Ingredients (from the site):
Rooibos (red bush)
Tetley Red Tea is caffeine-free and Tetley claims that it "contains qualities that relieve allergies, ease digestion and help increase iron absorption". I have no idea if it helped me with anything, but this was a nice tea. Tetley also says that "it also contains minerals that promote healthy skin, teeth and bones."
I'm no scientist so I have no idea if those are true or not. I drink tea for the feeling and taste (also because I dislike drinking water). Overall, this satisfied my tastes and I am considering buying more after I finish some of the 58 tea bags I bought today.
