This will stop the re-obtaining of new critters, but won't kill the critters already present. Only herbs or drugs do this. It is the uncooked produce that is the usual source for our problems with Protozoan parasites, and Helicobactor pylori too. Although babies are often born with the critters their mother has in the womb or vagina.
