You can still get rid of them but it's not easy. I recommend colonics but this is expensive and it will stir things up. Most people have parasites and just don't know it. There are a number of different things parasites don't like, including garlic, pineapple, apple cider vinegar, tea, etc... Using these together with Wormwood is helpful especially if you catch it early enough. The bigger ones don't go down so easy.
