What is mosquito repellent and aromatherapy?

Mosquito-repellent incense is a kind of mosquito repellent. The smoke from the medicine can drive away mosquitoes or kill them. The history of lighting mosquito-repellent incense is very long. Traditional mosquito-repellent incense is divided into thread incense and coil incense.

The smoke of mosquito-repellent incense contains four kinds of substances harmful to human body, namely, ultrafine particles-smoke (particles with a diameter less than 2.5 microns), polycyclic aromatic hydrocarbons (PAHs), carbonyl compounds (such as formaldehyde and acetaldehyde) and benzene. At the same time, in addition to these four obvious harmful substances, there are a lot of additives such as organic fillers, adhesives and dyes in mosquito-repellent incense, so that mosquito-repellent incense can be smoldered without flame.
