I have noticed people blogging about using voltage through aluminum to produce their own charged water-BAD BAD BAD idea, current through metal in solution produces Colloids. PURE Silver-good, Alumninum-BAD-very toxic-dont do it-EVER!.
Nine volt battery-wrong-it takes a minimum of 32 volts (DC current not AC) and enough amperage to create the correct size of colloid that can be used medically by the body without any toxicity.
OH, and the electrical solution of PURE Silver-hint hint-should be made in a glass container-never metal- away from any source of natural light and stored in dark glass, never plastic or metal.
