A child’s cough at night is a cold cough because, as the old saying goes, a daytime cough is a fire in the heart and a nighttime cough is a cold in the back. It means that most coughs during the day are fire, and most coughs at night are too cold. If there is phlegm, it is definitely inflammation, and treatment to clear heat and resolve phlegm must be done. You can take Monkey Jujube San or compound Fresh Bamboo Li, etc. You can also take Chuanbei Loquat Paste and Amoxicillin Granules, or you can use dietary therapy to treat it. Steaming garlic water is done by putting 2-3 cloves of garlic into a bowl, adding half a bowl of water and steaming it for 15 minutes. Give it to your child 2-3 times a day. To roast oranges, put the oranges on the fire and keep turning them, and when they are hot, you can eat them. Garlic water can be eaten with roasted oranges with very good results. After coughing, drink more water and do not eat spicy and stimulating, too sweet, too salty and too sour food.
