During acute febrile diseases such as measles, encephalitis and meningitis, external Heat can invade and penetrate deeply into the Blood level and stir up the Wind. It is more common among children.

If excessive Liver Qi rises, it can cause Liver Yang Rising. If not treated for some year, it agitates internal Liver Wind. Eating in a hurry, eating while working or getting angry at meal time can lead to the pattern.

Emotional problems, such as anger, frustration and resentment, are the most obvious causes for this pattern, especially if these emotions are suppressed over a very long time. Anger drives Rebellious Liver Qi upwards and cause Liver Yang Rising. If not treated for some year, it agitates internal Liver Wind.

Excessive physical exercise mainly harms the Spleen Yang. As a result, the Spleen's foods transforming and transporting function is impaired, thus less Blood can be generated and stored in the Liver.

Excessive exercise also injures the sinews. Since the Liver controls, moistens and nourishes sinews, which in long run, can give rise to Liver Blood Deficiency. If not treated for years, it can eventually agitate internal Liver Wind.

The Liver stores the Blood. Therefore a serious haemorrhage, such as long term heavy periods, can lead to Liver Blood Deficiency. If not treated for many years, it can agitate internal Liver Wind.

Heat in the Liver (and subsequent Wind) can arise from excessive intake of alcohol, drugs, caffeinated foods and drinks, hot foods such as lamb and beef and fried and greasy foods.
