Cold and flu season are upon us, that time of year when body aches, fever, chills and nasal congestion combine and can stop you in your tracks, leaving you bedridden for days. Statistics show that the flu annually sickens millions of Americans, kills tens of thousands, and results in billions of dollars in medical expenses and sick days. “Complications arising from the flu can become serious,” says Dr. Suhyun An, an expert on regenerative medicine and co-author of Demystifying Stem Cells: A Real-Life Approach To Regenerative Medicine. To feel better and get back on your feet, she recommends numerous natural cold and flu remedies to alleviate your symptoms:

Vitamin C. Some studies indicate that Vitamin C can shorten the lifespan of a cold and boost your immune system. “The best way to get it is through your diet; the fresher the food, the better,” Dr. An says. “Oranges, limes, lemons, grapefruits, leafy greens, and bell peppers are all good sources of vitamin C. Be careful with supplements because they can lead to upset stomach and kidney stones.”

Honey. Honey has natural antiviral and antimicrobial properties. “Drinking honey in tea with lemon can ease sore throat pain,” Dr. An says. “Research suggests that honey is an effective cough suppressant, too. Honey often contains Clostridium bacteria, so never give honey to a child younger than 1-year-old because infants’ immune systems aren’t able to fight them off.”

Chicken soup. This popular cold and flu remedy helps because hot liquids reduce mucus buildup and keep you hydrated. “Chicken soup, in particular, has anti-inflammatory properties, which help reduce a cold’s unpleasant side effects,” Dr. An says. “Keep some in the freezer or even canned for flu season. It’s quick to prepare that way and soothing to eat.”
