Nasal congestion is a common symptom, which is the result of inflammation of the nasal mucosa and swelling of the turbinates. Nasal congestion is often a symptom of the beginning of a cold or rhinitis, but if the cold or rhinitis is not cured in time, it may become chronic rhinitis.
In the book “Shiming” from the Eastern Han Dynasty, it is written that “rhinitis for a long time, congestion of the nose for a long time, and then suffocation.” Ancient Chinese has many expressions of suffocation to describe the symptoms of nasal congestion.
