The black walnut is a native tree of North America. Black walnuts are smaller, harder, and more pungent than the English walnuts sold in grocery stores. The hulls without the meaty kernels inside are used in herbal medicine. Black walnut trees exude a sap that discourages growth of competing plants over their roots.


Juglone, vitamin C, zinc.

Typical Preparations

Tinctures, pastes and slurries. Up to 1 teaspoon of the herb 3 times a week taken internally as a tea.


Black walnut hulls contain juglone.


Black walnut hulls are safe for occasional use of up to 2 weeks at a time, but black walnut heartwood is not. Avoid herbal remedies which contain heartwood.
