Qi and blood in TCM is the general term of human qi and blood. Qi and blood have different functions and are interdependent at the same time, nourishing organs and tissues and maintaining life activities. The gas in the human body is equivalent to an engine. Growth and development, viscera activities, blood circulation and body fluid transport all depend on the stimulation and promotion of qi.

Metabolism is the general name of orderly chemical changes in the body, which is carried out under the catalysis of general enzymes, including material metabolism and energy metabolism, the exchange of material and energy between the human body and the outside world, and the transformation process of material and energy in the body, which is called metabolism.

Traditional Chinese medicine believes that qi deficiency in the human body has not been fully exercised, and substances that cannot be gasified are converted into fat, that is, qi deficiency is fat. People with qi deficiency are equivalent to lack of kinetic energy to slow down body turnover, and excess energy is converted into fat accumulation under the skin, which leads to obesity. Western medicine explains that human metabolism is slower than ordinary people.

The reason of blood deficiency in TCM is that people can't make ends meet, that is, the nutrition is insufficient or high, and there is fire in the body, that is, the energy consumption in the body is high and the turnover speed is fast, so that the external circulation nutrition is wasted after being used. Western medicine explained that this person's metabolism is too strong, resulting in consumption greater than intake.

When qi deficiency occurs in the body, it is necessary to replenish qi. How to choose the medicine for invigorating qi?
