《黄帝内经》脉法——动者为阳,静者为阴的解析

Resolving the sentence: Action pertains to yang, silence pertains to yin, a pulse diagnosis principle in Inner Canon of Huangdi

按照阴阳分类法分析脉象,为《黄帝内经》脉法的要点之一,对《素问·阴阳别论篇》所述"静者为阴,动者为阳",历代医家均未能予以明确解释,以致无法理解其含义并应用这一原理。笔者根据《黄帝内经》中脉象的记载及临床实践,发现"动"即是指一个脉搏的起落,并不是指脉"数";再通过排除法分析,"静"即是指两个脉搏之间的静止期。《素问》所述的含义是:脉的一个搏动期(一个起落)为"阳",两个搏动之间的静止期为"阴"。其目的是通过比较"静"、"动"的时间长短,以判断阴阳的盛衰。

Analyzing the pulse manifestation with classification of yin-yang is one of key points in Inner Canon of Huangdi. One saying in Suwen is that silence pertains to yin, action pertains to yang. From past dynasties to now, it has not been explained clearly, and could not be used in clinic. According to the records about pulse diagnosis in Inner Canon of Huangdi and my clinical practice, it is not difficult to find that the up and down of a pulse is called action, the interval between two actions is called silence. The aim is to determine the waxing and waning of yin-yang of the body by comparing the lengths of action and silence.
