Dissolve a few scruples of sulphuret of potash in half a pint, or a pint of water, and administer it a little at a time, as the patient can bear it; having first given the white of an egg.
Another remedy is to mix two tea-spoonfuls of made mustard with sufficient warm water to thin it, so as to make it easy to swallow. It acts as an emetic, and is good for any poison.
If corrosive sublimate (one of the worst poisons) has been swallowed, immediately drink a large quantity of olive oil, even the whole contents of a flask; or more, indeed, if that is not found sufficient. This remedy, if taken in time, is always efficacious. If it cannot be immediately obtained, try white of egg.
A cup of the strongest possible coffee has been known to keep the patient awake, and effect a positive cure when all other means have failed. After the fatal sleep has been thus prevented, and the patient is thoroughly roused and excited, let an emetic be administered.
Take a quarter of an ounce of senna and manna (obtained ready mixed from the druggists') and pour on it not quite a pint of boiling water. Cover it; set it by the fire; and let it infuse for an hour. If the vessel in which you prepare it has a spout, stop up the spout with a roll or wad of soft paper. This should always be done in making herb teas, or other decoctions; as a portion of the strength evaporates at the spout. When the infusion of senna and manna has thus stood an hour at the fire, strain it into a skillet or sauce-pan (one lined with porcelain will be best) and stir in a large wine-glass or a small teacup-full of West India molasses. Add about half a pound or more of the best prunes; putting in sufficient prunes to absorb all the liquid during the process of stewing. Then cover the vessel closely, and let it stew (stirring it up occasionally) for an hour; or till you find the stones of the prunes are all loose. If stewed too long, the prunes will taste weak and insipid. When done, put it into a dish to cool; and pick out all the stones. If properly prepared there will be no perceptible taste of the senna and manna. It may oe given to children at their lunch or supper.
Take a large bunch of the herb hoarhound, as green and fresh as you can get it. Having picked it clean, and washed it, cut it up (leaves and stalks) with scissors. Scald, twice, a china tea-pot or a covered pitcher; then empty it of the hot water. Put in the hoarhound, pressing it down with your hands. The pot should be about two-thirds full of the herb. Then fill it up with boiling water; cover it closely, and wedge a small roll of paper tightly into the mouth of the spout, to prevent any of the strength escaping with the steam. Set it close to the fire to infuse, and keep it there till it begins to boil. Then immediately take it away, and strain it into another vessel. Mix with the liquid sufficient powdered loaf-sugar to make it a very thick paste. When the sugar is in, set it over the fire, and give it a boil, stirring and skimming it well. Take a shallow, square tin pan, grease it slightly with sweet oil, and put into it the candy, as soon as it is well boiled; smoothing the surface with a wet knife-blade. Sift over it some powdered sugar. Set it away to cool; and when nearly congealed, score it in squares. It is a well-known remedy for coughs and hoarseness.
If you find it too thin, you may stir in, while boiling, a spoonful of flour, of arrow-root, or of finely-powdered starch.
Another way of making this candy is, to boil the hoarhound in barely as much water as will cover it, and till all the juice is extracted. Then squeeze it through a cloth, and give the strained liquid another boil, stirring in, gradually, sugar enough to make it very thick and stiff. Afterwards sift sugar over a shallow tin pan, fill it with the paste, and leave it to congeal; scoring it in squares before it is quite hard.
Any herb-candy may be made as above.
