The link doesn't work for me. Are you trying to say that the Barefoot Herbalist is saying that zappers are a total joke~? Not trying to be arguementative, just needing clarification. I did located the section in that 108pages on parasites
and this is a quote from there
"Electronic type zappers are ok to kill parasites
“IF” the person is cleansing their body and has corrected their diet. Otherwise each time the electronic zapper is used the parasites
die and there is nothing to eat the mucus and with in minutes eggs hatch and they have plenty of food! The proper use of herbs is better in the long run. The herbs may be slower than electronics, but the herbs may not kill the beneficial bacteria near as much as the electricity. (The use of a zapper is fine during the cleansing process if you already have one.)"
