Specific for a Cough

Take equal quantities of camomile flowers, elecampane, life-everlasting, mullen, a few races of ginger, and as much fat lightwood splinters as camomile. Boil to a strong tea; strain it, and add enough honey and sugar mixed in equal quantities; boil down to a syrup; add enough good apple vinegar to give a pleasant acid taste. Pills made of fresh tar, brown sugar, and the yolk of an egg,
are good for a cough. Pills of fresh rosin taken from the pine tree are also good.
