Potassii Bichromas.

Botanical name: 

Dose.—For the ordinary uses, gr. ½ to grs. ij. to water ℥iv., a teaspoonful every hour.

Therapeutic Action.—Bichromate of potash exerts a specific influence upon the throat, larynx, and trachea, and to a less extent upon the mucous membrane of the bronchial tubes. It is especially when an exudation is thrown upon the surface, as in diphtheria and pseudo-membranous croup, that it has been found of special importance. In a case of diphtheria where the hoarseness and cough show the involvement of the larynx, and the remedies, Aconite and Phytolacca, do not control the disease, they may be supplemented by this remedy.

It has been employed with marked benefit in pseudo-membranous croup, alternating it with Aconite, and applying Stillingia liniment to the throat.

In any inflammation showing a tendency to a low grade of deposit, bichromate of potash may he thought of as a possible remedy.
