Peppermint (Mentha x piperita) is an herb that naturally grows in Europe and North America but is now cultivated worldwide. Aside from the minty and fresh feeling it leaves our mouth, peppermint essential oil is also famous for its aromatherapeutic effects. It is the most widely used oil commercially and medicinally.

It is believed that peppermint has originated from Northern Africa and the Mediterranean. Although some claims that it was first cultivated in England in the 18th century, ancient Egyptian texts that date back to 1550 BC have already documented the use of mint for stomach pains. It had been so popular and valued then that it was currency for a period. 

Peppermint vs Spearmint

For people who are not keen on gardening or using this herb, peppermint and spearmint may seem indistinguishable. Both herbs belong to the mint family (Lamiaceae) but they are two different species. Peppermint is a hybrid between the water mint and the spearmint, which means it contains a higher amount of menthol compared to spearmint. While spearmint essential oil has a subtle and sweet odor, peppermints have a strong, peppery scent that sets it apart from the rest of the mint family.

Peppermint Essential Oil Components

Peppermint is famous because of its cooling effect and minty aroma. This is because of the presence of menthol and menthyl acetate which are extracted from the leaves and flowers of the plant. Pure peppermint oil is almost colorless. It is mainly composed of menthol (36.02%), menthone (24.56%), menthyl acetate (8.95%), and menthofuran (6.88%) with minor components such as 1,8-cineole, limonene, beta-pinene, and beta-caryophyllene. The quality of the peppermint oil depends on its menthol content, which can be affected by the place it was cultivated and the climate. 

Ancient uses of peppermint oil

During the Greek and Roman period, peppermint oil was already used to add flavor to food and wine. There were also dried peppermint leaves found in several pyramids. It was said that Ancient Egyptians used these to relieve stomach pains and help with digestive problems. The Greek philosopher Aristotle stated that peppermint works as an aphrodisiac. Soldiers were even forbidden to use or consume it so they don’t get distracted by their feelings or emotions.
