（臂下胁上际也）属手厥阴心包经（《灵枢》曰∶手厥阴之脉，其支者，循胸出胁，下腋
三寸，上抵腋下，是动则病腋肿。又曰∶手心主之正别，下渊腋三寸，入胸中。又曰∶手心主之筋，结腋下。
又曰∶腋下三寸，手心主也，其名天池）。又属手太阴肺经、少阴心经（《灵枢》曰∶手太阴之脉，从肺系横
出腋下。又曰∶手太阴之正，别入渊腋少阴之前。又曰∶腋下动脉，臂太阴也，名曰天府。暴瘅内逆，肝肺相
搏，血溢鼻口，取天府。又曰∶手少阴之脉，从心系却上肺，下出腋下。又曰∶手少阴之正，别入于渊腋两
筋之间，属于心）。又属足厥阴肝经、太阴脾之大络。（《灵枢》曰∶肝有邪，其气留于两腋。又曰∶脾之大
络，名曰大包，出渊腋下三寸，布胸胁，实则腹尽痛，虚则百节尽皆纵。此脉若罗络之血者皆取之。沈承之
曰∶腋间属手足厥阴心包、肝经，腋前属手太阴肺经，腋后属手少阴之经，腋下属足厥阴肝经，下六寸，属足
太阴脾之大络）。兼属手太阳小肠经、足少阳胆经（《灵枢》曰∶手太阳之筋，结于腋下，其病腋下痛。又曰∶
足少阳之脉，从缺盆下腋，所生病者腋中肿。又曰∶足少阳之筋，从季胁上走腋前廉。朱丹溪曰∶手足厥阴
合生见证，曰腋肿，手厥阴、足少阳也）。
（腋窝是手臂下方与胁肋上方的交界处。）它归属于手厥阴心包经（《灵枢》记载：手厥阴经脉，其分支，沿着胸部走出胁部，向下至腋下三寸，向上抵达腋下，发生变动时会出现腋窝肿胀。又说：手厥阴的正别脉，向下至渊腋穴下三寸，进入胸中。又说：手厥阴的筋，结聚于腋下。又说：腋下三寸处，属于手厥阴经，穴位名称是天池）。又归属于手太阴肺经、手少阴心经（《灵枢》记载：手太阴经脉，从肺系横向出于腋下。又说：手太阴的正别脉，别行进入渊腋穴前方、手少阴经之前。又说：腋下的动脉，属于手太阴经，名称叫天府穴。突发热病且气逆内攻，肝肺之气相互搏结，血液从鼻口溢出，应取天府穴。又说：手少阴经脉，从心系退后上行至肺，向下出于腋下。又说：手少阴的正别脉，别行进入渊腋两筋之间，归属于心）。又归属于足厥阴肝经、足太阴脾经的大络（《灵枢》记载：肝脏有邪气，其气停留于两侧腋窝。又说：脾经的大络，名称叫大包穴，出于渊腋穴下三寸，散布于胸胁部，实证则腹部全部疼痛，虚证则全身关节松弛无力。这条脉络如同网罗般的血络都应取治。沈承之说：腋窝中间属于手足厥阴的心包经和肝经，腋窝前部属于手太阴肺经，腋窝后部属于手少阴心经，腋窝下部属于足厥阴肝经，再向下六寸，属于足太阴脾经的大络）。同时兼属手太阳小肠经、足少阳胆经（《灵枢》记载：手太阳的筋，结聚于腋下，病症表现为腋窝疼痛。又说：足少阳经脉，从缺盆向下进入腋窝，所发生的疾病包括腋窝肿胀。又说：足少阳的筋，从季胁向上走向腋窝前缘。朱丹溪说：手足厥阴经合而生出的见证，称为腋肿，涉及手厥阴经和足少阳经）。
(The axilla is the junction between the lower arm and the upper lateral chest.) It belongs to the Pericardium Meridian of Hand-Jueyin (The *Ling Shu* states: The branch of the Pericardium Meridian of Hand-Jueyin follows the chest, emerges from the hypochondrium, descends three cun below the axilla, and ascends to reach the axilla. When this meridian is in a state of abnormal movement, it causes swelling in the axilla. It also states: The regular divergent branch of the Pericardium enters three cun below the Yuanye [Yuan Ye] acupoint, entering the chest cavity. Furthermore, the sinews of the Pericardium knot at the axilla. Additionally, the area three cun below the axilla belongs to the Pericardium Meridian, and its acupoint is named Tianchi [Heavenly Pool]). It also belongs to the Lung Meridian of Hand-Taiyin and the Heart Meridian of Hand-Shaoyin (The *Ling Shu* states: The Lung Meridian of Hand-Taiyin emerges horizontally from the lung system into the axilla. It also states: The regular divergent branch of the Lung Meridian enters anterior to the Yuanye acupoint and the Heart Meridian. Moreover, the arterial pulse in the axilla belongs to the Lung Meridian of Hand-Taiyin, named Tianfu [Heavenly Mansion]. In cases of sudden heat disease with internal reversal of qi, where Liver and Lung qi clash causing blood to溢 from the nose and mouth, Tianfu should be selected. It further states: The Heart Meridian of Hand-Shaoyin originates from the heart system, moves posteriorly and ascends to the lung, then emerges downward from the axilla. It also states: The regular divergent branch of the Heart Meridian enters between the two sinews at the Yuanye region and connects to the Heart). It additionally belongs to the Liver Meridian of Foot-Jueyin and the Large Luo Vessel of the Spleen Meridian of Foot-Taiyin (The *Ling Shu* states: When pathogenic factors affect the liver, their qi remains in both axillae. It also states: The Large Luo Vessel of the Spleen is named Dabao [Great Wrap], emerging three cun below the Yuanye acupoint, spreading over the chest and hypochondrium. In excess conditions, there is pain throughout the abdomen; in deficiency conditions, all joints become flaccid and weak. These vessels, resembling a network of collateral blood vessels, should all be treated. Shen Chengzhi stated: The center of the axilla belongs to the Pericardium and Liver meridians of Hand- and Foot-Jueyin; the anterior aspect of the axilla belongs to the Lung Meridian of Hand-Taiyin; the posterior aspect belongs to the Heart Meridian of Hand-Shaoyin; the inferior aspect belongs to the Liver Meridian of Foot-Jueyin; six cun further down belongs to the Large Luo Vessel of the Spleen Meridian of Foot-Taiyin). It simultaneously involves the Small Intestine Meridian of Hand-Taiyang and the Gallbladder Meridian of Foot-Shaoyang (The *Ling Shu* states: The sinews of the Small Intestine Meridian of Hand-Taiyang knot at the axilla, with symptoms including axillary pain. It also states: The Gallbladder Meridian of Foot-Shaoyang descends from the Clavicle fossa into the axilla, and diseases arising from this meridian include swelling in the axilla. Furthermore, the sinews of the Gallbladder Meridian ascend from the costal margin toward the anterior edge of the axilla. Zhu Danxi stated: The manifestations generated by the convergence of the Hand- and Foot-Jueyin meridians are called axillary swelling, involving the Pericardium Meridian of Hand-Jueyin and the Gallbladder Meridian of Foot-Shaoyang).
