I've heard some say that this means it most likely is safe but others say that it is 'no evidence at all' that it's safe.
I mean if it caused acute negative effects it is easy to tell but what about if the negative effects were delayed like incidence of cancer? Would it ever be known that the traditional medicine was the cause?
So I would like to open the discussion as to other people's opinion on this matter regarding specifically the liklihood of knowing long term negatives if any of a traditional herb with several centuries usage.

. I have seen people react extremely bad to drugs that other people have taken with no side-effects and people develop side-effects after years of use when they had none before, (I'm specifically referring to prescribed drugs), and these are drugs that have supposedly been rigorously tested.
