承上编《太阴阳明论》,而更为阳明脉解也。阳明属土,故恶木;阳明热甚,故恶火∶阳明厥逆,故
恶人;四肢实,则登高;热盛则弃衣;不欲食,则妄走。皆阳明经脉之病,有生死虚实之殊,故以为解。
黄帝问曰∶足阳明之脉病,恶人与火,闻木音,则惕然而惊。
钟鼓不为动,闻木音而惊何也?愿闻其故。
恶,去声,下同。《灵枢·经脉》论云∶胃足阳明之脉病,则恶人与火,闻木音则惕然而惊,帝引此以问。
岐伯对曰∶阳明者,胃脉也。胃者土也。故闻木音而惊者,土恶木也。
闻木音而惊者,阳明胃脉属土,土恶木克之义。
帝曰∶善。其恶火何也?岐伯曰∶阳明主肉,其脉血气盛,邪客之则热,热甚则恶火。
其恶火者,阳明主肉,其脉血气皆盛,邪客之,则热甚而恶火也。
帝曰∶其恶人,何也?岐伯曰∶阳明厥,则喘而惋,惋则恶人。
厥,厥逆也。惋,惊顾也。阳明恶人者,胃络之脉,不能上行
外达,则厥逆,厥逆则喘急而惊顾,惊顾则恶人也。
帝曰∶或喘而死者,或喘而生者,何也?
喘惋之证,有死有生,故复问之。
岐伯曰∶厥逆连脏则死,连经则生。
胃络上合心包,旁通支腋,今胃气厥逆,病连少阴之心脏则死,病连心包之经脉则生。
帝曰∶善。病甚,则弃衣而走,登高而歌,或至不食数日,逾
垣上屋,所上之处,皆非其素所能也,病反能者,何也?
阳明病甚,则发狂,故举以问。
岐伯曰∶四肢者,诸阳之本也,阳盛,则四肢实,实则能登高也。
手之三阳,从手走头,足之三阳,从头走足,故四肢者,诸阳之本也,今阳气有余而盛,则充溢四
肢而实,实则能登高也。
帝曰∶其弃衣而走者何也?岐伯曰∶热盛于身,故弃衣而走也。
其弃衣而走者,阳明火热,盛于周身,故弃衣而走也。
帝曰∶其妄言骂詈,不避亲疏而歌者,何也?
詈,音利,下同。登高弃衣,外狂也;妄言骂詈,不避亲疏而歌,内狂也,故复问之。
岐伯曰∶阳盛,则使人妄言骂詈,不避亲疏。
阳气火气也,心之所主也。阳气亢盛,则心主血脉不和,故使人妄言骂詈,不避亲疏而歌也。
而不欲食,不欲食,故妄走也。
上文有不食数日逾垣上屋之问,故言而不欲食,惟不欲食,故
逾垣上屋而妄走也。不欲食而妄走,是四肢禀气于胃,胃以饮食为本之义。
承接上篇《太阴阳明论》,进一步阐释阳明脉的病理变化。阳明经属土,所以厌恶木;阳明热邪炽盛,所以厌恶火;阳明经气厥逆,所以厌恶见人;四肢充实有力,就能登上高处;体内热盛,就会脱去衣物;不想进食,就会胡乱奔跑。这些都是阳明经脉的病变,其中有生死、虚实的不同表现,因此加以解释。
黄帝问道:足阳明经脉发生病变时,会厌恶人和火光,听到木器的声音,就会惊恐不安。
钟鼓的声音不会引起他的反应,为什么听到木器的声音就惊恐呢?希望听听其中的原因。
“恶”读作去声,下文相同。《灵枢·经脉》篇中说:“足阳明胃经发生病变,就会厌恶人和火光,听到木音则惊恐不安”,黄帝引用这段话发问。
岐伯回答说:阳明经,就是胃的经脉。胃在五行中属土。所以听到木器声音就惊恐,是因为土厌恶木的克制。
听到木器声音就惊恐,是因为阳明胃脉属土,体现了土被木克制的含义。
黄帝说:好。那为什么厌恶火光呢?岐伯说:阳明经主管肌肉,其经脉中血气旺盛,邪气侵袭就会产生热象,热势炽盛就会厌恶火光。
之所以厌恶火光,是因为阳明经主管肌肉,其经脉血气皆盛,邪气侵袭后,热势炽盛而厌恶火光。
黄帝说:那为什么厌恶见人呢?岐伯说:阳明经气厥逆,就会出现气喘和心中烦闷惊惧,心中烦闷惊惧就会厌恶见人。
“厥”指厥逆。“惋”指惊顾(惊恐环顾)。阳明经厌恶见人,是因为胃的络脉之气不能上行外达,导致厥逆,厥逆则气喘急促且惊恐环顾,惊恐环顾就会厌恶见人。
黄帝说:有的气喘而死,有的气喘而生,这是为什么呢?
气喘烦闷的病症,有死有生,所以再次询问。
岐伯说:厥逆如果波及内脏就死亡,如果仅波及经络就存活。
胃的络脉向上汇合于心包,旁通腋下支脉。现在胃气厥逆,如果病邪牵连少阴心脏就死亡,如果病邪仅连心包的经脉就存活。
黄帝说:好。病情严重时,会脱去衣服乱跑,登上高处唱歌,甚至几天不吃饭,翻越墙垣爬上屋顶,所去的地方,都是他平时做不到的,病情反而使他能够这样做,是什么原因呢?
阳明病严重时会发狂,所以举出这些症状来询问。
岐伯说:四肢是诸阳经的根本,阳气旺盛,四肢就充实,四肢充实就能登上高处。
手三阳经从手走向头,足三阳经从头走向足,所以四肢是诸阳经的根本。现在阳气有余而旺盛,充满四肢使之充实,四肢充实就能登上高处。
黄帝说:那为什么脱去衣服乱跑呢?岐伯说:因为热邪充斥全身,所以脱去衣服乱跑。
之所以脱去衣服乱跑,是因为阳明火热之邪充斥周身,所以脱去衣服乱跑。
黄帝说:那为什么胡言乱语、骂人,不分亲疏地唱歌呢?
“詈”读作利,下文相同。登高弃衣,是外在的狂态;胡言乱语、骂人,不分亲疏地唱歌,是内在的狂态,所以再次询问。
岐伯说:阳气旺盛,就会使人胡言乱语、骂人,不分亲疏。
阳气即火气,由心所主宰。阳气亢盛,导致心主血脉的功能不和,所以使人胡言乱语、骂人,不分亲疏地唱歌。
并且不想进食,因为不想进食,所以胡乱奔跑。
上文有不食数日、翻墙爬屋的疑问,所以说因为不想进食,正因为不想进食,所以翻墙爬屋并胡乱奔跑。不想进食却胡乱奔跑,说明四肢的气禀受于胃,胃以饮食为本的道理。
Following the previous chapter "Taiyin Yangming Lun" (Treatise on Taiyin and Yangming), this section further explains the pathologies of the Yangming pulse. The Yangming channel belongs to Earth, thus it dislikes Wood; Yangming heat is excessive, thus it dislikes Fire; Yangming Qi rebellion causes aversion to people; when the four limbs are solid, one can climb high; when heat is abundant, one discards clothing; when there is no desire to eat, one runs wildly. These are all diseases of the Yangming channels, differing in life-and-death, deficiency, and excess, hence they are explained.
The Yellow Emperor asked: When the Foot-Yangming channel is diseased, why does one dislike people and fire, and why does hearing the sound of wood cause sudden fright?
The sound of bells and drums does not move him, but why does he startle at the sound of wood? I wish to hear the reason.
"Dislike" (E) is pronounced with the departing tone, as below. The *Ling Shu · Jing Mai* (Spiritual Pivot · Channels) states: "When the Foot-Yangming Stomach channel is diseased, one dislikes people and fire, and hears the sound of wood with sudden fright." The Yellow Emperor cites this to ask.
Qibo replied: The Yangming is the Stomach channel. The Stomach belongs to Earth. Therefore, hearing the sound of wood causes fright because Earth dislikes the control of Wood.
Hearing the sound of wood causes fright because the Yangming Stomach channel belongs to Earth, reflecting the meaning of Earth being controlled by Wood.
The Yellow Emperor said: Good. Why does he dislike fire? Qibo said: Yangming governs the flesh, and its channel has abundant blood and Qi. When pathogens invade, heat arises; when heat is excessive, one dislikes fire.
The reason for disliking fire is that Yangming governs the flesh, and its channel's blood and Qi are abundant. When pathogens invade, heat becomes excessive, leading to a dislike of fire.
The Yellow Emperor said: Why does he dislike people? Qibo said: When Yangming Qi rebels, there is panting and inner distress/fright; due to this inner distress, one dislikes people.
"Rebellion" (Jue) refers to Qi reversal. "Distress/Fright" (Wan) refers to startled looking around. Yangming dislikes people because the collateral vessels of the Stomach cannot ascend and reach the exterior, causing Qi rebellion. Rebellion leads to rapid panting and startled looking, which results in disliking people.
The Yellow Emperor said: Some die from panting, while some survive. Why?
The condition of panting and distress has both fatal and survivable outcomes, so he asks again.
Qibo said: If the rebellion connects to the Zang organs, death ensues; if it connects only to the Jing channels, survival occurs.
The Stomach collaterals connect upward to the Pericardium and pass laterally through the axilla. Now, if Stomach Qi rebels and the disease involves the Shaoyin Heart organ, death occurs; if it involves only the Pericardium channel, survival occurs.
The Yellow Emperor said: Good. In severe cases, one discards clothes and runs, climbs high and sings, or goes several days without eating, climbing over walls and onto roofs. Places climbed are beyond their usual capabilities, yet the disease enables them to do so. What is the reason?
Severe Yangming disease leads to mania, so these symptoms are cited for inquiry.
Qibo said: The four limbs are the root of all Yang channels. When Yang is abundant, the four limbs become solid; when solid, one can climb high.
The Hand-Taiyang channels flow from hands to head, and the Foot-Taiyang channels flow from head to feet; thus, the four limbs are the root of all Yang channels. Now, with excess and abundance of Yang Qi, it fills the four limbs making them solid; when solid, one can climb high.
The Yellow Emperor said: Why discard clothes and run? Qibo said: Because heat is abundant in the body, one discards clothes and runs.
The reason for discarding clothes and running is that Yangming Fire-Heat is abundant throughout the body, leading to discarding clothes and running.
The Yellow Emperor said: Why speak wildly, curse, and sing without regard for intimacy or distance?
"Cursing" (Li) is pronounced Li, as below. Climbing high and discarding clothes is external mania; speaking wildly, cursing, and singing without regard for relationships is internal mania, hence the question.
Qibo said: Abundant Yang Qi causes one to speak wildly, curse, and disregard intimacy.
Yang Qi is Fire Qi, governed by the Heart. When Yang Qi is hyperactive, the Heart's governance of blood vessels becomes disharmonious, causing wild speech, cursing, and singing without regard for relationships.
And there is no desire to eat; because there is no desire to eat, one runs wildly.
Regarding the previous question about going days without eating and climbing walls/roofs, it is stated that because there is no desire to eat, precisely due to this lack of desire, one climbs walls and runs wildly. The combination of no desire to eat and wild running illustrates that the four limbs receive Qi from the Stomach, emphasizing that the Stomach regards food and drink as its foundation.
