Syndrome of endogenous liver wind is the syndrome marked by dizziness, convulsion and tremor. According to the causes, this syndrome is clinically further divided into syndrome of liver yang transforming into wind, syndrome of extreme heat generating wind, syndrome of yin asthenia disturbing wind and syndrome of blood asthenia generating wind.

Clinical manifestation:
In wind syndrome caused by hyperactivity of the liver -yang:serous dizziness, feeling heavy in the head, and headache when one shakes one's head, stiff neck and numb limbs, trembling of hands and feet, inarticulateness, red tongue,taut and thready pulse, sometimes, sudden fall into a swoon with contraction of hands and feet, or convulsion, facial hemiparalysis, and hemiplegia. In occurrence of wind syndrome in case of overabundance of pathogenic heat: high with eyes looking upward and teeth closed tightly, deep red tongue with yellow fur, taut and rapid pulse. In wind-stirring syndrome caused by yin deficiency: hands and feet trembling accompanied with symptoms of deficiency of the  liver-yin. In endopathic wind syndrome caused by symptoms caused by blood deficiency: numbness of the limbs and stiffness of the joints, trembling of hands and feet accompanied with symptoms of deficiency of the liver blood.

Analysis of the symptoms:
Wind syndrome caused by hyperactivity of the liver-yang is often associated with long-standing yin deficiency of the liver and kidney, which makes the abnormal rising of the liver-yang so uncontrollable that liver-wind is stirred, so wind occurs. Wind syndrome due to pathogenic heat is brought about by excess of pathogenic heat which ignites the liver channel. The syndrome of wind-stirring caused by yin deficiency occurs in most cases at the late period of febrile diseases in which yin-fluid has been exhausted, tendons and vessels are not nourished and wind is stirred. The syndrome of endopathic wind caused by blood deficiency is due to loss of blood, or blood deficiency on account prolonged illness as tendons can not be nourished by blood.

Key points for syndrome differentiation:
serious dizziness, convulsion,trembling and numbness--all these are characteristic of the signs and symptoms of this syndrome.
