足少阳胆经的经脉，起始于目外眦（锐眦），向上到达头角部，再向下经过耳后，沿着颈部行走，位于手少阳三焦经经脉的前方，至肩部时，转而交出于手少阳三焦经的后方（注：此处原文括号内解释为足少阳沿颈部行于手少阳之前，至肩部时，手少阳在其后，即足少阳在前）。进入缺盆（锁骨上窝）。其分支从耳后进入耳中，出走耳前，到达目外眦后方，下行至大迎穴处，与手少阳三焦经会合，上行至目眶下，下行加于颊车穴，再下行颈部，与缺盆处的经脉汇合，由此向下进入胸中，贯穿膈肌，联络肝脏（肝为胆之维系，故胆经脉络联系于肝），属于胆腑（足少阳胆经为胆之经脉，故其脉归属于胆）。沿胁肋内部走行，出于气冲穴（气冲穴位于腹脐下横骨两端鼠鼷上方，同身寸一寸处的动脉搏动中），环绕阴毛边缘，横向进入髀厌中（即环跳穴所在部位）。其直行者，从缺盆下行腋下，沿胸部经过季胁（肋骨称为肋，肋尽头处称为季胁），向下汇合于髀厌中，再向下沿大腿外侧（髀阳，即大腿外侧）行走，出于膝部外侧（阳陵泉穴所在部位），下行于腓骨前缘（辅骨，指辅助胫骨的腓骨，在胫骨之外），直下抵达绝骨末端（阳辅穴位于此绝骨之端），下行出于外踝前方（丘墟穴所在部位），沿足背行走，出于第四趾末端（第四趾末端为窍阴穴所居，《素问》云：少阳经气始于窍阴）。其分支，从足背分出，进入大脚趾之间，沿大脚趾歧骨内侧，出于其端，回绕穿过爪甲，出于丛毛处（足少阳胆经至此交接入足厥阴肝经）。
凡是经脉变动异常所致的病症（足少阳胆经通常血少气多，若气先发病，称为“是动病”），会出现口苦（《素问》云：口苦者，病名为胆瘅。此人平素谋虑不决，导致胆虚，气机上溢，因而口苦。治疗应取胆的募穴和俞穴）。喜欢长叹气（《灵枢经》说：人忧思则心脉拘急，心脉拘急则气道约束，约束则不通利，故通过长叹来舒展气机）。心胁部疼痛（《素问》所说的心胁痛，是指少阳经气盛。盛，是心的表证。九月阳气盛而阴气衰，所以说心胁痛）。身体不能转侧（《素问》所谓不可反侧，是因为九月阴气收藏，万物静止不动，所以身体不可反侧）。严重时面色如蒙尘垢（面微尘，谓面部像有微尘，呈现如尘土般的色泽），身体失去光泽润泽，足外侧发热，这称为阳厥。
本经主司骨骼，其所生的疾病（血受气的影响而生病，是气所化生，故称“所生病”。足少阳胆经血少气多，这是人体的常数。也有不同于常数的情况，《灵枢经》说：足少阳经上部，血气旺盛则鬓发美且长，血多气少则胡须美但短，血少气多则胡须少，血气皆少则无胡须。若遇寒温失调，则容易发生痹症、骨痛、指甲枯槁等。足少阳经下部，血气旺盛，则小腿毛发美且长，外踝丰满；血多气少，则小腿毛发美但短，外踝皮肤坚硬厚实；血少气多，则小腿毛发少，外踝皮肤薄而软；血气皆少，则无毛，外踝瘦削无肉。又说：鬓发和胡须极盛者，说明少阳经血多。由此可知足少阳经血气的多少状况）。头痛、头角及下颌疼痛（角颔，指耳下曲角处的下颌。因其经脉下行经过颊车，故出现此类病症）。目外眦疼痛，缺盆中肿痛，腋下肿，马刀挟瘿（马刀挟瘿，据《灵枢经》记载：那种痈肿坚硬而不溃破的，称为马刀挟瘿）。汗出、战栗恶寒（因寒邪客居经脉，经脉虚弱，则邪气亢盛，故表现为战栗恶寒）。疟疾（疟疾是寒热往来的疾病，此处指中阳之疟，寒热症状均不严重）。胸胁、肋部、大腿外侧、膝盖外侧的小腿、绝骨、外踝前以及各个关节都疼痛，小指和次趾功能丧失。脉象方面，实证表现为人迎脉搏动比寸口大一倍；虚证表现为人迎脉搏动反而小于寸口。
足少阳胆经的别络，名叫光明，距离外踝五寸处，别行走向足厥阴肝经，向下联络足背。实证表现为厥逆，虚证表现为痿弱不用，坐起困难，治疗应取该别络穴位。
足少阳胆经的筋脉，起始于第四趾上方，结聚于外踝，沿小腿外侧廉，结聚于膝外侧廉。其分支另起于外辅骨上方，走于大腿前方，结聚于伏兔穴上方；另一分支结聚于尻部。其直行者，向上乘夹季胁，向上走于腋前廉，挟持胸乳部位，结聚于缺盆。其直行者，向上出于腋下，贯穿缺盆，出于太阳经之前，沿耳后上行至额角，交会于头顶，向下走于下颌上方。其分支，结聚于目外眦，作为外维筋。其病症包括：第四趾及次趾牵引性转筋，牵引膝外侧转筋，膝关节不可屈伸；筋脉拘急向前牵引大腿，向后牵引尻部；若向上乘夹季胁则痛，向上牵引缺盆、胸乳、颈部。若颈维筋拘急，左侧受伤影响右侧，导致右眼无法睁开，病气上过右角，并与跷脉并行，左络脉连系于右，所以损伤右角会导致右足不能使用，这叫做维筋相交。治疗采用燔针劫刺法，以病情好转为度，以痛点为腧穴，病名叫做孟春痹。
邪气客居于足少阳胆经的络脉，使人胁痛，呼吸不畅，咳嗽并出汗。针刺足小趾和次趾爪甲上与肉交界处各一针，呼吸不畅立即缓解，出汗立即停止。咳嗽者，保暖衣物饮食一天即可痊愈。病在左侧刺右侧，病在右侧刺左侧，病立愈。若不愈，再次按此法针刺。
邪气客居于足少阳胆经的络脉，使人枢中（关节枢纽处）疼痛，大腿无法抬起。用毫针刺枢中穴，寒证久留针，以月亮盈亏变化天数为准，病立愈。热证先见胸胁痛，手足躁扰，针刺足少阳经，补足太阴经。病势严重的采用五十九刺法。热病先出现眩晕冒昧而后发热胸胁满闷，针刺足少阴、足少阳经。
足少阳胆脉从头走足，长度八尺，左右共一丈六尺。共有八十六个穴位。

The meridian of Foot-Shaoyang Gallbladder originates at the outer canthus (Shaozhuo, GB1), ascends to the frontal angle, descends behind the ear, and follows the neck, running anterior to the meridian of Hand-Shaoyang Sanjiao. Upon reaching the shoulder, it turns and emerges posterior to the Hand-Shaoyang Sanjiao meridian (Note: The text clarifies that Foot-Shaoyang runs anterior to Hand-Shaoyang along the neck, but at the shoulder, Hand-Shaoyang is posterior, meaning Foot-Shaoyang is anterior). It enters the clavicular fossa (Quepen, LI15). A branch enters the ear from behind the ear, emerges anterior to the ear, reaches the lateral canthus, descends to Daying (ST4), meets the Hand-Shaoyang Sanjiao meridian, ascends to the infraorbital region, descends to Jiache (ST6), then goes down the neck to converge with the main trunk in the clavicular fossa. From there, it descends into the chest, pierces the diaphragm, connects with the Liver (as the Liver is the support for the Gallbladder, the Gallbladder meridian links to the Liver), and belongs to the Gallbladder (Foot-Shaoyang is the meridian of the Gallbladder, so its vessel belongs to the Gallbladder organ). It runs along the interior of the hypochondrium, emerges at Qichong (ST30) (located one cun below the umbilicus, on both sides of the pubic bone, above the inguinal ligament, in the pulsation of the femoral artery), surrounds the pubic hair margin, and transversely enters the hip joint depression (Huantiao, GB30). The straight branch descends from the clavicular fossa to the axilla, passes along the chest through the costal margin (ribs are called Lei; the end of the ribs is called Jixie), converges with the hip joint depression, and descends along the lateral aspect of the thigh (Bi Yang, i.e., the lateral thigh), emerges at the lateral side of the knee (Yanglingquan, GB34), descends anterior to the fibula (Fugu refers to the fibula assisting the tibia, located outside the tibia), goes straight down to the end of the absolute bone (Yangfu, GB38, located at the end of this absolute bone), emerges anterior to the lateral malleolus (Qiuxu, GB40), follows the dorsum of the foot, and emerges at the tip of the fourth toe (the tip of the fourth toe is where Qiaoyin is located; *Suwen* states: "The Qi of Shaoyang begins at Qiaoyin"). Another branch diverges from the dorsum of the foot, enters between the big toe, follows the medial side of the bifurcation of the big toe, emerges at its tip, loops around to penetrate the nail bed, and emerges at the pubic hair (Foot-Shaoyang Gallbladder meridian intersects with Foot-Jueyin Liver meridian here).
When the meridian undergoes pathological changes ("Is-Dong" diseases, as Foot-Shaoyang typically has less blood and more Qi, if Qi is diseased first, it is called Is-Dong), symptoms include bitter taste in the mouth (*Suwen* states: "Bitter taste in the mouth is named Dan-Dan [Gallbladder Heat]. This person usually hesitates in decision-making, leading to Gallbladder deficiency, causing Qi to overflow upward, resulting in a bitter taste. Treatment should use the Front-Mu and Back-Shu points of the Gallbladder"). Frequent sighing (*Lingshu* states: "Worry and thought cause tension in the Heart vessels; tension in Heart vessels constrains the Qi pathway; constraint leads to obstruction, so one sighs to release the Qi"). Pain in the heart and hypochondrium (*Suwen* mentions pain in the heart and hypochondrium refers to excess in Shaoyang. Excess is the exterior manifestation of the Heart. In the ninth month, Yang Qi is abundant and Yin Qi declines, hence the term heart-hypochondriac pain). Inability to turn or roll over (*Suwen* states: "Inability to reverse sides is because in the ninth month, Yin Qi stores, and all things remain still, hence inability to reverse sides"). Severe cases present with a face covered like dust (face like fine dust, having a dusty color), body lacking luster and moisture, and heat on the lateral aspect of the foot, known as Yang-Jue (Yang Reversal).
This meridian governs the bones. Diseases generated by this meridian ("Suo-Sheng-Bing", blood is diseased due to Qi, thus it is what Qi generates. Foot-Shaoyang has little blood and much Qi, which is the constant state of humans. However, there are variations. *Lingshu* states: "At the upper part of Foot-Shaoyang, abundant blood and Qi result in beautiful long sideburns; much blood and little Qi result in beautiful short beards; little blood and much Qi result in few beards; both scarce result in no beard. Imbalance of cold and warmth leads to Bi syndrome, bone pain, and withered nails. At the lower part of Foot-Shaoyang, abundant blood and Qi result in beautiful long leg hair and full lateral malleoli; much blood and little Qi result in beautiful short leg hair and firm, thick skin at the lateral malleoli; little blood and much Qi result in sparse leg hair and thin, soft skin at the lateral malleoli; both scarce result in no hair and emaciated flesh at the lateral malleoli." It is also said that those with extremely lush sideburns and beards have abundant blood in Shaoyang. Thus, the abundance or scarcity of blood and Qi in Foot-Shaoyang can be known.) Symptoms include headache, pain at the temporal angle and mandible (Jiao-Han refers to the mandible at the curved angle below the ear; since the meridian passes through Jiache, such diseases occur). Pain at the outer canthus, swelling and pain in the clavicular fossa, axillary swelling, "Ma-Dao Jia-Ying" (Marine Knife and Clinging Goiter; *Lingshu* states: "Abscesses that are hard and do not ulcerate are called Marine Knife and Clinging Goiter"). Sweating with chills (Cold pathogen lodges in the meridian; when the meridian is deficient, the pathogen becomes excessive, hence chills with trembling). Malaria (Malaria is a disease of alternating cold and heat; referring to Zhong-Yang Malaria, where cold and heat are not severe). Pain in the chest, hypochondrium, ribs, lateral thigh, lateral knee, lower leg, end of the absolute bone, anterior to the lateral malleolus, and all joints; dysfunction of the fourth and fifth toes. In excess patterns, the Renying pulse is one times larger than the Cunkou pulse; in deficiency patterns, the Renying pulse is smaller than the Cunkou pulse.
The Luo-connecting vessel of Foot-Shaoyang is named Guangming (GB37), located five cun above the ankle, diverging to connect with Jueyin, and descending to link with the dorsum of the foot. In excess, there is Jue (reversal); in deficiency, there is Wei (atrophy/weakness), inability to sit up and stand. Treatment involves needling the point where it diverges.
The sinews of Foot-Shaoyang originate above the fourth toe, knot at the lateral malleolus, follow the lateral aspect of the calf, and knot at the lateral aspect of the knee. A branch arises from above the lateral fibula, travels anterior to the thigh, knots above Futu (ST32); another branch knots at the sacrum. The straight branch ascends through the costal margin, moves anteriorly to the axilla, clamps the chest and breast, and knots at the clavicular fossa. Another straight branch ascends out of the axilla, penetrates the clavicular fossa, emerges anterior to Taiyang, follows behind the ear to the frontal angle, crosses the vertex, descends to the mandible. A branch knots at the outer canthus, serving as the external suspension. Pathological manifestations include spasmodic contraction of the fourth and fifth toes,牵引 (pulling) to spasmodic contraction of the lateral knee, inability to flex or extend the knee; tendon stiffness pulling forward to the thigh and backward to the sacrum; if ascending to clamp the costal margin, pain occurs; if ascending to pull the clavicular fossa, chest, breast, and neck. If the suspending tendon is stiff, injury on the left affects the right, causing the right eye to fail to open; the pathogenic Qi ascends to the right corner, runs with the Qiao meridians, and the left collateral connects to the right. Thus, injury to the right corner results in non-function of the right foot, termed "Wei-Jin Xiang-Jiao" (Crossed Suspension Sinew). Treatment uses burning needle rapid puncture, taking improvement as the criterion, and using painful points as Shu points. This condition is named Meng-Chun Bi (Early Spring Bi Syndrome).
When evil qi lodges in the Luo-connecting vessel of Foot-Shaoyang, it causes hypochondriac pain, dyspnea, cough with sweating. Needle each of the points at the junction of the nail and flesh on the fourth and fifth toes once. Dyspnea resolves immediately, sweating stops immediately. For cough, warm clothing and diet for one day will resolve it. Treat left-sided disease by needling the right, and right-sided disease by needling the left. Disease resolves immediately. If not resolved, repeat needling according to this method.
When evil qi lodges in the Luo-connecting vessel of Foot-Shaoyang, it causes pain in the pivot (joint) and inability to lift the thigh. Use a filiform needle to shi Shuzhong (pivot point). For cold patterns, retain the needle for a long time, counting by the days of the lunar cycle until resolution. For heat patterns presenting initially with chest/hypochondriac pain and restlessness of hands and feet, needle Foot-Shaoyang and tonify Foot-Taiyin. For severe cases, use the Fifty-Nine Needles technique. For heat diseases presenting initially with dizziness, vertigo, followed by fever and chest/hypochondriac fullness, needle Foot-Shaoyin and Foot-Shaoyang.
The meridian of Foot-Shaoyang Gallbladder runs from head to foot, measuring eight chi in length, totaling one zhang six chi for both sides. There are eighty-six acupoints in total.
