Using steam mixed with herbs and essential oils can help relieve cough, sore throat, or congestion in the sinuses and lungs (sinusitis, bronchitis). It is particularly effective for sinus and lung areas because you can breathe directly through your nose or into your lungs to expose your tissues to the anti-infective properties in the herbs and oils.
Fill a pan with filtered water (tap water contains chlorine that you will be breathing in the steam) and bring to a boil.
Take off the burner and added a couple tablespoons of oregano and thyme. You could also add 1-2 drops of oregano oil or 1 ADP tablet and 1-2 drops of eucalyptus oil into the water.
Find a comfortable location, place a hot pad down to put the pan onto, cover your head with a towel and breath in through your nose or mouth or both. As the water cools and the steam recedes move you face closer to the pan. Continue to breath the steam until it has cooled and the steam is gone.
