Chronic cough is one of the common diseases in pediatrics

and its occurrence

development and regression are closely related to the theory of xuanfu. Our team believes that the core pathogenesis of this disease is the deficiency of vital qi and the invasion of evil qi

resulting in a loss of control of the xuanfu.Among them

the deficiency of zang-fu organs and the loss of nourishment of the xuanfu are the basis of the disease; the accumulation of phlegm and food and the stagnation of the xuanfu are the root cause of the disease; the wind evil triggers the xuanfu to be the cause of the disease.In children

the lung

spleen and kidney are often deficient

making it easy for the xuanfu to lose its nourishment

which in turn affects the function of the xuanfu in transporting fluids

and when the xuanfu is stagnant due to deficiency

evil qi has an opportunity to take advantage of it; In addition

if the spleen and stomach are not nourished

and the transportation and transformation are not normal

it is easy to accumulate dampness and produce phlegm

or if food stagnates in the middle jiao and stagnates in the xuanfu channel

it will affect the smooth flow of qi and lay the hidden danger for the development of disease; If the cough is triggered by wind pathogen

the internal and external evil qi will interact with each other and the xuanfu will malfunction

resulting in the failure of lung qi to diffuse and purify and coughing

and the condition will linger.In treatment

our team adopted the principle of promoting the situation and removing the stagnation in the xuanfu by dispelling wind evil

resolving phlegm and removing stagnation

and reinforcing vital qi and supplementing deficiency to open up the xuanfu. At the same time

we pay attention to the application of the characteristic medicine to unblock the xuanfu

especially the medicine to regulate qi to unblock the xuanfu

the medicine to dredge the meridians to unblock the xuanfu and the medicine to invigorate the blood to unblock the xuanfu

so as to restore the function of the xuanfu of the lung

then the disease can be cured.
