The walnut meat is excellent for eating; but it is the fresh hulls that are peeled away, turning a dark brown, that are used for making an herbal extract or oil. Black walnut hulls may support and clear the intestinal tract, act as a digestive bitter and tend to certain skin conditions. The green hull contains bitter quinones, such as juglone, fatty acids and bioflavonoids. There is a study from researchers at Johns Hopkins Bloomberg School of Public Health that highlights black walnut and other herbs for certain health concerns.Safety considerations: Short term use only.
