I saw what appeared to be flukes in their early stage during my two cleanses. (looked like clearish cuke seeds with tails) and according to the Clark zapping protocol, a week of zapping should clear them up. Or at least that is what it looked like to me. I have previously zapped for up to a month at a time without ever seeing any parasites (also did parasite herbs at the same time). But I am anxious to do another flush before my mother in law lands here on Sunday.
