Black walnut hull — the thick green outer layer that surrounds the nut of the Juglans nigra tree — has been valued for centuries for its powerful natural properties. When fresh, the hull is bright green; as it oxidizes, it turns dark brown or black, signaling that its active compounds are becoming more potent. Long used in traditional herbal practices, black walnut hull remains one of the most versatile natural ingredients for cleansing, digestion, skin health, and more.
