Garlic

Apart from generally being good to keep cold and cough at bay, garlic also acts as an immunity supplement. This flavorful food has compounds that help the immune system fight germs. Taking 2-3 cloves of raw or cooked garlic a day or sipping some garlic tea with a touch of honey or ginger is not only going to relieve a stuffed nose and cure the cold but also build your immunity against these frequent visitors over time.
