Peppermint essential oil: The cooling oil - The essential oils collection [Oils101]

Our sense of smell is strongly connected to our emotions and memories as our scent receptors are located next to the emotional centers in our brain, the amygdala and hippocampus. That is one of the reasons why aromatherapy is so powerful – using oils can trigger the body’s own healing process to begin, as well as soothe and calm your mind to actually allow the process to take place.  Essential oils can also interact with certain hormones, neurotransmitters, or enzymes, resulting in a specific change to our bodies’ chemistry. Oils are powerful, and they have little or no side effects.

Peppermint Essential Oil

One of the most popular essential oils, peppermint essential oil is widely used. No wonder if you consider that the scent and aroma of peppermint is familiar and pleasant to most people. The essential oil is very intense since it is more concentrated than most other steam distilled oils. When used in low dilutions, it is fresh, minty and uplifting.

The smell can easily conjure up images of the festive season, where it is associated with minty candy canes or other festive treats, or of slow summer days where you can use the oil to help cool you down. Not only in mojitos, but in a diffuser or even body mist. The oil contains menthol, which induces a cooling sensation which in turn can help cool you down and feel refreshed. One of the most versatile essential oils out there, it can be used aromatically, topically, in a diffuser and also internally (under the prescription and supervision of a medical doctor).

Peppermint essential oil is one of the oldest European herbs used for medicinal purposes. Widely used in ancient Japanese and Chinese traditional medicine, it is also mentioned in Greek mythology and have been found in several Egyptian pyramids.

The oil is derived from the peppermint plant, an herb hybrid between spearmint and water mint. The essential oil is gathered by steam distillation from the leaves and stems of the plant. The most active phytochemicals include menthol (50-50%) and menthone (10-30%), as well as menthofuran, menthyl acetate, 1.8-cineole, pulegone, perillyl alcohol, limonene, beta-pinene and beta-caryophyllene. Peppermint also contains flavonoids, the most important ones being eriocitrin, luteolin, and hesperidin.

Today, the oil is prized for its anti-nausea, cooling and soothing effects. It can help relieve sore muscles, making it perfect for the use in topical lotions, and its antimicrobial properties makes it suited for use in toothpaste and mouthwash.

Benefits and uses include treatment of the symptoms of asthma, colic, exhaustion, flu, flatulence, headache, nausea, scabies, sinusitis, vertigo.

Shown to be effective in the treatment of irritable bowel syndrome (IBS), peppermint essential oil is able to reduce spasms in the colon, which relaxes the intestines and thus helps to reduce bloating and gassiness.

Peppermint essential oil’s antimicrobial properties means that it kills bacteria and fungus, which when present in the mouth can lead to cavities and infection. The menthol leaves your mouth feeling fresh, with breath to follow.

14.   Respiratory benefits, including sinus care

Inhaling peppermint essential oil can help to unclog your sinuses and give you relief from a sore scratchy throat. It is also an expectorant, meaning the oil can help to open airways, clear mucus and reduce congestions. This makes peppermint oil one of the best essential oils for use with the flu, sinusitis, asthma, bronchitis, colds, coughs and other respiratory conditions. Because the oil is also antiviral, it can help fight infections in the respiratory tract.

Because the oil is a topical analgesic, it is a very effective natural pain killer and muscle relaxant. Especially effective to relief the pain associated with fibromyalgia, myofascial pain syndrome and other types of arthritis.

Other peppermint oil uses and how to use peppermint oil

Peppermint oil is incredibly versatile, and although it is generally thought of as being safe enough to use internally as well as externally, I would not recommend using any essential oil internally without the prescription and supervision of a medical doctor. The oil is also thought of being safe to use undiluted. Again, I would rather err on the side of caution and always use diluted.  If you want to use peppermint essential oil, here are some ways that you can incorporate it into your daily life:

Diffuse it. Add about 5 drops of peppermint oil to an essential oil diffuser for an energizing scent.

Cook with it. Add a few drops to your next recipe that calls for fresh mint, or mint essence.

Bath with it. Make a relaxing bath salt by following my recipe below.

Create a massage oil with it. Since peppermint oil soothes, cools and invigorates, it’s the perfect ingredient for massage oil. Dilute several drops in almond or avocado oil. For bonus relaxation, add lavender and eucalyptus.

Other uses include toothpaste, mouthwash, toning body lotions and conditioning bars, hairsprays, lip balms and more.

Tips on using this essential oil safely:

Peppermint essential oil can be a mucous membrane irritant. It is choleretic and can cause neurotoxicity. Avoid in the case of cardiac fibrillation and by those with a G6PD deficiency. Do not apply on or near the chest and face of infants or young children as it can cause skin irritations.

Some prescription medications and over-the-counter medications may adversely interact with peppermint oil. Enteric-coated peppermint oil supplements may cause rapid dissolving, leading to heartburn, nausea and rapid absorption of some medications.

General safety information

Because essential oils are highly concentrated they should always be used with caution. Essential oils should not be used undiluted, and should never be applied to the eyes or mucous membranes. Toxicity can occur if too much of the oil is absorbed, hence always dilute. A skin patch test is always recommended prior to using any new essential oil, or after first time use after a long break. Although most essential oils have been proven by science to work as efficiently, or even more, as allopathic drugs, they are not a substitute for medical care. Chronic conditions should not be self-treated, and you should never avoid or delay getting standard medical care. Always consult with your doctor first. Pregnant and breastfeeding women should consult with their doctor before using any natural or alternative treatment, and also speak to your doctor first before using oils on your kids. People who are epileptic, have liver damage or issues, have cancer, are diabetic, or have any other medical problem, or who suspect they might have any of these conditions, should definitely consult with their doctor first.

Shelf life and care:

Although pure essential oils do not go rancid, they do gradually lose their therapeutic value and aroma as a result of oxidation. The lifespan varies according to the botanical, distillation process, storage and care as well as manufacturer and supplier. To maximize the shelf life, store the oils in dark glass bottles, tightly closed, in a cool and dry place. Keep out of the sun. If the aroma, thickness or colour has changed, discard.
