Cold is one of the most familiar diseases to the general public, and everyone may have experienced it in one way or another and have different personal experiences. The symptoms of cold can vary from person to person due to different physical qualities and seasons, but the common clinical manifestations are itchy nose, sneezing, nasal congestion, runny nose, body discomfort, fever and headache, while in children the systemic symptoms are often heavier, manifested as high fever, convulsions, vomiting and diarrhea are not uncommon. If the cold is not treated properly, it may lead to acute sinusitis, otitis media, tonsillitis, pharyngitis, tracheobronchitis and pneumonia, posing a threat to health. As we all know, colds can develop in all seasons, but more often in winter. They are acute upper respiratory infections caused by viruses, involving hundreds of viruses, among which rhinovirus, adenovirus, respiratory syncytial virus, influenza and parainfluenza virus are the most familiar and common types of viruses. Although Western medicine has a certain understanding of viruses, there is still a considerable lack of drugs for viral infections and the therapeutic effect is very unsatisfactory. The understanding of cold and flu is different between Chinese and Western. Cold in Chinese medicine is “wind and nasal congestion” category, according to the different symptoms, Chinese medicine to cold into wind-heat and wind-cold two types of implementation of evidence-based treatment, unique, unique, clinical results are also more satisfactory. Some people rarely catch a cold, while others catch it frequently. Parents of small children who always have colds throughout the year may ask, “Is there an ideal way to prevent colds?” Clinical practice proves that there is. In addition to personal hygiene and warmth, ventilation, exercise and nutrition, children who are prone to sweating and catching colds (lung qi deficiency according to Chinese medicine) can choose Yu Ping Feng granules (made up of three herbs Astragalus, Atractylodes and Fang Feng, which have the effect of benefiting qi, fixing the surface and stopping sweating) to be taken orally, 1 packet (5g) per day for a month, which often has unexpected effects. Of course, individuals and diseases are unique and not uniform, so the above experience is for reference only.
