（是经起于商阳穴，终于迎香穴。）
大肠手阳明之脉，起于大指次指之端，循指上廉，出合谷两骨之间，上入两筋之间，循臂上廉，入肘外廉，
上外前廉，上肩，出 骨之前廉，上出于柱骨之会上，下入缺盆，络肺，下膈属大肠。其支者，从缺盆上颈贯
颊，入下齿中，还出挟口，交人中，左之右，右之左，上挟鼻孔。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。为此诸病
，盛则泻
之，虚则补之，热则疾之，寒则留之，陷下则灸之，不盛不虚以经取之。盛者人迎大三倍于寸口，虚者人迎反
小于寸口也。
大指次指者，手大指之次指，即第二指，名食指也。循指之指，正次指也。合谷，虎口穴也。肩端两骨间
为骨。肩HT 上际处为天柱骨。缺盆，足阳明胃经穴也。头茎为颈。耳以下曲处为颊。
手阳明经之脉，受手太阴之交，遂起于次指之端。循次指之商阳、二间、三间之上廉，出合谷穴，在两骨
之间。又上阳溪穴，即两筋之间。又循臂之上廉、偏历、温溜、下廉、上廉、三里，入肘外廉之曲池穴。上循
外之前廉，历肘 、五里、臂 ，以上肩之肩 穴。又出 骨之前廉，循巨骨穴，上出天柱骨之会，上会于
大椎。自大椎而下入缺盆，循足阳明经脉外络，绕肺脏。复下膈，当天枢之外，会属于大肠。其支者虽自偏历
而入，又自缺盆上行于颈，循天鼎、扶突上贯于颊，入下齿缝中，复出夹口两吻，相交于人中之内，左脉往右
，右脉往左，上挟鼻孔，循禾 、迎香而终，以交于足阳明胃经也。
手阳明大肠经的脉气，起始于食指末端，沿着食指的桡侧上行，出于合谷穴位于第一、二掌骨之间，向上进入两筋之间的凹陷处，沿着前臂桡侧上行，进入肘部外侧，沿上臂外侧前缘上行，到达肩部，出于肩峰前缘，向上出于大椎穴（诸阳经交会之处），向下进入缺盆，联络肺脏，向下穿过横膈，归属于大肠。它的分支，从缺盆上行至颈部，贯穿面颊，进入下齿中，再回出夹持口角，在人中穴处左右交叉，左侧经脉向右，右侧经脉向左，上行夹持鼻孔两侧。当本经发生病变时，会出现牙齿疼痛、颈部肿胀的症状。本经主要主管津液代谢异常所致的疾病，如目黄、口干、鼻塞流涕或鼻出血、咽喉肿痛闭塞、肩前部疼痛、食指疼痛且活动不利。若经气有余，则在其经脉循行部位出现热肿；若经气不足，则出现寒战且难以恢复。针对这些病症，实证用泻法，虚证用补法，热证用疾刺法，寒证用留针法，阳气下陷者用灸法，不虚不实者取本经穴位治疗。实证表现为人迎脉搏动比寸口大三倍，虚证则人迎脉搏动反而小于寸口。
所谓“食指”，即手的第二指。所谓“循指之指”，正是指食指。合谷穴位于虎口处。肩端两块骨头之间称为骨空（此处指肩井穴区域）。肩井穴上方的天柱骨位置即为天柱骨。缺盆是足阳明胃经的一个穴位。头颈部分为颈。耳下方的弯曲处为颊。
手阳明大肠经的脉气，承接自手太阴肺经的交接，于是起始于食指末端。沿着食商的商阳穴、二间穴、三间穴的上缘，出于合谷穴，位于两骨之间。又向上经过阳溪穴，即两筋之间的凹陷处。又沿着前臂的上缘，经过偏历、温溜、下廉、上廉、三里等穴，进入肘部外侧的曲池穴。向上沿着上臂外侧前缘，经过肘髎、五里、臂臑等穴，以上达肩部的肩髃穴。又出于肩髃穴前方的巨骨穴，向上出于天柱骨的大椎穴交会处，会上于大椎穴。自大椎穴向下进入缺盆，沿着足阳明胃经的外侧络脉，环绕肺脏。再向下穿过横膈，在天枢穴外侧，会合归属于大肠。其分支虽然从偏历穴分出，但又从缺盆上行至颈部，经过天鼎、扶突穴，向上贯穿面颊，进入下齿缝中，再复出夹持口角两旁，相交于人中的内侧，左侧经脉走向右侧，右侧经脉走向左侧，向上夹持鼻孔，经过禾髎、迎香穴而终结，从而与足阳明胃经相交接。
(This meridian starts at Shangyang (LI1) and ends at Yingxiang (LI20).)
The Large Intestine Hand-Yangming Meridian originates from the tip of the index finger, follows the radial border of the finger, emerges between the two bones at Hegu (LI4), ascends into the space between the two tendons, follows the radial border of the forearm, enters the lateral aspect of the elbow, ascends along the anterolateral border of the upper arm, reaches the shoulder, emerges from the anterior border of the acromion, ascends to meet at Dazhui (GV14, the intersection of all Yang meridians), descends into Quepen (ST12), connects with the Lung, passes through the diaphragm, and belongs to the Large Intestine. Its branch arises from Quepen, ascends to the neck, penetrates the cheek, enters the lower teeth, returns to emerge flanking the mouth, crosses at Renzhong (GV26), with the left meridian going to the right and the right meridian going to the left, ascending to flank the nostrils. When this meridian is affected, it causes toothache and neck swelling. This meridian primarily governs diseases related to fluid metabolism, such as yellow eyes, dry mouth, nasal congestion or epistaxis, throat obstruction, 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 course of the meridian; if deficient, there will be chills that do not resolve. For these conditions, excess is treated by reducing, deficiency by tonifying, heat by rapid needling, cold by retaining the needle, sinking Yang by moxibustion, and neither excess nor deficiency by selecting points from the meridian itself. Excess is indicated when the Renying pulse is three times larger than the Cunkou pulse; deficiency is indicated when the Renying pulse is smaller than the Cunkou pulse.
The "index finger" refers to the second finger of the hand. The phrase "following the finger" specifically refers to the index finger. Hegu is located in the thenar eminence (tiger's mouth). The space between the two bones at the shoulder end refers to the shoulder joint area. The Tianzhu bone above the Jianjing (GB21) point refers to the cervical spine. Quepen is an acupoint of the Stomach Foot-Yangming Meridian. The neck region is called Jing. The curved area below the ear is called Jia.
The Hand-Yangming Large Intestine Meridian receives transmission from the Hand-Taiyin Lung Meridian and thus originates from the tip of the index finger. It follows the Shangyang (LI1), Erjian (LI2), and Sanjian (LI3) points on the radial border of the index finger, emerges at Hegu (LI4) between the two bones. It then ascends to Yangxi (LI5), located between the two tendons. It continues along the radial border of the forearm, passing through Pianli (LI6), Wenliu (LI7), Xialian (LI8), Shanglian (LI9), and Sanli (LI10), entering Quchi (LI11) at the lateral aspect of the elbow. It ascends along the anterolateral border of the upper arm, passing through Zhou Liao (LI12), Wuli (LI13), and Binao (LI14), reaching the Shoulder Bone (Jianyu LI15) at the shoulder. It emerges from the anterior border of the Shoulder Bone, following the Juliao (LI16) point, ascends to meet at the Tianzhu bone (Dazhui GV14), converging at Dazhui. From Dazhui, it descends into Quepen, follows the lateral aspect of the Stomach Foot-Yangming Meridian's collateral network, surrounds the Lung, passes through the diaphragm, meets and belongs to the Large Intestine outside Tianshu (ST25). Its branch, although originating from Pianli, also ascends from Quepen to the neck, passing through Tianding (SI14) and Futu (LI18), penetrating the cheek, entering the lower teeth, emerging to flank the corners of the mouth, crossing internally at Renzhong (GV26), with the left meridian going to the right and the right meridian going to the left, ascending to flank the nostrils, following Heliao (LI19) and Yingxiang (LI20) to terminate, thereby connecting with the Stomach Foot-Yangming Meridian.
