Main Chemical Components

L-Menthol: 28 - 40%, L-Menthone: 18 - 25%

The main chemical constituents of Peppermint essential oil are Menthol, Menthone, and 1,8-Cineole, Menthyl acetate and Isovalerate, Pinene, Limonene and other constituents.

The most active of these components are Menthol and Menthone. Menthol is known to be analgesic and is thus beneficial for reducing pain such as headaches, muscle aches, and inflammation.

MENTHOL contains energizing properties that contribute to the overall energizing effect of Peppermint oil. Menthol is known to soothe the smooth muscle that lines the colon.* This relaxant property occurs due to menthol’s ability to keep calcium channels working optimally

METHONE is known to be analgesic as well, but it is also believed to show antiseptic activity. Its invigorating properties lend the oil its energizing effects.


Cultivating & Harvesting

Peppermint has a need for water, and flourishes in cool or temperate regions that are wet such as near streams or in areas with plenty of rainfall, though adequate drainage is also required. In order to produce the ideal balance of oil compounds during the growing phase, the best growing conditions would consist of warm or hot days followed by cool nights. When grown in warm climates, Peppermint can grow in partial shade or full sun. When harvested in the sun, it will be higher in oil content; however, if the growing conditions are too warm, especially at night, less desirable compounds such as highly toxic Menthofuran will form.

When 10% of the Peppermint crop is in the flowering stage, it produces the optimum oil and Menthol yield and quality. When all traces of dew disappear on a dry, sunny day, harvesting can begin. The whole Peppermint plant is cut down with the aid of conventional hay mowers. If the stems become fractured or if the leaves break, there will be lower oil yields and this will prevent the regrowth of the plants. For this reason, it is important to cut the plant neatly. A more economic oil extraction is achieved through lower moisture content, so once the Peppermint is cut, it is left in the field to wilt. Afterward, it is sliced with a forage harvester into a mobile distillation pot, tub, or trailer in which it is transported to the facility for distillation.

Despite the ideal wilting conditions, Peppermint will still lose essential oil from lying in rows of dry leaves or in heaps for any amount of time. If the Peppermint is not checked, the quality and quantity of the oil could be compromised by fermentation - that is, the chemical breakdown of the Peppermint by microorganisms. In order to prevent this, some producers distil the fresh Peppermint as soon as it is cut.
