Digitalis, exhibited in small and gradually augmented doses, acts as a specific excitant to the kidneys, promoting the secretion of urine; on account of this property it has been much used by some practitioners in dropsical effusions. Pereira says: "Of all remedies for dropsy, none have gained more, and few so much celebrity as fox-glove."
