Leslie asks:

What is Rife treatment? The machine is also called a Rife frequency generator. Rife and his supporters say that each disease or condition has its own electromagnetic frequency. They also say that finding that frequency and producing an impulse of the same frequency will kill or disable diseased cells.

What do you think?

"What is Rife treatment?"
As far as I can tell, it is fraud.

Rife claimed to be able to see virus with an optical microscope, which is physically impossible. 
Rife machines are yet another fake cancer-cure.  Here's the man himself ...

Rife said the viruses he saw were motile, but viruses are not capable of moving by themselves.
( maybe he was seeing white blood cells moving across in his own retina).

I think there are some huge viruses that can easily be seen with a light microscope but that is beside the point this is obviously yet another fraurd.
