Oil Of Cinnamon As An Antiseptic

Oil of cinnamon in a 9-per-cent emulsion, when used upon the hands, completely sterilizes them. A 7-to 8-per-cent emulsion is equal to a 1-per-cent solution of corrosive sublimate and is certainly far more agreeable to use. Oil of thyme in an 11-per-cent solution is equal to a 7-percent solution of cinnamon oil.

Green Coloring For Antiseptic Solutions

The safest coloring substance for use in a preparation intended either for internal administration or for application to the skin is the coloring matter of leaves, chlorophyll. A tincture of spinach or of grass made by macerating 2 ounces of the freshly cut leaves in a pint of alcohol for five days will be found to give good results. If the pure coloring substance is wanted the solvent should be evaporated off.
