Chronic rhinitis (CR) is one of the most common nasal mucosal diseases in the world. In China, about 140 million people suffer from this disease. Chronic rhinitis can lead to severe economic and social burden, as well as the potential risk of developing other chronic diseases such as asthma and chronic sinusitis.
