"Parvenke is an erbe green of colour,
In time of May he bereth blo flour,
His stalkes are so feynt and feye
That nevermore groweth he heye:
On the grounde he rynneth and growe
As doth the erbe that hyth tunhowe;
The lef is thicke, schinende and styf
As is the grene Ivy leef:
Uniche brod, and nerhand rownde;
Men call it the Ivy of the grounde."
In the Organic Materia Medica of Detroit, U.S.A., 1890, it is stated, "Painters use the Ground Ivy (Nepeta glechoma) as a remedy for, and a preventive of lead colic." An infusion is given (the ounce to a pint of boiling water)—one wineglassful for a dose repeatedly. In the relief which it affords as a snuff made from the dried leaves to congestive headache of a passive continued sort, this benefit is most probably due partly to the special titillating aroma of the plant, and partly to the copious defluxion of mucus and tears from the nasal passages, and the eyes.
[287] JOHN'S WORT.
The wild Saint John's Wort (Hypericum peiforatum) is a frequent plant in our woods and hedgebanks, having leaves studded with minute translucent vesicles, which seem to perforate their structure, and which contain a terebinthinate oil of fragrant medicinal virtues.
The name Hypericum is derived from the two Greek words, huper eikon, "over an apparition," because of its supposed power to exorcise evil spirits, or influences; whence it was also formerly called Fuga doemoniorum, "the Devil's Scourge," "the Grace of God," "the Lord God's Wonder Plant." and some other names of a like import, probably too, because found to be of curative use against insanity. Again, it used to be entitled Hexenkraut, and "Witch's Herb," on account of its reputed magical powers. Matthiolus said, Scripsere quidam Hypericum adeo odisse doemones, ut ejus suffitu statim avolent, "Certain writers have said that the St. John's Wort is so detested by evil spirits that they fly off at a whiff of its odour."
Further names of the herb are "Amber," "Hundred Holes," and Sol terrestris, the "Terrestrial Sun," because it was believed that all the spirits of darkness vanish in its presence, as at the rising of the sun.
For children troubled with incontinence of urine at night, and who wet their beds, an infusion, or tea, of the St. John's Wort is an admirable preventive medicine, which will stop this untoward infirmity.
The title St. John's Wort is given, either because the plant blossoms about St. John's day, June 24th, or because the red-coloured sap which it furnishes was thought to resemble and signalise the blood of St. John the Baptist. Ancient writers certainly attributed a host of virtues to this plant, especially for the cure of hypochondriasis, and insanity. The red juice, or "red [288] oil," of Hypericum made effective by hanging for some months in a glass vessel exposed to the sun, is esteemed as one of the most popular and curative applications in Europe for excoriations, wounds, and bruises.
The flowers also when rubbed together between the fingers yield a red juice, so that the plant has obtained the title of Sanguis hominis, human blood. Furthermore, this herb is Medicamentum in mansâ intus sumptum, "to be chewed for its curative effects."
And for making a medicinal infusion, an ounce of the herb should be used to a pint of boiling water. This may be given beneficially for chronic catarrhs of the lungs, the bowels, or the urinary passages, Dr. Tuthill Massy considered the St. John's Wort, by virtue of its healing properties for injuries of the spinal cord, and its dependencies, the vulnerary "arnica" of the organic nervous system. On the doctrine of signatures, because of its perforated leaves, and because of the blood-red juice contained in the capsules which it bears, this plant was formerly deemed a most excellent specific for healing wounds, and for stopping a flow of blood:—
