是主液所生病者 张云。小肠主泌别清浊。病则水谷不分。而流衍无制。是主液所生病也。志云。
小肠为受盛之官。化水谷之精微。故主液。
起于目内 上额交巅 滑氏云。目大角为内 。发际前为额。脑上为巅。巅、顶也。足太阳起目
内、睛明穴。上额循攒竹。过神庭。历曲差、五处、承光、通天。自通天斜行左右。相交于巅上之百会也。

内分作四行而下。此节言内两行者。夹脊两旁各相去一寸半。自大杼、行风门、及脏腑诸 。而抵腰中等穴
也。中行椎骨曰脊。臀骨上曰腰。
入循膂络肾属膀胱 张云。自腰中入膂络、肾前属膀胱。肾与膀胱为表里也。夹脊两旁之肉曰膂。
从腰中下挟脊贯臀入 中 甲乙。铜人挟脊。作会于后阴四字。发挥集书。无挟脊二字。马云。从

委阳穴也。从委阳下行 中。约纹动脉陷中。伏卧取之。即委中穴也。以上诸穴。皆属足太阳膀胱经。
胃口：张景岳注。胃的下口，位于下脘穴的部位，《难经》称之为幽门。
循腹里：张景岳注。经过足少阴肾经肓膜之外，这就是上文提到的分支脉，从胃下行，与直行脉在气街穴处汇合。
以下髀关（止）入中指内间：滑寿注。抵、至的意思。大腿外侧为髀，髀前膝上隆起的肌肉处为伏兔穴，伏兔后方的横纹处为髀关穴，挟持膝盖骨中间为膑骨，小腿骨为胫骨，跗指足背。既然在气冲穴相合，便向下经过髀关、抵达伏兔、经过阴市、梁丘，向下进入膝盖膑骨中，经过犊鼻，向下沿胫骨外侧的三里、巨虚上廉、条口、巨虚下廉、丰隆、解溪，下到足背的冲阳、陷谷，进入中指外侧的内庭穴，到达厉兑穴而结束。滑寿认为“马”注中的“内间”应作“外间”，这是错误的。
下廉三寸：廉，《甲乙经》和《铜人腧穴针灸图经》发挥篇作“膝”。滑寿注。这个分支从膝下三寸处，沿着三里穴的外侧，另行向下行走，进入中指外侧，与前文提到的内庭、厉兑汇合。马云注。从膝下三寸处，沿着三里穴的外侧别行向下，经过上廉、条口、下廉、丰隆、解溪、冲阳、陷谷，直到内庭、厉兑汇合。张景岳注。廉，指上廉。下廉三寸即丰隆穴，这是阳明经的别络，所以向下进入中指外侧。简案：马注将以上廉等六个穴位作为支脉所属，是错误的。
入大指间出其端：滑寿注。这个分支从足背上的冲阳穴别行，进入大脚趾之间，斜出足厥阴肝经行间穴的外侧，沿着大脚趾下方出于其末端，以交于足太阴脾经。汪机注。到达厉兑穴而终止，以交于足太阴经。按：凡是经脉交接传注，都属于支脉。《经别》篇又说：“上行通于心，沿咽喉退行过食管门，上达额部，回连目系。”
洒洒振寒：洒，《甲乙经》作“淅”，《铜人》作“洒”。《脉解》篇说：阳明经所说的洒洒然恶寒战栗，是因为阳明对应午时，是五月盛阳中的阴气。阳气极盛而阴气加之，所以洒洒然感到寒冷战栗。简案：马注引用《疟论》，说阳明虚则寒栗鼓颔，恐怕不对。
善呻善欠：《甲乙经》和《铜人》中，“伸”作“呷”。《铜人》注云：伸指伸展筋骨。张景岳注。这是胃气郁结所致。张志聪注。善于呻吟是因为阳气郁结想要伸出，频繁呵欠是因为阳气想要向上引动。
颜黑：《铜人》注云：颜指额头。张景岳注。黑是水色。土病则水无所畏惧，所以黑色反而见于颜面。
病至弃衣而走：《阳明脉解》篇说：阳明主肌肉，其脉血气旺盛，邪气客居则发热，热甚则厌恶火。又说：阳明经气逆乱则喘息且心中烦闷，烦闷则厌恶见人。又说：胃属土，所以听到木音就惊恐的，是因为土恶木。又说：四肢是诸阳之本，阳气盛则四肢充实，充实就能登高。又说：热盛于身，所以脱衣想跑。《脉解》篇说：所谓严重到厥逆，厌恶人和火，听到木音就惕然而惊的，是阳气与阴气相搏，水火相恶，所以惕然而惊。所谓想要独自关门闭窗居住的，是阴阳相搏。阳尽而阴盛，所以想要闭门居住。
贲响：张景岳注。肠胃雷鸣声。简案：《寿夭刚柔》篇中“怫忾贲响”，意义相同。
胫 厥：张景岳注。 ，指小腿肚。阳明经脉，从膝盖膑骨下沿胫骨外侧，所以称为胫 厥逆。 ，音干。
是主血所生病者：张景岳注。中焦受纳谷物，变化而赤成为血，所以阳明是多气多血的经脉，而主治血所生的疾病。张志聪注。本经说：谷入于胃，脉道通畅，血气乃行。《平脉篇》说：水入于经，而血乃成。胃为水谷之海，主要生成营血，所以说主治血所生的疾病。
狂疟温淫汗出：《甲乙经》中，“疟”作“瘧”。张景岳注。阳明热胜则发狂，风胜则患疟疾，温气淫溢则汗出。
唇胗：张志聪注。胗，同疹，指嘴唇生疮疡。简案：志注依据《说文解字》。《甲乙经》中，“胗”作“紧”。
身以前皆热：《铜人》注云：腹为阴，背为阳。足阳明行于身体前面（阴面），其气旺盛，所以身体前面都热。如果其气不足，所以身体前面都寒冷战栗。
消谷善饥：张志聪注。阳明之气盛于外，则身体前面都热；盛于内则胃有余，从而消化食物快且容易饥饿。溺色黄。
起于大趾之端：滑寿注。起于大脚趾端的隐白穴，接受足阳明的交会。
核骨：核，《发挥》作“ ”。滑寿注。俗称孤拐骨。楼氏注。核骨在大脚趾本节后约二寸处，内踝骨前约三寸，像枣核一样，横于足内侧赤白肉际处。窦大师将其指为孤拐骨是不对的。张景岳注。核骨即大脚趾本节后内侧的圆骨。滑寿说是孤拐骨，不对。因为孤拐即指踝骨，古有击踝的说法，即今北方人所谓的打孤拐。
上内踝前廉：滑寿注。经过核骨后，历太白、公孙、商丘，上至内踝前廉的三阴交穴。足跟后两旁隆起的骨头为踝骨。张景岳注。滑寿以足跟骨为踝，也不对。因为那叫跟踵，不是踝。
内：《铜人》注云。 ，指小腿肚。滑寿注。 ，腓肠肌。由三阴交上行至 内，沿 骨后的漏谷穴，上行二寸，交出足厥阴经之前，至地机、阴陵泉。张景岳注。 ，足肚，也叫腓肠。本经中与 通用，音篆。盖 、本音 。《玉篇》以足跟为 。简案： 、《说文解字》指腓肠肌。
上膝股内前廉入腹属脾：滑寿注。大腿内侧为股，脐上下为腹。自阴陵泉上行，沿膝股内前廉的血海、箕门，蜿蜒入腹，经过冲门、府舍，会于中极、关元，再循腹结、大横，会于下脘，历腹哀，过日月、期门之分，循本经之里，下至中脘、下脘之际，以属脾络胃。
上膈（止）散舌下：滑寿注。咽是吞咽食物的部位，位于喉前，舌本即舌根。由腹哀上行过膈，循食窦、天溪、胸乡、周荣，由周荣外曲折向下，至大包上行，行人迎之里，挟咽连舌本，散于舌下。
其支者（止）注心下：张景岳注。足太阴经外行的部分，由腹部四行上行至府舍、腹结等穴，散于胸中，止于大包。其内行而分支的部分，自胃脘别出上行过膈，注入心中，而接手少阴心经。
食则呕（止）快然如衰：《脉解》篇说：太阴经所说的进食则呕吐，是因为食物满盛而上溢，所以呕吐。所谓病胀，是因为太阴对应子月（十一月），万物之气都藏于中，所以叫病胀。所谓气上走心为噫，是因为阴盛而上走于阳明，阳明络属于心，所以叫上走心为噫。所谓得大小便及矢气则舒服减轻，是因为十一月阴气下衰，而阳气将出，所以叫得后与气则快然如衰。如衰，《甲乙经》作而衰。简案：而、如古字相通。李云：后指大便，气指转矢气。
烦心心下急痛：《甲乙经》中，“痛”作“寒疟”二字。马云注：脉注心中。
溏瘕泄水闭黄胆：马云注。溏，脾气不实。瘕泄，《难经·五十七难》有大瘕泄。水闭，《六元正纪大论》有甚则水闭跗肿，指水蓄于内，而大小便皆闭。黄胆，《素问·平人气象论》、《本经论疾诊尺篇》皆有黄胆。张景岳注。脾寒则为溏泻，脾滞则为症瘕，脾病不能制水，则为泄、为水闭、黄胆，不能卧。李云：溏是水泄，瘕是痢疾，水闭是上病不能治水，水闭则湿热壅而为疸，为不卧。
不能卧：《甲乙经》中，“卧”作“食”，下有“食下有唇青”二字。《铜人》注云：《甲乙经》作“好卧不能食肉，唇青强立”，与今本不同。
强立：各家不解释。简案：大概指勉强而起立，则股膝内侧肿胀。《甲乙经》肿下有“痛”字。
足大趾不用：张景岳注。脾脉起于足拇趾以上，沿膝股内廉，所以出现肿、厥、大趾不能用等病。
起于心中：杨上善注。经说：心在肺下。又说心状如未开的莲花，在膈上附第五椎。简案：据杨注，心中直指心脏而言。
心系：道藏本脱去“系”字。滑寿注。心系有两个，一个向上与肺相通，进入肺两大叶之间；一个由肺叶向下，曲折向后，并脊膂细络相连，贯脊髓与肾相通，正当七节之间。盖五脏系皆通于心，而心通五脏系。手少阴经起于心，循任脉之外属心系，下膈，当脐上二寸之分，络小肠。张景岳注。其系有五个，上系连肺，肺下系心，心下三系连脾、肝、肾，所以心通五脏之气而为之主。
目系：杨上善注。《要旨论》说：目内连深处为目系。此经已络小肠，从心系分支横出，循任脉之外，上挟咽系，而行至于目系。
其直者（止）出腋下：滑寿注。直行者复从心系直上至肺脏之分，出循腋下抵极泉穴。穴在臂内、腋下、筋间、动脉处。张景岳注。手少阴经，行于外的部分始于此。
下循 内后廉（止）下肘内：《甲乙经》作肘中内廉。滑寿注。自极泉下行，沿 内后廉，行于太阴、心主两经之后，历青灵穴，下至肘内廉，抵少海。
循臂内（止）出其端：滑寿注。腕下踝为兑骨，自少海而下循臂内后廉，历灵道、通里，至掌后锐骨之端，经阴 、神门，入掌内廉，至少府，循小指端之少冲，而终以交于手太阳经。心为君主之官，示尊于它脏，所以其交经授受，不假于支别。
嗌干（止）臂厥：张景岳注。本经支者从心系上挟咽，所以为嗌干心痛。心火炎则心液耗，所以渴而欲饮。手少阴循臂内后廉，出小指之端，所以为臂厥。
目黄胁痛（止）掌中热痛：张景岳注。少阴之脉，系目系，所以目黄。出腋下，所以胁痛。循 臂内入掌内后廉，所以为热痛诸病。《甲乙经》中，胁下有“满”字。

颔肿：《铜人》注云：颔，谓颊下也。张景岳注。本经之脉，循咽下膈，其支者循颈上颊，故为此病。
是主液所生病者：张景岳注。小肠主泌别清浊，病则水谷不分，而流衍无制，是主液所生病。张志聪注。小肠为受盛之官，化水谷之精微，故主液。
起于目内 （止）上额交巅：滑寿注。目大角为内眦，发际前为额，脑上为巅，巅即顶。足太阳起目内眦睛明穴，上额循攒竹，过神庭，历曲差、五处、承光、通天，自通天斜行左右，相交于巅上之百会。《铜人》注云：内眦，谓目之大眦也。
介按：目内眦外一分宛宛中，是睛明穴。上行眉，眉头陷中，即攒竹穴。再上行发际间，侠督脉之神庭穴，旁开一寸五分，正头取之，是曲差穴。后行五分，旁开一寸五分，五处穴。从此后行一寸五分，承光穴。由承光后行一寸五分，侠督脉之百会穴，旁开一寸五分，即通天穴。
其支者从巅至耳上角：滑寿注。抵耳上角，过率谷、浮白、窍阴穴，所以散养于经脉。张景岳注。由百会旁行至耳上角，过足少阳之曲鬓、率谷、天冲、浮白、窍阴、完骨，故此六穴者，皆为足太阳少阳之会。
介按：从悬厘后行耳前，入发际曲隅陷中鼓颔有空，即曲鬓穴。后行耳上，入发际寸半陷者宛宛中，嚼牙取之，即率谷穴。从此后行耳后三分许，入发际二寸，天冲穴。下行耳后，入发际一寸，浮白穴。由此下行耳后，高上枕骨下摇动有穴，窍阴穴。从窍阴行耳后，入发际四分，即完骨穴。

Stomach opening: Zhang Jingyue's annotation. The lower opening of the stomach, located at the level of the Xiawan (Lower Confluence) acupoint; this is what the *Nan Jing* (Classic of Difficult Issues) refers to as the Youmen (Gate of the Stomach).
Following inside the abdomen: Zhang Jingyue's annotation. Passing outside the *huang* membrane (a term referring to the deep fascia or cavity between the heart and diaphragm) of the Foot-Shaoyin Kidney Meridian. This is the branch mentioned earlier, descending from the stomach and merging with the main trunk in the Qi Street (Qichong region).
Descending below Bituan (ST31), entering between the inner aspect of the middle toe: Hua Shou's annotation. "Di" and "Zhi" mean to reach. The lateral thigh is called "Bi". The fleshy prominence anterior to the knee is the Futu (ST32) area. The transverse crease posterior to Futu is Bituan (ST31). The space flanking the patella is the Bin bone. The tibia is the "Jing" bone. "Fu" refers to the dorsum of the foot. After merging at Qichong (ST30), it descends below Bituan (ST31), reaches Futu (ST32), passes Yinshi (ST33), Liangqiu (ST34), enters the patellar region, passes Dubi (ST35), and follows the lateral border of the tibia through Zusanli (ST36), Shangjuxu (ST37), Tiaokou (ST38), Xiaguxu (ST39), Fenglong (ST40), and Jiexi (ST41). It then descends to the dorsum of the foot, reaching Chongyang (ST42) and Xangu (ST43), enters between the outer aspect of the middle toe at Neiting (ST44), and terminates at Lidui (ST45). Hua Shou states that Ma's note reading "inner aspect" should be "outer aspect"; this is incorrect.
Three cun below Lian: In *Jia Yi Jing* and the *Tong Ren* commentary, "Lian" is written as "Xi". Hua Shou's annotation. This branch originates three cun below the knee, running laterally to the Zusanli (ST36) acupoint, diverging downward, entering the outer aspect of the middle toe, and merging with the previously mentioned Neiting (ST44) and Lidui (ST45). Ma Yu's annotation. From three cun below the knee, it runs laterally to Zusanli (ST36), diverging downward through Shangjuxu (ST37), Tiaokou (ST38), Xiaguxu (ST39), Fenglong (ST40), Jiexi (ST41), Chongyang (ST42), and Xangu (ST43), until merging at Neiting (ST44) and Lidui (ST45). Zhang Jingyue's annotation. "Lian" refers to Shangjuxu (ST37). Three cun below Xiaguxu (ST39) is the Fenglong (ST40) acupoint, which is the Luo-connecting vessel of the Yangming Meridian; thus, it descends into the outer aspect of the middle toe. Brief analysis: Ma's classification of the six acupoints above as belonging to the branch is erroneous.
Entering between the big toe and emerging at its tip: Hua Shou's annotation. This branch diverges from the Chongyang (ST42) acupoint on the dorsum of the foot, enters between the big toe, exits obliquely lateral to the Xingjian (LR2) acupoint of the Foot-Jueyin Liver Meridian, follows the big toe downward to emerge at its tip, and connects with the Foot-Taiyin Spleen Meridian. Wang Ji's annotation. It terminates at Lidui (ST45) to connect with the Foot-Taiyin Spleen Meridian. Commentary: All meridian intersections and transmissions belong to branch vessels. The *Jing Bie* chapter also states: "Ascends to connect with the Heart, follows the pharynx, passes the esophagus, reaches the forehead, and returns to connect with the Eye System."
Chilly shivering: In *Jia Yi Jing*, "Sa" is written as "Xi"; in *Tong Ren*, it is "Sa". The *Mai Jie* chapter states: Regarding Yangming's "chilly shivering," Yangming corresponds to Wu (noon), representing the yin within the peak yang of the fifth month. When yang is excessive and yin qi adds to it, one feels chilly and shivers. Brief analysis: Ma cites the *Nu Lun* (Treatise on Malaria), stating that deficiency of Yangming causes cold chills with jaw trembling; this is likely incorrect.
Frequent groaning and yawning: In *Jia Yi Jing* and *Tong Ren*, "Shen" (stretch) is written as "Xia". *Tong Ren* annotation: Shen refers to stretching the sinews and bones. Zhang Jingyue's annotation: This indicates stagnation of Stomach qi. Zhang Zhicong's annotation: Frequent groaning occurs when yang qi is stagnant and desires to extend; frequent yawning occurs when yang qi desires to rise.
Darkening of the face: *Tong Ren* annotation: Yan refers to the forehead. Zhang Jingyue's annotation: Black is the color of Water. When Earth (Spleen/Stomach) is diseased, it cannot control Water, so the black color appears on the face.
Disease onset: discarding clothes and running: The *Yangming Mai Jie* chapter states: Yangming governs the flesh; its vessels are abundant in blood and qi. When pathogenic factors invade, heat arises; extreme heat leads to aversion to fire. It also states: Yangming reversal causes panting and distress; distress leads to aversion to people. It also states: The Stomach belongs to Earth, so hearing Wood sounds causes alarm because Earth fears Wood. It also states: The four limbs are the root of all yang; when yang is excessive, the limbs become solid and strong, enabling climbing high. It also states: Extreme heat in the body causes one to discard clothes and run. The *Mai Jie* chapter states: Severe cases involve reversal, aversion to people and fire, and alarm upon hearing Wood sounds due to the struggle between yang and yin qi, and the conflict between water and fire. Cases where patients desire to close doors and windows alone occur because yin becomes excessive after yang is exhausted.
Borborygmus: Zhang Jingyue's annotation: Rumbling noises in the intestines and stomach. Brief analysis: The *Shou Yao Gang Rou* chapter mentions "fukai benxiang," which has the same meaning.
Jing Ju (Calf Reversal): Zhang Jingyue's annotation: "Jing" refers to the calf muscle. The Yangming meridian descends from the knee patella along the lateral border of the tibia; thus, it is called Jing Ju Ju Ni (Reversal in the Calf). "Ju" is pronounced "gan."
Governs diseases generated by Blood: Zhang Jingyue's annotation: The Middle Jiao receives grain, transforms it, and changes it into red blood; therefore, Yangming is a meridian abundant in both qi and blood, governing diseases generated by blood. Zhang Zhicong's annotation: The Classic states: Grain enters the stomach, meridians become unobstructed, and blood and qi flow. The *Ping Mai* chapter states: Water enters the meridians, and blood is formed. The Stomach is the Sea of Water and Grain, primarily generating Ying (Nutritive) Blood; hence, it governs diseases generated by blood.
Mania, malaria, warm pathogens causing sweating: In *Jia Yi Jing*, "Nue" is written as "Mang". Zhang Jingyue's annotation: Excessive heat in Yangming causes mania; wind excess causes malaria; exuberant warm qi causes sweating.
Cheilosis (Ulcers on lips): Zhang Zhicong's annotation: "Zhen" is synonymous with "Zhen" (rash); it refers to ulcers on the lips. Brief analysis: Zhicong's note is based on the *Shuo Wen Jie Zi*. In *Jia Yi Jing*, "Zhen" is written as "Jin".
Edema of the great abdomen: Zhang Jingyue's annotation: The Stomach is in the Middle Jiao; when Earth is diseased, it cannot control water.
Heat throughout the anterior body: *Tong Ren* annotation: The abdomen is yin, the back is yang. The Foot-Yangming travels along the anterior (yin) aspect of the body; its qi is vigorous, so the anterior body feels hot. If its qi is deficient, the anterior body feels cold and shivery.
Rapid digestion and easy hunger: Zhang Zhicong's annotation: Yangming qi is excessive externally, causing heat in the anterior body; excessively internally, it results in surplus in the Stomach, leading to rapid digestion and easy hunger. Urine is yellow.
Originating at the tip of the big toe: Hua Shou's annotation: Originates at the tip of the big toe, the Yinbai (SP1) acupoint, receiving the intersection of the Foot-Yangming.
Following the medial white flesh margin of the toe: Zhang Jingyue's annotation: Passes through the Dabu (SP2) and Taibai (SP3) acupoints.
Hegu Bone: "He" is written as " " in *Fa Hui*. Hua Shou's annotation: Commonly known as the "Gu Gua Gu" (isolated turn bone). Lou's annotation: The Hegu bone is approximately two cun posterior to the metatarsophalangeal joint of the big toe, about three cun anterior to the medial malleolus, resembling a jujube pit, lying transversely on the medial side of the foot at the junction of red and white flesh. Dou Dashier's identification of it as the Gu Gua Gu is incorrect. Zhang Jingyue's annotation: The Hegu bone is the round bone on the medial side posterior to the big toe's metatarsophalangeal joint. Hua Shou's claim that it is the Gu Gua Gu is incorrect because Gu Gua refers to the malleolus; ancient texts mention striking the malleolus, which northerners today call hitting the "Gu Gua."
Ascending to the anterior edge of the medial malleolus: Hua Shou's annotation: Passing posterior to the Hegu bone, through Taibai (SP3), Gongsun (SP4), and Shangqiu (SP6), ascending to the anterior edge of the medial malleolus at Sanyinjiao (SP6). The bones rising on both sides posterior to the heel are the malleoli. Zhang Jingyue's annotation: Hua Shou identifying the calcaneus as the malleolus is also incorrect; that is called the Gen Zhong (heel), not the malleolus.
Inside the Jing (Calf): *Tong Ren* annotation: "Jing" refers to the fish-belly shape of the tibia. Hua Shou's annotation: "Jing" is the gastrocnemius. From Sanyinjiao (SP6), it ascends into the Jing (calf), follows the Leigu (SP9) acupoint posterior to the Jing bone, ascends two cun, crosses anterior to the Foot-Jueyin Liver Meridian, reaching Diji (SP8) and Yinlingquan (SP9). Zhang Jingyue's annotation: "Jing" is the calf belly, also named Gastrocnemius. In this Classic, "Jing" and " " are used interchangeably, pronounced "Zhuan." The *Yu Pian* defines the heel as " ". Brief analysis: "Jing" and *Shuo Wen* refer to the gastrocnemius.
Ascending past the knee, medial anterior thigh edge, entering the abdomen, connecting to the Spleen: Hua Shou's annotation: The medial thigh is the "Gu." The area above and below the navel is the "Abdomen." Ascending from Yinlingquan (SP9), following the medial anterior edge of the knee and thigh through Xuehai (SP10) and Jimen (SP11), it winds into the abdomen, passing Chongmen (SP12), Fushhe (SP13), meeting Zhongji (CV3) and Guanyuan (CV4), then following Fujie (SP14) and Daheng (SP15), meeting Xiawan (CV10), passing Fu'ai (SP16), over Riyue (GB24) and Qimen (LR14), following the interior of this meridian, descending to the junction of Zhongwan (CV12) and Xiawan (CV10), connecting to the Spleen and linking to the Stomach.
Ascending through the Diaphragm (terminating) and dispersing under the tongue: Hua Shou's annotation: The pharynx is for swallowing food, located anterior to the larynx. The "She Ben" is the root of the tongue. From Fu'ai (SP16), it ascends through the diaphragm, following Shidou (ST17), Tianxi (ST21), Xiongxiang (ST22), and Zhourong (ST23). From Zhourong, it curves outward and downward to Dabao (SP21), ascends, enters the interior of Renying (ST9), flanks the pharynx, connects to the root of the tongue, and disperses under the tongue.
Its branch (terminating) injecting into the lower Heart: Zhang Jingyue's annotation: The external pathway of the Foot-Taiyin Meridian ascends from the abdomen through four rows to Fushhe (SP13), Fujie (SP14), etc., dispersing in the chest and terminating at Dabao (SP21). Its internal branch diverges from the stomach cavity, ascends through the diaphragm, injects into the Heart, and connects with the Hand-Shaoyin Heart Meridian.
Vomiting after eating (terminating) feeling relieved as if subsiding: The *Mai Jie* chapter states: Regarding Taiyin's "vomiting after eating," it is because food is full and overflows upward, causing vomiting. Regarding "distension disease," Taiyin corresponds to the Zi month (November); when the qi of all things hides within, it is called distension disease. Regarding "qi moving up to the Heart causing belching," it is because yin excess moves up to Yangming, and Yangming links to the Heart, hence "moving up to the Heart causes belching." Regarding "relief after defecation and passage of gas," it is because in November, yin qi declines downward while yang qi begins to exit; thus, "obtaining stool and gas brings relief." "Ru Shuai" (as if subsiding) is written as "Er Shuai" in *Jia Yi Jing*. Brief analysis: "Er" and "Ru" were interchangeable in ancient times. Li Yun states: "Hou" refers to feces; "Qi" refers to flatus.
Heavy sensation throughout the body: *Tong Ren* annotation: Since the Spleen governs the muscles, distension disease causes heaviness in the body.
Pain at the root of the tongue: Ma Yu's annotation: The previous section mentioned stiffness at the root of the tongue; here, pain is more severe.
Inability to move or shake the body: Ma Yu's annotation: This refers to the severity of the heaviness mentioned above.
Restlessness, urgency, and pain in the Heart region: In *Jia Yi Jing*, "Tong" (pain) is written as "Han Nue" (cold malaria). Ma Yu's annotation: The pulse injects into the Heart.
Loose stools, mass diarrhea, water retention, anuria, jaundice: Ma Yu's annotation: Loose stools indicate spleen qi insecurity. Mass diarrhea is described in the *Nan Jing* (Chapter 57) as "Da Xia Xie." Water retention/anuria is mentioned in the *Liu Yuan Zheng Ji Da Lun* as "severe water retention causing edema," indicating water accumulation internally with blockage of both urination and defecation. Jaundice is discussed in the *Su Wen Ping Ren Qi Xiang Lun* and *Ben Jing Lun Ji Chi Pian*. Zhang Jingyue's annotation: Spleen cold causes loose diarrhea; spleen stagnation causes masses; spleen disease failing to control water causes diarrhea, water retention, and jaundice, preventing sleep. Li Yun states: Loose stools are watery diarrhea; Xia is dysentery; water retention is the upper body's inability to manage water; water retention leads to damp-heat congestion causing jaundice and insomnia.
Inability to lie down: In *Jia Yi Jing*, "Wo" (lie down) is written as "Shi" (eat), with the addition of "after eating, lips turn blue." *Tong Ren* annotation: *Jia Yi Jing* reads "prefers lying down, unable to eat meat, lips blue, forced standing," which differs from the current text.
Forced standing: Unexplained by various commentators. Brief analysis: It likely means forcing oneself to stand up, causing swelling in the thighs and knees. *Jia Yi Jing* adds the character "Tong" (pain) after "Zhong" (swelling).
Inability to use the big toe: Zhang Jingyue's annotation: The Spleen meridian originates above the big toe and follows the medial knee and thigh; thus, it causes diseases such as swelling, reversal, and inability to use the big toe.
Originating in the Heart: Yang Shangshan's annotation: The Classic states: The Heart is below the lungs. It also states: The Heart resembles an unopened lotus flower, located above the diaphragm attached to the fifth thoracic vertebra. Brief analysis: According to Yang's note, "Heart center" refers directly to the cardiac organ.
Heart connections: The Daozang edition omits the character "Xi" (connection). Hua Shou's annotation: There are two heart connections: one connects upward to the lungs, entering between the two large lobes of the lungs; the other descends from the lung lobes, curves backward, connects via fine networks along the spine and marrow, penetrates the spinal cord to communicate with the kidneys, situated exactly at the seventh vertebral segment. Generally, the connections of the five zang organs all communicate with the Heart, and the Heart communicates with the connections of the five zang organs. The Hand-Shaoyin Heart Meridian originates in the Heart, follows the exterior of the Ren Mai, connects to the heart connections, descends through the diaphragm, reaches two cun above the navel, and links to the Small Intestine. Zhang Jingyue's annotation: There are five connections: the upper connection links to the lungs, the lung's lower connection links to the Heart, and the Heart's lower three connections link to the Spleen, Liver, and Kidneys. Thus, the Heart communicates with the qi of the five zang organs and serves as their master.
Eye connections: Yang Shangshan's annotation: The *Yao Zhi Lun* states: The deep interior connection of the eye is the Eye Connection. This meridian has already linked to the Small Intestine; from the heart connections, a branch emerges horizontally, follows the exterior of the Ren Mai, ascends flanking the pharynx, and reaches the Eye Connections.
Its main trunk (terminating) exiting the axilla: Hua Shou's annotation: The main trunk ascends straight from the heart connections to the lung region, exits, follows the axilla to reach Jiquan (HT1). The acupoint is located in the arm, axilla, between tendons, and over an artery. Zhang Jingyue's annotation: This marks the beginning of the external pathway of the Hand-Shaoyin Pericardium/Meridian.
Descending along the posterior medial border of the arm (terminating) below the elbow: *Jia Yi Jing* reads "medial edge of the elbow." Hua Shou's annotation: Descending from Jiquan (HT1) along the posterior medial border of the arm, running posterior to the Taiyin and Pericardium meridians, passing Qingling (HT8), descending to the medial edge of the elbow, reaching Shaohai (HT3).
Following the inner arm (terminating) emerging at its tip: Hua Shou's annotation: The ankle below the wrist is the Duigǔ. Descending from Shaohai (HT3) along the posterior medial border of the arm, passing Lingdao (HT4) and Tongli (HT5), reaching the end of the sharp bone posterior to the palm, passing Yinxi (HT2) and Shenmen (HT7), entering the medial palm, reaching Shaofu (HT8), following the tip of the little finger to Shaochong (HT9), and terminating to connect with the Hand-Taiyang Bladder Meridian. The Heart is the Sovereign Official, showing respect above other zang organs; thus, its meridian transmission does not rely on branch vessels.
Dry throat (terminating) Arm Reversal: Zhang Jingyue's annotation: The branch of this meridian ascends from the heart connections flanking the pharynx, causing dry throat and heart pain. When heart fire blazes, heart fluids are consumed, causing thirst and desire to drink. The Hand-Shaoyin follows the posterior medial border of the arm, emerging at the tip of the little finger, causing Arm Reversal.
Yellow eyes, hypochondriac pain (terminating) Heat and pain in the palm: Zhang Jingyue's annotation: The Shaoyin meridian connects to the Eye Connections, causing yellow eyes. It exits the axilla, causing hypochondriac pain. It follows the arm inner side into the posterior medial palm, causing heat and pain. *Jia Yi Jing* adds the character "Man" (fullness) after "Xie" (hypochondrium).
Originating at the tip of the little finger (terminating) exiting the ankle: Hua Shou's annotation: The end of the arm bone is the wrist; the Duigǔ below the wrist is the ankle. This meridian originates at the tip of the little finger, the Shaoze (SI1) acupoint. From there, it follows the anterior aspect of the lateral hand through Qian Gu (SI05), Hou Xi (SI3), ascends the wrist, exits the ankle, passing Wan Gu (SI4), Yang Gu (SI03), and Yang Lao (SI06).
Straight up following the lower border of the arm bone (terminating) crossing onto the shoulder: Hua Shou's annotation: The areas on both sides of the spine are Lü. The two angles above the Lü are Jianjie (shoulder resolution). The flat bone below Jianjie is the scapula (also called Bo). From Yang Lao (SI06), it goes straight up following the arm bone, passing the lower border branches Zheng and Zhi, exiting between the two bones on the medial side of the elbow, passing Xiaohai (SI08), ascending along the posterior lateral border of the arm, running external to the Hand-Yangming and Shaoyang meridians, ascending the shoulder through Jianzhen (SI09), Jianyu (LI15 - *Note: Text says ' ', likely Jianyu or similar*), Tianzong (SI11), Chengfeng (SI12), Quyuan (SI13), Jianwaishu (SI14), and Jianzhongshu (SI15), finally meeting Dazhui (GV14). Because they cross left and right above the shoulders. Zhang Jingyue's annotation: Following the lower border of the arm bone and Yanggu (SI03), exiting at Xiaohai (SI08) in the depression between the two bones of the elbow. Pressing here elicits sensation in the little finger. Brief analysis: *Jia Yi*, *Qian Jin*, and *Tong Ren* write "two bones"; Hua Shou follows this. However, pressing now causes numbness corresponding to the little finger, which is touching the tendon. The acupoint lies between the elbow bone and arm bone; thus, writing "bone" is correct.
Entering the Clavicular fossa (terminating) connecting to the Small Intestine: *Jia Yi Jing* adds "towards the axilla" after "Quepen." *Tong Ren* agrees. Zhang Jingyue's annotation: From Quepen (LI12), it descends through the chest, enters Danzhong (CV17), links to the Heart; the Heart and Small Intestine are exterior-interior partners. Below Quepen, it follows the pharynx, descends through the diaphragm to the Stomach, descends, reaching two cun above the navel, connecting to the Small Intestine. This is the internal pathway of this meridian.
Its branch (terminating) entering the ear: Hua Shou's annotation: The outer corner of the eye is Ruizi. The branch diverges from Quepen (LI12), follows Tianchuang (SI16) and Tianrong (SI17) in the neck, ascends to the cheek, reaches the zygoma, ascends to the outer canthus (Ruizi), passes Tongziliao (GB1), enters the ear, follows Tinggong (SI19), and terminates.
Its branch (terminating) obliquely linking to the zygoma: *Fa Hui* lacks the four characters "obliquely linking to the zygoma." This aligns with *Jin Lan Xun Jing*. Zhang Jingyue's annotation: Below the eye is , the inner corner of the eye is Neizi. The zygoma is the cheekbone. The Xiagu acupoint. The Hand-Taiyang intersects at the inner canthus here, connecting to the Foot-Taiyang Bladder Meridian. Brief analysis: Wang's annotation in the *Ci Jin Lun* states the Hand-Taiyang meridian travels obliquely from the zygoma to the inner canthus. The omission in *Fa Hui* is likely due to a textual loss.
Swelling of the jaw: *Tong Ren* annotation: Han refers to the area below the cheek. Zhang Jingyue's annotation: The meridian of this channel follows the pharynx down through the diaphragm; its branch follows the neck up to the cheek; thus, it causes this disease.
Governs diseases generated by Fluids: Zhang Jingyue's annotation: The Small Intestine separates the clear from the turbid. Disease causes failure to distinguish water and grain, leading to uncontrolled overflow; thus, it governs diseases generated by fluids. Zhang Zhicong's annotation: The Small Intestine is the Official of Reception and Transformation, transforming the essence of water and grain; thus, it governs fluids.
Originating at the inner canthus (terminating) ascending the forehead to cross the vertex: Hua Shou's annotation: The large angle of the eye is the inner canthus. The area anterior to the hairline is the forehead. The top of the head is the Dian (vertex). The Foot-Taiyang originates at the inner canthus, Jingming (BL1), ascends the forehead following Cuanzhu (BL2), passes Shenting (GV24), through Qucha (BL07), Wuchu (BL08), Chengguang (BL09), and Tongtian (BL10). From Tongtian, it diagonally crosses left and right, intersecting at Baihui (GV20) on the vertex. *Tong Ren* annotation: Inner canthus refers to the large angle of the eye.
Commentary by Jie: One fen lateral to the inner canthus in the depression is Jingming (BL1). Ascending to the eyebrow, in the depression at the head of the brow is Cuanzhu (BL2). Ascending further into the hairline, adjacent to the Du Meridian at Shenting (GV24), one cun five fen lateral, taken facing forward, is Qucha (BL07). Moving back five fen, one cun five fen lateral, is Wuchu (BL08). Moving back one cun five fen from here is Chengguang (BL09). Moving back one cun five fen from Chengguang, adjacent to the Du Meridian at Baihui (GV20), one cun five fen lateral, is Tongtian (BL10).
Its branch from the vertex to the upper angle of the ear: Hua Shou's annotation: Reaching the upper angle of the ear, passing Lvgu (GB08), Fubai (GB12), and Qiaoyin (GB11), to nourish the meridians. Zhang Jingyue's annotation: From Baihui (GV20), it moves laterally to the upper angle of the ear, passing the Foot-Shaoyang acupoints Qubin (GB07), Lvgu (GB08), Tianchong (GB15), Fubai (GB12), Qiaoyin (GB11), and Wangu (GB12). Thus, these six acupoints are intersections of the Foot-Taiyang and Foot-Shaoyang.
Commentary by Jie: Moving back from Xuanli (GB06) anterior to the ear, entering the hairline corner in the depression where the jaw moves, is Qubin (GB07). Moving up the ear, entering the hairline one cun half in the depression, taken while chewing, is Lvgu (GB08). Moving back three fen posterior to the ear from here, entering the hairline two cun, is Tianchong (GB15). Descending posterior to the ear, entering the hairline one cun, is Fubai (GB12). Descending posterior to the ear from here, the movable acupoint below the occipital bone is Qiaoyin (GB11). Moving posterior to the ear from Qiaoyin, entering the hairline four fen, is Wangu (GB12).
Its main trunk from the vertex enters and links to the brain: *Tong Ren* annotation: The top is the central top; anterior is the fontanelle top; posterior is the brain top; left and right are the angles. Hua Shou's annotation: The brain is head marrow. Above the neck is the brain; posterior to the neck is the nape. This straight path, from behind Tongtian (BL10), follows Luoque (BL06) and Yuzhen (GB09), entering and linking to the brain.
Returning out, diverging down the nape (terminating) reaching the waist: Zhang Jingyue's annotation: Emerging from the brain, it diverges down the nape, through Tianzhu (BL10), meeting Dazhui (GV14) and Daodao (GV13) of the Du Meridian. It then divides into four rows descending along the shoulder. This section discusses the two inner rows, located one cun half lateral to both sides of the spine, from Dazhu (BL11), Fengmen (BL12), and the various acupoints of the zang and fu organs, reaching the waist and other acupoints. The central column of vertebrae is called the spine; the bone above the buttocks is called the waist.
Entering, following the Lumbar muscles, linking to the Kidneys, connecting to the Bladder: Zhang Jingyue's annotation: Entering from the waist into the Lumbar muscles, linking to the Kidneys, anteriorly connecting to the Bladder; the Kidneys and Bladder are exterior-interior partners. The flesh on both sides of the spine is called Lü.
Descending from the waist, flanking the spine, penetrating the buttocks, entering the Popliteal fossa: *Jia Yi* and *Tong Ren* read "flanking the spine" as "meeting at the posterior orifice." *Fa Hui* collection lacks "flanking the spine." Ma Yu's annotation: Descending from the waist along the hip, flanking the spine, passing Shangliao (BL31), Ciliao (BL32), Zhongliao (BL33), Xialiao (BL34), and Huiyang (BL35), penetrating the buttocks, reaching Chengfu (BL36), Yinmen (BL37), Fubian (BL38), Weiyang (BL39), entering the Weizhong (BL40) acupoint in the Popliteal fossa. Hua Shou's annotation: The buttock is the Kao. The mechanism flanking the hip bone is Ji; posterior to Ji is the buttock. The bend posterior to the knee above the gastrocnemius is .
Commentary by Jie: One cun below the ankle bone, in the first depression flanking the spine, is Shangliao (BL31). In the second depression is Ciliao (BL32). In the third is Zhongliao (BL33). In the fourth is Xialiao (BL34). From Xialiao, moving five fen lateral to the coccyx and tailbone is Huiyang (BL35). From the lower buttock, in the crease of the upper thigh, is Chengfu (BL36). From Yinmen, moving diagonally up one cun, bending the knee to locate, is Fubian (BL38). Descending from Fubian, still six cun below Chengfu, taking it while extending and flexing, is Weiyang (BL39). Descending from Weiyang into the Popliteal fossa, in the depression of the arterial pulse at the crease, taken prone, is Weizhong (BL40). All the above acupoints belong to the Foot-Taiyang Bladder Meridian.
