You may have to try to take higher doses. Maybe the product you're using isn't strong enough. I think you need to find an aggressive parasite cleansing product. Did you do a Colon Cleanse first. If not, you may be constipated and that explains why you aren't getting results. Realize too that some parasites are microscopic and not seen w/the naked eye. If your rectum burns or itches after a bowel movement and you know you haven't eaten anything hot like cayenne pepper, chances are you have microscopic worms.
