Crude Mentha Oil, commonly known as CMO, is the primary essential oil obtained through the steam distillation of the leaves of Mentha arvensis. It is the base material from which menthol and other mint derivatives are produced. With a strong, penetrating minty aroma, CMO is widely used in the manufacture of menthol, flavors, fragrances, and pharmaceutical formulations. Its natural freshness and purity make it a key raw material in the mint industry.
