A Vapour for the Ear.
Take Hellebore roots both white and black, of each one ounce; each one ounce; Juniper and Bayberries of each 6 drams; Cummin-seed half an ounce; Rue, Wormwood, Camomile flowers, each I handful; Water 3 pints; Vinegar 1 pint and a half, boil to 2 quarts for a Vapour.
This subtile, piercing, and very sharp Vapour, penetrates to the Tympanum it self fuses and deterges the Ear-wax and Filth, and notably strengthens the Tone of the Ear. An eminent Physician (in his place and time) held this a very great Secret against Deafness, and wonderfully commended it to me. Perhaps the first hint of this might be taken from an Oil for the Ear, which Rondeletius makes of white Hellebore roots, Bay and Ash leaves, and Rue boil'd in Wine and Oil.
