Peppermint essential oil is another popular oil. Many people use peppermint oil as a natural pick-me-up as it has such a fresh, uplifting scent. It is also used for headache relief by rubbing some on the temples and breathing deeply.

Care must be used with peppermint essential oil. It is a very strong oil and must be kept away from the eyes as it will make them burn and tear. A small area of skin should be tested for sensitivity before using topically (always have olive oil or some other sort of carrier oil available to wash an essential oil off with; never water).

Peppermint essential oil is great for adding to water. It provides a refreshing flavor and helps support digestive function and reduces nausea.
