Non-alcoholic fatty liver disease is caused by multi-factors

and is closely related with metabolic diseases

such as diabetes

coronary heart disease and obesity. Chinese medicine mainly treats it from the views of turbidity toxin

distention and fullness

and phlegm turbidity etc. The authors think that turbidity toxin goes through the process of non-alcoholic fatty liver disease

with different cause and pathogenesis in different stages

showing a progressive evolution course. Adopting different treating measures based on pathogenesis features in different stages

shows the thought of treating according to syndrome differentiation

in order to achieve the best treating effects.
