Botanical Name: Juglans nigra plant Part extracted: fresh Green Hull 2 other Ingredients: Certified Organic grain alcohol, vegetable glycerine & acetic acid (0.352%). Description: we prepare our Black Walnut Extract from the fresh (undried) fruit hulls of Juglans nigra trees which are Custom wild crafted in their natural wild habitat. 2 to assure optimal extraction of black Walnut's bioactive compounds the fruits are hand-harvested only in early autumn when their hulls are still green but are beginning to soften. The hulls are removed from the outside of the fruits and are then promptly extracted while still fresh and succulent. Our Black Walnut is never fumigated or irradiated.
