The Geranium is an astringent from the presence of Tannic and Gallic Acids in large quantity; and hence will possess the medicinal properties of these. It is claimed, however, to possess other properties, acting more kindly, and giving tone to mucous membranes. Whilst I believe the remedy has been over-rated, I am confident that experiment will develop some special use.
It may be employed in infusion with good results, especially when a topical action on the stomach and bowels is wanted, or in chronic cases when we desire the action of Gallic Acid. For general use I would suggest a tincture by percolation, using Alcohol of 30°. The Geranin, though not entirely worthless, is a feeble and costly medicine.
