Every living and none living thing has its own resonant frequency. Every organ of the body has its own individual resonant frequency, All bacteria, viruses, parasites and fungi also have their own frequencies.
If we can produce the same frequency as a healthy organ using a frequency generator, then we can help the organ to recuperate its normal functioning. The body heals and rebalances itself when it is connected to healthy frequencies. This is the principle of BIORESONANCE.
If we take a crystal wine glass as another example, this also has its own resonant frequency around 500 Hertz. If we can produce a sound at the same frequency and stand the glass in front of a speaker, then the glass will absorb this frequency and break. This is the phenomenon of RESONANCE
