As for caffeine in herbals, Yerba Mate is the only herbal that can claim this. Some vendors claim that Maté contains matiene a special variant on caffeine called mateine. Put simply, while it makes for a good Maté marketing tool, there is no scientific basis for this claim. That said, people often report a different feeling from the caffeine in Maté vs. the caffeine in tea or coffee. These differences result from the two other caffeine like compounds in Maté. Caffeine is a xanthine, a category of compounds that work as stimulants in the body. Maté contains three of these xanthines: caffeine, theobromine and theophylline - each with their own stimulative effects. In short, this "Herbal Tea" packs quite a stimulative punch!
No need for citations, wikipedia agrees with and ref's everything you wrote. Either way though, it's great!
And yes, yerba mate. I remember my bodybuilding days when I searched up and down for this stuff as many said it's unbeatable for the 'cut' (weight loss after weight gain). However, Chocolate also contains the same xanthines (methylxanthines) Caffeine, Theobromine, and Theophylline. Perhaps that same 'feeling' consumers of Mate get is the same reported from proper cacao based chocolate. I remember a lot of testing/study being done on pure dark chocolate and bodybuilding before I 'left' primary because of it's anti-oxidants but also because of it's 'unique stimulant effect'; much like Mate.
Also, it may be interesting to note I had a Drugs and Behavior Psychology/Chemistry professor recently that seemed to have the belief of Coffee containing Caffeine, Tea Theophylline, and Chocolate Theobromine. And that, although the corresponding chemicals may not be the primary active ingredient, it's interaction with the primary substances (Caffeine, in the case of Tea, for example) would result in different (and far more beneficial) response. Mind you, I've had a hard time finding claims confirming this. However, there's no doubt to the substantially different effects of Coffee vs. Tea vs. Chocolate vs. Mate vs. etc.
