A Rife machine is a device that uses frequency therapy on the body. The device was introduced by Royal Rife in the 1930s, who claimed that the machine could detect microbes by the color they emitted, and later claimed that the device could cure cancer, although there is much controversy surrounding those claims.
The Rife machine uses a variable-frequency, pulsed radio transmitter to produce mechanical resonance within the cells of the body. It is believed that when the practitioner uses a specific electromagnetic frequency, it has the ability to kill bacteria or viruses within the body without damaging any healthy cells or tissues.
