Physiological functions of spleen and liver

"unification" means unified management and control. Spleen controlling blood means that the spleen has the function of controlling and controlling blood to run in the meridians without overflowing outside the pulse. Skin is not only the source of biochemistry, but also has the function of controlling blood, which is mainly achieved through the functions of' air intake' and' spleen enhancement'. When the spleen is healthy and healthy and rises normally (spleen rising), the blood is controlled by the spleen and can run normally in the vein without overflowing. If the spleen is weak, loses its control function, and the qi does not absorb blood, the blood will leave the vein, resulting in various hemorrhagic diseases, such as long-term hematochezia, metrorrhagia and so on. Clinically, the method of "invigorating spleen and replenishing blood" is often used to treat bleeding caused by "spleen failing to control blood" and has achieved certain curative effect. Therefore, there is a saying that "treating blood first treats spleen". Liver storing blood means that the liver has the function of storing blood and regulating the amount of snow. Blood stored in the liver is not simply stored. Because the blood flow in different parts of the human body often changes with different physiological conditions, the liver can store blood by adjusting the blood flow according to the dynamic and static needs of the body. In other words, when the human body is resting and sleeping, the body's demand for blood is reduced, and excess blood is hidden in the liver; When working and working, the body's blood demand increases, and the liver discharges the stored blood to meet the needs of physical activities. The ancients said that "the liver stores blood, the heart does it, and people move blood to the liver", which is the truth. If the blood storage function of the liver is abnormal, it will cause blood diseases. For example, in the deficiency of liver and blood, women's eyes can be seen dim, muscle spasms, unfavorable flexion and extension, less menstrual flow and even amenorrhea. If the liver-qi goes against the trend, women may suffer from vomiting blood, metrorrhagia and other diseases.
