"Rife’s machine was built based on the work of Dr. Albert Abrams whom believed every disease has its own electromagnetic frequency (EMF). It was suggested that doctors could kill and eliminate disease and cancerous cells by sending an electrical impulse identical to the cell’s unique electromagnetic frequency, a theory called radionics. In radionics, also an energy balancing technique, it is believed that all microorganisms and cancer cells (lets refer to them as bugs) in the body give off electrical impulses. Therefore, these bugs inside of tumors emit specific electromagnetic frequencies as well."

"All objects have resonant frequencies at which they naturally oscillate. Pluck a guitar string and it will vibrate at a resonant frequency."
These treatments would presumably be safer for patients than many antiviral drugs that can have terrible side-effects. Normal cells should not be affected by the virus-killing lasers or sound waves because they have resonant frequencies much lower than those of viruses, Sankey said."

"Helium enclosed in a glass bulb with angled electrodes (known as a Phanotron tube) is stimulated into a plasma state (the fourth state of matter) using an audio rate square wave which is used to amplitude modulate a radio freqency (RF) carrier of approximately 27Mhz."
"The challenge of the work is finding the right combination of frequenices, RF and audio rate, which will setup standing waves inside some part of the organism, in an attempt to 'devitalize' the organism's normal biological activities."

"FSM can increase the rate of healing by up to 5 times and do so safely and effectively.
Every function in the human body is electrically based. The electricity made inside your cells provides the power for your body. When microcurrent is applied to the body at a specific frequency (speed), it can have positive effects on the condition of tissues and organs."
