Hm. I'm sure I read that electronic methods make acid in the body. Well, I'm not an expert either, so it could be wrong. Also, I'm just not sure that the zapping kills the parasites, what if they just move to other parts of the body? Zapping didn't really do anything for me is all, I was only answering the original question, which was why or why not do you zap. I don't have any hard evidence on this. But it mostly came from the Ask Barefoot Herbalist site. I did, however like the internal Russian zapper.
