Because cinnamon is made from the bark of tree it’s mostly cellulose which is an insoluble compound. Once a spoon of cinnamon goes into your mouth it basically coats the inside of your mouth, this dries it out and it becomes difficult to swallow the cinnamon and because you can’t swallow it cinnamon then produces a very unpleasant burning sensation. Of course, you still need to breath and as you inhale the cinnamon powder gets into your throat and lungs basically blocking the air passages.
