hi there! I use the $10 zapper from zapperplans.com for any ailments of mine(like you've probably heard me say before :-) ). It's always good to remember that in Dr. Clarks book( The Cure For All Diseases
) she said "Any positively offset [DC] frequency kills all bacteria, viruses and parasites
simultaneously given sufficient voltage (5 to 10 volts), duration (seven minutes), and frequency (anything from 10 Hz to 500'000 Hz)." So if you need a zapper, I'd recomend mine. If you'd like a different one, there's lots of great ones out there! Some use the terminator, some parazapper, and some others out there :).
hope this helps!
