I have a zapper that doesnt have a red/green wire. I see plus and minus. Which one is harmful to parasites. I have 2 zappers, one is with copper handle rods, wrist bands and a 3rd one that I only use which is the silver pulser. I 've been using it for over 2 years on any body part that hurts or seems inflamed/infected etc and it seems to produce good results.
Any thoughts on the plus minus plugs? also how is the silver pulser different than the zapper.
Also where do i find that book. cant seem to find it.
