A zapper is a personal bio-electric device that is worn against the skin to destroy parasites and promote health. It’s powered by a 9-volt battery and operates on 15Hz (frequency). 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.

Benefits of zapping
The removal of parasites, bacteria, viruses, and fungus.
A positive electrical force that pulses up and down also energizes the white blood cells to go on an all-out attack on the enemies: parasites, toxins, bacteria, everything in spite of their five immunity blockers: benzene, PCBs, metals, dyes and asbestos. For a time the WBCs turn into Super-WBCs. That is why Dr. Clark recommends eight hours of zapping daily for the sick until they are well.

Is zapping animals OK?
Yes! Start with a short period, like 3 minutes, and then work up to longer periods. Give them water afterwards.
