I had a few requests, and wondering myself, Stevia is natural, I used to work in a garden and nursery center and have tasted and sold this wonderful little plant personaly, and doesn't have a sugar responce in diabetics from what I understand. I am sure that it can be had as an organic extract. BUT! A little does go a long way, even in its natural (leaf) state it would make a person pucker because of it's sweetness. Stevia gets a bad rap because of it being marketed as a processed sugar substitute similar to splenda, but it really is an herb.
I would actualy prefer to have my e-liquid sweetend with stevia if it were certified as an organic extract. It tastes wonderful. also I don't remember if I have seen this somewhere or not, but while you are Organic, why not Kosher, and Vegan..? just a thought.
