Acute hepatitis is mostly related to the attack of external evils or medicinal poison injury, the evil is full of real, Zhengqi is not weak, generally speaking, the course of the disease is short, the location of the disease is shallow, and the damage to the internal organs of qi, blood, yin and yang is not heavy (except for severe hepatitis). The disease is mostly confined to the liver, gallbladder, spleen and stomach, and the clinical manifestations are dominated by the dysfunction of the relevant internal organs, and the internal injury and deficiency are slight. After the acute phase, the recovery phase may also show signs of impaired vital energy such as weakness and fatigue, loss of appetite and emaciation. After proper management, the disease will be cured soon without leaving any root cause. Chronic liver disease is either insidious in its onset or transformed from acute hepatitis with prolonged or recurrent episodes.

The longer the course of the disease, the deeper the disease, the more organs involved, the worse the prognosis, liver and kidney yin deficiency is the final stage of the development of a variety of chronic liver disease. “Long-term disease will be weak”, “long-term disease will be stasis”, “long-term disease and kidney”, “long-term disease into the network”. Positive deficiencies and evil realities are glued to each other, affecting each other in an intricate manner.
