We prepare our Black Walnut extract from the fresh, unripe green outer hull of Juglans nigra trees which are responsibly wildcrafted by hand each summer in Kentucky.
Black Walnut Extract from Herb Pharm is made from the fresh (undried) fruit hulls of Juglans nigra trees which are Sustainably Wildcrafted in their natural wild habitat.
To assure optimal extraction of Black Walnuts bioactive compounds, the fruits are hand-harvested only in 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.
