Chinese medicine often says that "nourishing blood is nourishing life". Why?

Chinese medicine has a very long history, and its development in China is relatively perfect. Many theories are even difficult to be scientifically explained, but Chinese medicine can only achieve a radical effect on many diseases. Perhaps western medicine will only have an advantage over traditional Chinese medicine in the course of treatment and speed of treatment, but it is relatively impossible for western medicine to achieve such a goal if it wants to eradicate diseases. Only Chinese medicine can have such ability. Then Chinese medicine practitioners often hear this sentence, that is, nourishing blood is nourishing life. In fact, for this sentence, a person with sufficient qi and blood will be particularly energetic, which requires sufficient qi and blood supply to maintain such a mental state. Therefore, nourishing blood is very important for a person. If it is blood deficiency or anemia, it will lead to the decline of physical fitness and resistance, and it is very likely that some chronic diseases or abnormal symptoms in daily life will appear. Many people in life often smoke, drink and stay up late, which will lead to the phenomenon of blood deficiency, so everyone can also look at it in life. These people's living conditions are definitely not good. And if you don't nourish blood, it will lead to dull complexion, easy insomnia and forgetfulness, easy fatigue, repeated ischemia, especially people with blood deficiency suddenly stand up after squatting for a few minutes. Therefore, nourishing blood is nourishing life. If the blood is deficient, there may be very serious heart damage and brain damage. If we don't pay enough attention to it for a long time, it will harm the kidney, liver and various internal organs and produce various diseases. Therefore, Chinese medicine often says that nourishing blood means nourishing life. If insufficient blood gas is deficient in blood, it will cause great burden to the spleen and stomach, and in severe cases, there will be some palpitation and shortness of breath. For young people who work for a long time, it will damage the brain and lead to memory loss, so enriching blood can be said to nourish life.
