I don't think being hard on garliccures is necessary, I think there can be some effective cures out there but I would agree that pharma's are the best choice.
Simarouba, amargo and cat's claw can be a powerful combination - I took all three of these for a long time (at least 4 months) they did not eradicate my situation but I am not dealing with e histo but more likely microsporidia which is a different protozoa altogether. There are plenty of ayurvedic meds which have been shown to clear these nasty bugs as well.
