Syndrome differentiation and treatment of allergic rhinitis in children should be based on the theory of "five viscera correlation" combined with the physiological characteristics of deficiency and excess of the five viscera of children; make it clear that the location of the disease is inseparable from the nasal orifice and the pathogenesis is inseparable from the five viscera; in terms of syndrome differentiation and treatment, the viscera should be regulated and the orifice should be regulated via the viscera; on the basis of identifying the cause and examining the pathogenesis, attention should be paid to regulating the lungs and spleen, tonifying the kidneys, clearing the heart, and soothing the liver, so as to restore the harmony of the viscera and the unobstructed nasal orifice.
