The discovery suggests that ancient books could hold overlooked medical records, bridging gaps between written history and scientific understanding of diseases from centuries ago. The find raises questions about how often such traces might appear in other preserved documents, offering a rare glimpse into the health crises of the past. Experts are now examining whether similar biological remnants could be found in other historical texts.
