lol...Mia, my wife calls herself a Rife Wife because of all the time and $$$ I've spent experimenting with electro therapies. My workshop makes Dr. Frankensteins lab look like a branch-office of Radio Shack!
To put minds at rest, I can pretty-much vouch for the safety of electro therapy, because most consumer devices don't even APPROACH the physical wattage needed to produce harmful physiological effects. (however, if you live underneath high KW power poles, I wouldn't be so sure)
There's a boatload of misinformation out there that gets repeated OVER AND OVER, (like electroporation for example) and because it sounds good, it becomes conventional wisdom.
And although electroporation may be a true explanation or not, the fact is that Electro Therapy of MANY KINDS, absolutely WORK GREAT!
From personal experience, I HIGHLY recommend it. But it's hard to get started for some people because they don't understand electrical matters too well, and it's scary to hook oneself up to a mass of wiring or sit in front of radiating tubes and throw the switch!
