This paper discussed TONG Xiaolin's experience in treating obesity from the “earth congestion”. The disease location of obesity is at middle

jiao

（spleen and stomach）. The skewed state of obesity is mainly manifested as the “congestion state” of cold-damp， phlegm-turbidity， damp-heat and other pathological products being accumulated in the middle

jiao

（spleen and stomach）. It is believed that obesity is caused by many factors such as congenital endowment， cold drink， and improper diet， of which

gao

（膏）-turbidity is the direct pathogenic factor. The accumulation of

gao

-turbidity makes

qi

mechanism get imbalanced， and then earth

qi

is disordered and blocked， thereby the state of “congestion” is easily produced. As the

gao

-turbidity is deposited for a long time， the pathology evolves from absolute excess to relative excess， and deficiency results from excess. The treatment should put focus on regulating “earth congestion”， accelerating

gao

and directing the turbid downward from middle

jiao

（spleen and stomach）. The seven methods of regulating “earth congestion” is commonly used in clinical practice to resolve constraint and dredge the bowels， remove stagnation and activate spleen， thereby restoring the function of the spleen and stomach.
