"All parasites and diseased tissues are positively charged. The zapper introduces negative ions through the skin and into the body's living tissue, killing the parasites by reversing their polarity and also helping to heal the diseased tissue. Healthy tissue is negatively charged.
The zapper's circuitry is built around a 555 timer integrated circuit which emits a nice, positive offset square wave of direct current from a nine-volt battery stepped down to around 4.5volts and 3.5milliamp. "Positive offset" is a wave form that has alternating current characteristics. This may be important in the long run because it won't alter the body's natural electromagnetic field polarity.

Many researches have discovered by different paths that very weak electric current eliminates parasites.
I feel confident that parasites enjoy and thrive on all the vitamins, herbs and minerals that you send in there to correct the problems that are caused by the same parasites. Why else would these remedies be "hit or miss" solutions? You're only getting leftovers. After you start using a zapper, when you eat those expensive herbs, vitamins, and minerals, I believe that you, instead of your non-paying passengers, can expect to have their benefits. Parasites can't defend their positive polarity (shortage of electrons) against the introduction of simple direct current, however, and they die very quickly in its presence. Negative ions kill parasites whether they are from electric current, ozone, or magnets.

Parasites not only die when subjected to electricity, but disintegrate and are easily eliminated or assimilated as harmless nutrients. In fact, since they got most of the benefit from all the expensive supplements that you've been eating all these years, this could be your big nutritional payoff.

Viruses and fungi inside the cells, parasites in cysts, parasites with exoskeletons (like hookworms in the peripheral tissues), etc., will take longer to kill, but clearing the blood and lymphatic fluids, major organ ducts, intestinal and stomach lining, brain and central nervous system, of parasites early on will give your immune system a tremendous, immediate boost and when the hidden parasites come out of cysts and protected areas they are in for an unpleasant surprise."
