"Bonn, July 19, 1852. "This light and pleasant Farina is one of the most excellent, nourishing, and restorative remedies, and supersedes, in many cases, all kinds of medicines. It is particularly useful in confined habit of body, as also diarrhoea, bowel complaints, affections of the kidneys and bladder, such as stone or gravel; inflammatory irritation and cramp of the urethra, cramp of the kidneys and bladder, strictures, and hemorrhoids. This really invaluable remedy is employed with the most satisfactory result, not only in bronchial and pulmonary complaints, where irritation and pain are to be removed, but also in pulmonary and bronchial consumption, in which it counteracts effectually the troublesome cough; and I am enabled with perfect truth to express the conviction that Du Barry's Revalenta Arabica is adapted to the cure of incipient hectic complaints and consumption.
