手阳明大肠经共有二十个穴位。其循行路线从商阳穴开始，经过二间、三间，到达合谷穴和阳溪穴，再经过偏历穴、温溜穴，下行至下廉穴、上廉穴和三里穴附近，经过曲池穴和肘髎穴，以及五里穴的行程，上行至臂臑穴和肩髃穴，最后到达巨骨穴。天鼎穴迂回向上至扶突穴，禾髎穴连接嘴唇，迎香穴靠近鼻子。
商阳穴位于食指内侧边缘。寻找二间穴时，在本节（指关节）前凹陷处取穴。三间穴在节后凹陷处取穴。合谷穴在手虎口歧骨之间。阳溪穴在上侧腕部横纹中。偏历穴在腕后三寸处。温溜穴在腕后五寸处。曲池穴前五寸为下廉穴。曲池穴前三寸为上廉穴。曲池穴前两寸为三里穴。曲池穴在屈肘时，尺骨鹰嘴与肱骨外上髁之间的纹路尽头。肘髎穴在大骨外侧近旁。在五里穴处，于肘上三寸向内寻找。臂臑穴在肘上七寸处测量。肩髃穴在肩端，举臂时取穴。巨骨穴在肩尖端向上行。天鼎穴在喉旁四寸处。扶突穴在天突穴旁五寸处。禾髎穴在水沟穴旁五分处。迎香穴在禾髎穴上一寸处。大肠经的穴位分布清晰明确。（左右两侧共四十个穴位）
足阳明胃经的脉气，起始于鼻翼两旁交于鼻根中部（山根），旁边会合太阳经的脉气，向下沿鼻外侧，上行进入齿中，再出来挟口环绕嘴唇下方，交会于承浆穴，然后沿腮后下方下行，出大迎穴，沿颊车穴，上行至耳前，经过客主人穴（上关穴），沿发际，到达额颅。其支脉，从大迎穴前方下行到人迎穴，沿喉咙，进入缺盆，向下穿过膈肌，属胃，络脾。其直行主干，从缺盆下行，沿乳内廉，向下挟脐，进入气街中。其另一支脉，起于胃口，向下沿腹里，下行至气街中与直行脉会合，然后向下经过髀关，抵达伏兔穴，下行至膝膑中，沿胫骨外侧下行，至足背，进入中趾内侧间隙。其又一支脉，从膝下三寸处分出，向下进入中趾外侧间隙。其又一支脉，从足背上分出，进入大趾间，出于大趾末端。当经脉之气发生变动时，会出现战栗恶寒，喜欢呻吟，频繁呵欠，面色发黑等症状。病发时则厌恶人与火，听到木器声音就惊恐不安，心中悸动，独自关门闭窗而居。严重时想登上高处唱歌，脱衣奔跑，腹部雷鸣作响且腹胀，这称为贲豚厥。本经主要主管血分所生的疾病，如狂证、疟疾、温热病、出汗、鼻塞流涕或鼻出血、口唇生疮，颈部肿胀、喉痹，大腹水肿，膝膑肿痛，沿胸、乳、气街、股部、伏兔、小腿外侧、足背均疼痛，中趾不能活动。经气盛实则身体前面发热，若胃气有余，则消化食物快且容易饥饿，小便颜色黄；经气不足则身体前面发冷颤抖，胃中有寒则胀满。对于这些病症，实证用泻法，虚证用补法，热证用疾刺法，寒证用留针法，阳气下陷用灸法，不虚不实则以本经取穴治疗。经气盛实时，人迎脉比寸口脉大三倍；经气虚弱时，人迎脉反而小于寸口脉。（“頞”音遏，指鼻根；“髀”音被，指大腿；“膑”音宾，指膝盖骨；“跗”音抚，指足背；“贲”音奔，通“奔”，指奔豚；“䐜”音嗄，指腹胀；“胗”音诊，通“疹”，指疮疡）
鼻的两旁称为“頞”。腮下称为“颔”。颔中间称为“颐”。腮上称为发际。发际前称为额颅。大腿内侧称为“髀”。髀前膝上隆起的肌肉处称为伏兔。伏兔后为髀关。挟持膝盖筋中间的称为膑。胫骨称为“胻”。足面称为跗。足阳明胃经受手阳明大肠经的交接，起始于鼻旁的迎香穴，上行并在鼻根处左右相交，经过睛明穴，向下沿鼻外侧，经过承泣、四白、巨髎等穴，上行进入齿中，再出来挟口，经过两吻的地仓穴，环绕嘴唇下方，左右相交于承浆穴，然后沿腮后下方下行，出大迎穴，沿颊车穴，上行至耳前，经过下关穴，过客主人穴，沿发际，行经悬厘、颔厌部位，经过头维穴，会合于额颅的神庭穴。其支脉，从大迎穴前方下行到人迎穴，沿喉咙，经过水突、气舍穴，进入缺盆，行于足少阴肾经俞府穴的外侧，向下穿过膈肌，当下脘、中脘的部位，属胃，络脾。其直行者，从缺盆向下，沿乳内廉，经过气户、库房、屋翳、膺窗、乳中、乳根、不容、承满、梁门、关门、太乙、滑肉门等穴，挟脐下行，经过天枢、外陵、大巨、水道、归来等穴，进入气街中。其支脉，从属胃的地方，起于胃的下口，沿腹里下行，经过足少阴肾经肓俞穴的外侧，在本经的里层，下行至气街中，与前一支脉在气街中会合。既然在气街中会合，便向下经过髀关，抵达伏兔，经过阴市、梁丘，下行进入膝膑中，经过犊鼻穴，下行沿足面名为跗的冲阳穴、陷谷穴，进入中趾外侧的内庭穴，至厉兑穴结束。其络脉的支别者，自膝下三寸处，沿三里穴外侧别行向下，经过上廉、条口、下廉、丰隆、解溪、冲阳、陷谷，以至内庭、厉兑而会合。又有一支脉，从足背上的冲阳穴别行，进入大趾间，出于足厥阴肝经行间穴的外侧，沿大趾下行出于其末端，以交于足太阴脾经。阳明经之气发生变动，则出现战栗恶寒的症状。因为阳明对应午时，阳气极盛而阴气加之，所以战栗恶寒。喜欢呻吟，是因为阳气郁结想要伸展出来。频繁呵欠，是阳气想要引而上行。面色发黑，是阴气加于上部。这是病在阳明经气的表现。病气至于经脉，即阳明经脉发病，则厌恶人与火，听到木声则惊恐不安。因为胃络上通于心，所以心中悸动。阴阳相搏，所以想要独自关门闭窗居住。阳气盛实则四肢充实，实则登高而歌。热盛于身，所以脱衣奔跑。阳明经脉向下穿过膈肌，属胃络脾，所以腹部雷鸣作响且腹胀。这是阳明经气逆乱于经脉，从而产生这些症状，所以说这是贲豚厥。大概阳明经脉沿胫骨外侧下行。有病气但未及于经脉的，有病在气分而表现出经脉症状的，有经脉之气兼夹他病的，有病气转入经脉的，所以说可以分开也可以合并论述。《本经》说：食物进入胃中，脉道通畅，血气才能运行。《平脉篇》说：水进入经脉，血液才能形成。胃是水谷之海，主要生成营血，所以本经主要主管血分所生的疾病，如狂证、温疟、出汗，这是因为胃气热而蒸发水液成汗。鼻塞流涕或鼻出血，是经气热所致。口唇生疮、颈部肿胀、喉痹、腹部肿胀、膝盖疼痛、胸胁股部及足背皆痛，是阳明经脉本身的病变。如果阳明经气盛于外，则身体前面发热；盛于内，则胃气有余而消化快易饥，小便黄。如果经气不足，则身体前面发冷颤抖，胃中有寒则胀满。经文说：三阳经作为经络，二阳经作为维系，一阳经作为游行出入的枢纽。大概阳明经气维系于身体前面，太阳经气行于身体后面，少阳经气是游行出入的枢纽。对于这些是动和所生的各种疾病，实证用泻法，虚证用补法，热证用疾刺法，寒证用留针法，阳气下陷用灸法，不虚不实则以本经取穴治疗。气生于阳明，而主宰于手太阴肺经。所以在手太阴和手足阳明经中讨论气的有余和不足，在其他各经只讨论是动和所生。尚御公说：手太阴经是动，则病肺胀膨膨然；足阳明经是动，则厌恶人与火，以及腹部雷鸣作响和腹胀，这是病气波及到经脉和脏腑。肺、胃、大肠所产生的疾病，表现为气的盛虚，这是病在脏腑经脉而影响到阴阳之气。大概三阴三阳之气，根本在于脏腑的五行生成，而外部配合于六经。
The Hand-Yangming Large Intestine Meridian has twenty acupoints. Its pathway starts from Shangyang (LI1), passes through Erjian (LI2) and Sanjian (LI3), reaches Hegu (LI4) and Yangxi (LI5), then passes through Pianli (LI6) and Wenliu (LI7), descends near Xialian (LI8), Shanglian (LI9), and Sanli (LI10), traverses the route of Quchi (LI11), Zhouliao (LI12), and Wuli (LI13), ascends to Binao (LI14) and Jianyu (LI15), and finally arrives at Jugu (LI16). Tianding (LI17) curves upward to Futu (LI18); Heliao (LI19) connects to the lips; Yingxiang (LI20) is close to the nose.
Shangyang (LI1) is located on the medial side of the index finger. Erjian (LI2) is sought in the depression before the proximal interphalangeal joint. Sanjian (LI3) is taken in the depression after the proximal interphalangeal joint. Hegu (LI4) is between the divergent bones of the web of the thumb and index finger. Yangxi (LI5) is on the radial side of the wrist crease. Pianli (LI6) is located three cun distal to the wrist crease. Wenliu (LI7) is five cun distal to the wrist crease. Xialian (LI8) is seen five cun proximal to Quchi (LI11). Shanglian (LI9) is three cun proximal to Quchi (LI11). Sanli (LI10) is encountered two cun proximal to Quchi (LI11). Quchi (LI11) is at the end of the transverse cubital crease when the elbow is flexed. Zhouliao (LI12) is near the lateral margin of the greater tubercle of the humerus. Wuli (LI13) is found by moving inward three cun above the elbow. Binao (LI14) is measured seven cun above the elbow. Jianyu (LI15) is taken at the shoulder tip with the arm raised. Jugu (LI16) is located superior to the shoulder tip. Tianding (LI17) is truly four cun lateral to the throat. Futu (LI18) is five cun lateral to Tiantu (CV22). Heliao (LI19) is five fen lateral to Shuigou (GV26). Yingxiang (LI20) is one cun superior to Heliao (LI19). The acupoints of the Large Intestine Meridian are clearly defined. (Forty acupoints in total, bilateral.)
The Foot-Yangming Stomach Meridian originates at the side of the nose, crossing at the root of the nose (Neiting/Sangen area), where it meets the Bladder Meridian laterally. It descends along the lateral aspect of the nose, enters the teeth, emerges to encircle the lips below, crosses at Chengjiang (CV24), then follows the posterior mandible downward, exits at Daying (ST5), follows Jiache (ST6), ascends anterior to the ear, passes through Guanchong/Shangguan (GB4), follows the hairline, and reaches the forehead. Its branch descends from the front of Daying (ST5) to Renying (ST9), follows the throat, enters the Supraclavicular Fossa (Quepen), passes through the diaphragm, belongs to the Stomach, and connects with the Spleen. Its main trunk descends from the Supraclavicular Fossa, follows the medial aspect of the breast, descends alongside the umbilicus, and enters the Qi Street (Qichong). Another branch originates from the stomach opening, descends along the abdominal interior, reaches the Qi Street to merge with the main trunk, then descends through Biguan (ST31), reaches Futu (ST32), descends into the patella, follows the lateral aspect of the tibia, descends to the dorsum of the foot, and enters the space between the second and third toes. Another branch separates three cun below the knee, descends to enter the lateral space of the second toe. Another branch separates from the dorsum of the foot, enters the space between the great toe, and emerges at its tip. When the meridian qi undergoes pathological changes, symptoms include shivering chills, frequent groaning, yawning, and darkening of the face. Upon onset, the patient dislikes people and fire, startles at the sound of wood, feels palpitations, and desires to stay alone behind closed doors and windows. In severe cases, they may climb high to sing, strip naked, and run. Abdominal rumbling and distension occur, known as Ben Tun Jue (Rebellious Qi Jue). This meridian primarily governs diseases generated by blood, such as mania, malaria, warm pathogenic disorders, sweating, rhinorrhea or epistaxis, ulcers on the lips, neck swelling, sore throat, edema of the large abdomen, pain and swelling of the knee and patella, pain along the chest, breast, Qi Street, thigh, Futu, lateral leg, and dorsum of the foot, and inability to use the second toe. Excess qi causes heat in the anterior body; excess in the Stomach leads to rapid digestion and hunger, and yellow urine. Deficient qi causes coldness and trembling in the anterior body; cold in the Stomach leads to distension. For these conditions: excess is treated with draining, deficiency with tonifying, heat with rapid needling, cold with retention of needles, sinking yang with moxibustion, and neither excess nor deficiency with selection from the meridian itself. In excess, the Renying pulse is three times larger than the Cunkou pulse; in deficiency, the Renying pulse is smaller than the Cunkou pulse. ("E" refers to the root of the nose; "Bi" refers to the thigh; "Bin" refers to the patella; "Fu" refers to the dorsum of the foot; "Ben" refers to running/rushing; "Dan" refers to abdominal distension; "Zhen" refers to sores/rashes.)
The sides of the nose are called "E". Below the cheeks is the "Han". The center of the chin is the "Yi". Above the cheeks is the hairline. Before the hairline is the forehead. The inner thigh is the "Bi". The muscular prominence anterior to the thigh above the knee is Futu. Posterior to Futu is Biguan. The area between the knee tendons is Bin. The tibia is "Xing". The dorsum of the foot is Fu. The Foot-Yangming Stomach Meridian receives connection from the Hand-Yangming Large Intestine Meridian, starting at Yingxiang (LI20) beside the nose, ascending and crossing at the root of the nose, passing Jingming (BL1), descending along the lateral nose, passing Chengqi (ST1), Sibai (ST2), and Juliao (ST3), entering the teeth, emerging to flank the mouth, passing Dicang (ST4) at the corners, encircling the lips, crossing at Chengjiang (CV24), following the posterior mandible, exiting Daying (ST5), following Jiache (ST6), ascending anterior to the ear, passing Xiaguan (ST7), Guanchong (GB4), following the hairline, passing Xuanli (GB5) and Hanyan (GB6), through Touwei (ST8), meeting at Shenting (GV24) on the forehead. Its branch descends from Daying (ST5) to Renying (ST9), follows the throat, passes Shuitu (ST10) and Qishe (ST11), enters the Supraclavicular Fossa, lateral to Yufu (KI27) of the Foot-Shaoyin Kidney Meridian, passes through the diaphragm at Zhongwan (CV12) and Xiaowan (CV10), belongs to the Stomach, and connects with the Spleen. The straight path descends from the Supraclavicular Fossa, follows the medial breast, passing Qihu (ST15), Kufang (ST16), Wuyi (ST17), Yingchuang (ST18), Ruzhong (ST18), Rugen (ST18), Burong (ST21), Chengman (ST22), Liangmen (ST23), Guanmen (ST24), Taiyi (ST25), Roubamen (ST26), flanking the umbilicus, passing Tianshu (ST25), Wailing (ST27), Daju (ST28), Shuidao (ST29), and Guilai (ST29), entering the Qi Street. Another branch originates from the Stomach, starts at the lower opening, follows the abdominal interior, lateral to Huangshu (KI12) of the Foot-Shaoyin Kidney Meridian, within the interior of this meridian, descends to the Qi Street to merge with the previous branch. After merging at the Qi Street, it descends through Biguan (ST31), reaches Futu (ST32), passes Yinshi (ST33) and Liangqiu (ST34), enters the patella, passes Dubi (ST35), descends along the foot dorsum to Chongyang (ST42), Xangu (ST43), enters the medial space of the second toe to Neiting (ST44), ending at Lidui (ST45). The collateral branch separates three cun below the knee, lateral to Zusanli (ST36), descends passing Shanglian (ST37), Tiaokou (ST38), Xialian (ST39), Fenglong (ST40), Jiexi (ST41), Chongyang (ST42), Xangu (ST43), to merge at Neiting (ST44) and Lidui (ST45). Another branch separates from Chongyang (ST42) on the dorsum, enters the great toe space, exits lateral to Xingjian (LR2) of the Foot-Jueyin Liver Meridian, follows the great toe to its tip, connecting with the Foot-Taiyin Spleen Meridian. Pathological changes in Yangming qi cause shivering chills because Yangming corresponds to Wu (noon), where extreme Yang is met by Yin, causing chills. Groaning indicates stagnant Yang seeking release. Yawning indicates Yang seeking to rise. Darkening of the face indicates Yin affecting the upper body. These are signs of Yangming qi pathology. When disease qi reaches the meridian, Yangming meridian disease causes aversion to people and fire, and startling at wood sounds. Since the Stomach channel connects to the Heart, palpitations occur. Yin-Yang struggle causes desire for isolation. Extreme Yang leads to solid limbs, climbing high, singing, stripping, and running due to internal heat. The Yangming meridian passes through the diaphragm, belongs to the Stomach, and connects with the Spleen, causing abdominal rumbling and distension. This is rebellious Qi in the meridian causing these symptoms, hence termed Ben Tun Jue. The Yangming meridian descends along the lateral tibia. Diseases may affect qi without reaching the meridian, show meridian symptoms while rooted in qi, involve mixed meridian and qi pathology, or transition from qi to meridian; thus, they can be analyzed separately or together. The Classic states: Food enters the Stomach, meridians open, and blood qi flows. The Ping Mai Pian states: Water enters the meridians, and blood forms. The Stomach is the Sea of Grain and Water, generating Ying Blood; thus, it governs blood-related diseases like mania, warm malaria, and sweating (due to Stomach heat evaporating fluids). Rhinorrhea/epistaxis is due to meridian heat. Lip ulcers, neck swelling, sore throat, abdominal edema, knee pain, and pain in the chest, thigh, and dorsum are direct meridian diseases. Excess external qi causes anterior heat; excess internal qi causes hunger and yellow urine. Deficient qi causes anterior cold and Stomach cold distension. The Classic says: Three Yang are the channels, Two Yang are the maintenance, One Yang is the pivot. Yangming maintains the anterior body, Taiyang conducts the posterior body, Shaoyang is the pivot of movement. For these Is Dong and Suo Sheng diseases: excess drains, deficiency tonifies, heat uses rapid needling, cold retains needles, sinking uses moxibustion, neutral selects from the meridian. Qi originates in Yangming but is governed by Hand-Taiyin Lung. Thus, discussions on excess/deficiency of Qi focus on Hand-Taiyin and Hand/Foot-Yangming, while other meridians discuss only Is Dong and Suo Sheng. Shang Yugong stated: Hand-Taiyin Is Dong causes lung distension; Foot-Yangming Is Dong causes aversion to people/fire and abdominal rumbling/distension, indicating disease qi affecting meridians and organs. Diseases of Lung, Stomach, and Large Intestine manifest as Qi excess/deficiency, meaning organ/meridian disease affects Yin-Yang Qi. The Three Yin and Three Yang Qi originate from the Five Elements of the Zang-Fu and externally correspond to the Six Channels.
