Bronchitis is a respiratory disorder in which the air passages, that connect the windpipe to the lungs are swollen. In most cases, a viral infection is responsible for causing bronchitis. Symptoms include mucus producing cough, chest tightness, and shortness of breath. Chronic smoking and exposure to toxic gases increases the risk of bronchitis. Apart from taking prescribed treatment, natural remedies too can contribute to relieve discomfort of the respiratory tract.
