Monism of Qi is the materialistic foundation of the theoretical system of Chinese medicine， it is also the basic concept of life. Qi is the primordial of the universe， and the only form of the universe and all things primitive.

A lot of Clinical experience has proved that Chinese medicine could be an ideal prevention and control for a variety of acute and difficult diseases， including infant hepatitis syndrome.
