Are you sure about that?

It probably won't do anything or it could kill you. Depends on the individual. Anything that is slightly toxic could be amplified 20 times or more.

That is a pretty disturbing observation, JAB.  Do you have any further information to back it up?  I note that my suggested anti-cancer protocol has included the following paragraph for aboutfive years now:

The Beck type electrical zappers are sworn to by many and appear to have a history of eliminating cancer and illness from the body. Also, a great many successes have been reported by users of genuine Rife type machines, although they are hard to find and many inferior machines parading as Rife machines are out there. There are also the Zappers of Hulda Clark, although they are not my favorite. A CureZone member known as ParaZapper has a very good machine whom many, including myself, recommend for those who decide to use such machines.

During those five years, literally many hundreds, if not thousands, have followed that protocol to at least some extent and several of the members of the 1800 plus Yahoo Oleandersoup group have indicated that the do use zappers of one kind or another.  I have never had a single report of a bad experience from them doing so.
