It works but the idea isn’t new. I learned about rubbing the green walnuts on our leather boots as a cover scent back in the late 1980s and it wasn’t a new idea back then. They stink but not as bad a coon pee or fox urine.
Off topic but my father in law is from Ukraine, served in the soviet military and could probably kill me pretty easy. He had to help build apartments to help evacuate irradiated areas around Chernobyl, but it turns out the apartments were too close so it was all that exposure to who knows what wasted for nothing. Two weeks ago a tooth was bothering him so he pulled it out with a string and sloshed vodka around in his mouth to complete the surgery.Probably adapted from Black Walnut Tincture...which uses Vodka...and was notably used at the Chernobyl fallout ...so a slight modification of a concept that's surely even older. Swap in water, drink the Vodka, lol.
Don't Compost Those Black Walnut Hulls! Make a Black Walnut Tincture Instead
Make black walnut tincture with the green hulls from black walnuts for its antifungal properties or as an external iodine supplement.joybileefarm.com
