I don't know if it will "get rid" of a whole bunch of parasites. I know that the only time I've ever seen parasites is when I've done this. I also know that herbs, etc. do one thing - but the Sea Salt cleanse helps keep you GI tract in an inhospitable state for parasites. Everything is moving and not blocked, and parasites thrive on a constipated GI tract. Plus, everyone says you should do bowel cleansing when you're doing parasite cleanse or Liver Flushes - well, I find the Sea-salt cleanse just 'emptifying'!
