Recipe Analyzer doesn't recognize STEVIA, what should I try instead?

I tried putting in 4 tsp stevia, didnt recognize that, so then I tried just "stevia" but still getting a red flag.  anyone know of another term?

It's sometimes called Sweet herb but that didn't get any results in the search either. anycmw's answer seems sensible. I started using stevia this past year. How do you use it? Have you baked with it yet?  So far, I've only added it to oatmeal and other morning cereal. I bought a plant at the farmer's market last spring and grew and dried it myself because I couldn't find any in even health food stores.

Thanks amy,  I decided to just leave it out because it has 0 calories and 0 nutritional value.  Was frustrated as well because I couldnt find low fat ricotta cheese and low fat cream cheese on the data base that match the values of the products I bought.  data base values where higher.

Tissa I use stevia the same ways you mentioned, and I use it for desserts.
