Re: How do Bob Beck and ParaZapper work to kill microbes in blood?

I found this link: http://educate-yourself.org/lte/biphasicelectrification20oct11.shtml.

The part I am wanting to understand is this statement:
"Q: What may happen if positive or negative only dc applied?

A: There can be clutterings of molecules, macro molecules or blood impurities around the electrode application zones inside the veins. At that phase these may
seem to be harmless but when these clutters dislocate with blood stream, if they find (and believe me they will) their way to any capillary veins they end up with blocking them. The small cellular zone around the blocking is destinct to die because of lack of logistics supplied by blood. That may happen near the skin
, in the heart or brain anywhere, resembling a russian roulette."

Is this a problem with Hulda Clark type zappers, or has this been dealt with?

Also I forgot to ask which part of the body the Hulda Clark zappers work on. Do they work on parasites in the the blood like Bob Beck or do they work on other things?
