Peppermint EO is one of the most frequently added ingredients to my aromatic blends, especially when they need to provide fast relief.

This is not the most holistic of EOs, but it offers a rather impressive symptomatic response that makes it easy to act in place of many drugs.

I’ll share with you here the uses of this essential oil whose effectiveness has been proven scientifically, for once.

This is another kick in the argument of those who want to go after this science, and state that there is no evidence of the effectiveness of essential oils, as if it mattered when the product in question is not a risk factor.  

If you wait for this scientific certainty to “convince” you, here are 15 good reasons to get you there.

Today, modern scientific research reveals an abundance of potential health benefits associated with the use of various components of the peppermint plant, including aroma-therapeutic, topical and internal applications.

Most of the research done on peppermint on humans to date indicates that this herb is of great value in the treatment of gastrointestinal disorders, including:

Irritable Bowel Syndrome – Since the late 1990s, it has been discovered that enteric-coated peppermint oil capsules work very well in the treatment of this increasingly common disorder. But we also have good results by diluting a few drops of this EO in a base oil that is massaged on the belly. This local application can treat both children and adults.

Colon Spasm – Peppermint oil has been studied as a safe and effective alternative to the drug Buscopan for its ability to reduce spasms during barium enemas.

Gastrointestinal Disorders – Peppermint has been shown to improve gastric emptying, suggesting its potential use in a clinical setting for people with functional gastrointestinal disorders.

Functional Dyspepsia – A study from 2000 published in the journal Ailment Pharmacology and Therapy found that 90 mg of peppermint oil and 50 mg of caraway oil improved the symptoms of gastric reflux by 67% of those tested. It must be said that peppermint is part of what I call the oils of the stomach and that, moreover, it stimulates the production of gastric acid (what we need in case of dyspepsia).

Other studied applications show us that:

Nipple Pain and Damage Associated with Breastfeeding: A 2007 study found that peppermint water prevents nipple cracks and nipple pain in nursing mothers. Personally, I would not go to put peppermint EO on my cracked skin! Breast milk is enough…

Tuberculosis: A 2009 study showed that inhaled peppermint essential oil could quickly reverse tuberculous inflammation, leading the authors to conclude: “This procedure can be used to prevent recurrence and exacerbation of pulmonary tuberculosis.” Many essential oils do the same. But we will know that peppermint is known for this…

Allergic rhinitis (hay fever): A preclinical study conducted in 2001 found that peppermint leaf extracts inhibit the release of histamine, indicating that it may be clinically effective in relieving the nasal symptoms of allergic rhinitis. Tip: add some Scotch pine and tarragon EOs.

Pain associated with shingles (post-herpetic neuralgia): A case study in 2002 found that topical treatment with peppermint oil resulted in almost immediate improvement in symptoms associated with neuropathic pain associated with shingles; the therapeutic effects persisted throughout the 2 months of follow-up treatment. The best thing to do, however, is to add geranium EO! Geranium knows how to fight the herpes zoster virus, source of the shingles crisis. To mix with peppermint EO in a base of coconut oil, then to massage on the targeted area.

Memory Problems: A 2006 study found that the simple aroma of peppermint improves memory and increases alertness in humans. However, it works better by mixing it with rosemary EO.

Chemotherapy Induced Nausea: A 2013 study found that peppermint oil was effective in reducing chemotherapy-induced nausea, and at a reduced cost compared to standard drug therapy. It must be noted that the danger is to associate nausea with the smell of peppermint once you finish with the chemo. That’s why the good alternative is to prefer bergamot mint EO (mentha citarta).

Prostate cancer: Preclinical research indicates that peppermint contains a compound called menthol that inhibits the growth of prostate cancer. Good to know… to be diluted and massaged on the belly.

Radiation Damage: Preclinical research indicates that peppermint protects against DNA damage induced by radiation treatments and cell death. In application, massage using a very fat base like coconut oil, before and after the treatment.

Herpes simplex virus type 1: Peppermint has an inhibitory activity against herpes simplex virus resistant to acyclovir 1. Even better if it is associated with geranium EO!

Dental Cavities / Bad Breath: Peppermint oil extract was found superior to chemical mouthwash, inhibiting chlorhexidine Streptococus mutans, driven by the formation of biofilms associated with dental cavities. This may explain why peppermint leaves were used in the Middle Ages to combat halitosis and whiten teeth.

Mouthwash: in 1/2 liter of water, add 3 drops of peppermint EO, 2 drops of cinnamon EO and 1 drop of clove EO. Shake well and use as a mouthwash. You will forget all about Listerine!
