The truth comes down to profits for the pharmaceutical industry and for the medical profession. Neither zappers nor most other common similar electro-therapy devices can be patented because the use of electricity and frequencies for healing has existed for over 250 years. There may still be some room for some specific frequencies or specific combinations, but even these will be hard to prove. If you can not patent a product or method, then you can not obtain the finances needed to have the necessary scientific studies done and the end result is that the product becomes suppressed. Additionally, the pharmaceutical companies are at risk of loosing their profits and funding, so naturally, they would use any means at their disposal to keep such products off of the market. In the final analysis, at least for the medical industry, it comes down to a choice of, Do we receive $10,000.00 for a treatment or $50.00 for a treatment?
