20 Home Remedies for Fighting a Cold
Peppermint Oil

Peppermint oil and other essential oils have been used to treat ailments for a long time, including the common cold. This essential oil has antiviral and antibacterial properties that can kill airborne germs, which makes it a natural nasal decongestant. It is also an expectorant for mucus and is effective for relieving headaches.
You can use an oil diffuser to put out puffs of symptom-relieving air at timed intervals or even inhale directly from the bottle to relieve congestion. Another method is to get a warm, damp cloth, put a few drops of the oil inside, and place it on your chest for deep congestion relief.
