阴阳辨脉的补续

Supplement to pulse differentiation in terms of yin and yang

以阴阳之法辨脉是脉诊中的基本法则之一。除已为人知的部分之外,以阴阳辨脉还包括:寸口脉三部之中,单部脉搏波划过速度"数"属阳,速度"迟"属阴;一动之中,脉的升起部分称之为"来",属阳,脉的下落部分称之为"去",属阴;脉之一起一落称为"动",属阳,两动之间的静止期称为"静",属阴;右寸口脉属阳,左寸口脉属阴。根据脉搏波滑动速度迟或数的部位判断病位,分析病机;脉搏波来去、动静判断阴阳是否偏盛;左右寸口脉判断气血、阴阳的偏盛。

One of the essential principles of pulse diagnosis is to differentiate the pulse in terms of yin and yang. Apart from what has been known, differentiation of pulse in terms of yin and yang also involves the following four aspects. First, rapid pulse wave at any of the three positions of radial pulse pertains to yang, while slow pulse wave pertains to yin. Second, in one pulse wave, the rising part known as "arrival" pertains to yang, while the falling part known as "departure" pertains to yin. Third, a pulse wave, including a rising part and a falling part, known as a "move", pertains to yang, and the quiescent period between two moves known as "stillness" pertains to yin. Fourth, radial pulse at the right hand pertains to yang, while that at the left hand pertains to yin. Rapid and slow pulse waves indicate the location of the disease. Arrival and departure, and move and stillness of pulse waves can show whether yin and yang are in balance. Radial pulse at the left and right hand can tell whether qi and blood, and yin and yang are in balance or not.
