Wow, this is good information. I have the Clark book and was planning to build my own zapper, but wanted to do a bunch of P&B shakes first, trying to get the mucoid plaque out (and Liver Cleanses to get all the Gallstones out) since she says that it cannot reach parasites in stones or hiding under mucoid plaque. Since they seem to reproduce so fast, I thought it best to do the parasite herbs RX first, killed a big one! Then the P&B shakes, then the zapper. I do have a horrid candida problem hitting fairly often since doing the herbs.
