In a large bottle, combine 5 cups of vinegar, a few handfuls of salt, 10 drops of High John the Conqueror oil, 1/4 cup poppy seeds (for invisibility) , and 1/8 cup each of chili powder and thistle. Stew on low heat for 1 hour. Once the potion has cooled, wash the outside of all your doors and windows with the potion. Take your time doing this and create accompanying chants and rituals if you'd like. Reapply this potion any time you feel the need for added protection.
