"Royal Rife discovered that specific RF frequencies, when broadcast through a plasma tube towards the body, would only affect the microbes that resonated that exact frequency. And that when that frequency hit that microbe, that it would destroy that specific microbe and have absolutely no effect on anything else.
This revolutionary breakthrough stood on the shoulders of Nikola Tesla’s use of specific frequencies. This began the process of isolating frequencies and matching them to healing."

"Through computer simulations, the team has modeled the virus’ mechanical response to vibrations across a range of ultrasound frequencies. They found that vibrations between 25 and 100 megahertz triggered the virus’ shell and spikes to collapse and start to rupture within a fraction of a millisecond. This effect was seen in simulations of the virus in air and in water."
