手太阴肺经的经脉，起始于中焦（位于胃脘部，肚脐上方四寸处）。向下联络大肠（“络”意为联系，此处指与本经相通的脏腑皆称为“络”，本经所属则称“属”）。返回来沿着胃的上口，向上穿过膈肌，归属于肺（膈膜位于心肺之下，前平鸠尾穴，后平第十一胸椎，周围相连，用以隔绝浊气，防止其上熏心肺）。“属”是指本经所管辖的部位。从肺系（即喉咙）横向出于腋下（中府穴旁边）。向下沿上臂内侧下行（经过天府、侠白穴的位置），行在手少阴心经和手厥阴心包经的前面（手三阴经中，太阴肺经在前，厥阴心包经在中，少阴心经在后）。向下经过肘窝，沿前臂内侧下行（从尺泽穴，经过孔最、列缺、经渠等穴的位置）。上行至桡骨茎突下方，进入寸口（手腕后方高起的骨头叫桡骨茎突，“下廉”指骨的下侧；寸口即太渊穴所在处）。上行至大鱼际，沿鱼际边缘行走（手腕前方肥肉隆起形如鱼的部位统称为“鱼”，鱼的后缘称为鱼际穴）。出于大拇指尖端（“端”即指尖，手太阴经止于少商穴）。其分支从腕后（列缺穴）直出，行至食指内侧边缘，出于其尖端（分支如同树枝，这是在正经之外旁通的络脉，从列缺穴直出至食指端，交接于少商穴而接手阳明大肠经）。
当这条经脉发生变动时，会出现肺部胀满，膨膨作响并伴有气喘咳嗽的症状（“动”指变化）。缺盆中疼痛（缺盆虽是十二经脉通行的道路，但肺经在此处尤为接近）。严重时两手交叉按压心胸部位，出现昏闷感（瞀，音茂，意为木痛麻木不仁）。这被称为臂厥。本经主治肺脏所发生的疾病（本篇凡涉及五脏，都各自说明该脏所生的疾病；凡涉及六腑，则或言气，或言血，或言脉，或言筋，或言骨，或言津液，其所生的疾病，本来各有主导）。咳嗽，上气喘急，口渴心烦，心胸满闷，手臂内侧前缘疼痛，手足心发热（“渴”当作“喝”，指呼吸声粗急。手太阴之别脉直入掌中，所以出现痛厥和掌中热）。肺气盛有余，则肩背疼痛，容易出汗，易受风寒侵袭（风寒在体表）。小便频数且量少（邪气损伤了肺气）。肺气虚，则肩背疼痛，怕冷，气短不足以呼吸，尿液颜色改变（金衰则水涸）。对于上述各种疾病，实证用泻法，虚证用补法，热证用疾刺法（气至迅速），寒证用留针法（气至缓慢），脉陷下的用灸法（阳气内衰，脉搏不起），不虚不实者，取本经治疗（疾病有不因气血虚实，而只是逆乱于经脉的，则应当顺着经脉所在，或用药物，或用针刺艾灸来治疗）。脉象盛大，寸口脉比人迎脉大三倍；脉象虚弱，则寸口脉反而小于人迎脉（寸口主阴，所以肺气盛时寸口脉比人迎脉大三倍，虚时反而小。人迎穴在结喉旁一寸五分，是三阳脉气汇聚之处）。
手阳明大肠经，起始于食指尖端（穴位名商阳）。沿食指上侧边缘上行（经过二间、三间穴）。出于合谷穴两骨之间（合谷在大拇指和食指后的歧骨间）。上行进入两筋之中（阳溪穴）。沿前臂上侧边缘进入肘外侧（经过曲池、五里、臂臑等穴的位置）。上行肩部，出于肩峰前缘（肩髃、巨骨穴处）。上行出于柱骨（颈项根部为天柱骨，六条阳经都交会于督脉的大椎穴，这叫“会上”）。向下进入缺盆，联络肺，向下穿过膈肌，归属于大肠（位于脐旁天枢穴的分野，属于大肠，与肺互为表里）。其分支从缺盆上行颈部，贯穿面颊（经过天鼎、扶突穴的位置）。进入下齿中，返回出来夹持口唇，在人中穴左右交叉（由人中穴左右互交）。上行夹持鼻孔（自禾髎穴交接于迎香穴）。
当这条经脉发生变动时，会出现牙齿疼痛、颈部肿胀。本经主治津液所发生的疾病（凡是腹泻或便秘，都是津液生成的疾病）。眼睛发黄，口干，鼻出血，咽喉肿痛，肩前部疼痛，大拇指和食指疼痛且活动不便（手阳明之别脉合于宗脉，所以眼睛发黄，其他各种疾病，都是本经经脉所覆盖的范围）。气有余，则经脉经过的地方出现热肿；气虚，则畏寒战栗，不易回暖（不易温也）。对于上述各种疾病，实证用泻法，虚证用补法，热证用疾刺法，寒证用留针法，脉陷下的用灸法，不虚不实者，取本经治疗（义理同前）。脉象盛大，人迎脉比寸口脉大三倍；脉象虚弱，则人迎脉反而小于寸口脉（人迎主阳，所以手阳明脉候见于人迎）。
足阳明胃经，起始于鼻翼两侧，相交于鼻根（其脉左右互相交叉，鼻根也）。旁侧纳入太阳经的脉气（纳入也）。向下沿鼻外侧下行（即承泣、四白、巨髎等穴的位置）。进入上齿中，返回出来夹持口唇，环绕嘴唇，在下唇沟处交叉（任脉穴位名）。退后沿下颌角后下方出行于大迎穴（由地仓穴以下至大迎穴）。沿颊车穴，上行至耳前（下关穴）。经过客主人穴（足少阳经穴位名）。沿发际线（头维穴）。到达额颅（发际前督脉的神庭穴）。其分支，从大迎穴前下方人行迎穴（经穴名）。沿喉咙，进入缺盆，向下穿过膈肌，归属于胃，联络脾（此支从缺盆穴入内，下穿膈肌，当上脘、中脘的分野，属于胃，与脾互为表里）。其直行者，从缺盆下行，沿乳内侧（直下向外行者，从缺盆下行经过气户等穴，直至乳中、乳根穴）。向下夹脐（天枢等穴）。进入气街中（自外陵等穴，下行进入气街）。其分支，起于胃的下口（下脘的分野）。向下沿腹腔内部下行（经过足少阴肓俞的外侧）。下行至气街中与直行脉汇合（与直行脉在气街中复合）。由此下行，经过髀关，抵达伏兔，下行至膝盖髌骨中，沿小腿外侧边缘下行，下行至足背，进入中趾内侧间隙（髀关、伏兔都是膝上穴位名，自此由阴市等穴，经过犊鼻、巨虚、冲阳等穴的位置，然后循行内庭，进入中趾内侧间隙而出厉兑，足阳明经止于此）。其分支，在膝下三寸处分出，下行进入中趾外侧间隙（其分支自丰隆穴别行，进入中趾外侧间隙）。其另一分支，从足背分出，进入大脚趾间，出于其尖端（又一支从足背冲阳穴位置别行，进入大脚趾间，斜出至足厥阴肝经行间穴的位置，沿大脚趾出于其端，而接足太阴脾经）。
当这条经脉发生变动时，会出现洒洒然恶寒战栗（风邪胜的表现）。喜欢呻吟，频繁呵欠（胃气郁结的表现）。面色发黑（土病则水无所畏，所以黑色反见于颜面）。发病时厌恶人和火（邪气客居阳明，则热甚）。听到木器声音就惊恐不安（土恶木）。心中悸动，独自关门闭窗居住（阴阳相搏，阳气尽而阴气盛，所以想独自关门闭窗居住）。严重时想登上高处唱歌（阳气盛则四肢充实）。脱衣奔跑（热盛于身体）。肠鸣腹胀（肠胃雷鸣），这被称为骭厥（骭指足胫，阳明经脉所及，所以为厥逆）。本经主治血液所发生的疾病（中焦接受谷物，变化而赤成为血，所以阳明经主治血所生的疾病）。狂躁疟疾、温热病，出汗，鼻塞流涕或鼻出血，口唇生疮，颈部肿胀，咽喉肿痛（阳明热胜则狂，风胜则疟，温气淫溢，则汗出、鼻塞流涕、鼻出血、口唇生疮等症状。胗，指疮疡）。大腹水肿（土病则不能制水）。膝盖髌骨肿痛，沿胸部、乳房、气街、大腿、伏兔、小腿外侧、足背都疼痛，中趾不能活动（都是阳明经脉所覆盖的范围）。气盛，则身体前面都发热，如果胃气有余，则消化食物快，容易饥饿，尿液颜色黄（这是辨别阳明实热是在经还是在脏）。气不足，则身体前面都寒冷战栗，胃中有寒，则胀满（这是辨别阳虚寒证是在经还是在脏）。对于上述各种疾病，实证用泻法，虚证用补法，热证用疾刺法，寒证用留针法，脉陷下的用灸法，不虚不实者，取本经治疗（义理同前）。脉象盛大，人迎脉比寸口脉大三倍；脉象虚弱，则人迎脉反而小于寸口脉（脉的盛衰见于人迎）。
足太阴脾经，起始于大脚趾尖端（隐白穴）。沿脚趾内侧白色肉际行走，经过核骨后，上行至内踝前缘（行大都、太白等穴）。上行至小腿内侧，沿胫骨后缘，交出厥阴肝经的前面（自漏谷上行至地机、阴陵泉）。上行至膝大腿内侧前缘（股，大腿也；前廉，上侧也，当血海、箕门穴的位置）。进入腹部，归属于脾，联络胃（自冲门穴入腹内行，当中脘、下脘的分野，属于脾，联络胃）。向上穿过膈肌，夹持咽喉，连系舌根，散布于舌下（自胃脘上行至咽，连舌根，散舌下而终）。其分支，又从胃别出，上行穿过膈肌，注入心中（足太阴外行者，由腹而上，经府舍、腹结等穴，散布于胸中，止于大包穴；其内行而分支者，自胃脘别出，上行穿过膈肌，注入心中，而接手少阴心经）。
当这条经脉发生变动时，会出现舌根强直，进食则呕吐，胃脘痛，腹胀，经常嗳气（噫，嗳叹声），大小便通畅后感觉轻松舒服（脾气通也）。身体沉重。本经主治脾脏所发生的疾病。舌根疼痛，身体不能动摇，饮食不下，心烦，心下急痛（太阴脉分支者，上膈注心中，所以出现心烦心痛）。大便溏泄，瘕积，小便不通，黄疸，不能安卧（脾寒，则为溏泄；脾滞则为瘕；脾病不能制水，则为泄，为水闭；黄疸，不能卧）。站立时，大腿膝盖内侧肿胀厥冷，大脚趾不能活动（这些都是足太阴经脉所覆盖的范围）。对于上述各种疾病，实证用泻法，虚证用补法，热证用疾刺法，寒证用留针法，脉陷下的用灸法，不虚不实者，取本经治疗（义理同前）。脉象盛大，寸口脉比人迎脉大三倍；脉象虚弱，寸口脉仅小于人迎脉（脉的盛衰候于气口）。

The Hand-Taiyin Lung Meridian originates in the middle jiao (located at the epigastrium, four cun above the umbilicus). It descends to connect with the Large Intestine ("connect" implies linking; organs connected to this meridian are termed "luo", while those belonging to it are termed "shu"). Returning along the upper opening of the stomach, it ascends through the diaphragm and belongs to the Lung (the diaphragm is located below the heart and lungs, level with the Jiutui point anteriorly and the 11th thoracic vertebra posteriorly, surrounding and adhering to isolate turbid qi from steaming upwards to the heart and lungs). "Belongs" refers to the area governed by this meridian. From the lung system (i.e., the trachea/throat), it emerges horizontally from under the axilla (beside the Zhongfu point). Descending along the medial aspect of the arm (passing Tianfu and Xiabai), it runs anterior to the Hand-Shaoyin Heart Meridian and Hand-Jueyin Pericardium Meridian (among the three hand yin meridians, the Taiyin Lung is anterior, Jueyin Pericardium is intermediate, and Shaoyin Heart is posterior). It descends into the elbow, then along the medial aspect of the forearm (from Chize, passing Kongzui, Lieque, Jingqu). Ascending to the lower margin of the styloid process of the radius, it enters the Cun Kou (the high bone behind the palm is the styloid process; "lower margin" refers to the lateral side of the bone; Cun Kou is the location of the Taiyuan point). Ascending along the Thenar eminence (the fleshy prominence anterior to the wrist resembling a fish is collectively called "fish"; the posterior border of the fish is the Yuji point), it exits at the tip of the thumb (tip refers to the fingertip; the Hand-Taiyin meridian ends at the Shaoshang point). Its branch arises from behind the wrist (Lieque), goes straight out to the medial side of the index finger, and exits at its tip (branches are like twigs on a tree; this is a collateral vessel connecting outside the main channel, going from Lieque to the tip of the index finger, intersecting at Shaoshang to connect with the Hand-Yangming Large Intestine Meridian).
When this meridian undergoes pathological changes, it causes lung distension, fullness, wheezing, and coughing ("change" refers to alteration). Pain in the supraclavicular fossa (although the supraclavicular fossa is a pathway for all twelve meridians, the Lung meridian is particularly close here). In severe cases, the patient crosses their hands over the chest and experiences dizziness or confusion (Mao, pronounced Mao, means numbness and insensitivity). This is called Arm Jue. This meridian governs diseases generated by the Lung (In this chapter, for the five zang organs, each describes diseases generated by that organ; for the six fu organs, it mentions qi, blood, vessels, sinews, bones, or body fluids according to the case. The diseases generated have specific dominances). Cough, asthma, thirst, irritability, chest fullness, pain along the anterior medial aspect of the arm, and heat in the palms (Thirst should be read as "he," meaning coarse and urgent breathing. The divergent branch of the Hand-Taiyin enters the palm directly, hence causing pain, Jue, and palm heat). If Lung Qi is excessive, there is shoulder and back pain, sweating, and susceptibility to wind-cold (wind-cold is on the exterior). Frequent and scanty urination (pathogenic factors damage Lung Qi). If Lung Qi is deficient, there is shoulder and back pain, aversion to cold, shortness of breath, and changes in urine color (Metal deficiency leads to Water depletion). For these various conditions: excess is treated with draining, deficiency with tonifying, heat with rapid needling (qi arrives quickly), cold with retained needle (qi arrives slowly), sinking pulse with moxibustion (internal decline of Yang qi, pulse does not rise), and neither excess nor deficiency is treated by taking from the meridian itself (if the disease is not due to qi/blood excess or deficiency but merely rebellion within the meridian, one should follow the meridian's location, using herbs or acupuncture/moxibustion). An excess pulse shows the Cun Kou larger than the Ren Ying by three times; a deficient pulse shows the Cun Kou smaller than the Ren Ying (Cun Kou governs Yin; thus, when Lung Qi is excessive, Cun Kou is three times larger than Ren Ying; when deficient, it is smaller. Ren Ying is located 1.5 cun lateral to the laryngeal prominence, where the Qi of the three Yang meridians converges).
The Hand-Yangming Large Intestine Meridian originates at the tip of the index finger (Shangyang point). It follows the radial side of the finger (passing Erjian and Sanjian). It emerges between the two bones at Hegu (Hegu is between the metacarpals of the thumb and index finger). It ascends between the two tendons (Yangxi point). Following the radial aspect of the forearm, it enters the lateral aspect of the elbow (passing Quchi, Wuli, Binao). Ascending the shoulder, it emerges anterior to the acromion (Jianyu, Gugu points). Ascending further to the intersection of the vertebral column (the root of the neck is the Tian Zhu bone; the six Yang meridians converge at Dazhui of the Du Meridian, called "Huishang"). Descending into the supraclavicular fossa, it connects with the Lung, passes through the diaphragm, and belongs to the Large Intestine (at the Tianshu level lateral to the umbilicus, belonging to the Large Intestine, interior-exterior paired with the Lung). Its branch ascends from the supraclavicular fossa through the neck to the cheek (Tianding, Futu points). Entering the lower teeth, it returns to encircle the lips, crossing at the Philtrum (intersecting left and right at the Philtrum). Ascending to flank the nostrils (from Heliao to Yingxiang).
When this meridian undergoes pathological changes, it causes toothache and neck swelling. This meridian governs diseases generated by Body Fluids (diarrhea or constipation are diseases generated by fluid metabolism). Yellow eyes, dry mouth, nasal bleeding, throat obstruction, pain in the anterior shoulder, and pain/immobility of the thumb and index finger (The divergent branch of the Hand-Yangming merges with the Zong Mai, causing yellow eyes; other diseases are covered by this meridian). Excess Qi causes heat and swelling along the meridian path; deficiency causes chills that do not resolve easily. For these conditions: excess is drained, deficiency is tonified, heat is rapidly needled, cold retains the needle, sinking pulse uses moxibustion, and neither excess nor deficiency takes from the meridian (as explained before). An excess pulse shows Ren Ying larger than Cun Kou by three times; a deficient pulse shows Ren Ying smaller than Cun Kou (Ren Ying governs Yang; thus, Hand-Yangming pulse is observed at Ren Ying).
The Foot-Yangming Stomach Meridian originates at the nose, crossing at the nasal root (meridians cross left and right). It receives Qi from the Taiyang Meridian. Descending along the lateral nose (Chengqi, Sibai, Juliao). Entering the upper teeth, it returns to encircle the lips, crossing at Chengjiang (Ren Meridian point). Retreating along the mandible to Daying (from Dicang to Daying). Along Jiache, ascending anterior to the ear (Xiaguan). Passing Gueman (Foot-Shaoyang point). Along the hairline (Touwei). Reaching the forehead (Shenting of Du Meridian anterior to hairline). Its branch descends from Daying anterior to Renying (Jing-Main point). Along the throat, entering the supraclavicular fossa, descending through the diaphragm, belonging to the Stomach and connecting with the Spleen (this branch enters internally from Qupen, passes the diaphragm at Shangwan/Zhongwan, belongs to Stomach, exterior-interior with Spleen). Its main trunk descends from the supraclavicular fossa along the medial breast (descending externally from Qupen via Qihu to Ruzhong, Rugen). Descending flanking the umbilicus (Tianshu). Entering the Qijie (from Wailing downwards). Its branch originates from the lower stomach (Xiaowan). Descending along the abdominal interior (lateral to Hushu of Foot-Shaoyin). Descending to Qijie to merge with the main trunk. Descending to Biguan, reaching Futu, descending to the knee patella, following the lateral tibia, descending to the dorsum of the foot, entering the medial space of the middle toe (Biguan, Futu are knee points; passing Yingshi, Dubi, Zusanli, Chongyang, Neiting, exiting at Lidui; Foot-Yangming ends here). Another branch separates at three cun below the knee (Fenglong), entering the lateral space of the middle toe. Another branch separates from the dorsum (Chongyang), entering the space between the big toes, exiting at the tip (connecting to Foot-Taiyin Liver Meridian at Xingjian).
When this meridian undergoes pathological changes, it causes aversion to cold and shivering (Wind excess). Groaning and frequent yawning (Stomach Qi stagnation). Blackened face (Earth disease allows Water to dominate, so black appears on the face). Fear of people and fire (Pathogen in Yangming causes intense heat). Startle at the sound of wood (Earth fears Wood). Palpitations, desire to stay alone with doors/windows closed (Yin-Yang conflict, Yang exhausted, Yin dominant). Climbing high and singing (Yang excess makes limbs solid). Discarding clothes and running (Heat excess in body). Bowel sounds and abdominal distension, called Gan Jue (Gan refers to shin; Yangming covers this area, hence Jue Ni). This meridian governs diseases generated by Blood (Middle Jiao processes grain, transforms it into red blood; thus Yangming governs blood diseases). Manic malaria, warm pathogens, sweating, nasal congestion/bleeding, oral ulcers, neck swelling, throat obstruction (Yangming heat causes mania; wind causes malaria; warm qi causes sweating/nasal issues; Zhen means ulcer). Abdominal edema (Earth fails to control Water). Knee/patella swelling and pain, pain along chest, breast, Qijie, thigh, Futu, lateral leg, dorsum, immobility of middle toe (all covered by Yangming). Excess Qi causes heat in the anterior body; if Stomach Qi is excessive, digestion is fast, hunger is frequent, urine is yellow (distinguishing Yangming excess-heat in channel vs. organ). Deficient Qi causes cold/chills in the anterior body; Stomach cold causes distension (distinguishing Yang deficiency-cold in channel vs. organ). For these: excess drained, deficiency tonified, heat rapidly needled, cold retained, sinking pulse moxa, neither excess nor deficiency takes from meridian. Excess pulse: Ren Ying three times larger than Cun Kou; Deficient pulse: Ren Ying smaller than Cun Kou (pulse changes seen at Ren Ying).
The Foot-Taiyin Spleen Meridian originates at the tip of the big toe (Yinbai).

Ascending through diaphragm, flanking pharynx, connecting to tongue root, spreading under tongue (ascending from stomach to pharynx, connecting tongue root, spreading under tongue). Its branch separates from the stomach, ascends through diaphragm, pours into the Heart (External path: Fushhe, Fujie, etc., disperses in chest, ends at Dabao; Internal branch: from stomach, through diaphragm, pours into Heart, connecting Hand-Shaoyin Heart Meridian).
When this meridian undergoes pathological changes, it causes stiff tongue root, vomiting after eating, epigastric pain, abdominal distension, frequent belching (Yi means sighing), relief after defecation/passing gas (Spleen Qi flows). Heavy body. This meridian governs diseases generated by the Spleen. Tongue root pain, immobility, inability to eat, irritability, acute pain below heart (Branch pours into Heart, hence irritability/pain). Loose stools, masses, urinary retention, jaundice, inability to lie down (Spleen cold causes loose stools; stagnation causes masses; failure to control water causes retention/jaundice/inability to sleep). Swelling/cold in thigh/knee medial side, immobility of big toe (covered by Foot-Taiyin). For these: excess drained, deficiency tonified, heat rapidly needled, cold retained, sinking pulse moxa, neither excess nor deficiency takes from meridian. Excess pulse: Cun Kou three times larger than Ren Ying; Deficient pulse: Cun Kou slightly smaller than Ren Ying (pulse changes observed at Qikou).
The Hand-Shaoyin Heart Meridian originates in the Heart, emerging to belong to the Heart System (below the 5th thoracic vertebra; five connections: upper to Lung, middle to Heart, lower to Spleen/Liver/Kidney; thus Heart governs Qi of five Zang). Descending through diaphragm, connecting with Small Intestine (at Xiawan, 2 cun above umbilicus). Its branch ascends from Heart System, flanking pharynx, connecting to Eye System (ascends external to Ren Meridian, flanks pharynx, connects Eye System, merging at inner canthus).
