  • Field mint or Cornmint (Mentha arvensis L.) with its less sweet but delicate fresh aroma
  • Horsemint or Hungarian peppermint (Mentha longifolia [L.] Hudson, syn. Mentha sylvestris L.) from Balkan countries and South Africa, highest in menthone and therefore very pungent and less sweet.
  • Bergamot mint or Orange mint (Mentha x citrata L.) with its fresh-citrus minty aroma
  • Applemint or Woolley mint (Mentha suaveolens Ehrh.) with its very sweet green aroma
  • Pennyroyal (Mentha pulegium L.) with its drier, earthy-pungent, minty aroma

History of Use of Peppermint

Peppermint is one of the oldest and among the highly beneficial herbs. Evidence shows that the peppermint was used in ancient times in Japan, China, Egypt, and India.

The use of peppermint is found in Chinese and Japanese history and folklore. Traces of peppermint have also been found in Egyptian tombs inside pyramids. Among many ancient texts, peppermint finds mention as a part of culinary and herbal medicine since about 1500 BC. Interestingly, Greek mythology also mentions peppermint in the form of a tale about a nymph “Mentha” or “Minthe” that was transformed into a sweet and aromatic herb by Goddess Persephone.

Extraction of Peppermint Oil

Peppermint oil is extracted by steam distillation of the aerial parts of the plant. The oil is extracted just before the onset of the flowers.

Approximately 70–100 kg of the semi-dried herb yields 1 kg of peppermint oil.

Components Min (%)Max (%)
trans-Sabinene hydrate0.52.0
Menthyl acetate b2.08.0

The main constituents of peppermint oil are menthol followed by menthone. While menthol is known to be anti-inflammatory, menthone is known to be antiseptic and energizing.

The composition of essential oil is affected by many factors as outlined in the article here. In the case of the peppermint oil, the variability in the compositional profile is affected a lot during ontogenesis. The emergence of the flowering stem, appearance of flowers, and development of fruits may result in qualitative and quantitative alterations. For example, at the beginning of shoot development, the herb contains menthone (above 30%) as the main compound, while the ratio of menthol is usually the same or even lower. During shoot growth, the proportion of menthol starts to increase, and at harvest time in a good quality plant material, it reaches more than 40%.

The difference with Spearmint Oil: Spearmint oil is mainly composed of carvone, menthol, limonene, and menthone; while peppermint oil is mainly composed of menthol, menthone, menthylacetate, and eucalyptol.

Adulteration of peppermint oil: Peppermint oil is adulterated with synthetic menthol, menthol from corn-mint oil, and fractions of peppermint terpenes.

Blending with Peppermint Oil

Peppermint oil blends well with many different oils including black pepper, ginger, lavender, lemongrass, rosemary, basil, lemon, cinnamon, juniper berry, eucalyptus, and marjoram.

The blend of peppermint oil and lavender oil is particularly beneficial. The blend is particularly useful for treating skin ailments, soothing the digestive system, curing headaches, or assisting with any other physical challenge.

Mix one drop of peppermint and three drops of lavender in one tablespoon carrier oil. Spread this over the area in need: the abdomen for upset stomach, temples and back of the neck for headache, lower abdomen for cramps or flatulence, muscles or joints in pain, and anywhere on the skin as needed. Peppermint will clear the mind, refresh and uplift your spirits, energize you, and cool down anger.
