Most people have no symptoms and are then shocked when they see dead parasites floating in their toilet.
I zap every morning driving to work and then zap again driving home in the afternoon.
I have also done several parasite cleanses and I have gotten different results with each one. But, I always saw parasites.
So, I would tell you to do both. The cleanse is SO EASY and because Dr. Clark preaches that parasites cause cancer, wouldn't it make more sense to do the cleanse than risk cancer?
