At the first signs of a cold, consider using A Vogel's Echinaforce drops, a traditional herbal remedy for colds and flu. It helps your body fight the symptoms of these infections, such as coughs and sore throats, by supporting your immune system, helping to maintain your body's resistance. Echinaforce uses fresh extracts of organically grown Echinacea purpurea herb, which has been shown to have almost three times as many active substances as those obtained from equivalent amounts of dried herb.
