| Peppermint |
Peppermint (Mentha piperita) is an aromatic perennial plant that grows to a height of about 3 ft (1 m). It has light purple flowers and green leaves with serrated edges. Peppermint belongs to the Lamiaceae family and grows throughout North America, Asia, and Europe. There are more than 25 species of true mint grown throughout the world.
The plant is harvested when the oil content is highest. When ready for harvest, it is always collected in the morning, before noon sun reduces the leaf essential oil content.
This generally takes place shortly before the plant blooms, which occurs in the summer (July through August) or during dry, sunny weather. The United States is responsible for producing 75% of the world’s supply of peppermint.

History
Peppermint is a natural hybrid of water mint (Mentha aquatica) and spearmint (Mentha spicata) and was first cultivated in England in the late seventeenth century. The herb has been used as a remedy for indigestion since Ancient Egyptian times. In fact, dried peppermint leaves were found in Egyptian pyramids dating back to 1000 B.C.
The ancient Greeks and Romans valued it as a stomach soother. During the eighteenth century, peppermint became popular in Western Europe as a folk remedy for nausea, vomiting, morning sickness, respiratory infections, and menstrual disorders.
Peppermint was first listed in the London Pharmacopoeia in 1721. In modern times it appears in the British Herbal Pharmacopoeia as a remedy for intestinal colic, gas, colds, morning sickness, and menstruation pain.
Properties
Peppermint is a cooling, relaxing herb that contains properties that help ease inflamed tissues, calm muscle spasms or cramps, and inhibit bacteria and microorganisms. It also has pain-relieving and infection-preventing qualities.
The medicinal parts of peppermint are derived from the whole plant, and include a volatile oil, flavonoids, phenolic acids, and triterpenes. The plant is primarily cultivated for its oil, which is extracted from the leaves of the flowering plant.
The essential oil contains the principal active ingredients of the plant: menthol, menthone, and menthyl acetate. Menthyl acetate is responsible for peppermint’s minty aroma and flavor. Menthol, peppermint’s main active ingredient, is found in the leaves and flowering tops of the plant. It provides the cool sensation of the herb.
The menthol content of peppermint oil determines the quality of its essential oil. This varies depending upon climate, habitat, and where the peppermint is grown.
For instance, American peppermint oil contains 50–78% menthol, while English peppermint oil has a menthol content of 60–70%. Japanese peppermint oil contains 85% menthol. Peppermint and its oils help with intestinal function.
Peppermint also contains vitamin A and C, magnesium, potassium, inositol, niacin, copper, iodine, silicon, iron, and sulfur.
General use
 |
| Peppermint Essential Oil |
Peppermint is one of the most popular flavoring agents. Many products contain peppermint, including chewing gum, mints and candies, ice cream and other sweets, tobacco, toothpaste, mouthwash, cough drops, teas, alcoholic liqueurs, and digestive aids.
It is also used to scent soaps, perfumes, detergents, lipsticks and other cosmetics, and is an ingredient in many over-the-counter medications. Therapeutically, peppermint is used to treat many ailments of the skin, circulatory system, respiratory system, digestive system, immune system, and nervous system.
Peppermint and headaches
Peppermint’s pain-relieving effects on headaches have been known for many years. The first documented report to link peppermint and headache relief was published in 1879.
A more recent study took place in Germany in 1996. In this double-blind study, researchers found that an ethanol solution containing 10% peppermint oil was as effective in relieving headache pain as 1,000 mg of acetaminophen.
In another study, 32 people with headaches massaged peppermint oil on their temples. The results showed that the peppermint oil significantly relieved their pain.
When applied to the skin, peppermint reduces sensitivity and relieves pain. Rubbed on the temples, across the forehead, and behind the neck, peppermint oil helps to ease digestive-related headaches and migraines by generating a cooling effect on the skin and relaxing cranial muscles.
Peppermint as a digestive aid
Peppermint is employed in the treatment of various digestive ailments, such as irritable bowel syndrome, Crohn’s disease, diverticulitis, liver and gallbladder complaints, loss of appetite, spastic colon, diarrhea, gas, bloating, colic, cramps, and heartburn.
The infused herb tea of peppermint or a few drops of its essential oil stimulate the flow of digestive juices and the production of bile, a substance that helps to digest fats. This eases indigestion, relieves gas, reduces colon spasms, and eases motion sickness and nausea.
When peppermint is taken after a meal, its effects will reduce gas and help the digestion of food by reducing the amount of time the food is in the stomach. This is one reason after-dinner mints are so popular.
The compounds of the essential oil have antispasmodic properties that reduce spasms of the colon and intestinal tract and relax the stomach muscles. Peppermint has a soothing effect on the lining and muscles of the colon, which helps to relieve diarrhea and spastic colon.
Menthol acts to stimulate the stomach lining. Its cooling properties soothe the stomach and ease stomach pain. Peppermint oil is popular in the treatment of motion and sea sickness and nausea associated with pregnancy. It acts as an anesthetic to the stomach wall and eases vomiting and nausea.
An account on the effects of peppermint on nausea appeared in the September 1997 issue of the Journal of Advanced Nursing, in which gynecological patients were given peppermint oil to counter post-operative nausea. The patients reported less nausea and required fewer drugs to treat the nausea.
A German health commission, German Commission E, has endorsed peppermint tea as a treatment for indigestion. Clinical trials in Denmark and Britain in the 1990s confirmed peppermint’s actions as a therapeutic treatment for irritable bowel syndrome.
In 1996, a German study was performed to research the therapeutic benefits of peppermint essential oil on irritable bowel syndrome. Subjects with irritable bowel syndrome were given enteric-coated capsules containing peppermint and caraway oils. Results showed that the pain symptoms, which ranged from moderate to severe, improved in 89.5% of the group.
Peppermint and respiratory ailments
Peppermint is an expectorant and decongestant. It is used to help treat many respiratory ailments including asthma, bronchitis, sinusitis, and coughs.
Peppermint is an element of many cough preparations, not only for its pleasant flavor, but also because it contains compounds that help ease coughs. Constituents of peppermint increase the production of saliva, causing frequent swallowing and suppressing the cough reflex.
German Commission E has officially recognized peppermint’s ability to reduce inflammation of nasal passageways. When menthol vapors are inhaled, nasal passageways are opened to provide temporary relief of nasal and sinus congestion.
Peppermint essential oil is an ingredient in many commercial chest and cold rubs. These are popularly rubbed onto the chest to ease congestion. A tea made from the leaves can stimulate the immune system and relieve the congestion of colds, flus, and upper respiratory infections.
Other conditions
Peppermint is an effective relaxant and can be helpful in treating nervous insomnia, stress, anxiety, and restlessness.
Many over-the-counter balms and liniments contain peppermint essential oil. These are applied externally to relieve muscle pain, arthritis, itching, and fungal infections.
Peppermint induces sweating and can help bring down fevers. It is said that it contains antioxidants that help prevent cancer and heart disease. The essential oil is a powerful antiseptic and is useful in treating bad breath and sore throats. It is also beneficial in preventing tooth decay and gum disease.
A plant with potent antiviral properties, peppermint can help fight viruses that cause ailments such as influenza, herpes, yeast infections, and mumps. Peppermint is also used as an earache remedy, to dissolve gallstones, to ease muscle tightness, and to ease menstrual cramps.
A 2002 report announced that peppermint also helped participants in a study run faster do more pushups and show greater grip strength than those who were not exposed to peppermint scent.
Although researchers concluded the effect may have been psychological, a result of peppermintÃs effect on mood and increased motivation, it still resulted in measurable performance improvement.
