parasites keep returning? Same for all of us who really have them that is. Unfortunately yes I see current drugs now as a control rather than cure. The meds just never really got to the stage "proven to cure" if you look at all the available evidence. They are effective at control (until the resistance sets in that is) but that's it. In the end we need more advanced drugs and for the medical community to acknowledge their mistakes. But hold on! They still confused about cholesterol and saturated fat issue and we are talking about complex immunology and parasitology over here LOL! Never say never but here never LOL!
