Peppermint can be identified by its fragrant leaves, which grow on short stalks, and by its stems, which have a reddish cast. Its dense spikes of violet flowers bloom in late summer. Peppermint is a hybrid of water mint and spearmint and was first cultivated near London in 1750.
Peppermint grows almost everywhere.
The two main cultivated forms are the black mint, which has violet-colored leaves and stems and a relatively high oil content, and the white mint, which has pure green leaves and a milder taste. Dried peppermint leaf is used in herb teas, either on its own or in mixtures. Peppermint tea is regarded as a stimulant, a cure for flatulence and has antiseptic properties. It is used in treating indigestion, sore throats, colds and toothache, among others. Peppermint, and other herbal teas are being consumed in increasing quantities by the general population purely for enjoyment rather than for their medicinal activity.
