Because I started having Arthritis showing up while I was waiting for my zapper (I didn't order one right away but did the herbs---I wanted to do a bit more research. And since any of the 'autoimmune' system diseases are parasites which the body is attacking (not you) you'll have that kind of problem. If fact, if the cartel says 'causes unknown' it means it's parasites and they are hiding that.
I've never claimed I had huge worms. I've never even seen a worm come from inside of me. I go with the SYMPTOMS that Dr. Clark described as parasite infestation. My arthritis, went away shorty after I got the zapper and started Zapping.
The anti zapping crowd, of which you seem to be part of have made a morass of confusion about the whole parasite 'recognition' issue. It isn't that hard, nor obvious except for SYMPTOMS, eh??
And being so irritable and cranky and negative if you can't make me lie to please you--are you really the best representative to be here either??
