E. R. Billings, Tobacco; Its History, Varieties…
“ In the Thirty Years' War in Germany, the smoking and chewing of tobacco proved the salvation of many thousands of men, who by its aid guarded themselves against the deadly effects of deficient food and of bad meats and drinks. Nothing is so good, nothing so serviceable to human life, as the smoking of tobacco—which may well be called a kingly plant, seeing that the monarchs of the earth are not ashamed to use it. While tobacco cultivates sociality, and is of great avail in severe hunger and thirst, it strengthens the body and checks fluxions, and colds, and slimy humors. ”
