Based on the spleen and stomach theory and the unblocking and purging theory

the "harmonizing the center to restore balance" theory is formulated conforming to the needs of social and environmental changes and integrating years of clinical experience in disease differentiation and syndrome differentiation

which advocates that "harmonizing the center" is the basis and "balance" is the aim. By further expanding the application area of spleen and stomach theory and the unblocking and purging theory

the "harmonizing the center to restore balance" theory not only addresses the importance of caring the center-earth

but advocates to harmonize the yin-yang

zang-fu（脏腑）

qi-blood

cold-heat and deficiency-excess to restore the dynamic balance of the body. When treating the spleen and stomach diseases using "harmonizing the center to restore balance" theory

it is held that if zang-fu is taken as the principle

the subtle changes in symptoms should be observed to distinguish the functional state of the spleen and stomach; if qi-blood is taken as the principle

qi stagnation is considered as the common etiology of visceral dysfunction; following the deficiency-excess principle

spleen deficiency is core of the the deficiency syndrome and the deficiency-excess complex syndrome; following the cold-heat principle

warming and clearing methods are combined

and even method is advocated.
