It is not true that mugwort can induce lung cancer, but if you smell the smoke produced by burning mugwort for a long time, it may lead to an increase in the incidence of lung cancer. Wormwood is a kind of plant, which is also a kind of traditional Chinese medicine, it has the functions of dispersing cold, warming menstruation and anti-inflammation, etc. Wormwood itself is not carcinogenic, so it will not induce the formation of lung cancer in general, therefore, there is no scientific basis for the claim that wormwood induces lung cancer. As a kind of traditional Chinese medicine, mugwort can be processed into moxa floss, which can be burned to treat some clinical diseases or be used for environmental disinfection, etc. The smoke produced by the burning of moxa floss contains some carcinogenic substances, which may lead to an increase in the incidence of lung cancer in case of prolonged exposure to the human body.
