Ingredient Overview
Eucommia bark is known as Du Zhong in Chinese herbal traditions. The bark of Eucommia ulmoides supplies the raw material for this concentrated botanical ingredient.
The bark is the traditionally recognised material in Du Zhong preparations. That source gives the ingredient a clear connection with the tree rather than a generic herbal label. Dry extraction focuses on the compounds obtained from the bark and provides a different form from the cut material used in traditional preparations.
