Phlegm often accompanies colds and other upper respiratory infections. While not a serious health problem, if phlegm is not treated timely, it can clog and irritate the bronchial tubes and in turn cause a secondary upper respiratory infection.
The presence of phlegm is usually indicated by a constant need for throat clearing, constant cough,runny nose, difficulty breathing, feeling weak and, in some cases, fever. Phlegm tends to collect and congest in the chest and throat and is usually expelled through coughing.
Phlegm contains the bacteria, virus or inflammatory cells produced in response to an infection. In addition to infections such as the common cold, flu and bronchitis, phlegm can be caused by anallergic reaction to irritants such as in asthma and hay fever, damaged vocal cords, and excessive smoking.
Dealing with phlegm can be incredibly frustrating and seemingly never ending. But there are effective, natural home remedies that work quickly and without causing side effects.
