For a Burn

Make half a tumbler of strong lime water, let it set a few minutes; then strain the water through a thin muslin to the same quantity of linseed or sweet oil (neat’s or hog’s foot will answer); mix it well, and spread over the burn; wrap over linen cloths. Do not remove the cloth for several days; saturate it frequently with the lime and oil until the inflammation is subdued. Should the odor become offensive, apply cold poultices of the flour of slippery elm; spread over with pulverized charcoal. A plaster of lard and soot is also good for a burn. Heal with any simple salve — a very good one is made by stewing together heart leaves, white lily root, agrimony, a few leaves of the Jamestown weed, and sweet gum. When the strength of the herbs is extracted, strain the water; throw away leaves, etc.; add fresh unsalted butter, and simmer gently until the water has evaporated. Keep this on hand for common sores, in a close-covered box.
