Part Used: The Herb.The dried leaves and flowering tops, collected before the flowers are fully developed. Spearmint is cultivated like peppermint for the production of oil, but on a less extensive scale.*
Habitat and range.:Perennial herb native to Central Europe now naturalized throughout the U.S. and Canada. Found growing on roadsides and in waste places, usually in damp soils and sunny positions. Like peppermint, the spearmint has also been naturalized from Europe and may be found in moist fields and waste places from Nova Scotia to Utah and south to Florida. It is also cultivated to some extent for the distillation of the oil, especially in Michigan and Indiana, and for domestic use it is a familiar garden plant.

Description.—Spearmint in its general characteristics resembles peppermint, but it is rather more vigorous in its growth, the lance-shaped leaves are generally stemless, and the flower spikes are narrow and pointed rather than thick and blunt.

...

From creeping root-stocks, erect, square stems rise to a height of about 2 feet, bearing very short-stalked, acute-pointed, lance-shaped, wrinkled, bright green leaves, with finely toothed edges and smooth surfaces, the ribs very prominent beneath. The small flowers are densely arranged in whorls or rings in the axils of the upper leaves, forming cylindrical, slender, tapering spikes, pinkish or lilac in colour. The little labiate flowers are followed by very few, roundish, minute brownseeds. The taste and odour of the plant are very characteristic.

There are several forms of Garden Mint, the true variety being of bold, upright growth, with fairly large and broad leaves, pointed and sharply serrated (or toothed) at the edges and of a rich, bright, green colour. Another variety, sometimes sold as Spearmint (M. cardiaca), is much smaller and less erect in growth, with darker leaves, the whorls of flowers distant and leafy, but possessing the same odour and flavour, and another has comparatively large, broad or rounded leaves. Yet another has soft hairs, but this, though distinct from what is known as Horse Mint, is inferior to the true Spearmint.

A form with its leaves slightly crisped is common in gardens under the name of M. crispa.

Cultivation: A moist situation is preferable, but mint will succeed in almost anysoil when once started into growth, though in dry, sandy soils it is sometimes difficult to grow, and should be planted in the coolest and dampest situations. Leaf mould, road scrapings, burnt ash and similar materials should, on the other hand, be used freely for lightening heavy, tenacious soils. It does best in a partially shaded position: if in a sheltered spot, it will start earlier in the spring than if exposed. Where a long or regular supply is required, it is a good plan to have at least one bed in a sunny and sheltered, and another in a shady position, where gatherings may be made both early and late.

As the plant is a perennial, spreading by means of its underground, creeping stems propagation may be easily effected by lifting the roots in February or March, dividing them - every piece showing a joint will grow - and planting again in shallow trenches, covering with 2 inches of soil. Six inches apart in the rows and 8 inches between the rows are the right distances to allow. Cuttings in summer or offsets in spring may also be utilized for increasing a stock. Cuttings may be taken at almost any time during the summer, always choosing the young shoots, these being struck on a shady border of light soil and kept moist, or a better plan, if possible, is to insert them in a frame, keeping them close and moist till rooted. Cuttings or young shoots will also strike freely in good-sized boxes in a heated greenhouse, in the early spring, and after the tops have been taken off two or three times for use, the plants may be hardened off and planted outside.

The beds are much benefited by an annual top-dressing of rich soil, applied towards the close of autumn, when all remaining stalks should be cut down to the ground. A liberal top-dressing of short, decayed manure, such as that from an old hot-bed or mushroom bed, annually, either in the spring, when it commences to grow, or better still, perhaps, after the first or second cutting, will ensure luxuriant growth. Frequent cuttings of shoots constitute a great drain on the plants, and if not properly nourished they will fail, more or less. To have really good mint, the plantation should be re-made about every three years, or failing that, it is essential that a good top-dressing of rich soil be added.

A good stock should be kept up, so that plenty may be available for forcing. Cultivators having a greenhouse can easily force mint into an earlier development of new growth than would be in the open garden. Forcing is very easy, the only preparation being the insertion of a quantity of good roots in a box of light soil, which should be placed in a temperature of about 60 degrees and watered freely as soon as growth starts. Cuttings may be made in two or three weeks. Forcing will generally be necessary from November to May - a succession being kept up by the introduction, at intervals of about three weeks, of an additional supply of roots, as forced roots soon decay. Often mint is so grown both upon and under the benches in greenhouses, and the demand for the young, tender stems and leaves during the winter is sufficient to make the plants pay well.

Constituents: The chief constituent of Spearmint oil is Carvone. There are also present Phellandrine, Limonene and dihydrocarveol acetate. Esters of acetic, butyric and caproic or caprylic acids are also present. (An Ester is a combination of an alcohol with an acid, the combination being associated with the elimination of water. The esters are highly important and in many cases dominant constituents of numerous essential oils, which owe their perfume largely, or in some cases entirely, to the esters contained. Many of the esters are used as flavouring or perfumery agents, and many are among the most important constituents of volatile salts.)

There are several different essential oils known under the name of Spearmint oil, the botanical origin of the plant used for distillation differing with the country in which the plant is grown. In the United States and in this country several varieties of M. viridis are distilled. In Russia the plant distilled is M. verticellata, and in Germany either M. longifolia, or more generally M. aquatica var. crispa - a plant cultivated in Northern Germany, the oil (called there Krausemünzöl) being imported into this country as German Spearmint oil. It appears to be identical with that from M. viridis. Oil of Spearmint is little distilled in England, either German oil or American oil distilled from M. viridis being imported.

Medicinal Action and Uses: Spearmint is chiefly used for culinary purposes. The properties of Spearmint oil resemble those of Peppermint, being stimulant, carminative and antispasmodic, but its effects are less powerful, and it is less used than Peppermint, though it is better adapted for children’s maladies. From 2 to 5 drops may be given on sugar, or from 1/2 to 1 teaspoonful of spirit of Spearmint, with 2 tablespoonsful of water. Spearmint oil is added to many compounds on account of its carminative properties, and because its taste is pleasanter and less strong than Peppermint. A distilled water of Spearmint will relieve hiccough and flatulence as well as the giddiness of indigestion. For infantile trouble generally, the sweetened infusion is an excellent remedy, and is also a pleasant beverage in fevers, inflammatory diseases, etc. Make the infusion by pouring a pint of boiling water on an ounce of the dried herb; the strained-off liquid is taken in doses of a wineglassful or less. It is considered a specific in allaying nausea and vomiting and will relieve the pain of colic. A homoeopathic tincture prepared from the fresh plant in flower has been found serviceable in strangury, gravel, and as a local application in painful haemorrhoids. Its principal employment is for its febrifuge and diuretic virtues.

Spearmint is edible and Medicinal, the leaves and flowers are edible raw or cooked. A strong flavor, they are used in salads or added to cooked foods. A medicinal herb tea made from the fresh or dried leaves has a very pleasant and refreshing taste, leaving the mouth and digestive system feeling clean. Also great for mint jelly, an old favorite

The proven medicinal constituents in spearmint are 1,8-cineole, acetic-acid, acetophenone, alpha-pinene, alpha-terpineol, apigenin, arginine, benzaldehyde, benzyl-alcohol, beta-carotene, beta-sitosterol, borneol, calcium, carvacrol, carvone, caryophyllene, diosmin, ethanol, eugenol, farnesol, geraniol, hesperidin, limonene, luteolin, menthol, methionine, niacin, oleanolic-acid, perillyl-alcohol, pulegone, rosmarinic-acid, terpinen-4-ol, thiamin, thymol, tryptophan, ursolic-acid, and many vitamins and minerals. An essential oil from the leaves and flowers is used as a flavoring in candy, gum, ice cream, drinks and commercially prepared hygen products (toothpaste, mouthwash, etc). Spearmint has been used as an alternative medicine for centuries on many different continents. It is antiemetic, antiseptic, antispasmodic, carminative, diuretic, restorative, stimulant, stomachic and tonic. The medicinal herb tea made from the leaves is used in the treatment of fevers, bronchitis, chills, cramps, chronic gastritis, common cold, headaches, indigestion, morning sickness, motion sickness, nasal congestion, nausea, halitosis, painful menstruation, and various minor ailments. Externally the stems are crushed and used as a medicinal poultice on bruises. The essential oil in the leaves, is a great rub for stiffness, muscle soreness and rheumatism, the oil also a powerful antiseptic and should not be taken in large doses. Futher research is proving the plant to be of use in many diseases.

Folklore
Both the essential oil and the stems are used in folk remedies for cancer. A poultice prepared from the leaves is said to remedy tumours. The plant repels insects, rats, mice and was formerly used as for strewing (thrown about).

Preparations and Dosages and Recipes: Fluid extract, 1/4 to 1 drachm. Water, B.P. and U.S.P., 4 drachms. Spirit, U.S.P., 30 drops.

When eaten with lamb, very finely chopped in sweetened vinegar, in the form of mint sauce, mint greatly aids the digestion, as it makes the crude, albuminous fibres of the immature meat more digestible. The volatile oil stimulates the digestive system and prevents septic changes within the intestines.

The fresh sprigs of mint are used to flavour green peas and also new potatoes, being boiled with them, and the powdered, dried leaves are used with pea soup and also in seasonings. On the Continent, especially in Germany, the powdered, dried mint is often used at table for dusting upon pea and bean purées, as well as on gravies.

A grating of mint is introduced sometimes into a potato salad, or into a fowl stuffing, and in Wales it is not unusual to boil mint with cabbage.

Mint Jelly can be used instead of mint sauce, in the same manner as red currant jelly. It may be made by steeping mint leaves in apple jelly, or in one of the various kinds of commercial gelatine. The jelly should be a delicate shade of green. A handful of leaves should colour and flavour about half a pint of jelly. Strain the liquid through a jelly bag to remove all particles of mint before allowing to set.

Mint Vinegar is made as follows: Fill a jar or bottle with young mint leaves picked from the stalks. Cover with cold vinegar and cork or cover the bottle. Infuse for 14 days, then strain off the vinegar.

This vinegar is sometimes employed in making Mint Jelly, as follows:

Take 1 pint of water, 1 1/4 OZ. gelatine, the white and shell of an egg, 1/2 gill of Mint Vinegar, 1 dessertspoonful of Tarragon Vinegar, a bunch of herbs, 1 onion, 1 carrot, a stick of celery, 10 peppercorns, salt, 1 lemon. Peel the lemon very thinly, slightly whip the white of egg, wash and crush the shell. Put all the ingredients into a pan, strain in the juice of the lemon and whisk over the fire until just on boiling point. Boil up, then draw the pan to the side of the fire and simmer very gently for 20 minutes. Strain through a jelly bag until clear. Put into a mould to set. If liked, finely chopped mint may be added to the jelly after straining it, or more mint can be used and no Tarragon Vinegar.

To make Mint Punch: Pick a quart of fresh mint leaves, then wash and dry them by shaking them in a clean kitchen towel. Put them into a large jug and mash them with a wooden spoon till soft, when cover with freshly boiled water and infuse for ten minutes. Strain, cool, then set on ice till required. Add two cups of chilled grape juice and strained lemon juice to taste. Sweeten with castor sugar, stir till sugar is dissolved and then add a quart of ginger ale. Fill each tumbler to one-third with cracked ice and fill up with the punch.

The Garden Mint is also the basis of Mint Julep and Mint-water, the cordial distilled from the plant.

Mint Cake is a cake made of flour and dripping or lard, flavoured with sugar and chopped fresh mint and rolled out thin.

Easy Mint Jelly: Steep a handful of mint leaves in one of the various kinds of sweetened gelatin. The jelly should be a delicate shade of green and make about a pint of jelly. Some like to strain the liquid through a cheese cloth to remove all particles of mint before allowing to set, I kinda like the little green specks.
