A nurse is researching whether an old family remedy using sugar to heal wounds does actually work.
Moses Murandu, from Zimbabwe, grew up watching his father use granulated sugar to treat wounds.
Sugar is thought to draw water away from wounds and prevent bacteria from multiplying.
Early results from a trial on 35 hospital patients in Birmingham are encouraging, but more research is needed.
One of the patients who received sugar treatment on a wound was 62-year-old Alan Bayliss from Birmingham.
He had undergone an above-the knee amputation on his right leg at the Queen Elizabeth Hospital Birmingham and, as part of the surgery, a vein was removed from his left leg leaving a wound which would not heal properly.
Murandu, who is studying for a doctorate at Birmingham University, was contacted and asked to treat the wound with sugar.
Fast recovery
Mr Bayliss said: "It has been revolutionary. The actual wound was very deep - it was almost as big as my finger.
"When Moses first did the dressing he almost used the whole pot of sugar, but two weeks later he only needed to use four or five teaspoons.
The treatment is thought to work because applying sugar to a wound draws the water away, thereby starving the bacteria of what it needs to grow. This prevents the bacteria from multiplying and they die.
