The clinical experience of Professor YAN Huimin in the treatment of infantile cholestasis liver disease（ fetal jaundice） was summarized. It is believed that the disease is caused by dampness pathogen

which is the main cause of fetal jaundice. Dampness pathogen can block the qi movement in both yin jaundice and yang jaundice

resulting in unsmooth blood circulation and blocked blood stasis. The disease is caused by bile overflowing out of bile duct to the skin

but dysfunction of spleen in transportation

dysfunction of stomach in harmonizing and descending

and internal generation of dampness pathogen are the root causes. In clinical practice

the four diagnostic techniques should be combined

and yin and yang syndrome should be differentiated firstly. The color of the stool and the thickness of the tongue coating are the main basis for syndrome differentiation. Treatment is often to remove dampness

and take into account the cold and heat

and the method of promoting blood circulation to remove blood stasis is going throughout the treatment; at the same time

the method of dispersing stagnated liver qi for promoting bile flow is strengthened to cure the disease and solve the root causes. In the course of treatment

it is necessary not to forget to concern and protect the healthy qi

prevent medicinal pathogen from damaging the healthy qi. Meanwhile

from the first small beginnings one can see how things will develop. We should not only prevent disease

but also promote the recovery of the disease

so as to prevent diseases from exacerbating

and promote the recovery of diseases.
