手阳明大肠经的经脉，起始于食指桡侧末端（食指的末端，商阳穴位于此处）。沿着食指的桡侧边缘上行，出于合谷穴两骨之间（合谷是穴位名称，位于这两块骨头之间）。向上进入两根肌腱之中（阳谷穴所在处）。沿着前臂的桡侧边缘上行（前臂的桡侧边缘，经过手阳明大肠经所分布的区域）。进入肘部外侧（曲池穴所在区域）。沿上臂外侧前缘上行，过肩部，出于肩峰前缘（肩峰是指肩部的骨骼，所以肩髃穴在此处。遇到骨头的尖端，所以也命名为肩髃骨）。向上出于柱骨（大椎穴）的交会处（《气府论》注解说：柱骨的交会，是天鼎穴。位于颈部缺盆上方，直对扶突、气舍穴后方，同身寸半寸处）。向下进入缺盆，联络肺脏（肺是大肠的表里配合脏腑，所以大肠经络脉联系于肺）。向下穿过膈肌，归属于大肠（手阳明大肠经与手太阳小肠经互为表里，所以说它络肺而属大肠）。它的分支，从缺盆上行至颈部（喉结后方称为颈，颈后称为项）。贯穿面颊（颊，指面部两侧）。进入下齿龈中，复出挟口唇周围，在人中穴交叉（人中，又名水沟，位于鼻柱下方）。左侧经脉走向右侧，右侧经脉走向左侧，上行挟持鼻孔两侧（手阳明大肠经从此处交入足阳明胃经）。这条经脉发生异常变动就会生病（手阳明大肠经通常多气少血，现在气先发病，这叫做“是动病”）。症状包括牙齿疼痛、颧骨部位肿胀（颧指颧骨突出的部分）。这条经脉主要主管津液代谢失常所生的疾病（血液受气的影响而发病，这是气所生成的病变，所以说“所生病”。手阳明大肠经的气血通常比较旺盛，这是人体的常态。也有不同于常态的情况，《灵枢经》说：手阳明大肠经上部，如果气血旺盛，胡须就美观；如果血少气多，则面色晦暗无光；如果气血都少，就没有胡须。手阳明大肠经下部，如果气血旺盛，腋下的毛发就美观，手部皮肤肌肉温暖；如果气血都少，手部就消瘦发冷。由此可以知道手阳明大肠经气血的多少情况）。症状还包括眼睛发黄、口干、鼻塞流涕或出血（王冰说：鼻中流出清水叫鼽，流出血液叫衄）。咽喉肿痛闭塞，肩前部疼痛，食指和拇指疼痛且活动不便。邪气有余时，经脉经过的部位会出现发热肿胀；正气不足时，会出现寒战且难以恢复。（栗，即战栗。阴气盛，阳气不足，就会发生寒战）。实证时，人迎脉比寸口脉大三倍；虚证时，人迎脉反而小于寸口脉。
手阳明大肠经的别络，名叫偏历，距离腕横纹三寸，别行进入手太阴肺经。它的分支，向上经过肘部，沿着手臂，乘于肩部，上行至曲颊，遍行面部。它的另一分支，进入耳中，与宗脉相会合。实证时出现龋齿、耳聋；虚证时出现牙齿寒冷、痹阻隔塞。治疗取用该别络的穴位。
手阳明大肠经的筋，起始于食指和拇指的末端。结聚于手腕上方，沿着手臂，向上结聚于肘部外侧。向上结聚于肩部。它的分支，环绕肩胛，挟持脊柱。直行者，从肩部上行至颈部。它的分支，上行至面颊，结聚于下巴（顽通颏）。直行者，向上出手太阳小肠经之前，上行至左额角，联络头部，下行至右下颌。其病症发生在经脉经过的部位，表现为支撑性疼痛，以及转筋（肌肉痉挛），肩部不能抬起，颈部不能左右转动。治疗采用燔针劫刺法，以病情好转为次数标准，以痛点作为腧穴。这种病叫做孟夏痹。
邪气侵犯手阳明大肠经的络脉，使人气机壅满，胸中喘息，胁肋支撑胀满，胸中发热。针刺手食指指甲角旁，距离指尖如韭菜叶宽度的地方各一穴（商阳穴）。左病取右穴，右病取左穴，大约一顿饭的时间就好了。
邪气侵犯手阳明大肠经的络脉，使人耳聋，时常听不见声音。针刺商阳穴可立即听见声音；如果无效，针刺中指指甲角与肉交接处，也可立即听见声音。如果仍然听不见声音，就不能针刺。耳中有风声作响的，也按这种方法针刺。左病取右，右病取左。如果手阳明经的穴位无效，针刺经过耳朵前方露出体表的经脉穴位。
热病表现为手臂疼痛的，针刺手阳明大肠经和手太阴肺经的穴位，出汗后病止。
手阳明大肠经，从手指走向头部，长度五尺，左右共一丈。共有四十个穴位。

The meridian of Hand-Yangming Large Intestine originates at the radial end of the index finger (the end of the index finger, where Shangyang LI-1 is located). It follows the radial border of the finger, emerges between the two bones at Hegu LI-4 (Hegu is an acupoint name, located between these two bones). It ascends into the space between two tendons (where Yanggu SI-2 is situated). It follows the radial border of the forearm (the radial border of the forearm, traversing the area distributed by the Hand-Yangming Large Intestine meridian). It enters the lateral aspect of the elbow (the area of Quchi LI-11). It ascends along the anterior border of the lateral aspect of the upper arm, passes the shoulder, and emerges from the anterior border of the acromion (the acromion refers to the bone of the shoulder, so Jianliao TE-14 is located here. Meeting the tip of the bone, it is also named Jianliao bone). It ascends to emerge at the intersection of the pillar bone (the Dazhui GV-14) (Note in *Qi Fu Lun* states: The intersection of the pillar bone is Tianding TE-16. Located above the clavicular fossa on the neck, directly posterior to Futu TE-16 and Qishe ST-10, half cun using the body-cun method). It descends into the supraclavicular fossa (Quepen), connects with the Lung (The Lung is the interior-exterior partner of the Large Intestine, so the Large Intestine meridian network connects to the Lung). It descends through the diaphragm and belongs to the Large Intestine (Hand-Yangming Large Intestine meridian is exterior-interior related to Hand-Taiyang Small Intestine meridian, thus it networks with the Lung and belongs to the Large Intestine). Its branch rises from the supraclavicular fossa to the neck (the area behind the laryngeal prominence is called the neck, the back of the neck is called the nape). It penetrates the cheek (cheek refers to the sides of the face). It enters the lower gum, re-emerges flanking the mouth, and crosses at Renzhong (Renzhong, also known as Shuigou, is located below the philtrum). The left meridian flows to the right, and the right meridian flows to the left, ascending to flank both nostrils (Hand-Yangming Large Intestine meridian intersects with Foot-Yangming Stomach meridian from here). When this meridian undergoes pathological changes, disease occurs (Hand-Yangming Large Intestine meridian typically has abundant Qi and scarce Blood; when Qi is diseased first, this is called "Shi Dong" [Disease caused by meridian movement]). Symptoms include toothache and swelling of the zygomatic bone (zygoma refers to the prominent bone of the cheek). This meridian primarily governs diseases generated by disorders of Jin Ye (Body Fluids) metabolism (Blood is diseased due to Qi, which is generated by Qi, hence it is called "Suo Sheng Bing" [Diseases generated by the meridian]. The Qi and Blood of Hand-Yangming Large Intestine are typically abundant, which is the normal state of humans. There are exceptions. *Ling Shu* states: In the upper part of Hand-Yangming, if Qi and Blood are abundant, facial hair is beautiful; if Blood is scarce and Qi is abundant, the complexion is dark; if both are scarce, there is no facial hair. In the lower part, if Qi and Blood are abundant, axillary hair is beautiful and hand skin/muscles are warm; if both are scarce, hands are emaciated and cold. From this, one can know the abundance or scarcity of Qi and Blood in Hand-Yangming Large Intestine). Symptoms also include yellow eyes, dry mouth, rhinorrhea or epistaxis (Wang Bing said: Clear fluid from the nose is Qiu, blood from the nose is Xu). Throat obstruction (Bi), pain in the anterior shoulder, pain and dysfunction of the index and thumb. When pathogenic factors are excessive, heat and swelling occur at the sites traversed by the meridian; when deficiency exists, chills occur that do not easily resolve (Li means shivering. Excess Yin and insufficient Yang cause chills). In excess patterns, the Renying ST-7 pulse is three times larger than the Cunkou pulse; in deficiency patterns, the Renying pulse is smaller than the Cunkou pulse.
The Luo-connecting vessel of Hand-Yangming Large Intestine is named Pianli LI-6. It is three cun distal to the wrist crease, diverges to enter Hand-Taiyin Lung meridian. Its branch ascends to the elbow, follows the arm, traverses the shoulder, ascends to the submandibular region, and spreads over the face. Another branch enters the ear and converges with the Zong Mai (Ancestral Vessels). In excess patterns, dental caries and deafness occur; in deficiency patterns, cold teeth and bi-syndrome with obstruction occur. Treatment involves selecting the divergent point.
The sinews of Hand-Yangming Large Intestine originate at the ends of the index and thumb. They knot at the wrist, follow the arm, and ascend to knot at the lateral elbow. They ascend to knot at the shoulder. Their branch winds around the scapula and flanks the spine. The straight branch ascends from the shoulder to the neck. Its branch ascends to the cheek and knots at the chin (Ken). The straight branch ascends anterior to Hand-Taiyang Small Intestine, ascends to the left frontal angle, networks the head, and descends to the right mandible. Diseases occur at the sites traversed, manifesting as supporting pain and muscle spasms (Zhuan Jin), inability to raise the shoulder, and inability to turn the head left or right. Treatment uses Fan Zhen Jie Ci (burning needle rapid puncture), with the number of sessions determined by clinical improvement, and painful points used as acupoints. This condition is called Meng Xia Bi (Early Summer Bi Syndrome).
When evil invades the Luo-connecting vessels of Hand-Yangming Large Intestine, it causes Qi stagnation, chest fullness, panting, hypochondriac distension, and chest heat. Puncture the corner of the nail on the index finger, one cun from the corner, on each side (Shangyang LI-1). Treat left with right, right with left, resolving after about the time it takes to eat a meal.
When evil invades the Luo-connecting vessels of Hand-Yangming Large Intestine, it causes deafness and intermittent hearing loss. Puncturing Shangyang LI-1 restores hearing immediately; if ineffective, puncture the junction of the nail and flesh on the middle finger to restore hearing immediately. If hearing does not return, puncture is contraindicated. For wind sensation in the ear, treat similarly. Left treated with right, right with left. If Hand-Yangming points fail, puncture the meridian emerging anterior to the ear.
For heat diseases presenting with arm pain, puncture Hand-Yangming Large Intestine and Hand-Taiyin Lung meridians; sweating stops the disease.
Hand-Yangming Large Intestine Meridian runs from hand to head, five chi long, ten chi total for both sides. It contains forty acupoints.
