问曰。病有太阳阳明。有正阳阳明。有少阳阳明。何谓也。答曰太阳阳明者。脾约是也。正阳阳明者。胃家实是也。
少阳阳明者。发汗利小便已。胃中燥烦实大便难是也。
脾约者。其人津液素槁。邪热在太阳时。大便即难是也。太阳阳明者。太阳经邪热不俟。入阳明经而便入胃腑也。
正阳阳明者。经邪传腑表邪并里故云胃家实也。少阳阳明者。发汗利小便已。胃中燥烦实大便难津液耗竭也。尚论以阳
明经传少阳经即为少阳阳明非也。若经邪传经则胃中未必便燥而大便难。如果阳明经传少阳证。即当言阳明少阳不得谓
之少阳阳明矣。
阳明之为病胃家实也。
问曰何缘得阳明病。答曰。太阳病发汗。若下若利小便。此亡津液胃中干燥。因转属阳明不更衣内实大便难者。此
名阳明也。
问曰阳明病外证云何。答曰。身热汗自出。不恶寒。反恶热也。
问曰病有得之一日。不恶寒而发热者。何也答曰。虽得之一日恶寒。将自罢即自汗出。而恶热也。
问曰。恶寒何故自罢。答曰。阳明居中土也。万物所归无所复传。始虽恶寒二日自止。此为阳明病也。
本太阳初得病时发其汗。汗先出不彻。因转属阳明也。
伤寒发热无汗。呕不能食。而反汗出。 然者。是转属阳明也。
伤寒转系阳明者。其人 然微汗出也。
既 然汗出。则热除呕止可知。
脉阳微而汗出少者为自和也。汗出多者为太过。阳脉实因发其汗出多者。亦为太过。太过为阳绝于里亡津液大便因
硬也。
中风之脉轻微而缓者。为风邪本微。汗出少而不为过也。伤寒之脉。已至于实。即将去太阳而成可下之证也。况过
发其汗。宁无亡津液。大便因鞭。致传阳明之证乎。
以上统论阳明腑证传受。
阳明中风。口苦咽干腹满微喘。发热恶寒。脉浮而紧。若下之。则腹满小便难也。
此虽曰阳明中风。而证俱见伤寒太阳。未除之候但以腹满一端。知认为热入阳明。然终与大实大满不同。若误下则
邪愈陷。而腹愈满矣。小便难者。亡津液也。
阳明病脉迟。食难用饱。饱则微烦头眩。必小便难。此欲作谷瘅。虽下之腹满如故。所以然者。脉迟故也。
脉迟则表证将除。然得食而微烦。仍是外邪助其内热也。头眩者。风邪上攻也。小便难者。湿郁水道也。水谷之湿。

溏泄久而不止。则曰固瘕。言如 瘕固结不散也。
阳明病欲食。小便反不利。大便自调其人骨节疼。翕翕如有热状。奄然发狂。 然汗出而解也。此本不胜谷气。与

腠开。 然大汗而解。则脉之紧亦自和也。
阳明病不能食。攻其热必哕所以然者。胃中虚冷故也以其人本虚故攻其热必哕。（哕于月切）

此五条一云食难用饱。一云欲食似乎指中风而言。一云中寒不能食。及后二条又明指中寒而言。所以后人拘执其说
而误为注释也。不知此五条辨胃气之强弱。非辨外邪也。故五证中。惟水不胜谷气。脉紧则愈一证为胃气胜。其四条。

脏也且戒之曰不令发汗。急当攻之此所谓证书不凭脉也。
属腑者。不入溲数。溲数则大便硬。汗多则热愈。汗少则便难。脉迟尚未可攻。
邪入阳明之腑。必自汗小便多。以其实热内结。津液滂渗。也是以仲景有阳明病汗多。禁利小便之戒。此热邪虽入
阳明而未作里实犹宜和解。如小柴胡热服亦能出汗。汗多则邪从汗解而热愈汗少则邪热内结。而便难若脉迟为热尚少。
结水定硬须俟脉数结定然后攻之。○二条旧在脉法篇中今归此。
太阳病二日而发汗不解。蒸蒸发热者。属胃也调胃承气汤主之。
本太阳中风。误用麻黄发汗。汗出过多。反伤胃中津液。所以不解。热邪乘虚内入。而为表里之证也。蒸蒸者热则
有内胜达于外也。惟热在胃故用承气以调其胃。胃调则病涣然除矣。
伤寒吐后腹胀满者。与调胃承气汤。
吐后腹满。则邪不在胸其为里实可知。但腹满而不痛。终属表邪入里未实。故不宜峻下。少与调胃承气和之可也。
阳明病不吐不下。心烦者。可与调胃承气汤。
胃气及津液。既不由吐下而伤则心烦明系胃中热炽。故可与调胃承气以安胃而全津液也。可与者。欲人临病裁酌不

太阳病过经十余日。心下温温欲吐而不吐。其人胸中痛。大便反溏腹微满郁郁微烦者。此有二辨若曾经大吐大下。
问：病有太阳阳明、正阳阳明、少阳阳明，这是什么意思？
答：太阳阳明，是指脾约证。正阳阳明，是指胃家实证。
少阳阳明，是指经过发汗或利小便治疗后，导致胃中干燥、烦闷、实热，大便困难的情况。
所谓脾约，是因为患者素来津液枯竭，当邪热在太阳经时，大便就已经困难了。所谓太阳阳明，是太阳经的邪热不等待（自行消退），直接进入阳明经并传入胃腑。
所谓正阳阳明，是经络之邪传入腑脏，表邪并入里，所以称为胃家实。
所谓少阳阳明，是经过发汗和利小便后，津液耗竭，导致胃中干燥、烦闷、实热、大便困难。尚论派认为阳明经邪传至少阳经即为少阳阳明，这是错误的。如果经邪传经，胃中未必就会干燥且大便困难。如果是阳明经邪传给少阳证，就应该称为“阳明少阳”，而不能称之为“少阳阳明”。
阳明病的提纲是：胃家实。
问：为什么会得阳明病？
答：太阳病经过发汗、攻下或利小便治疗，导致津液亡失，胃中干燥，从而转属为阳明病。如果不解大便，体内实热，大便困难，这就叫作阳明病。
问：阳明病的外在证候是什么？
答：身体发热，自然出汗，不怕冷，反而怕热。
问：有的病刚得一天，就不怕冷而发热，这是什么原因？
答：虽然刚得病一天，起初可能有恶寒，但很快就会自行停止，随即出现自汗出，并且怕热。
问：恶寒为什么会自动停止？
答：因为阳明居中焦属土，万物所归，病邪不再传变。开始虽然有恶寒，但到第二天就会自动停止，这就是阳明病。
本来的太阳病，初得病时发汗，但汗出不透彻，因此转属为阳明病。
伤寒发热无汗，呕吐不能进食，反而汗出濈然（连续不断）的，这是转属阳明病。
伤寒转系于阳明的，患者会濈然微汗出。
既然已经濈然汗出，那么热邪除尽、呕吐停止是可以推知的。
脉象寸部微弱而汗出少的，是正气自和的表现；汗出多的，就是太过。如果阳脉实大，因发汗过多，也是太过。太过会导致阳气绝于内，津液亡失，大便因此坚硬。
中风病的脉象轻微而缓的，说明风邪本来轻微，汗出少而不算过度。伤寒病的脉象，已经到了实大的程度，即将脱离太阳经而成为可以攻下的证候。何况过度发汗，难道不会导致津液亡失，大便因而坚硬，进而传入阳明病吗？
以上统论阳明腑证的传变。
阳明中风，口苦咽干，腹部胀满，微微气喘，发热恶寒，脉浮紧。如果误用攻下法，就会导致腹部胀满加重，小便困难。
这虽然叫作阳明中风，但证候都表现出伤寒太阳经未除的迹象，只是根据腹部胀满这一端，知道认为是热邪入阳明。然而终究与大实大满不同。如果误用攻下，邪气会更加深陷，腹部更加胀满。小便困难，是因为津液亡失。
阳明病，脉迟，吃东西不能吃饱，吃饱了就轻微心烦、头晕，一定小便困难，这是将要发生谷瘅（因饮食不当引起的黄疸）。即使使用攻下法，腹部胀满依然如故。之所以这样，是因为脉迟的缘故。
脉迟说明表证将除，但进食后轻微心烦，仍然是外邪助长内热。头晕，是风邪上攻。小便困难，是湿邪郁阻水道。水谷的湿气，得到热邪蒸腾而遍身发黄。攻下后腹部胀满如故，是因为腹满已经是邪气陷入，脉迟则胃气不实，徒然攻下其糟粕，病不仅不除，反而伤害身体。阳明证本当攻下，阳明病至腹痛，尤其应当急下。唯独这一个证候，攻下后腹腔胀满必然如故，原因是脉迟则胃气空虚，津液不充，其胀满不过是虚热内壅，不是结热当下之比。可见脉迟胃虚，攻下无益，发汗利小便的方法用之也无益，只应当用和法，如甘草干姜汤先温补其中，然后少量给予调胃承气汤，微微调和胃气。
阳明病，如果中寒不能进食，小便不利，手足濈然汗出，这是将要发生固瘕（一种慢性腹泻或积聚病），一定大便初硬后溏。之所以这样，是因为胃中寒冷，水谷不分的原因。
溏泄久而不止，就叫作固瘕。意思是像瘕块一样固结不散。
阳明病，想进食，小便反而不利，大便正常，患者骨节疼痛，微微像有发热的样子，突然发狂，濈然汗出而痊愈。这是因为原本不胜谷气，与汗共同排出。脉紧则会痊愈。
患者骨节疼痛，是湿胜。微微像有发热，是热胜。湿热相交，于是忽然发狂，濈然汗出而解。因为患者能进食，胃气有权力，能驱除阳明的水与热，所以水热不能胜过它，与汗一起排出。脉紧则愈，是因为先前失汗，所以脉紧未去，现在幸亏胃气强盛，所以肌腠开泄，濈然大汗而解，脉的紧象也自然平和。
阳明病不能进食，攻其热必呃逆。之所以这样，是因为胃中虚冷的缘故。因为患者本身体虚，所以攻其热必呃逆。（哕，音yuě，指呃逆）
脉浮而迟，表热里寒，下利清谷（泻下未消化的食物）的，主方用四逆汤。如果胃中虚冷不能进食，喝水就会呃逆。
表热里寒，治法应当先救其里。太阳经中已用四逆汤，其在阳明更可知矣。此条比前条虚寒更甚，所以不但攻其热必呃逆，就连喝水也呃逆。
这五条，一条说食难用饱，一条说欲食，似乎指中风而言；一条说中寒不能食，及后两条又明确指中寒而言。所以后人拘执其说而误为注释。不知道这五条是辨别胃气的强弱，而非辨别外邪。所以在五证中，只有“水不胜谷气，脉紧则愈”一证为胃气胜，其余四条，都是脉迟胃冷，反为水热所胜的证候。伤寒都是热证，但如果其人胃中虚冷，又不可一概而论。盖胃既虚冷，则水谷混然无别，热邪传入，必定不能立刻变为实证。胃不实，则不可攻下，即使用了攻下法，水热不去，只会令胃气垂绝而呃逆。仲景一一列举，而对于下利清谷一证，主以四逆汤，其较轻者，宜主以温胃，更不必说了。胃气素虚之人，外邪入之，必定转增其热。胃热故膀胱亦热，气化不行，小便因此不行，则尽注太阳，而为洞泄下利清谷。小便不利，乘胃热而渗于脾，则四肢先见色黄，乃至遍身发黄，而成谷瘅。手足濈然得汗，则脾中之湿热行，而色黄谷瘅可免。但汗从手足而出，水谷之气，未得遍泄于周身，不过少分大肠奔迫之势，故不为洞泄而为瘕泄耳。无病之人，小便不行尚且会引发他病，何况伤寒极赤极热的小便，停蓄不行，能不产生这三种变化吗？
伤寒大吐大下之后，极度虚弱，又极度汗出的，是因为患者外气怫郁，又给他喝水以发其汗，因此导致呃逆。之所以这样，是因为胃中寒冷的缘故。
伤寒呃逆且腹部胀满，观察前后二阴，知道哪一部不利，通利之则痊愈。
一是胃气虚寒，一是胃中实热，不可不辨别。虚寒者温之，用四逆汤、理中汤等。实热者利之，用承气汤、五苓散等。
○这两条旧时在厥阴篇末，今收入此处。
得病六七日，脉迟浮弱，恶风寒，手足温。医生二三度攻下，导致不能进食，胁下满痛，面目及全身发黄，颈项强，小便难。给予柴胡汤后，必定出现下重感。本来口渴而饮水呕吐的，柴胡汤不与服用。进食则呃逆。
六七天没有大热，手足温，邪气将入于里。因为脉迟浮弱，所以尚留连肌表，恶风未除。反而二三度攻下，致使太阳之邪内陷，胃气虚寒，不能进食，胁下满痛似痞非痞，面目及全身发黄，颈项强，小便难，这是上下寒饮停结。只宜五苓散解利。如果认作少阳，又给予柴胡寒剂，必定出现下重、呕逆，这都是亡津液、胃寒的征象。
病患脉数，数为热，应当消谷引食，反而呕吐的，这是因为发汗令阳气微弱，膈内虚，脉乃数。数为客热，不能消谷，因为胃中虚冷，所以呕吐。
凡脉见阳盛则数，阴盛则迟。其人阳气既微，为何脉反数？脉既数可得胃反冷，此不可不求其故。盖脉之数由于误用辛温发散而遗留客热，胃之冷由于阳气不足而生其内寒。医生见其脉数，反以寒剂泻其无过，必致上下之阳俱损，其后脉从阴而变为弦，胃气无余，变为反胃。
阳明病发热汗出，这叫热越（热邪向外发散），不能发黄。只是头汗出，身上无汗，齐颈而还，小便不利，渴引水浆的，这叫瘀热在里，身体必定发黄，茵陈蒿汤主之。
瘀热在里而用茵陈蒿汤，与太阳寒湿身黄如橘者同意，然而彼因腹微满，此因渴饮水浆，所以用大黄佐茵陈，驱热利湿。
阳明病面色合赤色，不可攻之。攻之必发热色黄，小便不利。
下虚之人，才感外邪则挟虚火而面色通红。在太阳时，即不可妄用发汗，何况在阳明可妄下乎？总由真阳素虚，无根之火随表药之性上升，即咽干烦躁足冷随里药之性下降，则发热色黄，小便不利。
阳明病无汗，小便不利，心中懊憹（烦闷不安）的，身体必定发黄。
外不得汗，下不得溺，而热郁胸中不得泄热，必蒸身为黄。
阳明病被火疗，额上微汗出，小便不利的，必定发黄。
合这四条来看，阳明病湿停热郁而烦渴有加，势必发黄。然而汗出热从外越，则黄可免；小便多热从下泄，则黄可免。若误下之，则热邪愈陷，津液愈伤，而汗与小便，愈不可得。误火之，则热邪愈炽，津液上奔，额虽微汗，而周身之汗与小便愈不得。发黄之变，怎么能避免呢？发黄与前谷瘅本同一证，但彼因脉迟胃冷而得，则与固瘕及呃逆同源异派。
阳明病下血谵语的，这叫热入血室。只是头汗出的，刺期门穴，随其实而泻之，濈然汗出则愈。
妇人经水，适来适断，则邪热乘之而入于血室。男子阳明经下血而谵语者，亦为热入血室。总是邪热乘虚而入。曾见大吐血后停食，感寒发热至夜谵语的，也以热入血室治之而愈。明理论曰：冲脉是血室，妇人则随经而入，男子由阳明而入。
阳明病，其人善忘（健忘）的，必有蓄血。之所以这样，是因为本有久瘀血，故令善忘。屎虽硬，大便反易，其色必黑，宜抵当汤主之。
太阳热结膀胱，轻者如狂，用桃核承气汤；重则发狂，用抵当汤。此阳明善忘之证，本差减于如狂，乃用抵当汤峻攻之者，因为阳明多血，阳明之血结，则较太阳为难动。○按大便色黑虽曰瘀血，而热邪燥结之色，未尝不黑。但瘀血则粘黑如漆，燥结则晦黑如煤，此为明辨。
病患无表里证，发热七八日，虽脉浮数者可下之。假令已下，脉数不解，合热则消谷善饥，至六七日，不大便者，有瘀血，宜抵当汤。若脉数不解，而下不止，必协热便脓血。
病虽七八日尚发热，脉浮数，仍属太阳表证，因误下引邪入内，所以脉数不解。内外合邪，而见消谷善食。谷入既多，反至六七日，不大便且不烦，是知其证，非气结而为血结。以其表证误下，尚兼太阳随经之热未尽，故以抵当为至当。若脉数不解而下利不止，乃对“假令已下，脉数不解”五句之文见。已下脉数不解，六七日不大便则宜抵当。若下利不止，又当随其下血不下血而异治。倘血分之热邪不除，必协热而便脓血。○详此条系仲景揣度庸工之设辞，意谓治病，无问表里证，但发热至七八日，虽脉浮数，意谓皆可下之，谓其日数即久，邪气已入于腑，可下而已，非实谓此证有可下。仲景立法之至圣，断无脉浮发热表证表脉而教人可下之理。尚论以为七八日，为时既久，势不得不用下法，殊觉昧昧。
太阳病寸缓关浮尺弱，其人发热汗出，复恶寒，不呕，但心下痞的，这是医生误下所致。如其未下者，病患不恶寒而渴，此转属阳明。小便数者，大便必硬，不更衣，十日无所苦。渴欲饮水，少少与之，但以法救之。渴者宜五苓散。
寸缓关浮尺弱，发热汗出复恶寒，纯是太阳中风未罢之证。设非误下，何得心下痞结耶？如不误下，则心下亦不痞，而太阳证必渐传经，乃至不恶寒而渴，邪入阳明审矣。然阳明津液既随湿热偏渗于小便，则大肠失其润，而大便之硬，与肠中结热自是不同。所以旬日不更衣，亦无所苦。以法救之，去其湿热，救其津液，言与水及用五苓法也。今世用五苓，但知水谷偏注于大肠，用之利水而止泄，至于津液偏渗于小便，用之消渴而回津者，非仲景不能。○更衣言易衣而如厕。
病患烦热，汗出则解，又如疟状，日晡所（下午3-5点）发热者，属阳明。脉实者宜下之，脉浮虚者宜发汗。下之与承气汤，发汗宜桂枝汤。
病患得汗后，烦热解，以太阳经之邪将尽未尽，其人复如疟状，日晡时发热，则邪入阳明审矣。发热即潮热，乃阳明之本候。然虽入阳明，尚恐未离太阳，故必重辨其脉。脉实者，方为阳明腑证，宜下之。若脉浮虚者，仍是阳明而兼太阳经证，更宜汗而不宜下。
阳明病，心下硬满的，不可攻之。攻之利遂不止者死，利止者愈。
心下硬满，邪聚阳明气分，证兼太阳。故不可攻。攻之利不止，则邪气未尽，真气先脱，故死。利止则邪气去，而正气犹存，故愈。
脉浮而大，心下反硬，有热属脏者，攻之不令发汗。
伤寒以脉浮为表证，胸满为阳邪。此脉浮为热气内蒸达表，必五六日后脉反浮大，要非初病表证脉浮之比。心下硬为燥结逆攻，必先腹胀，而后变心下硬，亦非初病阳邪上结之比。故仲景特申之，曰有热属脏，言内有实热，燥屎逆攻脾脏。且戒之曰不令发汗，急当攻之。此所谓证书不凭脉。
属腑者，不入溲数。溲数则大便硬，汗多则热愈，汗少则便难。脉迟尚未可攻。
邪入阳明之腑，必自汗小便多，以其热内结，津液滂渗。是以仲景有阳明病汗多，禁利小便之戒。此热邪虽入阳明而未作里实，犹宜和解，如小柴胡热服亦能出汗。汗多则邪从汗解而热愈，汗少则邪热内结而便难。若脉迟为热尚少，结水定硬，须俟脉数结定然后攻之。○二条旧在脉法篇中，今归此。
太阳病二日而发汗不解，蒸蒸发热者，属胃也，调胃承气汤主之。
本太阳中风，误用麻黄发汗，汗出过多，反伤胃中津液，所以不解。热邪乘虚内入，而为表里之证。蒸蒸者，热则有内胜达于外。惟热在胃，故用承气以调其胃，胃调则病涣然除。
伤寒吐后腹胀满的，与调胃承气汤。
吐后腹满，则邪不在胸，其为里实可知。但腹满而不痛，终属表邪入里未实，故不宜峻下，少与调胃承气和之可也。
阳明病不吐不下，心烦的，可与调胃承气汤。
胃气及津液，既不由吐下而伤，则心烦明系胃中热炽，故可与调胃承气以安胃而全津液。可与者，欲人临病裁酌，不可竟行攻击。
太阳病过经十余日，心下温温欲吐而胸中痛，大便反溏，腹微满，郁郁微烦，先此时自极吐下的，与调胃承气汤。若不尔者，不可与。但欲呕胸中痛微溏者，此非柴胡证而呕，故知极吐下。
太阳病过经十余日，心下温温欲吐而不吐，其人胸中痛，大便反溏，腹微满，郁郁微烦者，此有二辨。若曾经大吐大下……
Question: There are Taiyang Yangming, Zhengyang Yangming, and Shaoyang Yangming. What does this mean?
Answer: Taiyang Yangming refers to the Pi Yue (Spleen Constriction) syndrome. Zhengyang Yangming refers to the Wei Jia Shi (Stomach House Excess) syndrome.
Shaoyang Yangming refers to the condition where, after sweating or promoting urination, the stomach becomes dry, irritable, and excess, leading to difficult defecation.
Pi Yue (Spleen Constriction) occurs because the patient's body fluids were originally depleted. When the pathogenic heat was in the Taiyang channel, defecation was already difficult. Taiyang Yangming means that the pathogenic heat of the Taiyang channel did not wait to resolve but directly entered the Yangming channel and transmitted into the Stomach Fu organ.
Zhengyang Yangming means that the pathogen from the channels transmitted to the Fu organs, with exterior pathogens merging into the interior, hence called Wei Jia Shi (Stomach House Excess).
Shaoyang Yangming occurs after sweating and promoting urination, depleting body fluids, causing dryness, irritability, excess heat in the stomach, and difficult defecation. The Shanglun school incorrectly believes that transmission from the Yangming channel to the Shaoyang channel constitutes Shaoyang Yangming. If a channel pathogen transmits to another channel, the stomach may not necessarily become dry with difficult defecation. If Yangming channel pathology transmits to Shaoyang syndrome, it should be called "Yangming-Shaoyang," not "Shaoyang Yangming."
The general principle of Yangming disease is: Wei Jia Shi (Stomach House Excess).
Question: How does one contract Yangming disease?
Answer: After treating Taiyang disease with sweating, purging, or promoting urination, if body fluids are lost, causing dryness in the stomach, it transforms into Yangming disease. If one does not defecate, there is internal excess and difficult defecation; this is named Yangming disease.
Question: What are the external manifestations of Yangming disease?
Answer: Fever, spontaneous sweating, aversion to cold is absent, but there is aversion to heat.
Question: Some patients develop fever without aversion to cold on the first day. Why?
Answer: Although it has been only one day, any initial aversion to cold will soon cease spontaneously, followed by spontaneous sweating and aversion to heat.
Question: Why does aversion to cold cease spontaneously?
Answer: Because Yangming belongs to Earth in the center, receiving all things, the pathogen does not transmit further. Initially, there may be aversion to cold, but it stops by the second day; this is Yangming disease.
Originally Taiyang disease, when sweating was induced at the onset but was incomplete, it transformed into Yangming disease.
In Cold Damage, if there is fever, no sweat, vomiting, inability to eat, yet suddenly profuse sweating (Ji Ran), this indicates transformation into Yangming disease.
When Cold Damage transforms to involve Yangming, the patient exhibits Ji Ran (continuous) slight sweating.
Once Ji Ran sweating occurs, it can be inferred that the heat is resolved and vomiting stops.
If the pulse is superficially weak (Cun position) and sweating is scant, it indicates self-harmonization. If sweating is excessive, it is an overreaction. If the Yang pulse is solid due to excessive sweating, this is also an overreaction. Overreaction leads to Yang deficiency internally and loss of body fluids, resulting in hard stool.
In Wind Strike, a pulse that is slightly slow and moderate indicates mild wind pathogen; scant sweating is not excessive. In Cold Damage, a pulse reaching solidity indicates the imminent transition from Taiyang to a condition suitable for purging. Moreover, excessive sweating surely causes loss of body fluids and hard stool, transmitting to Yangming.
The above generally discusses the transmission of Yangming Fu syndromes.
Yangming Wind Strike presents with bitter taste, dry throat, abdominal fullness, slight panting, fever, aversion to cold, and a floating-tight pulse. If purged, abdominal fullness worsens and urination becomes difficult.
Although called Yangming Wind Strike, the symptoms show unresolved Taiyang Cold Damage signs. However, based on abdominal fullness, we know heat has entered Yangming. Yet it differs from severe excess/fullness. Mis-purging causes deeper entrapment of pathogens and increased fullness. Difficult urination results from fluid depletion.
In Yangming disease, a slow pulse, inability to eat to satiety, slight irritability and dizziness after eating, and difficult urination indicate impending Gu Dan (Grain Jaundice). Purging will not relieve abdominal fullness because of the slow pulse.
A slow pulse suggests the exterior syndrome is resolving, but postprandial irritability indicates external pathogens aiding internal heat. Dizziness is caused by wind attacking upward. Difficult urination is due to dampness obstructing water passages. Water-dampness steamed by heat causes generalized yellowing. Purging fails to relieve fullness because the slow pulse indicates non-solidity of the stomach; purging only waste harms the body. While Yangming usually requires purging, especially with abdominal pain, this specific case with a slow pulse and empty stomach qi (fluid insufficiency) involves virtual heat obstruction, not solid heat requiring purging. Thus, purging is ineffective. Sweating and diuresis are also ineffective. One should use harmonizing methods, such as Gan Cao Gan Jiang Tang (Licorice and Ginger Decoction) to warm the middle, followed by small amounts of Tiao Wei Cheng Qi Tang (Modify the Stomach and Direct Downward Decoction) to gently harmonize stomach qi.
In Yangming disease, if cold invades the stomach causing inability to eat, difficult urination, and Ji Ran sweating on the hands and feet, this indicates impending Gu Jia (Fixed Mass/Chronic Diarrhea). Defecation will likely be hard initially then loose. This is due to cold in the stomach and failure to separate water and grain.
Prolonged loose stools are called Gu Jia, implying a fixed mass that does not disperse.
In Yangming disease, if the patient desires food, urination is difficult, defecation is normal, bone joints ache, there is a slight feeling of heat, sudden madness occurs, and Ji Ran sweating resolves the condition, this is because the stomach qi could not handle the grain qi, which expelled together with sweat. A tight pulse indicates recovery.
Bone joint pain indicates dampness excess. Slight heat sensation indicates heat excess. The interaction of dampness and heat causes sudden madness and resolution via Ji Ran sweating. Since the patient can eat, stomach qi is strong enough to drive out water and heat from Yangming, preventing them from overwhelming the body. The tight pulse resolves because previous lack of sweating left the pulse tight; now strong stomach qi opens the skin pores, allowing profuse sweating and pulse normalization.
In Yangming disease, inability to eat combined with clearing heat leads to hiccups (Yue) because of cold deficiency in the stomach. Due to underlying deficiency, clearing heat causes hiccups. (Yue refers to hiccups).
With a floating-slow pulse, exterior heat and interior cold presenting as diarrhea of undigested food, Si Ni Tang (Frigid Extremities Decoction) is indicated. If cold deficiency in the stomach prevents eating, drinking water causes hiccups.
Exterior heat and interior cold require rescuing the interior first. Si Ni Tang was used in Taiyang; its use in Yangming is even more appropriate. This case is colder than the previous one; thus, not only does clearing heat cause hiccups, but drinking water also triggers them.
These five clauses discuss stomach qi strength rather than external pathogens. Only "water cannot overcome grain qi, tight pulse indicates recovery" shows strong stomach qi. The other four show slow pulse and cold stomach, overwhelmed by water and heat. Although Cold Damage is typically a heat syndrome, patients with cold-deficient stomachs differ. A cold-deficient stomach mixes water and grain; incoming heat cannot immediately become excess. Non-excess stomach precludes purging; purging would fail to remove water-heat and endanger stomach qi, causing hiccups. Zhang Zhongjing listed these clearly, using Si Ni Tang for diarrhea of undigested food, and warming formulas for milder cases. Patients with deficient stomach qi attract external pathogens that increase heat. Stomach heat affects the Bladder, impairing Qi transformation and urination, leading to clear diarrhea. If urination is impaired, heat seeps into the Spleen, causing yellowing of limbs and body (Gu Dan). Sweating from hands and feet moves Spleen damp-heat, avoiding jaundice, but since sweat is limited, it causes Gu Jia rather than severe diarrhea. Even healthy people suffer if urine stops; certainly, stagnant hot urine in Cold Damage causes these variations.
After severe vomiting and purging in Cold Damage, extreme weakness and profuse sweating occur due to exterior stagnation and giving water to induce sweat, causing hiccups due to stomach cold.
In Cold Damage, hiccups with abdominal fullness require examining the anterior and posterior orifices to identify blockage; relieving the blockage cures it.
One type is stomach qi cold deficiency (treat with warming: Si Ni Tang, Li Zhong Tang); the other is stomach excess heat (treat with draining: Cheng Qi Tang, Wu Ling San).
○ These two clauses were formerly at the end of the Jueyin chapter; now included here.
After six or seven days of illness, with a slow-floating-weak pulse, aversion to wind and cold, and warm hands and feet, if the physician purges two or three times, leading to inability to eat, hypochondriac fullness/pain, yellowing of face/body, stiff neck, and difficult urination, administering Chai Hu Tang will cause heaviness in the rectum. If thirsty and vomiting after drinking water, Chai Hu Tang is contraindicated. Eating causes hiccups.
Six or seven days without high fever but with warm hands indicates pathogen entering interior. Slow-floating-weak pulse keeps pathogen in muscles; aversion to wind remains. Repeated purging traps Taiyang pathogen inward, damaging stomach qi. Hypochondriac fullness resembles Pi (glomus) but isn't. Yellowing, stiff neck, and difficult urination indicate cold-fluid retention above and below. Wu Ling San (Five Ingredient Powder with Poria) should be used to resolve and drain. Mistaking this for Shaoyang and using cold Chai Hu Tang causes rectal heaviness and vomiting/hiccups, signs of fluid loss and stomach cold.
If the patient's pulse is rapid (Shu), indicating heat, digestion should be enhanced, but vomiting occurs instead. This is because sweating weakened Yang qi, causing interior deficiency and a rapid pulse representing transient heat. The stomach is cold-deficient, causing vomiting.
Generally, Yang excess yields rapid pulse, Yin excess yields slow pulse. With weak Yang, why is the pulse rapid? Rapid pulse implies cold stomach; one must seek the cause. Rapid pulse results from misusing acrid-warm dispersants leaving transient heat; stomach cold results from insufficient Yang generating interior cold. Physicians seeing rapid pulse might wrongly use cold purgatives, damaging both upper and lower Yang, leading to a wiry pulse and Fan Wei (regurgitation/vomiting).
In Yangming disease, fever and sweating allow heat to vent outward, preventing jaundice. If only the head sweats, body has no sweat up to the neck, urination is difficult, and thirst drives fluid intake, this is Yu Re Zai Li (Stagnant Heat in the Interior), causing jaundice. Yin Chen Hao Tang (Artemisia Capillaris Decoction) is indicated.
Using Yin Chen Hao Tang for stagnant heat in the interior parallels treatment for Taiyang cold-damp jaundice. The difference is abdominal fullness versus thirst-driven fluid intake; Da Huang (Rhubarb) assists Yin Chen to drain heat and dampness.
In Yangming disease, if the face is entirely red, do not purge. Purging causes fever, yellowing, and difficult urination.
Deficient individuals contracting external pathogens carry deficient fire, reddening the face. In Taiyang, sweating should not be abused; in Yangming, purging is even less appropriate. True Yang deficiency allows rootless fire to rise with exterior medicines (causing dry throat, irritability, cold feet) and fall with interior medicines (causing fever, yellowing, difficult urination).
In Yangming disease, no sweat, difficult urination, and Ao Nao (restlessness) indicate impending jaundice.
Inability to sweat externally and urinate internally traps heat in the chest, steaming the body yellow.
In Yangming disease, if treated with fire therapy, slight sweating on the forehead and difficult urination lead to jaundice.
Considering these four clauses: Yangming disease with damp-stagnation and heat-retention causes irritability and thirst, inevitably leading to jaundice. Sweating vents heat outward, preventing jaundice; frequent urination vents heat downward, preventing jaundice. Mis-purging deepens heat and damages fluids, making sweat and urination impossible. Fire therapy intensifies heat, forcing fluids upward; although forehead sweats slightly, body sweat and urination remain blocked. Jaundice is unavoidable. Jaundice and Gu Dan share origins but differ in etiology (cold stomach vs. heat); they branch from the same source as Gu Jia and hiccups.
In Yangming disease, bleeding from the anus with delirium indicates Re Ru Xue Shi (Heat Entering the Blood Chamber). Head-only sweating is treated by puncturing Qi Men (LR14) to drain excess. Ji Ran sweating indicates recovery.
In women, during menstruation, heat enters the Blood Chamber. In men, Yangming channel bleeding with delirium also indicates Heat Entering the Blood Chamber, always due to heat exploiting deficiency. Post-hematemesis food stagnation with night delirium is also treated as Heat Entering the Blood Chamber. Ming Theory states the Chong Mai is the Blood Chamber; in women, pathogens enter via channels; in men, via Yangming.
In Yangming disease, forgetfulness indicates Xu Xue (Blood Stasis) due to long-standing blood stasis. Stool may be hard but passes easily with black color. Di Dang Tang (Di Dang Decoction) is indicated.
Taiyang heat binding in the Bladder causes mild mania (Tao He Cheng Qi Tang) or severe mania (Di Dang Tang). Yangming forgetfulness is milder than mania but uses Di Dang Tang because Yangming blood is abundant and harder to move than Taiyang blood. Note: Black stool indicates blood stasis (sticky like lacquer) or dry heat accumulation (dull like coal); this distinguishes them.
Patients with no exterior/interior signs, fever for 7-8 days, and floating-rapid pulse may be purged. If purged and pulse remains rapid, combined heat causes hunger. By day 6-7, constipation indicates blood stasis; Di Dang Tang is indicated. If purged and diarrhea persists with rapid pulse, bloody pus in stool occurs.
Although fever and floating-rapid pulse suggest Taiyang, mis-purging draws pathogens inward, causing rapid pulse. Combined exterior-interior pathogens cause hunger. Constipation without irritability indicates blood stasis, not Qi stagnation, due to residual Taiyang heat. Di Dang Tang is appropriate. If diarrhea persists, treat according to presence/absence of blood. Unremoved blood heat causes bloody pus. This clause is hypothetical advice against unskilled physicians who might purge based solely on duration and pulse. Zhang Zhongjing would never advise purging with floating pulse and exterior signs. Shanglun's view that duration necessitates purging is mistaken.
In Taiyang disease, Cun slow, Guan floating, Chi weak pulse with fever, sweating, aversion to cold, no vomiting, but epigastric fullness indicates iatrogenic purging. Without purging, absence of aversion to cold and thirst indicate transformation to Yangming. Frequent urination causes hard stool. Ten days without defecation causes no discomfort. Thirst treated with small sips of water or Wu Ling San (Five Ingredient Powder with Poria) resolves it.
Cun slow, Guan floating, Chi weak pulse with fever, sweating, and aversion to cold indicates unresolved Taiyang Wind Strike. Epigastric fullness results from mis-purging. Without purging, Taiyang transforms to Yangming (no aversion to cold, thirst). Fluids drain to bladder via damp-heat, drying intestines. Hard stool differs from intestinal heat accumulation. Ten days without defecation causes no discomfort. Treatment removes damp-heat and restores fluids using water and Wu Ling San. Modern use of Wu Ling San focuses on stopping diarrhea by directing water to large intestine, missing Zhang Zhongjing's intent to restore fluids by directing water away from bladder.
Patient with irritability and heat resolves with sweating. Recurrence like malaria, afternoon fever (Ri Bu Suo) indicates Yangming. Solid pulse requires purging (Cheng Qi Tang); floating-weak pulse requires sweating (Gui Zhi Tang/Cinnamon Twig Decoction).
After sweating, irritability resolves. Residual Taiyang pathogen causes malaria-like symptoms and afternoon fever (tidal fever), confirming Yangming involvement. Solid pulse confirms Yangming Fu syndrome requiring purging. Floating-weak pulse indicates Yangming with concurrent Taiyang channel syndrome, requiring sweating, not purging.
In Yangming disease, epigastric hardness/fullness prohibits purging. If purged and diarrhea continues endlessly, death ensues; if diarrhea stops, recovery occurs.
Epigastric hardness/fullness involves Yangming Qi level and concurrent Taiyang. Purging exhausts true Qi before eliminating pathogens, causing death. Stopping diarrhea indicates pathogen removal and preserved Qi.
Floating-large pulse with epigastric hardness and heat belonging to Zang organs requires purging, not sweating.
Floating pulse usually indicates exterior syndrome; chest fullness indicates Yang pathogen. Here, floating pulse reflects internal heat steaming outward, appearing days later, unlike initial exterior floating pulse. Epigastric hardness follows abdominal distension, differing from initial Yang pathogen knotting. Zhang Zhongjing emphasizes "heat belonging to Zang," meaning internal solid heat and dry feces attacking Spleen. He warns against sweating, urging immediate purging. This prioritizes symptoms over pulse.
Belonging to Fu organs involves no frequent urination. Frequent urination causes hard stool. Profuse sweating increases heat; scant sweating causes difficult defecation. Slow pulse indicates purging is premature.
Pathogens entering Yangming Fu cause sweating and frequent urination due to internal heat drawing fluids. Zhang Zhongjing warns against diuretics in Yangming with profuse sweating. If heat enters Yangming but hasn't formed solid excess, harmonizing (e.g., Xiao Chai Hu Tang) is suitable. Hot administration induces sweating, resolving heat. Scant sweating traps heat, causing constipation. Slow pulse indicates insufficient heat for solidification; wait for rapid pulse before purging.
○ These two clauses were formerly in Pulse Methods; now moved here.
Taiyang disease on day two, sweating fails to resolve steaming fever, indicating Stomach involvement. Tiao Wei Cheng Qi Tang (Modify the Stomach and Direct Downward Decoction) is indicated.
Original Taiyang Wind Strike treated with Ma Huang Tang (Ephedra Decoction) caused excessive sweating, damaging stomach fluids. Heat entered deficiency, creating exterior-interior syndrome. Steaming heat indicates internal heat reaching exterior. Since heat is in Stomach, Cheng Qi formula harmonizes Stomach, resolving disease.
After vomiting in Cold Damage, abdominal fullness is treated with Tiao Wei Cheng Qi Tang.
Abdominal fullness after vomiting indicates interior excess, not chest pathology. Fullness without pain suggests exterior pathogen entering interior but not fully solid; harsh purging is inappropriate. Small doses of Tiao Wei Cheng Qi Tang harmonize.
In Yangming disease, without prior vomiting or purging, irritability indicates intense stomach heat. Tiao Wei Cheng Qi Tang soothes Stomach and preserves fluids. "Ke Yi" (may be given) advises clinical discretion, not blind aggression.
Taiyang disease persisting over ten days, with epigastric nausea, chest pain, loose stool, mild abdominal fullness, and slight irritability, following extreme vomiting/purging, is treated with Tiao Wei Cheng Qi Tang. Otherwise, it is contraindicated. Nausea, chest pain, and loose stool without history of extreme treatment are not Chai Hu syndrome.
Taiyang disease persisting over ten days, with epigastric nausea (not vomiting), chest pain, loose stool, mild abdominal fullness, and slight irritability, has two differentiations. If preceded by severe vomiting/purging...
