Steep herbal tea in hot water. In a separate cup, pour gelatin, salt, and cream of tartar. Add cold water to gelatin mix and whisk with fork until evenly dissolved. The mixture should start to bloom, becoming a gooey mass.
Once your tea is steeped, remove the tea bags. Pour into the cup with gelatin mixture and whisk with fork. It will take a minute or two for it to dissolve. Add liquid stevia. Taste to make sure you like the flavor (otherwise you won’t want to eat them!)
Place your silicone molds on a flat tray. Carefully fill your molds with a spoon or dropper. I filled six whole molds with mine, but the kids ate the gummy bears before I got a chance to take pictures. Once your molds are full, place them in the refrigerator. If you don’t have silicone molds, you can simply pour into a Tupperware or Pyrex dish and let set.
Remove from the fridge and take out of the molds or, if you used a dish, cut into small squares. Store in the fridge in an airtight container for 1-2 weeks.
