Most of capsaicin’s effects are mediated by a protein called transient receptor potential vanilloid subtype 1 (TRPV1). TRPV1 is found throughout the body, including the oral cavity, nervous system, skeletal muscles, and adrenal glands.[1][2][3] By activating TRPV1, capsaicin can create the sensation of heat (e.g., in the mouth), promote sweat release, stimulate adrenaline release, increase metabolic activity in skeletal muscles, and inhibit sensory neurons responsible for transmitting feelings of pain.[2][4][5]
