[175] A medicinal tincture (H.) is prepared from the root, of which thirty or forty drops may be taken for a dose, with two tablespoonfuls of cold water; but too large a dose will induce sickness. Elecampane is specifically curative of a sharp pain affecting the right elbow joint, and recurring daily; also of a congestive headache coming on through costiveness of the lowest bowel. Moreover, at the present time, when there is so much talk about the inoculative treatment of pulmonary consumption by the cultivated virus of its special microbe, it is highly interesting to know that the helenin of Elecampane is said to be peculiarly destructive to the bacillus of tubercular disease. In classic times the poet Horace told how Fundanius first taught the making of a delicate sauce, by boiling in it the bitter _Inula_ (Elecampane); and how the Roman stomach, when surfeited with an excess of rich viands, pined for turnips, and the appetising _Enulas acidas_ from frugal Campania:-- "Quum rapula plenus Atque acidas mavult inulas." EYEBRIGHT. Found in abundance in summer time on our heaths, and on mountains near the sea, this delicate little plant, the _Euphrasia officinalis_, has been famous from earliest times for restoring and preserving the eyesight. The Greeks named the herb originally from the linnet, which first made use of the leaf for clearing its vision, and which passed on the knowledge to mankind. The Greek word, _euphrosunee_, signifies joy and gladness. The elegant little herb grows from two to six inches high, with deeply-cut leaves, and numerous white or [176] purplish tiny flowers variegated with yellow; being partially a parasite, and preying on the roots of other plants. It belongs to the order of scrofula-curing plants; and, as proved by positive experiment (H.), the Eyebright has been recently found to possess a distinct sphere of curative operation, within which it manifests virtues which are as unvarying as they are truly potential. It acts specifically on the mucous lining of the eyes and nose, and the uppermost throat to the top of the windpipe, causing, when given so largely as to be injurious, a profuse secretion from these parts; and, if given of reduced strength, it cures the same troublesome symptoms when due to catarrh. An attack of cold in the head, with copious running from the eyes and nose, may be aborted straightway by giving a dose of the infusion (made with an ounce of the herb to a pint of boiling water) every two hours; as, likewise, for hay fever. A medicinal tincture (H.) is prepared from the whole plant with spirit of wine, of which an admirably useful lotion may be made together with rose water for simple inflammation of the eyes, with a bloodshot condition of their outer coats. Thirty drops of the tincture should be mixed with a wineglassful of rosewater for making this lotion, which may be used several times in the day.
