To be on the safe side, we caution people with life-threatening anaphylactic type allergies to nut products to avoid any of our products that contain Black Walnut. We have had our Black Walnut Single Tincture, which occurs as a component of Black Walnut Combo, tested at the lab of the University of Guelph, where it was found to be allergen-free. We also had our Black Walnut Oil, an ingredient in our Red Clover Plus Salve, tested. It was also found allergen-free.
