By definition, bronchitis is an inflammation of the lining of the bronchial tubes, which are responsible for carrying air to your lungs and waste out of the lungs. The body's response to the inflammation is to produce mucus. . . lots of it. People who have bronchitis often cough up thick discolored mucus.
Acute bronchitis usually comes from a respiratory infection and generally improves within a week to 10 days. Most people who have it just think they have a chest cold and don't use the word 'bronchitis' to describe what's going on. A respiratory infection centered in the chest like this that doesn't clear within 10 days generally needs a pharmaceutical intervention. There is also a risk of developing pneumonia.
Chronic bronchitis is a more serious condition. This is constant irritation and inflammation in the bronchioles, often resulting from smoking or environmental exposure to pollutants such as smoke particles in the air, atmospheric pollutants, asbestos, etc. Repeat bouts of bronchitis require medical intervention. People with recurrent bronchitis are frequently diagnosed with chronic obstructive pulmonary disease (COPD).
A protocol for these patients that gives quick relief:
I would add points that support the body as well such as Dr. Robert Chu's WTH protocol and perhaps Four Horses needled at the deepest level on one side to further boost immunity.
