If part of the reason you’re breathing through your mouth is because your nose is clogged, use an over-the-counter medicated decongestant nasal spray or drops to open up airways, such as Afrin or Vicks. “Nasal decongestants work well at eliminating congestion in your nose and drying mucus out,” Dr. Abramowitz says. “This can help you feel better and also decrease postnasal drip.”
Mint has been used for hundreds of years as a health remedy. Peppermint oil might help with irritable bowel syndrome -- a long-term condition that can cause cramps, bloating, gas, diarrhea, and constipation -- and it may be good for headaches as well. More studies are needed to see how much it helps and why. People use the leaf for other conditions, too, but there’s very little evidence it helps with any of them.
