If modern medicine is so confused about the extent of the problem with parasites, and if the tests for parasites are so inconclusive, and if the treatments for parasites are not 100% effective, and if some symptoms of parasites can be explained by other factors, how can anyone know "the truth plain and simple" about the effect of parasites? What would you use as a guage to determine if you need to do a parasite cleanse? And how does one know if the icky feelings they have when doing a parasite cleanse are actually from die-off or if they are from the cleanse itself? I mean, is it possible that some people may have an ill effect from the cleanses themselves and not from parasites dying off? I'm not trying to be argumentative here, just trying to have a better understanding. If a person is feeling well, would you still recommend that they do parasite cleansing? And why?
