Even if you’re not familiar with essential oils, you’re probably familiar with menthol and regularly use products that contain it. One of the most widely known and used terpene compounds is menthol, a monoterpene alcohol found in high concentrations in several mint species, particularly corn and peppermint. Although it is best known for its skin cooling and respiratory benefits, its surface cleaning, body system support, and pest control properties have also been extensively researched*.


Menthol is one of the oldest known terpene compounds. There is evidence that it was identified in Japan in the first century AD and it has a long history of use in traditional herbal preparations. In the Western world, it was first isolated in Germany in the late 18th century. Today, because of its many advantages and applications, it is one of the most isolated and synthetically produced terpene compounds. With demand far exceeding natural supply, over 3,000 tons of menthol is produced synthetically for commercial use each year. Menthol is an active ingredient in numerous products ranging from aftershave to topical muscle cooling lotions. It is also used extensively as a flavoring in pastries, chewing gum and oral hygiene products, and in perfumery it is often used to emphasize floral notes.


Clinical and experimental research shows that topically applied menthol has a soothing and cooling effect on the skin. The mechanism behind this effect is the unique ability of menthol to trigger specific receptors (TRPM8) in the skin that are cold sensitive. This property is why Peppermint is one of the primary ingredients in the doTERRA Deep Blue® line. If you use little Deep Blue Soothing Blend or Deep Blue Rub, dilute 1-2 drops of Peppermint in lotion and apply this mixture to muscles and joints after a workout, or use this mixture to complement a soothing massage. For overheating, add a few drops of Peppermint to a cold water compress or foot bath to cool down. The cooling sensation is also great when applied to the scalp: add 1-2 drops of Peppermint to your shampoo or conditioner.

The skin-supporting benefits of menthol are not limited to its cooling effect. Clinical and experimental research also suggests that menthol has cleansing properties that may help reduce the appearance of blemishes. Add a drop or two of Peppermint to your favorite moisturizer and apply daily for healthy, glowing skin.

Peppermint is often referred to as a “vitalizing” essential oil, and by researching it, it’s easy to understand why. Clinical and experimental research suggests that aromatic use of menthol may have a sense of soothing and cooling effect on the respiratory tract, promoting the feeling of clear breathing. One of the most popular ways to experience Peppermint oil is right before you do something active. Put a few drops in your palms, rub them together and inhale directly for an energizing boost and to support the feeling of clear breathing.

The menthol not only cleanses the skin, but it can also boost the power of your household cleaners. Experimental research suggests that menthol has cleansing properties that may support its use as a surface cleaner. If you’re tired of the same old citrus-based DIY cleaner (although limonene itself is a powerful cleaner), try adding 10-15 drops of Peppermint to a glass spray bottle of water and white vinegar the next time you attack the grime on your kitchen counters.

Menthol is used extensively as a flavoring in candy and even toothpaste, but the internal benefits far outweigh the powerful minty taste. Experimental research suggests that menthol taken internally may support digestion.* Experimental research also suggests that menthol may promote healthy cellular function when taken internally.* Take for digestive support 2-3 Peppermint Beadlets before a large meal or as needed, or take one to two drops in a Veggie Cap to relieve the stomach every now and then.* In the same way, every morning try 1-2 drops Peppermint essential oil to add to your chocolate Slim & Sassy® TrimShake for your daily cellular support.*

Its use in mouthwash and toothpaste is not strictly for taste, clinical research suggests that menthol can help maintain a clean, fresh smelling and healthy mouth when used as part of a regular hygiene routine. Add a single drop of Peppermint to your toothpaste while brushing your teeth every morning and evening, or place a single drop in your mouth when you need a quick breath freshener.

One of the lesser known uses of Peppermint is as a natural insect repellent. Experimental research suggests that menthol may act as an insect repellent when used aromatically or applied topically. In the summer, Peppermint can be applied around windows and doors, or diluted topically and applied to arms and legs before a day trip to naturally repel insects.


One of the earliest identified monoterpenes, menthol, is also one of the most researched. Whether for skin soothing, respiratory or digestive support, skin or surface cleansing, repellent or just a quick breath freshener, reap the benefits of menthol with CPTG Certified Pure Therapeutic Grade® Peppermint essential oil.*
