evidence: The zapper is a device invented by Dr Clark. It electrically kills parasites, bacteria, viruses, moulds and fungi. Viruses and bacteria disappear in three minutes; tapeworms, flippers, roundworms in five and mites in seven. All that is needed is a positive offset powered by a battery with a very low voltage of 5 to 10 volts. The zapper kills parasites and bacteria wherever the current reaches them. But it does not reach the eyes, appendix, testicles, inner ear bones. The current flows along the stomach or intestinal wall, not through its contents. It does not reach gallstones or living cells. The current does not flow evenly through the body. With regular zapping, the current passes mainly through our fluids, i.e. our lymphatic and vascular system, with a small fraction reaching all the organs and tissues of our body. Blood and lymph are the most important places to zap. [...] Independence of frequency. Any frequency positively shifted kills all bacteria, viruses and parasites simultaneously under sufficient voltage (5 to 10 volts, a duration of seven minutes and a frequency of 10 Hz to 500,000 Hz). Passes mainly through the fluids of our body, the lymphatic and blood system. The Varizapper is ideal for standard zapping.
