Dave,
Go to Clarks web site and you can read a lot of exerps from her books. She also has the plans and parts list to build a zapper. If you have any electrical experience or know someone who does, It's not too hard to build. The parasite herbs she prescribes took about 3 weeks to work. 6 months later I used the zapper and my nose would start to heal within about 4 days. The Liver Cleanses were the kicker to keep it away. Recently, I had a small bump on my nose for about 3 weeks that I suspected was rosecea returning. I used the zapper and it went down within the week, I also did another liver cleanse at the end of the week. I would get a tingle in my face when the rosecea starts to return, does this happen to you or anyone else who is reading this?
