Sunburn
Cover the affected parts with a paste of Arm & Hammer Bicarbonate of Soda and water. Immediately upon application a cooling sensation will be experienced. When the moisture has been absorbed from the paste, the fire of the burn will have disappeared and the danger of blistering is lessened. Application of the paste as soon as possible after one is burned is advisable.
Toothache
“Sodium Bicarbonate in solution (two teaspoonfuls to a pint of water) on plugs of cotton in painful cavities, or applied to the gums… appeases agonizing toothache (Duckworth).”
“Sodium Bicarbonate has a soothing effect on the mucous membrane of the mouth in nearly all inflamed and irritable conditions, and may be freely used. It has also the advantage of overcoming or in some measure of neutralizing acid conditions.”
