ZHANG Shixian's Development and Application of ZHANG Yuansu's Master-Guest Pulse Method
During the process of annotating WANG Shuhe's Pulse Classic,ZHANG Yuansu created the Master-Guest Pulse Method based on the"seven exterior and eight interior"regularities,which was used to study the complex interaction between the pulse characteristics produced by the body's normal physiological patterns(Master Pulse)and the pulse characteristics caused by diseases(Guest Pulse).However,in JIE Gu's Note on WANG Shuhe's Pulse Classic,ZHANG Yuansu only presented the ideas and outlines of the Master-Guest Pulse Method,and did not discuss the specific application methods in details.ZHANG Shixian,a master of pulse diagnosis in the Ming Dynasty,further refined the Master-Guest Pulse Method by integrating the theories of yin-yang and five elements from Classic of Questioning and numerology.He proposed associating pulse conditions and symptoms with yin-yang and five elements,and analyzing the relationship between the Master Pulse and Guest Pulse,as well as the relationship between pulse conditions and symptoms,through the interactions between yin-yang and five elements.This approach established a theoretical model for analyzing pulse conditions and illnesses using yin-yang and five elements relationships,which aided medical practitioners in learning and applying the Master-Guest Pulse Method.
