黄帝问曰。余闻善言天者。必有验于人。善言古者。必有合于今。善言人者。必有厌于己。如此则道不惑而要数极。
所谓明也。（本经云。气伤痛。盖痛在有形之形身。而伤于无形之气分。是病皆生于寒热七情。而证见于脏腑经脉。举痛
而论。百病皆然。能会通此道。庶明而不惑。是以帝言知天道者。苟能验于人。知往古者。苟能合于今。善言人者。必
有足于己。如此则道不惑。而知要数之极。斯所谓之明道者也。）今余问于夫子。令言而可知。视而可见。扪而可得。冷
验于己。而发明解惑。可得而闻乎。（经云。知一为工。知二为上。知三为神。知斯三者。望见其色。按其脉。问其病也。
是以帝欲闻此三者之应验。而开发于未明。）岐伯再拜稽首对曰。何道之问也。（请示问端也。）帝曰。愿闻人之五脏卒痛。
何气使然。岐伯对曰。经脉流行不止。环周不休。寒气入经而稽迟。泣而不行。客于脉外则血少。客于脉中则气不通。
故卒然而痛。（泣音涩卒叶村入声经气流转。如环无端。寒气客之。则凝泣而不行矣。客于脉外则脉缩蜷而血少。客于脉
中则脉满而气不通。故卒然而痛也。张兆璜曰。气为阳。血为阴。气无形。血有形。气行脉外。血行脉中。客于脉外
则血少。客于脉中则气不通。正言其形气交感之要道。）帝曰。其痛或卒然而止者。或痛甚不休者。或痛甚不可按者。
或按之而痛止者。或按之无益者。或喘动应手者。或心与背相引而痛者。或胁肋与少腹相引而痛者。或腹痛引阴股者。
或痛宿昔而成积者。或卒然痛死不知人。有少间复生者。或痛而呕者。或腹痛而后泄者。或痛而闭不通者。凡此诸痛。
各不同形。别之奈何。（形、证也。言通证之各有不同。将何以别之。）岐伯曰。寒气客于脉外则脉寒。脉寒则缩蜷。缩
蜷则脉绌急。绌急则外引小络。故卒然而痛。得炅则痛立止。因重中于寒。则痛久矣。（绌音屈炅音炯重平声。绌、犹屈
也。寒则血凝泣。故脉缩蜷。缩蜷则绌急而外引小络。夫经脉为里。浮而外者为络。外内引急。故卒然而痛也。炅气、
太阳之气也。脉寒而得阳热之气。则缩绌即舒。故其痛立止。若复感于寒。则阳气受伤。故痛久而不止。莫子晋曰。太
阳、日中之火也。太阳主诸阳之气。阳热之甚者也。此受天之寒邪。得吾身之阳气以化热。故痛立止。）寒气客于经脉之
中。与炅气相搏则脉满。满则痛而不可按也。寒气稽留。炅气从上。则脉充大而气血乱。故痛甚不可按也。（荣血行于脉

而从上。血气不能相将而循行。则乱矣。）寒气客于肠胃之间。膜原之下。血不得散。小络急引。故痛。按之则血气散。
故按之痛止。（膜原者。连于肠胃之脂膜。亦气分之腠理。金匮要略云。腠者。是三焦通会元真之处。理者。皮肤脏腑之
纹理也。盖在外则为皮肤肌肉之腠理。在内则为横连脏腑之膜原。皆三焦通会元气之处。如寒气客于肠胃膜原之间。则
内引小络。故痛也。夫痛者阴也。气为阳。经络为阴。是以本篇论痛。皆邪伤于经脉。如邪客于脉外之气分。而迫于经
络为痛者。或得炅。或按之则痛止。盖寒邪得气而易散也。如邪入于经络而为痛者。甚则不可按。或虽按之无益。盖阴

在膜原之脉外。则内引小络而痛。盖膜原之间。有血络也。）寒气客于挟脊之脉则深。按之不能及。故按之无益也。（挟

于挟脊之冲脉则深。在于腹之冲脉。则浮于外而浅矣。）寒气客于冲脉。冲脉起于关元。随腹直上。寒气客则脉不通。脉
不通则气因之。故喘动应手矣。（此言冲脉之循于腹者。会于咽喉。而散于脉外也。夫冲脉之循于背者注于经。其浮而外
循于腹者。至胸中而散于脉外之气分。故脉不通则气因之。而喘动应手。谓脉逆于胸之下。而气因病于胸之上。喘动应
手者。人迎气口。喘急应手也。倪冲之曰。分别冲脉之有挟脊循腹。故曰随腹直上。则气因之。）寒气客于背俞之脉则
脉泣。脉泣则血虚。血虚则痛。其俞注于心。故相引而痛。按之则热气至。热气至则痛止矣。（此言太阳为炅热之气。虽
寒客于经俞。得气至则痛止矣。背俞之脉者。足太阳之脉也。太阳之脉循于背。而五脏六腑之俞。皆注于心。故相引心

痛而闭不通矣。（此承上文而言小肠之邪。不得后泄而为热闭也。热气者。寒气稽留而化热也。小肠为赤肠。乃心脏之府。

气乱。劳则气耗。思则气结。九气不同。何病之生。（问寒热七情。皆伤人气。而气有上下消耗之不同。是何病之所生也。）
岐伯曰。怒则气逆。甚则呕血及飧泄。故气上矣。（怒为肝志。肝主藏血。怒则肝气上逆。故甚则呕血。木气乘脾。故及
为飧泄。脾位中州。肝脏居下。故呕血飧泄。皆为气上。）喜则气和志达。荣卫通利。故气缓矣。（喜乃阳和之气。故志

外之腠理。汗乃荣血之阴液。夫气为阴之固。阴为阳之守。炅则腠理开。汗大泄。则阳气从而外泄矣。）惊则心无所倚。
神无所归。虑无所定。故气乱矣。（惊则心气散而无所倚。神志越而无所归。思虑惑而无所定。故气乱矣。）劳则喘息汗

Huangdi asked, "I have heard that those who are good at discussing the Way of Heaven must have verification in human beings; those who are good at discussing ancient history must align with the present; and those who are good at discussing human affairs must find confirmation within themselves. In this way, the Dao will not be confused, and one can reach the ultimate principles of its essential laws. This is what is called 'clarity' (The Classic states: Injury to Qi causes pain. Pain occurs in the有形 [form/structure] body, but the injury originates from the无形 [formless] Qi aspect. All diseases arise from cold-heat pathogens and the Seven Emotions, and manifestations appear in the Zang-Fu organs and meridians. By listing pains to discuss, the principles of all hundred diseases are thus revealed. If one can integrate and understand this Dao, one will be clear and not confused. Therefore, Huangdi said: One who knows the Way of Heaven, if verified in humans; one who knows the past, if aligned with the present; one who is good at discussing humanity, if sufficient within oneself. In this way, the Dao is not confused, and the extremes of essential laws are known. This is called 'understanding the Dao'.) Now I ask you, Master, hoping to hear methods that can be known through inquiry, seen through observation, obtained through palpation, and verified in oneself, thereby clarifying doubts. May I hear them?" (The Canon states: Knowing one method makes a common physician; knowing two makes an excellent physician; knowing three makes a divine physician. Mastering these three allows one to observe colors, palpate pulses, and inquire about illnesses. Thus, Huangdi wishes to hear the verification of these three correspondences to enlighten the unknown.) Qibo bowed twice and kowtowed, replying, "What question do you ask?" (Requesting the premise of the inquiry.) Huangdi said, "I wish to hear why sudden pain in the five Zang organs occurs, and what Qi causes it." Qibo replied, "Meridian Qi flows continuously, circling around without rest. When Cold pathogen enters the meridians, it causes stagnation and sluggishness, preventing smooth flow. If it lodges outside the vessels, blood volume decreases; if it lodges inside the vessels, Qi mechanism becomes obstructed. Hence, sudden pain occurs." (Qi flows like a circle without end. When Cold invades, it coagulates and stagnates. Lodging outside vessels causes contraction and reduced blood; lodging inside causes vessel fullness and Qi obstruction, leading to sudden pain. Zhang Zhaohuang stated: Qi is Yang, Blood is Yin; Qi is formless, Blood is formed; Qi moves outside vessels, Blood moves inside. Lodging outside reduces blood; lodging inside obstructs Qi. This correctly describes the key interaction between Form and Qi.)
Huangdi said, "This pain sometimes stops suddenly, sometimes persists severely, sometimes is too painful to press, sometimes stops when pressed, sometimes pressing brings no relief, sometimes pulsation is felt under the hand, sometimes heart and back pain radiate to each other, sometimes hypochondrium and lower abdomen pain radiate to each other, sometimes abdominal pain radiates to the inner thighs, sometimes pain lingers for days forming accumulations, sometimes sudden severe pain causes unconsciousness with recovery after a while, sometimes pain accompanies vomiting, sometimes abdominal pain accompanies diarrhea, sometimes pain accompanies constipation. All these pains differ in form. How should they be distinguished?" (Form refers to syndrome. Meaning that general syndromes differ; how to distinguish them?) Qibo said, "When Cold lodges outside the vessels, the vessels become cold. Cold causes contraction and curling, which leads to tension and cramping, pulling on small collaterals externally, causing sudden pain. Upon receiving warmth (Jiong), pain stops immediately. If repeatedly struck by Cold, pain lasts long." (Chù means bent. Cold coagulates blood, causing vessel contraction. Vessel contraction leads to tension, pulling small collaterals. Meridians are internal; floating external ones are collaterals. Internal and external tension causes sudden pain. Jiong Qi is Taiyang Qi. Vessels cold receive Yang heat, relaxing tension, so pain stops. If Cold returns, Yang is injured, so pain persists. Mo Zijin said: Taiyang is like the noon sun, governing all Yang Qi, the most intense heat. Receiving heavenly Cold, transformed by bodily Yang into heat, pain stops immediately.)
When Cold lodges inside the meridians, it fights with Warmth (Jiong), causing vessel fullness. Fullness leads to pain that cannot be pressed. Cold stagnates, Warmth rises, vessels swell, and Qi/Blood disorder, causing severe pain unresponsive to pressure. (Ying Blood moves inside vessels, Wei Qi moves outside. Cold in vessels fights Yang, causing blood/Qi saturation and vessel fullness, making pain unpressable. Cold stagnates inside, Yang rises only, blood/Qui cannot guide each other, causing disorder.)
When Cold lodges between the stomach/intestines and below the membrane source (Moyuan), blood cannot disperse, small collaterals tighten and pull, causing pain. Pressing disperses blood/Qi, stopping pain. (Moyuan connects to stomach/intestines, a lipid membrane, also the collateral tissue of Qi aspect. *Jin Gui Yao Lue* says: Collateral (Cou) is where Sanjiao meets Yuanzhen; Li is texture of skin/organs. External is skin/muscle Couli; internal is Moyuan connecting organs. Both are where Sanjiao meets Yuan Qi. Cold here pulls internal small collaterals, causing pain. Pain is Yin, Qi is Yang, Meridians are Yin. This chapter discusses pain as pathogen injuring meridians. Pathogen in external Qi aspect forcing meridions: relieved by warmth or pressure, as Cold dissipates easily with Qi. Pathogen entering meridians: severe pain unpressable, or pressure useless, as Yin pathogen is hard to dissipate. Pathogen in Moyuan Qi aspect pulling small collaterals: pressure stops pain. Zhang Zhaohuang said: Pathogen outside muscle Couli pulls external collaterals; pathogen outside Moyuan pulls internal collaterals. Moyuan contains blood collaterals.)
When Cold lodges in the paravertebral vessels, it is deep; pressure cannot reach, so pressing is useless. (Paravertebral vessels are Fu Chong vessels. Fu Chong runs up along the back interior; pathogen here is deep, unreachable by pressure. Ni Chongzhi said: Deep means pathogen in paravertebral Chong is deep; in abdominal Chong, it is superficial.)
When Cold lodges in the Chong Mai, which starts at Guanyuan and ascends straight up the abdomen, the vessels become obstructed. Obstruction causes Qi to follow suit, resulting in pulsation felt under the hand. (This discusses Chong Mai running in abdomen, meeting throat, scattering to external Qi. Back Chong injects into meridians; abdominal Chong scatters to chest external Qi. Obstruction causes Qi disorder, pulsation felt. Renying/Kouci pulses rapid. Ni Chongzhi said: Distinguishing Chong's paravertebral vs abdominal paths explains 'ascending straight up', hence Qi follows.)
When Cold lodges in the Back-Shu vessels, blood stagnates. Stagnation causes blood deficiency, deficiency causes pain. Shu points connect to Heart, so heart and back pain radiate. Pressing brings heat, stopping pain. (Taiyang governs Yang heat. Even if Cold lodges in Shu, arrival of heat stops pain. Back-Shu vessels are Foot-Taiyang. Taiyang runs on back; Zang-Fu Shu points connect to Heart. Radiating heart pain. Heart is Yang among Yang, matching Taiyang. Pressure brings heat, stopping pain.)
When Cold lodges in Jueyin vessels, which link the genitalia and attach to Liver, blood stagnates and vessels tense inside, causing radiating pain between hypochondrium and lower abdomen. (Liver governs Blood. Cold in Jueyin causes blood stagnation/tension. Liver channel distributes to hypochondrium/genitalia. Radiating pain. Ni Chongzhi said: Zang-Fu Shu/Ying originate in Chong, store in Jueyin Liver. Cold injures Ying, lodging in Chong/Shu/Jueyin.)
Juevi Qi lodges in the inner thigh, Cold reaches upper lower abdomen. Blood stagnates below, pulling together, causing abdominal pain radiating to inner thighs. (Cold above, Jueqi below, pulling each other. Jueyin channel reaches lower abdomen, runs inner thigh. Radiating pain. Meridian Qi connects up/down, pathogen/righteousness pull causing pain.)
When Cold lodges in Xiaochang (Small Intestine) Moyuan and collaterals, blood stagnates, cannot enter large meridians, Qi/Blood stagnate, forming accumulation over time. (Moyuan has blood collaterals. Cold in Moyuan collaterals cannot enter large meridians, forming accumulation. *Bai Bing Shi Sheng Pian*: Empty pathogen enters Luo, pain in muscle, intermittent, then affects large meridians. Stays in exterior of gut/Moyuan, lodges in vessels, stagnates, forms accumulation. External/internal collaterals must turn to large meridians for metabolism. Stagnation in collaterals forms accumulation over time. Suxi = long stagnation; Xi = stop; Da Jing = large collaterals of Zang-Fu.)
When Cold lodges in the Five Zang, Yin Qi rebels and leaks upward, Yin exhausts, Yang fails to enter, causing sudden severe pain, unconsciousness. If Qi returns, life is saved. (Cold in Zang, Yin Qi rebels/leaks, exhausting Yin internally. Yang heat fails to enter, damaging interior Qi, causing sudden pain/unconsciousness. Return of Yin/Yang Qi saves life.)
When Cold lodges in stomach/intestines, Qi rebels upward, causing pain and vomiting. (Cold in gut/stomach, exits via stomach upward, causing pain/vomit. Note: Pathogen in Zang resolves by flowing to Fu; in Gut/Stomach resolves by exiting downward. Here, Zang/Fu pathogen exits upward, indicating disease Qi does not enter meridians.)
When Cold lodges in Small Intestine, it fails to consolidate feces, causing diarrhea and abdominal pain. (Cold in Small Intestine enters intestine, failing to form accumulation, causing diarrhea/pain. Yang Yuanru said: Pathogen in Moyuan collaterals turns to large meridians, entering intestine. Pathogen entering meridians flows to Fu.)
When Heat stays in Small Intestine, intestinal pain occurs. Damp-Heat scorches fluids, causing thirst, hard dry stool unable to pass, leading to painful constipation. (Continuing: Small Intestine pathogen fails to exit downward, becoming Heat closure. Heat arises from Cold stagnation transforming via Yang heat. Small Intestine is Red Intestine, Fu of Heart, transforms to Heat via Fire. Dan refers to wasting-thirst. Small Intestine governs fluids; heat consumes fluids into Dan-Heat. Jiao is fire's nature; feeling fire heat causes thirst. Fluid loss/dryness makes food hard/dry, unable to pass, causing painful blockage. Yang Yuanru said: Chapter discusses Cold, ends with Heat line, meaning Cold stagnation transforms to Heat via Yang.)
Huangdi said, "What is meant by 'known through speech'? What is meant by 'visible through observation'?" (Speech-known: knowing location via inquiry. Visible: seeing disease via color.) Qibo said, "Zang-Fu have fixed areas. Observing five colors: Yellow/Red indicate Heat; White indicates Cold; Blue/Black indicate Pain. This is 'visible through observation'." (Zang-Fu colors appear on face, each ruling an area. Observing colors reveals disease. Heat shows Yellow/Red; Cold coagulates blood, showing pale/loss of color. Blue/Black are Yin-Cold stagnation colors, indicating pain.)
Huangdi said, "What is meant by 'obtainable through palpation'?" (Palpating pulse to find disease.) Qibo said, "Observe the pulse governing the disease. If firm with blood stasis, or sunken/depressed, both can be obtained by palpation." (Pulse governing disease is the pathological pulse of Zang-Fu. Firm/blood stasis indicates Excess pathogen; Sunken indicates Deficient righteous Qi. Both Excess/Deficiency can be palpated.)
Huangdi said, "Excellent. I know all diseases arise from Qi." (Cold/Heat movement is Heaven's Yin/Yang; Joy/Anger Seven Emotions are Human Yin/Yang. Listing pain discusses Yin/Yang Cold/Heat, knowing all diseases arise from Qi. Dong Zhongshu: Heaven has seasons, Humans have emotions. Zhang Zhaohuang: Wise nourish life following seasons/warmth, harmonizing emotions/rest, preventing severe illness/hundred diseases.)
Anger causes Qi to rise; severely, hematemesis and undigested diarrhea occur, so Qi goes up. (Anger is Liver emotion; Liver stores Blood. Anger causes Liver Qi rebellion, severe hematemesis. Wood attacks Spleen, causing undigested diarrhea. Spleen central, Liver inferior; vomiting/diarrhea are Qi rising.)
Joy causes Qi to harmonize, will to reach, Ying/Wei to flow freely, so Qi relaxes. (Joy is Yang harmony; will harmonizes/reaches, Ying/Wei unblocks, Qi relaxes/slow.)
Sorrow causes Heart Tie to tighten, Lung leaves to raise, Upper Jiao blocked, Ying/Wei not dispersed, Heat stays middle, so Qi consumes. (Heart Qi merging with Lung causes sorrow. Heart sorrow tightens Heart Tie. Heart Tie connects to Lung; tightening raises Lung leaves. Lung governs Qi/Upper Jiao/Ying/Wei. Lung expands/leaves raise, blocking Upper Jiao, hindering Ying/Wei dispersion. Qi stagnates middle creating heat, failing to circulate, consuming Qi.)
Fear causes Essence to retreat; retreat blocks Upper Jiao; blockage returns Qi downward; return distends Lower Jiao, so Qi does not move. (Qi is Yang born in Water. Kidney is Water organ, stores Essence, source of Qi. Fear injures Kidney, Essence retreats, cannot rise. Danzhong is Sea of Qi, exits Lung for respiration, origin Lower Jiao. Essence retreats blocks Upper Jiao; blockage returns ascending Qi to Lower Jiao, distending it. Up/Down Qi fail to communicate, so Qi does not move.)
Cold closes Couli, Qi does not move, so Qi gathers/inwardly contracts. (Couli is muscle texture, Sanjiao Yuanzhen meeting place. Cold closes Couli, blocking Qi, gathering Qi inward.)
Heat opens Couli, Ying/Wei flow, sweat profusely, so Qi leaks outward. (Wei moves external Couli; sweat is Ying Yin fluid. Qi secures Yin; Yin guards Yang. Heat opens Couli, sweat leaks, Yang follows outward leak.)
Fright causes Heart to have no support, Spirit no return, Thought no certainty, so Qi disorders. (Fright scatters Heart Qi/support, Spirit wanders/returns, Thought confuses/certain, so Qi disorders.)
Labor causes panting/sweating, internal/external escape, so Qi耗 (consumes). (Labor injures Kidney Qi, panting internally; Yang张扬, sweating externally. Internal/external escape, Qi consumes.)
Thought causes Heart to retain, Spirit to return, Zheng Qi stays/stagnates, so Qi knots. (Responsibility is Heart; direction is Will; change due to Will is Thought. Thought retains Heart Spirit, Zheng Qi stays middle, Qi knots.)
