Objectives : To characterize the thermal properties of several Korean electric moxibustion apparatus and to suggest methods for improving their quality for related industry as well as the welfare of Korean. Methods : We reviewed previous literatures on traditional moxibustion to find necessary factors for electric moxibustion apparatus. We measured the thermal characteristics of electric moxibustion apparatus commercially available by using an automatic temperature acquisition system in a controlled environment. Uniformity and heat loss of the apparatus were also analysed. We followed the user's manuals of apparatus provided by manufacturers. Results : Temperature control of all apparatus could not be achieved by automatic manners. Most of them were dependent on user's discretion. Maximum temperatures obtained were barely in the therapeutic temperature of $40-45^{\circ}C$. Unnecessary heating of moxibustion parts was detected. Chemicals from moxa were not properly delivered to the human skin. Conclusions : Temperature control of all apparatus needs to be improved in terms of temperature setting, retention time and maximum temperature. Design should be altered to utilize pharmacological effects from moxa to obtain its maximum efficacy. User's manuals should be revised for its clarity.
