A Cataplasm with Cummin.
Take Onions roasted under the Embers 1 ounce and a half; Saffron clip'd small with Scissars 15 grains; Oil of Amber 12 drops; powder'd Cummin Seed, Ointment of Marsh Mallows, each 3 drams, mix.
Its very available in Pains of the Ears; ought to be put on hot as can be endur'd, and renew'd every four Hours, as long as the Pain continueth.
Some are mightily against putting Opium into the Ears, for fear it relax the Tone, and cause Deafness: For my part, I have had no great Experience of it myself, but don't think its likely to do so.
