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.
