In addition, fumigation of mugwort leaves was widely used in ancient times, and many ancient documents recorded the treatment and prevention of diseases by mugwort leaves. For example, in Zhuangzi in the Spring and Autumn Period, there was a record that "people smoked more and more", and in Ai Fu written by Kong Kun, there was also a record that "people were exhausted by the sudden illness of mugwort leaves", indicating that people at that time had used the habit of smoking mugwort leaves to treat and prevent diseases.
Extended data:
The Dictionary of Traditional Chinese Medicine records the disinfection function of moxa smoke. It is considered that the fumigation of mugwort leaves has obvious disinfection effect on tuberculosis, Staphylococcus aureus, Escherichia coli, Bacillus subtilis and Pseudomonas aeruginosa, and its effect is better than that of ultraviolet rays. Fumigation with Folium Artemisiae Argyi can form an air drug molecular film indoors, and hanging Folium Artemisiae Argyi also has disinfection effect.
Volatile substances contained in Folium Artemisiae Argyi can also form a natural disinfection air curtain in the air around the human body. Bacteria and viruses that invade the human body through the respiratory system are most likely to accumulate in sinus cavity and throat. The natural bactericidal and antiviral components in Folium Artemisiae Argyi can form a "drug film" in sinus cavity, throat and trachea to accumulate a large number of antibodies, thus achieving the effects of sterilization, antivirus and prevention of infection.
Modern research shows that moxa smoke has the function of air disinfection. Moxa smoke, traditional Chinese medicine disinfectant and ultraviolet radiation were used for indoor disinfection, and the number of bacteria per cubic meter was detected and counted. The results show that the air disinfection effects of the three methods are the same.
