Syrup of Moss.
Take Moss (call'd Oak-Lungs) 4 handfuls; Comfry-root 6 ounces; Malaga Raisins ston'd 2 ounces; Liquorice 3 drams; Balsam of Tolu 2 drams; boil in Hydromel simple to 1 pint and a half; and with Sugar sufficient, boil it up, pretty high, into a thick Syrup.
It's (saith the Communicator) famous, and effectual against clangose, convulsive, hooping Coughs; if a spoonful or two be given often, both before and after every fit of Coughing, either in Penny-royal-water, or Pectoral Decoction, for some days.
