Mosquito repellent herb, also known as mosquito repellent herb, belongs to transgenic evergreen herb of Pelargonium of Yak Miao family. It was first cultivated by Dutch and French biologists, who used cell fusion technology to transfer the gene that can produce citronellal from citronella to geranium. It emits citronellal as mosquito repellent under natural conditions, achieving mosquito repellent effect and having lemon fragrance, hence its name.
Mosquito repellent vanilla has beautiful plant shape and fragrant smell, and has the functions of ecological mosquito repellent, air purification, refreshing, antibacterial and disinfection. When the ambient temperature is 15 degrees, it can emit lemon fragrance normally. The higher the temperature, the stronger the fragrance, and the better the effect of spraying water mist.
Due to the continuous release of citronellal, it can repel mosquitoes, purify the air, filter the smell of smoke and so on, and has no influence on human body, so it is an ideal environmental protection product. A pot of mosquito net vanilla with a top width of 20-30 cm can effectively repel mosquitoes up to 15 square meters. There are as many kinds of mosquitoes as 100.

The reason why touching incense gives off fragrance is similar to the "shyness" principle of mimosa. When its leaves are stimulated by touch, the water in the cells will act, thus changing the expansion pressure of the leaf pillow. Different from mimosa, the fragrant leaves will not shrink under the expansion pressure, but the internal pores will expand and breathe, and a volatile substance with apple fragrance will spread into the air along the pores.
In fact, touching incense generally gives off a faint fragrance, but this fragrance is weak and not easy to be detected. When its leaves are touched, the fragrance becomes stronger (also on its hands), and people think it is fragrant when it is touched.
