Mullein oil is a most valuable destroyer of disease germs. If fresh flowers of the plant be steeped for twenty-one days in olive oil whilst exposed to the sunlight, this makes an admirable bactericide; also by simply instilling a few drops two or three times a day into the ear, all pain therein, or discharges therefrom, and consequent deafness, will be effectually cured, as well as any itching eczema of the external ear and its canal. A conserve of the flowers is employed on the Continent against ringworm. Some of the most brilliant results have been obtained in suppurative inflammation of the inner ear by a single application of Mullein oil. In acute or chronic cases of this otorrhoea, two or three drops of the oil should be made fall into the ear twice or thrice in the day. And the same oil is an admirable remedy for children who "wet the bed" at night. Five drops should be put into a small tumblerful of cold water; and a teaspoonful of the mixture, first stirred, should be taken four times in the day. Flowers of Mullein in olive oil, when kept near the fire for several days in a corked bottle, form a remedy popular in Germany for frost-bites, bruises, and piles. Also a poultice made with the leaves is a good application to these last named troublesome evils. For the cure of piles, sit for five minutes on a chamber vessel containing live coals, with crisp dry Mullein leaves over them, and some finely powdered resin. MUSHROOMS. Without giving descriptive attention to those Mushrooms (_Agarics_, _Boleti_, and others) which are edible, and [363] of which over a hundred may be enumerated, as beyond our purpose when treating of curative Herbal Simples, notice will be bestowed here on two productions of the Mushroom nature--the Puff Ball and the Fly Agaric,--because of their medicinal qualities. It may be first briefly stated that the _Agaricus campestris_, or field Mushroom, is the kind most commonly eaten in England, being highly nitrogenous, and containing much fat. This may be readily distinguished from any harmful fungus by the pink colour of its gills, the solidity of its stem, the fragrant anise-like odour which it possesses, and the separability of its outer skin. Other edible Mushrooms which grow with us, and are even of a better quality than the above, are the _Agaricus augustus_ and the _Agaricus elvensis_, not to mention the _Chanatrelle_, said to be unapproachable for excellence. The Greeks were aware of edible fungi, and knew of injurious sorts which produced a sense of choking, whilst subsequent wasting of the body occurred. Athenaeus quotes an author who said: "You will be choked like those who waste after eating mushrooms." The Romans also esteemed some fungi as of so exquisite a flavour that these would be stolen sooner than silver or gold by anyone entrusted with their delivery:-- "Argentum, atque aurum facile est laenamque togamque. Mittere, boletos mittere difficile est."
