From what I read in the book the only parasites that have been seen were when the initial doses were quite high and the person treated vomited very quickly the worms came out with the vomit. I believe that the worms are attacked just like the Mold, Virus, Yeast and Bacteria and toxic plaque. They are touched by the chlorine dioxide and exploded at a cellular level. It seems that it takes an inerchange of pathogens with Miracle-Mineral-Supplement (as chlorine dioxide) to effect this explosion when this happens the explosion produces water and salt from the Miracle-Mineral-Supplement and what ever pathogen it encounters. This is how it works with toxic acid deposits and Mercury or heavy metals as well. I don't believe you will see any worms, flukes or what ever other parasite in the bowel movements. I hope what I have read is correct. MW
