（任之为言妊也，女子得之妊养也，行腹部之中行，为人生养身之本。从胞中上注目，亦长四尺
五寸）《素问》曰∶任脉起于中极之下（中极，穴名，在脐下四寸。其下则曲骨穴也，亦会阴穴之分），以上
毛际，循腹里上关元（关元，在脐下三寸，附足厥阴肝经，为生化之原），至咽喉，上颐，循面入目（循承浆环
唇，上至龈交分行，系两目下之中央，会承泣而终。承浆、承泣，并穴名，承浆在唇下陷中，承泣在目下七分）。
属阴脉之海（滑伯仁增此句）。为病，男子内结七疝（内结腹里，若结不通也。七疝者，一厥、二盘、三寒、
四瘕、五附，六脉、七气也），女子带下瘕聚（瘕者，假物之形。其名有八，蛇瘕、脂瘕、青瘕、黄瘕、燥瘕、
血瘕、狐瘕、鳖瘕也。聚者，聚而成块无常处也。瘕聚于腹，多因停血所致）。
《灵枢》曰∶任脉之别，名曰尾翳，下鸠尾，散于腹。实则腹皮痛，虚则痒搔，取之所别也（滑伯仁曰∶
督与任一原而二歧，督则由会阴而行背，任则由会阴而行腹。夫人身之有任督，犹天地之有子午。然人身之任督，
以腹背言；天地之子午，以南北言，可以分可以合者也。分之以见阴阳之不杂，而合之以见浑沦之无间也，
一而二，二而一者也。沈承之曰∶任督二脉，上则交于龈交，下则会于会阴，此二穴者，实二脉之枢纽也，故修养家，
以五更漱咽津液，盖取二脉阴阳交会之气也）。
（“任”字的意思是妊娠，女子得到它就能孕育滋养生命，它行走在腹部正中，是人身生长发育的根本。从胞宫向上经过目部，全长四尺五寸）《素问》说：任脉起始于中极穴之下（中极，穴位名，位于脐下四寸。其下方则是曲骨穴，也是会阴穴的分布区域），向上到达阴毛边缘，沿着腹腔内部上行至关元穴（关元，位于脐下三寸，归属于足厥阴肝经，是生化之源），直至咽喉，上行至下巴，沿着面部进入眼睛（沿着承浆穴环绕嘴唇，上行至龈交穴分叉，联系两眼下方的中央，与承泣穴汇合而结束。承浆、承泣，均为穴位名，承浆位于唇下的凹陷处，承泣位于眼下七分处）。属于阴脉之海（此句由滑伯仁增补）。发生病变时，男子会出现腹内结聚成七种疝气（腹内结聚，如同结块不通。七疝是指：一厥疝、二盘疝、三寒疝、四瘕疝、五附疝、六脉疝、七气疝），女子会出现带下病和瘕聚病（瘕，指假借物象形成的肿块。其名有八种：蛇瘕、脂瘕、青瘕、黄瘕、燥瘕、血瘕、狐瘕、鳖瘕。聚，指聚集成块且位置不固定。瘕聚在腹部，多因瘀血停滞所致）。
《灵枢》说：任脉的别络，名叫尾翳，向下经过鸠尾穴，散布于腹部。实证表现为腹皮疼痛，虚证表现为瘙痒抓挠，治疗应取该别络的穴位（滑伯仁说：督脉与任脉同源而异为两支，督脉从会阴穴行于背部，任脉从会阴穴行于腹部。人身的任督二脉，就像天地的子午线一样。然而人身的任督是以腹背而言；天地的子午是以南北而言，是可以分开也可以合并的。分开来看是为了显示阴阳不混杂，合并来看是为了显示浑然一体没有间隙，是一分为二、二合为一的关系。沈承之说：任督二脉，向上交汇于龈交穴，向下会合于会阴穴，这两个穴位实际上是两条经脉的枢纽，所以养生家，在五更时分漱口吞咽津液，大概是取用这两条经脉阴阳交会之气的缘故）。
(The character "Ren" implies pregnancy; for women, it governs gestation and nourishment. It runs along the midline of the abdomen and serves as the root of human life and growth. It originates from the Baozhong (uterus/bladder area), ascends to the eyes, and is four chi and five cun in length.) The *Suwen* states: The Ren Mai (Conception Vessel) originates below the Zhongji point (Zhongji, an acupoint located 4 cun below the umbilicus. Below it lies the Qugu point, which is also part of the Huiyin point's distribution). It ascends to the pubic hair margin, follows the interior of the abdomen upward to the Guanyuan point (Guanyuan, located 3 cun below the umbilicus, affiliated with the Foot Jueyin Liver Meridian, and is the source of biological transformation), reaching the throat, ascending to the chin, following the face into the eyes (following the Chengjiang point around the lips, ascending to the Yinjiao point where it branches, connecting to the center below both eyes, and terminating at the intersection with the Chengqi point. Chengjiang and Chengqi are both acupoint names; Chengjiang is in the depression below the lower lip, and Chengqi is 7 fen below the eye). It belongs to the Sea of Yin Meridians (This sentence was added by Hua Boren). In disease, men may suffer from internal accumulation of seven types of hernia (internal accumulation in the abdomen, resembling a knot that does not resolve. The seven hernias are: one Jue, two Pan, three Han, four Xia, five Fu, six Mai, and seven Qi). Women may suffer from leukorrhea and mass accumulation (Xia refers to masses formed by pseudo-material shapes. There are eight names: Snake Xia, Fat Xia, Green Xia, Yellow Xia, Dry Xia, Blood Xia, Fox Xia, and Turtle Xia. Ju refers to masses that gather into lumps without fixed locations. Masses accumulating in the abdomen are often caused by stagnant blood).
The *Ling Shu* states: The collateral branch of the Ren Mai is named Wei Yi (Weiyi), descending from the Jiutail point and dispersing into the abdomen. In excess conditions, there is pain in the abdominal skin; in deficiency conditions, there is itching requiring scratching. Treatment should target the point of its branching (Hua Boren stated: The Du Mai (Governing Vessel) and Ren Mai share the same origin but diverge into two paths. The Du Mai travels along the back from the Huiyin point, while the Ren Mai travels along the abdomen from the Huiyin point. Just as heaven and earth have Zi and Wu (North-South), the human body has Ren and Du (Front-Back). They can be divided to show the non-mixing of Yin and Yang, and united to show the seamless wholeness. They are one becoming two, and two becoming one. Shen Chengzhi stated: The Ren and Du meridians intersect above at the Yinjiao point and converge below at the Huiyin point. These two points are the pivots of the two meridians. Therefore, practitioners of cultivation swallow saliva at dawn, taking advantage of the Qi of Yin-Yang intersection between these two meridians).
