Pure stevia is not artificial, but the verdict is still out on safety. It seems to be OK... for now. I use it, though I try to use honey as well.

The stevia whole leaf has been used for centuries in teas on Brazil. It has been used as an artificial sweetener in Japan for decades accounting for around 40% of the sweetener market there. Weirdly, I always bought it labeled as a dietary supplement in the US before the FDA approved some extracts as food additives.

That was my first thought too, I use stevia in almost everything.
