Mugwort has no effect on the new coronary virus. Mugwort, as a traditional Chinese medicine herb used for a long time, can improve air quality, repel mosquitoes and avoid filth, as well as warm acupuncture points. However, the smoke produced by moxa does not kill or inhibit the novel coronavirus, and there is no scientific evidence to confirm that moxa can have an effect on the novel coronavirus. The seventh edition of the New Coronavirus Prevention and Control Program issued by our country has clearly pointed out that chlorine disinfectant is recommended for disinfection, and the most commonly used chlorine disinfectant is 84 disinfectant or Jianzhisu tablets, which have the effect of killing various pathogenic microorganisms, including bacteria and viruses, so we should believe in science, and don’t believe in some rumors.
