Why do chillies burn on the way out?
When we were eating chillies earlier whether the burning sensation is confined just to the mouth or elsewhere in the body?
Chris Smith answered Vinnie's spicy question...
Chris - And the answer Vinnie is that anyone who has had a hot curry knows it is not confined purely to the mouth area. And the reason is that the nerves that sense the burning capsaicin in chilli peppers, they are present in your mouth and the other place where you have surface epithelium (your skin), and that’s your bum. So, you do feel it on the way in, and on the way out.
