Liver storing blood means that the liver has the functions of storing blood, preventing bleeding and regulating blood volume. The liver governs the discharge, which means that the liver has the functions of discharging, relaxing and smoothing, so as to keep the whole body qi flowing smoothly, dispersing without stagnation, and dispersing without depression.
The relationship between liver excretion and blood storage: the liver is in charge of both excretion and blood storage.
Storing blood is the material basis of stopping diarrhea, and stopping diarrhea is the functional expression of storing blood. The release of liver depends on the nourishing function of blood and the normal function of liver. Therefore, there is a close relationship between the liver's drainage function and blood storage function.
As far as the release of liver is concerned, physiologically, if the liver is controlled to release and the qi is regulated smoothly, the blood can return to the reservoir and get normal regulation. The operation of blood needs not only the promotion of heart and lung qi and the control of temper, but also the regulation of liver qi to ensure the smooth flow of qi and prevent blood stasis. Pathologically, liver-qi deficiency can affect the return and operation of blood.
If the liver is depressed and qi stagnates, blood stasis, that is, qi stagnation leads to blood stasis. If there is too much drainage, the liver qi will rush up and the blood will rush up with the qi, which can lead to bleeding.
As far as the liver's blood storage function is concerned, physiologically, the liver can store blood, and blood can nourish the liver, so that the liver yang will not be excited, ensuring the normal function of the liver to control excretion.
Under pathological conditions, the liver does not store enough blood or the liver does not store blood and bleeds, which eventually leads to liver blood deficiency. Liver blood deficiency, if the blood fails to nourish the liver, it will lead to insomnia and dreaminess, and women's irregular menstruation will appear one after another.
