Hello, my baby is one and a half years old. Why is it constantly running clear nasal mucus? Thank you

Patient's question:

Patient Age: One and a half years old
Condition Description: At one and a half years old, the patient has a runny nose but no coughing or fever.
History of Treatment and Effect: Taken oral Xinqin Granules.
Help Needed: What is going on?

Doctor's answer:

Hello: Based on your description of the symptoms, it seems like your baby has a viral cold. You can give him Xinqin Granules and add some Ribavirin or Antiviral Oral Liquid. During this time, make sure he drinks plenty of water, eats more fresh fruits and vegetables, and avoids spicy and irritating foods. This is a typical summer cold, often caused by getting cold.
According to your description, if the symptoms are caused by bronchitis or pharyngitis due to a cold (cough, runny nose, low fever), you can try a dietary remedy:
5 olives and 200 grams of white radish. Wash the white radish, cut it into small pieces, and cook it with the olives as a soup. Take it 3 times a day, with no limit on the amount.
Wishing your baby a speedy recovery.
