What spice in Asian food makes me sweat and my nose running? What spice in Asian food makes me sweat and my nose runny?

I highly appreciate it in those cases where I've caught a common cold or anything the like, just when the original impact is too low so that my body fails to give those reactions by default. (And it doesn't feel wrong even when I feel very healthy otherwise. Just, somehow, purgative.)
Some health food stores will sell Cayenne Pepper capsules for this very purpose. Some people find that taking a couple will help them sweat out colds and flu. Never tried myself, but I agree there's nothing like a dish packed with heat to clear out the sinuses.
