Peppermint is one of the most popularly known flavourings for candies. The plant is extensively cultivated for the strong aromatic oil which it produces, and in this respect it ranks as one of the most important of all plants. This oil is used very extensively in medicines, and for the production of menthol. The cultivation of this species was carried on long ago by the Egyptians. It has a peculiar, penetrating odour, and is pungent and cooling to the taste. In medicines it is used as a stimulant, to allay nausea, and to relieve sudden cramps or pains in the stomach. Peppermint grows from one to three feet high in wet soil, and along brooks, where it may be found from July to September. It is erect and branched, with smooth stems, and increases by underground suckers. It resembles somewhat the Spearmint. The thin, broad oval, sharply pointed dark green leaf is set on purple stained stems, and is regularly toothed. The tiny flowers are arranged in dense whorls, which are closely gathered in a short, thick, round, terminal spike. It ranges from Canada to Florida, Tennessee and Minnesota. Spiraea is from the Greek, meaning, twisting, and alludes to the twisted seedpods in some of the species.
