【纲】仲景曰。伤寒三日。阳明脉大。
【目】朱肱曰。足阳明胃之经。从鼻起。挟于鼻。络于目。下分为四道。并正别脉六道。上下
行腹。纲维于身。盖诸阳在表。阳阴主肌肉。络于鼻。故病患身热目疼。鼻干不得卧。其脉尺寸俱
长者。知阳明经受病也。
戴原礼曰。脉大者。两阳合明。内外皆阳之象也。阳明受病之初。病为在表。脉但浮而未大。
与太阳同。故亦有麻黄桂枝症也。至二日恶寒自止而反恶热。三日热大盛。故脉亦应其象而洪大。
此为胃家实之正脉。若小而不大。便属少阳。内经云。阳明之至短而涩。此指秋金司令之时脉言也。
又曰。阳明脉象大浮也。此指两阳合明之病脉言也。
喻昌曰。伤寒一日太阳。二日阳明。三日少阳。乃传经之次第。其实不以日拘。此三日阳明脉大。
正见二日之阳明传自太阳。必兼乎浮紧浮缓。未定是正阳阳明也。若正阳阳明。气血俱多。其脉
必大。而与太阳别矣。言外见三日。症连少阳。则其脉必大而弦。又不得为正阳阳明也。
魏荔彤曰。阳明之为病。胃家实。何以验之。验之于脉。如其人本太阳伤寒。三日之久。表邪
不解。致变热传里。入阳明。成胃家实。则其脉浮紧浮缓者。忽变为大。浮与紧缓。俱不见矣。既不
浮。则沉可知也。既云大。则沉而兼滑又可知也。向者太阳之浮。候于寸者既多。今者阳明之沉。候
于关者必多也。关脉大而沉滑。恰是中脘为病。则胃家之实。可决也。
【纲】仲景曰。脉浮而大。心下反硬。有热属脏者。攻之。不令发汗。属腑者。不令溲数。溲
数则大便硬。汗多则热愈。汗少则
便难。脉迟尚未可攻。（以上论胃实）
【目】柯琴曰。此治阳明之大法也。夫脉之浮而紧。浮而缓。浮而数。浮而迟者。皆不可攻而

者禁也。
朱肱曰。问。伤寒何以须诊冲阳脉。答曰。冲阳脉。是足阳明胃之经。人受气于谷。谷入于胃。
乃传与五脏六腑。脏腑皆受气于胃。其清者为营。浊者为卫。营行脉中。卫行脉外。阴阳相贯。
如环无端。胃为水谷之海。主禀四时。皆以胃气为本。是谓四时之变病。死生之要会。故伤寒必诊
冲阳。以察其胃之有无也。冲阳二穴。一名会源。在足跗上五寸骨间动脉上。去陷骨三寸。
【纲】仲景曰。阳脉微而汗出少者。为自和也。汗出多者。为太过。阳脉实。因汗出多者。亦

【目】朱肱曰。问。十二经皆一。而阳明有三。何也。有太阳阳明。有少阳阳明。有正阳阳明也。

三阳明俱宜下。惟恶寒及中寒为病在经。与太阳合病属表。可发其汗。盖太阳与阳明合病。脉必浮
大而长。症必头疼腰痛。肌热目痛鼻干也。脉浮大者。太阳也。长者。阳明也。头疼腰痛者。太阳
也。肌热目痛鼻干者。阳明也。尚恶寒者。可升麻汤汗之。若不恶寒反恶热。大便不秘者。可白虎
汤解利之。不恶寒反恶热。大便秘。或谵语者。属胃家实也。可调胃承气汤下之。身热汗出 然
者。属阳明也。
张介宾曰。太阳阳明者。邪自太阳传入于胃。其名脾约。以其小便数。大便硬也。正阳阳明者。
邪自阳明本经传入于腑。而邪实于胃也。少阳阳明者。邪自少阳传入于胃也。胃本属土。为万物
所归。邪入于胃。则无所复传。郁而为热。此由耗亡津液。胃中干燥。或三阳热邪不解。自经而腑。
热结所成。故邪入阳明胃腑者。谓之实邪。土气为邪。王于申未。
所以日晡潮热者。属阳明也。论曰。潮热者。实也。是为可下之症。然虽可下。若脉浮而紧。或小
便难大便溏。身热无汗。此热邪未全入腑。犹属表症。仍当和解。若邪热在表而妄攻之。则祸不旋

中虚冷。当不能食。今反能食。此名除中。必死。若脉迟。至六七日不欲食。此为晚发。水停中故
也。为未解。食自可者。为欲解。（以上论阳明中寒）
【目】陈士铎曰。伤寒脉迟。自然是寒。误与黄芩汤。则益加寒矣。寒盛宜不能食。今反能食。
病名除中。仲景谓是死症者何也。夫能食是胃气有余。如何反曰死症。不知胃寒而加之寒药。反
致能食者。此胃气欲绝。转见假食之象。不过一时能食。病名除中者。正言胃中之气。除去而不可

【目】柯琴曰。言太阳病。头项强痛可知。以脉辨之。关上者。阳明之脉。细弦数而不洪大。
虽自汗而不恶热。则不是与阳明并病。不口干烦满而自汗出。自不与少阴两感。原其故。乃庸医妄吐

【目】方中行曰。脉迟汗出等八症。乃阳明之外邪欲解。可以攻里而不为大误也。然曰欲解。
【目】朱肱说：足阳明胃经，从鼻旁起始，夹行于鼻部两侧，联络于眼部，向下分为四条通道，连同正脉和别脉共六道经脉，上下行走于腹部，维系全身。大概因为诸阳经在体表，而阳明主司肌肉，且络属于鼻，所以患者出现身体发热、眼睛疼痛、鼻干、无法安卧等症状，且寸口尺口的脉象都呈现长象，可知是阳明经受邪所致。
戴原礼说：脉象大，是因为两阳相合而显明，是内外皆属阳的征象。阳明受病的初期，病位在表，脉象仅见浮象而未变大，这与太阳病相同，因此也会出现麻黄汤证或桂枝汤证的症状。到了第二天，恶寒自然停止反而怕热；第三天热势盛大，所以脉象也随之变得洪大。这是“胃家实”的正脉。如果脉象小而不大，便属于少阳病。《内经》说：“阳明之至，脉短而涩”，这是指秋季金气当令时的正常脉象而言。又说：“阳明脉象大且浮”，这是指两阳相合发病时的病脉而言。
喻昌说：伤寒第一天传太阳，第二天传阳明，第三天传少阳，这是传经的顺序。但实际上并不拘泥于天数。这里说“三日阳明脉大”，正是说明第二天的阳明病是从太阳传变而来，必然兼有浮紧或浮缓的脉象，尚未确定为“正阳阳明”。如果是正阳阳明，气血俱盛，其脉必然盛大，从而与太阳病区别开来。言外之意，如果到了第三天，症状牵连少阳，那么脉象必然既大又弦，这就不能称为正阳阳明了。
魏荔彤说：阳明病的特征，在于“胃家实”。如何验证呢？通过脉象来验证。如果此人原本患太阳伤寒，经过三天之久，表邪未解，导致化热传入体内，进入阳明，形成胃家实，那么他原本浮紧或浮缓的脉象，会突然变为大脉，浮象与紧缓之象都不见了。既然不浮，那么沉象就可知了；既然说是大脉，那么沉而兼滑也就可知了。先前太阳病的浮脉，多在寸部显现较多；如今阳明病的沉脉，必在关部显现较多。关脉大而沉滑，恰好对应中脘部位有病，那么胃家实的诊断就可以确定了。
【纲】张仲景说：脉象浮而大，心下（胃脘部）反而坚硬，有热邪归属于脏的，应当用攻下法，不要发汗；热邪归属于腑的，不要利小便。利小便则大便变硬，发汗多则热更甚，发汗少则排便困难。脉迟者，尚不可攻下。（以上论述胃实证）
【目】柯琴说：这是治疗阳明病的大法。脉象浮紧、浮缓、浮数、浮迟的，都不可攻下而可发汗。唯独这脉浮而反不可发汗而可攻下的原因，是因为阳明病第三天的脉象，应当知道“大”代表病势进展，不可拘泥于“浮”就在表。又说“脉迟尚不可攻下”，是因为症状有虚实，脉象有真假。假如脉迟，就不是脏实，那么浮大都属于虚证了。这是特别禁止对实证妄加攻伐。
朱肱说：问：为什么伤寒必须诊察冲阳脉？答：冲阳脉是足阳明胃经的原穴。人受纳水谷之气，食物进入胃中，然后传输给五脏六腑。脏腑都依赖胃气，其中清轻的部分化为营气，浊重的部分化为卫气。营气行于脉中，卫气行于脉外，阴阳相互贯通，如环无端。胃是水谷之海，主宰顺应四时变化，都以胃气为根本，这被称为四时变化的关键，也是决定生死的重要环节。所以伤寒病必须诊察冲阳脉，以观察胃气的有无。冲阳穴有两个名称，一名会源，位于足背上方五寸处的骨间动脉上，距离陷谷穴三寸。
【纲】张仲景说：阳脉微细且汗出少的，是自和的表现；汗出多的，是太过。阳脉实盛，因汗出多的，也属于太过。太过会导致阳气实于里，津液亡失，大便因此变硬。
【目】危亦林说：这虽然是指太阳病转属的情况，但阳明表证也有这种情况。
【纲】张仲景说：太阳病，寸脉缓、关脉浮、尺脉弱，患者发汗后出汗，仍然恶寒且不呕吐，只是心下痞塞，这是因为医生误用下法所致。如果没有误下，患者不恶寒而口渴，这是转属阳明。小便频数的，大便必然变硬，即使十天不大便也没有痛苦。想喝水，少量给予即可，只需依法救治，适宜用五苓散。伤寒脉浮缓，手足自温的，病系在太阴。太阴病的人，身体应当发黄，如果小便通利的，就不会发黄。到了七八天，大便变硬的，就是阳明病了。（以上论述其他经转属阳明）
【目】柯琴说：上一条的病机，在于渴欲饮水，利水是治疗胃家实而脉弱的正确方法。不用猪苓汤而用五苓散，是因为表热未除的缘故。这是太阳阳明并病。下一条的病机，在于小便。太阴受病，转属阳明，因为阳明是燥土，所以不是经络表里直接相关所致，总归是因为亡失津液而导致的。
【纲】张仲景说：问：脉象有阳结和阴结，如何区别？答：脉象浮而数，能进食但大便不通的，这是实证，名叫阳结。预计十七天病情会加重。脉象沉而迟，不能进食，身体沉重，大便反而变硬的，名叫阴结。预计十四天病情会加重。（以上论述阴阳结症）
【目】张云岐说：这一条，本是论述阴结，阳结即是胃实，作为阴结的伴随情况罢了。阴结没有表证，应当归属于少阴，不可以身体沉重、不能进食作为阳明应有的症状，也不可以把沉迟作为阳明应当见到的脉象。大便硬是胃家实，但不敢用温补法。
【纲】张仲景说：阳明病，脉迟，汗出多，轻微恶寒的，表证未解，可以发汗，适宜用桂枝汤。阳明病，脉浮，无汗且喘息的，发汗则痊愈，适宜用麻黄汤。阳明病，脉浮而紧的，必定有潮热，发作有定时；只见浮脉的，必定有盗汗；脉浮而迟，面部发热发红且颤抖畏缩的，六七天应当汗出而解。迟脉表示无阳，不能作汗，身体会感到瘙痒。
【目】魏荔彤说：太阳中风或伤寒，解肌法未能完全解除肌表之邪，发汗法未能使汗完全排出，外邪气转化为热，内正阳生热，阴燥阳绝，太阳病已经转属阳明了。然而疾病有已入阳明但未离开太阳的，那么中风和伤寒两条，仍在表而未完全清除。怎么可以立即舍弃太阳的表治，而从阳明的里治呢？所以仲景特意列举前两条以确立法则。这大概是太阳阳明的症状，入阳明不深，所以让邪气仍从表而出，不至于归于胃而无所复传。这是解肌和发汗两种方法，始终条理分明。第三条，是阳明病仍带有太阳症状，深恐阳明病离太阳渐远而成阳明渐多，如果不结合脉症来阐明，是不审慎的。脉浮紧，由太阳伤寒而成，是寒伤营分而导致成为阳明的脉症；脉但浮，由太阳中风而成，是风伤卫分而导致成为阳明的脉症。阳明病到了这一步，即将离开太阳八九分了，而尚有一二分太阳在主治，还应当以下之过早为戒，以防结胸和痞证。第四条，是阳明病的虚脉虚症。汗是阳气，迟是阴脉，无阳不能作汗，又应当助阳发汗。
【纲】张仲景说：脉浮发热，口干鼻燥，能进食的，则会鼻衄（流鼻血）。（以上论述阳明在表症）
【目】楼全善说：这一条的主治，适宜用桃仁承气汤、犀角地黄汤之类的方剂。
【纲】张仲景说：伤寒四五日，脉沉且喘息胀满。沉脉表示病在里，却反而发其汗，津液越出体外，大便变得困难，表虚里实，时间久了会出现谵语。发汗过多，如果再重发汗，会亡失阳气。谵语且脉短的预后不良，脉象自和的不会死亡。（以上论述阳明谵语症）
【目】朱肱说：表虚里实，是谵语产生的原因。谵语且脉短，是谵语的脉象。汗多则津液脱失、营血虚弱，所以脉短。如果津液虽脱失但不严重，营血虽虚弱但不严重，那么脉象自和。
【纲】张仲景说：阳明中风，口苦咽干，腹部胀满轻微喘息，发热恶寒，脉浮而紧。如果误用下法，则腹部胀满，小便困难。
【目】沈金鳌按：脉浮而紧，是有潮热发作的时候，这是阳明初病在里的表证。
【纲】张仲景说：阳明中风，脉弦、浮、大且短气，腹部胀满，胁下及心口疼痛，久按之气不通畅，鼻干不得汗，嗜睡，全身及面目都发黄，小便难，有潮热，时时呃逆，耳前后肿胀。针刺后稍好转，但表证未解。病过十天，脉弦紧的，给予小柴胡汤。脉但浮，没有其他症状的，给予麻黄汤。如果不排尿，腹部胀满，加上呃逆的，属于不治之症。（以上论述阳明中风）
【目】朱肱说：问：十二经都是一样，而阳明有三种，为什么呢？有太阳阳明，有少阳阳明，有正阳阳明。太阳阳明，原本是太阳病，如果发汗，如果下法，如果利小便，这样亡失津液，胃中干燥，因而转属阳明。少阳阳明，原本是传到少阳，因发汗、利小便后，胃中燥实，大便困难。正阳阳明，患者原本风气盛、正气实。三种阳明都适宜用下法，只有恶寒及中寒为病在经，与太阳合病属于表证，可以发汗。大概太阳与阳明合病，脉必浮大而长，症状必有头痛腰痛、肌肤发热、眼睛疼痛、鼻干等。脉浮大，是太阳病；脉长，是阳明病；头痛腰痛，是太阳病；肌肤发热、眼睛疼痛、鼻干，是阳明病。还恶寒的，可用升麻汤发汗；如果不恶寒反而恶热，大便不秘结的，可用白虎汤解利；不恶寒反而恶热，大便秘结，或有谵语的，属于胃家实，可调胃承气汤攻下。身体发热、汗出濈然不断的，属于阳明病。
张介宾说：太阳阳明，是邪气从太阳传入胃，其名脾约，因为小便频数，大便硬。正阳阳明，是邪气从阳明本经传入腑，而邪气实于胃。少阳阳明，是邪气从少阳传入胃。胃本来属土，是万物所归之处，邪气进入胃，则无所复传，郁积而为热，这是由于耗亡津液，胃中干燥，或者三阳热邪不解，自经传入腑，热结所成。所以邪气进入阳明胃腑的，叫做实邪。土气在申、未时旺盛。
所以说日晡时潮热的，属于阳明。论中说：潮热，是实证，这是可以攻下的症状。然而虽然可以攻下，如果脉浮而紧，或小便难大便溏，身体发热无汗，这说明热邪未完全入腑，仍属于表证，仍应当和解。如果邪热在表而妄加攻下，则灾祸不远。
【纲】张仲景说：阳明病，脉迟腹满，进食难以吃饱，饱则轻微心烦，头晕目眩，必定小便难，这是将要发生谷疸。即使使用下法，腹满依旧。之所以这样，是因为脉迟的缘故。
【目】沈金鳌按：阳明中风，其脉应当浮而弦大，现在脉迟，是中寒，且无阳气了。
【纲】张仲景说：伤寒脉迟，六七天反而给予黄芩汤清除其热。脉迟为寒，现在给予黄芩汤再次清除其热，腹中虚冷，应当不能进食。现在反而能进食，这名叫“除中”，必死。如果脉迟，到六七天不想吃东西，这是晚发，因为有水饮停在中焦的缘故，病未解。如果能自己想吃东西，是病欲解。（以上论述阳明中寒）
【目】陈士铎说：伤寒脉迟，自然是寒证。误用黄芩汤，则更加寒凉。寒盛应当不能进食，现在反而能进食，病名叫除中。仲景说是死症为什么呢？能食是胃气有余，怎么反而说是死症？不知道胃寒而加之寒药，反而导致能食的，这是胃气欲绝，转而出现假性进食的现象。不过是一时能食，病名叫除中，正是说胃中之气，除去而不可留也。虽然是死症，犹有生机，终究因为其能食，胃气将除而未除，可用药物来留住其胃气。方剂用加减参苓汤。
王履说：凡是说阳明病的，必定身热汗出不恶寒反恶热。现在只说伤寒，则恶寒可知，并非不恶寒。何况脉迟为无阳，必定其里寒特别严重。
【纲】张仲景说：阳明病，脉浮而紧，咽燥口苦，腹部胀满而喘，发热汗出，不恶寒反恶热，身体沉重。如果发汗则烦躁，心中闷乱而谵语。如果加用烧针，心中恐惧惊惕，烦躁不得眠。如果误下，则胃中空虚，客气动膈，心中懊恼，舌上有苔的，栀子豉汤主治。如果脉浮发热，渴欲饮水，小便不利的，猪苓汤主治。
【目】吴绶说：仔细推敲脉浮而紧一条，是阳明半表里症。邪气已入腹，不在营卫之间。脉虽浮，不可认为在表而发汗；脉虽紧，不可因其身体沉重而加温针。胃家初实，尚未燥硬，不可因其喘满恶热而攻下。阳明栀子豉汤，犹如太阳桂枝汤，既可驱邪，也可纠正误治。
虞抟说：上一条，是不肯让胃燥；下一条，是不肯让水浸入胃。总归是为胃家爱惜津液。
【纲】张仲景说：病症像桂枝证，头不痛，项不强，寸脉微浮，胸中痞塞坚硬，气上冲咽喉不得呼吸的，这是胸中有寒饮，应当吐之，适宜瓜蒂散。
【目】沈金鳌按：寸脉微浮，尚是阳明之表脉，用瓜蒂散，即是阳明之表剂。
【纲】张仲景说：患者手足厥冷，脉象忽然变紧的，邪气结在胸中，心下胀满且烦，饥饿但不能进食的，病在胸中，应当吐之，适宜瓜蒂散。
【目】沈金鳌按：紧脉本来主寒，现在说忽然变紧，正与厥冷相应，不厥冷时未必紧，这是寒结胸中的脉症。
【纲】张仲景说：太阳病，应当恶寒发热，现在自汗出，不恶寒发热，关上脉细数，是因为医生误用吐法造成的过错。这属于小逆。一二天吐之的，腹中饥，口不能食；三四天吐之的，不喜欢喝粥，想吃冷食，早晨吃晚上吐，这是医生误用吐法所致。
【目】柯琴说：说太阳病，可知头项强痛。通过脉象辨别，关上脉是阳明脉，细弦数而不洪大，虽然自汗但不恶热，则不是与阳明并病；不口干烦满而自汗出，自不与少阴两感。推究其原因，乃庸医妄用吐法所致，则自汗为表虚，脉细数为里热。
【纲】张仲景说：伤寒脉浮，发热无汗，其表证未解的，不可给予白虎汤。渴欲饮水，无表证的，白虎加人参汤主治。服用桂枝汤后，大汗出，大烦渴不解，脉洪大的，白虎加人参汤主治。
【目】黄仲理说：这两条，必须合看才能明白。盖前条是症状，后条是脉象。脉浮发热无汗，本是麻黄汤证尚存，即是表未解，更兼渴欲饮水，又是热入于里，这叫有表里证，应当用五苓散。
【纲】张仲景说：三阳合病，脉浮大在关上，只想睡觉，闭眼则出汗。
【目】程郊倩说：脉浮大，是阳脉。关上为阳所治，这是重阳了。与少阴脉沉细而只想睡的，自然不同。
【纲】张仲景说：伤寒脉浮滑，这是表有热，里有邪，白虎汤主治。伤寒脉滑而四肢厥冷的，里有热，白虎汤主治。
【目】柯琴说：这一条论脉不及症，因为有白虎汤证而推及其脉象。切勿据脉而不审其症。脉浮而滑为阳，阳主热。《内经》说：脉缓而滑曰热中。是浮为在表，滑为在里。这虽然表里并言，而重在里热，所谓结热在里，表里俱热。脉微而厥为寒厥，脉滑而厥为热厥，阳极似阴的症状，全凭脉象来辨别。
【纲】张仲景说：伤寒十三日不解，过经出现谵语的，因为有热，应当用汤药攻下。如果小便便秘的，大便应当硬，反而下利，脉象调和的，知道医生用了丸药攻下，这不是正确的治法。如果是自行下利，脉应当微，现在反而调和，这是内实，调胃承气汤主治。
【目】张云岐说：脉调和而不微，是脉有胃气。内实，是胃实。胃实则肠虚，所以必以调胃承气汤调理其胃。
【纲】张仲景说：阳明病，脉迟微汗出，不恶寒，身体必定沉重，短气腹满而喘，有潮热的，这是表证欲解，可以攻里。手足濈然汗出的，这是大便已硬，大承气汤主治。如果汗多，微发热恶寒的，表未解，其热不潮，不可给予承气汤。如果腹部大满不通的，可给予小承气汤，微微调和胃气，不要令其大泄下。
[Outline] Zhang Zhongjing said: In the course of a cold damage disease, after three days, the pulse of the Yangming channel manifests as large (Da).
[Commentary] Zhu Gong said: The Foot-Yangming Stomach channel originates from beside the nose, runs along both sides of the nose, connects with the eyes, and divides downward into four pathways. Together with the main and divergent channels, there are six pathways in total, traveling up and down the abdomen to support the body. Generally, all Yang channels are on the exterior, while Yangming governs the muscles and connects to the nose. Therefore, patients present with fever, eye pain, dry nose, and inability to lie down comfortably. If the pulses at both the Cun (inch) and Chi (cubit) positions are long, it indicates that the Yangming channel is affected.
Dai Yuanli said: A large pulse indicates the convergence of two Yang energies, manifesting as Yang within and without. At the beginning of Yangming disease, the pathogen is still on the exterior; the pulse is merely floating but not yet large, similar to Taiyang disease. Thus, symptoms of Mahuang Tang or Guizhi Tang may also appear. By the second day, aversion to cold ceases and is replaced by aversion to heat. By the third day, heat becomes intense, so the pulse becomes surging and large accordingly. This is the characteristic pulse for "Stomach Fullness-Excess" (Wei Jia Shi). If the pulse is small rather than large, it belongs to Shaoyang. The *Neijing* states: "When Yangming prevails, the pulse is short and choppy." This refers to the normal pulse during the season when Metal rules (Autumn). It also states: "The Yangming pulse is large and floating," which refers to the pathological pulse when two Yangs combine.
Yu Chang said: Cold damage transmits from Taiyang on the first day, Yangming on the second, and Shaoyang on the third; this is the sequence of transmission. However, one should not be rigidly bound by days. The statement "on the third day, the Yangming pulse is large" implies that the Yangming condition on the second day transmitted from Taiyang and must still carry floating-tight or floating-slow characteristics, indicating it has not yet become "Zheng Yang Yangming" (True Yang Yangming). If it were Zheng Yang Yangming, with abundant Qi and Blood, the pulse would necessarily be large, distinguishing it from Taiyang. Implicitly, if by the third day symptoms involve Shaoyang, the pulse would be large and wiry, thus not constituting Zheng Yang Yangming.
Wei Litong said: The hallmark of Yangming disease is "Stomach Fullness-Excess" (Wei Jia Shi). How is this verified? Through the pulse. If a patient originally had Taiyang cold damage, and after three days the exterior pathogen remains unresolved, transforming into heat and transmitting inward to Yangming to form Stomach Fullness-Excess, the previously floating-tight or floating-slow pulse will suddenly become large. The floating and tight/slow qualities disappear. Since it is no longer floating, sinking is implied; since it is large, sinking combined with slippery is inferred. Previously, the Taiyang floating pulse was prominent at the Cun position; now, the Yangming sinking pulse will be prominent at the Guan position. A large, sinking, and slippery Guan pulse corresponds precisely to pathology at the Zhongwan point, confirming Stomach Fullness-Excess.
[Outline] Zhang Zhongjing said: When the pulse is floating and large, and the epigastrium feels hard contrary to expectation, if the heat belongs to the Zang organs, use purgation; do not induce sweating. If the heat belongs to the Fu organs, do not promote frequent urination. Frequent urination leads to hard stool; excessive sweating increases heat; insufficient sweating leads to difficult defecation. If the pulse is slow, purgation is not yet indicated. (Above discusses Stomach Excess patterns)
[Commentary] Ke Qin said: This outlines the general treatment principle for Yangming disease. Pulses that are floating-tight, floating-slow, floating-rapid, or floating-slow are generally not suitable for purgation but can be treated with diaphoresis. However, in the case of a floating pulse here, diaphoresis is contraindicated, and purgation is indicated. This is because in the third day of Yangming disease, a "large" pulse indicates disease progression; one cannot rigidly assume "floating" always means the exterior. Furthermore, "if the pulse is slow, purgation is not yet indicated" exists because symptoms have deficiency/excess distinctions and pulses have true/false variations. If the pulse is slow, it is not internal excess; thus, floating and large pulses here indicate deficiency. This clause specifically prohibits reckless purgation.
Zhu Gong said: Question: Why must Chongyang pulse be examined in cold damage? Answer: Chongyang is the Yuan-source point of the Foot-Yangming Stomach channel. Humans derive Qi from grain; grain enters the stomach and distributes to the Zang and Fu organs. All organs rely on Stomach Qi. The clear part becomes Ying (Nutritive) Qi, circulating inside the vessels; the turbid part becomes Wei (Defensive) Qi, circulating outside the vessels. Yin and Yang interconnect like an endless circle. The Stomach is the sea of water and grain, adapting to the four seasons, rooted in Stomach Qi. This is the key to seasonal variations and life/death. Therefore, examining Chongyang assesses the presence of Stomach Qi. There are two Chongyang points, also called Huiyuan, located 5 cun above the foot dorsum between the bones on the arterial pulse, 3 cun from Xangu.
[Outline] Zhang Zhongjing said: If the Yang pulse is faint and sweating is slight, it indicates self-recovery. If sweating is excessive, it indicates excess. If the Yang pulse is full/excessive and sweating is profuse, it also indicates excess. Excess leads to Yang stagnating in the interior, loss of Body Fluids, and consequently hard stool.
[Commentary] Wei Yilin said: Although this refers to transmission from Taiyang, such patterns occur in Yangming exterior conditions as well.
[Outline] Zhang Zhongjing said: In Taiyang disease, with a slow Cun pulse, floating Guan pulse, and weak Chi pulse, if the patient sweats after treatment, continues to have aversion to cold, does not vomit, but experiences epigastric stuffiness, this is due to erroneous purgation by the physician. If purgation was not performed, and the patient is not averse to cold but is thirsty, this indicates transmission to Yangming. Frequent urination leads to hard stool; even if no bowel movement occurs for ten days without discomfort, it is acceptable. If thirsty for water, give small amounts frequently, treating according to principles, using Wuling San. In cold damage with a floating-slow pulse and warm hands/feet, the disease is associated with Taiyin. Taiyin patients typically develop jaundice; however, if urination is free, jaundice will not develop. By the seventh or eighth day, if stool becomes hard, it becomes a Yangming disease. (Above discusses transmission from other channels to Yangming)
[Commentary] Ke Qin said: The mechanism of the previous clause lies in thirst for water; promoting urination is the correct treatment for Stomach Fullness-Excess with a weak pulse. Wuling San is used instead of Zhuling Tang because the exterior heat is not yet resolved. This is a concurrent disease of Taiyang and Yangming. The mechanism of the next clause lies in urination. Transmission from Taiyin to Yangming occurs because Yangming is Dry Earth; it is not merely due to meridian interior-exterior relationships but primarily due to the loss of Body Fluids.
[Outline] Zhang Zhongjing said: Question: How to distinguish between Yang Constriction (Yang Jie) and Yin Constriction (Yin Jie) pulses? Answer: A floating and rapid pulse with ability to eat but inability to pass stool indicates Excess, named Yang Constriction. Expect worsening on the seventeenth day. A sinking and slow pulse with inability to eat, heavy body, and conversely hard stool indicates Yin Constriction. Expect worsening on the fourteenth day. (Above discusses Yin-Yang Constriction patterns)
[Commentary] Zhang Yunqi said: This clause primarily discusses Yin Constriction. Yang Constriction is essentially Stomach Excess, accompanying Yin Constriction. Yin Constriction lacks exterior symptoms and belongs to Shaoyin; one should not interpret heavy body and inability to eat as typical Yangming symptoms, nor sinking-slow pulse as typical Yangming pulse. Hard stool indicates Stomach Excess, precluding the use of warming tonification.
[Outline] Zhang Zhongjing said: In Yangming disease, with a slow pulse, profuse sweating, and slight aversion to cold, the exterior is unresolved; diaphoresis is permissible, using Guizhi Tang. In Yangming disease, with a floating pulse, no sweating, and wheezing, diaphoresis leads to recovery; use Mahuang Tang. In Yangming disease, with a floating-tight pulse, tidal fever will definitely occur at specific times; if only floating, night sweats will occur. With a floating-slow pulse, facial flushing, and trembling/fear, resolution via sweating should occur around the sixth or seventh day. Slow pulse indicates lack of Yang, inability to sweat, leading to itching.
[Commentary] Wei Litong said: In Taiyang wind-strike or cold damage, if muscle-relieving methods fail to fully resolve the exterior, or sweating fails to fully expel pathogens, external evil transforms into heat, and internal Zheng Yang generates heat. With Yin dryness and Yang exhaustion, Taiyang disease has transmitted to Yangming. However, some cases have entered Yangming but not left Taiyang entirely. Thus, the wind-strike and cold damage clauses remain relevant for residual exterior pathogens. One cannot abruptly abandon Taiyang exterior treatment for Yangming interior treatment. Zhongjing highlights these first two clauses to establish legal principles. These are Taiyang-Yangming concurrent symptoms where entry into Yangming is shallow, allowing pathogens to exit via the exterior, preventing them from settling in the Stomach and transmitting further. Muscle-relieving and sweating methods are applied systematically. The third clause involves Yangming disease retaining Taiyang features; fearing Yangming moves away from Taiyang and dominates, one must examine pulses and symptoms carefully. Floating-tight arises from Taiyang cold damage injuring Ying, becoming Yangming pulse/symptoms; floating alone arises from Taiyang wind-strike injuring Wei, becoming Yangming pulse/symptoms. By this stage, Yangming is nearly separated from Taiyang, yet some Taiyang remains. Caution against premature purgation to prevent chest binding and epigastric痞 (Pi). The fourth clause describes Yangming deficiency pulse and symptoms. Sweat is Yang Qi; slow is Yin pulse. Lack of Yang prevents sweating, requiring assistance of Yang to induce sweat.
[Outline] Zhang Zhongjing said: With floating pulse, fever, dry mouth, and dry nose, if the patient can eat, nasal hemorrhage (Xu) will occur. (Above discusses Yangming exterior patterns)
[Commentary] Lou Quanshan said: Treatment for this clause should utilize formulas like Taoren Chengqi Tang or Xijiao Dihuang Tang.
[Outline] Zhang Zhongjing said: In cold damage, on the fourth or fifth day, with sinking pulse and wheezing/fullness. Sinking indicates interior location. Erroneous sweating causes fluids to escape, making stool difficult. Exterior deficiency and interior excess lead to delirium over time. Excessive sweating, or repeated sweating, causes loss of Yang. Delirium with a short pulse indicates death; delirium with a harmonious pulse indicates survival. (Above discusses Yangming delirium patterns)
[Commentary] Zhu Gong said: Exterior deficiency and interior excess cause delirium. Delirium with short pulse is the corresponding pulse. Profuse sweating leads to fluid depletion and Ying deficiency, hence the short pulse. If fluid depletion and Ying deficiency are mild, the pulse remains harmonious.
[Outline] Zhang Zhongjing said: In Yangming wind-strike, with bitter taste, dry throat, abdominal fullness, slight wheezing, fever, aversion to cold, and floating-tight pulse. Erroneous purgation leads to abdominal fullness and difficulty urinating.
[Commentary] Shen Jin'ao notes: Floating-tight pulse with periodic tidal fever indicates early Yangming disease involving the interior's exterior aspect.
[Outline] Zhang Zhongjing said: In Yangming wind-strike, with wiry-floating-large pulse and shortness of breath, abdominal fullness, pain in the hypochondrium and heart region, obstruction of Qi upon prolonged pressing, dry nose, inability to sweat, lethargy, generalized and facial jaundice, difficulty urinating, tidal fever, frequent hiccups, and swelling before/behind the ears. Acupuncture provides slight relief, but exterior symptoms persist. After ten days, if the pulse is wiry-tight, administer Xiaochaihu Tang. If the pulse is merely floating with no other symptoms, administer Mahuang Tang. If urine stops, abdominal fullness worsens, and hiccups increase, it is untreatable. (Above discusses Yangming wind-strike)
[Commentary] Zhu Gong said: Question: Why are there three types of Yangming? Answer: Taiyang-Yangming, Shaoyang-Yangming, and Zheng Yang Yangming. Taiyang-Yangming results from Taiyang disease treated with sweating, purgation, or diuresis, causing fluid loss, dry stomach, and transmission to Yangming. Shaoyang-Yangming results from Shaoyang disease treated with sweating/diuresis, causing dry/stagnant stomach and difficult stool. Zheng Yang Yangming results from patients with inherent strong Wind and robust Qi. All three benefit from purgation, except when aversion to cold or interior cold indicates pathogen in the channel (exterior), treatable with sweating. Concurrent Taiyang-Yangming presents with floating-large-long pulse, headache, lower back pain, muscle heat, eye pain, dry nose. Floating-large is Taiyang; Long is Yangming; headache/back pain is Taiyang; muscle heat/eye pain/dry nose is Yangming. If aversion to cold persists, use Shengma Tang. If no aversion to cold but aversion to heat, with non-obstipated stool, use Baihu Tang. If no aversion to cold, aversion to heat, constipation, or delirium, it is Stomach Excess; use Tiaowei Chengqi Tang. Generalized heat with continuous sweating indicates Yangming.
Zhang Jiabin said: Taiyang-Yangming is pathogen transferring from Taiyang to Stomach, named Pi Yue (Spleen Restriction), characterized by frequent urination and hard stool. Zheng Yang Yangming is pathogen transferring from Yangming channel to Fu organ, creating Stomach Excess. Shaoyang-Yangming is pathogen transferring from Shaoyang to Stomach. Stomach belongs to Earth, the destination of all pathogens. Once entering Stomach, transmission stops, stagnating into heat due to fluid loss or unresolved Three-Yang heat. Pathogens entering Yangming Stomach Fu are called Excess Pathogens. Earth energy peaks at Shen/Wei hours (3-7 PM). Hence, afternoon tidal fever belongs to Yangming. Tidal fever indicates Excess, warranting purgation. However, if floating-tight pulse, difficult urination/loose stool, or heat/no sweat exist, pathogen is not fully in Fu; treat with harmonizing. Premature purgation of exterior heat brings disaster.
[Outline] Zhang Zhongjing said: In Yangming disease, with slow pulse and abdominal fullness, inability to eat much, slight vexation after eating, dizziness, and difficulty urinating, this suggests impending Grain Jaundice. Purging will not relieve abdominal fullness because of the slow pulse.
[Commentary] Shen Jin'ao notes: Yangming wind-strike pulse should be floating-wiry-large; a slow pulse indicates Interior Cold and lack of Yang.
[Outline] Zhang Zhongjing said: In cold damage with slow pulse, if Huangqin Tang is erroneously given on days 6-7 to clear heat, the slow pulse indicates Cold. Giving cooling herbs further damages the interior, causing cold deficiency and inability to eat. If the patient suddenly eats, it is named Chu Zhong (Elimination of the Middle), indicating death. If slow pulse persists to day 6-7 with anorexia, it is late onset due to water retention in the middle; the disease is unresolved. Spontaneous desire to eat indicates recovery. (Above discusses Yangming Interior Cold)
[Commentary] Chen Shiduo said: Slow pulse in cold damage indicates Cold. Erroneous Huangqin Tang exacerbates Cold. Severe Cold should cause anorexia; sudden appetite is Chu Zhong. Zhongjing calls it fatal because apparent appetite is a false sign of failing Stomach Qi trying to survive briefly. Though fatal, there is hope if Stomach Qi is not completely gone; use modified Shenling Tang to preserve Stomach Qi.
Wang Lü said: Yangming disease typically presents with heat, sweating, no aversion to cold, but aversion to heat. Mentioning only "cold damage" implies aversion to cold exists. Slow pulse indicates lack of Yang and severe Interior Cold.
[Outline] Zhang Zhongjing said: In Yangming disease, with floating-tight pulse, dry throat, bitter taste, abdominal fullness, wheezing, fever, sweating, no aversion to cold but aversion to heat, and heavy body. Erroneous sweating causes restlessness, mental confusion, and delirium. Moxibustion causes fear, irritability, and insomnia. Erroneous purgation leaves Stomach empty, allowing hostile Qi to disturb the Diaphragm, causing stifled sensation in the chest. With tongue coating, Zhizi Chi Tang is indicated. If floating pulse, fever, thirst, and difficulty urinating occur, Zhuling Tang is indicated.
[Commentary] Wu Shou said: The floating-tight clause represents a half-exterior/half-interior Yangming pattern. Pathogen is in the abdomen, not Ying/Wei. Floating pulse does not mean exterior; do not sweat. Tight pulse does not justify moxibustion despite heaviness. Initial Stomach Excess is not yet dry/hard; do not purge despite wheezing/heat. Zhizi Chi Tang acts like Guizhi Tang in Taiyang, dispelling pathogen and correcting errors.
Yu Tuan said: The first clause prevents Stomach dryness; the second prevents Water invading Stomach. Both aim to protect Stomach fluids.
[Outline] Zhang Zhongjing said: Symptoms resemble Guizhi Tang pattern, but without headache or stiff neck. Cun pulse is slightly floating, epigastrium is stuffy/hard, Qi rushes to throat obstructing breathing. This is Phlegm-Fluid in the Chest; induce vomiting with Goudi San.
[Commentary] Shen Jin'ao notes: Slightly floating Cun pulse is still a Yangming exterior pulse; Goudi San is a Yangming exterior formula.
[Outline] Zhang Zhongjing said: Patients with cold hands/feet and suddenly tight pulse have pathogen constrained in the Chest. Epigastric fullness/vexation, hunger but inability to eat indicates pathology in the Chest; induce vomiting with Goudi San.
[Commentary] Shen Jin'ao notes: Tight pulse indicates Cold. "Suddenly tight" correlates with cold limbs. When limbs are warm, pulse is not tight. This is Cold constraining the Chest.
[Outline] Zhang Zhongjing said: Taiyang disease should have aversion to cold and fever. Now, spontaneous sweating, no aversion to cold/fever, and thin-rapid Guan pulse result from erroneous vomiting by the physician. This is a minor error. Vomiting on days 1-2 causes hunger but inability to eat. Vomiting on days 3-4 causes dislike of congee, craving cold food, and morning-eating/evening-vomiting, caused by erroneous vomiting.
[Commentary] Ke Qin said: Taiyang disease implies headache/stiff neck. Guan pulse is Yangming; thin-wiry-rapid without large quality, plus sweating without heat aversion, excludes concurrent Yangming. No dry mouth/vexation excludes Shaoyin involvement. Cause is physician's erroneous vomiting. Sweating indicates exterior deficiency; thin-rapid pulse indicates interior heat.
[Outline] Zhang Zhongjing said: In cold damage with floating pulse, fever, and no sweating, if exterior is unresolved, Baihu Tang is contraindicated. If thirsty for water with no exterior signs, Baihu Jia Renshen Tang is indicated. After taking Guizhi Tang, if profuse sweating leads to severe vexation/thirst unrelieved by large pulse, Baihu Jia Renshen Tang is indicated.
[Commentary] Huang Zhongli said: These two clauses must be read together. The first addresses symptoms; the second addresses pulse. Floating fever/no sweating indicates Mahuang Tang pattern persists (exterior unresolved). Thirst indicates heat entering interior. This is exterior-interior complex; Wuling San is appropriate.
[Outline] Zhang Zhongjing said: In Three-Yang concurrent disease, pulse is floating-large at Guan. Patient desires sleep; sweating occurs when closing eyes.
[Commentary] Cheng Jiaoqian said: Floating-large is Yang pulse. Guan is governed by Yang, representing Double Yang. This differs from Shaoyin's sinking-thin pulse and desire to sleep.
[Outline] Zhang Zhongjing said: In cold damage, floating-slippery pulse indicates exterior heat and interior pathogen; Baihu Tang is indicated. In cold damage, slippery pulse with cold limbs indicates interior heat; Baihu Tang is indicated.
[Commentary] Ke Qin said: This clause discusses pulse based on Baihu Tang syndrome. Do not judge solely by pulse. Floating-slippery is Yang, governing Heat. *Neijing* says: "Slow-slippy pulse indicates Heat in Middle." Floating is exterior, Slippery is interior. Emphasis is on Interior Heat, i.e., Heat knotting in interior with exterior-interior heat. Micro-cold limbs is Cold Jue; Slippery-cold limbs is Heat Jue (Extreme Yang resembling Yin). Pulse differentiation is crucial.
[Outline] Zhang Zhongjing said: After thirteen days of unresolved cold damage, if delirium occurs post-transmission, it is due to Heat; treat with decoction purgation. If urine is scant, stool should be hard; if diarrhea occurs instead, and pulse is harmonious, it indicates physician used pill purgatives incorrectly. If spontaneous diarrhea, pulse should be micro; if harmonious, it indicates Internal Excess. Tiaowei Chengqi Tang is indicated.
[Commentary] Zhang Yunqi said: Harmonious pulse without micro quality indicates Stomach Qi. Internal Excess is Stomach Excess. When Stomach is excess, Intestines are deficient; thus, Tiaowei Chengqi Tang regulates the Stomach.
[Outline] Zhang Zhongjing said: In Yangming disease, with slow pulse, slight sweating, no aversion to cold, heavy body, shortness of breath, abdominal fullness, wheezing, and tidal fever, the exterior is resolving, and interior purgation is permissible. Continuous sweating on hands/feet indicates hard stool; Dachengqi Tang is indicated. If profuse sweating, slight fever/aversion to cold, exterior is unresolved; if no tidal fever, do not use Chengqi Tang. If severe abdominal fullness/obstruction, Xiao Chengqi Tang may be used to mildly harmonize Stomach Qi, avoiding drastic purgation.
[Commentary] Fang Zhongxing said: The eight symptoms (slow pulse, sweating, etc.) indicate exterior pathogen resolving, allowing interior purgation without major error. However, "resolving" implies...
