How can you clear a stuffy nose?

A neti pot can: Reduce nasal congestion. Mix ¼ tsp salt w 1 cup lukewarm water. More salt can also be used. Place solution in neti pot. Tilt head & pour solution into 1 nostril. Blow nose lightly & spit out any liquid that drains into throat. Repeat on other side. This can be done in the evening before you go to bed & again in the morning. You can watch a video online to get the finer details down. Consider use.
