I've gotten rid of stuffy nose before by placing some peppermint tea bags in a heat proof bowl and then adding boiling water to the bowl of tea bags.
I then put my face over the bowl and breathed in the peppermint and the steam from the boiling water and my nose was cleared up within a few minutes and I no longer had a stuffy nose.
You can also clear up a stuffy nose by using some Vicks Vapor Rub on your chest.
Another good natural way of getting rid of a stuffy nose is to use a Neti pot and rinse the inside of your nose out to clear up any blockages.
It's a good idea to rinse your nose out often with the Neti pot to help prevent a stuffy nose as well.
