Note - The coating of the tongue does not always wholly influence the choice of a remedy in all affections of the tissues. If any one, suffering from a chronic catarrh of the stomach, take also another (acute) disease, the coating of the tongue will not always have that peculiar appearance which will indicate the remedy suited to the acute disease. If any disease, particularly of a chronic nature, shows itself without decisive symptoms, then the coating of the tongue will, in most cases, guide in the choice of an appropriate remedy. (Schussler).
