Chest congestion occurs when fluid and mucus buildup in the lungs, causing tenderness, pain, coughing and difficulty breathing. Chest congestion can produce a productive wet cough or a dry cough. Anyone who has had lung congestion will tell you that it can be painful and exhausting as constant coughing plagues your body.
Common causes of lung congestion
Bronchitis can be caused by either viral or bacterial inflammation of the primary airways in the lungs or bronchial tubes. It can develop from a cold, or other respiratory infections.
Pneumonia can be caused by bacterial, fungal, parasitic or viral infections in the lungs. Pneumonia can vary from very mild to life-threatening.

Oregano Benefits: A Natural Remedy for Congestion
Many people may think of oregano as a herb for cooking. Its medicinal properties, however, are quite extensive. With its antibacterial, anti-inflammatory and antioxidant benefits, some of its uses may surprise you. It is frequently associated with respiratory and immune health. 
Oregano is a great source of vitamins A, C, E, and K, as well as an excellent source of fiber. This herb is also high in folate, iron, manganese, magnesium, potassium, calcium and B6.
Oregano oil as potent as antibiotics
While there are many benefits to oregano, its antibacterial properties are a healthier alternative to traditional antibiotics for minor infections, which can lead to decreased vitamin absorption, antibiotic resistance, as well as the killing of beneficial gut bacteria. 
There are many components that make oregano such a potent and healing herb. Two of the more potent chemical compounds are thymol and carvacrol. The PubMed database references over 1,000 studies involving carvacrol and just under 3,000 for thymol. Why are these two components so important? Carvacrol is effective against numerous bacterial infections, and thymol boosts your immune system and encourages healing. In fact, this study showed significant and immediate improvement in symptoms of upper respiratory illnesses. 
When to use oregano
It’s always best to take proactive measures. As soon as you begin to feel a cold or flu coming on, sip on some oregano tea. Oregano will boost your immune system, as well as relieve congestion and fatigue that can be associated with a cold or flu. Oregano is also a great fever reducer.
