In the south of China, there is a small deciduous tree named "Zanthoxylum bungeanum", which is called "mosquito repellent tree". There is such a name because the smoke from the branches and leaves of this tree can drive away mosquitoes. Not only that, the oil squeezed from the seeds of this tree has a strong fragrance and is a special anti-mosquito oil.

Mosquito repellent tree is a deciduous shrub belonging to Rutaceae, and it is a new type of mosquito repellent tree. It uses the unique citronellal substance on the leaf surface to disperse into the air through high-temperature evaporation to achieve mosquito repellent effect, and is distributed in tropical and temperate regions. Mosquito repellent trees can not only extract sesame oil, but also their roots, branches, leaves and fruits can be used as medicine.
