Drink tea. Hot liquids in general help to dissolve the mucus that causes chest congestion, but tea offers a double punch by adding in helpful herbs and spices that can ease chest pain and congestion. Brew up a cup of peppermint, ginger, chamomile, rosemary, or ginseng tea to drink several times a day.
Nasal congestion can also be relieved using home remedies such as burning a teaspoon of cardamom seeds on hot coals and breathing in the resulting smoke, dripping saline solution into each nostril and blowing your nose, inhaling black pepper (or the smoke released by burning five or six black pepper seeds), adding a few more pillows under your head when you sleep, and increasing the level of moisture in the air using a vaporizer.
