The ThermaCare Neck, Shoulder and Arm Rest with 9 pads, which are specially tailored for these areas, helps to relieve tension in the neck, shoulder and arm. All ThermaCare patches contain natural ingredients that react with air to produce heat (when the airtight packaging is opened). The self-heating plaster can be used for chronic and occasional pain caused by muscle tension, strains or arthritis. After a half-hour warm-up time, the patch warms the affected area reliably for 12 hours at around 40 degrees, all the way down. The warmth improves the blood supply to the muscle and provides it with sufficient nutrients, thus relieving tension and cramps. The plaster contains no medicines and is odorless.
Iron powder, salt, activated charcoal and water.
