I have frequently called attention to the use of sulphurous acid in the treatment of exudative throat disorders of all kinds and especially in diphtheria. I have used this remedy for almost thirty years to clear up and remove exudations in the throat and mouth. I long ago ceased trying in the simple cases to determine what the character of the exudate was. I felt confident that this remedy would remove it, and destroy the toxins generated by its development.
It may be used by mixing a quantity of the dilute acid with equal parts of glycerine, and giving this in doses of from ten to thirty drops every hour in a little water. It can be mixed also with syrup, when it becomes very palatable and is not objected to by any child. I have combined it with mucilage of acacia and have added enough sulphur to give from two to five grains at a dose.
The preparation can be used also as a spray with fine results. In an epidemic of diphtheria in 1878 and 79, I depended upon this remedy almost alone to remove the external evidences of the disease, giving other remedies as indicated subsequently.
