Theraflex is an extra strength, deep penetrating, herbal topical pain reliever that contains capsaicin (Cayenne Pepper Extract) that increases blood flow, and contains mints for cooling, and a penetrating ingredient to deliver it deep into the tissue. It is a "natural" Ben-Gay.
Theraflex works by cooling inflamed tissues by pushing lipids from the site of inflammation, thus reducing swelling and releasing beneficial endorphin's in the brain. These endorphin's are the body's own natural pain blocking substances. This cooling phase is followed by a heating effect caused by the capsaicin. The capsaicin renders the skin and joint tissue insensitive to pain by depleting the re-accumulation of the chemical messengers that carry pain sensations to the brain.
