Porter Plaster for Bruises
This simple, singular, and safe remedy for bruises is nothing more than a gallon of porter simmered in an earthen vessel, till, when cool, it will be of the consistence of a plaster. This preparation was spread on an old glove, and applied round the ancle of a coachman, who was thrown off his box, and miserably bruised. In three days it so effectually performed a cure, that coachee was enabled to remount his box, perfectly relieved from all swelling and pain.

Arnica
For internal bruises nothing answers so well as tincture of arnica. 10 drops in a tablespoonful of water every three hours. It is also one of the best remedies for external bruises of all kinds, relieving the pain caused by blows, falls or other injuries. A lotion made of 1 part of the tincture to 10 of water, apply immediately by well saturating a piece of lint and covering over with oiled silk to prevent evaporation. The sooner this is done after receiving the injury the more likely it is to do good.
