The relationship between Qi and blood in traditional Chinese medicine

According to traditional Chinese medicine, Qi is the commander of blood, and blood is the mother of Qi, which means that the two are interdependent. Qi and blood can be transformed by each other, so if one of them is weak or insufficient, the other may also be affected, and symptoms of Qi and blood deficiency may occur. In addition, Qi has a promoting effect. If the promoting energy is insufficient after Qi stagnation and blood stasis or Qi deficiency, the circulation of blood will also be affected, and the situation of Qi deficiency and blood stasis or Qi stagnation and blood stasis will occur. In addition, blood has the function of nourishing and moistening. If the blood is insufficient, it cannot restrain the flow of qi in and out, which may lead to the situation of qi and blood rising.

In the theory of traditional Chinese medicine, the body's Qi and blood are interdependent. Only when the two exist at the same time can a person be healthy. Air can replenish blood, circulate blood, and absorb blood, while blood can generate heat and carry Qi. In clinical medicine, many weak patients have weak blood and qi. Because weak patients have poor gastrointestinal function, they cannot convert food into energy and water and grain accurately, and cannot make the body's blood flow and function normally. A series of related symptoms appear, such as people with weak constitution will experience general fatigue, pale complexion, and even various physiological functions and organs will be in decline.

For special groups, like women, the blood qi function also determines their health condition. Blood qi disorder can easily affect women's menstruation, pregnancy and related physiological needs.

Qi and blood are the basic substances that make up the body, and are the material conditions for the internal organs, meridians, and tissues of the human body to carry out physiological activities. Qi is Yang and blood is Yin. The two are different but also related, "Qi is the commander of blood, and blood is the mother of Qi." First of all, air can replenish blood, and the formation and transformation of blood is inseparable from the vaporization of air. Secondly, air can circulate blood, and blood belongs to Yin and is quiet. Blood cannot be autonomous and completely relies on the promoting effect of qi. Therefore, it is also said that when qi flows, blood circulates, and when qi stagnates, blood stagnates. Thirdly, air can absorb blood, and the retaining function of qi can make the blood flow in the vessels without overflowing out of the vessels. Therefore, when qi cannot absorb blood, various bleeding diseases will occur. Fourthly, blood is the medium of Qi and provides sufficient nutrients to Qi. Qi must rely on blood and body fluids to exist. Therefore, when both Qi and blood are deficient, Qi has no support and will also become weak.
