At the heart of this homemade salve is cayenne pepper. This unassuming spice contains a remarkable compound called capsaicin, which is renowned for its ability to provide targeted pain relief when applied topically. Capsaicin works by blocking the transmission of pain signals from the affected area to the brain, offering soothing respite from a variety of discomforts while the beeswax helps to moisturize and soothe the skin.
