i took 300mg twice a day but of extract not whole herb, so in theory at least 900 twice a day of substance. for 2 years. took this with GSE, polyporous, artemisia, etc
i relapsed on it and ended up on antibiotics.
this is the problem with herbs, im never sure im taking the right dose , the right herb quality... extract no exrract, 5:1, 3:1 , etc.... too many variables and u end up diacovering 2 years later u were doing someth wrong
