I love my Yerba Mate. Great stuff - one or two bags can be reused all day long, from hot tea in the morning to iced tea in the afternoon. The Brazilian kind (Nativa, green box) is peppery and the stuff from Paraguay (Guayaki, yellow bag) has a lighter, grassier taste.

I drank it through Induction and OWL (three months now) with no problems; however, it has over 100 active phytochemicals and some people might be sensitive to it.

Some people are sensitive to psyllium as well.
