If you are dealing with intestinal parasites that have not migrated to other parts of your body, there is a chance you could experience scattering if you blast your gut with strong anti- parasite herbs without preparation. Scattering means they flee to other organs, such as your lungs or sinuses, which may already have happened, or not. Im no doctor and there are others here who are much more knowledgeable. Thus said, I would start slowly and flush your colon with a series of enemas using plain distilled water. Clean your system and find out more about what your dealing with. Your stomach and other organs sometimes toss their lining which can fool you. But from there I would try a coffee enema every day for a day or two. When you know more about whats going on you might try putting the creatures to sleep with drugs designed to do that and then hit them hard with you best weapon. You will need to do some research beforehand. You will get the best results the first time you it them with something. Once they wake from their dormant state they will fight back and resist leaving the host (you).
