Zostrix Original Strength Arthritis Pain, Capsaicin Pain Reliever, Odor Free, 2oz Tube

Original Strength Zostrix uses the natural power and heat of the chili pepper to relieve even your toughest muscle and joint pains. It works by blocking your body's pain messenger, Substance P. Found in the nerve cells, Substance P is responsible for transmitting pain signals to your brain. Zostrix blocks it, and the pain.
