It's my profession. I think I understand any "problems" there are, and compared to say, epidemics that used to kill as much as a third of the human population in a single outbreak, I regard the "problems" as trivial.
And again, I might know something about it, since I live and work there.
I've worked my ass off, and perhaps you think I should feel overwhelming guilt at wanting to be paid for what I do - and I'm hardly independently wealthy - but as a person who has spent thousands of hours in the primary scientific literature as part of my work, I really haven't seen any worthwhile publications - and my life is very much involved with reading publications in the primary scientific literature, out which the OP here comes - that suggest that taking medicinal plants as opposed to controlled pharmaceuticals is a safe or sane practice.
But increasingly we live in a world dominated by libertarian values - as much as I regret it and as much as I think rugged individualism is garbage - and we have to live, or die, because people object to vaccines and pharmaceutical products.
Eat medicinal plants at your own risk if you wish. I would never agree to let anyone I love do so if I had the power to do so, but to each his or her own.
I'll die soon enough myself; I'm old, but I would have been ancient in the 1930's, and the fact that I've lived this long is because I've taken a scientific approach to my health.
