How does it work?
Dr. Rife's technology is based on the well known scientific principle that movement creates heat. He determined that applying focused vibration to cancer cells destroys the cells without harming surrounding healthy tissue. The reason is that cancer cells have unusually high iron content; applying a specific type of vibrational field to these cells heats the iron, causing the cancer cells to overheat and die. This technology also works against bacteria and viruses which also contain iron.
It is FDA approved?
The FDA won't aprove this technology for one main reason. Profits. It cuts too much into their business. This technology kills pathogens and solves the problem. The FDA want to treat, not solve.
Any proven statistic or testimony?
Yes. Many. Please check out the book by Barry Lynes, The Cancer Cure that Worked, and the book by Bryan Rosner, Lyme Disease and Rife Machines. Also search yahoo, google for " rife machine ".
