Children’s visceral organs are fragile

and their morphology and physiological functions are not yet full. As a delicate organ

the lung is most vulnerable to evil. The lung suits dampness but is unaccustomed to dryness and is therefore susceptible to disease caused by dryness evil. In the pathogenesis of mycoplasma pneumoniae pneumonia (MPP) in children

dry cough is the main clinical symptom

which is consistent with the pathogenesis of lung injury caused by dryness evil. MPP in children is caused by dryness evil

and can be divided into two pathological states

namely

deficiency and obstruction of fluid

according to the depth of the disease and the degree of injury to fluid. Based on this

the theory of "flowing fluid to moisten dryness" is proposed. In this theory

moistening is applied to maintain the flow of fluid

so that the meridians can be opened

fluid can be transported

and the organs can be irrigated and nourished. Our team believe that dryness evil injuring the lung fluid and the obstruction of fluid are fundamental factors in the development of MPP in children. External dryness evil attacking the body

internal dryness evil burning the fluid

and evil becoming poisonous over time are key to the de-velopment of MMP. Treatment should consider the physiological and pathological characteristics of the children and be performed under the guidance of the theory of "flowing fluid to moisten dryness

" including applying the moistening method to moisten the lung

nourish the fluid

and dispel the evil. This should be performed in combination with the tonic method

clearing method

and lowering method. By combining multiple method

the lung fluid will be full

the evil will be removed

and the body will become healthy.
