colloidal silver

hi there, i'm planning to begin a parasite cleanse soon. i'm going to complete another Bowel Cleanse first (already did one a couple months ago) but feel i need to do another one. I think i will likely try humaworm. my question is in reading lots of posts it seems that it's necessary to do "in between" maintenance to keep the worms from repopulating - has anyone considered Colloidal Silver as a maintenance supplement to take in between parasite cleanses or will this not work? thansk for your input.
