Roem.), a plant of the Meliaceae family, also known as pig toon, red toon, Chunyang tree, spring vegetable tree, toon bud tree, white toon, fragrant tree. Chinese medicine uses toon leaves, Tree-of-Heaven Bark and chinese mahogany seeds as medicinal materials; the other is Heaven Ailanthus Bark, collected in Zhongguo Yaodian (Part 1) (1995 edition) Tree-of-Heaven Bark is Heaven Ailanthus Bark, which is the dried root bark or bark of Ailanthus altissima (Mill.) Swingle. Deciduous trees. Mainly produced in Zhejiang, Hebei, Hubei and Jiangsu.

The one currently used more widely is Heaven Ailanthus Bark, which is only found in Shaanxi, Sichuan, and Hubei, Guizhou and other places use Chinese mahogany skin or both.

This article was first published in Tang Bencao. Su Jing said: "The two trees are similar in shape, the acanthus is sparse, and the chun is actually different." Su Song said: "The two trees are different. They are found in both the north and the south, and the outer stems are generally similar, but the chun wood is solid and the leaves are fragrant and edible, while the acanthus wood is sparse and smelly." Li Shi-zhen said: "Chinese oak, acanthus, and castanopsis are three kinds of trees in one tree. The thin bark of the bark of the chrysanthemum is solid and red, and the young leaves are fragrant and sweet. The thick bark of the bark of the chrysanthemum is weak and white, and its leaves are smelly... The bark and root bark of acanthus are scraped off, dried in the shade, and temporarily cut and roasted for use...but the root of acanthus is particularly good." It can be seen that the Tree-of-Heaven Bark used in ancient times refers to the root bark or dry bark of two plants, Chinese mahogany and Ailanthus altissima, and ailanthus bark is the best. At present, in the Chinese market, except for a few areas where Chinese mahogany leather is used, most of them use Heaven Ailanthus Bark as Tree-of-Heaven Bark.
