A Menthol Gel is used to treat minor aches and pains of the muscles/joints (such as arthritis, backache, sprains). Menthol is known as a counterirritant. It works by causing the skin to feel cool and then warm. Menthol provides a cooling sensation when applied to the skin, which helps relieve pain in the tissues underneath the skin. Menthol, also called peppermint camphor, has a strong minty, cooling odor and taste. It is an organic compound that can be obtained from peppermint and other mint varieties. It can also be man-made or synthetic. The Menthol Gel is made for use in medical purposes.
