Are you suffering from stubborn sinusitis, cold and flu? If yes is your answer, then your remedy lies in garlic. Taking 2-3 cloves of raw or cooked garlic a day or sipping some garlic tea (with a touch of honey or ginger to lift up the taste) is not only going to relieve a stuffed nose and cure the cold, but also build your immunity against these frequent visitors over time, according to Dr. Shikha Sharma, Delhi-based Health and Wellness Expert.
