Peppermint (Mentha × piperita, also known as Mentha balsamea Wild.) is a hybrid mint, a cross between watermint and spearmint. Indigenous to Europe and the Middle East, the plant is now widely spread and cultivated in many regions of the world. It is occasionally found in the wild with its parent species.Although the genus Mentha comprises more than 25 species, the most common one used is peppermint. While Western peppermint is derived from Mentha piperita, Chinese peppermint, or “Bohe” is derived from the fresh leaves of Mentha haplocalyx. Mentha piperita and Mentha haplocalyx are both recognized as plant sources of menthol and menthone and are among the oldest herbs used for both culinary and medicinal products.
Spearmint, also known as garden mint, common mint, lamb mint and mackerel mint, is a species of mint, Mentha spicata, native to Europe and southern temperate Asia, extending from Ireland in the west to southern China in the east. It is naturalized in many other temperate parts of the world, including northern and southern Africa, North America and South America. It is used as a flavouring in food and herbal teas. The aromatic oil, called oil of spearmint, is also used as a flavouring and sometimes as a scent.
