I am an alternative therapist and what I "saw" is that you have to put things into your body that will stregthen your gut flora. Your good bacteria is almost nihil and vey weak. Introduce a lot of good cultures as acidophilus and anything you can find. Try lemon balm and mint also, although they aren't anti-parasitic, somehow it will help your system to calm down and take care of itself in a natural way. Sometimes doing too much has an opposite effect too.
