手阳明大肠经的经脉，起始于食指末端。沿着食指桡侧上行，出于合谷穴位于第一、二掌骨之间。向上进入两筋（拇长伸肌腱与拇短伸肌腱）之中。沿前臂桡侧上行，进入肘部外侧，沿上臂外侧前缘上行。经过肩部，出于肩峰前缘上方，向下进入缺盆（锁骨上窝）。联络肺脏，向下穿过膈肌，归属于大肠。其支脉，从缺盆上行至颈部，贯穿面颊，进入下齿龈中。复出，环绕口唇，在人中穴处交叉：左侧的经脉走向右侧，右侧的经脉走向左侧。上行夹持鼻孔两侧，终于迎香穴。本经共有二十个穴位，此处选取七个穴位进行介绍。

The meridian of the Hand-Yangming Large Intestine originates at the tip of the index finger. It follows the radial side of the finger, emerges between the two bones at Hegu (LI4), and ascends into the space between the two tendons. It then follows the radial aspect of the forearm, enters the lateral aspect of the elbow, and ascends along the anterior border of the lateral aspect of the upper arm. It passes through the shoulder, emerges anterior to the acromion process, descends into the Supraclavicular Fossa (Quepen, ST12), connects with the Lung, descends through the Diaphragm, and belongs to the Large Intestine. Its branch arises from the Supraclavicular Fossa, ascends to the neck, penetrates the cheek, and enters the lower teeth. It returns to emerge, surrounds the lips, crosses at the Philtrum (Renzhong, GV26) where the left meridian turns to the right and the right to the left, ascends flanking the nostrils, and terminates at Yingxiang (LI20). There are twenty acupoints in total on this meridian; here, seven points are selected for description.
Shangyang (SI1, also known as Jueyang): Located on the radial side of the index finger, approximately the width of a leek leaf from the corner of the nail. This is the Jing-Well point (Jing-well point: the point where the Qi emerges) of the Hand-Yangming Large Intestine Meridian. Puncture depth: 1 fen; retain needle for one exhalation; moxibustion: 3 cones. Indications: Chest fullness, asthma, cough, dry mouth, swelling of the jaw, toothache, blindness. *Qiankun Shengyi* states: This point belongs to the Ten Jing-Well points. In cases of sudden stroke, fall, coma, locked jaw, sore throat, or inability to swallow medicine, urgently puncture this point with a three-edged needle, as well as Shaoshang (LU11), Zhongchong (PC9), and Shaochong (HT9), to promote the flow of Qi and Blood. This is a wonderful method for emergency resuscitation.
Hegu (LI4, also known as Hukou): Located in the depression between the first and second metacarpal bones. This is the Yuan-Source point (Yuan-source point: the point where the Source Qi passes) of the Hand-Yangming Large Intestine Meridian. Puncture depth: 3 fen; retain needle for six exhalations; moxibustion: 3 cones. Indications: Headache, stiffness of the spine, facial swelling, corneal opacity, fever with aversion to cold, trismus (locked jaw), throat obstruction, tonsillitis. Another view holds that it can expel a dead fetus. For pregnant women, tonifying Hegu may cause abortion. *Qianjin Fang* records: If the pulse becomes imperceptible after childbirth, puncture Hegu, insert 3 fen, and urgently apply the tonifying method. *Baizheng Fu* records: Combined with Tianfu (LU3), it treats epistaxis (nosebleed). Ma Danyang’s *Tianxing Twelve Points* records: Treats headache and facial swelling, dental caries with nosebleed, trismus preventing speech. Puncture depth: 5 fen; it brings peace to the patient.
Yangxi (LI5, also known as Zhongkui): Located in the depression between the two tendons on the radial side of the wrist crease. This is the Jing-River point (Jing-river point: the point where the Qi flows like a river) of the Hand-Yangming Large Intestine Meridian. Puncture depth: 3 fen; retain needle for seven exhalations; moxibustion: 3 cones. Indications: Manic speech, laughter, hallucinations, heat diseases with vexation, throat obstruction, tinnitus, toothache, red eyes, purulent corneal opacity, chills and fever, phlegm-malaria. *Xi Hong Fu* records: Combined with Erjian (LI2), it treats toothache and throat bi-syndrome.
Shousanli (LI10): Located 2 cun below Quchi (LI11), at the end of the raised muscle belly, which rises upon pressure. Puncture depth: 3 fen; moxibustion: 3 cones. Indications: Toothache,烦热 (vexatious heat) and swelling, scrofula, numbness and lack of sensation in the hand.
Quchi (LI11): Located in the depression at the lateral end of the elbow crease when the elbow is flexed. To locate it, place the hand against the chest. This is the He-Sea point (He-sea point: the point where the Qi enters deeply) of the Hand-Yangming Large Intestine Meridian. Puncture depth: 7 fen; retain needle for seven exhalations; moxibustion: 3 cones (another view suggests 100 cones). Indications: Redness and swelling of the arm, elbow pain, hemiplegia due to wind-stroke, dry skin with scabies, amenorrhea. Ma Danyang’s *Tianxing Twelve Points* records: Effectively treats elbow pain, hemiplegia with inability to retract the hand, weakness preventing drawing a bow or combing hair, severe throat obstruction resembling death, persistent fever, and generalized prurigo/lichen. Puncture leads to immediate recovery. *Xi Hong Fu* records: Combined with Hegu (LI4), it treats dysfunction of the hand.
Wuli (LI13): Located 3 cun above the elbow, in the center of the large artery running inward. Another view places it 5 cun below Tianfu (LU3). Puncture is contraindicated. Moxibustion: 3 cones (another view suggests 10 cones). Indications: Pain in the elbow and arm making movement difficult, chills and fever, scrofula.
Jugu (LI14): Located in the depression between the two bones above the shoulder tip. It is the intersection of the Hand-Yangming Large Intestine Meridian and the Yangqiao Vessel. Puncture depth: 6 fen; moxibustion: 3 or 5 cones (another view suggests puncture is contraindicated). Indications: Convulsions, epilepsy, hemoptysis, blood stasis in the chest, arm pain with inability to extend or flex.
