Thanks and I agree - this place is refreshing!
So - that is a good question and made me look RED ROOT up again because I can't remember what I read last time.
The herbal component is actually derived from the hearty, deep red colored roots of a shrub called "wild snowball" and was substituted as tea during the Civil War... so there's a little bit of history for you.
This Gaia brand one of the brands that places like Whole Foods sells - usually in the $12-14 range for 2 oz.
