Rife machines were invented in 1920’s by Royal Raymond Rife. They deliver low electromagnetic waves, like radio waves, through the hands or feet. The suggestion is that all medical conditions have an electromagnetic frequency, and that this machine will deliver pulses at the same frequency, to disable diseased cells.
Rife machines have not been scientifically proved to treat Lyme Disease or any other disease. These days, when new treatments are available for use by doctors, they have been rigorously tested to show they work, and they cause minimal harm. Rife machines have not been tested in this way. Reports that these machines are effective for Lyme disease are anecdotal and are not backed up by scientific studies.
