entha (also known as mint, from Greek míntha,[2] Linear B mi-ta)[3] is a genus of plants in the family Lamiaceae (mint family).[4] Thespecies are not clearly distinct, and estimates of their number vary from 13 to 18.[5] Hybridization between some of the species occursnaturally. Many other hybrids, as well as numerous cultivars, are known.
The genus has a subcosmopolitan distribution across Europe, Africa, Asia, Australia, and North America.[6]
Mints are aromatic, almost exclusively perennial, rarely annual, herbs. They have wide-spreading underground and overground stolons[7]and erect, square,[8] branched stems. The leaves are arranged in opposite pairs, from oblong to lanceolate, often downy, and with aserrated margin. Leaf colors range from dark green and gray-green to purple, blue, and sometimes pale yellow.[6] 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.
While the species that make up the Mentha genus 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 tall and can spread over an indeterminate area. Due to their tendency to spread unchecked, some mints are considered invasive.[9]
Mint essential oil and menthol are extensively used as flavorings in breath fresheners, drinks, antiseptic mouth rinses, toothpaste, chewing gum,desserts, and candies, such as mint (candy) and mint chocolate. The substances that give the mints their characteristic aromas and flavors are menthol (the main aroma of peppermint and Japanese peppermint) and pulegone (in pennyroyal and Corsican mint). The compound primarily responsible for the aroma and flavor of spearmint is L–carvone.
Mints are used as food plants by the larvae of some Lepidoptera species, including buff ermine moths.
