Because of its potent anti-inflammatory properties, Arnica can relieve the pain associated with Carpal Tunnel Syndrome (CTS). CTS occurs when the very small opening below the base of the wrist develops inflammation. It causes tremendous amounts of pain. Studies have found that people with Carpal Tunnel who apply Arnica find relief from their pain and inflammation, and it has also been found to prevent many from undergoing surgery that is meant to relieve their Carpal Tunnel pain.
