Sore Throat

Everybody has a cure for this trouble, but simple remedies appear to be most effectual. Salt and water is used by many as a gargle, but a little alum and honey dissolved in sage tea is better. An application of cloths wrung out of hot water and applied to the neck, changing as often as they begin to cool, has the most potency for removing inflammation of anything we ever tried. It should be kept up for a number of hours; during the evening is usually the most convenient time for applying this remedy.

Cut slices of salt pork or fat bacon, simmer a few minutes in hot vinegar, and apply to throat as hot as possible. When this is taken off as the throat is relieved, put around a bandage of soft flannel. A gargle of equal parts of borax and alum, dissolved in water, is also excellent. To be used frequently.

Camphorated oil is an excellent lotion for sore throat, sore chest, aching limbs, etc. For a gargle for sore throat, put a pinch of chlorate of potash in a glass of water. Gargle the throat with it
twice a day, or oftener, if necessary
