It's best to use a blend of herbs for parasite removal. parasites can wreak havoc on our bodies. The toxins they create (their feces, urine, etc.) do as much if not more damage than their taking of your nutrients. You need a herbal blend to #1 kill the parasites, larvae and eggs #2 to sweep your body clean from the toxins and finally the blend needs to have #3 digestive and bowel support as all parasites and toxins are expelled through this system. parasite destroying herbal blends are available all over the net. Make sure you carefully read the amount of herbs in the product and how each one works to cleanse parasites. Some are quite expensive, while others are very reasonable. I hope this was somewhat of a help.
