Menthol crystals are naturally produced through Peppermint (Mentha arvensis) essential oil extraction. Menthol is the solid constituent this oil which gives the oil it's characteristic odour.

Menthol crystals are cooling, refreshing and have a strong peppermint perfume. They are used in perfumes, throat sprays and lozenges, analgesic balms, lotions, medicated creams, mouthwash, gum, foot sprays, pain relief or cooling body products, shampoos, conditioners, and are especially useful in liniments that help relieve muscular aches, coughing, and respiratory problems.

Menthol crystals are easily solubilized in slightly warmed fixed oils, making it easily added to ointments, salves and balms. Menthol is used in pharmaceutical formulations for its analgesic and cooling effects. It can be used in cosmetics containing peppermint to boost its cooling and freshening effects. It is also widely used in the confectionery and flavoring industries.
