[The "sensation-efficacy" relationship of moxibustion from the perspective of the "Three Phases of moxibustion sensation"].

The theory of the "Three Phases of moxibustion sensation", originating from ZHOU Meisheng's Moxibustion Cord, summarizes the clinical transmission process of moxibustion sensation into three phases: initial sensation, diffusion, and conduction. Inspired by this theory, the authors analyze factors affecting moxibustion sensation-including moxibustion temperature, location, dose, and technique-and summarize its guiding role in clinical practice. It is proposed that in clinical application, the generation pattern of the initial sensation phase can be used to judge the immediate efficacy of moxibustion and adjust treatment locations accordingly; the diffusion pattern of the diffusion phase can help assess individual moxibustion dose to ensure optimal therapeutic effects; and the conduction phase not only indicates the endpoint of moxibustion therapy but can also reveal hidden lesions and deeper pathological causes in patients. In addition, due to differences in patient constitution and disease state, the manifestation of moxibustion sensation may not always strictly follow the pattern of the "Three Phases", requiring careful clinical differentiation.
