Menthol crystals are cooling, refreshing, and have a pleasantly-strong, minty aroma. Menthol crystals are excellent for use in products to help relieve muscular aches and pains, coughing, congestion, the flu, and upper respiratory problems. Since Menthol crystals are so concentrated, only a very small amount is needed within products. A popular use around the Bouncing Bear office for Menthol Crystals is to drop a small crystal in a cup of warm water. The Menthol Crystal quickly dissolves and releases a strong, but pleasant aroma that, after a couple of inhalations, quickly clears clogged nasal passages. When the whole office is congested, we will also sometimes drop a couple crystals on a hot incense charcoal tablet, quickly filling the entire room with nasal-clearing vapors
