Walnut Leaf Green Black (Juglans nigra): The Green Hull Preparation

The “Walnut Leaf Green Black” designation in the Herba Naturalle herb index refers to preparations made from the green (unripe) outer hull of Black Walnut (Juglans nigra) — a preparation significantly more concentrated in juglone than the dried leaf, and used in clinical herbal practice specifically for its intensive antiparasitic and antifungal activity. This is the preparation popularised by the American herbalist Hulda Clark for parasite protocols, and it is the most potent preparation from the Black Walnut tree.

Clinical Applications

Intensive Antiparasitic Protocols

The primary application of the green hull preparation. The exceptionally high juglone content in fresh green hulls provides potent activity against intestinal parasites — classically used as part of parasite cleanse protocols alongside Clove and Wormwood (the “Hulda Clark” combination), though always under qualified clinical supervision.

Antifungal (Systemic and Topical)

The concentrated juglone content provides potent Candida and fungal inhibition — used in intensive gut dysbiosis and Candida protocols.

Skin (Topical)

Diluted green hull tincture is a highly effective topical antifungal — used for athlete’s foot, nail fungus, ringworm, and other fungal skin conditions.
