I wonder, who among you has had experience with giardia? A friend's friend had it a while back, was 'diagnosed' and given some allopathic drug, which she decided not to take. I think it must have been an antibiotic. She is past/over the symptoms now, but a bit concerned:wants to know if there is something she ought to take (meaning something natural/alternative)to strengthen the system. Would she want to be doing more than having good probiotics,maybe cultured vegetables? I don't think she's very aquainted with the cleanses and so on that many of us are, around here.
