One natural way.
Agree w dr. Kam. Neti pots 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.
