It's something that its advocates have known for ages - the herbal remedy echinacea is the best thing around for preventing the common cold. And now, after researching all the evidence, scientists agree with them.
Echinacea can help reduce your chances of getting a cold by more than half if you take it regularly - and, even if you do catch a cold, the remedy can help clear it up more quickly.
Researchers from the University of Connecticut School of Pharmacy reviewed 14 studies into the remedy, and concluded that it reduces your risk of catching a cold by 58 per cent. It also reduces the duration of a cold by 1.4 days.
Echinacea, which is also known as purple conflower, was used by the Plains Indians of America before it became a popular remedy in Europe in the 1930s.
