A practical manual offering clear household and civic measures to prevent and treat a contagious pestilence. It is organized around two aims: preserving the healthy through air purification, fumigation, cleanliness, and routines to maintain bodily vigor, and treating the sick with specific regimens including poultices, plasters, medicated fumigations, and dietary care. The text gives step-by-step preparations and recipes for antiseptic and aromatic mixtures, recommends public sanitation alongside private precautions, and emphasizes keeping spirits lively as part of prevention, intended for readers who may lack regular medical attendance.
