脉诊有区分阴阳的方法。什么是这种方法呢？回答说：呼气时，气与心和肺相关；吸气时，气与肾和肝相关。在呼吸之间，脾接受水谷精微的气味，其脉象位于中部。
浮脉对应肺脏。
脉象有阳盛阴虚、阴盛阳虚的情况。这是什么意思呢？回答说：沉取时脉象微弱细小，浮取时脉象坚实盛大，所以称为阳盛阴虚。浮取时脉象微弱细小，（这是）阳脉出现在寸口部，浮而坚实盛大，如果轻手按压，脉象反而更加微弱细小，所以称为阳虚。重手按压时，脉象反而更加坚实盛大，所以称为阳实。
脉象有一种阴脉一种阳脉、一种阴脉两种阳脉、一种阴脉三种阳脉；有一种阳脉一种阴脉、一种阳脉两种阴脉、一种阳脉三种阴脉。这六种脉象，（其中）浮、大、数、动、滑属于阳脉；沉、涩、弱、弦、微属于阴脉。
脉形长者属阳，短者属阴。阳脉中出现阴脉特征为逆证，阴脉中出现阳脉特征为顺证。关前部位属阳，关后部位属阴。阳脉若出现数象，则可能引起呕吐。
心归属于南方丙丁火，夏季旺盛七十二天。心的脉象来势洪大而长，如火炎升腾泛滥，形态似乎位于皮肤之中，象征南方的火位。
心脉来势微微洪大，或者洪大而长的，或者连续不断像连珠一样的形状，如同手抚摸琅玕玉石一般的，都是平脉（正常脉象）。脉来急促且手部偃曲的，说明胃气少，称为病态。脉来前曲后直的，如同拿着带钩的皮带，称为气绝，主死。又说，真心脉到来时坚硬搏指，如同抚摸薏苡子一样颗粒分明，此时面色赤黑无光泽，毛发枯折的也主死。心脉息数均匀调和，且微微洪大长大的，脏腑都没有疾病，得到了本脏的正常脉候。
肝归属于东方甲乙木，春季旺盛七十二天。脉象来势弦长，以象征木的形状端直。经书说，春脉应当合乎规圆的标准。又说，春脉……（原文此处有缺漏或排版错误，依上下文推断为描述春脉特征）。
肾归属于北方壬癸水，冬季旺盛七十二天。其脉象来势沉濡而滑。沉属阴，滑象征北方的水位。经书说……（原文此处有缺漏）。十月……月……地雷……其气……之候……（原文此处文字破碎，意指冬令闭藏之气）。
肺归属于西方庚辛金，秋季旺盛七十二天。秋脉如毛，万物萧索，草木凋落。其脉象如风吹羽毛般轻浮，以应西……（原文此处有缺漏）。气升……草……落……脉……（原文此处文字破碎）。
脾归属于中央戊己土，寄旺于四季各十八天，合起来七十二天，对应一岁三百六十天的数目。脾属土，是孤脏……故……善……如……真……（原文此处文字破碎，意指脾为后天之本，滋养四方）。
右肾，肾有两个，左边为肾，右边为命门。所以男子用它来储藏精气，女子用它来储藏月经。然而命门虽然属水，（但其功能）流入肾中。肺主气，也潮润于肾。顺行则收血化为精，运入命门，滋养骨髓，运行真阳之气，上潮至脑户。所以命门承接元阳正气，上通三焦，与子午君火交泰，这是阴阳变化的征兆，也是心包络沟通阴阳变化的道路，对应五脏六腑的根源，并非由肾脉单独主管。大概命门中含有真阳之气，常常得到阴中养阳的候象。然而它与肾同样旺盛七十二天，所以脉象大体上没有太大区别。冬季脉沉濡而滑，春季脉弦滑，夏季脉洪滑，秋季脉微滑。这称为和平的脉候，也顺应四时五行的变化，这是命门的根本所在。它变化精气，长养百骸，灌溉腑脏，无所不到，而三焦的疾病，都可以从这里看出来。
There is a method for distinguishing Yin and Yang in pulse diagnosis. What is this method? It is said: Exhalation relates to the Heart and Lungs; inhalation relates to the Kidneys and Liver. Between breaths, the Spleen receives the flavors of food and drink, and its pulse is located in the middle.
The Floating Pulse (Fu Mai) corresponds to the Lung.
Pulses can manifest as Excess Yang with Deficient Yin, or Excess Yin with Deficient Yang. What does this mean? It is said: When pressed deeply (Chen), the pulse appears weak and small; when pressed superficially (Fu), it appears solid and large. Thus, it is called Excess Yang with Deficient Yin. If the pulse is weak and small upon superficial pressing, but is described as an Yang pulse appearing at the Cun Kou (Radial Artery), which is floating, solid, and large, yet becomes even weaker and smaller with light pressure, it is called Yang Deficiency. Conversely, if it becomes even more solid and large with heavy pressure, it is called Yang Excess.
There are pulses characterized by one Yin and one Yang, one Yin and two Yangs, one Yin and three Yangs; and one Yang and one Yin, one Yang and two Yins, one Yang and three Yins. Regarding these six types of pulses: Floating, Large, Rapid, Agitated, and Slippery pulses belong to Yang; Sunken, Choppy, Weak, Wiry, and Fine pulses belong to Yin.
Long pulse forms belong to Yang; short pulse forms belong to Yin. The appearance of Yin characteristics within a Yang pulse indicates a contrary (Ni) condition; the appearance of Yang characteristics within a Yin pulse indicates a smooth (Shun) condition. The area anterior to the Guan (Bar) position belongs to Yang; the area posterior to the Guan position belongs to Yin. If a Yang pulse presents with a Rapid number, vomiting may occur.
The Cun Kou position on the left hand is where the Qi of the Heart and Small Intestine emerges.
The Heart belongs to the South, associated with Bing-Ding Fire. It prospers during the summer for seventy-two days. Its pulse comes forth large, surging, and long, resembling fire rising and spreading. Its form seems to lie within the skin, symbolizing the Fire position of the South.
A normal Heart pulse comes forth slightly surging, or large and long, or continuous like a string of pearls, or smooth like touching polished jade (Lang Yu). These are all Ping Mai (Normal Pulses). If the pulse comes forth rapid and the hand curls, indicating little Stomach Qi, it is a pathological state. If the pulse feels curved at the front and straight at the back, like handling a hooked belt, it indicates the exhaustion of Qi and signifies death. Furthermore, if the True Heart pulse arrives hard and knotted, like feeling a cluster of Coix seeds, accompanied by a dark red or black complexion lacking luster and brittle hair, it also signifies death. If the Heart pulse is regular in rhythm and slightly surging, large, and long, the Zang-Fu organs are free from disease, reflecting the proper pulse pattern of the organ.
The Guan position on the left hand is where the Qi of the Liver and Gallbladder emerges.
The Liver belongs to the East, associated with Jia-Yi Wood. It prospers during the spring for seventy-two days. The pulse comes forth wiry and long, symbolizing the upright and straight nature of wood. The Classics state that the Spring pulse should conform to the circle (Gui).
The Chi position on the left hand is where the Qi of the Kidney and Bladder emerges.
The Kidney belongs to the North, associated with Ren-Gui Water. It prospers during the winter for seventy-two days. Its pulse comes forth sunken, soft, and slippery. Sunken indicates Yin; slippery symbolizes the Water position of the North. The Classics state... [Text fragmentary regarding October/Winter qi].
The Cun Kou position on the right hand is where the Qi of the Lung and Large Intestine emerges.
The Lung belongs to the West, associated with Geng-Xin Metal. It prospers during the autumn for seventy-two days. The Autumn pulse is fine like hair, corresponding to the desolation of all things and the falling of grass and trees. The pulse floats lightly like feathers blown by the wind, corresponding to the West... [Text fragmentary].
The Guan position on the right hand is where the Qi of the Spleen and Stomach emerges.
The Spleen belongs to the Center, associated with Wu-Ji Earth. It prospers for eighteen days in each of the four seasons, totaling seventy-two days, corresponding to the 360 days of a year. The Spleen is Earth, the solitary Zang organ... [Text fragmentary regarding its nourishing function].
The Chi position on the right hand is where the Qi of the Ming Men (Gate of Life) and San Jiao (Triple Burner) emerges.
Regarding the Right Kidney: There are two kidneys; the left is the Kidney, and the right is the Ming Men. Thus, in men, it stores Essence (Jing); in women, it stores menstrual blood. Although Ming Men belongs to Water, its Qi flows into the Kidney. The Lung governs Qi and also moistens the Kidney. In harmony, blood is transformed into Essence, transported into the Ming Men to nourish the bone marrow. The True Yang Qi is circulated upward to the Brain House (Nao Hu). Therefore, the Ming Men receives the Original Yang Zheng Qi, connects upward to the San Jiao, and interacts with the Ministerial Fire of Zi-Wu, representing the signs of Yin-Yang transformation. It serves as the pathway through which the Pericardium communicates Yin-Yang changes and acts as the root of the five Zang and six Fu organs, not solely governed by the Kidney pulse. Essentially, the Ming Men contains True Yang Qi and often exhibits the state of nourishing Yang within Yin. However, since it prospers for seventy-two days like the Kidney, its pulse generally does not differ significantly. In winter, it is sunken, soft, and slippery; in spring, wiry and slippery; in summer, surging and slippery; in autumn, slightly slippery. This is considered a harmonious pulse state, aligning with the changes of the four seasons and five elements. It is the root of the Ming Men, transforming Essence and Qi, nourishing the body, irrigating the viscera, and without omission. Diseases of the San Jiao can all be observed here.
