Sit the stone in a glass of distilled water overnight preferably in a window so as to expose it to moonlight. After 24 hours, pour the solution into a dark amber bottle to preserve it (put it in a dark place, i.e. Cabinet). Drink 1 tablespoon when needed! Or, you can drink the entire glass of water if you'd like. That's what i do. Please read "Crystal Cleansing and Clearing", "Meditating With Crystals".
