I think it more what they DO to the stevia extracts in the processing rather than that plant derivative itself.
So, the Stevia my wife grows and mushes up is okay? Unfortunately, it is not as sweet as the processed stuff, and there isn't enough of it.

They have to use all kinds of strong alkali chemicals to extract the sweet elements from these plants. I’m convinced that these pose the real danger.
