Aromaland Essential Oil - pure, therapeutic grade, offered in various sizes. Peppermint essential oil (Mentha x piperita) is steam distilled from the leaves of American grown plants to create a cool, refreshing, minty-sweet scent. The aroma can be very useful to help open breathing, boost alertness, reduce indigestion, and calm a headache. Topically, it has a strong cooling effect that can help with aches and swelling. Always dilute essential oils with topical use. Diluting to 2% equals about 10 drops of essential oil per ounce of carrier oil. Carrier oils help improve the safe use and effective absorption of essential oils. Avoid the use of peppermint essential oil with pregnant or breast-feeding women, young children, and those with certain medical conditions. Discontinue use if any irritation occurs.
