Made from the hulls and leaves of the abundant walnut tree, Black Walnut Extract has been used in culinary applications as well as natural-medicine applications for the past few centuries. Black walnuts are smaller, harder, and more pungent than the English walnuts sold in grocery stores.

As a skin wash, black walnut hulls are used to treat ringworm and yeast infections of the skin.
