According to traditional Chinese medicine, recurrent respiratory tract infections in children belong to the categories of “deficiency cold”, “prolonged cough”, “deficiency evidence”, “sweating evidence”, etc., commonly known as “susceptible children”. It is mostly caused by the deficiency of the lungs, spleen and kidneys, and the lack of solidity of the external guard, which leads to repeated exposure to external evil. However, some children with recurrent respiratory tract infections can be seen in the clinic with strong appetite, abdominal distension, restlessness at night, teeth grinding, sour breath, loose and sour stools or constipation, easy sweating, red tongue, white or yellowish fur, slippery pulse, etc., accompanied by easy vomiting, fever in the heart of the hands and feet, short yellow urine, low fever, etc. The reason is that with the development of social and economic conditions, the diet structure has changed, and children are fond of fatty, sweet, thick and cold products, which are not well controlled by parents, which hurts the spleen and stomach for a long time, and the transportation and decomposition are not normal, so the food accumulates and turns into heat, and the internal heat accumulates. Treatment: Eliminate food stagnation, and clear internal heat.
