It is well known that Amur cork tree, or called phellodendron amurense in scientific name and Huang Bo in mandarin, is partly grown for the purpose as timber, which is the preferred type of wood for building houses and making high-end furniture because it comes with moderate hardness, graceful wood grain, and strong corrosion-resistance properties. Similarly, this plant, especially its bark, is also an equally remarkable Chinese herb thanks to its strong anti-inflammatory effect. As a matter of fact, it is a must-have ingredient in all kinds of traditional Chinese medicine pills. Unfortunately, in recent years the growing role of its medicinal value results in excessive illegal logging and the diminishing Amur corktree resources.
