Yerba máte seems to be becoming popular, but I am having trouble untangling just what it is. From what I have read, it is a South American herbal tea drunk communally - i.e., hot water is added to the herb as it is passed around a group, gradually getting weaker and smoother. However:
Some sites claim there is no caffeine in yerba mate, others claim the naturally occuring "elements" are so similar in chemical content that to consider it anything else than caffeine is, to quote, "fooling yourself."
Moreover, some sites say the "caffeine-like" content is significantly stronger than that of caffeine in black coffee. (Though it is mitigated over time by the addition of the above mentioned water.) Others say that it has less "caffeine-like" content and is no different than drinking weak coffee or strong tea. I have also seen the term "yerba extract" mentioned on weight loss/body building sites and want to stay far away from that sort of thing.
Lastly, I live in an isolated rural area without access to any real tea stores. Anything I should look (or look out) for if I want to try some of this mail order? Should I try to find it "pure" or flavored with lemon? (I understand Tazo sells it with lemon; Celestial Seasons sells it as part of its morning awake tea) Is yerba mate the same as "green yerba mate" tea mentioned at the stashtea.com site?
Thanks for any clarification of this subject - I only recently stumbled on this group and apologize if the subject has been talked to death.
