Eucommmia bark is the gray, grooved bark of the tree Eucommia ulmoides, commonly called the hardy rubber tree or the gutta-percha tree. The Chinese name for eucommia bark is Du Zhong. This name refers to a Taoist monk who was said to be immortal, suggesting that the herb provides long life, good health, and vitality. The tree is a member of the rubber family and is native to the mountainous regions of China. It normally grows to about 50 ft (15 m) in height. Small patches of bark are harvested from trees over 10 years old in late summer and early autumn. The outer bark is peeled away and the smooth inner bark is dried. This inner bark contains a pure white, elastic latex that is thought to contain the compounds that account for eucommia bark's healing properties. Older, thicker inner bark with more latex is considered more desirable for the herbalist to use than younger, thinner bark.
Although traditionally only the bark of E. ulmoides was used for healing, research in the later half of the 1990s in Japan indicates that the leaves also have healing properties. The green leaves are shiny, narrow, and pointed. The tree's flowers are very small and are not used in healing.
