Wash for Foul Ulcers
Permanganate of potassa, 1 dram; pure water, 6 fluid ounces. Clean the sore once or twice a day, with a quart of water, to which a large tablespoonful of the wash has been added, using a soft sponge.
The discoloration of the solution indicates its complete loss of power as a disinfectant.
The bottle must be kept tightly corked, as impurities in the air will, in time, impair its value.
