During ancient Egyptian times, garlic was used to help heal infections and wounds.  Since then, science has shown that garlic’s sulfur compounds increase the production of virus-killing antibodies by 40% – often within 48 hours.  Getting the benefit is as simple as adding a clove or two of garlic to your favorite dressings and dishes, say scientists reporting in the Journal of Immunology Research.  Hint:  Letting chopped garlic rest for 10 minutes before cooking enhances its potency.
