十二经脉包括手三阳经、手三阴经、足三阳经和足三阴经，合称为十二经脉。《灵枢》中提到：“节之交三百六十五会”，所说的“节”，是指神气游行出入的地方，并非指皮、肉、筋、骨。又说：“神气”即正气，神气游行出入的过程就是流注；井穴、荥穴、输穴、经穴、合穴，也就是本输穴。（出自《灵枢》）十二经脉原本是一脉，只是大致分为十二个部分而已。（出自李东垣）
手太阴肺经的经脉，起始于中焦（中府穴），向下联络大肠，环绕胃的上口，穿过膈肌，属于肺脏；从肺系（气管、喉咙等与肺相连的组织）横行出于腋下（天府穴），向下沿上臂内侧前缘（肩下臂上通名曰臑），走在手少阴心经和手厥阴心包经的前面，下行至肘窝中（臂上下缓处叫作肘，即尺泽穴）；沿前臂内侧（前臂下有掌上的骨头叫作臂，臂有两根骨头），上行至桡骨茎突内侧边缘，进入寸口（经渠穴、太渊穴）；经过大鱼际部，沿着鱼际边缘（鱼际穴），出于大拇指末端（少商穴）。
其支脉（列缺穴），从腕后直出，行至食指内侧边缘，出于其末端（交入手阳明大肠经）。
这条经脉发生异常变动时，会出现肺胀满，膨膨然气喘咳嗽，缺盆中疼痛；严重时甚至两手交叉按于胸前而视物模糊，这叫做臂厥。
本经主治肺脏所生的疾病：咳嗽，气喘，呼吸有声，心烦胸满，上臂内侧前缘疼痛，厥冷，掌心发热。
实证表现为肩背疼痛怕风，风寒汗出，中风，小便频数且打哈欠；虚证表现为肩背痛怕冷，气短不足以息。
实证时，寸口脉比人迎脉大三倍；虚证时，寸口脉反而小于人迎脉。（出自《灵枢》）每天早晨寅时，气血从中府穴开始，沿手臂下行，至少商穴停止。（出自《医学入门》）
少商穴有两个，位于手大拇指尖端内侧，距离指甲角如韭菜叶宽处，是手太阴肺经的井穴，为经气所出之处。针刺深度一分，留针三呼的时间，采用泻法（吸气五次时进针或行针）。禁止艾灸。（出自《铜人腧穴针灸图经》）出血可以泻除各脏腑的热邪。（出自《灵枢》）用三棱针浅刺使其微出血，以泄诸脏之热凑。咽喉肿痛堵塞，水谷不能吞咽，针刺此穴可立即痊愈。（出自《资生经》）
鱼际穴有两个，位于手大拇指本节后的内侧散脉中，是手太阴肺经的荥穴，为经气所流之处。针刺深度二分，留针三呼的时间。禁止艾灸。（出自《医学入门》）
太渊穴有两个，又名太泉，位于手掌后横纹头凹陷中。一说在鱼际穴后一寸的凹陷中，是手太阴肺经的输穴，为经气所注之处。针刺深度二分，可灸三壮。（出自《铜人腧穴针灸图经》）
经渠穴有两个，位于寸口脉动处，是手太阴肺经的经穴，为经气所行之道。针刺深度二分，留针三呼的时间。禁止艾灸，若灸则损伤人的神气。（出自《铜人腧穴针灸图经》）
列缺穴有两个，位于手腕侧上一寸五分处。取穴方法为双手交叉，中指指尖所在的两骨缝隙中。此为手太阴肺经的络穴，走向手阳明大肠经。针刺深度二分，留针三呼的时间，采用泻法（吸气五次时进针或行针），可灸七壮。（出自《资生经》）
孔最穴有两个，位于手腕侧面往上七寸的宛宛凹陷中，是手太阴肺经的郄穴。针刺深度三分，可灸五壮。（出自《铜人腧穴针灸图经》）
尺泽穴有两个，位于肘窝横纹中。（出自《铜人腧穴针灸图经》）○是肘中的动脉。又说是肘中横纹上的动脉中。（出自《纲目》）○位于手臂屈伸时的横纹中，筋骨之间的凹陷处。又说是肘中横纹上两筋之间的动脉中。（出自《资生经》）○是手太阴肺经的合穴，为经气所入之处。针刺深度三分，可灸五壮。（出自《铜人腧穴针灸图经》）另一说认为不宜艾灸。（出自《医学入门》）
侠白穴有两个，位于天府穴下方，肘上五寸的动脉中。针刺深度三分，可灸五壮。（出自《铜人腧穴针灸图经》）
天府穴有两个，位于腋下三寸，腋臂内侧廉的动脉中。取穴方法是举起手臂，以鼻尖对准穴位定位。针刺深度三分，留针三呼的时间。禁止艾灸。（出自《铜人腧穴针灸图经》）
云门穴有两个，位于巨骨穴下方，挟气户穴旁开二寸的凹陷中，按压有动脉应手。取穴方法是举起手臂。针刺深度三分，可灸五壮。刺得太深会导致气逆，所以不宜深刺。（出自《甲乙经》）○在人迎穴下方的第二肋骨间，相距二寸四分。（出自《资生经》）
中府穴有两个，是肺的幕府，又名膺中俞。位于云门穴下一寸的凹陷中，乳头上三肋间，按压有动脉应手。取穴方法是仰卧位。此为手太阴肺经和手阳明大肠经的交会穴。针刺深度三分，留针三呼的时间，可灸五壮。（出自《铜人腧穴针灸图经》）
The twelve meridians consist of the three Yang meridians of the hand, the three Yin meridians of the hand, the three Yang meridians of the foot, and the three Yin meridians of the foot, collectively known as the Twelve Meridians. The *Ling Shu* (Spiritual Pivot) states: "At the junctions of the joints, there are 365 acupoints." The term "joint" here refers to the places where Shen Qi (Vital Energy and Spirit) travels in and out, not referring to skin, flesh, sinews, or bones. It is further stated that "Shen Qi" is Zheng Qi (Upright/Healthy Qi). The process of Shen Qi traveling in and out is called Liu Zhu (Flowing and Pouring); the Jing-Well, Ying-Spring, Shu-Stream, Jing-River, and He-Sea points are also known as Ben Shu (Original Transport) points. (From *Ling Shu*) The Twelve Meridians originally constitute one continuous pathway, merely divided into twelve segments for description. (From Li Dongyuan)
The meridian of Hand-Taiyin Lung originates from the Middle Jiao (Zhongfu LU-1), descends to connect with the Large Intestine, circles around the upper opening of the Stomach, pierces through the Diaphragm, and belongs to the Lung. From the Lung system (trachea, larynx, etc., tissues connected to the lung), it emerges horizontally from under the axilla (Tianfu LU-3), descends along the anterior aspect of the medial side of the upper arm (the area between the shoulder and elbow is generally called Nao), running anterior to the Heart-Shaoyin and Pericardium-Jueyin meridians. It descends into the cubital fossa (the relaxed area at the elbow is called Zhou, i.e., Chize LU-5), follows the medial aspect of the forearm (the bone below the elbow leading to the palm is called Bi; the forearm has two bones), ascends along the lower edge of the radius, enters the Cun Kou (pulse position at the wrist, containing Jingqu LU-8 and Taiyuan LU-9), passes over the Thenar eminence, follows the radial border of the thenar eminence (Yuji LU-10), and emerges at the tip of the thumb (Shaoshang LU-11).
Its branch (Lieque LU-7) arises from behind the wrist, goes straight out to the medial side of the index finger, and emerges at its tip (connecting to the Hand-Yangming Large Intestine meridian).
When this meridian undergoes pathological changes, it causes Lung distension, fullness, bloating, wheezing, and coughing; pain in the Supraclavicular Fossa (Quepen). In severe cases, the patient may cross both hands over the chest and experience visual disturbance (Mao); this is termed Bi Jue (Arm Jue syndrome).
This meridian governs diseases generated by the Lung: cough, asthma, panting, irritability, chest fullness, pain along the anterior medial aspect of the upper arm, coldness/jue sensation, and heat in the palm.
Excess patterns manifest as shoulder and back pain, aversion to wind, sweating due to wind-stroke, frequent urination, and yawning. Deficiency patterns manifest as shoulder and back pain, coldness, shortness of breath, and inability to breathe deeply.
In excess conditions, the Cun Kou pulse is three times larger than the Renying pulse. In deficiency conditions, the Cun Kou pulse is smaller than the Renying pulse. (From *Ling Shu*) Every morning during the Yin hour (03:00–05:00), Qi starts from Zhongfu LU-1, flows down the arm, and stops at Shaoshang LU-11. (From *Yixue Rumen*)
Shaoshang (LU-11): Two points located at the radial side of the tip of the thumb, approximately the width of a leek leaf from the corner of the nail. This is the Jing-Well point of the Hand-Taiyin Lung meridian, where Qi emerges. Needle depth: 1 fen; retain for 3 breaths; use reducing method (insert during expiration or manipulate during inhalation for 5 cycles). Moxibustion is prohibited. (From *Tongren*) Bleeding can drain heat from all Zang organs. (From *Ling Shu*) Puncture with a three-edged needle to induce slight bleeding to drain heat accumulating in the Zang organs. For throat swelling and obstruction preventing swallowing of water or food, needling this point brings immediate relief. (From *Zisheng*)
Yuji (LU-10): Two points located on the medial side of the thenar eminence, just distal to the first metacarpophalangeal joint, within the scattered vessels. This is the Ying-Spring point of the Hand-Taiyin Lung meridian, where Qi flows. Needle depth: 2 fen; retain for 3 breaths. Moxibustion is prohibited. (From *Yixue Rumen*)
Taiyuan (LU-9): Two points, also named Taiquan, located in the depression at the proximal end of the transverse crease of the wrist. Another view places it 1 cun distal to Yuji in the depression. This is the Shu-Stream point of the Hand-Taiyin Lung meridian, where Qi pours in. Needle depth: 2 fen; moxibustion: 3 moxa cones. (From *Tongren*)
Jingqu (LU-8): Two points located at the Cun Kou pulse position. This is the Jing-River point of the Hand-Taiyin Lung meridian, where Qi travels. Needle depth: 2 fen; retain for 3 breaths. Moxibustion is prohibited, as it damages the person's Shen (Spirit). (From *Tongren*)
Lieque (LU-7): Two points located 1.5 cun above the wrist crease on the radial side. To locate, cross the hands; the point lies in the gap between the two bones where the tip of the middle finger rests. This is the Luo-Connecting point of the Hand-Taiyin Lung meridian, which connects to the Hand-Yangming Large Intestine meridian. Needle depth: 2 fen; retain for 3 breaths; use reducing method (manipulate during inhalation for 5 cycles); moxibustion: 7 moxa cones. (From *Zisheng*)
Kongzui (LU-6): Two points located 7 cun above the wrist crease on the radial side, in the hollow depression. This is the Xi-Cleft point of the Hand-Taiyin Lung meridian. Needle depth: 3 fen; moxibustion: 5 moxa cones. (From *Tongren*)
Chize (LU-5): Two points located in the center of the cubital crease. (From *Tongren*) ○ It is the arterial pulse in the elbow. Another view says it is in the arterial pulse on the cubital crease. (From *Gangmu*) ○ Located in the transverse crease when flexing and extending the arm, in the depression between the sinews and bones. Another view says it is in the arterial pulse between the two sinews above the cubital crease. (From *Zisheng*) ○ It is the He-Sea point of the Hand-Taiyin Lung meridian, where Qi enters. Needle depth: 3 fen; moxibustion: 5 moxa cones. (From *Tongren*) Another view states it should not be moxibusted. (From *Yixue Rumen*)
Xiabai (LU-2): Two points located below Tianfu LU-3, 5 cun above the elbow, in the arterial pulse. Needle depth: 3 fen; moxibustion: 5 moxa cones. (From *Tongren*)
Tianfu (LU-3): Two points located 3 cun below the axilla, in the arterial pulse on the medial aspect of the arm. To locate, raise the arm and align with the tip of the nose. Needle depth: 3 fen; retain for 3 breaths. Moxibustion is prohibited. (From *Tongren*)
Yunmen (LU-2): Two points located below the Jugu bone (clavicle/acromion area), 2 cun lateral to Qihu (ST-14), in the depression where an arterial pulse is palpable. To locate, raise the arm. Needle depth: 3 fen; moxibustion: 5 moxa cones. Do not needle too deeply, as it may cause Qi rebellion; therefore, deep insertion is unsuitable. (From *Jia Yi Jing*) ○ Located in the second intercostal space below Renying (ST-9), 2.4 cun apart. (From *Zisheng*)
Zhongfu (LU-1): Two points, the "curtain" of the Lung, also named Yingzhongshu. Located 1 cun below Yunmen LU-2, in the depression, in the third intercostal space above the nipple, where an arterial pulse is palpable. To locate, lie supine. This is the meeting point of the Hand-Taiyin Lung and Hand-Yangming Large Intestine meridians. Needle depth: 3 fen; retain for 3 breaths; moxibustion: 5 moxa cones. (From *Tongren*)
