Capsaicin (noun, “Cap-SAY-ih-sin”)
This is a molecule that is found in chili peppers. The chemical’s official name is 8-methyl-N-vanillyl-6-nonenamide. When capsaicin comes into contact with the tongue or skin, it causes a burning sensation. Plants use capsaicin as a defense, to keep mammals from eating the pepper fruits. But people who eat peppers often find that burn adds extra allure to nachos, pizza and other foods.
In a sentence
It might burn a little, but capsaicin on the skin can also soothe pain by starting a chemical cascade that helps the brain ignore the hurt.
