手太阳小肠经的经脉，起始于小指末端（小指末端是少泽穴所在之处），沿着手的尺侧边缘前行（在手外侧，掌指关节之前，是前谷穴；掌指关节之后，是后溪穴），向上到达手腕（腕部前方为腕骨，后方为阳骨），从尺骨茎突处穿出，直上沿前臂尺骨下缘，经过肘部内侧两骨之间（肘内侧两骨之间有小海穴），继续上行沿上臂外侧后缘，出于肩关节后方，进入腋窝，绕行肩胛部，交会于肩上，进入缺盆，联络心脏（心是小肠的维系所在，所以小肠经脉络于心），沿着咽喉向下穿过膈肌，到达胃部，属于小肠（手太阳经是小肠的经脉，所以其脉归属于小肠）。它的分支，从缺盆沿着颈部上达面颊，至目外眦（《针经》说：面部外侧眼角称为锐眦），折回进入耳中。另一分支，从面颊部分出，上行至颧骨，抵达鼻旁，至目内眦（手太阳经至此与足太阳膀胱经交接），斜行络于颧骨（颧骨即面颊骨）。
当本经发生病变时（手太阳经通常多血少气，若气先发病，称为“是动病”），会出现咽喉疼痛、下颌肿胀（下颌指下巴下方），不能回顾转头，肩部感觉像被拔除一样，肘部感觉像折断一样。本经主要主管津液，所发生的病症（血液受气的影响，气能生血，故称“所生病”）包括耳聋、目黄、面颊和下颌肿胀、颈项、肩、肘、臂外侧后缘疼痛。实证表现为人迎脉搏动比寸口脉大二倍，虚证则人迎脉反而小于寸口脉。
手太阳经的别络，名叫支正，在腕后五寸处，向内注入手少阴心经。其分支，上行走向肘部，络于肩部。实证表现为关节弛缓、肘部废用；虚证则生疣赘，小的如手指甲上的痂疥。治疗都取该别络穴。
手太阳经的筋，起始于小指上方，结聚于腕上，沿前臂内侧边缘结聚于肘部内侧锐骨之后，弹拨时感应传至小指上方，结聚于腋下。其分支，向后行走于腋后缘，上行绕过肩胛，沿头部出于足太阳膀胱经之前，结聚于耳后完骨。其另一分支，进入耳中，直出耳上，下行结聚于下颌上方，联系目外眦。这类病症表现为小指及肘部内侧锐骨后缘疼痛，手臂内侧入腋下疼痛，腋后缘疼痛，绕肩胛牵引颈部疼痛，应和耳中鸣痛牵引下颌，眼睛闭合良久才能视物。头颈部筋脉拘急则为筋痿，颈部肿胀伴寒热。病在颈部的，治疗用燔针劫刺法；若有肿块，用温熨并磨尖针具刺破。本经分支上行至曲牙穴，沿耳前联系目外眦，上行至额角结聚。这类病症表现为循行部位出现支撑性转筋，治疗用燔针劫刺，以见效为度，以痛点为腧穴。这种病名叫“仲夏痹”。
小肠发生病变，表现为小腹部疼痛，腰脊牵引睾丸而痛，时常窘迫欲大便，耳前感觉特别寒冷，只有肩部发热以及小指和次指之间发热。如果脉象陷下不起，这是小肠病的征候。
邪气在小肠，连系睾丸，附着于脊柱，贯穿肝肺，络属心系。气盛则气逆上冲，肠胃蠕动，肝肺之气散于肓膜，结聚于脐部。因此取肓原穴以消散邪气，刺手太阴肺经以补益正气，取手厥阴心包经以降逆气，取巨虚上廉和巨虚下廉以祛除邪气，控制其循行经过的部位，通过经络来调理气血。
手太阳小肠经，从手走头，长度五尺，左右共一丈。共有三十八个穴位。
少泽二穴，前谷二穴，后溪二穴，腕骨二穴，阳谷二穴，养老二穴，支正二穴，小海二穴，肩贞二穴，天宗二穴，秉风二穴，曲垣二穴，肩外俞二穴，肩中俞二穴，天窗二穴，天容二穴，颧髎二穴，听宫二穴。
The meridian of Hand-Taiyang [Shou Taiyang Jing] originates at the tip of the little finger (where Shaose [SI 1, Little Sea] is located). It follows the ulnar side of the hand (Qian Gu [SI 2, Front Valley] is anterior to the metacarpophalangeal joint on the ulnar side; Hou Xi [SI 3, Rear Stream] is posterior to it). It ascends to the wrist (Wangu [Ulnar Styloid Process] anteriorly and Yanggu [Radial Styloid Process] posteriorly), emerges from the styloid process of the ulna, goes straight up along the lower border of the ulna, emerges between the two bones on the medial side of the elbow (Xiaohai [SI 8, Little Sea] is located between the two bones of the medial elbow). It continues upward along the posterior lateral border of the upper arm, emerges from the posterior aspect of the shoulder joint, enters the axilla, winds around the scapula, crosses the shoulders, enters the supraclavicular fossa (Quepen), and connects with the Heart (The Heart is the anchor of the Small Intestine, thus the Small Intestine meridian links to the Heart). It follows the throat, descends through the diaphragm, reaches the Stomach, and belongs to the Small Intestine (Hand-Taiyang is the meridian of the Small Intestine, hence its pulse belongs to the Small Intestine). Its branch arises from the supraclavicular fossa, pierces the neck, ascends to the cheek, and reaches the outer canthus of the eye (The *Classic of Acupuncture* states: the outer corner of the eye on the face is called the 'Rui' or sharp point). It then re-enters the ear. Another branch separates from the cheek, ascends to the zygomatic bone, reaches the nose, and arrives at the inner canthus of the eye (Hand-Taiyang intersects with Foot-Taiyang here). It obliquely connects with the zygomatic bone (Zygoma refers to the cheekbone).
When this meridian is disturbed ("Shi Dong" disease, meaning the Qi is diseased first, as Hand-Taiyang typically has abundant Blood and scarce Qi), symptoms include sore throat and swelling of the mandible (Mandible refers to the area below the chin), inability to look back, a sensation that the shoulder is being pulled out, and a sensation that the elbow is broken. This meridian primarily governs fluids. Diseases generated by it ("Suo Sheng Bing", meaning diseases generated by Qi which generates Blood) include deafness, yellowing of the eyes, swelling of the cheeks and mandible, and pain along the posterior lateral border of the neck, shoulder, elbow, and arm. In excess conditions, the Renying [ST 9, Human Well] pulse is twice as strong as the Cunkou [Radial Artery] pulse. In deficiency conditions, the Renying pulse is weaker than the Cunkou pulse.
The Luo-connecting vessel of Hand-Taiyang is named Zhizheng [SI 7, Branching Correct]. It is located five cun above the wrist, connecting inwardly to Hand-Shaoyin. Its branch ascends to the elbow and connects with the shoulder. In excess, there is flaccidity of the joints and uselessness of the elbow. In deficiency, warts appear, small ones resembling scabs or ringworm on the fingers. Treatment involves needling the Luo-connecting point.
The sinews of Hand-Taiyang originate above the little finger, knot at the wrist, follow the medial border of the forearm, and knot behind the medial epicondyle of the humerus. Palpation transmits sensation to the little finger. They knot in the axilla. A branch travels posteriorly along the posterior axillary fold, ascends around the scapula, follows the head emerging anterior to Foot-Taiyang, and knots at the Occiput [Wangu, GB 12]. Another branch enters the ear, exits superiorly from the ear, and knots inferiorly above the mandible, connecting to the outer canthus. Symptoms include pain along the little finger, posterior medial border of the elbow, medial arm entering the axilla, axillary pain, posterior axillary fold pain radiating to the neck, tinnitus and pain in the ear radiating to the mandible, temporary blindness requiring time to recover vision. Spasm of cervical sinews leads to Sinew Atrophy. Neck swelling with chills and fever in the neck region is treated with burning needle (Cuan Zhen) and rapid puncture (Jie Ci). For swellings, apply heat and use an acute needle. The branch ascending to Quya [ST 7, Jaw Bone], following the anterior ear to the outer canthus, and knotting at the forehead angle, presents with spasmodic contraction along its pathway. Treatment is burning needle and rapid puncture, repeated until efficacy is achieved, using the painful point as the acupoint. This condition is named "Zhongxia Bi" [Midsummer Obstruction].
Diseases of the Small Intestine manifest as lower abdominal pain, pain radiating from the waist and spine to the testicles, frequent urgency for defecation, cold sensation in front of the ears, isolated heat in the shoulder, and heat between the little finger and the ring finger. If the pulse is sunken, these are signs of Small Intestine disease.
Pathogenic factors in the Small Intestine connect to the testicular ligaments, attach to the spine, penetrate the Liver and Lung, and link to the Heart system. Excess Qi causes rebellious Qi rushing upward, intestinal motility, and dispersion of Liver and Lung Qi into the Huang [Blind Area/Mesentery], knotting at the umbilicus. Therefore, treat Huangyuan [CV 12, Center of the Abdomen] to dissipate it. Puncture Hand-Taiyin [Lung Meridian] to tonify it. Take Hand-Jueyin [Pericardium Meridian] to descend it. Take Juxu Shanglian [ST 37, Upper Great Void] and Juxu Xialian [ST 39, Lower Great Void] to remove it. Control the affected pathways and regulate via the meridians.
The Hand-Taiyang meridian runs from the hand to the head, measuring five chi in length, totaling one zhang for both sides. There are thirty-eight acupoints in total.
