Analysis of ZHANG Yuansu's Master-Guest Pulse Method
The Master-Guest Pulse Method is a pulse theory first put forward by ZHANG Yuansu in JIE Gu's Note on WANG Shuhe's Pulse Classic,of which the purpose is to deal with the complex situation of the interaction between the master pulse(the pulse reflecting the patient's own qi and blood circulation pattern)interacts with the guest pulse(the pulse reflecting the characteristics of external pathogenic qi).The Master-Guest Pulse Method is closely related to the seven exterior and eight interior theories in Pulse Classic.ZHANG Yuansu,summarized the regularities of normal pulse patterns and the laws of abnormal pulse patterns on the basis of the previous generation's theory of pulse diagnosis.He further proposed the concepts of the master pulse and the guest pulse,which are a pair of relative concepts.Only when exogenous pathogenic factors invade the human body will the concepts of the master pulse and the guest pulse exist.When there is no external pathogenic invasion,the master pulse that exists alone can only be called a normal pulse.The interaction between the master pulse and the guest pulse is the actual pulse pattern that the patient exhibits.This theory suggests that pulse diagnosis is no longer purely an empirical summary,and it provides a theoretical basis for explaining the causes of different pulse patterns observed in clinical practice.During the Yuan,Ming and Qing dynasties,many doctors held a critical attitude towards Pulse Classic,and the Master-Guest Pulse Method was also implicated and not widely circulated.However,its thought of dealing with complex and contradictory clinical information has high reference value for the research of traditional Chinese medicine diagnostics.
