Peppermint (Mentha piperita) is the second most popular essential oil in the United States. Its fresh, menthol aroma carries energizing benefits to carry you through the day, from helping you wake up in the morning to relaxing your tired feet at night. It’s ideal for travelers on long trips, providing refreshing, energizing effects on a long journey. Peppermint essential oil blends well with lavender, rosemary, lemon eucalyptus, tea tree, lemon, and sweet orange essential oils. In addition to body and massage oils, peppermint essential oil is often used in air fresheners like air mists and diffusions.
