Origin and History

Peppermint is native to southern Europe and was brought to the USA in the early 19th century. Peppermint is a perennial herb, growing to the height of 30 to 100cm. Mentha piperita belongs to a genus consisting of some 20 varieties and hybrids. Peppermint generally grows best in moist, shaded locations, and expands by underground rhizomes

The major components of the different mints are menthol and pulegone. Cornmint, also referred to as Japanese mint, is cheaper to produce than peppermint and spearmint and is often used as a 'blender' in mint flavours and as an adulterant in peppermint oil.

Method of Extraction

Peppermint oil is steam-distilled from the partially dried herb of Mentha Piperita or Mentha Arvensis. The oil is available in several forms, including:

  • peppermint essential oil - highly concentrated

  • peppermint extracts - which are less concentrated and include hydrosols

Other forms are available, such as enteric-coated capsules which contain a small amount of peppermint oil in a special coating.

Therapeutic properties

Peppermint oil is extensively used in food flavouring, as a fragrance component in toothpaste, mouth washes, soaps, detergents and perfumes.

Peppermint essential oil has cooling, invigorating, clearing, refreshing and antiseptic properties. It is refreshing to the nasal passages when used as an inhalant.

Peppermint essential oil is mildly antiseptic and helps purify the skin. Other reported uses of peppermint essential oil include treatment of irritable bowel syndrome, relief of indigestion, easing nausea, for muscle spasms, pain relief and a sore throat.

Peppermint oil has a high concentration of natural pesticides, mainly pulegone (found mainly in M. arvensis var. piperascens (cornmint, field mint, or Japanese mint), and to a lesser extent (6,530 ppm) in Mentha × piperita subsp. notho and menthone. It is known to repel some pest insects, including mosquitos, and has uses in organic gardening.

Whatever you choose to use peppermint oil for, it is really important to follow professional guidelines and use very small amounts.

Blends Well With

Peppermint essential oil blends well with lavender, chamomile, lemon, rosemary, bergamot and eucalyptus.

Precautions During Use (Contraindications)

Peppermint oil can cause skin irritation, digestive symptoms, and, in some cases, allergic reactions. If a person develops symptoms while using peppermint oil, they should stop using it immediately and speak to a doctor.

Peppermint should not be used on the face, particularly the nose, of infants and small children. Cornmint is considered more toxic than peppermint oil as it has higher pulegone content.

Always refer to IFRA Statements for more information on % inclusion levels for the various varieties of peppermint, when making topical blends containing peppermint oil.

Do not take any oil internally and do not apply undiluted essential oils, absolutes, CO2s or other concentrated essences onto the skin. Seek advice from a qualified aromatherapy or medical practitioner.
