（长二丈一尺，广四寸，当脐右回十六曲）《灵枢》曰∶手阳明之脉，起于大指次指之端
（商阳穴也），循指上廉（本节前陷中二间穴，本节后陷中三间穴也），出合谷两骨之间（合谷，穴名），上
入两筋之中（阳溪穴也），循臂上廉，入肘外廉（曲池穴也），上 外前廉，上肩出 骨之前廉（ 外前廉，
肘、五里、臂 也。肩端骨罅为 骨，以上肩 、巨骨也），上出于柱骨之会上（肩背之上，颈项之根，为
天柱骨，六阳皆会于督脉之大椎，是为会上），下入缺盆，络肺，下膈属大肠（自大椎而前，入足阳明之缺盆，
络于肺中，复下膈，当脐旁天枢之分。属于大肠，与肺相为表里也）；其支者，从缺盆上颈贯颊，入下齿中
（头茎为颈。耳下曲处为颊。颈中之穴，天鼎、扶突也），还出挟口，交人中，左之右，右之左，上挟鼻孔（
人中，即督脉之水沟穴，由人中而左右互交，上挟鼻孔者，自禾 以交于迎香穴也。手阳明经止于此，乃自
山根交承泣穴而接乎足阳明经也）。其别，名曰偏历，去腕三寸，别入太阴；其别者，上循臂，乘肩 ，上曲
颊偏齿；其
别者，入耳合于宗脉。实则龋、聋，虚则齿寒、痹隔，取之所别也（手阳明之络，名偏历，在腕三寸上侧间，
别走手太阴者也。按∶本经筋脉，皆无入耳上目之文，惟此别络有之。宗脉者，脉聚于耳目之间者也。龋齿，
蠹病也，此经上曲颊偏齿，入耳，络肺，下膈，故实则为齿龋耳聋，虚则为齿寒内痹而隔。治此者，当取所
别之偏历）。其正从手循膺乳，别于肩 ，入柱骨，下走大肠，属于肺，上循喉咙，出缺盆，合于阳明（大
肠与肺相表里，经脉亦为一合。手阳明之正，循胸前膺乳之间，其内行者，别于肩 ，入柱骨，出缺盆，下
走大肠，属于肺。其上者，循喉咙，复出缺盆，而合于阳明本经也）。其筋起于大指次指之端，结于腕，上循
臂，上结于肘外，上 ，结于 （大指次指之端，食指尖商阳之次也，历合谷，结于腕上阳溪之次，循臂上廉，
又结于肘外肘 之次，乃上 会，与足太阳之筋合，结于肩 ，此皆刚筋也）；其支者，绕肩胛，挟脊（此支
自肩 屈曲后行，绕肩胛，与手足太阳之筋合，两挟于脊）；直者，从肩 上颈（此直者，自肩 行巨骨，上
颈中天鼎、扶突之次）；其支者，上颊，结于 （此支者自颈上颊，入下齿中，上结于手太阳颧 之分）；直
者，上出手太阳之前，上左角，络头，下右颔（此直者，自颈出手太阳天窗、天容之前，行耳前，上额左角，
络头，以下右颔。此举左而言，则右在其中，亦如经脉之左之右，右之左也。故右行者，亦上额右角，交络于
头，下左颔，以合于太阳、少阳之筋）。是动则病齿痛，颈肿。是主津液所生病者，目黄口干，鼽衄喉痹，肩
前痛，大指次指痛不用。气有余，则当脉所过者热肿，虚则寒栗不复。盛者，人迎大三倍于寸口；虚者，人
迎反小于寸口也。
（大肠的长度为二丈一尺，宽度为四寸，位于肚脐右侧，呈十六个弯曲。）《灵枢》说：手阳明经的经脉，起始于食指末端（商阳穴），沿着食指上侧边缘（经过本节前凹陷处的二间穴，和本节后凹陷处的三间穴），出于合谷穴两骨之间（合谷是穴位名称），上行进入两根肌腱之中（阳溪穴），沿着前臂上侧边缘，进入肘部外侧边缘（曲池穴），上行至肘部外侧前缘，经过肩端骨之前的边缘（“肘、五里、臂臑”指肘部、五里穴、臂臑穴。肩端骨的缝隙称为“髃骨”，以上经过肩髃穴、巨骨穴），向上出于柱骨（天柱骨）的交会处（肩背之上，颈项根部，称为天柱骨，六条阳经都交会于督脉的大椎穴，这就是所谓的“会上”），向下进入缺盆，联络肺脏，向下穿过膈肌，归属于大肠（从大椎穴向前，进入足阳明胃经的缺盆，联络于肺中，再向下穿过膈肌，对应肚脐旁天枢穴的区域。归属于大肠，与肺互为表里）；它的分支，从缺盆上行至颈部，贯穿面颊，进入下齿中（头颈连接处为颈。耳下弯曲处为颊。颈部的穴位有天窗、扶突等），返回出来夹着口角，交叉于人中部，左侧经络走向右侧，右侧经络走向左侧，上行夹着鼻孔（人中部，即督脉的水沟穴，通过人中部左右交错，上行夹着鼻孔，是从禾髎穴交接于迎香穴。手阳明经终止于此，然后自山根交接承泣穴而连接足阳明经）。它的别络，名叫偏历，距离手腕三寸，别行进入手太阴肺经；它的另一支别络，向上沿手臂，经过肩部，上行至下颌角偏斜牙齿；它的又一支别络，进入耳朵，与宗脉汇合。实证表现为龋齿、耳聋，虚证表现为牙齿寒冷、痹阻不通，治疗应取用该别络（手阳明经的络穴名为偏历，在腕横纹上三寸的侧面，别行走向手太阴肺经。按：本经的正经和筋脉，都没有进入耳朵或上达眼目的记载，只有这条别络有。宗脉，是指汇聚在耳目之间的经脉。龋齿，是蛀牙病，此经上行至下颌角偏斜牙齿，进入耳朵，联络肺，向下穿过膈肌，所以实证表现为齿龋耳聋，虚证表现为牙齿寒冷内痹而隔塞。治疗这些病症，应当取用别出的偏历穴）。其正脉从手部沿着胸膺乳房部位，别行于肩部，进入柱骨，向下走行至大肠，归属于肺，向上沿着喉咙，出于缺盆，与阳明经相合（大肠与肺互为表里，经脉也构成一对合。手阳明经的正脉，沿着胸前膺乳之间，其内部行走的部分，别行于肩部，进入柱骨，出于缺盆，向下走行至大肠，归属于肺。其上行的部分，沿着喉咙，再复出缺盆，而与阳明本经相合）。其筋起于食指末端，结聚于手腕，向上沿手臂，向上结聚于肘部外侧，向上经过腋后，结聚于肩髃（食指末端的商阳穴，经过合谷，结聚于腕上的阳溪穴，沿手臂上侧，又结聚于肘外的肘髎穴，乃上至肩井会合，与足太阳膀胱经的筋相合，结聚于肩髃穴，这些都是刚硬的筋）；它的分支，绕行肩胛，夹持脊柱（此分支从肩髃屈曲后行走，绕行肩胛，与手足太阳经的筋相合，左右夹持于脊柱）；直行的部分，从肩髃上行至颈部（此直行部分，从肩髃经过巨骨穴，上行至颈部天窗、扶突穴的位置）；它的分支，上行至面颊，结聚于颧骨（此分支从颈部上行至面颊，进入下齿中，上行结聚于手太阳小肠经的颧髎穴区域）；直行的部分，上行出手太阳经之前，上行至左额角，联络头部，下行至右下颌（此直行部分，从颈部出手太阳经的天窗、天容穴之前，行于耳前，上行至额左角，联络头部，以下行至右下颌。这里举左侧来说明，右侧也在其中，也像经脉那样左交右、右交左。所以右侧的筋，也是上行至额右角，交错联络于头部，下行至左下颌，以合于太阳、少阳经的筋）。发生病变则出现牙齿痛，颈部肿胀。此经主要主管津液所生的疾病，如目黄、口干、鼻塞流涕或鼻出血、咽喉肿痛，肩前疼痛，食指疼痛且活动不利。气有余，则在其经脉经过的部位出现热肿；气虚则出现寒战且难以恢复。脉象盛大时，人迎脉搏动比寸口大三倍；脉象虚弱时，人迎脉搏动反而小于寸口。
(The large intestine is two zhang and one chi in length, four cun in width, located to the right of the navel, with sixteen curves.) The *Ling Shu* states: The Hand-Yangming [Large Intestine] meridian originates at the tip of the index finger (Shangyang LI-1), follows the radial border of the finger (passing through Erjian LI-2 in the depression proximal to the metacarpophalangeal joint, and Sanjian LI-3 in the depression distal to it), emerges between the two bones at Hegu LI-4 (Hegu is an acupoint name), ascends into the space between the two tendons (Yangxi LI-5), follows the radial border of the forearm, enters the lateral aspect of the elbow (Quchi LI-11), ascends to the anterior-lateral border of the elbow, passes anterior to the lateral edge of the shoulder bone (referring to the elbow, Wuli LI-13, and Binao LI-14. The gap at the end of the shoulder bone is called the 'Yu' bone; above this are Jianliao SI-14 and Jugu GB-21), ascends out from the meeting point of the vertebral column (the upper back and root of the neck are known as the Tianzhu bone; all six Yang meridians converge at Dazhui GV-14 on the Du vessel, hence termed the 'meeting place'), descends into the Supraclavicular Fossa (Quepen), connects with the Lung, descends through the diaphragm, and belongs to the Large Intestine (from Dazhui moving forward, entering the Quepen of the Foot-Yangming [Stomach] meridian, connecting within the Lung, then descending through the diaphragm, corresponding to the region of Tianshu ST-25 beside the navel. It belongs to the Large Intestine, forming an interior-exterior relationship with the Lung); its branch rises from the Supraclavicular Fossa to the neck, penetrates the cheek, and enters the lower teeth (the connection between head and trunk is the neck; the curved area below the ear is the cheek; acupoints in the neck include Tianding TE-16 and Futu LI-18), returns to emerge flanking the mouth, crosses at the Philtrum (Renzhong), where the left side crosses to the right and the right side crosses to the left, ascending to flank the nostrils (the Philtrum corresponds to Shuiguo GV-26 of the Du vessel; crossing left and right via the Philtrum and ascending to flank the nostrils involves the transition from He Liao SI-19 to Yingxiang LI-20. The Hand-Yangming meridian terminates here, then connects from Shanggen (root of nose) to Chengqi ST-1 to join the Foot-Yangming [Stomach] meridian). Its collateral is named Pianli (TE-6), located three cun above the wrist, diverging to enter the Hand-Taiyin [Lung] meridian; another branch ascends along the arm, traverses the shoulder, ascends to the angle of the jaw affecting the teeth; another branch enters the ear and converges with the Zong Mai (Major Collaterals). In excess conditions, there are toothache and deafness; in deficiency conditions, there are cold teeth and bi-syndrome obstruction. Treatment should target the divergent point (The collateral of the Hand-Yangming meridian is named Pianli, located on the dorsal-radial side three cun above the wrist crease, diverging to the Hand-Taiyin [Lung]. Note: Neither the main channels nor the sinews of this meridian have descriptions of entering the ear or reaching the eyes; only this collateral does. Zong Mai refers to vessels gathered around the eyes and ears. Tooth decay is a pestilence disease; since this meridian ascends to the jaw angle affecting teeth, enters the ear, connects with the Lung, and descends through the diaphragm, excess manifests as dental caries and deafness, while deficiency manifests as cold teeth, internal bi-obstruction, and blockage. To treat these, one should select the divergent Pianli). The main pathway from the hand follows the chest and breast region, diverges at the shoulder, enters the vertebral column, descends to the Large Intestine, belongs to the Lung, ascends along the throat, emerges at the Supraclavicular Fossa, and merges with the Yangming [Stomach] meridian (The Large Intestine and Lung are interior-exterior pairs, and their meridians form a pair. The Zheng [Regular] pathway of the Hand-Yangming meridian follows the anterior chest and breast; its internal course diverges at the shoulder, enters the vertebral column, emerges at the Supraclavicular Fossa, descends to the Large Intestine, and belongs to the Lung. Its superior course ascends along the throat, re-emerges at the Supraclavicular Fossa, and merges with the Yangming primary meridian). Its sinews originate at the tip of the index finger, knot at the wrist, ascend along the arm, knot at the lateral elbow, ascend to the axilla, and knot at Jianliao SI-14 (The tip of the index finger is Shangyang LI-1; passing Hegu LI-4, it knots at Yangxi LI-5 on the wrist, follows the radial forearm, and again knots at Zhouliao LI-11 on the lateral elbow. Then it ascends to meet at Jianjing GB-21, combining with the sinews of the Foot-Taiyang [Bladder] meridian, and knots at Jianliao SI-14; these are all rigid sinews); its branch winds around the scapula, flanking the spine (this branch curves after Jianliao SI-14, winds around the scapula, combines with the sinews of the Hand and Foot Taiyang meridians, and flanks the spine bilaterally); the straight portion ascends from Jianliao SI-14 to the neck (this straight part travels from Jianliao SI-14 through Gugu GB-21, ascending to Tianding TE-16 and Futu LI-18 in the neck); its branch ascends to the cheek, knotting at Quanliao SI-18 (this branch ascends from the neck to the cheek, enters the lower teeth, and ascends to knot at the region of Quanliao SI-18 of the Hand-Taiyang [Small Intestine] meridian); the straight portion ascends anterior to the Hand-Taiyang meridian, reaches the left frontal angle, connects to the head, and descends to the right mandible (this straight part exits anterior to Tianchuang TE-17 and Tianrong SI-17 of the Hand-Taiyang meridian, travels anterior to the ear, ascends to the left frontal angle, connects to the head, and descends to the right mandible. This description uses the left side as an example, implying the right side operates similarly, just as meridians cross left to right and right to left. Thus, the right-side sinews also ascend to the right frontal angle, interconnect at the head, and descend to the left mandible to combine with the sinews of the Taiyang and Shaoyang meridians). When the meridian is disturbed, symptoms include toothache and neck swelling. This meridian primarily governs diseases generated by fluids, such as yellow eyes, dry mouth, rhinorrhea or epistaxis, pharyngitis, pain in the anterior shoulder, and pain or dysfunction of the index finger. If Qi is in excess, there will be heat and swelling along the path of the meridian; if deficient, there will be chills that do not resolve. In excess pulse patterns, the Renying (ST-9) pulse is three times larger than the Cunkou (Radial artery) pulse; in deficiency, the Renying pulse is smaller than the Cunkou pulse.
