I remember eating a chilli in india which was extremely hot, unsure of what it was exactly, but quite small and green.
quite a strong mouth burning sensation but also extreme head rushes, which was followed by feeling very light headed and for the next few days bad rash all over my body.
I get both buzz and burn, sometimes one at a time, also i find myself putting it on EVERYTHING, i have to stop myself as i eat it too much hehe
