This is Scientific American 60 second Science, I am Sophie Bushwick. Got a minute?
Medicinal tablets are nothing new. Doctors have been dispensing1 pills for thousands of years. And now archaeologists have turned up some of those ancient medicines, which were preserved in a shipwreck2 for close to two millennia4.
The 2nd-century Pozzino wreck3 was discovered in 1974 off the coast of Italy. It’s cargo5 included medical equipment like a cupping vessel6, iron probe, and tin boxes of supplies. in one of those boxes, researchers recovered five gray tablets. Now, they’ve analyzed7 the antique medication. The work is in the Proceedings8 of the National Academy of Sciences.
The pills primarily contained zinc9 compounds, probably the active medicinal ingredients. But researchers also detected starch10, pollen11, charcoal12, fats and linenfibers. Those fibers13 helped the tablets hold their round, loaf-like shape, which may be the key to the medication's use: the Greek word meaning “small round loaves” also inspired the word collyrium, or eye-wash. The pills were probably either dissolved in liquid or ground into a powder and used to treat eye conditions. Who knows, maybe Hippocrates used them on his pupils.
