Thanks RR for the herbal notes.
The Stevia issue might be related to the chemistry as they try to extract the active ingredient, stevioside.
I couldn't see a problem with eating the whole leaf.
First Nations communities in the PacNW still have medicine women and medicine men.
They still use their herbs and they still teach the younger generation. Good.
As it is turning out, many of the herbs are effective for the purposes claimed.
Just how many generations over how many thousands of years did it take
to figure out how to prepare what worked and what didn't???????
More and more, I see books printed about those old ways and plants.
I buy everything I can find.
