Black Walnut Hull Powder (Juglans nigra) is a finely ground preparation of the dried outer hull of the black walnut, traditionally used in Western herbalism for its cleansing, astringent, and antiparasitic properties. Known for its dark color, earthy aroma, and potent bitter flavor, this powder has been used for centuries to support intestinal health, skin clarity, and microbial balance. The hull of the black walnut is rich in naturally occurring compounds like juglone, tannins, and iodine, which contribute to its traditional role in expelling intestinal parasites, supporting digestion, and promoting detoxification. It is often included in herbal cleansing protocols aimed at reducing fungal overgrowth, worms, or other gastrointestinal imbalances, especially when combined with herbs like wormwood and clove. In topical use, black walnut hull has also been applied for its drying and antimicrobial qualities, historically used in poultices or washes for skin irritations, fungal infections, or wounds. When used internally, Black Walnut Hull Powder should be taken in small, measured doses and typically for short durations, as its potent bioactive compounds can be strong on the system. It is commonly encapsulated or added to water or tincture blends for ease of use. Each batch of Black Walnut Hull Powder (Juglans nigra) is carefully dried and milled to preserve its potency and integrity. Whether used in cleansing protocols, traditional skin support remedies, or gut health formulations, this powerful herbal powder offers a time-honored method for natural purification and microbial balance.
