Children's liver fire can be divided into two types: excess and deficiency. Deficiency fire is manifested as upset, dry mouth, low fever, night sweats, etc. Excess fire is manifested as dry mouth, recurrent oral ulcer, short and red urine, upset and irritable. You can eat: 1, fresh fruit. Such as water chestnut, pear and grapefruit. Water chestnut juice is rich and slightly cold, which is very suitable for children who are upset and thirsty, have sores on their mouths and dry urine. Pears and pomelos can moisten the liver and lungs, and besides clearing away heat, they are very suitable for babies with lung heat, cough and yellow phlegm, dry throat and pain. 2. Eat less snacks. Try to make and buy foods that are easy to get angry, such as braised and fried, for children as little as possible. Preschool children must eat less food with shells such as flowers and melon seeds. Children should be encouraged to eat more fruits and vegetables at ordinary times, and don't let children drink too much cold drinks in summer. 3, give more vegetables that clear the liver fire. Such as celery, bitter gourd, eggplant, water bamboo and Chinese cabbage. 4, drink more mung bean soup or mung bean porridge, mung bean tastes sweet and cold, clears away heat and relieves annoyance, can cool and detoxify, and is most suitable for children who are upset and grumpy. If the situation of liver fire does not improve, you can do lower abdominal gymnastics. Generally, you can gently rub your abdomen about half an hour before meals and before going to bed and getting up. Rubbing your abdomen can improve the peristalsis of the large and small intestines and enhance the secretion of gastrointestinal organs. At the same time, you can listen to some music that makes people feel happy and adjust your sentiment. After a period of time, the phenomenon of liver fire will disappear automatically.
