Peppermint is another good option for cleansing your lungs. Peppermint and peppermint oil contain menthol that helps relax the smooth muscles of the respiratory tract. This promotes effortless breathing and helps clear symptoms of any upper respiratory congestion.
A 2010 study published in the Journal of Ethnopharmacology noted that the anti-congestive, anti-spasmodic and expectorant properties of peppermint oil helped relax the trachea in rats.
For strong lungs, chew 3 – 5 peppermint leaves each day.
To treat congestion, add a few drops of peppermint oil to a pot of hot water and inhale the steam.
You can also drink 2 cups of peppermint tea daily. To make the tea, add 1 teaspoon of dried peppermint leaves to a cup of hot water, cover and steep for 10 minutes.
Side Note: Peppermint tea is also very useful for disbursing trapped wind.
