《素问·阳明脉解篇》帝曰∶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？岐伯曰∶阳明者胃脉也，胃者土也，故闻木音而惊者，土恶木也。帝曰∶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。帝曰∶其恶人何也？岐伯曰∶阳明厥则喘而惋，惋则恶人。
邪热入阳明中土，土畏木，故闻木音而惊也；热甚故恶火，仲景所云不恶寒反恶热也；邪结而气厥逆，
则喘而惋，惋者懊 ，故恶人也。
帝曰∶或喘而死者，或喘而生者，何也？岐伯曰∶厥逆连脏则死，连经则生。
厥逆者，邪结胃腑，阳不达于四肢而厥冷，所谓阳极似阴之假寒证也。邪内入则连脏而阳陷，故死；邪外
出则连经而阳伸，故生。
帝曰∶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？岐伯曰∶四肢者，诸阳之本也。阳盛则四肢实，实则能登高也。帝曰∶其弃衣而走者，何也？岐伯曰∶
热盛于身，故弃衣欲走也。帝曰∶其妄言骂詈，不避亲疏而歌者，何也？岐伯曰∶阳盛则使人妄言骂詈，不
避亲疏，而不欲食，不欲食，故妄走也。
四肢皆禀气于胃，胃为脏腑之海，而阳明行气于三阳，故四肢为诸阳之本。邪盛于胃，则气实于四肢，故
能登高也；身热盛，故弃衣；邪乱神明，怒气冲动，故妄言骂詈；胃中邪实，故不欲食；四肢多力，故妄走也。
黄帝问道：足阳明经脉发生病变时，患者厌恶人和火光，听到木器的声音就会惊恐不安，但听到钟鼓的声音却不被惊动。为什么听到木器的声音会惊恐呢？岐伯回答说：足阳明经是胃的经脉，胃在五行中属土，所以听到木器的声音而惊恐，是因为土畏惧木（木克土）的缘故。黄帝问：他为什么厌恶火呢？岐伯回答说：阳明经主司肌肉，其经脉中气血旺盛，邪气侵入后会产生热象，热势严重时就厌恶火。黄帝问：他为什么厌恶人呢？岐伯回答说：阳明经气逆乱会导致喘息和心中烦闷懊恼，心中烦闷懊恼就厌恶人。
邪热侵入阳明中土，土畏惧木，所以听到木音而惊恐；热势严重所以厌恶火，这就是张仲景所说的“不恶寒反恶热”；邪气结聚导致气机逆乱，就会出现喘息和烦闷，烦闷就是心中的懊恼感，所以厌恶人。
黄帝问：有的患者因喘息而死，有的因喘息而活，这是为什么呢？岐伯回答说：如果厥逆之气连及内脏则死，仅连及经络则生。
所谓厥逆，是指邪气结聚于胃腑，阳气不能通达四肢而导致四肢厥冷，这被称为“阳极似阴”的假寒证。邪气向内深入则连及内脏，导致阳气下陷，所以死亡；邪气向外透发则连及经络，导致阳气伸展，所以生存。
黄帝问：病情严重时，患者脱掉衣服奔跑，登上高处唱歌，或者几天不吃饭，翻越墙垣、爬上屋顶，所去的地方都是平时做不到的，病反而能这样做，是什么原因呢？岐伯回答说：四肢是诸阳经的根本。阳气亢盛则四肢充实有力，充实有力就能登高。黄帝问：他为什么要脱掉衣服奔跑呢？岐伯回答说：因为体内热势炽盛，所以脱掉衣服想要奔跑。黄帝问：他胡言乱语、骂人，不分亲疏且唱歌，是什么原因呢？岐伯回答说：阳气亢盛会使人胡言乱语、骂人，不分亲疏，并且不想进食，不想进食，所以胡乱奔走。
四肢都禀受胃气，胃是脏腑之海，而阳明经将气行于三阳经，所以四肢是诸阳经的根本。邪气盛于胃，则气实于四肢，所以能登高；身体热势盛，所以脱掉衣服；邪气扰乱神明，怒气冲动，所以胡言乱语、骂人；胃中有邪气实结，所以不想进食；四肢多力，所以胡乱奔走。
The Yellow Emperor asked: When the Foot-Yangming meridian is diseased, the patient dislikes people and fire, and is startled upon hearing the sound of wood, yet is not moved by the sound of bells and drums. Why does the sound of wood cause alarm? Qibo replied: The Yangming is the stomach meridian; the stomach belongs to Earth in the Five Elements. Therefore, the alarm caused by the sound of wood occurs because Earth fears Wood (Wood overcomes Earth). The Yellow Emperor asked: Why does he dislike fire? Qibo replied: Yangming governs the flesh, and its meridian has abundant blood and qi. When pathogenic factors invade, heat is generated; when the heat is severe, the patient dislikes fire. The Yellow Emperor asked: Why does he dislike people? Qibo replied: Reversal of Qi in Yangming leads to panting and mental depression/distress; due to this distress, the patient dislikes people.
When pathogenic heat enters the central Earth of Yangming, Earth fears Wood, hence the alarm at the sound of wood; due to severe heat, there is a dislike for fire, which corresponds to Zhang Zhongjing’s statement of "no aversion to cold but aversion to heat"; when pathogenic factors bind and Qi reverses, panting and distress occur; distress refers to inner restlessness (Ao Nao), hence the dislike for people.
The Yellow Emperor asked: Some patients die from panting, while others survive; why is this? Qibo replied: If reversal extends to the Zang organs, death ensues; if it extends only to the meridians, survival occurs.
Reversal (Jue Ni) refers to pathogenic factors binding in the Stomach Fu organ, preventing Yang Qi from reaching the four limbs, resulting in cold extremities. This is known as the false cold syndrome of "extreme Yang resembling Yin." If pathogens enter inward, they connect with the Zang organs, causing Yang Qi to sink, leading to death; if pathogens move outward, they connect with the meridians, allowing Yang Qi to extend, leading to survival.
The Yellow Emperor asked: In severe cases, patients discard their clothes and run, climb high places and sing, or go without food for several days, climbing walls and roofs—places they could never reach normally. Why can they do things contrary to their usual abilities? Qibo replied: The four limbs are the root of all Yang meridians. When Yang is excessive, the four limbs become solid and strong, enabling one to climb high. The Yellow Emperor asked: Why do they discard clothes and run? Qibo replied: Because heat is excessive in the body, they discard clothes and wish to run. The Yellow Emperor asked: Why do they speak nonsensically, curse, disregard kinship and distance, and sing? Qibo replied: Excessive Yang causes nonsensical speech, cursing, and disregard for relationships; combined with loss of appetite, this leads to aimless running.
The four limbs receive Qi from the Stomach; the Stomach is the sea of the Zang and Fu organs, and the Yangming meridian circulates Qi through the three Yang meridians; thus, the four limbs are the root of all Yang. When pathogens are excessive in the Stomach, Qi becomes solid in the four limbs, enabling climbing; when body heat is excessive, clothes are discarded; when pathogens disturb the Shen (Spirit), anger and impulse arise, causing nonsensical speech and cursing; when the Stomach contains pathogenic excess, appetite is lost; when the four limbs have strength, aimless running occurs.
