If a child has purulent nose, first consider whether it is caused by wind cold or wind heat cold. If you have a cold due to wind chill, you should do cold dispelling treatment. If you have a cold due to wind heat, you should remove the fire. If your child has rhinitis, you should drink anti-inflammatory drugs to deal with it. At ordinary times, pay attention to the maintenance and warmth, do not catch a cold, and eat more light fruits. Vegetables can properly supplement meat and eggs to strengthen the body and improve immunity. If the problem is not serious, you can use a hot towel to compress your nose.
