黄帝问曰∶邪气之中人奈何？高下有度乎？岐伯对曰∶身半以上者，邪中之；身半以下者
，湿中之；中于阴则留腑，中于阳则留脏。曰∶阴之与阳，异名同类，上下相会，经络之相
贯也，如环之无端。夫邪之中人也，或中于阴，或中于阳，上下左右，无有恒常。曰∶诸阳
之会，皆在于面，人之方乘虚时及新用力，若热饮汗出，腠理开而中于邪，中于首则下阳
明，中于面则下太阳，中于颊则下少阳，中于膺背两胁，亦中其经。中于阴者，常从臂
始。夫臂与 ，其阴皮薄，其肉淖泽，故俱受于风，独伤于其阴也。曰∶此故伤其脏
乎？曰∶身之中于风也，不必动脏。故邪入于阴经，其脏气实，邪气入而不容，故还之于
腑。是故阳中则留于经，阴中则留于腑。曰∶邪之中脏者奈何？曰∶恐惧忧愁则伤心。形寒
饮冷则伤肺，以其两寒相感，中外皆伤，故气逆而上行。有所堕坠，恶血留内，有所大怒，
气上而不能下，积于胁下则伤肝。有所击仆，若醉以入房，汗出当风则伤脾。有所用力举重
，若入房过度，汗出浴水则伤肾。
曰∶五脏之中风奈何？曰∶阴阳俱相感，邪乃得往。十二经脉，三百六十五络，其血气
皆上于面而走空窍。其精阳之气，上走于目而为睛，其别气走于耳而为听，其宗气上出于鼻
而为臭，其浊气下出于胃而走唇舌而为味。其气之津液皆上熏于面，而皮又浓，其肉坚，故
大热甚，寒不能胜之也。虚邪之中身也，洒淅动其形。正邪之中人也微，先见于色，不知于身
，若存若亡，有形无形，莫知其情。夫色脉与尺之皮肤相应，如桴鼓影响之相应，不得相失，
此亦本末根叶之出候也，根死则叶枯矣。故色青者其脉弦，色赤者其脉钩，色黄者其
脉代，色白者其脉毛，色黑者其脉石。见其色而不得其脉，反得相胜之脉则死矣；得
相生之脉则病已矣。曰∶五脏之所生变化之病形何如？曰∶先定其五色五脉之应，其病乃可
别也。曰∶色脉已定，别之奈何？曰∶调其脉之缓急大小滑涩，而病形定矣。曰∶调之何如？
曰∶脉急者，尺之皮肤亦急；脉缓者，尺之皮肤亦缓；脉小者，尺之皮肤亦减而少气；脉大
者，尺之皮肤亦大；脉沉者，尺之皮肤亦沉；脉滑者，尺之皮肤亦滑；脉涩者，尺之皮肤亦
涩。凡此变者，有微有甚。故善调尺者，不待于寸；善调脉者，不待于色。能参合而行之者
，可以为上工，十全其九；行二者为中工，十全其七；行一者为下工，十全其六。尺肤温
（一作滑）以淖泽者，风也。尺肉弱者，解 也。安卧脱肉者，寒热也（一本下作不治）。
尺肤涩者，风痹也。尺肤粗如枯鱼鳞者，水 饮也。尺肤寒甚脉急（一作小）者，泄少气

一作炬然），先热后寒者，寒热也。尺肤先寒，久持之而热者，亦寒热也。尺肤炬然热，人
迎大者，当夺血也。尺坚大脉小甚则少气， 有加者，立死（《脉经》云∶尺紧于
人迎者少气）。肘所独热者，腰以上热。肘后独热者，肩背热。肘前独热者，膺前热。肘后

掌中热者，腹中热也。掌中寒者，腹中寒也。鱼际白肉有青血脉者，胃中有寒也。
曰∶人有尺肤缓甚（一云尺脉数甚）筋急而见，此为何病？曰∶此所谓狐（狐，《素问》作
疹）筋。狐筋者，是人腹必急，白色黑色见，则病甚。
黄帝问道：邪气侵袭人体是怎样的情况？有上下高低的规律吗？岐伯回答说：身体上半部的，多被风邪所中；身体下半部的，多被湿邪所中；邪气侵入阴分则留滞于腑，侵入阳分则留滞于脏。黄帝说：阴与阳，名称不同但同类，上下相互交会，经络相互贯通，像圆环一样没有尽头。邪气侵袭人体，有的侵入阴分，有的侵入阳分，上下左右，没有固定的常规。黄帝说：诸阳经的交会点都在面部，当人处于正气虚弱之时，或刚用力过度，以及热饮后出汗，腠理（皮肤毛孔）张开时容易受邪气侵袭。邪气中于头部，则向下传入足阳明胃经；中于面部，则向下传入足太阳膀胱经；中于面颊，则向下传入足少阳胆经；中于胸膺、背部及两胁，也传入相应的经脉。邪气侵入阴分的，通常从手臂开始。因为手臂和腿胫内侧，皮肤薄嫩，肌肉柔润，所以容易共同受到风邪侵袭，唯独损伤其阴分。黄帝问：这是否一定会伤及内脏呢？岐伯说：身体遭受风邪侵袭，不一定都会动及内脏。所以邪气进入阴经，如果脏气充实，邪气进入而无处容身，就会返还到腑。因此，阳经受邪则留滞在经脉，阴经受邪则留滞在腑。黄帝问：邪气中于脏的情况是怎样的呢？岐伯说：恐惧忧愁会伤心；形体受寒、饮食生冷会伤肺，因为内外两种寒气相感，导致内外都受伤，所以气逆而上行。如果有跌坠损伤，恶血留积在体内，或者大怒，气上冲而不能下行，积聚在胁下则会伤肝。如果有击打仆倒，或者醉酒后行房事，汗出当风则会伤脾。如果用力举重，或者房事过度，汗出后立即洗冷水浴则会伤肾。
黄帝问：五脏感受风邪是怎样的情况呢？岐伯说：阴阳之气相互感应，邪气才能传往。十二经脉和三百六十五络穴，它们的血气都上行于面部并通达各个孔窍。其中清阳之气，上行至目而成为视觉；别行之气上行至耳而成为听觉；宗气上行出于鼻而成为嗅觉；浊气下行出于胃而通达唇舌以辨别味道。这些气的津液都向上熏蒸于面部，而且面部皮肤厚实，肌肉坚实，所以即使大热甚盛，寒气也不能胜过它。虚邪侵袭身体时，会使人体感到洒淅恶寒而动摇身形。正邪侵袭人体很轻微，先表现在面色上，身体感觉不到，似有似无，有形无形，没有人能知道它的实情。面色、脉象与尺部皮肤的反应是相应的，就像鼓槌与鼓声、影子与物体那样相应，不能失去联系，这也是根本与枝叶的外在征候，根死了枝叶就会枯死。所以面色青的，脉象弦；面色赤的，脉象钩；面色黄的，脉象代；面色白的，脉象毛；面色黑的，脉象石。看到面色却诊不到相应的脉象，反而得到相克制的脉象就会死亡；得到相生之脉则病将痊愈。黄帝问：五脏所产生的变化病症表现如何呢？岐伯说：先确定五色与五脉的对应关系，病症才可以区分。黄帝问：面色和脉象已经确定，如何进一步辨别呢？岐伯说：通过调察脉象的缓急、大小、滑涩，病症的表现就可以确定了。黄帝问：如何调察呢？岐伯说：脉象紧急的，尺部皮肤也紧张；脉象缓和的，尺部皮肤也松弛；脉象细小的，尺部皮肤也减损且少气；脉象大的，尺部皮肤也宽大；脉象沉的，尺部皮肤也深沉；脉象滑利的，尺部皮肤也滑利；脉象涩滞的，尺部皮肤也涩滞。所有这些变化，有轻微也有严重。所以善于调察尺肤的人，不需要等待寸口脉；善于调察脉象的人，不需要等待面色。能将三者结合参验而行医的，可以称为上工，治愈率可达十分之九；只实行两项的为中工，治愈率可达十分之七；只实行一项的为下工，治愈率可达十分之六。尺部皮肤温热且滑润的，是风病。尺部肌肉瘦弱的，是懈惰病。安静卧床且肌肉脱落的，是寒热病（另一版本作不治）。尺部皮肤涩滞的，是风痹病。尺部皮肤粗糙如枯鱼鳞状的，是水饮病。尺部皮肤很冷且脉象紧急（一作细小）的，是泄泻且少气。尺部皮肤很热且脉象盛大躁动的，是温病。脉象盛大而滑利的，即将出汗（一作病将发作）。尺部皮肤烧灼般烫手（一作如火炬燃烧），先热后冷的，是寒热病。尺部皮肤先冷，久按之后变热的，也是寒热病。尺部皮肤灼热，人迎脉大的，应当是失血证。尺部皮肤坚硬而脉象细小严重的则少气，如果出现某种特定脉象（原文缺字，据《脉经》推测为紧脉等凶兆），立即死亡（《脉经》说：尺脉紧于人迎脉的是少气）。肘部单独发热的，是腰部以上发热。肘后部单独发热的，是肩背部发热。肘前部单独发热的，是胸膺前部发热。肘后侧下方三四寸处发热的，是肠中有虫。手部单独发热的，是腰部以上（一作以下）发热。臂中部单独发热的，是腰腹部发热。手掌心发热的，是腹中发热。手掌心发冷的，是腹中寒冷。大鱼际白肉处有青色血脉的，是胃中有寒。
黄帝问：有人尺部皮肤松弛得很厉害（一说尺脉数动得很厉害），筋脉拘急而显现，这是什么病？岐伯说：这就是所说的狐疝筋病。狐疝筋病，这个人的腹部必然拘急，如果面色出现白色或黑色，则病情加重。
Huangdi asked: How do pathogenic factors invade the human body? Is there a regularity in their high and low positions? Qibo replied: For the upper half of the body, they are invaded by wind pathogens; for the lower half of the body, they are invaded by dampness pathogens. If invading the Yin aspect, they remain in the Fu organs (hollow organs); if invading the Yang aspect, they remain in the Zang organs (solid organs). Huangdi said: Yin and Yang have different names but are of the same category; they meet above and below, and the meridians interconnect like a circle without beginning or end. When pathogens invade the body, they may invade the Yin or the Yang, with no fixed pattern in the upper, lower, left, or right. Huangdi said: The convergence points of all Yang meridians are located on the face. When a person is in a state of deficiency, or has just exerted themselves physically, or after drinking hot liquids and sweating, when the Cou Li (skin pores) are open, they are susceptible to pathogens. If the pathogen strikes the head, it descends into the Foot-Yangming Stomach Meridian; if it strikes the face, it descends into the Foot-Taiyang Bladder Meridian; if it strikes the cheek, it descends into the Foot-Shaoyang Gallbladder Meridian; if it strikes the chest, back, or flanks, it also enters the corresponding meridians. Pathogens invading the Yin aspect usually start from the arms. This is because the skin on the inner sides of the arms and legs is thin, and the muscles are soft and moist, so they are jointly susceptible to wind pathogens and uniquely injured in their Yin aspects. Huangdi asked: Does this necessarily injure the Zang organs? Qibo said: Invasion by wind pathogens does not necessarily disturb the Zang organs. Therefore, when pathogens enter the Yin meridians, if the Qi of the Zang organs is substantial, the pathogens cannot reside there and thus return to the Fu organs. Hence, invasion of the Yang aspect remains in the meridians, while invasion of the Yin aspect remains in the Fu organs. Huangdi asked: What is the situation when pathogens strike the Zang organs? Qibo said: Fear and worry injure the Heart; cold exposure of the body and consumption of cold drinks injure the Lungs, because the two types of cold interact, injuring both inside and outside, causing Qi to rebel and move upward. Falls or injuries causing blood stasis to remain internally, or extreme anger causing Qi to rush upward and fail to descend, accumulating under the flanks, will injure the Liver. Blows or falls, or sexual intercourse while drunk, sweating and then exposing oneself to wind, will injure the Spleen. Straining to lift heavy objects, or excessive sexual intercourse followed by bathing in cold water while sweating, will injure the Kidneys.
Huangdi asked: How do the Five Zang organs contract wind pathogens? Qibo said: When Yin and Yang Qi mutually resonate, pathogens can travel. The Twelve Primary Meridians and the 365 Luo Connecting Points, their Blood and Qi all ascend to the face and flow through the sensory orifices. The clear Yang Qi ascends to the eyes to form vision; branch Qi ascends to the ears to form hearing; the Zong Qi (Pectoral Qi) ascends out of the nose to form smell; the turbid Qi descends out of the Stomach to reach the lips and tongue to form taste. The fluids and essence of these Qi all steam upwards onto the face. Since the facial skin is thick and the muscles firm, even intense heat cannot be overcome by cold. When Xu Xie (deficiency pathogens) invade the body, they cause shivering and bodily trembling. Zheng Xie (regular pathogens) invading the body are subtle; they first manifest in the complexion, are not felt by the body, seem to exist and yet not, having form and yet formless, and no one knows their true nature. The complexion, pulse, and skin of the Cubital Region (Chi area) correspond to each other, like the drumstick and drum sound, or shadow and object, and must not lose this correspondence. This is also an external manifestation of the root and branches; if the root dies, the branches wither. Thus, a green complexion corresponds to a Wiry (Xian) pulse; a red complexion corresponds to a Hook (Gou) pulse; a yellow complexion corresponds to a Intermitting (Dai) pulse; a white complexion corresponds to a Hairy (Mao) pulse; a black complexion corresponds to a Stone (Shi) pulse. If the complexion is seen but the corresponding pulse is not found, and instead a controlling (overcoming) pulse is obtained, death will occur; if a generating pulse is obtained, the disease will heal. Huangdi asked: What are the manifestations of diseases generated by changes in the Five Zang organs? Qibo said: First determine the correspondence between the Five Complexions and Five Pulses, then the diseases can be distinguished. Huangdi asked: Once the complexion and pulse are determined, how else can they be differentiated? Qibo said: By examining the pulse for slackness/tightness, large/small, slippery/rough, the manifestations of the disease can be determined. Huangdi asked: How to examine them? Qibo said: If the pulse is tight, the skin of the Cubital Region is also tight; if the pulse is slack, the skin of the Cubital Region is also slack; if the pulse is small, the skin of the Cubital Region is diminished and indicates deficient Qi; if the pulse is large, the skin of the Cubital Region is also large; if the pulse is deep, the skin of the Cubital Region is also deep; if the pulse is slippery, the skin of the Cubital Region is also slippery; if the pulse is rough, the skin of the Cubital Region is also rough. All these variations have degrees of mildness and severity. Therefore, one skilled in examining the Cubital Region need not wait for the Cun Kou (radial) pulse; one skilled in examining the pulse need not wait for the complexion. One who can integrate all three methods can be called a Superior Physician, achieving nine cures out of ten; one who uses two methods is a Medium Physician, achieving seven cures out of ten; one who uses only one method is an Inferior Physician, achieving six cures out of ten. Warm and smooth/moist skin of the Cubital Region indicates Wind Disease. Weak flesh in the Cubital Region indicates Flaccidity Disease. Quiet lying down with muscle wasting indicates Cold-Heat Disease (another version says Incurable). Rough skin of the Cubital Region indicates Wind Bi Syndrome. Skin of the Cubital Region coarse like dried fish scales indicates Water Retention Disease. Very cold skin of the Cubital Region with a tight (or small) pulse indicates Diarrhea and Deficient Qi. Very hot skin of the Cubital Region with a full and restless pulse indicates Warm Disease. A full and slippery pulse indicates impending sweating (or disease onset). Burning-hot skin of the Cubital Region (like a torch), starting hot then becoming cold, indicates Cold-Heat Disease. Skin of the Cubital Region initially cold, becoming hot after prolonged pressure, also indicates Cold-Heat Disease. Burning-hot skin of the Cubital Region with a large Ren Ying (Carotid) pulse indicates Blood Loss. Hard skin of the Cubital Region with a very small pulse indicates Deficient Qi; if accompanied by specific ominous pulses, death occurs immediately (The Mai Jing states: A Chi pulse tighter than the Ren Ying pulse indicates Deficient Qi). Heat isolated at the elbow indicates heat in the upper waist. Heat isolated at the posterior elbow indicates heat in the shoulder and back. Heat isolated at the anterior elbow indicates heat in the anterior chest. Heat in the lower third of the posterior elbow indicates intestinal worms. Heat isolated at the hand indicates heat in the upper waist (or lower waist). Heat isolated in the middle of the arm indicates heat in the waist and abdomen. Heat in the palm indicates heat in the abdomen. Cold in the palm indicates cold in the abdomen. Blue blood vessels visible on the white flesh of the Thenar Eminence indicate Cold in the Stomach.
Huangdi asked: There is a case where the Cubital Region skin is extremely lax (or the Chi pulse is extremely rapid), and tendons are tense and visible. What disease is this? Qibo said: This is called Hu Jin (Fox Tendon Disease/Hernia). In Hu Jin Disease, the abdomen is necessarily tense; if the complexion shows white or black, the condition worsens.
