I'm not sure where I first read about it, but apparently this Leechbook (i.e. Collection of Medical Recipes) or something similar, has recipes that are being reinvestigated today as a cure for MRSA.
The cure in question for an eye infection and came an older version of the Leechbook from the 9th century. It involved minced onion, wine and an extract from a cow's stomach which were mixed together, chilled and kept for nine days. The resulting liquor killed 90% of a MRSA infection and, very interestingly, the cure required the complete concoction rather than a single ingredient.
So, curious to see if I can find something similar in this book, I open a page at random and come upon recipe 365, a cure for 'Gout fester'. For this I need to 'Take a root of radish and put it in honey, three days in summer, and in winter two days; and afterwards pound it in a mortar, and make therof powder; and dry it well in a new pot and anoint the evil with honey and cast above it the powder.' I suppose that might be worth investigating.
Then, on page 309, I find four cures for hiccoughing on page 309, which I am sure will work just as well as anything else. The last one says, 'Take smearwort and stamp it, and mingle it with good wine. And it will destroy the hiccoughing if thou drinkest it.'
Definitely one to try on the Hodmandods - as soon as I find some smearwort.
But there are others too: recipes for lucky days, experiments to find out if a couple are capable of conceiving and then something involving a plant that 'men called Nightshade' which is made into a powder and applied to sores in the mouth. I think I might keep clear of that one - I rather think that one might belong to the category 'kill or cure'.
