Description Capsaicin molecule
Capsaicin is the substance responsible for making peppers, chili peppers, and the like so spicy. You can also find it in warming patches that you can apply for back pain (usually caused by spending many hours hunched over in front of the computer) to relieve the pain (although often it only makes it worse - the stuff is really hot).
If you enjoy eating spicy food (or suffer from chronic back pain) ;) then show it best with this shirt :)
