it comes from a school of thought that all illness is caused by parasites, though of course in the case of candida this is a no brainer! there's a lot of info out there on this. it's not a conventional, or FDA approved form of treatment but some people have positive experiences using it. See the Zapper Forum on this website. check out about www.toolsforhealing.com and www.aboutroyalrife.com and look up ' Hulda Clark ' and zappers on google. from my understanding, it's basically a battery driven electical device that uses special frequencies to kill different types of parasites that are supposed to cause disease.
i plan to try it.
though there's a lot of different models of zappers and I've had a hard time working out which type to get!
