证治 烦心善哕。心下满。汗出而寒。咳逆。 疟振寒。腹满唾沫。唇干引饮不下。膨
膨。手挛指痛。寒栗鼓颔。喉中鸣。
针灸 三棱针刺之。微出血。泄诸脏热气。不宜灸。
按 少商乃阴井木穴之始。西方白色。入通于肺。其音商。商而曰少者。五脏为阴。
阴常不足也。
二、鱼际（荥穴）

目眩烦心。少气。腹痛不下食。肘挛支满。喉中干燥。寒栗鼓颔。咳引尻痛。溺出。呕血。心痹。悲恐。
针灸 针入二分。留三呼。
按∶鱼际乃阴荥火穴。在手大指后鱼腹中。手大指接近次指时。则鱼腹丰满。离开次
指时。则本节后内侧微陷下。有如鱼腹正中交际之形。故名鱼际。鱼际为火穴。
肺为金藏。火能克金。故此穴言针不言灸。
三、大渊（俞穴）

按∶大渊乃脉之所会。本输篇云。鱼后一寸陷者中也。为俞。盖其穴在手大指如鱼形
之后。再下一寸。即寸口脉之起点。此五脏之 穴。亦称原穴。盖六腑水谷精华。
注入五脏经 之起原处。故称渊。
四、经渠（经穴）

暴痹喘。足心痛。呕吐。
针灸 针入二分。留三呼。禁不可灸。灸即伤人神。
按∶经渠寸口中也。动而不居。即关上部位。寸至关长一寸九分。以下即为尺中。言
经渠者。乃经过之冲渠要道。大渊在寸口之始。经渠居寸口之中。并未入于尺中也。

者针之。泻某子故也。肺乃脏气之藏。山泽通气。此穴恰在太阴尺中。脉之结点。
故名尺泽。义至深也。
一、少商（井穴）
部位：位于手大拇指尖端内侧。距离指甲角约如韭菜叶宽度处。
证治：心烦，易呃逆。心窝部胀满。出汗且怕冷。气逆咳嗽。疟疾发冷战栗。腹部胀满，口吐涎沫。嘴唇干燥想喝水但咽不下去。腹部膨隆。手部痉挛，手指疼痛。寒战咬牙。喉中发出鸣响。
针灸：用三棱针点刺，使其微微出血，以泄除各脏腑的热气。不宜使用艾灸。
按语：少商是阴经井穴（木穴）的起始穴。西方对应白色，内通于肺。其音为商。称为“少”，是因为五脏属阴，而阴气常显不足。
二、鱼际（荥穴）
部位：在大拇指本节（第一掌指关节）后方的散在血脉中。
证治：洒淅恶风寒。虚热。舌苔黄。身体发热头痛。咳嗽。无汗。痹症游走至胸背部疼痛。呼吸困难。头晕目眩，心烦。气短。腹痛，不能进食。肘部挛急，支撑感导致胀满。喉咙干燥。寒战咬牙。咳嗽牵引尾骨痛。小便失禁。呕血。心痹。悲伤恐惧。
针灸：进针二分，留针三个呼吸的时间。
按语：鱼际是阴经荥穴（火穴）。位于大拇指后方鱼腹状肌肉中。当大拇指靠近食指时，该处鱼腹丰满；离开食指时，本节后方内侧微陷下，形状如同鱼腹正中交汇之处，因此得名鱼际。鱼际为火穴，肺为金脏，火能克金，所以此穴只言针刺而言不灸。
三、太渊（俞穴/原穴）
部位：在手掌后方的凹陷中。
证治：胸痹气逆。寒厥易呃逆呕吐。饮水后咳嗽。烦闷无法安卧。肺部胀满膨隆。手臂内侧疼痛。眼睛生白翳。眼结膜充血血管怒张。缺盆中牵引疼痛。掌心发热。频繁打哈欠。气喘呼吸困难。嗳气上逆。心痛唾血。发冷战栗。咽喉干燥。胡言乱语，口眼歪斜。
针灸：进针二分，可灸三壮。
按语：太渊是脉气汇聚之处。《本输》篇说：“鱼际后一寸凹陷处。”即为俞穴。大概位于手大拇指如鱼形之后，再向下一寸，正是寸口脉的起点。这是五脏的腧穴，也称为原穴。因为六腑水谷的精华，注入五脏经脉的起始源头处，所以称为渊。
四、经渠（经穴）
部位：在寸口处的凹陷中。
证治：疟疾寒热往来。胸背部拘急。胸部胀满膨隆。喉痹。掌心发热。咳嗽气逆。频繁打哈欠。热病无汗。突发痹症气喘。足心疼痛。呕吐。
针灸：进针二分，留针三个呼吸的时间。禁止艾灸，艾灸会损伤人体神气。
按语：经渠位于寸口中，脉动而不居，即关部的部位。从寸到关长一寸九分，以下即为尺部。称其为经渠，是经过的冲要渠道。太渊在寸口的起始处，经渠居于寸口的中部，并未进入尺部之中。
五、尺泽（合穴）
部位：在肘横纹中央的动脉搏动处。
证治：风痹肘部挛急。手臂不能举起。喉痹气逆。舌干。咳嗽吐浊痰。四肢突然肿胀。手臂寒冷气短。
针灸：进针三分，可灸五壮。
按语：尺泽是肺经的合穴，既可针刺，也可艾灸。因为阴经的合穴属水，肺为金脏，水乃金之所生（金生水）。邪气实盛者用针刺，是为了泻其子（水为金之子），故曰泻其子。肺是脏气的藏所，山泽通气。此穴恰好在太阴经的尺部，是脉气的结点，所以名叫尺泽，含义非常深远。
1. Shaoshang (Jing-Well Point)
Location: On the radial side of the tip of the thumb, approximately the width of a leek leaf from the corner of the nail.
Indications and Treatments: Restlessness, frequent hiccups. Fullness in the epigastrium. Sweating with chills. Rebellious Qi and cough. Malaria with shivering cold. Abdominal distension with salivation. Dry lips with desire to drink but inability to swallow. Abdominal bloating. Hand spasms and finger pain. Chills with jaw clenching. Noises in the throat.
Acupuncture and Moxibustion: Prick with a three-edged needle to allow slight bleeding to drain heat from the Zang organs. Moxibustion is contraindicated.
Commentary: Shaoshang is the beginning of the Wood Jing-Well point of the Yin channel. The West corresponds to the color white and connects internally to the Lung. Its musical note is Shang (Metal). It is called "Shao" (Lesser) because the Five Zang are Yin, and Yin is often deficient.
2. Yuji (Ying-Spring Point)
Location: In the dispersed vessels on the radial side, proximal to the first metacarpophalangeal joint.
Indications and Treatments: Aversion to wind and cold with shivering. Deficiency heat. Yellow tongue coating. Fever, headache, cough, and anhidrosis. Bi syndrome wandering to the chest and back causing pain. Dyspnea. Vertigo and restlessness. Shortness of Qi. Abdominal pain and inability to eat. Elbow spasm with a sensation of fullness. Dry throat. Chills with jaw clenching. Cough radiating pain to the sacrum. Urinary incontinence. Hematemesis. Heart Bi. Sadness and fear.
Acupuncture and Moxibustion: Insert 0.2 cun, retain for three breaths.
Commentary: Yuji is the Fire Ying-Spring point of the Yin channel, located in the thenar eminence (fish belly) at the posterior aspect of the thumb. When the thumb is adducted toward the index finger, the thenar eminence is full; when abducted, the medial side proximal to the joint sinks slightly, resembling the junction in the center of a fish's belly, hence the name Yuji. As a Fire point and the Lung being a Metal organ, Fire overcomes Metal; therefore, this point is indicated for acupuncture only, not moxibustion.
3. Taiyuan (Shu-Stream Point / Yuan-Source Point)
Location: In the depression distal to the wrist crease.
Indications and Treatments: Chest Bi with rebellious Qi. Cold reversal with frequent hiccups and vomiting. Cough after drinking water. Restlessness and insomnia. Pulmonary distension and bloating. Pain along the medial aspect of the arm. Leucoma (white opacity) of the eye. Congested conjunctival vessels. Radiating pain in the supraclavicular fossa. Heat in the palm. Frequent yawning. Asthma and dyspnea. Belching with upward rebellion. Heart pain with hemoptysis. Chills. Dry throat. Delirium and facial paralysis (deviation of mouth and eye).
Acupuncture and Moxibustion: Insert 0.2 cun. Moxibustion of three moxa cones is permissible.
Commentary: Taiyuan is the convergence of the vessels. The *Ben Shu* chapter states: "One cun distal to Yuji in the depression." This is the Shu point. It is located one cun distal to the thenar eminence, which is the starting point of the Cun Kou pulse. It is the Shu point of the Five Zang organs and is also referred to as the Yuan-Source point. Because the essence of food and water from the Six Fu organs flows into the origin of the Five Zang meridians, it is named Yuan (Abyss).
4. Jingqu (Jing-River Point)
Location: In the depression at the Cun Kou pulse site.
Indications and Treatments: Alternating chills and fever in malaria. Stiffness and tension in the chest and back. Chest distension. Throat Bi. Heat in the palm. Cough with upward rushing Qi. Frequent yawning. Febrile disease with anhidrosis. Sudden Bi syndrome with asthma. Pain in the sole of the foot. Vomiting.
Acupuncture and Moxibustion: Insert 0.2 cun, retain for three breaths. Moxibustion is strictly prohibited, as it damages the Shen (Spirit).
Commentary: Jingqu is located within the Cun Kou, where the pulse moves without staying fixed, corresponding to the Guan position. The distance from Cun to Guan is 1.9 cun; below this is the Chi position. It is called Jingqu (River Channel) because it is a major thoroughfare. Taiyuan is at the beginning of Cun Kou, while Jingqu is in the middle of Cun Kou, not yet entering the Chi position.
5. Chize (He-Sea Point)
Location: In the artery at the midpoint of the cubital crease.
Indications and Treatments: Wind Bi with elbow spasm. Inability to raise the arm. Throat Bi with upward rushing Qi. Dry tongue. Cough with expectoration of turbid sputum. Sudden edema of the four limbs. Cold arms and shortness of Qi.
Acupuncture and Moxibustion: Insert 0.3 cun. Moxibustion of five moxa cones is permissible.
Commentary: Chize is the He-Sea point of the Lung meridian, suitable for both acupuncture and moxibustion. Since the He-Sea points of Yin channels belong to Water, and the Lung is a Metal organ, Water is generated by Metal (Metal generates Water). For excess pathogens, acupuncture is used to drain its "Son" (Water is the Son of Metal), thus draining the Son. The Lung stores Zang Qi, and mountains communicate with marshes. This point is precisely located at the Chi section of the Taiyin meridian, which is the knotting point of the pulse, hence named Chize. The meaning is profound.
