Other experts in the field lauded the discovery as a rare find that offered valuable clues to the actual types of materials used in ancient medicine.
"What we know about ancient medicine is largely contained in manuscripts, often corrupt -- copied and recopied and fragmentary," said Michael Sappol, an historian in the history of medicine division of the U.S. National Library of Medicine. "When the manuscripts refer to plants, it's not always evident what they're referring to. There's a lot we don't know."
Dr. Mark Fromer, an ophthalmologist at Lenox Hill Hospital in New York City, said it makes sense that the medicine that was discovered on the ship was an eye wash to treat dry eye, a common condition even today. "It's easy to make: it's saline, which has a pH [acid balance] close to tears," he explained. "It's fascinating to realize that the problems that faced men and women thousands of years ago haven't changed."
