On many of the buildings on Iona grows a flowering plant called Ivy-leaved toadflax.
"It’s said that if you crush the plant into a paste and put it on a cut or wound it acts as an anti-inflammatory and stops the bleeding. Some people say it was brought to Scotland in marble from the Mediterranean, but it’s now everywhere on Iona. I’ve also heard some people eat it to help with Type 2 Diabetes."
As told by Chris Merchant, Iona Abbey
