A clear-colored runny nose belongs to a wind-cold cold, and the nature of the runny nose can diagnose wind-cold or wind-heat. Wind-cold colds are characterized by headache, fever, chills, stuffy nose, runny nose, and clear runny nose. Wind-heat colds are characterized by a stuffy and runny nose, yellow and pusy nasal discharge, accompanied by headache and fever, and no symptoms of cold. A runny nose is a wind-cold cold, mostly seen at the beginning of a viral cold, a cold caused by simply feeling wind-cold. In addition to the nature of the runny nose, it is also important to look at other accompanying symptoms, such as whether there is congestion and edema in the throat, as well as coughing and coughing up sputum, and the color and nature of the sputum. Simple wind-cold cold should be kept warm, pay attention to avoid wind and cold, and can use ginger soup and brown sugar to drink, which can relieve the symptoms of wind-cold cold. Clinically, colds are mainly internal heat and external cold, and simple wind-cold colds are not common.
