Unfortunately people like Sharry E make their living SELLING these types of snake oil treatments. There IS valid science behind this type of approach but again unfortunately unscrupulous people take advantage and sell bogus equipment and such. I worked with a few folks selling ionic footbath tech, I suggested using pulsed DC currents at certain frequencies to one fellow and he stole my idea and ran with it ... not sure if he got the technique correct. Long story short he made a crap load of money from my idea and I got shoved out of the picture ... do you get the picture when it comes to this stuff ? The Chinese did the same damned thing ... they stole intellectual property and made their own versions. I just had to re-engineer one of the Chinese footbath units to work after mine failed to work at all. It's working fine now but still really can't tell if the approach they used to determine effectiveness was correct.
This type of approach using EMF is so easy to fake or whatever to make a bunch of cash selling USELESS junk !
Again don't get me wrong here ... the approach has definite merit BUT you HAVE to get it RIGHT and use equipment that usually takes many many tens of thousands of research dollars to get what you are looking for.
The Germans have some of the best equipment in this area and they usually cost in excess of $20,000 and these are the cheaper ones.
And even then, some of the German equipment is useless junk selling at unGODly amounts of cash or it's fake junk stolen by snake oil salesman ... buyer BEWARE !

The other thing that crossed my mind quite some time ago about this stuff is the placebo effect. An unsuspecting user may just BELIEVE BLINDLY enough that their own body heals itself ... hence placebo effect and the science is just bunk.
Royal Raymond Rife DID prove that you can kill either virus or bacteria or whatever using certain frequencies and this still stands. BUT no ONE has been able to replicate what he did ... at least not anyone in the public domain. No ONE has yet to replicate his incredible microscope ... again at least in the public domain.

I am quite sure the elite HAVE replicated much much much of these old discoveries and keep this tech for themselves. But anyone out there online are probably selling fakes ... junk ... my reason for this line of thinking is the selling price/cost. It's super expensive and they make a killing really fast and then disappear only to resurface down the road to sell yet another bogus tech/idea. It could even be the elites themselves enriching their accounts further by selling junk based on REAL science but guess what ? It doesn't work ...and they get richer. And of course, there are the average Joe's who catch on and try and get some gravy from that train.

Take it from someone who has followed this stuff for a very long time.
