Abstract:
Objective By observing the emission of particles and various gases under different combustion conditions during moxibustion , to further discuss the safety of moxibustion therapy . Methods Eighteen moxa sticks (1g) from the same batch were put into three types of moxibustion devices and burnt out, which was detected by laser measuring dust and gas detectors.These moxa sticks were randomly divided into natural exposure group,moxa cylindrical device group and moxa cylindrical device with filter group (n=6 in each group ).Ignition was made in the sealed glass room , and PM2.5( Particulate Matter 2.5)mass concentration ,CO,SO2 and NO2 emissions were constantly monitored , and peak values of each one were noted. Results There were statistic differences among the three groups in PM2.5, CO and SO2levels. The concentration of PM2.5and the emission of CO and SO2 in group of moxa cylindrical device with filter were the lowest in the three groups (P<0.05 ) . Moxibustion did not affect the content of NO2.The peak concentration of PM2.5 in descending order was:moxibustion cylindrical de -vice group>natural exposure group>moxibustion cylindrical device with filter group.The peak emission values of CO and SO2:natural exposure group > moxibustion cylindrical device group>moxibustion cylindrical device with filter group.Conclusion There were differences in the emission of PM 2.5 , CO and SO2 in different devices. Controlling the moxa burning conditions can reduce the emission of PM 2.5,CO and SO2.Therefore physical barrier measures should be taken to effectively reduce the concentration of PM2.5 in moxibustion sites and avoid moxa smoke.
