There's a rife forum on cure zone if you want to read up on it. You could probably find a practicioner to do Rife sessions if you don't want to buy one. It's hard to find them used as people don't want to give them up once they get them, so that tells you something, IMHO.
Have you looked into cleansing? If it were me, I would start doing cleanses and this is how I'd do it:
Kidney Cleanse drink (Andreas Moritz kidney tea, get online)
Colon cleanse (colonics asap! enemas and or/ Mag07 or OxyPowder)
Liver Flush (per Andreas Moritz book, and I wouldn't stop until I had 3 consecutive flushes with no stones, this could take anywhere from one year to two years, health massively improves and clogged liver is ultimate reason for bugs in the colon/body)
Heavy Metal Cleanse (via Andy Cutler protocol)
Parasite Cleanse with herbs, Rife or Zapper
Is this overwhelming? Well, of course but if you are going after big bugs in the gut, it's best to do this the right way and this is what most of us who are on our healing journies on CureZone have had to uncover and ultimately do for ourselves.
