雷公问于黄帝曰。禁脉之言。（经有禁服篇所叙皆脉事疑彼处服字误有谓脉字误者恐未必然）凡刺之理。经脉为始。
营其所行。制其度量。内次五脏。外别六腑。愿尽闻其道。黄帝曰。人始生。先成精。精成而脑髓生。骨为干。脉为营。
筋为刚。肉为墙。皮肤坚而毛发长。谷入于胃。脉道以通。血气乃行。雷公曰。愿卒闻经脉之始生。黄帝曰。经脉者。

雷公向黄帝问道：关于禁脉的论述，（《内经》中有《禁服》篇，其中叙述的都是脉学内容，怀疑那里的“服”字是误写，也有人说是“脉”字误写，我认为未必如此。）凡针刺的道理，以经脉为起始。
要掌握营气运行的路径，确定其度量标准，向内关联五脏，向外区分六腑。我希望详尽地听闻其中的道理。
黄帝说：人最初生成时，先形成精。精形成后脑髓产生。骨作为支撑，脉作为营卫运行的通道，筋作为刚强部分，肉作为围墙。皮肤坚固而毛发生长。谷物进入胃中，脉道通畅，血气便开始运行。
雷公说：我希望彻底了解经脉是如何生成的。
黄帝说：经脉，是用来判断生死、处理各种疾病、调节虚实的关键，不可不通晓。

手太阴肺气绝，则皮毛干枯。太阴经是运行气并温煦皮毛的。所以气不荣养，则皮毛干枯。皮毛干枯则津液离开皮节，津液离开皮节则指甲枯槁、毛发折断。毛发折断，说明毛先死。丙日加重，丁日死亡，这是火胜金。
手少阴心气绝，则脉不通。脉不通则血不流。血不流则毛发色泽不润。所以面色黑如漆柴，说明血先死。壬日加重，癸日死亡，这是水胜火。
足太阴脾气绝，则脉不荣养肌肉。唇舌是肌肉的根本。脉不荣养则肌肉软弱。肌肉软弱则舌萎、人中满。人中满则唇反。唇反说明肉先死。甲日加重，乙日死亡，这是木胜土。
足少阴肾气绝，则骨枯。少阴是冬脉，潜行而濡养骨髓。所以骨不濡养则肉不能附着。骨肉不相亲，则肉软退缩。肉软退缩故牙齿显得长且垢秽，头发无光泽。头发无光泽说明骨先死。戊日加重，己日死亡，这是土胜水。
足厥阴肝气绝则筋绝。厥阴是肝脉。肝是筋的汇聚处。筋聚于阴器而脉络于舌本。所以脉不荣养则筋急。筋急则牵引舌和睾丸。所以唇青、舌卷、睾丸收缩，说明筋先死。庚日加重，辛日死亡，这是金胜木。
五脏阴气都绝，则目系转动。转动则目眩。目眩说明神志先死。神志先死则一天半后死亡。
六腑阳气都绝，则阴与阳分离。分离则腠理开泄，绝汗乃出。所以早上占测晚上死，晚上占测早上死。
十二经脉，潜伏运行于分肉之间，深而不见。常见的是足太阴脾经，因为经过内踝之上，无处隐藏，所以可见。（“内”字原作“外”，有误。阴脉不行于外踝，且内踝上有大青脉直上至膝才逐渐隐没，应当就是此脉。）诸脉浮而常见的，都是络脉。
六经的络脉：手阳明、手少阳的大络，起于五指间，上合于肘中。饮酒的人，卫气先行于皮肤，先充塞络脉，络脉先盛。所以卫气已平复，营气乃充满，而经脉大盛。
脉突然动的，都是邪气停留。停留于根本末端，不动则热，不坚则陷且空，不与众脉同，因此知道是哪条脉在动。
雷公问：如何知道经脉与络脉的区别？
黄帝说：经脉通常看不见。其虚实，通过气口（寸口）得知。脉可见的，都是络脉。
雷公说：学生无法明白为什么是这样。
黄帝说：诸络脉都不能经过大关节之间，必行于绝道（特殊通道），而出入复合于皮中，其交会点都见于外面。所以刺络脉者，必刺其结聚之上。血多者，即使无结聚，也必须急取之，以泻其邪而出其血。若留之不去，会发展为痹证。
凡是诊察络脉，脉色青则寒且痛，赤则有热。胃中寒，手鱼部的络脉多青。胃中有热，鱼际络脉赤。其突然变黑的，是久留的痹证。其有赤有黑有青的，是寒热气夹杂。其青而短的，是少气。
凡是刺寒热证，都要多刺血络，必须隔日取一次，血尽才停止，然后调其虚实。其脉小而短、少气严重的，泻之则会胸闷。闷甚则仆倒，不能说话。胸闷则急令其坐下。
手太阴肺经的别络，名叫列缺。起于腕上分间，并手太阴经直入掌中，散入于鱼际。其病，实证则手锐掌热，虚则欠伸、小便遗数。取之去腕半寸，别走阳明经。
手少阴心经的别络，名叫通里。去腕一寸半，别而上行，循经入于心中，系舌本，属目系。其病，实证则支膈，虚则不能言。取之掌后一寸，别走太阳经。
手厥阴心包经的别络，名叫内关。去腕二寸，出于两筋之间，循经以上，系于心包络、心系。实证则心痛，虚则头强。取之两筋
Lei Gong asked Huang Di: Regarding the discourse on restricted pulses (Jin Mai), (In the *Nei Jing*, there is a chapter titled "Jin Fu" which narrates matters concerning pulse diagnosis. It is suspected that the character "Fu" in that place might be an error, and some suggest it should be "Mai" [pulse], but I believe this is not necessarily so.) In all acupuncture principles, the meridians are the starting point.
One must master the pathways of Ying Qi (Nutritive Qi), determine their measurements, internally connect with the Five Zang Organs, and externally distinguish the Six Fu Organs. I wish to hear the complete explanation of these methods.
Huang Di said: When humans first originate, Essence (Jing) forms first. Once Essence is formed, brain and marrow are generated. Bones serve as the framework, meridians act as the channels for Ying Qi circulation, tendons provide strength, flesh acts as a protective wall. The skin is firm and hair grows long. When grain enters the stomach, the meridian pathways become unobstructed, and Blood and Qi begin to flow.
Lei Gong said: I wish to fully understand how the meridians originate.
Huang Di said: The meridians are used to decide life and death, manage various diseases, and regulate deficiency and excess; they cannot be left unexamined.
The Hand-Taiyin Lung Meridian originates from the Middle Jiao (Middle Burner), descends to connect with the Large Intestine, returns along the stomach opening, passes through the diaphragm, and belongs to the Lung. From the lung system (trachea and throat), it emerges horizontally below the armpit, descends along the anterior aspect of the upper arm, running anterior to the Hand-Shaoyin Heart Meridian and Hand-Jueyin Pericardium Meridian, descends into the elbow midpoint, follows the medial aspect of the forearm along the lower border of the radius, enters the Cun Kou (inch position/radial artery pulse point), ascends to the Thenar eminence (Yu Ji), follows the border of the thenar eminence, and exits at the tip of the thumb. Its branch arises from behind the wrist, goes directly to the medial side of the index finger, and exits at its tip. When this meridian undergoes pathological changes, disease occurs: lung distension, fullness, panting, coughing, upward rushing of Qi, pain in the supraclavicular fossa (Que Pen), and in severe cases, crossing both hands over the chest while experiencing visual disturbance (Mao). This is called Arm Jue (Arm Reversal). This meridian governs diseases produced by the Lung, including coughing with upward rushing Qi, panting with sound, vexation, chest fullness, pain and coldness along the anterior-medial border of the arm, and heat in the palm. If Qi is excessive and surplus, there is shoulder and back pain, aversion to wind and cold, sweating, wind-stroke, frequent urination with small volume. If Qi is deficient, there is shoulder and back pain with cold sensation, shortness of breath insufficient for respiration, and change in urine color. For these diseases, excess is treated by draining, deficiency by tonifying, heat by rapid needling, cold by retaining the needle, sinking Qi by moxibustion, and neither excess nor deficiency by treating the meridian itself. Excess is indicated when the Cun Kou pulse is three times larger than the Ren Ying pulse; deficiency is indicated when the Cun Kou pulse is smaller than the Ren Ying pulse.
The Hand-Yangming Large Intestine Meridian originates at the tip of the index finger, follows the radial border of the finger, emerges between the two bones at He Gu, enters between the two tendons, follows the radial border of the forearm, enters the lateral aspect of the elbow, ascends along the anterior-lateral border of the upper arm, reaches the shoulder, emerges anterior to the acromion, ascends to emerge at the confluence of vertebral bones (Da Zhui), descends into the Que Pen (supraclavicular fossa), connects with the Lung, passes through the diaphragm, and belongs to the Large Intestine. Its branch arises from the Que Pen, ascends the neck, pierces the cheek, enters the lower teeth, returns out, crosses the mouth, intersects at the Ren Zhong, crossing from left to right and right to left, ascending to flank the nostrils. When this meridian undergoes pathological changes, disease occurs: toothache, neck swelling. This meridian governs diseases produced by Fluids (Jin Ye), including yellow eyes, dry mouth, rhinorrhea or epistaxis, throat obstruction, pain in the anterior shoulder, and pain/immobility of the index finger. If Qi is surplus, heat and swelling occur along the meridian's pathway; if deficient, there is cold shivering that does not resolve. For these diseases, excess is treated by draining, deficiency by tonifying, heat by rapid needling, cold by retaining the needle, sinking Qi by moxibustion, and neither excess nor deficiency by treating the meridian itself. Excess is indicated when the Ren Ying pulse is three times larger than the Cun Kou pulse; deficiency is indicated when the Ren Ying pulse is smaller than the Cun Kou pulse.

Another branch diverges three cun below the knee, entering the lateral space of the middle toe. Another branch diverges from the dorsum of the foot, enters the space between the big toe, and exits at its tip. When this meridian undergoes pathological changes, disease occurs: chills, frequent groaning, yawning, dark complexion. Upon onset, there is aversion to people and fire, startle upon hearing wood sounds, palpitations, desire to close doors and windows and stay alone, and in severe cases, climbing high to sing, discarding clothes and running, rumbling abdominal distension. This is called Gan Jue. This meridian governs diseases produced by Blood, including mania, malaria, warm pathogen-induced sweating, rhinorrhea/epistaxis, facial paralysis, lip herpes, neck swelling, throat obstruction, massive abdominal edema, knee/patellar swelling, pain along the chest, breast, Qi Chuan, thigh, Fu Tu, lateral calf, and dorsum of the foot, immobility of the middle toe. If Qi is surplus, heat pervades the anterior body; if Stomach Qi is surplus, there is rapid digestion with hunger, yellow urine. If Qi is deficient, cold shivers pervade the anterior body; cold in the Stomach causes distension. For these diseases, excess is treated by draining, deficiency by tonifying, heat by rapid needling, cold by retaining the needle, sinking Qi by moxibustion, and neither excess nor deficiency by treating the meridian itself. Excess is indicated when the Ren Ying pulse is three times larger than the Cun Kou pulse; deficiency is indicated when the Ren Ying pulse is smaller than the Cun Kou pulse.

Its branch arises from the eye system, descends into the cheek/lips, circles the inside of the lips. Another branch diverges from the Liver, penetrates the diaphragm, and pours into the Lung. When this meridian undergoes pathological changes, disease occurs: low back pain preventing bending/straightening, hernia in men, lower abdominal swelling in women, severe case with dry throat, dusty complexion, loss of color. This meridian governs diseases produced by the Liver, including chest fullness, reverse vomiting, undigested food diarrhea, fox hernia, enuresis, stranguria. For these diseases, excess is treated by draining, deficiency by tonifying, heat by rapid needling, cold by retaining the needle, sinking Qi by moxibustion, and neither excess nor deficiency by treating the meridian itself. Excess is indicated when the Cun Kou pulse is one time larger than the Ren Ying pulse; deficiency is indicated when the Cun Kou pulse is smaller than the Ren Ying pulse.
When the Qi of the Hand-Taiyin Meridian terminates, the skin and hair become dry. The Taiyin Meridian circulates Qi and warms the skin and hair. Thus, if Qi does not nourish, the skin and hair become dry. If the skin and hair become dry, fluids leave the skin joints. If fluids leave the skin joints, nails wither and hair breaks. If hair breaks, hair dies first. Bing day brings worsening, Ding day brings death; Fire conquers Metal.
When the Qi of the Hand-Shaoyin Meridian terminates, the vessels become obstructed. If vessels are obstructed, blood does not flow. If blood does not flow, hair loses luster. Thus, the face becomes black as lacquered charcoal; blood dies first. Ren day brings worsening, Gui day brings death; Water conquers Fire.
When the Qi of the Foot-Taiyin Meridian terminates, the vessels do not nourish the muscles. The lips and tongue are the root of the muscles. If vessels do not nourish, muscles become soft. If muscles become soft, the tongue atrophies and the philtrum fills. If the philtrum fills, the lips invert. If lips invert, flesh dies first. Jia day brings worsening, Yi day brings death; Wood conquers Earth.
When the Qi of the Foot-Shaoyin Meridian terminates, the bones become withered. Shaoyin is the Winter Pulse, hiding within to moisten the bone marrow. Thus, if bones are not moistened, flesh cannot adhere. If flesh and bone are not intimate, flesh becomes soft and recedes. If flesh recedes, teeth appear long and dirty, and hair lacks luster. If hair lacks luster, bone dies first. Wu day brings worsening, Ji day brings death; Earth conquers Water.
When the Qi of the Foot-Jueyin Meridian terminates, the tendons cease. Jueyin is the Liver Meridian. The Liver is the convergence of tendons. Tendons gather at the genitalia and connect to the root of the tongue. Thus, if vessels do not nourish, tendons become tense. If tendons become tense, they pull the tongue and testicles. Thus, blue lips, curled tongue, and retracted testicles indicate tendon death first. Geng day brings worsening, Xin day brings death; Metal conquers Wood.
When the Yin Qi of the Five Zang Organs all terminates, the eye system rotates. Rotation causes dizziness. Dizziness indicates Spirit (Zhi) dies first. If Spirit dies first, death occurs in one and a half days.
When the Yang Qi of the Six Fu Organs all terminates, Yin and Yang separate. Separation causes pores to open, and absolute sweat (Jue Han) emerges. Thus, morning prediction leads to evening death, evening prediction leads to morning death.
The twelve meridians run deep within the intermuscular spaces, invisible to the eye. What is commonly seen is the Foot-Taiyin Spleen Meridian, because it passes over the medial malleolus where there is no concealment. (The original text says "outer," which is an error. Yin meridians do not run on the lateral malleolus; there is a large blue vein on the medial malleolus going up to the knee before gradually disappearing, which is likely what is meant.) All floating and commonly visible vessels are Luo Vessels (Collaterals).
The great Luo Vessels of the six meridians: The Hand-Yangming and Hand-Shaoyang Luo Vessels arise between the five fingers and ascend to merge in the elbow. In drinkers, Wei Qi (Defensive Qi) moves first in the skin, filling the Luo Vessels first. Thus, when Wei Qi is balanced, Ying Qi fills, and the main meridians become highly prominent. Sudden movement of the pulse indicates Evil Qi residing there, staying at the root or extremity. If it does not move, there is heat; if not firm, it sinks and empties, differing from other pulses, allowing one to know which meridian is moving.
Lei Gong asked: How do we know the difference between Jing Meridians and Luo Vessels?
Huang Di said: Jing Meridians are usually invisible. Their deficiency or excess is known via the Qi Kou (Cun Kou). Visible vessels are all Luo Vessels.
Lei Gong said: I cannot understand why this is so.
Huang Di said: All Luo Vessels cannot pass through major joints; they must travel through unique paths, emerging and re-entering within the skin, with their intersections visible externally. Therefore, when needling Luo Vessels, one must needle above the nodules. If there is abundant blood, even without nodules, one must urgently drain it to expel the evil and release the blood. If retained, it develops into Bi Syndrome (Obstruction).
Generally, diagnosing Luo Vessels: Blue color indicates cold and pain; red indicates heat. Cold in the Stomach makes the Luo vessels on the大鱼际 (Thenar) mostly blue. Heat in the Stomach makes the Yu Ji vessels red. Sudden blackness indicates long-standing Bi. Mixed red, black, and blue indicates mixed cold and heat. Short and blue indicates Qi deficiency.
When needling cold-heat conditions, one should use many blood vessels, taking them every other day until the blood is exhausted, then regulating deficiency and excess. If the vessel is small and short, and Qi deficiency is severe, draining will cause chest stuffiness. Severe stuffiness leads to collapse and inability to speak. Stuffiness requires immediate sitting.
The Luo Vessel of the Hand-Taiyin Lung Meridian is named Lie Que. It arises from the interspace above the wrist, runs parallel to the Hand-Taiyin Meridian, enters the palm, and scatters in the thenar eminence. Diseases: Excess causes heat in the radial hand and palm; deficiency causes yawning/stretching and frequent/involuntary urination. Treat by taking the point half a cun from the wrist, which connects to the Yangming Meridian.
The Luo Vessel of the Hand-Shaoyin Heart Meridian is named Tong Li. It is one and a half cun from the wrist, diverges and ascends, follows the meridian, enters the Heart, ties to the root of the tongue, and belongs to the eye system. Diseases: Excess causes chest oppression; deficiency causes inability to speak. Treat by taking the point one cun behind the palm crease, which connects to the Taiyang Meridian.
The Luo Vessel of the Hand-Jueyin Pericardium Meridian is named Nei Guan. It is two cun from the wrist, emerges between the two tendons, follows the meridian upward, ties to the Pericardium and Heart System. Diseases: Excess causes heart pain; deficiency causes stiff neck. Treat by taking the point between the two tendons.
