The harmonizing method is one of the important therapeutic principles in traditional Chinese medicine （TCM）. It refers to the use of principles such as harmony or reconciliation to achieve the neutralization of

yin

and

yang

. The spleen and stomach， located in the middle energizer， are the sources of

qi

and blood transformation and the key hub for the movement of

qi

in the body. Professor WANG Shouchuan believes that the clinical incidence of spleen and stomach diseases in children is high， with diverse pathogenesis， commonly involving disharmony among the

Zangfu

organs， mixed deficiency and excess， a combination of cold and heat， or imbalances between nutrient and defense aspects. The harmonizing method plays a significant role in the treatment of spleen and stomach diseases in children. In clinical practice， it is essential to apply methods such as harmonizing the spleen and stomach， regulating cold and heat， inhibiting the liver and strengthening the spleen， and harmonizing nutrient and defense aspects， along with their variations.
