I don't think that I have to go anywhere to get parasites. I do think, however, that parasites are 'regional' to some extent and want to ensure a proper cleanse for all avilable types of said parasites(I know about the flukes how hard they are, and about the brain and pancreas problems). I am only confirming my need for a cleanse, and expressing that I don't want my son to get anything passed to him in the way of toxins purged during a cleanse.
