When children have a bad cough, they can use prescriptions such as Sichuan peppercorn sugar pear and honey radish juice to relieve cough symptoms, but there is no quick remedy for cough. Because children are relatively weak, in addition to prescriptions, they should also seek medical attention to identify the cause of their cough. Common causes include foreign body inhalation, inflammatory reactions and allergic reactions, which should be treated according to the cause under the guidance of a professional doctor. I. Prescriptions 1. Snow pear, rock sugar and snow pear: cooking snow pear, rock sugar and snow pear can be used to promote the lung, stop coughing and resolve phlegm, which in turn can alleviate children’s cough. 2. Honey and radish juice: honey with radish juice can be used to remove wind and heat, resolve phlegm and stop coughing, which can be consumed in moderation when children have a bad cough, and can to some extent reduce the effect of coughing. Foreign body inhalation: Children sometimes inhale some dust, atmospheric particles or pollen by mistake, which can trigger a cough when the foreign body adheres to the respiratory mucosa. For larger foreign bodies that are likely to cause damage to the throat, it is recommended that the blocked foreign body be removed under the guidance of a doctor. 2. Inflammatory reaction: When a child’s immunity is relatively low, pathogenic microorganisms such as bacteria and viruses can invade the respiratory mucosa, easily leading to inflammatory diseases such as rhinitis, tracheitis or bronchitis, pleurisy, pneumonia, etc. When the body’s antigenic tissues cannot play a good role in resisting cough. At this time, antibiotics and other drugs should be applied under the guidance of a doctor for anti-inflammatory treatment; 3. Allergic reactions: If the child is allergic himself, then after contact with allergens, an antigenic or non-antigenic stimulus will be produced and lead to the appearance of a cough. In addition, allergic asthma and cough variant asthma are also part of allergic cough, and the typical symptom is coughing. If the symptoms disappear gradually after blocking the allergen, no special medication is usually needed, but if the symptoms are severe, anti-allergic treatment with loratadine and tranylcypromine can be administered under medical supervision. This may irritate the pharynx and cause a cough. Proton pump inhibitors, mucosal protectors, and H2-blockers can be used to relieve cough symptoms in these children. If a child has a simple cough, it is a normal immune response of the body and can be treated without special treatment. It is important to keep warm, drink plenty of water and eat a light diet and avoid spicy, stimulating, cold and greasy foods.
