Objective : The purpose of this study is to investigate the mechanism and effect of moxibustion objectively and to be used as the quantitative data for developing the new thermal stimulating treatment by observing the combustion time and temperature of commercial moxaes.
Methods : We have selected two types(large-size moxa A(LMA), large-size moxa B (LMB)) among large moxaes used widely in the clinic. We examined combustion times, temperatures in each period during a combustion of moxa.
Results : 1. The combustion time in the preheating period was about 30sec in both moxaes on the non-contact heated surface.
2. The combustion time in the heating period was about 345sec in LMA and about 1391 sec in LMB, about 4 times longer in LMB on the non-contact surface.
3. The maximum temperature in the heating period was 44.5℃ in LMA and 45.4℃ in LMB respectively, higher by 0.9℃ in LMB. The average temperature in the heating period was 35.5∼37.6℃ in LMA and 36.0∼39.8℃ in LMB, a little higher in LMB.
4. The combustion time in the retaining period in LMA was 45.4sec and 13% of that in the heating period, and in LMB 594.7sec and 43% of that in the heating period on the non-contact surface.
5. On the point(PH) measured maximum temperature, the average temperature during the retaining period was 44.0℃, 42.9℃ respectively and the temperature at an end of the retaining period was 43. 0℃, 40.2℃ respectively.
6. The time at a beginning of the cooling period was about 418 sec from ignition in LMA and 2021sec in LMB, and the temperature at that time was 36.9-39.1℃ on the non-contact surface.
Conclusion : It was thought that not only the figure of moxicombustion device, but also the form and size of moxa had influence on the combustion characteristics deciding the performance of stimulus seriously.
