I prefer my blueberry tea iced. Just a warning-when you add milk to blueberry tea, it curdles--at least the brand that I have.
I've recently fallen in love with Bigelow's Vanilla Caramel (also available in decaf). It's very sweet (or reminiscent of sweet) with no sweetners/calories. I'm trying to watch my weight, and it takes care of my sweet tooth everytime!
I have a student I tutor whose mom owned a tea room. She always has the best teas! It's such a luxury for her to make me a cup when I teach.
Parsley tea? I guess you could make tea out of almost anything, but who wants to?
