Burns and Scalds

A piece of cotton wadding, spread with butter or sweet oil, and bound on the burn instantly, will draw out the pain without leaving a scar; also a handful of flour, bound on instantly, will prevent blistering. The object is to entirely exclude the air from the part affected. Some use common baking-soda, dry or wet, often giving instant relief, withdrawing the heat and pain. Another valuable remedy is to beat the yellow of an egg into linseed oil, and apply it with a feather on the injured part frequently. It will afford ready relief and heals with great rapidity. Some recommend the white part of the egg, which is very cooling and soothing, and soon allays the smarting pain. It is the exposure of the part coming in contact with the air that gives the extreme discomfort experienced from ordinary afflictions of this kind, and anything which excludes air and prevents inflammation is the thing to be at once applied.
