Through the analysis of the causes of the sufficient ascending and dispersive sweet and warm

and insufficient clearing and resolving cold and cool in Treatise on Spleen and Stomach（《脾胃论》）

it is believed that the historical period of LI Dongyuan with many "starvation

hardship

and forced labor" is the important factor of the formation of core concept of "internal injury of spleen and stomach

all diseases occurred". With the change of society

the etiology and pathogenesis has undergone significant changes

and the spleen is gradually becoming excessive

and"qi astringent and blood turbid". Therefore

the internal retention of turbidity toxin has become an important mechanism of spleen and stomach lesions today. For example

the understanding and study on spleen and stomach lesions by way of thinking based on the combination of disease differentiation and syndrome differentiation has far more extensive connotation than the "spleen and stomach qi deficiency" and "yin fire" in the LI Dongyuan era. Modern spleen and stomach disease is a group of diseases involving multiple systems. The method of differentiation and treatment should also advance with the times. It should be treated with sweet

warm

pungent and dispersive combined with cold

cool

clear and resolving

to explore the purpose of LI Dongyuan’s spleen and stomach theory and to learn his academic thoughts

so as to help solve the problem of "the ancient formula cannot treat modern diseases".
