两手尺中，乃神门脉也。王叔和云∶“神门诀断，两在关
后；人无二脉，病死不救。”详考其论肾之虚实，俱于尺中神门
以后验之。盖水为天一之元，万物赖以资始者也。故神门脉
绝，先天之根本既绝，决无回生之日也。而《脉诀》谓为心脉者
误矣。彼因心经有穴名神门，正在掌后兑骨之端，故错认耳。殊不知心在上焦，岂有候于尺中之理乎！
脉不行于寸口，由列缺络入臂后，手阳明大肠经也。以其不正行于关上，故曰反关。必
反其手而诊之，乃可见也。

冲阳者，胃脉也。（一曰趺阳，在足面大指间五寸，骨间动脉是也。）凡病势危笃，当诊冲阳
以验其胃气之有无。盖土为万物之母，资生之本也。故经曰∶“冲阳绝，死不治。”
太溪者，肾脉也。（在足内踝后跟骨上陷中动脉是也。）凡病势危笃，当候太溪以
验其肾气之有无。盖水为天一之元，资始之本也。故经曰∶“太溪绝，死不治。”
太冲者，肝脉也。（在足大指本节后二寸。）经曰∶“诊病患太冲脉有无，可
以决死生。”（《难经》曰∶“上部有脉，下部无脉，其人当吐；不吐者死。”）

朱丹溪曰∶“昔者轩辕使伶伦截 谷之竹，作黄钟律管，以
候天地之节气。使岐伯取气口，作脉法，以候人之动气。故黄
钟之数九分，气口之数亦九分，律管具而寸之数始形。故脉之
动也，阳得九分，阴得一寸，吻合于黄钟。天不足西北，阳南而
阴北，故男子寸盛而尺弱，肖乎天也。地不满于东南，阳北而
阴南，故女子尺盛而寸弱，肖乎地也。黄钟者，气之先兆，故能
测天地之节候。气口者，脉之要会，故能知人命之死生。世之俗工，诵高阳生之伪诀，欲以治疾，其
不杀人也几希。”（参黄子曰∶“男子阳为主，两寸常旺于尺；女于阴为主，两尺
常旺于寸，乃其常也。反之者病。”）按褚澄《尊生经》，男脉一如叔和。
女则左手寸命门、三焦，关脾、胃，尺肺、大肠；右手寸肾、膀胱，
关肝、胆，尺心、小肠。男尺常弱，初生微渺之气也。女尺常强，太阳心火之位也。遍考诸家，褚论为精。男
女阴阳之分，妊则男抱母，女背母；溺则男面覆，女面仰。男命系肾，衰自下始，故小腹先垂；女命系乳，衰
自上始，故乳房先槁。而男女尺寸盛弱，肖乎天地，越人以为男生于寅，女生于申，三阴从地
长，三阳从天生，谬之甚也。独丹溪惟本律法，混合天人而辟之，使千载之下，一旦昭然，岂不韪哉！《
脉经》曰∶“左大顺男，右大顺女。”
两手尺部，是神门脉。王叔和说：“神门脉诀断绝，在关后两侧；人如果没有这两条脉，病重时无法救治。”详细考察其论述肾的虚实，都在尺中神门以后来验证。因为水是天一之元，万物依靠它开始生长。所以神门脉断绝，先天根本既已断绝，绝对没有起死回生的日子了。而《脉诀》称其为心脉是错误的。那人因为心经有穴位名叫神门，正好在掌后高骨（兑骨）的末端，所以错认了。殊不知心在上焦，哪有通过尺部来诊察心的道理呢！
脉不经过寸口，由列缺穴络入臂后，进入手阳明大肠经。因为它不正行于关上，所以叫反关脉。必须把手翻转过来诊察，才能看到。

冲阳穴，是胃脉。（一说趺阳穴，在足面大拇指间五寸处，骨间的动脉就是。）凡是病情危重，应当诊察冲阳穴来验证胃气是否存在。因为土是万物的母亲，是资生之本。所以医经说：“冲阳脉断绝，死的无法医治。”
太溪穴，是肾脉。（在足内踝后方跟骨上方的凹陷中的动脉就是。）凡是病情危重，应当候诊太溪穴来验证肾气是否存在。因为水是天一之元，是资始之本。所以医经说：“太溪脉断绝，死的无法医治。”
太冲穴，是肝脉。（在足大脚趾本节后方二寸处。）医经说：“诊察病患太冲脉有无，可以决定生死。”（《难经》说：“上部有脉，下部无脉，这个人应当呕吐；如果不吐，就会死亡。”）

朱丹溪说：“从前轩辕黄帝让伶伦截取嶰谷的竹子，制作黄钟律管，用来测候天地的节气。让岐伯取气口，制定脉法，用来测候人的动气。所以黄钟的长度是九分，气口的长度也是九分，律管具备而寸的长度才形成。所以脉的跳动，阳得九分，阴得一寸，与黄钟相吻合。天不足西北，阳气在南而阴气在北，所以男子寸脉盛而尺脉弱，象征天。地不满东南，阳气在北而阴气在南，所以女子尺脉盛而寸脉弱，象征地。黄钟是气的先兆，所以能测候天地的节令。气口是脉的要会，所以能知道人命的死生。世间的庸俗医生，诵读高阳生伪造的脉诀，想要用它治病，不杀人的情况太少了。”（参黄子说：“男子以阳为主，两寸常旺于尺；女子以阴为主，两尺常旺于寸，这是常态。反之则是病。”）按照褚澄《尊生经》，男脉一如王叔和所述。女则左手寸部对应命门、三焦，关部对应脾、胃，尺部对应肺、大肠；右手寸部对应肾、膀胱，关部对应肝、胆，尺部对应心、小肠。男子尺脉常弱，是初生微渺之气。女子尺脉常强，是太阳心火之位。遍考各家，褚澄的理论最为精当。男女阴阳之分，怀孕时男胎抱母，女胎背母；排尿时男面向下覆，女面向上仰。男子的生命系于肾，衰老从下面开始，所以小腹先下垂；女子的生命系于乳，衰老从上面开始，所以乳房先干枯。而男女尺寸脉的盛弱，象征天地，越人（扁鹊）认为男生于寅月，女生于申月，三阴从地长，三阳从天生，错误得很。只有朱丹溪依据律法，混合天人道理来驳斥这种观点，使千年之后，一下子变得清晰明白，难道不是正确的吗！《脉经》说：“左脉大顺男，右脉大顺女。”
The *Shenmen* pulse (Spirit Gate Pulse) at the *Chi* position (Cubit position, distal part of the radial artery) of both hands. Wang Shuhe said: "If the *Shenmen* pulse is severed, located on both sides behind the *Guan* position (Middle position), and a person lacks these two pulses, when critically ill, they cannot be saved." A detailed examination of his discussion on the deficiency and excess of the Kidney shows that it is verified after the *Shenmen* point in the *Chi* position. Water is the primal origin of Heaven One, upon which all things rely for their beginning. Therefore, if the *Shenmen* pulse ceases, the root of congenital essence is severed, and there is absolutely no day for revival. The *Mai Jue* (Pulse Classic) erroneously identifies it as the Heart pulse. This mistake arose because there is an acupoint named *Shenmen* in the Heart meridian, located precisely at the end of the styloid process of the ulna (Dui bone). They confused it. Little do they know that the Heart is in the Upper Jiao; how could it be palpated at the *Chi* position?
The pulse does not pass through the *Cunkou* (Inch Port, proximal part of the radial artery) but enters the posterior arm via the *Lieque* acupoint, connecting to the Hand-Yangming Large Intestine Meridian. Because it does not run normally over the *Guan* position, it is called *Fanguan* (Reverse Gate) pulse. The hand must be turned over to palpate it to see it.

*Chongyang* acupoint is the Stomach pulse. (Also known as *Duyang*, located five cun between the big toe on the dorsum of the foot, where the arterial pulse is felt between the bones.) Whenever the disease condition is critical, one should palpate *Chongyang* to verify the presence or absence of Stomach Qi. Earth is the mother of all things, the foundation of nourishment. Thus, the Classics state: "If the *Chongyang* pulse ceases, death is incurable."
*Taixi* acupoint is the Kidney pulse. (Located in the depression above the heel bone behind the medial malleolus, where the arterial pulse is felt.) Whenever the disease condition is critical, one should monitor *Taixi* to verify the presence or absence of Kidney Qi. Water is the primal origin of Heaven One, the foundation of initiation. Thus, the Classics state: "If the *Taixi* pulse ceases, death is incurable."
*Taichong* acupoint is the Liver pulse. (Located two cun posterior to the metatarsophalangeal joint of the big toe.) The Classics state: "Palpating whether the patient's *Taichong* pulse exists can determine life or death." (The *Nan Jing* states: "If there is pulse in the upper part but none in the lower part, the person should vomit; if they do not vomit, they will die.")

Zhu Danxi said: "In ancient times, Xuanyuan Huangdi ordered Ling Lun to cut bamboo from Xie Valley to make the *Huangzhong* pitch pipe, to observe the solar terms of heaven and earth. He ordered Qibo to take the *Qikou* (Radial Pulse) to establish pulse diagnosis, to observe the vital qi of humans. Therefore, the length of *Huangzhong* is nine fen, and the length of *Qikou* is also nine fen; with the pitch pipe established, the measurement of Cun begins. Thus, the movement of the pulse: Yang obtains nine fen, Yin obtains one Cun, matching *Huangzhong*. Heaven is deficient in the northwest, with Yang in the south and Yin in the north; therefore, men have strong Cun pulses and weak Chi pulses, resembling Heaven. Earth is incomplete in the southeast, with Yang in the north and Yin in the south; therefore, women have strong Chi pulses and weak Cun pulses, resembling Earth. *Huangzhong* is the omen of Qi, thus it can measure the seasons of heaven and earth. *Qikou* is the convergence of pulses, thus it can know the life and death of humans. Vulgar doctors of the world recite the false formulas of Gao Yangsheng, intending to treat diseases; it is rare that they do not kill people." (Can Huangzi said: "Men are governed by Yang, so both Cun pulses are often stronger than the Chi pulses; women are governed by Yin, so both Chi pulses are often stronger than the Cun pulses; this is the norm. Reversing this indicates disease.") According to Chu Cheng's *Zunsheng Jing*, male pulses are exactly as described by Shuhe. For females, the left Cun corresponds to Mingmen and Sanjiao, Guan to Spleen and Stomach, Chi to Lung and Large Intestine; the right Cun corresponds to Kidney and Bladder, Guan to Liver and Gallbladder, Chi to Heart and Small Intestine. Men's Chi pulses are often weak, representing the faint initial Qi. Women's Chi pulses are often strong, representing the position of Taiyang Heart Fire. Reviewing various schools, Chu's theory is the most precise. Regarding the distinction of Yin and Yang between men and women: during pregnancy, male fetuses embrace the mother, female fetuses turn away from her; during urination, males face downward, females face upward. Male life is rooted in the Kidney, aging starts from below, so the lower abdomen sags first; female life is rooted in the breasts, aging starts from above, so the breasts wither first. The strength and weakness of Cun and Chi pulses in men and women resemble Heaven and Earth. Yue Ren (Bian Que) believed men are born in Yin month and women in Shen month, with Three Yin growing from Earth and Three Yang born from Heaven; this is extremely erroneous. Only Danxi based his argument on musical laws, integrating Heaven and Human principles to refute this, making it clear after a thousand years. Is this not correct? The *Mai Jing* states: "Left pulse large suits men, right pulse large suits women."
