Herbal Simples Approved for Modern Uses of Cure

by William Thomas Fernie

Two sorts of this herb are cultivated for the market—black and white Peppermint, the first of which furnishes the most, but not the best oil. The former has purple stems, and the latter green. As an antiseptic, and destroyer of disease germs, this oil is signally efficacious, [341] on which important account it is now used for inhalation by consumptive patients as a volatile vapour to reach remote diseased parts of the lung passages, and to heal by destroying the morbid germs which are keeping up mischief therein. Towards proving this preservative power exercised by the oil of Peppermint, pieces of meat, and of fat, wrapped in several layers of gauze medicated with the oil have been kept for seven months sweet, and free from putrescent changes. A simple respirator for inhaling the oil is made from a piece of thin perforated zinc plate adapted to the shape of the mouth and nostrils like a small open funnel, within the narrow end of which is fitted a pledget of cotton wool saturated with twenty drops of the oil, or from twenty to thirty drops of the spirituous essence. This should be renewed each night and morning, whilst the apparatus is to be worn nearly all day. At the same time the oil is agreeable of odour, and is altogether harmless. It may be serviceably admixed with liniments for use to rheumatic parts.

"Peppermint," says Dr. Hughes (Brighton), "should be more largely employed than it is in coughs, especially in a dry cough, however caused, when it seems to act specifically as a cure, just as arnica does for injuries, or aconite for febrile inflammation. It will relieve even the irritative hectic cough of consumptive patients. Eight or ten drops of the essence should be given for this purpose as a dose with a tablespoonful of water. In France continuous inhalations of Peppermint oil combined with creasote and glycerine, have become used most successfully, even when cavities exist in the lungs, with copious bacillary expectoration. The cough, the night sweats, and the heavy phlegm have been arrested, whilst the nutrition and the weight have steadily increased."

[342] A solution of menthol one grain, spirit of wine fifty drops, and oil of cloves ten drops, if painted over the seat of pain, will relieve neuralgia of the face, or sciatica promptly. Unhealthy sores may be cleansed, and their healing promoted, by being dressed with strips of soft rag dipped in sweet oil, to each ounce of which one or two drops of the oil of Peppermint has been added. For diphtheria, Peppermint oil has been of marked use when applied freely twice or three times in the day to the ulcerated parts of the throat. This oil, or the essence, can be used of any strength, in any quantity, without the least harm to the patient. It checks suppuration when applied to a sore or wound, whilst exercising an independent antiseptic influence. "Altogether," says Dr. Braddon, "the oil of Peppermint forms the best, safest, and most agreeable of known antiseptics." Pliny tells that the Greeks and Romans crowned themselves with the Peppermint at their feasts, and adorned their al fresco tables with its sprays. The "chefs" introduced this herb into all their sauces, and scented their wines with its essence. The Roman housewives made a paste of the Peppermint with honey, which they esteemed highly, partaking of it to sweeten their breath, and to conceal their passion for wine at a time when the law punished with death every woman convicted of quaffing the ruby seductive liquor. Seneca perished in a bath scented with woolly mint.

The Spearmint (Mentha viridis) is found growing apparently wild in England, but is probably not an indigenous herb. It occurs in watery places, and on the banks of rivers, such as the Thames, and the Exe. If used externally, its strong decoction will heal chaps and indolent eruptions.

It possesses a warm, aromatic odour and taste, much [343] resembling those of Peppermint, but not so pungent. Its volatile oil, and its essence, made with spirit of wine, contain a similar stimulating principle, but are less intense, and therefore better adapted for children's maladies.

The Spearmint is called "Mackerel Mint," and in Germany "Lady's Mint," with a pun on the word munze. Its name, Spear, or Spire, indicates the spiry form of its floral blossoming. When the leaves of the herb are macerated in milk, this curdles much less quickly than it otherwise would; and therefore the essence is to be commended for use with milk diets by delicate persons, or for young children of feeble digestive powers, though not when feverishness is present. "Spearmint," says John Evelyn, "is friendly to the weak stomach, and powerful against all nervous crudities." "This is the Spearmint that steadies giddiness," writes Alfred Austin, Poet Laureate.

Our cooks employ it with vinegar for making the mint sauce which we eat with roast lamb, because of its condimentary virtues as a spice to the immature meat, whilst the acetic acid of the vinegar serves to help dissolve the crude albuminous fibre.

The oil is less used than that of Peppermint. From two to five drops may be given on sugar; or from half to one teaspoonful of the spirit of Spearmint with two tablespoonfuls of water. Also a distilled water of Spearmint is made, which will relieve hiccough, and flatulence, as well as the giddiness of indigestion. The tincture prepared from the dried herb looks of a bright dark green by day, but of a deep red colour by night. Martial called the Spearmint Rutctatrix mentha. "Nec deest ructatrix mentha."

The Calamint, or Basil Thyme, grows frequently in [344] our waysides and hedges, a labiate plant, with downy stems and leaves, whilst bearing light purple flowers. The whole herb has a sweet, aromatic odour, and makes a pleasant cordial tea. It is named from the Greek kalos, "excellent," because thought useful against serpents; "There is made hereof," said Galen, "An antidote marvellous good for young women that want their courses."

The stem of this pretty slender herb is seldom more than five or six inches high, and its blossoms are so inconspicuous as to be often overlooked. The flowers droop gracefully before expansion. In country places it is often called Mill Mountain, and its infusion is an old remedy for rheumatism. If bruised, and applied externally, it reddens the skin, and will sometimes even blister it. In this way it acts well when judiciously used for lumbago, and rheumatic pains. The Calamint contains a camphoraceous, volatile, stimulating oil, in common with the other mints; this is distilled by water, but its virtues are better extracted by rectified spirit. The lesser Calamint is a variety of the herb possessing almost superior virtues, with a stronger odour resembling that of Pennyroyal. "Apple Mint" is the "Mentha rotundifolia."
