English NameEucommia Bark P.E. Latin Name Cortex Eucommiae Plant Description: Eucommmia bark is the gray, grooved bark of the tree Eucommia ulmoides, commonly called the hardy rubber tree or the gutta-percha tree. 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 barks healing properties. Older, thicker inner bark with more latex is considered more desirable for the herbalist to use than younger, thinner bark.
