Peppermint
For centuries this powerfully aromatic herb has provided relief for indigestion, colds and headaches.
Today, medicinal peppermint is most prized for its ability to soothe the digestive tract, easing indigestion, irritable bowel syndrome and other complaints.
What it is
Peppermint is cultivated worldwide for use as a flavouring agent and herbal medicine. A natural hybrid of spearmint and water mint, peppermint has square stems, oval, pointed, dark green or purple leaves, and lilac coloured flowers.
For medicinal purposes, the leaves and stems of the plant are harvested just before the flowers bloom in summer.
The major active ingredient of peppermint is its volatile oil, which is made up of more than 40 different compounds.
The oil’s therapeutic effect comes mainly from menthol (35-55% of the oil), menthone (15-30%) and menthyl acetate (3-10%). Medicinal peppermint oil is made by steam-distilling the parts of the plan that grow above the ground.
What it does
Particularly effective in treating digestive disorders, peppermint relieves cramps ad relaxes intestinal muscles. It freshens the breath and may clear up nasal congestion as well.
Major benefits
Peppermint oil relaxes the muscles of the digestive tract, helping to relieve intestinal cramping and flatulence. Its antispasmodic effect also makes it useful for alleviating the symptoms of irritable bowel syndrome, a common disorder that is characterised by abdominal pain, alternating bouts of diarrhoea and constipation, and indigestion.
The menthol in peppermint aids digestion becuase it stimulates the flow of natural digestive juices and bile. This action explains why peppermint oil is commonly included in over-the-counter antacids.
Several studies indicat that the menthol in peppermint oil helps to dissolve gallstones as well, providing a possible alternative to surgery. Consult your doctor before trying the oil for this purpose.
You can also put the oil directly on your tongue; it provides a minty antidote to bad breath. Be careful of dosage.
As a tea or as an oil, peppermint serves as a mild anaesthetic to the stomach’s mucous lining, which helps to reduce nausea and motion sickness. The tea may ease symptoms of diverticulosis as well, including flatulence and bloating.
Additional benefits
When it’s rubbed on the skin, peppermint oil relieves pain by stimulating the nerves that perceive cold while muting those that sense pain, making it a welcome remedy for aching muscles.
Finding are contradictory concerning peppermint’s historical use in the treatment of colds and coughs. Some tests suggest that the aromatic plant has no effect. But Commission E, a German health board recognised as an authority on the scientific investigation of herbs, found that peppermint was an effective decongestant that reduced inflammation of the nasal passageways.
In addition, many people with colds reports that inhaling peppermint’s menthol enables them to breathe more easily. Drinking peppermint tea may also offer relief from the bronchial constriction of asthma.

How to take it
Dosage
For the treatment of irritable bowel syndrome, nausea and gallstones: Try enteric-coated capsules containing peppermint oil because they release peppermint oil where it’s most needed – in the small and large intestine rather than in the stomach. Take one or two capsules (containing 0.2 ml of oil per capsule) two or three times a day, between meals.
To freshen the breath: Chew one capsule of peppermint oil. To relieve flatulence ad calm the stomach: Make a tea by steeping 1 or 2 teaspoons of dried peppermint leaves in a cup of very hot water for 5-10 minutes; be sure to cover the cup to keep the volatile oil from escaping.
For congestion: Drink up to four cups of peppermint tea a day. For pain relief: Add a few drops of peppermint oil to 15 ml of neutral oil. Apply to the affected area up to four times daily.
Guidelines for use
Take enteric-coated capsules between meals. If you prefer peppermint tea, drink a cup three or four times a day, after or between meals. Apply peppermint oil or ointments containing menthol no more than three or four times daily.
To take peppermint tincture, put 10-20 drops in a glass of water. Avoid large doses during pregnancy.
Possible side effects
Even when used for prolonged periods, peppermint leaves in the recommended doses generally have no side effects. On rare occasions, enteric-coated peppermint oil capsules can cause skin rash and heartburn.
Topical peppermint oil can produce allergic skin rashes, especially if applying heat as well. If side effects occur, stop using the herb. If using the oil, be cafeful with dosage.
Caution
Because peppermint oil relaxes gastrointestinal muscles, it may aggravate the symptoms of a hiatus hernia.
Peppermint oil should not be applied to the nostrils or chest of infants or children under the age of 5 because it can cause a choking sensation.
Reminder: If you have a medical condition, talk to your doctor before taking supplements.
