In recent years, a shrub called "mosquito repellent" has appeared in the flower and tree market. Each pinnate leaf has 5- 1 1 lobule, which is said to have mosquito repellent effect when rubbed with lemon fragrance, so citizens often buy them and plant them in their rooms.

It is a rutaceae shrub species, introduced from Japan. It should be called "pepper" instead of "mosquito repellent" Because "mosquito repellent" is another kind of old stork herb, the two should not be confused. The latter, also known as "fragrant Tianzhu" or "mosquito net vanilla", has a single leaf and a round shape, which is very different from pepper wood and seems to be unknown in Zhongshan.

Zanthoxylum bungeanum is a plant of Zanthoxylum in Rutaceae, which is not produced in nature in China. Its close relatives are Zanthoxylum bungeanum and Zanthoxylum nitidum, both of which are aromatic flavoring or medicinal plants, but their shapes are quite different. The closest form to it is called Sichuan-Shaanxi pepper, which is produced in North China, but Sichuan-Shaanxi pepper has obvious thorns and pepper wood has no thorns, so it can be distinguished.

In addition, some people call it "Qing Xiang Mu", which is also inappropriate. Because Liquidambar formosana is another plant of Uraciaceae, its leaves are much larger than Zanthoxylum bungeanum, so don't confuse it.
