Nowadays, hundreds of millions of people are suffering from chronic respiratory diseases. According to the recent studies, presently 210 million people are suffering from chronic obstructive pulmonary disease (COPD), 300 million people from asthma, and millions of people from allergic rhinitis.

Respiratory system has a great role in our body. Not only it supplies oxygen to various cells of the body, but also it washouts the wastages, supplies air required for speech and filters out infectious agents. So, it is very much essential to protect our respiratory system in all aspects.
