Mint is a genus of plants in the family Lamiaceae(mint family). The exact distinction between species is unclear; it is estimated that 13 to 24 species exist. Hybridization occurs naturally where some species' ranges overlap. Many hybrids and cultivars are known.
The genus has a subcosmopolitan distribution across Europe, Africa, Asia, Australia, and North America. The species that make up the genus Mentha
are widely distributed and can be found in many environments. Most grow best in wet environments and moist soils. Mints will grow 10–120 cm (4–48 inches) tall and can spread over an indeterminate area.
Mints are aromatic, almost exclusively perennial herbs. They have wide-spreading underground and overground stolons and erect, square, branched stems. The leaves are arranged in opposite pairs, from oblong to lanceolate, often downy, and with a serrated margin. Leaf colors range from dark green and gray-green to purple, blue, and sometimes pale yellow. The flowers are white to purple and produced in false whorls called verticillasters. The corolla is two-lipped with four subequal lobes, the upper lobe usually the largest. The fruit is a nutlet, containing one to four seeds. Field Mint is a herbaceous perennial plant growing to 10-60 cm (rarely to 100 cm) tall. The leaves are in opposite pairs, simple, 2-6.5 cm long and 1–2 cm broad, ovate, hairy, and with a coarsely serrated margin. The flowers are pale purple (occasionally white or pink), in distant clusters on the stem, each flower 3-4 mm long. Field Mint is found throughout Eurasia and into tropical Asia, at altitudes of 1200-2000 m.
Corn mint, like many other members of this genus, is often used as a domestic herbal remedy, being valued especially for its essential oil, which has antiseptic properties and a beneficial effect on the digestion. Like other members of the genus, it is best not used by pregnant women because large doses can cause an abortion.
The ancient Greeks rubbed mint on their arms, believing it would make them stronger. Mint was originally used as a medicinal herb to treat stomach ache and chest pains. There are several uses in traditional medicine and preliminary research for possible use in treating irritable bowel syndrome. The whole plant is anaesthetic, antiphlogistic, antispasmodic, antiseptic, aromatic, carminative, diaphoretic, emmenagogue, galactofuge, refrigerant, stimulant, stomachic and vasodilato
