Heh...I forgot one, thats just come in season-
Pod tea, aka 'polish soup' made from the pods of Papaver somniferum, the opium poppy.
Just made some earlier. Although I don't drink it for the taste, which is by all accounts, pretty fucking heinous; but the effects are good, and whats more, its totally free, if one has the patience to plant and tend a crop of poppies every year. Quite unique effects, compared to isolated morphine/codeine (by mouth), due to all the more minor constituents in the plant. Although this year almost all of my crop is going towards something with a wee bit more kick to it
Still, theres a good few kilos of pods and poppy straw harvested already, with more to come, so I certainly can spare a little for a few pots of tea.
