强进食。必生长其肉。又宽缓其带。散披其发。扶大杖。着重履。以缓步之。盖不太劳动。以肾气之衰弱也。
余经不言此法。而唯肾经详言者。以肾经属水。为身之本。而病患多犯其戒。故独言之详。张云。生肉浓味也。
味浓所以补精。志云。生、当作牲。周礼云。始养之谓。畜将用之谓牲。又牛羊豕曰三牲。夫羊为火畜。牛为

心包络 甲乙、铜人无此三字。发挥。络一字无。张云。心主者。心之所主也。心本手少阴。而
复有手厥阴者。心包络之经也。如邪客篇曰。心者五脏六腑之大主也。诸邪之在心者。皆在心之包络。包络者。
心主之脉也。其脉之出入屈折。行之疾徐。皆如手少阴心主之脉行也。故曰。心主手厥阴心包络之脉。续医说
孙、景思医论云。或谓心包络乃胸中之脂膜。或又谓之裹心之肉。皆非也。乃裹心之黄脂膜。包于心外。似脂
非脂。似肉非肉。外则有细筋膜如系。与心肺相连者。此则是心包络也。余谓诸兽之内景。大概亦与人相同。
观其心形。亦略可见矣。
介按、唐容川云。心之上面。周遭有夹膜裹之。即包络也。包络上连肺系。由肺系连及于胸内之四面。
皆是油膜。
又下为网油膜。所谓膜者。皆三焦也。三焦与包络相通。其迹如此。故包络之脉。下膈历三焦也。
出属心包络（止）历络三 张云。心包络。包心之膜络也。包络为心主之外卫。三 为脏腑之
外卫。故为表里而相络。诸经皆无历字。独此有之。盖指上中下而言。上即膻中。中即中脘。下即脐下。故任
脉之阴交穴。为三 募也。

是主脉所生病者 甲乙注。脉、一作心包络。铜人作
心包脉。志云。心主血。而包络代君行令。故主脉。
起于小指次指之端（止）上贯肘 两指。发挥作次指。滑氏云。臂骨尽处为腕。 尽处为肘。手少
阳起小指次指端关冲穴。上出次指之间。历液门、中渚。循手表腕之阳池。出臂外两骨之间。循外关、支沟、
会宗、三阳络、四渎。乃上贯肘抵天井穴。介按、从关上行。手小指次指歧骨间陷中。握拳取之。即液门穴也。
由此上行一寸。陷中。是中渚穴也。由四指本节直上行。手表腕上陷中。即阳池穴也。再上行手腕后二寸。两
骨间陷中。是外关穴也。由此上行一寸。两骨间陷中。即支沟穴也。从此外开一寸。即会宗穴也。由此内斜上

起于目锐 上抵头角 下耳后 滑氏云。足少阳经起目锐 之瞳子 。于是循听会、客主人。
上抵头角。循颔厌。下悬颅、悬厘。由悬厘外循耳上发际。至曲鬓、率谷。由率谷外折下耳后。循天冲、浮白、
其分支（止）夹脊内侧。《甲乙经》注解说：一作“髋”。《缪刺论》王注。《铜人腧穴针灸图经发挥》作“胂”。滑寿说：膂肉叫作胂，即夹脊的肉。其分支是夹脊两旁第三行、相距各三寸的诸穴位，从天柱穴向下，从肩内左右分开，下行贯穿夹脊肉，经过附分、魄户、膏肓、神堂、膈关、魂门、阳纲、意舍、胃仓、肓门、志室、胞肓、秩边等穴，下行经过尻臀，过髀枢（止）。
丹波元介按：膀胱经穴位，自大杼穴别出经脉。其分支从肩膊内循行，沿第二椎下项内廉两旁，距脊中各三寸半，正坐取之，即是附分穴。由附分至秩边穴，共计十四穴，左右依次而下，共二十八穴。
过髀枢（止），合入腘中。《甲乙经》、《铜人》无“从”字。滑寿说：股外为髀，捷骨之下为髀枢，循髀外后廉，在髀枢之内，本经承扶穴外一寸五分之间，而下与前之入腘中者相合。
以下贯腨内（止）至小指外侧。马云说：“腨”、“腨”同义。滑寿说：“腨”，即腓肠肌。下行循行合阳穴，下行贯入腨内，经过承筋、承山、飞阳、跗阳，出于外踝后的昆仑、仆参、申脉、金门，循行京骨、束骨、通谷，至小指外侧端的至阴穴，以交于足少阴肾经。杨玄操说：腓骨之下为立骨。左右各有内外踝骨，共四个。踝骨之后，各有京骨，左右共两个。张景岳说：小指本节后，大骨叫作京骨。
髀不可以曲伸。《甲乙经》无“髀”字，似是。张景岳以髀为髀枢，不知是否准确。
踝厥。张景岳说：足太阳脉出外踝之后，筋结于外踝。
是主筋所生病者。张景岳说：周身筋脉，惟足太阳经最多且巨。其下者结于踵、结于腨、结于腘、结于臀；其上者挟腰脊、络肩项，上头为目上纲，下结于腘。所以凡是出现挛急、弛缓、角弓反张、睁眼等症状，都是足太阳经水亏所致，属于主筋所生的疾病。汪昂说：主筋，含义不详。按：太阳病多表现为痉急如上述症状，都是风邪伤及筋脉。
痔、疟、狂、癫疾。张景岳说：脉入肛门故生痔，经属表故生疟，邪入于阳，故生狂癫疾。马云说：《刺疟篇》有太阳之疟，《癫狂篇》二十二处有刺太阳经的记载。
项痛。《甲乙经》项下有“颈间”二字。
邪走足心。《甲乙经》、《铜人》、《发挥》，“走”作“趣”。马云作“趋”。滑寿说：趣，向也。足少阴肾经起于小趾之下，斜向足心的涌泉穴，在足心陷中，屈足卷指宛宛中。马云说：邪，斜同义。
出于然谷之下（止）出内踝下廉。《脉经》、《千金方》，“谷”作“骨”。滑寿说：由涌泉转出足内踝然谷穴，下循内踝后太溪穴，别入踝中之太钟、照海、水泉，乃折自太钟之外，上循内踝，行厥阴、太阴之后，经复溜、交信，过三阴交，上腨内，循筑宾，出内踝下廉，抵阴谷也。
丹波元介按：足少阴肾经的涌泉穴，在足心陷中，伸腿屈足卷指宛宛中。从涌泉上行足内踝前，起大骨陷中，即然谷穴也。又行足内踝后五分跟骨上动脉陷中，即太溪穴也。足跟后跟中，大骨上两筋间，即太钟穴也。再从太钟行太溪下一寸，内踝下，即水泉穴也。足内踝下四分前后，有筋，上有踝骨，下有软骨之中陷中，即照海穴也。从照海行足内踝后，除踝上二寸许，前旁骨陷中，即复溜穴也。从此斜外上行复溜穴之后，二寸许，后旁筋，即交信穴也。再斜外上行过三阴交穴，上腿肚中，即筑宾穴也。再上行膝下，内辅骨后，大筋下，小筋上，按之应手，屈膝得之，即阴谷也。
上股内后廉贯脊属肾络膀胱。滑寿说：出阴谷，上股内后廉，贯脊会脊之长强穴，还出于前，循横骨、大赫、气穴、四满、中注、肓俞。当肓俞之所，脐之左右属肾，下脐下，过关元、中极，而络膀胱也。
其直行者（止）挟舌本。《甲乙经》注一本云：从横骨中挟脐循复里，上行而入肺。滑寿说：其直行者从肓俞属肾处，上行循商曲、石关、阴都、通谷诸穴，贯肝上，循幽门、上膈，历步廊，入肺中，循神封、灵墟、神藏、或中俞腑，而上循喉咙，并人迎，挟舌本而终也。张景岳说：按足少阴一经，考之本篇及经别、经筋等篇，皆言由脊里上注心肺，而散于胸中。惟《骨空论》曰：冲脉者，起于气街，并少阴之经，侠脐上行至胸中而散。故《甲乙经》于俞府、神藏、灵墟、神封、步廊等穴，皆云足少阴脉气所发；幽门、通谷、阴都、石关、商曲、肓俞、中注、四满、气穴、大赫、横骨十一穴，皆云冲脉足少阴之会。故滑氏之注如此，实本于《甲乙》、《铜人》诸书，而《甲乙》等书，实本之《骨空论》也。
丹波元介按：从横骨上行一寸，中行旁开五分，即大赫穴也。再上行一寸，中行旁开五分，即气穴穴也。再上行一寸，中行旁开五分，即四满穴也。再上行一寸，中行旁开五分，即中注穴也。再上行一寸，直脐旁去五分，即肓俞穴也。再上行二寸，中行旁开五分，即商曲穴也。再上行一寸，中行旁开五分，即石关穴也。再上行一寸，中行旁开五分，即阴都穴也。再上行一寸，陷中，中行旁开五分，即通谷穴也。再上行一寸，陷中，中行旁开五分，即幽门穴也。再上行一寸、陷中，中行旁开二寸，仰而取之，即步廊穴也。再上行一寸六分，中行旁开二寸，即神封穴也。再上行一寸六分，即灵墟穴也。再上一寸六分，即神藏穴也。再上行一寸六分，即俞府穴也。从俞府上行巨骨，下侠任脉之璇玑，中行旁开二寸，陷中，仰而取之，即俞府穴也。（注：此处原文可能有误，通常俞府在最上方，此处依原文翻译）
其分支（止）注胸中。滑寿说：两乳间为胸中，支者自神藏，别出绕心，注胸之膻中，以交于手厥阴心包经也。
病饥不欲食。马云说：盖虚火盛则饥，而不欲食者，脾气弱也。张景岳说：肾虽阴脏，元阳所居，水中有火，为脾胃之母，阴动则阳衰，阳衰则脾困，故病虽饥，而不欲食。
面如漆柴。《甲乙经》、《铜人》，作面黑如炭色。《铜人》注云：一作地色。《素问》曰：所谓面黑如地者，和气内夺，故变于色也。（案出《脉解篇》）《发挥》作地色，本之也。马云说：漆则肾之色黑者，形于外而如漆柴，则肾主骨者瘦矣。张景岳说：水色黑，阴邪色见于面，故如漆。肾藏精，精衰则枯，故如柴。杨玄操《二十四难注》云：漆柴者，恒山苗也。其草色黄黑无润泽，故以为喻。简案：据杨说漆即蜀漆，然本草中无所考。
咳唾则有血。马云说：脉入肺中则为咳，而唾中有血，则肾主有损。
喝喝而喘。《甲乙经》注：一作喉鸣。《铜人》亦作喉鸣而喘。
坐而欲起。马云说：阴虚不能宁静。
目视不明。马云说：水亏肝弱。张景岳说：目之明在瞳子，瞳子者，骨之精也。肾气内夺，则目眦如无所见。故凡目多昏黑者，必真水亏于肾也。
心如悬若饥状。张景岳说：心肾不交，则精神离散，故心如悬。阴虚则内热，故常若饥状。
善恐。马云说：《阴阳应象大论》曰：肾在志为恐。张景岳说：肾气怯，故惕惕如人将捕之。《甲乙经》无“气不足以下十四字”。
黄疸、肠澼。马云说：五疸有女劳疸。《通评虚实论》、《大奇论》，皆有肠澼。张景岳说：阴虚阳实，故为黄疸。肾开窍于二阴，故为肠澼。
痿厥、嗜卧。《铜人》注云：人冒暑热之毒舍于肾，肾乃水脏也。水不胜火，则骨与髓虚，故足不任身，而痿厥生焉。痿则无力，故嗜卧也。马云说：脉有骨痿，义见《痿论》。张景岳说：嗜卧者，多阴少阳，精神匮也。《逆调论》曰：肾者水脏，主津液，主卧与喘也。
灸则强食生肉（止）重履而步。灸则以下十六字，《甲乙经》移于足下热而痛下。马云说：如灸者则当勉强进食，必生长其肉，又宽缓其带，散披其发，扶大杖，着重履，以缓步之。盖不太劳动，以肾气之衰弱也。余经不言此法，而唯肾经详言者，以肾经属水，为身之本，而病患多犯其戒，故独言之详。张景岳说：生肉浓味也。味浓所以补精。志云：生，当作牲。《周礼》云：始养之谓畜，将用之谓牲。又牛羊豕曰三牲。夫羊为火畜，牛为土畜，豕为水畜。其性躁善奔，强食牲肉，以助肾气上升，而与火土之相合也。缓带者，取其伸舒也。夫肾脏之精，奉心神化赤而为血，发乃血之余也。披发者，使神气之下交也。大杖重履者，运筋骨之气也。夫阴阳之气，有厥于臂者，有厥于腘者，有厥于踝者，有厥于骨者。此章论少阴之气厥逆于下，而曰强食牲肉，曰缓带披发，盖少阴为阴阳生气之原也。简案：重，诸家无解，当读如字。
心包络。《甲乙经》、《铜人》无此三字。《发挥》，“络”一字无。张景岳说：心主者，心之所主也。心本手少阴，而复有手厥阴者，心包络之经也。如《邪客篇》曰：心者五脏六腑之大主也，诸邪之在心者，皆在心之包络。包络者，心主之脉也。其脉之出入屈折，行之疾徐，皆如手少阴心主之脉行也。故曰：心主手厥阴心包络之脉。续医说孙、景思医论云：或谓心包络乃胸中之脂膜，或又谓之裹心之肉，皆非也。乃裹心之黄脂膜，包于心外，似脂非脂，似肉非肉，外则有细筋膜如系，与心肺相连者，此则是心包络也。余谓诸兽之内景，大概亦与人相同，观其心形，亦略可见矣。
丹波元介按：唐容川云：心之上面，周遭有夹膜裹之，即包络也。包络上连肺系，由肺系连及于胸内之四面，皆是油膜。又下为网油膜，所谓膜者，皆三焦也。三焦与包络相通，其迹如此，故包络之脉，下膈历三焦也。
出属心包络（止）历络三焦。张景岳说：心包络，包心之膜络也。包络为心主之外卫，三焦为脏腑之外卫，故为表里而相络。诸经皆无“历”字，独此有之，盖指上中下而言。上即膻中，中即中脘，下即脐下。故任脉之阴交穴，为三焦募也。
其分支（止）肘中。滑寿说：胁上际为腋，自属心包，上循胸出胁下腋三寸天池穴，上行抵腋下，下循臑内之天泉穴，以介乎太阴、少阴两经之中间，入肘中之曲泽也。
下臂（止）出其端。滑寿说：由肘中下臂，行臂两筋之间，循郄门、间使、内关、大陵，入掌中劳宫穴，循中指指出其端之中冲云。
丹波元介按：行臂两筋之间，即是曲泽穴。由此下行掌后，去腕五寸，即郄门穴也。再下行掌后，去腕三寸，两筋间陷中，即间使穴也。从此下行掌后，去腕二寸，两筋间，内关穴也。再下行掌后，骨下横纹中，两筋间陷中，大陵穴也。由此下行掌中央动脉，屈无名指取之，即劳宫穴也。从劳宫下行手中指之端，去爪甲角，如韭叶许陷中，即中冲穴也。
其分支（止）出其端。滑寿说：小指次指无名指也。自小指逆数之，则为次指。云支别者，自掌中劳宫穴别行，循小指次指出其端，而交于手少阳三焦经也。
心中憺憺。《铜人》作澹澹。注：席延赏云：淡淡，水摇也。张景岳说：憺，音淡，动而不宁貌。
面赤目黄。张景岳说：心之华在面，目者心之使，故病则面赤目黄。
喜笑不休。马云说：心在声为笑。
是主脉所生病者。《甲乙经》注：脉，一作心包络。《铜人》作心包脉。汪昂说：心主血，而包络代君行令，故主脉。
起于小指次指之端（止）上贯肘。两指，《发挥》作次指。滑寿说：臂骨尽处为腕，肘尽处为肘。手少阳三焦经起小指次指端关冲穴，上出次指之间，历液门、中渚，循手表腕之阳池，出臂外两骨之间，循外关、支沟、会宗、三阳络、四渎，乃上贯肘抵天井穴。介按：从关上行，手小指次指歧骨间陷中，握拳取之，即液门穴也。由此上行一寸，陷中，是中渚穴也。由四指本节直上行，手表腕上陷中，即阳池穴也。再上行手腕后二寸，两骨间陷中，是外关穴也。由此上行一寸，两骨间陷中，即支沟穴也。从此外开一寸，即会宗穴也。由此内斜上行一寸，臂上大交脉，三阳络穴也。再上行肘前五寸，外廉陷中，四渎穴也。从四渎斜外上行，肘外大骨尖后，肘上一寸两筋又骨罅中，屈肘拱胸取之，即天井穴也。
循臑外（止）循属三焦。下循字，《甲乙经》、《铜人》作偏。张景岳说：上贯肘之天井，循臑外行手太阳之前，手阳明之后，历清冷渊、消烁、臑会，上肩髃，过足少阳之肩井，自天髎而交，出足少阳之后也。其内行者，入缺盆，复由足阳明之外，下布膻中，散络心包，相为表里，乃自上焦下膈，循中焦下行，并足太阳之正，入络膀胱，以约下焦。故足太阳经委阳穴，为三焦下辅腧也。
其分支（止）至耳。张景岳说：其支行于外者，自膻中上行出缺盆，循天髎，上项，会于督脉之大椎、天牖，系耳后之翳风、颅息，出耳上角之角孙，过足少阳之悬厘、颔厌，下行耳颊至䪼，会于手太阳颧之分。䪼，音拙，目下也。
其分支（止）至目锐眦。出走耳前，以下十一字，《发挥》无。张景岳说：此支从耳后翳风入耳中，过手太阳之听宫，出走耳前之耳门，过足少阳之客主人，交颊，循和髎，上丝竹空，至目锐眦，会于瞳子髎穴。手少阳经止于此，而接乎足少阳经也。
浑浑暍暍。马云说：浑浑然，暍暍然，甚觉不听也。张景岳说：不明貌。简案：《明堂灸经》作“恽恽恽恽”。《孙子兵势篇》：浑浑沌沌，形圆而不可败，即混沌也。
是主气所生病者。张景岳说：三焦为水渎之腑，水必由于气也。
汗出。张景岳说：三焦出气，以温肌肉，充皮肤，故为汗出。其他诸病，皆本经之脉所及。
起于目锐眦上抵头角下耳后。滑寿说：足少阳胆经起目锐眦之瞳子髎，于是循听会、客主人，上抵头角，循颔厌，下悬颅、悬厘，由悬厘外循耳上发际，至曲鬓、率谷，由率谷外折下耳后，循天冲、浮白、
Its branch (ends) runs inside the spine. The commentary in *Jia Yi Jing* states: alternatively written as "Kuan" (hip). Wang's commentary on *Miao Ci Lun*. *Tong Ren Fu Hui* writes it as "Shen". Hua Shi says: "Shen" refers to the muscles of the spine, i.e., the flesh flanking the spine. This branch consists of various acupoints located three cun apart on both sides of the third line flanking the spine, descending from Tian Zhu (DU16), diverging left and right from within the shoulder, running down through the paraspinal muscles, passing through Fu Fen (BL48), Po Hu (BL48), Gao Huang (BL43), Shen Tang (BL44), Ge Guan (BL47), Hun Men (BL47), Yang Gang (D49), Yi She (BL45), Wei Cang (BL45), Huang Men (BL52), Zhi Shi (BL52), Bao Huang (BL54), and Zhi Bian (BL54). It descends past the sacrum and buttocks, crossing the Bi Shu (pivot of the thigh).
Danbo Yuanjie notes: The Bladder Meridian points diverge from Da Shu (BL11). Its branch runs along the interior of the shoulder blades, following the inner edge of the neck below the second thoracic vertebra, three and a half cun lateral to the midline of the spine. When sitting upright, this is the point Fu Fen (BL48). From Fu Fen to Zhi Bian (BL54), there are fourteen points in total; with bilateral symmetry, this amounts to twenty-eight points.
Crossing the Bi Shu (pivot of the thigh) (ends), it joins the Popliteal Fossa (Yu Zhong). *Jia Yi Jing* and *Tong Ren* omit the character "Cong" (from). Hua Shi says: The outer part of the thigh is called "Bi". Below Jie Gu (GB29) is the Bi Shu. Following the posterior medial border of the outer thigh, inside the Bi Shu, between one and a half cun lateral to Cheng Fu (BL36) of this meridian, it descends and joins with that which enters the Popliteal Fossa previously mentioned.
Below, it penetrates the interior of the Spleen (Shu) (ends) to the lateral side of the little toe. Ma Yun says: "Shu" and "Shu" are synonymous. Hua Shi says: "Shu" refers to the gastrocnemius muscle. Descending, it follows He Yang (BL58), penetrates the interior of the calf, passing through Cheng Jin (BL56), Cheng Shan (BL57), Fei Yang (BL58), and Fu Yang (BL59). It emerges behind the lateral malleolus at Kun Lun (BL60), Pu Can (BL61), Shen Mai (BL62), and Jin Men (BL63). It follows Jing Gu (BL64), Shu Gu (BL65), and Tong Gu (BL66), reaching Zhi Yin (BL67) at the lateral end of the little toe, thereby connecting with the Foot Shaoyin Kidney Meridian. Yang Xuancuo says: Below the fibula is the Li Gu (standing bone). There are four ankle bones in total (two medial and two lateral). Behind each ankle bone is a Jing Gu, totaling two on each side. Zhang Jingyue says: Behind the base of the little toe, the large bone is called Jing Gu.
The thigh cannot be flexed or extended. *Jia Yi Jing* lacks the character "Bi", which seems correct. Zhang Jingyue interprets "Bi" as Bi Shu, but it is uncertain if this is accurate.
Ankle Jue (reversal cold/heat). Zhang Jingyue says: The Foot Taiyang channel emerges behind the lateral malleolus, where the sinews knot at the lateral malleolus.
This meridian governs diseases of the sinews. Zhang Jingyue says: Among all the sinew channels in the body, the Foot Taiyang is the most numerous and extensive. Its lower branches knot at the heel, the calf, the popliteal fossa, and the buttocks; its upper branches flank the waist and spine, connect with the shoulders and nape, ascend to the head to form the upper eyelid margin, and descend to knot at the calf. Therefore, any condition involving spasms, flaccidity, opisthotonos, or inability to close the eyes is due to a deficiency of Water in the Foot Taiyang meridian and falls under diseases governed by the sinews. Wang Ang says: "Governs the sinews," the meaning is unclear. Note: Taiyang diseases often present with spasms and rigidity as described above, caused by wind damaging the sinews.
Hemorrhoids, malaria, mania, and epilepsy. Zhang Jingyue says: The channel enters the anus, hence hemorrhoids; the channel belongs to the exterior, hence malaria; pathogenic factors enter the Yang, hence mania and epilepsy. Ma Yun says: *Ci Miao Pian* mentions Malaria of the Taiyang; *Dian Kuang Pian* has twenty-two sections on needling the Taiyang channel.
Neck pain. *Jia Yi Jing* adds the characters "Jian Jian" (neck area) after "Xiang".
Pathogenic factors move towards the sole of the foot. *Jia Yi Jing*, *Tong Ren*, and *Fu Hui* write "Zou" (move) as "Qu" (tend towards). Ma Yun writes it as "Qu" (hurry). Hua Shi says: Qu means to tend towards. The Foot Shaoyin begins below the little toe, slanting towards the Yong Quan (KI1) acupoint in the depression of the sole of the foot, where the toes are curled inward. Ma Yun says: Xie (pathogenic factor) is synonymous with Xie (slanting).
Emerging below Ran Gu (ends) exiting the medial aspect of the ankle. *Mai Jing* and *Qian Jin Fang* write "Gu" as "Gu" (bone). Hua Shi says: From Yong Quan, it turns out to the Ran Gu acupoint below the medial malleolus, follows down behind the Tai Xi (KI3) acupoint at the posterior medial malleolus, diverges into the Tai Zhong (KI4), Zhao Hai (KI6), and Shui Quan (KI5) acupoints within the ankle. Then, turning outside Tai Zhong, it ascends along the medial malleolus, running posterior to the Jueyin and Taiyin meridians, passing through Fu Liu (KI7) and Jiao Xin (KI8), crossing San Yin Jiao (SP6), ascending into the calf, following Zhu Bin (KI9), emerging from the medial aspect of the ankle, and reaching Yin Gu (KI10).
Danbo Yuanjie notes: The Yong Quan (KI1) acupoint of the Foot Shaoyin Kidney Meridian is in the depression of the sole of the foot, found when extending the leg, flexing the foot, and curling the toes. Ascending from Yong Quan to the anterior aspect of the medial malleolus, starting from the depression of the large bone, is the Ran Gu (KI2) acupoint. Moving five fen posterior to the medial malleolus to the depression of the artery on the calcaneus is the Tai Xi (KI3) acupoint. In the center of the heel, between the two tendons above the large bone, is the Tai Zhong (KI4) acupoint. One cun below Tai Xi and below the medial malleolus is the Shui Quan (KI5) acupoint. Four fen below the medial malleolus, anterior and posterior, between the tendon, the ankle bone above, and the cartilage below, in the depression, is the Zhao Hai (KI6) acupoint. From Zhao Hai, moving posterior to the medial malleolus, excluding about two cun above the malleolus, in the depression lateral to the bone, is the Fu Liu (KI7) acupoint. Two cun posterior to Fu Liu, along the posterior tendon, is the Jiao Xin (KI8) acupoint. Ascending obliquely laterally past San Yin Jiao (SP6) into the calf is the Zhu Bin (KI9) acupoint. Ascending further below the knee, posterior to the medial condyle, below the large tendon and above the small tendon, pressing yields a sensation, obtained by flexing the knee, is the Yin Gu (KI10) acupoint.
Ascending the posterior medial aspect of the thigh, penetrating the spine, belonging to the Kidney, and linking with the Bladder. Hua Shi says: Exiting Yin Gu, it ascends the posterior medial aspect of the thigh, penetrates the spine to meet the Chang Qiang (DU1) acupoint of the spine, returns to the anterior, follows Heng Gu (KI11), Da He (KI12), Qi Xue (KI13), Si Man (KI14), Zhong Zhu (KI15), and Huang Shu (KI16). At the location of Huang Shu, lateral to the umbilicus, it belongs to the Kidney. Descending below the umbilicus, it passes through Guan Yuan (CV4) and Zhong Ji (CV3), linking with the Bladder.
Its straight branch (ends) flanks the root of the tongue. A version in the commentary of *Jia Yi Jing* states: From Heng Gu, flanking the umbilicus, it follows up into the Lung. Hua Shi says: The straight branch ascends from the location where it belongs to the Kidney at Huang Shu, following Shang Qu (KI17), Shi Guan (KI18), Yin Du (KI19), and Tong Gu (KI20), penetrating the Liver, ascending, following You Men (KI21), crossing the Diaphragm, passing Bu Lang (ST22), entering the Lung, following Shen Feng (ST23), Ling Xu (ST24), Shen Zang (ST25), or Yu Fu (ST26), ascending along the throat, joining Ren Ying (ST9), flanking the root of the tongue, and ending. Zhang Jingyue says: Examining the Foot Shaoyin meridian in this chapter, as well as the Jing Bie and Jing Jin chapters, all state that it ascends from inside the spine to nourish the Heart and Lung, dispersing in the chest. Only *Gu Kong Lun* states: The Chong Mai originates at Qi Chuan, runs parallel with the Shaoyin meridian, flanks the umbilicus upwards to the chest where it disperses. Therefore, *Jia Yi Jing* states that Yu Fu (ST26), Shen Cang (ST25), Ling Xu (ST24), Shen Feng (ST23), and Bu Lang (ST22) are sites where the Qi of the Foot Shaoyin meridian emerges; You Men (KI21), Tong Gu (KI20), Yin Du (KI19), Shi Guan (KI18), Shang Qu (KI17), Huang Shu (KI16), Zhong Zhu (KI15), Si Man (KI14), Qi Xue (KI13), Da He (KI12), and Heng Gu (KI11) are confluences of the Chong Mai and Foot Shaoyin. Thus, Hua Shi's commentary aligns with this, actually originating from *Jia Yi Jing* and *Tong Ren*, which in turn originate from *Gu Kong Lun*.
Danbo Yuanjie notes: Ascending one cun from Heng Gu, five fen lateral to the midline, is Da He (KI12). Ascending another cun, five fen lateral to the midline, is Qi Xue (KI13). Ascending another cun, five fen lateral to the midline, is Si Man (KI14). Ascending another cun, five fen lateral to the midline, is Zhong Zhu (KI15). Ascending another cun, five fen lateral to the umbilicus, is Huang Shu (KI16). Ascending two cuns, five fen lateral to the midline, is Shang Qu (KI17). Ascending one cun, five fen lateral to the midline, is Shi Guan (KI18). Ascending one cun, five fen lateral to the midline, is Yin Du (KI19). Ascending one cun into the depression, five fen lateral to the midline, is Tong Gu (KI20). Ascending one cun into the depression, five fen lateral to the midline, is You Men (KI21). Ascending one cun into the depression, two cun lateral to the midline, taken while supine, is Bu Lang (ST22). Ascending one and six fen, two cun lateral to the midline, is Shen Feng (ST23). Ascending one and six fen, is Ling Xu (ST24). Ascending one and six fen, is Shen Zang (ST25). Ascending one and six fen, is Yu Fu (ST26). Ascending from Yu Fu to Ju Gu, below and flanking Xuan Ji of the Ren Mai, two cun lateral to the midline, in the depression, taken while supine, is Yu Fu (ST26).
Its branch (ends) pours into the Chest. Hua Shi says: The area between the two breasts is the Chest. The branch diverges from Shen Zang, circles the Heart, pours into Dan Zhong (CV17) in the chest, connecting with the Hand Jueyin Pericardium Meridian.
Illness: hunger but no desire to eat. Ma Yun says: Deficient fire being excessive causes hunger, but weakness of Spleen Qi causes lack of desire to eat. Zhang Jingyue says: Although the Kidney is a Yin organ, it houses Primordial Yang, containing Fire within Water, serving as the mother of the Spleen and Stomach. If Yin moves excessively, Yang declines; if Yang declines, the Spleen becomes troubled. Thus, although the patient feels hungry, they have no desire to eat.
Face like lacquered charcoal. *Jia Yi Jing* and *Tong Ren* describe it as face black like charcoal. *Tong Ren* commentary states: alternatively written as "Di Se" (earth color). *Su Wen* states: What is meant by face black like earth is the internal loss of Harmonious Qi, causing discoloration. (From *Mai Jie Pian*). *Fu Hui* writes "Di Se", deriving from this. Ma Yun says: Lacquer represents the black color of the Kidney manifesting externally; like lacquered charcoal indicates that the Kidney, which governs bones, is emaciated. Zhang Jingyue says: Water color is black; Yin pathogenic factors appearing on the face make it look like lacquer. The Kidney stores Essence; when Essence is depleted, the body becomes withered, hence like charcoal. Yang Xuancuo's commentary on *Nan Jing* Chapter 24 states: Lacquered charcoal refers to the seedling of Heng Shan (Actaea pauciflora). Its grass is yellow-black without luster, thus used as a metaphor. Brief note: According to Yang, lacquer refers to Shu Qi, but this cannot be verified in Materia Medica texts.
Coughing and spitting blood. Ma Yun says: The channel enters the Lung, causing cough; spitting blood indicates damage to the Kidney's governance.
Hoarse breathing and asthma. *Jia Yi Jing* commentary: alternatively written as throat wheezing. *Tong Ren* also writes throat wheezing and asthma.
Sitting but wanting to rise. Ma Yun says: Yin deficiency prevents tranquility.
Vision obscured. Ma Yun says: Water deficiency leads to weak Liver. Zhang Jingyue says: Clarity of vision resides in the pupil, which is the essence of bone. When Kidney Qi is internally depleted, the eyes appear dim as if unable to see. Therefore, anyone with frequent dark/blurred vision must have a deficiency of True Water in the Kidney.
Heart hanging like suspended, feeling like hunger. Zhang Jingyue says: When Heart and Kidney do not interact, Spirit and Essence scatter, hence the heart feels suspended. Yin deficiency causes internal heat, hence always feeling like hunger.
Prone to fear. Ma Yun says: *Yin Yang Ying Xiang Da Lun* states: The emotion associated with the Kidney is Fear. Zhang Jingyue says: Kidney Qi is timid, hence feeling fearful as if someone is about to catch them. *Jia Yi Jing* omits the fourteen characters "Qi Bu Zu...".
Jaundice and intestinal dysentery. Ma Yun says: Among the five types of jaundice, there is Female Labor Jaundice. *Tong Ping Xu Shi Lun* and *Da Qi Lun* both mention intestinal dysentery. Zhang Jingyue says: Yin deficiency and Yang excess cause jaundice. The Kidney opens into the two yin openings, hence intestinal dysentery.
Flaccidity, reversal cold, and drowsiness. *Tong Ren* commentary states: When people are exposed to toxic summer-heat, it lodges in the Kidney. Since the Kidney is a Water organ, if Water cannot overcome Fire, Bone and Marrow become deficient. Thus, the feet cannot support the body, leading to flaccidity and reversal cold. Flaccidity implies weakness, hence drowsiness. Ma Yun says: Pulse texts mention Bone Flaccidity, meaning seen in *Fei Lun*. Zhang Jingyue says: Drowsiness indicates excess Yin and deficient Yang, with depletion of Spirit and Essence. *Ni Diao Lun* states: The Kidney is a Water organ, governing fluids, bed rest, and asthma.
Moxibustion requires forcing food and generating flesh (ends) wearing heavy shoes and walking. The sixteen characters below moxibustion are moved in *Jia Yi Jing* to under "Heat and pain in the soles of the feet". Ma Yun says: For those undergoing moxibustion, one should force oneself to eat to generate flesh, loosen the belt, let hair hang loose, lean on a large staff, wear heavy shoes, and walk slowly. This avoids excessive labor due to the weakness of Kidney Qi. Other meridians do not mention this method, only the Kidney Meridian details it because the Kidney Meridian belongs to Water, the root of the body, and patients often violate its taboos, hence it is stated in detail. Zhang Jingyue says: Raw meat is rich in flavor. Rich flavors nourish Essence. Zhi says: "Sheng" should be read as "Sheng" (livestock). *Zhou Li* states: Raising initially is called "Xu"; preparing for use is called "Sheng". Ox, sheep, and pig are the Three Livestock. Sheep is a Fire animal, Ox is an Earth animal, Pig is a Water animal. Their nature is restless and prone to running. Forcing consumption of livestock meat helps Kidney Qi rise, combining with Fire and Earth. Loosening the belt allows for stretching. The essence of the Kidney is transformed by Heart Spirit into red Blood; hair is the surplus of Blood. Letting hair hang loose allows Divine Qi to descend. Large staff and heavy shoes mobilize the Qi of sinews and bones. The Qi of Yin and Yang may reverse in the arm, popliteal fossa, ankle, or bone. This chapter discusses the reversal of Shaoyin Qi in the lower body, mentioning forcing livestock meat, loosening the belt, and letting hair hang loose, because Shaoyin is the origin of Yin-Yang Vital Qi. Brief note: "Zhong" (heavy) has no explanation among previous commentators; it should be read as written.
Pericardium Luo. *Jia Yi Jing* and *Tong Ren* lack these three characters. *Fu Hui* lacks the character "Luo". Zhang Jingyue says: Xin Zhu (Heart Master) is what the Heart masters. The Heart originally belongs to Hand Shaoyin, but there is also Hand Jueyin, which is the Pericardium Luo meridian. As stated in *Xie Ke Pian*: The Heart is the great master of the five Zang and six Fu organs. All pathogens affecting the Heart affect the Pericardium Luo. The Pericardium Luo is the vessel of the Heart Master. Its entry and exit, bending and straightening, speed and slowness, are all like the Hand Shaoyin Heart Master meridian. Hence it is said: The Heart Master Hand Jueyin Pericardium Luo Meridian. *Xu Yi Shuo* Sun and *Jing Si Yi Lun* state: Some say the Pericardium Luo is the fat membrane in the chest, others say it is the flesh wrapping the Heart, both incorrect. It is the yellow fat membrane wrapping the Heart, external to the Heart, resembling fat but not fat, resembling flesh but not flesh. Externally, there are fine fascial threads connecting it to the Heart and Lungs; this is the Pericardium Luo. I believe the internal structure of animals is generally similar to humans; observing their heart shape gives a rough idea.
Danbo Yuanjie notes: Tang Rongchuan says: On the upper surface of the Heart, there is a surrounding membrane wrapping it, which is the Pericardium Luo. The Pericardium Luo connects superiorly to the Lung system, which extends to all four sides of the chest, all being oil membranes. Inferiorly, it is the net oil membrane. What is called membrane is all San Jiao. San Jiao communicates with the Pericardium Luo, as evidenced here. Thus, the Pericardium Luo meridian passes through the Diaphragm and traverses the San Jiao.
Exiting and belonging to the Pericardium Luo (ends) traversing and linking the San Jiao. Zhang Jingyue says: The Pericardium Luo is the membrane network wrapping the Heart. The Pericardium Luo is the external guard of the Heart Master, and the San Jiao is the external guard of the Zang-Fu organs, hence they are exterior-interior paired and linked. No other meridians have the character "Li" (traverse); only this one does, referring to Upper, Middle, and Lower. Upper is Dan Zhong, Middle is Zhong Wan, Lower is below the umbilicus. Therefore, the Ren Mai point Yin Jiao (CV7) is the Mu point of the San Jiao.
Its branch (ends) at the Elbow. Hua Shi says: The upper limit of the hypochondrium is the Axilla. Originating from the Pericardium, it ascends along the chest, exits the hypochondrium three cun lateral to the axilla at Tian Chi (PC1), ascends to reach the axilla, descends along the interior of the upper arm to Tian Quan (PC2), situated between the Taiyin and Shaoyin meridians, entering Qu Ze (PC3) in the elbow.
Descending the Arm (ends) emerging at its end. Hua Shi says: From the elbow, descending the arm, running between the two tendons of the arm, following Xi Men (PC4), Jian Shi (PC5), Nei Guan (PC6), and Da Ling (PC7), entering Lao Gong (PC8) in the palm, following the middle finger to emerge at Zhong Chong (PC9).
Danbo Yuanjie notes: Running between the two tendons of the arm is Qu Ze (PC3). Descending from here to the posterior palm, five cun from the wrist, is Xi Men (PC4). Descending further, three cun from the wrist, in the depression between the two tendons, is Jian Shi (PC5). Descending from here, two cun from the wrist, between the two tendons, is Nei Guan (PC6). Descending further, in the transverse crease of the wrist, between the two tendons, is Da Ling (PC7). Descending from here along the arterial pulse in the center of the palm, flexing the ring finger to locate, is Lao Gong (PC8). Descending from Lao Gong to the end of the middle finger of the hand, in the depression like the width of a leek leaf from the corner of the nail, is Zhong Chong (PC9).
Its branch (ends) emerges at its end. Hua Shi says: The fourth finger is the ring finger. Counting backwards from the little finger, it is the next finger. Called a branch because it diverges from Lao Gong (PC8) in the palm, follows the ring finger to emerge at its end, connecting with the Hand Shaoyang San Jiao Meridian.
Palpitations. *Tong Ren* writes "Dan Dan". Commentary: Xi Yanshang says: Dan Dan means water shaking. Zhang Jingyue says: "Dan" sounds like "Dan", meaning moving and unrestful.
Red face and yellow eyes. Zhang Jingyue says: The Flower (manifestation) of the Heart is the Face; the Eyes are the messengers of the Heart. Hence, disease manifests as a red face and yellow eyes.
Uncontrollable laughter. Ma Yun says: The sound associated with the Heart is laughter.
This meridian governs diseases of the Vessels. *Jia Yi Jing* commentary: Vessel, alternatively Pericardium Luo. *Tong Ren* writes Heart Vessel Luo. Wang Ang says: The Heart Master governs Blood, and the Pericardium Luo acts on behalf of the Sovereign, hence it governs the Vessels.
Originating at the end of the fourth finger (ends) ascending through the Elbow. Two fingers, *Fu Hui* writes fourth finger. Hua Shi says: The end of the arm bone is the Wrist; the end of the elbow is the Elbow. The Hand Shaoyang San Jiao Meridian originates at Guan Chong (TE1) at the end of the fourth finger, emerges between the fourth and fifth fingers, passes Ye Men (TE2) and Zhong Zhu (TE3), follows Yang Chi (TE4) at the dorsal wrist, emerges between the two bones of the forearm, follows Wai Guan (TE5), Zhi Gou (TE6), Hui Zong (TE7), San Yang Luo (TE8), and Si Du (TE9), then ascends through the elbow to reach Tian Jing (TE10). Jian note: Ascending from Guan Chong, in the depression between the metacarpals of the little and fourth fingers, grasping the fist to locate, is Ye Men (TE2). Ascending one cun from here, in the depression, is Zhong Zhu (TE3). Ascending straight from the base of the fourth finger to the depression above the dorsal wrist is Yang Chi (TE4). Ascending two cun posterior to the wrist, in the depression between the two bones, is Wai Guan (TE5). Ascending one cun from here, in the depression between the two bones, is Zhi Gou (TE6). Opening one cun laterally from here is Hui Zong (TE7). Ascending obliquely inward one cun, at the major intersection of the arm, is San Yang Luo (TE8). Ascending five cun anterior to the elbow, in the depression of the lateral aspect, is Si Du (TE9). Ascending obliquely laterally from Si Du, posterior to the tip of the lateral epicondyle of the humerus, in the gap between two tendons and bones one cun above the elbow, flexing the elbow and hugging the chest to locate, is Tian Jing (TE10).
Following the lateral aspect of the upper arm (ends) following and belonging to the San Jiao. The character "Xun" (follow) in *Jia Yi Jing* and *Tong Ren* is written as "Pian" (oblique). Zhang Jingyue says: Ascending to Tian Jing (TE10) through the elbow, it follows the lateral aspect of the upper arm, anterior to the Hand Taiyang and posterior to the Hand Yangming, passing Qing Leng Yuan (SI11), Xiao Shuo (SI12), and Nao Hui (SI13). Ascending to Jian Yu, crossing the Shoulder Well (GB21) of the Foot Shaoyang, intersecting at Tian Liao (TE15), emerging posterior to the Foot Shaoyang. The internal branch enters Que Pen, re-emerges lateral to the Foot Yangming, descends to distribute in Dan Zhong, scatters and links with the Pericardium, forming an exterior-interior relationship. Then, descending from the Upper Jiao through the Diaphragm, it follows the Middle Jiao downwards, joining the main branch of the Foot Taiyang, entering and linking with the Bladder, to regulate the Lower Jiao. Therefore, Wei Yang (BL39) of the Foot Taiyang meridian is the lower auxiliary Shu point of the San Jiao.
Its branch (ends) to the Ear. Zhang Jingyue says: The branch running externally ascends from Dan Zhong, exits Que Pen, follows Tian Liao (TE15), ascends to the neck, meets Da Zhui (DU14) and Tian You (SI16) of the Du Mai, connects with Yi Feng (TE17) and Lu Xi (TE19) behind the ear, emerges at Jiao Sun (TE18) at the upper angle of the ear, passes Xuan Li (GB2) and Han Yan (GB16) of the Foot Shaoyang, descends along the cheek to the infraorbital region, meeting the cheek portion of the Hand Taiyang.
