An Introduction to the Benefits and Uses of the Chinese Ash: High Medicinal, Economic and Landscaping Value

The Chinese ash (Fraxinus chinensis) is a deciduous tree of the genus Fraxinus in the family Oleaceae, named for the fact that the white wax insect can be reared on its branches and the white wax secreted by the insects can be harvested. It is cultivated in many regions across both northern and southern China. With an upright trunk and dense foliage, it is both a traditional economic tree species and a common landscaping tree.

From a medicinal perspective, the dried bark of the Chinese ash is known in traditional Chinese medicine as Qinpi (Ash Bark). It is traditionally regarded as cold in nature with a bitter and astringent taste, and is mostly used to address conditions such as damp-heat diarrhea and dysentery, and red, swollen, painful eyes. However, everyone's constitution is different, so whether it is suitable and how it should be combined with other herbs should be discussed with a professional physician; do not strip the bark yourself to use as medicine.

In terms of economic value, the insect white wax secreted by the white wax insect is fine and tough in texture, traditionally used to make candles, sealing and polishing materials, and can also serve as an excipient for pill coatings. The wood of the Chinese ash is tough and elastic, suitable for making tool handles, furniture parts and sports equipment, with quite a wide range of uses.

As a landscaping tree species, the Chinese ash tolerates pruning well and has strong adaptability, and it also has a certain tolerance to smoke and dust, so it is often used as a street tree or shade tree in courtyards. Its leaves turn yellow in autumn, giving a pleasant ornamental effect. Overall, the Chinese ash combines medicinal, industrial and ornamental value, but when it comes to medicinal use, caution is still needed, and it is advisable to use it reasonably under a doctor's guidance.
