(此八脉亦以不能混列统类二十七脉中,故又附人迎气口二脉之后。八脉不拘制于十二
正经,无
表里相配,故名曰奇。凡诊,八脉所见,统两手皆然,其从寸部斜至外、斜至内者,左手之
外,即右手之内,左手之内,即右手之外,相反推之自见。)
阳维 阳维候一身之表(以左手为主,其脉从寸部斜至外者是也。右手
反看,下同。)
本脉起于诸阳之会,所以维于阳,盖人身之卫分即是阳,阳维维阳即维卫,卫主表,故
阳维受邪为病亦在表,寸为阳部,外亦为阳位,故阳维之脉,从寸斜至外,不离乎阳也。
阴维 阴维候一身之里(以左手为主,其脉从寸部斜至内者是也。右手
反看。)
本脉起于诸阴之交,所以维于阴,盖人身之营分即是阴,阴维维阴即维营,营主里,故
阴维受
邪为病亦在里,寸虽为阳部,内实为阴位,阴维之脉,从寸斜至内,是根于阳而归于阴也。
阳跷 阳跷候一身左右之阳(其脉从寸部左右弹者是也。不论左右手。)
本脉为足太阳经别脉,起跟中,循外踝上行于身之左右,所以使机关之跷捷也。阳跷在
肌肉之上,阳脉所行,通贯六腑,主持诸表,故其为病,亦表病里和。
阴跷 阴跷候一身左右之阴。(不论左右手,其脉从尺部左右弹者是也
。)
本脉为足少阴经别脉,起跟中、循内踝上行于身之左右,所以使机关之跷捷也。阴跷在
肌肉之下,阴脉所行,通贯五脏,主持诸里,故其为病,亦里病表和。
督 督候身后之阳(不论左右手,其脉三部中央俱浮,直上直下者是也
。)
本脉起肾下胞中,循背而行于身之后,为阳脉之总督,故曰阳脉之海,故其为病,往往自下
冲上而痛。
任 任候身前之阴(不论左右手,其脉丸丸,横于寸口者是也。)
本脉起肾下胞中,循腹而行于身之前,为阴脉之承任,故曰阴脉之海,故其为病,亦往
往自下冲上而痛。
冲 冲候身前之阴(不论左右手,其脉来寸口中央坚实,径至关者是也
。)
本脉起肾下胞中,夹脐而行,直冲于上,为诸脉之冲要,故曰十二经脉之海。又以其为
先天
精血之主,能上灌诸阳,下渗诸阴,以至足跗,故又曰血海,而其为病,多气逆而里急。
带 带候诸脉之约束(不论左右手,其脉来关部左右弹者是也。)
本脉起少腹之侧,季胁之下,环身一周,络腰而过,如束带状,所以总约诸脉,故名曰
带。
而冲任二脉 ,循腹胁,夹脐旁,传流于气街,属于带脉,络于督脉,冲任督三脉,同起而
异行,一源而三岐,皆络带,因诸经上下往来,遗热于带脉之间,客热郁抑,白物淫溢,男
子随溲而下,女子绵绵而下,皆湿热之过,故带脉为病,即谓之带下。
(这八条奇经脉也不能混入统类中的二十七种常脉里,所以又附在人迎、气口二脉之后。这八条脉不受十二正经的制约,没有表里相配的关系,所以称为“奇”。凡是诊察时,八脉所显现的脉象,两手都是如此:从寸部斜向外的,左手的外侧即对应右手内侧;左手的内侧即对应右手外侧,反过来推演自然就能明白。)
阳维脉 阳维脉候察全身之表证(以左手为主,其脉象是从寸部斜向外的。右手则反向观察,以下同理。)
本脉起于诸阳经交会之处,所以维系着阳气。大概人体的卫分就是阳,阳维维系阳气即是维系卫气,卫气主司体表,所以阳维受邪致病也在体表。寸口为阳位,外侧也为阳位,所以阳维的脉象从寸部斜向外侧,不离乎阳的特性。
阴维脉 阴维脉候察全身之里证(以左手为主,其脉象是从寸部斜向内的。右手则反向观察。)
本脉起于诸阴经交会之处,所以维系着阴气。大概人体的营分就是阴,阴维维系阴气即是维系营气,营气主司体内,所以阴维受邪致病也在体内。虽然寸口属阳部,但内侧实为阴位,阴维的脉象从寸部斜向内,是根源于阳而归于阴的表现。
阳跷脉 阳跷脉候察全身左右两侧的阳分(其脉象是从寸部向左右弹指有力。不论左手或右手。)
本脉是足太阳膀胱经的别脉,起于足跟中,沿外踝上行至身体左右两侧,所以使关节活动轻捷灵敏。阳跷脉在肌肉之上,属于阳脉运行的路径,贯通六腑,主持诸表的机能,所以它发病时,也是表病而里和。
阴跷脉 阴跷脉候察全身左右两侧的阴分。(不论左手或右手,其脉象是从尺部向左右弹指有力。)
本脉是足少阴肾经的别脉,起于足跟中,沿内踝上行至身体左右两侧,所以使关节活动轻捷灵敏。阴跷脉在肌肉之下,属于阴脉运行的路径,贯通五脏,主持诸里的机能,所以它发病时,也是里病而表和。
督脉 督脉候察身后之阳(不论左手或右手,其脉象在三部的中央都浮取可得,直上直下。)
本脉起于肾下胞中,沿背部而行于身体后方,为阳脉的总督,所以称为“阳脉之海”,因此它发病时,往往自下向上冲逆而痛。
任脉 任脉候察身前之阴(不论左手或右手,其脉象圆滑如珠,横亘在寸口处。)
本脉起于肾下胞中,沿腹部而行于身体前方,为阴脉的承任者,所以称为“阴脉之海”,因此它发病时,也往往自下向上冲逆而痛。
冲脉 冲脉候察身前之阴(不论左手或右手,其脉象来至寸口中央坚实,径直到达关部。)
本脉起于肾下胞中,夹脐而行,直冲向上,为各脉的冲要之处,所以称为“十二经脉之海”。又因为它是先天精血的主宰,能上灌诸阳经,下渗诸阴经,直至足背,所以又称为“血海”,而其发病时,多表现为气逆和里急。
带脉 带脉候察对各脉的约束作用(不论左手或右手,其脉象来至关部向左右弹指有力。)
本脉起于少腹侧面,季胁之下,环绕身体一周,络过腰部,像束带一样,所以总约各条经脉,因此名为“带”。
而冲脉和任脉,沿腹胁,夹脐旁,传流于气街,归属于带脉,联络于督脉。冲、任、督三脉,同一起源而不同走向,一源而三歧,都联络带脉。由于各经上下往来,将热邪遗留在带脉之间,客热郁结抑制,导致白色分泌物淫溢,男子随小便而下出,女子绵绵不断而下,这都是湿热的过错,所以带脉发病,就称之为“带下”。
(The Eight Extraordinary Vessels cannot be mixed into the twenty-seven standard pulse types, so they are appended after the Renying and Qikou pulses. These eight vessels are not restricted by the Twelve Regular Meridians and lack exterior-interior pairing, hence named "Extraordinary." In all examinations, the manifestations of these eight vessels appear in both hands: the one slanting outward from the Cun position on the left hand corresponds to the inner side of the right hand, and the inner side of the left hand corresponds to the outer side of the right hand; deducing in reverse reveals this clearly.)
Yang Wei Mai (Yang Linking Vessel) monitors the exterior of the whole body (primarily observed with the left hand; its pulse slants outward from the Cun position. Observe the right hand in reverse, as follows.)
This vessel originates at the convergence of all Yang meridians, thus linking Yang. Generally, the Wei (Defensive) aspect of the human body is Yang; Yang Wei linking Yang is equivalent to linking Wei. Since Wei governs the exterior, when Yang Wei is affected by pathogenic factors, the disease also resides in the exterior. The Cun position is a Yang area, and the outer side is also a Yang location; therefore, the Yang Wei pulse slanting outward from the Cun does not depart from Yang.
Yin Wei Mai (Yin Linking Vessel) monitors the interior of the whole body (primarily observed with the left hand; its pulse slants inward from the Cun position. Observe the right hand in reverse.)
This vessel originates at the intersection of all Yin meridians, thus linking Yin. Generally, the Ying (Nutritive) aspect of the human body is Yin; Yin Wei linking Yin is equivalent to linking Ying. Since Ying governs the interior, when Yin Wei is affected by pathogenic factors, the disease also resides in the interior. Although the Cun position belongs to Yang, the inner side is actually a Yin location. The Yin Wei pulse slanting inward from the Cun indicates rooting in Yang and returning to Yin.
Yang Qiao Mai (Yang Heel Vessel) monitors the Yang of the left and right sides of the whole body (its pulse beats rhythmically to the left and right from the Cun position. Applies to either hand.)
This vessel is a branch of the Foot-Taiyang Bladder Meridian, originating in the middle of the heel, ascending along the lateral malleolus to the left and right sides of the body, thereby enabling agile movement of joints. Yang Qiao lies above the muscles, following the path of Yang meridians, penetrating the Six Fu Organs, and governing the exterior functions. Thus, when it becomes diseased, it presents as an exterior disorder with interior harmony.
Yin Qiao Mai (Yin Heel Vessel) monitors the Yin of the left and right sides of the whole body. (Applies to either hand; its pulse beats rhythmically to the left and right from the Chi position.)
This vessel is a branch of the Foot-Shaoyin Kidney Meridian, originating in the middle of the heel, ascending along the medial malleolus to the left and right sides of the body, thereby enabling agile movement of joints. Yin Qiao lies below the muscles, following the path of Yin meridians, penetrating the Five Zang Organs, and governing the interior functions. Thus, when it becomes diseased, it presents as an interior disorder with exterior harmony.
Du Mai (Governing Vessel) monitors the Yang of the posterior body. (Applies to either hand; its pulse is floating in the center of all three positions, moving straight up and down.)
This vessel originates below the kidney in the Baozhong (uterus/bladder region), runs along the back on the posterior side of the body, and serves as the commander of all Yang meridians, hence called the "Sea of Yang Meridians." Therefore, when it becomes diseased, pain often rushes upward from below.
Ren Mai (Conception Vessel) monitors the Yin of the anterior body. (Applies to either hand; its pulse is round and rolling, transverse across the Cun Kou position.)
This vessel originates below the kidney in the Baozhong, runs along the abdomen on the anterior side of the body, and serves as the bearer of all Yin meridians, hence called the "Sea of Yin Meridians." Therefore, when it becomes diseased, pain often rushes upward from below.
Chong Mai (Penetrating Vessel) monitors the Yin of the anterior body. (Applies to either hand; its pulse arrives firm and solid at the center of the Cun Kou, extending directly to the Guan position.)
This vessel originates below the kidney in the Baozhong, runs alongside the umbilicus, and rushes straight upward. It is the crucial point for all meridians, hence called the "Sea of the Twelve Regular Meridians." Furthermore, as the master of congenital essence and blood, it can irrigate the Yang meridians above and seep into the Yin meridians below, reaching the dorsum of the foot; thus, it is also called the "Sea of Blood." When it becomes diseased, it often manifests as Qi rebellion and internal urgency.
Dai Mai (Girdle Vessel) monitors the constraint over all other meridians. (Applies to either hand; its pulse beats to the left and right at the Guan position.)
This vessel originates from the sides of the lower abdomen, below the costal margin, encircles the body once, crosses the waist, and resembles a belt. Thus, it generally constrains all meridians, hence named "Dai" (Belt).
The Chong and Ren meridians run along the abdomen and hypochondrium, beside the umbilicus, flowing into the Qijie (Gas Street), belonging to the Dai Mai, and connecting with the Du Mai. The Chong, Ren, and Du meridians share the same origin but different pathways, branching from one source into three, all connecting with the Dai Mai. Due to the continuous ascent and descent of various meridians, heat pathogens are left in the Dai Mai region. The trapped heat stagnates, causing white discharge to overflow. In men, it flows out with urine; in women, it flows continuously. All are due to Damp-Heat. Therefore, diseases of the Dai Mai are termed "Dai Xia" (Leukorrhea/Down-Flow Disorder).
