lol, was afraid after I read your post that the muscles on my tongue were dead. So I just came back from tasting a teaspoon of it again, and your right I do, it's at the back of my mouth and it did TINGLE. I hadn't noticed it last time, maybe because it was such a tini tiny bit that I drank, the next day I put the teaspoon of echinacea in a glass of water and hadn't noticed any sensation, but now that I had the full teaspoon on its own I DID NOTICE IT. Your right, it must be a strong batch. Maybe I managed to do something properly for once,lol. Thanks Tom
