Scalds, Alum for Slight

"Put a teaspoonful of alum in a pint of water, and bathe the parts frequently. Keep the parts well wet with this solution which extracts the heat in a remarkable manner and soothes the patient into a calm and refreshing sleep." This remedy is most always at hand and will relieve if the case is not too severe.
