About the only teas I drink these days are homemade chai tea with cinnamon sticks, ground cloves, ground cardamom and ginger with a little nut milk and honey added. Or just ginger tea by steeping fresh ginger and adding honey. I stay away from commercial teas. I also like drinking raspberry tea with a little honey or maple syrup.
For "coffee" flavored drink (I was never a coffee drinker), I mix about a tablespoon of raw cocao powder and some grade B maple syrup, then add warm water. Tastes yummy and my kids drink that instead of mucus-causing hot chocolate (if made with milk).
