CAYE warming balm bases its effect on capsaicin. Capsaicin comes from the dried berries of the cayenne pepper plant and is absorbed directly into the skin after application. It inhibits the transmission of pain via nerve endings and, at the same time, irritates the skin in a healthy way, leading to an increase in blood flow with the resulting sensation of pleasant warmth. The improved circulation transports oxygen and nutrients to the muscle tissue, boosting performance.
