WALNUT LEAVES/SHELLS – (JUGLANDIS FOLIUM)

Walnut Leaves/Shells (Juglandis Folium) come from the walnut tree (Juglans species), most commonly the English walnut (Juglans regia) and black walnut (Juglans nigra). Both the leaves and the shells of the walnut tree have been used for centuries in traditional herbal medicine for their various health benefits.

Botanical Characteristics of Walnut Leaves/Shells

Appearance of Walnut Leaves: The leaves of the walnut tree are large, pinnately compound, meaning they consist of multiple leaflets arranged along a central stem. The leaflets are lance-shaped, serrated at the edges, and have a rich, dark green color. In the fall, the leaves turn yellow before they drop.
Appearance of Walnut Shells: The hard shells surrounding the walnut nut are brown and wrinkled when mature. The inner nut, once removed, is edible, while the outer shell has a rough texture and is used in herbal medicine. The hull or outer part of the walnut shell, which is typically green when immature, is used for medicinal purposes, though dried, mature shells are also utilized.
