The first thing that came to mind is what RG says that around 90% of parasites are not visible to the naked eye. Things like mold spores, yeasts, including candida, viruses, and bacteria and others which are bad for the body and do not thrive in a healthy system, but one which is toxic with metals and overstressed. Parasite cleansing is one of the steps, in my opinion on the road to health. You do not want to take any short-cuts in this regard. So, just to be safe, one should incorporate parasite cleansing on a schedule that RG recommends. If anything, doing this step, even if you do not have a large parasite load, is like an insurance policy for better health.
