As a long-standing herbal medicine, moxa sticks can improve air quality, repel mosquitoes and moxibustion points. However, the smoke produced by the moxa stick does not kill or inhibit the new coronavirus, and there is no scientific evidence to prove that moxa sticks can have an effect on the new coronavirus. The seventh edition of the “New Coronavirus Prevention and Control Program” issued by our country has clearly pointed out that it is recommended to use chlorine disinfectant for disinfection work, the most commonly used chlorine disinfectant is 84 disinfectant or Jianzhi Su tablets, these disinfectants have a clear role in killing various pathogenic microorganisms, including bacteria and viruses, so we should believe in science, do not believe in some rumors.
