I think you can better help us if you find a tested cure that has a real high percentage of success. If you find something like that, please share.
There are way too many suggestions when it comes to cures against parasites and most of the time they are not tested against the specific parasite being discussed. One can spend the rest of life trying different suggestions without getting better. Using natural remedy is not necessarily safer. Herbs also have risk. Some herbs can kill and create problems. It might also be possible to create a super bug if one tries too many wrong or weak medicine.
