To truly get rid of parasites you need electrification along with herbals.
This was your statememt. I have no problem with anyone's decision to zap. I do feel it is misleading to say to people that to truly get rid of parasites you need to zap. Both my husband and I have achieved deworming without zapping.
I am at work and will reference the page where Clark states about not reaching certain areas of the body. As for killing good flora I did get that info from the zapping forum.
I will post another question there as well.
People have been deworming with herbals for centuries. Long before the zapper was invented.
