Black Walnut is rich in organic iodine and tannins which provide antiseptic qualities. As an infusion it is good for all toxic blood conditions. The tincture can be used to paint sores and pimples. It may be used for bleeding surfaces or moist skin diseases (apply tincture or powdered leaves). Use the infusion as an injection for vaginitis, bleeding, piles, intestinal worms, dysentery, prolapsed intestines and prolapsed uterus. It is good as a fomentation for ringworm and scabies.
