Zapper effective against Candida?

Does anyone know if the Zapper works against Candida? I actually own one that I haven't used. I ordered it online for use with Parasites, but I've never really used it. My husband is thoroughly convinced the thing is a rip-off, and he kind of has me convinced. I thought about going ahead and using it anyway, but if for some reason it does work, I'm wondering if it will kill the good bacteria, too. Tweet
