Ginger is a traditional cold remedy in Chinese medicine, says Charles Lo, M.D., a physician specializing in preventive medicine in Chicago. “Ginger is considered to have warming properties and is the first choice for cold symptoms like chills, low-grade fever and headache,” he says.
Dr. Lo recommends taking ginger at the first sign that a cold is coming on. At different times throughout the day, chew on three or four very thin slices of fresh ginger root, he suggests. You can supplement this daily chew with hot ginger tea, which is especially soothing if you are bothered by nasal congestion.
