Nasal congestion is the most common clinical symptom of nasal diseases. Various disorders, such as rhinitis, sinusitis, nasal foreign bodies, and even nasal tumors can cause nasal congestion. In terms of colds, clinically it mainly refers to an upper respiratory infection caused by a viral infection. Therefore, nasal congestion alone cannot determine which type of cold it is. The types of colds, in modern medicine, refer to upper respiratory infections. In traditional Chinese medicine, they are divided into colds caused by wind-heat and colds caused by wind-cold. Merely from the symptom of nasal congestion, it is impossible to determine the type of cold. Therefore, in clinical practice, the main focus for treating nasal congestion is symptomatic treatment, which may include the use of medications to constrict the nasal blood vessels and clear the nasal passages.
