There is no evidence and clinical trials to show that moxa smoke is effective against coronavirus, but moxa smoke is also used as an ancient sterilization method for disinfection, and it can be applied appropriately in general. In addition to moxa smoke, there are many ways to be effective against coronavirus, such as applying ultraviolet disinfection for disinfection, as well as proper window ventilation at home, and disinfection by spraying with disinfectant solutions, such as using 75% medical alcohol and chlorine containing disinfectant solutions, such as 84 disinfectant solution, and also applying ether for disinfection. Coronavirus is heat sensitive and can be killed in an environment above 56°C for 30 minutes.
