Ashi point is one of the three major categories of acupoint in acupuncture-moxibustion theory nowadays. It is originally recorded in Beiji Qianjin Yaofang（Important Formulas Worth a Thousand Gold Pieces for Emergency） as one of the effective folk methods. The theoretic development of ashi point goes through the innovation period of contemporary and modern acupuncture-moxibustion theory

specifically in three aspects

definition

property and status. Through the analysis of historical data

it is found that the bias of ashi point theory results from the misunderstanding of connotation

the distortion of application techniques

the misinterpretation of semantics and the gradual promotion of status. All of these are generally caused by the reform of acupuncture-moxibustion theory in Japan

which covers the essence of ashi point

limits its connotation and clouds the concept of acupoint. It is necessary to re-understand the literal sense and theoretic construction of ashi point and timely update the knowledge system of acupuncture-moxibustion in association with the results of theoretical researches.
