There are some very affordable, very effective products out there. You need a parasite cleanse with a blend of herbs that will destroy ALL parasites (including the microscopic ones) cleanse your system of parasite toxins (their feces, urine, etc.) AND help your digestive system rid your body of these unwanted guests. A 30 day program is sufficient. A Colon Cleanse is fine, but you need those 10 parasite killing herbs for parasite removal.
