A Cataplasm with Elder.
Take green Leaves (or, in the Winter time, inner Bark) of Elder 4 ounces; cut and boil them in Milk 'till soft; strain away the Milk, and to the Mash add soft Soap 1 ounce; spread it upon a double Cloth; strew it with Ceruse and apply it warm.
It wonderfully qualifies St. Anthony's Fire.
