Capsaicin

Capsaicin is a natural compound found in chili peppers that gives them their spicy heat. When consumed, it activates pain receptors in the mouth and tongue, creating a burning sensation. Interestingly, capsaicin also triggers the release of endorphins, which are the body's natural pain relievers, leading to feelings of pleasure or a "spicy high." It has been used in topical creams for pain relief, as it can desensitize nerve endings over time. Besides culinary use, capsaicin has potential health benefits, including boosting metabolism and aiding in weight management.
