Largest ever clinical study into echinacea finds herbal remedy CAN protect against colds

The herbal remedy echinacea can prevent colds and is of most benefit to people who are prone to them, according to the largest ever clinical study of the herbal medicine.
Researchers found that taking three daily doses of the common remedy for four months reduced the number of colds. The duration of the illness suffered by patients also went down by an average of 26 per cent.
According to the results of tests on 750 people, the treatment also cut the number of recurrent colds suffered by those with weak immune systems or a history of catching several bouts each year by 60 per cent.
Several previous studies, including an overview of evidence by the highly respected Cochrane Library, had suggested that echinacea could soothe symptoms and cut colds short, but there was only limited evidence it could prevent the illness from ever taking hold.
The most recent major paper into the therapy, by the American College of Physicians, had found that it did not prevent colds or significantly reduce the length or severity symptoms.
