Abstract Objective To understand the effects of indoor air pollutants on human health during the treatment of moxibustion in traditional Chinese medicine clinic. Methods From April to May 2018, the concentration changes of carbon menoxide (CO), supended particles (PM10, PM2.5), formaldehyde (HCHO) and volatile organic compound (TVOC) during the combustion of old and new moxibustion in the simulated clinic were monitored and analyzed quantitatively. Results There were statistically significant differences in water content and ash content between Aged Artemisia argyi and New Artmisia argyi (P ＜ 0.05). Many combustion emissions of gas pollutants under the New Artmisia argyi, but suspended micro chips emissions was higher than the New Artmisia argyi. Based on the four-parameter Sigmoid equation, the highest concentration of CO in combustion emission of Aged Artemisia argyi was only 41.1% of that of New Artmisia argyi, 21.4% of TVOC and 55.8% of HCHO. Aged Artemisia argyi combustion produced PM10 and PM2.5 were higher than New Artmisia argyi, among which, Aged Artemisia argyi PM10 peak was about 1.70 times of New Artmisia argyi PM10, Chenai PM2.5 peak was about 1.85 times of New Artmisia argyi PM2.5. Conclusion The gas pollutants produced in the process of moxibustion are lower than the national safety standards, but the burning of Aged Artemisia argyi and New Artmisia argyi both caused the instantaneous total suspended particulate in the clinic to significantly exceed the standard, resulting in a potential health impact on the human body.
