Asthma, one of the allergic diseases, affects 300 million people worldwide. The prevalence of asthma in children and adults increases globally by 50% every decade in different countries. Especially, in developing regions such as Africa, Central and South America, Asia, and the Pacific, the prevalence of asthma continues to rise sharply due to the increasing urbanization and westernization. This increased incidence of asthma leads to an increase in the cost of the treatment. Asthma is a complex syndrome with many phenotypes in humans and is characterized by variable airflow obstruction, airway hyper-responsiveness, and airway inflammation, which cause wheezing, coughing, tightness of the chest, and breathlessness.
