Granny's advice about taking a hot drink to fight the effects of a cold was correct all along, say experts.
Researchers at Cardiff University's Common Cold Centre found a hot mug of fruit cordial could help ease the coughs and splutters of a cold or flu. They believe the research, published in the latest edition of clinical journal Rhinology, is the first of its kind.
The effect of an apple and blackcurrant drink served at room temperature or hot was monitored on 30 volunteers. Centre director Professor Ron Eccles urged anyone suffering from a cold or flu to have a hot drink to help reduce their symptoms.
"It is surprising that this is the first scientific research on the benefit of a hot drink for treating cold and flu symptoms," he said. "With temperatures falling and Christmas just round the corner, cold viruses love this time of year. Having a bottle of fruit cordial in the cupboard and making a hot drink could help fight off the symptoms of festive cold and flu."
