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.
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.
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.
