My father and my grandfather would have said "So what else is news?" This story from BBC News:
Moses Mirandu of Zimbabwe learned as a child the healing power of sugar on wounds. Now in UK he is proving this folk remedy's value. Apply a good layer of sugar to a wound - hopefully before it gets infected - and cover it with a bandage. There it will do its job. For many this is salvation when they cannot afford antibiotics.
In America a similar folk remedy is being proven with honey which has been used by veterinarian Maureen McMichael at the University of Illinois veterinary teaching hospital where she has been applying it on animals for years. As with sugar, she comments on its worth where money is in short supply for antibiotics.
The question was raised asking is it safe for diabetics. The answer was yes because sugar is sucrose and sucrose needs to blend with sucrase to convert to glucose. Sucrase is available within the body and the sugar is being used outside the body.
I add that last paragraph because it raises another question in my mind. What we put on our skin is, to a certain extent, absorbed into the body. How far and how well I know not but is it something to consider?
Anyway, as I said at the start, my father would have laughed. His head was full of these old folk remedies which he trusted and used in preference to the fancier and more costly medicines.
