20 Home Remedies for Fighting a Cold
Oranges

Oranges are chock-full of vitamin C, which plays an important role in your body. Vitamin C can prevent sickness, provide relief for chest congestion and infections, and shorten the length of your cold.
You can take vitamin C supplements or just reach for a big, juicy orange to get your nutrients. If you prefer, you can drink orange juice as long as it doesn't have a ton of added sugar.
