if you already were able to destroy some parasites with it then it works, just remember do not stop after 7 days as HC recommends - whatver she came with was many many years ago and these days parasites need longer treatment with stronger herbs or other methods
this is my own experience - in the beginning I followed Hulda Clark 's protocols twice, it always seemed to be helping a little but then after I finished I was back to where I was before, even the maintenance dose she recommends is not enough based on my experience
I think you can continue taking whatever you've got but increase the dosage and take it for way much longer, some herbalists suggest 60-90 days in order to completely rid yourself of parasites
