(素问至真要大论 附∶病有真假辨)
帝曰∶五味阴阳之用何如?岐伯曰∶辛甘发散为阳,酸苦涌泄为阴,咸味涌泄为阴,淡味渗泄为阳。六者或收或散,
或缓或急,或燥或润,或 或坚,以所利而行之,调其气使其平也。(涌,吐也。泄,泻也。渗泄,利小便及通窍也。辛
甘酸苦咸淡六者之性∶辛主散主润,甘主缓,酸主收主急,苦主燥主坚,咸主 ,淡主渗泄。藏气法时论曰∶辛散,酸
收,甘缓,苦坚,咸 。故五味之用,升而轻者为阳,降而重者为阴,各因其利而行之,则气可调而平矣。涌音 ,如
泉涌也。 ,软同。)帝曰∶非调气而得者,治之奈何?有毒无毒,何先何后?愿闻其道。(非调气,谓病有不因于气而
得者也。王太仆曰∶病生之类有四∶一者始因气动而内有所成,谓积聚 瘕,瘤气瘿气,结核癫痫之类也;二者因气动
而外有所成,谓痈肿疮疡,疣疥疽痔,掉螈浮肿,目赤 疹, 肿痛痒之类也;三者不因气动而病生于内,谓留饮癖食,
饥饱劳损,宿食霍乱,悲恐喜怒,想慕忧结之类也;四者不因气动而病生于外,谓瘴气贼魅,虫蛇蛊毒,蜚尸鬼击,冲
薄坠堕,风寒暑湿,斫射刺割捶朴之类也。凡此四类,有独治内而愈者,有兼治内而愈者,有独治外而愈者,有兼治外
而愈者,有先治内后治外而愈者,有先治外后治内而愈者,有须齐毒而攻击者,有须无毒而调引者。其于或重或轻,或
缓或急,或收或散,或润或燥,或 或坚,用各有所宜也。)岐伯曰∶有毒无毒,所治为主,适大小为制也。(治之之道,
有宜毒者,有不宜毒者,但以所治为主,求当于病而已,故其方之大小轻重,皆宜因病而为之制也。)帝曰∶请言其制。
岐伯曰∶君一臣二,制之小也;君一臣三佐五,制之中也;君一臣三佐九,制之大也。(君臣佐义见下章。)寒者热之,
热者寒之,治寒以热,治热以寒,此正治法也。)微者逆之,甚者从之,(病之微者,如阳病则热,阴病则寒,真形易见,
其病则微,故可逆之,逆即上文之正治也。病之甚者,如热极反寒,寒极反热,假证难辨,其病则甚,故当从之,从即
下文之反治也。王太仆曰∶夫病之微小者,犹人火也,遇草而KT ,得木而燔,可以湿伏,可以水灭,故逆其性气以折
之攻之。病之太甚者,犹龙火也,得湿而焰,遇水而燔,不知其性,以水折之,适足以光焰诣天,物穷方止矣;识其性
者,反常之理,以火逐之,则燔灼自消,焰火扑灭。然逆之,谓以寒攻热,以热攻寒。从之,谓攻以寒热,须从其性用,
不必皆同。是以下文曰∶逆者正治,从者反治,从少从多,观其事也。此之谓乎。)坚者削之,客者除之,劳者温之,结
者散之,留者攻之,燥者濡之,急者缓之,散者收之,损者益之,逸者行之,惊者平之,上之下之,摩之浴之,薄之劫
之,开之发之,适事为故。(温之,温养之也。逸者,奔逸溃乱也。行之,行其逆滞也。平之,安之也。上之,吐之也。
摩之,按摩之也。薄之,追其隐藏也。劫之,夺其强盛也。适事为故,适当其所事之故也。)帝曰∶何谓逆从?岐伯曰∶
逆者正治,从者反治,从少从多,观其事也。(以寒治热,以热治寒、逆其病者,谓之正治。以寒治寒,以热治热,从其
病者,谓之反治。从少谓一同而二异,从多谓二同而一异,必观其事之轻重而为之增损。然则宜于全反者,自当尽同无
疑矣。愚按∶治有逆从者,以病有微甚;病有微甚者,以证有真假也。寒热有真假,虚实亦有真假,真者正治,知之无
难,假者反治,乃为难耳。如寒热之真假者,真寒则脉沉而细,或弱而迟,为厥逆,为呕吐,为腹痛,为飧泄下利,为
小便清频,即有发热,必欲得衣,此浮热在外而沉寒在内也。真热则脉数有力,滑大而实,为烦燥喘满,为声音壮厉,
或大便秘结,或小水赤涩,或发热掀衣,或胀疼热渴。此皆真病,真寒者宜温其寒,真热者直解其热,是当正治者也。
至若假寒者,阳证似阴,火极似水也,外虽寒而内则热,脉数而有力,或沉而鼓击,或身寒恶衣,或便热秘结,或烦渴
引饮,或肠垢臭秽,此则恶寒非寒,明是热证,所谓热极反兼寒化,亦曰阳盛隔阴也。假热者,阴证似阳,水极似火也,
外虽热而内则寒,脉微而弱,或数而虚,或浮大无根,或弦芤断续,身虽炽热而神则静,语虽谵妄而声则微,或虚狂起
倒而禁之即止,或蚊迹假斑而浅红细碎,或喜冷水而所用不多,或舌胎面赤而衣被不撤,或小水多利,或大便不结,此
则恶热非热,明是寒证,所谓寒极反兼热化,亦曰阴盛隔阳也。此皆假病,假寒者清其内热,内清则浮阴退舍矣;假热
者温其真阳,中温则虚火归原矣,是当从治者也。又如虚实之治,实则泻之,虚则补之,此不易之法也。然至虚有盛候,
则有假实矣;大实有羸状,则有假虚矣。总之,虚者正气虚也,为色惨形疲,为神衰气怯,或自汗不收,或二便失禁,
或梦遗精滑,或呕吐隔塞,或病久攻多,或气短似喘,或劳伤过度,或暴困失志,虽外证似实而脉弱无神者,皆虚证之
当补也。实者邪气实也,或外闭于经络,或内结于脏腑,或气壅而不行,或血留而凝滞,必脉病俱盛者,乃实证之当攻
也。然而虚实之间,最多疑似,有不可不辨其真耳。如通评虚实论曰∶邪气盛则实,精气夺则虚。此虚实之大法也。设
有人焉,正已夺而邪方盛者,将顾其正而补之乎?抑先其邪而攻之乎?见有不的,则死生系之,此其所以宜慎也。夫正
者本也,邪者标也。若正气既虚,则邪气虽盛,亦不可攻,盖恐邪未去而正先脱,呼吸变生,则措手无及。故治虚邪者,
当先顾正气,正气存则不致于害。且补中自有攻意,盖补阴即所以攻热,补阳即所以攻寒,世未有正气复而邪不退者,
亦未有正气竭而命不倾者。如必不得已,亦当酌量缓急,暂从权宜,从少从多,寓战于守斯可矣,此治虚之道也。若正
气无损者,邪气虽微,自不宜补,盖补之则正无与而邪反盛,适足以借寇兵而资盗粮。故治实证者,当直去其邪,邪去
则身安,但法贵精专,便臻速效,此治实之道也。要之,能胜攻者,方是实证,实者可攻,何虑之有?不能胜攻者,便
是虚证,气去不返,可不寒心。此邪正之本末,有不可不知也。惟是假虚之证不多见,而假实之证最多也;假寒之证不
难治,而假热之治多误也。然实者多热,虚者多寒。如丹溪曰∶气有余,便是火,故实能受寒。而余续之曰∶气不足,
便是寒,故虚能受热。世有不明真假本末而曰知医者,余则未敢许也。)帝曰∶反治何谓?岐伯曰∶热因寒用,寒因热用,
塞因塞用,通因通用,必伏其所主而先其所因,其始则同,其终则异,可使破积,可使溃坚,可使气和,可使必已。(此
节从王氏及新校正等注云∶热因寒用者,如大寒内结,当治以热,然寒甚格热,热不得前,则以热药冷服,下嗌之后,
冷体即消,热性便发,情且不违,而致大益,此热因寒用之法也。寒因热用者,如大热在中,以寒攻治则不入,以热攻
治则病增,乃以寒药热服,入腹之后,热气即消,寒性遂行,情且协和,而病以减,此寒因热用之法也。如五常政大论
云∶治热以寒,温而行之;治寒以热,凉而行之。亦寒因热用、热因寒用之义。塞因塞用者,如下气虚乏,中焦气壅,
欲散满则更虚其下,欲补下则满甚于中。治不知本而先攻其满,药入或减,药过依然,气必更虚,病必渐甚。乃不知少
服则资壅,多服则宣通,峻补其下以疏启其中,则下虚自实,中满自除,此塞因塞用之法也。通因通用者,如大热内蓄,
或大寒内凝,积聚留滞,泻利不止,寒滞者以热下之,热滞者以寒下之,此通因通用之法也。以上四治,必伏其所主者,
制病之本也。先其所因者,求病之由也。既得其本而以真治真,以假治假,其始也类治似同,其终也病变则异矣,是为
反治之法,故可使破积溃坚,气和而病必已也。塞,入声。)帝曰∶善。气调而得者何如?岐伯曰∶逆之从之,逆而从之,
从而逆之,疏气令调,则其道也。(气调而得者,言气调和而偶感于病,则或因天时,或因意料之外者也。若其治法,亦
无过逆从而已,或可逆者,或可从者,或先逆而后从者,或先从而后逆者,但疏其邪气而使之调和,则治道尽矣。)
《素问·至真要大论》附:辨别疾病的真假
黄帝问道:五味在阴阳作用方面是如何区分的?岐伯回答说:辛味和甘味具有发散的作用,属于阳;酸味和苦味具有涌吐和泄下的作用,属于阴;咸味具有涌吐和泄下的作用,属于阴;淡味具有渗湿利窍的作用,属于阳。这六味药性,有的收敛,有的发散,有的缓和,有的急迫,有的燥湿,有的软坚,应当根据它们对机体的有利作用而加以运用,调理气机,使其恢复平衡。(涌,指呕吐。泄,指泻下。渗泄,指通利小便及疏通孔窍。辛、甘、酸、苦、咸、淡六种药性的特性:辛主发散、主滋润,甘主缓和,酸主收敛、主急迫,苦主燥湿、主坚阴,咸主软坚,淡主渗泄。《藏气法时论》说:辛能发散,酸能收敛,甘能缓急,苦能坚阴,咸能软坚。所以五味的功用,升浮而轻清的属于阳,沉降而重浊的属于阴,各自顺应其特性而运用,那么气机就可以调和而平复了。涌音yǒng,像泉水涌出一样。软,同“软”。)
黄帝问道:如果不是通过调气而治愈的,该怎么治疗呢?有毒和无毒的药物,应该先用哪种,后用哪种?希望听听其中的道理。(所谓非调气,是指疾病不是由气机失调引起的。王冰注解说:疾病产生的类别有四种:一是起初因气机运动而在体内形成病变,如积聚、瘕聚、瘤气、瘿气、结核、癫痫之类;二是因气机运动而在体表形成病变,如痈肿疮疡、疣、疥、疽、痔、抽搐、浮肿、目赤、斑疹、肿痛瘙痒之类;三是不因气机运动而在体内产生疾病,如留饮、癖食、饥饱劳损、宿食、霍乱、悲恐喜怒、思慕忧结之类;四是不因气机运动而在体外产生疾病,如瘴气、贼魅、虫蛇蛊毒、飞尸鬼击、冲撞、轻薄、坠落、跌打损伤、风寒暑湿、砍射刺割、捶打压迫之类。凡此四类,有只治内而痊愈的,有内外兼治而痊愈的,有只治外而痊愈的,有内外兼治而痊愈的,有先治内后治外而痊愈的,有先治外后治内而痊愈的,有需要利用药物的毒性来攻伐的,有需要利用无毒药物来调理引导的。其中或重或轻,或缓或急,或收或散,或润或燥,或软或坚,用药各有适宜之处。)
岐伯回答说:无论有毒无毒,都以所治疗的疾病为主,根据病情的大小来制定方剂的剂量。(治疗的方法,有适合用有毒药物的,有不适合用有毒药物的,但都以治疗疾病为主,求得与病情相符合罢了,所以方剂的大小轻重,都应当依据病情来制定。)
黄帝道:请讲讲方剂的制度。
岐伯道:君药一味,臣药两味,这是小方;君药一味,臣药三味,佐药五味,这是中方;君药一味,臣药三味,佐药九味,这是大方。(君臣佐使的含义见下一章。)寒证用热药治疗,热证用寒药治疗,治寒以热,治热以寒,这是正治法。(病势轻微的,逆其病性治疗;病势严重的,顺从病性治疗。(病势轻微的,如阳病则热,阴病则寒,真象容易见到,病情较轻,所以可以逆其病性治疗,逆即上文所说的正治。病势严重的,如热极反现寒象,寒极反现热象,假象难以辨别,病情较重,所以应当顺从病性治疗,从即下文所说的反治。王冰注解说:病势微小的,就像人的火,遇到草就燃烧,遇到木头就烧得更旺,可以用湿气压制它,用水扑灭它,所以逆着它的性质去折服它、攻击它。病势太严重的,就像龙火,遇水反而燃烧,不知其性质,用水去扑灭,只会让火焰冲天,直到燃料耗尽才停止;认识其性质的,违背常理,用火去驱逐它,那么燃烧自会消除,火焰自然扑灭。然而逆之,是指用寒药攻热,用热药攻寒。从之,是指用寒热药攻邪,必须顺从其性质使用,不必完全相同。所以下文说:逆者正治,从者反治,从少从多,观察具体情况。说的就是这个意思。)坚硬的要削磨它,外邪侵袭的要祛除它,虚劳的要温养它,郁结的要消散它,停滞的要攻逐它,干燥的要滋润它,拘急的要舒缓它,耗散的要收敛它,亏损的要补益它,逸游过度的要行气疏导它,惊悸的要平复它,病位在上的要催吐,病位在下要通便,按摩它,洗浴它,逼退它,劫夺它,开泄它,发汗它,以恰当处理为原则。(温之,指温养。逸者,指奔逸溃乱。行之,指行其逆滞之气。平之,指安之。上之,指吐之。摩之,指按摩。薄之,指追逼其隐藏的病邪。劫之,指劫夺其强盛的病势。适事为故,指适当其所处理的事情原则。)
黄帝道:什么叫逆从?
岐伯道:逆者叫正治,从者叫反治,从少从多,要观察病情的具体情况。(用寒药治热病,用热药治寒病,逆着病性治疗,叫做正治。用寒药治寒病,用热药治热病,顺着病性治疗,叫做反治。从少指一方中主要药性与病性相同,次要药性不同;从多指一方中主要药性与病性不同,次要药性相同,必须观察病情的轻重来决定增减。然而如果适合完全反治的,自然应当全部相同,没有疑问。我按语:治疗有逆从之分,是因为病有微甚;病有微甚,是因为证有真假。寒热有真假,虚实也有真假,真证正治,知道这一点不难,假证反治,这才难。比如寒热的真假:真寒则脉沉细,或弱迟,出现厥逆、呕吐、腹痛、完谷不化的泄泻、小便清长频数,即使有发热,也一定想穿衣服,这是浮热在外而沉寒在内。真热则脉数有力,滑大而实,出现烦躁喘满、声音壮厉,或者大便秘结、小便赤涩,或者发热掀衣、腹胀疼痛口渴。这些都是真病,真寒者宜温其寒,真热者直解其热,这是应当正治的。至于假寒,是阳证似阴,火极似水,外表虽寒而内里则热,脉数有力,或沉而鼓指,或身寒恶衣,或大便热秘,或烦渴引饮,或肠垢臭秽,这说明恶寒并非真寒,明明是热证,所谓热极反兼寒化,也叫阳盛格阴。假热,是阴证似阳,水极似火,外表虽热而内里则寒,脉微弱,或数而虚,或浮大无根,或弦芤断续,身体虽然炽热但神志安静,说话虽然谵妄但声音微弱,或者虚狂起倒但制止后即止,或者蚊迹假斑且浅红细碎,或者喜欢冷水但用量不多,或者舌苔面赤但衣被不撤,或者小便多利,或者大便不结,这说明恶热并非真热,明明是寒证,所谓寒极反兼热化,也叫阴盛格阳。这些都是假病,假寒者清其内热,内热清了则浮阴退去;假热者温其真阳,中焦温暖了则虚火归原,这是应当从治的。又如虚实的治法,实则泻之,虚则补之,这是不变的原则。然而至虚有盛候,则有假实;大实有羸状,则有假虚。总之,虚是正气虚,表现为面色惨淡、形体疲惫、神衰气怯,或者自汗不收,或者二便失禁,或者梦遗精滑,或者呕吐膈塞,或者病久攻伐过多,或者气短似喘,或者劳伤过度,或者暴困失志,虽然外证似实但脉弱无神的,都是虚证应当补益。实是邪气实,或者外闭于经络,或者内结于脏腑,或者气壅不行,或者血留凝滞,必须脉病俱盛的,才是实证应当攻伐。然而虚实之间,最多疑似,有不可不辨明真伪的。如《通评虚实论》说:邪气盛则实,精气夺则虚。这是虚实的大法。假如有人,正气已夺而邪气正盛,是顾护正气而补之呢?还是先祛邪气而攻之呢?见解如果不确切,生死就系于此,这就是为什么应当谨慎的原因。夫正者是本,邪者是标。如果正气既虚,那么邪气虽盛,也不可攻伐,恐怕邪气未去而正气先脱,呼吸间发生变故,就来不及措手了。所以治疗虚邪,应当先顾护正气,正气存在就不会受害。而且补中自有攻意,补阴就是用来攻热,补阳就是用来攻寒,世上没有正气恢复而邪气不退的,也没有正气竭尽而性命不倾覆的。如果不得已,也应当斟酌缓急,暂时权宜,从少从多,寓战于守就可以了,这是治疗虚证的方法。如果正气无损,邪气虽微,也不宜补,因为补之则正气无所助而邪气反而盛,正好是给寇兵送武器、给盗贼送粮食。所以治疗实证,应当直接去除邪气,邪去则身安,只是方法贵在精专,便能达到速效,这是治疗实证的方法。总之,能胜任攻伐的,才是实证,实者可攻,有什么可忧虑的?不能胜任攻伐的,便是虚证,气去不返,能不令人寒心吗。这是邪正的本末,有不可不知道的。只是假虚的证候不多见,而假实的证候最多;假寒的证候不难治,而假热的证候多误治。然而实者多热,虚者多寒。如朱丹溪说:气有余,便是火,所以实证能承受寒凉。而我接着说:气不足,便是寒,所以虚证能承受温热。世间有不明真假本末却自称懂医的人,我不敢苟同。)
黄帝道:反治是什么意思?
岐伯道:热因寒用,寒因热用,塞因塞用,通因通用,必须制服其主要病因而先探求其病因,开始用药性质似乎相同,最终效果却不同,这样可以破除积滞,溃散坚结,调和气机,使疾病必愈。(这一节引用王冰及新校正等注释说:热因寒用,如大寒凝结在内,当用热药治疗,但寒甚格拒热药,热药不能进入,就用热药冷服,咽下之后,冷体消散,热性便发挥,情势上不违逆,而获得大益,这是热因寒用的方法。寒因热用,如大热在中,用寒药攻治则不入,用热药攻治则病增,于是用寒药热服,入腹之后,热气消散,寒性遂行,情势协和,而病减,这是寒因热用的方法。如《五常政大论》说:治热以寒,温而行之;治寒以热,凉而行之。也是寒因热用、热因寒用的意义。塞因塞用,如下焦气虚匮乏,中焦气机壅滞,想要消散中满则会更虚下焦,想要补益下焦则中满更甚。治疗不知根本而先攻其满,药入或许减轻,药过依然如故,气必更虚,病必渐重。于是不知道少服则资助壅滞,多服则宣通,峻补下焦以疏启中焦,则下虚自实,中满自除,这是塞因塞用的方法。通因通用,如大热内蓄,或大寒内凝,积聚留滞,泻利不止,寒滞者用热药下之,热滞者用寒药下之,这是通因通用的方法。以上四种治法,必须伏其所主,是制病的根本。先其所因,是求病的由来。既然得其根本而以真治真,以假治假,开始时看似同类相似,最终病变则不同,这就是反治之法,所以可以破积溃坚,气和而病必愈。塞,读入声。)
黄帝道:好。通过调气而治愈的又是怎样的呢?
岐伯道:逆之从之,逆而从之,从而逆之,疏泄气机使其调和,就是治疗的原则。(所谓气调而得,是说气机调和而偶然感病,则或因天时,或因意料之外。至于治疗方法,也不过是逆治和从治而已,或者可以逆治,或者可以从治,或者先逆后从,或者先从后逆,只要疏泄邪气使之调和,那么治道就完备了。)
*Suwen: Zhizhen Yao Dalun* (On the Most Essential and Necessary Principles of the Yellow Emperor's Inner Canon) Appendix: Differentiating True and False Manifestations of Disease
The Yellow Emperor asked: How are the functions of the Five Flavors distinguished in terms of Yin and Yang? Qibo replied: Pungent and Sweet flavors have a dispersing function, which belongs to Yang; Sour and Bitter flavors have an emetic and purgative function, which belongs to Yin; Salty flavor has an emetic and purgative function, which belongs to Yin; Bland flavor has a damp-draining and orifice-unblocking function, which belongs to Yang. These six flavors may either astringe or disperse, either moderate or accelerate, either dry or moisten, either soften or harden. One should act according to their beneficial effects to regulate Qi and restore balance. (Emesis refers to vomiting. Purging refers to defecation. Damp-draining refers to promoting urination and unblocking orifices. The characteristics of the six flavors—Pungent, Sweet, Sour, Bitter, Salty, and Bland—are as follows: Pungent governs dispersion and moistening; Sweet governs moderation; Sour governs astringency and acceleration; Bitter governs drying and hardening; Salty governs softening; Bland governs damp-draining. *Zangqi Fashi Lun* states: Pungent disperses, Sour astringes, Sweet moderates, Bitter hardens, Salty softens. Therefore, among the functions of the Five Flavors, those that ascend and are light belong to Yang, while those that descend and are heavy belong to Yin. Acting in accordance with their respective properties allows Qi to be regulated and balanced. "Yong" sounds like yǒng, like water gushing forth. "Ruan" is synonymous with soft.)
The Yellow Emperor asked: For conditions not cured by regulating Qi, how should they be treated? Regarding toxic and non-toxic substances, which should be used first and which later? I wish to hear the principles. (Non-Qi-regulation refers to diseases not caused by Qi dysfunction. Wang Bing noted: There are four categories of disease origin: First, internal formations resulting from Qi movement, such as accumulations, masses, tumors, goiters, tubercles, and epilepsy; Second, external formations resulting from Qi movement, such as carbuncles, sores, ulcers, warts, scabies, gangrene, hemorrhoids, convulsions, edema, red eyes, rashes, swelling, pain, and itching; Third, internal diseases not caused by Qi movement, such as retained fluids, food stagnation, damage from hunger/fullness or overwork, leftover food, cholera, sorrow/fear/anger/happiness, longing/worry/knotting; Fourth, external diseases not caused by Qi movement, such as miasma, malevolent spirits, insect/snake/poisonous worm toxins, flying corpses, ghost strikes, collisions, falls, wind/cold/damp-heat, cuts/stabbing/cutting/blows/compression. Of these four categories, some heal by treating only internally, some by treating both internally and externally, some by treating only externally, some by treating both, some by treating internally then externally, some by treating externally then internally, some require the use of toxic substances for attack, and some require non-toxic substances for regulation. In each case, whether heavy or light, slow or fast, astringent or dispersing, moistening or drying, softening or hardening, the choice of medication must be appropriate.)
Qibo replied: Whether toxic or non-toxic, the treatment should be primarily directed at the disease being treated, and the dosage should be adjusted according to the size/severity of the condition. (In treatment, there are cases suitable for toxic substances and cases unsuitable for them. The primary goal is to treat the disease appropriately. Therefore, the size and weight of prescriptions should be formulated according to the disease.)
The Yellow Emperor said: Please explain the system of prescription formulation.
Qibo said: One Sovereign herb and two Ministers constitute a small formula; one Sovereign, three Ministers, and five Assistants constitute a medium formula; one Sovereign, three Ministers, and nine Aides constitute a large formula. (The meaning of Sovereign, Minister, Assistant, and Courier is discussed in the next chapter.) Cold conditions are treated with Heat methods; Heat conditions are treated with Cold methods. Treating cold with heat and heat with cold is the method of Direct Treatment (Zheng Zhi). (For mild conditions, oppose the nature of the disease; for severe conditions, follow the nature of the disease. (Mild conditions, such as Yang disease presenting with heat or Yin disease presenting with cold, show true manifestations easily, so the disease is mild and can be treated by opposing its nature. Opposing is the Direct Treatment mentioned above. Severe conditions, such as extreme heat presenting with cold signs or extreme cold presenting with heat signs, present false manifestations that are hard to distinguish, so the disease is severe and should be treated by following its nature. Following is the Indirect Treatment (Fan Zhi) mentioned below. Wang Bing noted: Mild diseases are like human fire; encountering grass it burns, encountering wood it flares up. It can be subdued by dampness and extinguished by water. Thus, one opposes its nature to subdue and attack it. Severe diseases are like dragon fire; encountering moisture it flames, encountering water it burns. If one does not understand its nature and tries to extinguish it with water, the flames will only reach the sky until the fuel is exhausted. Those who understand its nature act against common sense, using fire to drive it away, causing the burning to self-extinguish and the flames to be quenched. However, "opposing" means attacking heat with cold and cold with heat. "Following" means attacking with cold or heat, but one must follow its nature in usage, not necessarily being identical. Hence, the text says: Opposing is Direct Treatment, Following is Indirect Treatment. Follow less or follow more, observing the circumstances. This is what is meant.) Hardness is reduced by scraping; invaders are removed by expulsion; exhaustion is warmed by tonification; knotting is scattered by dissipation; retention is attacked by purging; dryness is moistened by lubrication; tension is eased by relaxing; scattering is gathered by astringing; loss is benefited by tonifying; leisure is promoted by moving; fright is calmed by pacifying; conditions above are treated by inducing vomiting; conditions below are treated by purging; massage is applied; bathing is used; pressure is exerted to trap; drastic measures are taken to劫夺 (seize/rob); opening is performed; sweating is induced. All actions should be appropriate to the situation. (Warming refers to nourishing with warmth. Leisure refers to erratic and chaotic movement. Moving refers to circulating stagnant Qi. Pacifying refers to calming. Above refers to vomiting. Massage refers to manual therapy. Pressure refers to pursuing hidden pathogens. Seizing refers to overcoming strong pathogenic factors. Appropriate to the situation means acting suitably to the specific circumstance.)
The Yellow Emperor asked: What do you mean by Opposing and Following?
Qibo said: Opposing is Direct Treatment; Following is Indirect Treatment. Follow less or follow more, depending on the observation of the situation. (Treating heat with cold and cold with heat, opposing the disease's nature, is called Direct Treatment. Treating cold with cold and heat with heat, following the disease's nature, is called Indirect Treatment. "Follow less" means one similarity and two differences; "Follow more" means two similarities and one difference. One must observe the severity of the condition to adjust additions and reductions. However, if full Indirect Treatment is indicated, one should naturally follow all similarities without doubt. My commentary: Treatment involves Opposing and Following because diseases vary in severity. Severity varies because symptoms have true and false aspects. Cold and Heat have true and false aspects; Deficiency and Excess also have true and false aspects. True conditions are treated directly, which is not difficult. False conditions require Indirect Treatment, which is difficult. For example, regarding the true/false nature of Cold/Heat: True Cold presents with deep, fine, weak, or slow pulses,厥逆 (cold limbs), vomiting, abdominal pain, undigested stool diarrhea, clear and frequent urination. Even if fever occurs, the patient desires clothing. This indicates floating heat on the exterior and sinking cold within. True Heat presents with rapid, forceful, slippery, large, and solid pulses, restlessness, panting, fullness, loud voice, constipation, or dark/scanty urine, fever pushing off clothes, abdominal distension/pain/thirst. These are true diseases. True Cold requires warming the cold; True Heat requires clearing the heat. This is Direct Treatment. As for False Cold, Yang conditions resemble Yin, extreme fire resembles water. Although the exterior feels cold, the interior is hot. Pulses are rapid and forceful, or deep and striking. The body feels cold and dislikes clothing, or stool is hot and constipated, or there is irritability/thirst/drinking, or intestinal discharge is foul-smelling. This indicates that aversion to cold is not true cold but clearly a Heat condition, known as "extreme heat assuming cold transformation," also called "Yang excess blocking Yin." False Heat, Yin conditions resemble Yang, extreme water resembles fire. Although the exterior feels hot, the interior is cold. Pulses are faint and weak, or rapid but empty, or floating and large without root, or wiry and hollow/intermittent. The body is intensely hot but the spirit is quiet; speech is delirious but the voice is weak; or there is virtual mania/restlessness that stops when restrained; or mosquito-bite-like spots that are pale red and fragmented; or preference for cold water but drinking little; or red tongue coating but keeping clothes/blankets on; or frequent urination; or loose stools. This indicates that aversion to heat is not true heat but clearly a Cold condition, known as "extreme cold assuming heat transformation," also called "Yin excess blocking Yang." These are false conditions. For False Cold, clear the internal heat; once internal heat is cleared, floating Yin retreats. For False Heat, warm the true Yang; once the middle is warmed, deficient fire returns to its source. This is Indirect Treatment. Regarding Deficiency/Excess treatment: Excess is drained, Deficiency is tonified. This is an unchanging principle. However, extreme Deficiency may present with Excess symptoms (False Excess); extreme Excess may present with Deficient symptoms (False Deficiency). In summary, Deficiency is a lack of Zheng Qi (Upright Qi), manifesting as pale complexion, fatigue, weak spirit, shortness of breath, spontaneous sweating, incontinence, seminal emission, vomiting/blockage, prolonged illness with excessive treatment, shortness of breath resembling asthma, overwork, sudden exhaustion/loss of will. Although external symptoms resemble Excess, if the pulse is weak and spiritless, it is a Deficient condition requiring tonification. Excess is an abundance of Xie Qi (Pathogenic Qi), either blocking meridians externally or knotting in organs internally, Qi stagnation, or blood stasis. Only when both pulse and symptoms are robust is it an Excess condition requiring attack. However, Deficiency and Excess are often similar and confusing, requiring careful differentiation of truth. As *Tongping Xu Shi Lun* states: "When pathogenic Qi is abundant, it is Excess; when essence and Qi are depleted, it is Deficiency." This is the general rule for Deficiency and Excess. Suppose a person whose Zheng Qi is depleted but Xie Qi is currently abundant: Should one protect Zheng Qi and tonify, or first attack Xie Qi? If judgment is inaccurate, life and death depend on it, hence caution is required. Zheng is the root; Xie is the branch. If Zheng Qi is already deficient, even if Xie Qi is abundant, one must not attack, lest Zheng Qi collapse before Xie Qi is expelled, leading to sudden changes that cannot be handled. Therefore, in treating Deficiency with Pathogens, one must first protect Zheng Qi. If Zheng Qi exists, harm will not occur. Moreover, tonification contains the intent of draining; tonifying Yin drains Heat, tonifying Yang drains Cold. There is no case where Zheng Qi recovers yet Xie Qi remains, nor where Zheng Qi exhausts yet life is preserved. If absolutely necessary, one must weigh urgency, temporarily adopt expedients, follow less or more, and embed attack within defense. This is the way to treat Deficiency. If Zheng Qi is undamaged, even slight Xie Qi should not be treated with tonification, for tonifying would aid Zheng without helping it, allowing Xie Qi to flourish, effectively giving weapons to bandits and grain to thieves. Thus, for Excess conditions, one should directly remove Xie Qi. Once Xie is gone, the body is safe. Methods must be precise and focused for rapid effect. This is the way to treat Excess. Ultimately, only those capable of withstanding attack are Excess conditions; Excess can be attacked, why worry? Those incapable of withstanding attack are Deficient conditions; if Qi departs and does not return, one should be terrified. This is the fundamental distinction between Xie and Zheng, which must be known. False Deficiency is rare, while False Excess is common. False Cold is easy to treat, while False Heat is often misdiagnosed. Generally, Excess involves Heat, and Deficiency involves Cold. Zhu Danxi said: "Excess Qi becomes Fire," thus Excess can tolerate Cold. I add: "Deficient Qi becomes Cold," thus Deficiency can tolerate Heat. I dare not endorse those who claim to understand medicine without distinguishing the true/false and root/branch.)
The Yellow Emperor asked: What is meant by Indirect Treatment?
Qibo said: Heat treated with Cold administration, Cold treated with Heat administration, Obstruction treated with Obstruction methods, Diarrhea treated with Draining methods. One must subdue the primary cause and address the etiology first. Initially, the approach seems similar, but ultimately differs. This can break down accumulations, dissolve hardness, harmonize Qi, and ensure cure. (This section cites notes from Wang Bing and New Corrections: "Heat treated with Cold administration": For example, severe cold knotting internally requires Heat treatment. However, if cold is severe and repels Heat, preventing Heat from entering, one administers Hot medicines Cold. After swallowing, the cold temperature dissipates, and the hot nature activates. The patient's sensation does not conflict, yielding great benefit. This is the method of Heat treated with Cold administration. "Cold treated with Heat administration": For example, severe heat in the center cannot be entered by Cold medicines, and Heat medicines would increase the disease. Thus, Cold medicines are administered Hot. After entering the abdomen, the heat dissipates, and the cold nature acts. The sensation harmonizes, and the disease decreases. This is the method of Cold treated with Heat administration. As *Wuchang Zheng Da Lun* states: "Treat Heat with Cold, administer warmly; treat Cold with Heat, administer coolly." This also embodies the meaning of Cold treated with Heat administration and Heat treated with Cold administration. "Obstruction treated with Obstruction": For example, lower Qi deficiency with middle Jiao Qi stagnation. To scatter fullness would further deplete the lower; to tonify the lower would worsen middle fullness. If treatment ignores the root and attacks fullness first, medicine may reduce symptoms temporarily, but upon cessation, Qi becomes more deficient, and the disease worsens. One must realize that small doses nourish stagnation, while large doses promote circulation. Tonifying the lower severely to open the middle results in lower deficiency becoming solid and middle fullness resolving. This is the method of Obstruction treated with Obstruction. "Diarrhea treated with Draining": For example, internal accumulation of severe Heat or severe Cold, with stagnation and persistent diarrhea. For Cold stagnation, use Hot purgatives; for Heat stagnation, use Cold purgatives. This is the method of Diarrhea treated with Draining. For these four treatments, one must subdue the primary cause (the root of the disease) and address the etiology (the origin of the disease). Having obtained the root, one treats the true with the true and the false with the false. Initially, the treatment appears similar, but ultimately, the pathology changes differently. This is the method of Indirect Treatment, capable of breaking accumulations, dissolving hardness, harmonizing Qi, and ensuring cure. "Se" is pronounced with the entering tone.)
The Yellow Emperor said: Excellent. How about conditions cured by regulating Qi?
Qibo said: Opposing and Following, Opposing then Following, Following then Opposing. Unblocking Qi to achieve harmony is the principle. (Conditions cured by regulating Qi refer to situations where Qi is harmonious but disease occurs occasionally due to seasonal changes or unexpected factors. The treatment methods do not exceed Opposing and Following. Whether one can Oppose or Follow, or Oppose then Follow, or Follow then Oppose, as long as pathogenic Qi is unblocked and harmonized, the therapeutic principle is complete.)
