赋文说:如果能深入探究浮、沉、迟、数、虚、实、大、缓这八种脉象的深奥原理,就能知晓表、里、寒、热、盛、衰、邪、正这八个辨病关键的概念。
(所谓“表”,是指病位不在体内;所谓“里”,是指病位不在体表。“盛”,是指原本气血充沛不衰败;“衰”,是指原本气血不充足。“寒”,是指脏腑积聚寒冷;“热”,是指脏腑积聚热邪。“邪”,是指非脏腑本身的正常病变;“正”,是指非外邪侵袭所致。)
这八种脉象是各种脉象的纲领,这八个概念是衡量众多疾病的权衡标准。(即通过度量各种疾病,来阐明这八个关键概念。)
“虚”脉代表气血不充实,轻取重按都感觉无力。如果同时兼有弱脉和涩脉的特征。(“举”,是用轻手在皮肤表面取脉;“按”,是用重手在肌肉内部取脉。“无力”,是指手指下轻取重按时感应到的力量微弱。“弱”,是指脉象痿软而不起伏,主气虚;“涩”,是指脉象往来干涩不畅,主血少。虚脉兼有这两种特征。)
“实”脉代表气血不虚,轻取重按都有力,并且具备长脉和滑脉的形态。(“长”,是指脉动超过本位,主气有余;“滑”,是指脉流流利而不滞涩,主血有余。实脉兼有这两种特征。这是通过虚实两种脉象,来探察气血盛衰的情况。)
“迟”脉主寒,“数”脉主热,记录的是脉搏至数的多少。(正常人的脉象以每呼吸四次为基准。少于这个次数叫“迟”,即一息三至;多于这个次数叫“数”,即一息六至。经书说:数则为热,迟则为寒。这是通过迟、数两种脉象,来辨别寒热性质。)
“浮”脉主表,“沉”脉主里,取决于指下的轻重按压。(轻手在皮肤表面即可触及的叫“浮”,重按反而消失,像水浮泛一样;重手按至筋骨才能触及的叫“沉”。经书说:浮为在表,沉为在里。这是通过浮、沉两种脉象,来辨别表里病位。)
“缓”脉表示正气恢复,柔和得像春风中柳枝起舞;“大”脉表示病情进展,气势如同秋水潮生。(缓脉表示胃气恢复,如春柳般柔和,所以邪气退去而正气恢复;病情进展则危险,所以脉象洪大,如秋涛汹涌。这是通过缓、大两种脉象,来验证邪正双方的态势。)
如果六部脉象同等均匀,值得高兴,可以不用服药。(“六脉”是指双手六部的脉象。“同等”是指脉息调匀,不治自愈。王肯堂将其误解为大小、浮沉、迟数同等,这种解释不可取。)
如果六部脉象偏盛,则令人担忧,犹如薪柴将尽。(“偏盛”是指六部中哪一部单独异常。还要在该部之中,推究其呈现出八脉中的哪一种特征。王肯堂旧有的解释也是错误的。)
(Revised by Chen Xiuyuan)
The fu (rhapsody) states: If one can thoroughly explore the profound principles of the eight pulse types—floating, sinking, slow, rapid, deficient, excess, large, and moderate—one will understand the names of the eight essential diagnostic criteria: exterior, interior, cold, heat, abundance, deficiency, pathogenic factor, and healthy qi.
(The "exterior" refers to disease not located inside; the "interior" refers to disease not located outside. "Abundance" refers to originally robust and un-depleted qi and blood; "deficiency" refers to originally insufficient qi and blood. "Cold" refers to accumulated cold in the zang-fu organs; "heat" refers to accumulated heat in the zang-fu organs. "Pathogenic factor" refers to conditions that are not normal diseases of the zang-fu organs; "healthy qi" refers to conditions not caused by invasion of external pathogens.)
These eight pulse types serve as the general guidelines for all pulses, and these eight criteria act as the standards for weighing various diseases. (This involves measuring various diseases to elucidate these eight essentials.)
"Deficient" indicates that qi and blood are not substantial, feeling powerless upon both light palpation and heavy pressure. If it also presents with characteristics of the weak and choppy pulses. ("Lifting" refers to taking the pulse with light hand pressure on the skin surface; "pressing" refers to taking the pulse with heavy hand pressure within the muscles. "Powerless" means the response under light lifting and heavy pressing is weak. "Weak" refers to a pulse that is flaccid and does not rise, indicating qi deficiency; "Choppy" refers to a pulse that moves dryly and unevenly, indicating blood deficiency. The deficient pulse combines these two characteristics.)
"Excess" indicates that qi and blood are not deficient, feeling powerful upon both light palpation and heavy pressure, and exhibiting the forms of the long and slippery pulses. ("Long" refers to a pulse extending beyond its original position, indicating excess qi; "Slippery" refers to a pulse that flows smoothly without stagnation, indicating excess blood. The excess pulse combines these two characteristics. This uses the deficient and excess pulses to probe the state of qi and blood abundance or deficiency.)
"Slow" indicates cold, and "Rapid" indicates heat, recording the number of beats per respiration. (A normal pulse is standardized at four beats per respiration. Fewer than this is called "slow," i.e., three beats per respiration; more than this is called "rapid," i.e., six beats per respiration. The classics state: Rapid indicates heat, slow indicates cold. This uses the slow and rapid pulses to distinguish between cold and heat.)
"Floating" indicates the exterior, and "Sinking" indicates the interior, depending on the lightness or heaviness of finger pressure. (Touching the pulse easily with light hand pressure on the skin surface is called "floating," which disappears with heavy pressure, resembling floating water; touching the pulse only with heavy pressure down to the bones and sinews is called "sinking." The classics state: Floating indicates the exterior, sinking indicates the interior. This uses the floating and sinking pulses to distinguish between exterior and interior locations.)
"Moderate" indicates the recovery of healthy qi, gentle like willow branches dancing in the spring breeze; "Large" indicates the progression of disease, vigorous like autumn tides rising. (Moderate pulse indicates the restoration of stomach qi, harmonious like spring willows, thus evil retreats and healthy qi recovers; disease progression implies danger, hence the pulse is洪大 [large/vigorous], surging like autumn waves. This uses the moderate and large pulses to verify the balance between pathogenic factors and healthy qi.)
If the six pulses (in all positions of both hands) are equal and uniform, one may rejoice that medication is unnecessary. (The "six pulses" refer to the pulses in the six positions of both hands. "Equal" means the pulse rhythm is balanced, healing spontaneously without treatment. Wang Kentang misunderstood this as equality among size, floating/sinking, and slow/rapid, which is incorrect.)
If the six pulses show partial excess, one should worry, as if firewood is running out. ("Partial excess" means one specific position among the six is distinctly different. Furthermore, within that position, one must deduce which of the eight pulse characteristics is manifested. Wang Kentang's old interpretation is also erroneous.)
