾的健运而渗灌于经隧，其间往反的机制如海潮一般，脾气行则潮去，脾气止则潮回。所以治沉锢的方法，只取辛热微动寒凝，过后停止不用，恐怕脾得热而过动，痰得热而妄行，为害不浅。人身之痰既然由胃流于经隧，那么经隧之痰也必须返之于胃，然后可从口而上越，从肠而下达。这只有在脾气静息之时，其痰才可返还。所以凡有痰症者，早食午食之外，只宜休养脾气不动，使经隧之痰得以返之于胃，而从胃之气上下，不从脾之气四布，这才是好的。试看人痰病轻的，夜间安卧，次日早晨就能吐出泄出。痰病重的，昏迷复醒，反而能呕出泄出的，岂不是未曾进食，脾气静息，给予痰出路吗？从来服用峻补药的人，深夜也想进食，人们不知道原因，反而以能食为庆，不知道爱惜脾气，让它昼运夜息，才能有常，肯因俗语而三思吗？”（徐灵胎按语：戚鹤泉说：左为阳位东南，右为阴位西北，天有余于阳，所以不满西北，而人身头以上应天，左耳目常明于右。感受邪气，必定右边重于左边。地有余于阴，不足于阳，所以不满东南，而人身头以下应地，右手足常便于左。感受邪气，必定左边重于右边，所谓邪乘虚而入。在上部右边重，虚在血。在下部左边重，虚在气。凡半身不遂，头面无碍的，应当以左阳右阴、地道右强于左的道理权衡。如病在左，这是自阳不足所致，为顺。如反病在右，而阴血大亏，并损害其有余者，病为逆。左阳右阴是天地定理，不能因为肝位左主血，肺位右主气，就以左为血病，右为气病，错乱了阴阳的道路。更推而言之，男子法乎天，女子法乎地。天道左盛，男子上病不可在左。若身以下属地道，则东南阳常不足，左病非逆。地道右盛，女子下病不宜在右。若身以上属天道，则西北阴常不足，右病非逆。）
朱丹溪治疗一个肥胖的人，忧思气郁，右手瘫，口眼歪斜，给予补中益气汤。有痰加半夏、竹沥、姜汁，煎服。
程云来说：“乡里一位老医生，右手足废用，不能起床两年了。忽然在路上遇到，问他：‘我的病几乎危及生命，开始服用顺气行痰的药物毫无反应，傍晚神志就昏沉，估计无法支撑，让家人煎服十全大补汤，就觉得清醒，于是每天服用，过了几个月能拄杖而起，不久又能扔掉拐杖走路了。《内经》说，邪气聚集的地方，正气必然虚弱。我治疗其虚，不理会邪气，邪气自然去除，所以我得以保全。’我说：‘有这样的事吗？如果继续服用顺气疏风的药物不停止，坟上的树都长高了。’然而这还是拘泥于成方，不能因病变通，随时斟酌，所以奏效稍慢。如果我治疗，应当不止于此。”（程云来《医眼卮言》。）
根据程的说法，只用大剂人参，有痰者宜用竹沥，少加姜汁佐助。那些用四物、二陈、胆星、天麻的人大错特错。
俞东扶说：“偏枯之症，前人谓左属血虚，右属气虚，自从得到喻氏的论述，道理才明白。而且随时换药及针刺四末，尤其见巧妙。想起小时候读《内经·生气通天论》说，风，是百病之始，清净则肉腠闭拒，即使有大风苛毒，也不能伤害。又说，风雨寒热，不得虚，邪不能单独伤人。又说，虚邪之风，与其身形两虚相得，乃客其形，这是确切指出虚人而后中于虚风。然而这还是因虚受风，所以《灵枢》又有真气去，邪气独留，发为偏枯的说法。偏枯难疗，这两句话概括了。再读通评虚实论说，凡治消瘅扑击（扑击者，如人被击而扑倒，即现在的卒倒），偏枯痿厥，气满发逆，肥贵人则是膏粱之疾。这条暗中包涵痰饮湿热，阴虚阳虚诸候，未曾偏中于邪风。大概肥贵人自然谨慎避开邪风，而膏粱之变，风从内生，刘、李、朱三家从此悟入。大凡治病必求于本，击扑偏枯，以虚为本。再读刘宗浓《玉机微义》和王宇泰《灵兰要览》两书，更加相信塞外多真中，江南多类中。直到缪仲淳立论，谓真阴亏而多热，甚者煎熬津液，”
Dou Cai treated a patient suffering from hemiplegia (paralysis of one side of the body). He first moxibusted the Guanyuan (CV-4) acupoint 500 moxa cones, administered Baxian Dan (Eight Immortals Pill) twice daily, and Hangu Dan (Bone-Replacing Pill) once every five days. The patient sweated at the affected site, and the next day his condition improved by four-tenths. After one month, he was completely cured. He then took half a jin of Yanshou Dan (Longevity Pill) and one jin of Baoyuan Dan (Origin-Sustaining Pill), and the disease did not recur for fifty years. Formulas such as those in *Qianjin Fang* do not moxibust Guanyuan or administer mineral pills, relying only on ordinary medicines. Although they may achieve a cure, it is difficult to maintain long-term health.
Another patient suffered from left-sided hemiplegia with deep, fine, and forceless pulses in all six positions. Dou Cai said, "This must be due to the consumption of harsh and purgative medicines, which damaged the True Qi, hence the deep and fine pulse." The patient replied, "Last month I took Zhuohu Dan (Tiger-Catching Pill) and vomited two sheng of saliva; since then, my symptoms have slightly lightened, but I am not fully recovered." Dou Cai sighed and said, "Stroke is originally caused by deficiency and damage of Yuan Qi. Now, taking emetics further damages the Yuan Qi. Although symptoms are reduced now, it will relapse in a few days, and there will be no way to save him." Indeed, within ten days, the condition severely worsened. Despite seeking treatment again and taking mineral pills, he could not be saved.
Once, while traveling through Hengzhou, I met the Magistrate of Liling returning from Hengyang, ill and retiring due to sickness. Asking about the cause, he said, "I had pork, but went deep into the mountains where no meat was available. My attendants ate Pangolin meat, so I tasted several pieces. I had a history of wind disease, which recurred then, leaving my left hand and foot paralyzed." I gave him some wind-dispelling medicine from my chest, and heard half a month later that he had suddenly recovered. Upon reaching Yongzhou, I read in *Tu Jing* that "Pangolins should not be killed on embankments; if their blood enters the soil, the embankment cannot be sealed again, as they can penetrate the earth's veins." It is strange that this magistrate fell ill from accidentally eating pangolin meat, yet his chronic illness was cured in ten days. Nowadays, people use it to unblock women's menstruation with great efficacy.
Wan Jia was poor, making a living by fortune-telling with characters. He suffered from limb disease, tying his arm with silk around his neck and walking with a cane in his left hand; medicines were ineffective. One day he met Lü Dongbin, who said, "Your current fortune is stagnant. Liver Fire is excessive, generating heat like thunder striking and wind swirling. Yin and Yang Qi are discordant, so Fire does not generate Earth, causing Earth to scorch; Earth does not generate Metal, causing Metal to melt; Metal fails to control Wood, so Wood counter-controls. Displeasure from descendants led to your fall. Blood and Qi stagnated in the meridians, resulting in this." He palpated Wan's waist and arm, asking, "Is it sore?" "No." Palpating down to the knee, he asked again, "Sore now?" "Yes." Lü said, "This is the location of the Huantiao (GB-30) acupoint. Since you feel soreness, you will discard this cane someday." Seeing the silk hanging from Wan's hand and him rubbing inside his clothes three times, Lü said, "Fortunately, you are thin; you can be cured. Your Five Viscera all have Fire. No need for medicine; only Wuyi Tea can resolve it. Tea from branches facing southeast is best. Brew it with spring water from a ravine, and the tea leaves will stand upright; well water makes them lie flat." After staying home for a few days, he suddenly found he could lift his hands and step without knowing how. (From *Xu Jinling Suoshi*. Xu Lingtai notes: Tea specifically clears and descends Lung Metal.)
Li Shizhen treated a patient with hemiplegia whose limbs could not move. He used Castor Oil mixed with Sheep Fat, Musk, and Pangolin Scales (Lin Qi Jia), decocted into a massage ointment, applied several times a day. After over a month, gradual recovery occurred. Concurrently taking formulas to dispel wind, resolve phlegm, and nourish blood, he was cured in three months. Another patient had swelling and pain in an arm area; applying crushed Castor seed paste cured him overnight. (From *Bencao Gangmu*. External treatments are excellent and should not be ignored.)
Xue Lizhai treated a woman prone to anger, with spontaneous sweating and early menstruation, diagnosing Liver Fire and Blood Heat. She disbelieved this and indiscriminately used cooling agents, causing delayed menstruation. Later, due to labor and anger, she developed lockjaw, groaning, paralysis, surging pulses, and red face/eyes. Using Bazhen Tang, Ophiopogon Radix (Maidong), Schisandra Fructus (Wuweizi), Gardenia Fruit (Shanzhi), and Moutan Cortex (Danpi), she gradually improved over several doses. Combined with Xiaoyao San and Liuwei Dihuang Wan (Six-Ingredient Pill with Rehmannia) for over thirty doses each, she fully recovered.
Another woman, after recovering from Phlegm-Jue (syncope due to phlegm) caused by anger, had a left arm unable to extend, numb fingers, facial deviation, attacking phlegm-Qi, hot bones in both legs, or bone ache. Taking Youyao Shunqi San (Aucklandia Powder to Smooth Qi) worsened symptoms, causing frequent fainting, internal heat, and afternoon tidal fever. This indicated Liver Meridian Blood Deficiency, internal heat generating wind; previous medicines consumed Liver Blood, intensifying deficient fire. First, Chaihu Zhizi San (Bupleurum and Gardenia Powder) was used to nourish Liver Qi and Blood. Days later, Bazhen Tang plus Gouteng Teng (Uncaria Ramulus cum Uncis) relieved symptoms. Then, Jiajian Bawei Wan (Modified Eight-Ingredient Pill) with slight amounts of wine-fried Phellodendron Bark (Huangbai) and Anemarrhena Rhizome (Zhimu - black variety) cleared symptoms rapidly. Finally, Bazhen Tang and Chaihu Zhizi San for half a year achieved full recovery. Relapses due to overwork were managed with Chaihu Zhizi San.
In the twelfth year of Zhizheng, Ye Zhonggang from Kuocang served as a prefectural clerk in Tiantai for three years. One day, his limbs became uncontrolled. Physicians diagnosed it as Dongfeng (Wind piercing the limbs), believing wind penetrated all four limbs. Treatment failed. He sought Shi Jingzhong. Shi palpated the pulse and said, "The pathogen has accumulated in the body for a long time. Take large doses, and it will be cured in ten days." People marveled at this. Shi explained, "Palpating the pulse, it was large but slow in arrival, indicating accumulated heat郁结 internally, unable to vent for a long time. Suddenly encountering wind triggered the disease. I treated based on the pulse, hence the cure. What is miraculous about it?" (From Baiyun Ji, *Yishuo Xubian*.)
Wang Kentang treated a patient with right-sided hemiplegia bedridden for three years, unresponsive to Qi-regulating and phlegm-resolving drugs. At night, consciousness would cloud, and survival seemed impossible. Taking Shiquan Dabu Tang (Perfect Ten Great Tonifying Decoction) brought clarity; within days, he could rise with a cane, soon walking without it. The Classic says: "Where evil gathers, Qi must be deficient." Treating the deficiency alone, ignoring the evil, causes the evil to depart naturally.
Such statements mislead later generations. This patient became deficient due to excessive Qi-regulating and phlegm-resolving drugs, so Shiquan Dabu Tang worked. If one assumes pure tonification cures evil regardless of its presence, it is a grave error.
Li Dongyuan treated Governor Guo Juji of Shaanxi with hemiplegia, unable to extend two toes. He inserted a long needle into Weizhong (BL-40) deeply to the bone without pain sensation, draining one to two sheng of dark, ink-like blood. He also applied Miao Ci (Mirror Needling). After six or seven sessions and three months of medication, the disease largely resolved. (From *Shixiao Fang*.)
Feng Chuzhan treated Yu Mou with hemiplegia, swollen right arm, numbness/pain, difficulty walking. Others attributed it to phlegm, fire, or wind, using cooling, draining, and dispersing agents. Suddenly, he became comatose with phlegm-wheezing and profuse sweating; all six pulses were deep and minute. This was chronic Middle Qi deficiency. Without harsh tonification, but instead heavy draining, only heavy doses could reverse it. He used Ren Shen (Ginseng Root) 6 liang, fried Atractylodes Macrocephala Rhizome (Baizhu) 4 liang, raw Aconite Car root (Fuzi) 1 piece (peeled, fried in ginger juice), decocted in water to one bowl and灌ed. Sweat stopped, pulses rose, phlegm-wheezing ceased, consciousness cleared. After one month of regulation and tonification, he recovered.
Wu Fuxian treated Wang Jiheng with left-sided hemiplegia. Some treated it as gout with dispersing methods; others as phlegm with Gun Tan Wan (Rolling Phlegm Pill). After several purgations, spirit was exhausted. Left pulses were deep, fine, and weak. This was not damp-phlegm or dead blood, but Blood Deficiency. The left belongs to Blood, but without Qi to govern it, it does not flow. The method should be "leading Yin from Yang." Morning: Sijunzi Tang (Four Gentlemen Decoction) plus Astragalus Membranaceus Root (Huangqi), Cinnamon Twig (Guizhi), Polygonum Multiflorum Root (Shouwu), processed Aconite (Zhi Fu). Afternoon: Siwu Tang (Four Substances Decoction) plus Gentian Macrophylla Root (Qinjiao), Drynaria Rhizome (Xuduan), roasted Ginger (Pao Jiang), and a little Xinjiang (New Crimson Silk). Silk implies continuity; crimson implies entering the Heart to transform into red blood. This is especially suitable for left hemiplegia. After forty doses, hands moved. Doubling the dose, feet walked normally. (Recently, practitioners in Wu men specialize in this method, which has stirred my humble thoughts.)
Han Yifeng treated Kong Xueshi Shangxian with hemiplegia, difficult walking, slurred speech, hoarse voice, intermittent breath. He needled Huantiao (GB-30), Fengshi (GB-31), and Zusanli (ST-36) twenty-one times each. The patient immediately walked independently without support, tendons relaxed, blood circulated, pain vanished, though speech remained unchanged. The next day, he needled Tiantu (CV-22) and Danzhong (CV-17) fourteen times. Speech became clear and coherent.
Grand Minister Helun initially suffered from numbness in the left hand, inability to flex/extend fingers, a precursor to hemiplegia. Han treated with seven needles, restoring finger movement. Two months later, leg disease required a cane, leading to resignation requests. Han needled Huantiao, Fengshi, and Zusanli several times, quickly alleviating the disease, allowing him to resume duties.
Yu Jiayan treated Ji Hengweng, nearly seventy, with two-year hemiplegia. Attacks involved left-side stiffness tilting right, syncope, and urinary incontinence. Initially, Ginseng and Aconite were appropriate, but confusion over "left belongs to blood, avoid tonifying Qi" nearly ruined him. Shi Lizewen from Yunjian used Ginseng and Aconite to stabilize. However, general warming tonification did not exhaust the pathology. Pulses were soft and slippery, occasionally rapid/tense, indicating mixed Phlegm and Wind (Phlegm primary, Wind secondary), and mixed Heat and Cold (Heat primary, Cold secondary). Hands cold as ice meant Phlegm agitation caused Jue; vomiting Phlegm restored sleep/appetite. Winter tolerance of cold showed external cold was false, internal heat was true. Heat steamed dampness into Phlegm, blocking orifices, disrupting Wei Qi, inviting external wind. Sexual excess depleted Essence/Qi, attracting wind. Thus, mixed pathology arose. To treat, one must vigorously regulate Right/Spleen-Stomach Qi to transport Left/Heat-Phlegm-Deficient-Wind. Pure warming tonification is insufficient. Mixed diseases require mixed medicines adapted to seasons. In winter cold, internal heat is bound, forcing it into sinews/bones. Ginger/Aconite temporarily expel external cold, allowing internal heat to vent. If seasonal heat merges with internal heat, adding Ginger/Aconite causes three heats to flare, burning sinews/flesh.
Left/Right are paths of Yin/Yang. Liver/Gallbladder reside left, but Qi moves right; Spleen/Stomach reside right, but Qi moves left. Liver Wood governs Wind; Spleen Dampness forms Phlegm. Wind/Phlegm attack不分左右. But the elder depleted Essence/Blood; after age 64 (8x8), Tian Gui ended, Left deficit appeared first. Right-side dietary Phlegm and skin-invading Wind accumulated in empty organs, erupting suddenly. Wind pulses are tense/rapid; Phlegm pulses are soft/slippery. Disease shortens large sinews (limb contraction) and tongue sinews (speech impediment). Small sinews relax, pulling left to right. Treating unilateral wind requires "leading Yin from Yang, Yang from Yin, Left from Right, Right from Left." Use Ginseng/Atractylodes as Sovereign/Minister, Aconite/Dried Ginger as Assistant/Envoy in winter. Use Ginseng/Atractylodes with Antelope Horn, Bupleurum, Anemarrhena, Gypsum in Spring/Summer/Autumn to avoid heat. Needle extremities to drain Ying-Blood and unblock Qi, preventing Phlegm/Wind becoming Leprosy. Disciple asked: "Does hemiplegia stay fixed after distinguishing left/right?" Answer: "Wind/Phlegm follow individual constitution, having no fixed form. Post-disease, it is not irreversible. Return follows departure in heaven, human affairs, and pathology. Wind (Qi of 4 seasons/8 directions via nose) is Heaven Qi. Phlegm (taste of grains via mouth, Spleen-Damp knot) is Earth Qi. Though distant, they combine, like Internal Injury and External Contraction. If Wind dominates, treat Wind first; if Phlegm dominates, treat Phlegm first; if equal, treat both. This is fixed law. *Neijing* states: 'Wind enters via skin/hair, then muscle, then sinews, then marrow.' Good physicians treat skin/muscle first to prevent deepening. Skin=Lung; Muscle=Stomach; Sinews=Liver; Marrow=Kidney. From outside to inside, depth increases. Also: 'Dampness enters via feet,' ascending,不分左右. But internal Wind/Damp attracts external counterparts. Internal Wind sufferers tremble before weather changes; Internal Damp sufferers feel heavy before humidity rises. Treat according to category. External pathogens expelled outward; Ascending pathogens expelled downward. For Wind, use Da/Xiao Xuming Tang. Contains Guizhi, Fuzi, Poria, Atractylodes, Ephedra. Complex, but Guizhi/Fuzi drive interior evil; Poria/Atractylodes drive middle evil; heavy Ephedra/Saposhnikovia drive exterior, aiming to expel internal evil outward. For chronic deficiency/deep wind, use mild sweating or mild purgation methods, balanced for 10-15 days, then gentle dispersion. Ancient rules exist. Ignoring them renders treatment useless. For Phlegm, rules are obscure in texts. Upper: Gua Di San, Zhichi Tang. Left: Longhui Wan. Right: Gun Tan Wan. Deficient: Zhuli Datang Wan. Cold-fixed: Sanjian Tang. No mystery. I clarify: Stomach is Sea of Water/Grain, master of Viscera. Excess diet creates Phlegm, transported by Spleen Transport into collaterals, like tides. Spleen moves = tide goes; Spleen stops = tide returns. To treat fixed Phlegm, use pungent-hot to mildly move cold-stagnation, then stop, fearing Spleen overheats and Phlegm wanders harmfully. Phlegm flows Stomach->Collaterals; Collateral Phlegm must return to Stomach to exit via mouth/intestines. This happens when Spleen rests. Thus, between meals, rest Spleen to allow Phlegm return to Stomach for upward/downward movement via Stomach Qi, not Spleen Qi dispersion. Light phlegm patients spit upon waking; severe comatose patients vomit upon waking. Is this because fasting rests Spleen, giving Phlegm an exit? Those on harsh tonics crave food at night. People celebrate appetite, failing to cherish Spleen rhythm (move day, rest night). Will you ponder this proverb?" (Xu Lingtai notes: Qi Hequan says: Left is Yang/Southeast, Right is Yin/Northwest. Heaven surplus Yang, incomplete Northwest; Head corresponds to Heaven, Left senses clearer than Right. Evil attacks Right more. Earth surplus Yin, incomplete Southeast; Lower body corresponds to Earth, Right limbs freer than Left. Evil attacks Left more. Evil enters via deficiency. Upper Right heavy = Blood deficiency. Lower Left heavy = Qi deficiency. For hemiplegia with normal head/face, weigh Left-Yang/Right-Yin and Earth-Right-Stronger-than-Left. Left disease = Yang deficiency (Smooth). Right disease = Yin-Blood deficiency (Rebellious). Left-Yang/Right-Yin is Heavenly Law. Do not confuse Liver-Left-Blood/Lung-Right-Qi with Left-Blood-Disease/Right-Qi-Disease, confusing Yin-Yang paths. Men follow Heaven (Yang strong); upper disease shouldn't be Left. Lower body follows Earth (Southeast Yang insufficient); Left disease not rebellious. Women follow Earth (Yin strong); lower disease shouldn't be Right. Upper body follows Heaven (Northwest Yin insufficient); Right disease not rebellious.)
Zhu Danxi treated a obese man with worry/thought Qi stagnation, right-hand paralysis, facial deviation. Prescribed Buzhong Yiqi Tang. Added Pinellia, Bamboo Sap, Ginger Juice for Phlegm.
Cheng Yunlai stated: "An old doctor in my village had right-side paralysis bedridden for two years. Met him on road, he said: 'My illness nearly killed me. Initial Qi-regulating/phlegm-resolving drugs failed. Evening drowsiness, near death. Family brewed Shiquan Dabu Tang; clarity returned. Daily use allowed rising with cane after months, then walking unaided. *Classic*: 'Where evil gathers, Qi is deficient.' I treated deficiency, ignored evil, evil departed. Hence survival.' I said: 'True? Had he continued Qi-regulating/dispersing drugs, he would be dead. Yet he stuck to fixed formulas, lacking flexibility/adaptation, hence slow result. I would have done better.'" (Cheng Yunlai, *Yiyan Zhiyan*.)
Based on Cheng, only large-dose Ginseng is needed; add Bamboo Sap/Ginger Juice for Phlegm. Using Siwu, Erchen, Danxing, Tianma is grossly wrong.
Yu Dongfu said: "For hemiplegia, ancients said Left=Blood Def, Right=Qi Def. Yu's theory clarified this. Seasonal formula changes and extremity needling are clever. Recalling *Neijing·Shengqi Tongtian Lun*: 'Wind is start of hundred diseases... even great wind/toxin cannot harm if flesh/pores are closed.' Also: 'Wind/Rain/Cold/Heat cannot injure without deficiency.' And: 'Deficient evil wind meets deficient body, then lodges.' Clearly, deficiency precedes wind strike. *Lingshu* adds: 'True Qi departs, Evil remains alone, causing hemiplegia.' Hard to treat, summarized in two phrases. *Tongping Xuushi Lun*: 'Treat Xiao-Dan, sudden falls, hemiplegia, flaccidity/Jue, Qi-fullness/reversal. Obese/noble people suffer from rich food/grease.' This implies Phlegm-Damp-Heat, Yin/Yang deficiency, not just wind strike. Obese/noble avoid wind; rich food generates internal wind. Liu, Li, Zhu families realized this. Treat root. Falls/Hemiplegia root in deficiency. Reading Liu Zongnong's *Yuji Wei Yi* and Wang Yutai's *Linglan Yaolan*, I confirm: Northern regions have True Stroke; Jiangnan has Similar Stroke. Miao Zhongchun argued True Yin deficiency causes heat, boiling fluids..."
