Traditional Use and Health Benefits

From ancient times to the present day, Peppermint has been used as an accompaniment to meals, to flavour confection, sauces and wines and as a soothing herbal tea.

Thought to be a naturally occurring hybrid of water mint and spearmint, Peppermint has an enduring history as a remedy for many ailments. It was used by the Romans as a cure for digestive complaints and headaches, and monks of the Middle Ages were known to use it as a tooth polisher. By 1721 it made an appearance in the London Pharmacopoeia where it was recommended for all manner of ailments including sores, venereal disease, colds and headaches.

Peppermint Benefits

Digestive Health

The power of Peppermint as a digestive aid is mainly due to the high menthol content of this herb. When taken orally, as in a tea, menthol helps relieve gastrointestinal problems like indigestion, gas and bloating. Menthol encourages bile to flow into the small intestine, where it promotes digestion by breaking down fats more rapidly. Menthol also has a powerful anti-spasmodic effect, relaxing the muscles of the abdomen and the digestive tract which allows gas to pass through the system much more easily.

Peppermint essential oil can also be used to aid in smooth digestion. Simply dilute with a pure carrier oil and gently massage into the abdomen or inhale its refreshing scent before a meal to stimulate the appetite and get the digestive juices flowing.

Irritable Bowel Syndrome (IBS)

In 2008, a peer reviewed study was published in the “British Medical Journal” that researched the effectiveness of Peppermint essential oil for the natural treatment of IBS. Four controlled trials were examined that tested the effects of Peppermint oil versus placebo on IBS symptoms in 392 patients. When the patients were randomised to the two conditions, the Peppermint oil group showed a marked improvement in symptoms, 2.5 times less symptoms than those receiving the placebo.

Food grade Peppermint oil has the power to impact the bacteria in the GI tract and prevent smooth muscle contractions by blocking calcium channels. It can also help to regulate immunity and reduce inflammation, particularly helpful for IBS sufferers. All of these effects can help reduce abdominal pain, gas, bloating, and frequency of stools.


Peppermint oil applied topically may effectively treat tension headaches, with two studies demonstrating the efficacy of topical Peppermint oil for this particular type of headache.

One study compared topical Peppermint oil to placebo and found the oil was superior to placebo in terms of headache pain relief. Another trial demonstrated that topical Peppermint oil was similar to acetaminophen (pharmaceutical pain killer) in terms of treatment efficacy. In both of these headache studies, the Peppermint oil was combined with ethanol (10 grams of Peppermint oil plus 90 grams of 90 percent ethanol). The solution was then rubbed on the forehead and temples and reapplied every 15 minutes as needed.

The menthol in Peppermint oil is both numbing and calming which can soothe an overactive nervous system during a migraine attack. The anti-sickness benefits of Peppermint can also help to relieve any nausea that may accompany an attack. Dilute Peppermint oil in a pure carrier oil and applying frequently to the temples, forehead and the back of the neck or put a couple of drops of (food grade) essential oil on the roof of the mouth to provide relief.

Oral Health

Used for thousands of years to keep the breath smelling minty fresh, researchers have found that Peppermint oil is extremely effective in killing off the anaerobic bacteria that can lead to cavities and gum disease.

A study published in the "European Journal of Dentistry" found that Peppermint oil displayed antimicrobial activities against oral pathogens, including Staphylococcus aureus, Enterococcus fecalis, Escherichia coli and Candida albicans.

Respiratory Health

The high menthol content in Peppermint make this essential oil excellent for diffusion and inhalation to reduce congestion and clear the airways. It is one of the best essential oils for colds, flu, bronchitis and asthma, with studies showing that Peppermint oil is rich in compounds that are anti-microbial, anti-viral and antibacterial.

It can also help with seasonal allergies, helping to unclog the sinuses and clear pollen out of the nasal passages.

With naturally cooling properties, Peppermint Hydrolat can be used as refreshing facial mist in the summer or at times when you are hot and bothered. It provides relief from itching and is good for insect bites and allergic reactions.

Folklore and History

Peppermint is thought to have originated in Northern Africa and the Mediterranean. In the Ebers Papyrus, an ancient Egyptian medical text dating to 1550 BCE, mint is listed as calming to stomach pains.

The Roman natural philosopher Pliny wrote of Peppermint, in particular that it stimulated the appetite stirring "the mind and appetite to a greedy desire of food." He also wrote that mint should be bound into a crown around the head in order to stimulate the mind and the soul. Pliny, Hippocrates and Aristotle all considered mint to be a discouragement to procreation, saying that it discouraged sexual intercourse. However, the Greeks said that mint encouraged sexual behavior and forbade its consumption by soldiers in order to maintain control.

The renowned English naturalist John Ray is credited with the discovery of Peppermint in 1696, when he happened upon Peppermint in a garden when he spotted a sweet yet pungently aromatic plant he had not documented before. So began an era of trial and error, as biologists grappled with the best uses for Peppermint for which the herb is known today.
