Description of the plant

Mint (Mentha piperita) is a herbaceous perennial plant belonging to the Labiate family. The parts used are the leaves and the flowering tops. It is an erect plant, with flowers arranged in whorls; the stem is hairy and the ovate leaves are very aromatic.

The flower corollas are pink in color. It is a garden plant that blooms in summer and reproduces by suckers. For their herbal use, the flowers and mint leaves are harvested between July and August and left to dry in the open air. 

Habitat of peppermint

Mint is native to Europe and is widespread throughout the world. It grows well in areas with a temperate climate, while it is absent in those with a tropical climate.

Peppermint is a perennial and hardy aromatic herb that grows and develops easily when grown in your garden or in pots, so you can always have its fresh and fragrant leaves at hand. It tolerates sandy soils and full sun exposure, which must be counterbalanced by frequent watering.


Peppermint was born in 1996, the year in which the English botanist John Ray, in the course of his work of classification of the various types of mint, discovered a specimen derived from a natural crossing of different wild varieties (Mentha rotundifolia and Mentha aquatica), which was clearly distinguished from the others by a far more intense perfume.

The cultivation of this plant, which the botanist called peppermint, quickly spread throughout Europe and then also in America and Japan, thanks to its extraordinary aroma. Also, when learning how to distil menthol in the last century, peppermint was found to contain a very high concentration of this substance.

The demand for menthol, which is widely used in the pharmaceutical, confectionery, liqueur industry (manufacturing of toothpastes, mouthwashes, candies, chewing gum) led to a further spread of the cultivation of this plant.
