What is the reason for the baby's clear nasal discharge?

Patient's question:

Patient Age: One and a half years old
Symptom Description: One and a half years old, with a runny nose, no coughing, no fever
History of Treatment and Effect: Taken oral Xinqin Granules
Help Needed: What is going on?

Doctor's answer:

Hello: Based on the symptoms you described, it seems like your baby has a viral cold. You can give him Xinqin Granules and add some Ribavirin or Antiviral Oral Liquid. 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 (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 in a pot. Take the soup 3 times a day, with no limit on the amount.
Wishing your baby a speedy recovery.
