Objective To study the temperature distribution of indirect moxibustion for regulating moxibustion process and promoting its efficacy. Method According to the related biological heat transfer theories, a heat transfer theoretical model of indirect moxibustion was established. Based on this model,the relationship between skin temperature and the depth of inner abnormal heat source was discussed and its expression was deduced. Results According to the deduced expression, the depth of the inner heat source could be calculated, and its value was well consistent with that of the finite element stimulation. The reasonability of the theoretical model of the indirect moxibustion was also validated by the designed physical experiment. Conclusion The temperature field of indirect moxibustion would be estimated by obtaining the information of skin temperature and the heat stimulus of moxa stick, which would help better understand the heat transfer process in indirect Moxibustion and provide a foundation for treatment planning.
