Scientists in Harrison’s lab followed the recipe precisely and it was a total success. The ancient drug had the power even to breach the sticky coating and the dense clustering of mature colonies of bacteria, which are notorious resistant to antibacterial treatments. Onion, garlic, part of a cow’s stomach and plants in the garlic family are contained and a little quantity of English wine – taken from a historic vineyard near Glastonbury must be added.. There are many similar medieval books with treatments for what appear to be bacterial infections and researchers will try to test them now, when antibiotic resistance is a growing problem around the world. The team’s findings will be presented at the Annual Conference of the Society for General Microbiology, in Birmingham, this week.
