Basic theory of traditional Chinese medicine: physiological characteristics of five zang-organs and spleen

1. Spleen likes dryness and hates dampness: the spleen and stomach belong to the soil in the five elements, but according to the theory of yin and yang, the spleen is yin soil and the stomach is yang soil. Yang of the spleen tends to decline, while Yin tends to flourish. Spleen also governs the transport and transformation of body fluids, so dampness invades the human body, which is most likely to hurt spleen yang. Yang Can with spleen deficiency not only leads to stagnation of dampness in the body, but also easily leads to invasion of external dampness. For example, "Clinical Guide to Medical Records" said: "Those who are wet and happy to return to the spleen feel the same qi." So the spleen "likes dryness and hates dampness".

The theory that spleen likes dryness and hates dampness has certain clinical significance.

2. Spleen is the hub of Qi-Qi: the spleen is located in the middle focus of the human body, with heart and lung above and liver and kidney below. Therefore, the ascending and descending movements of fire and water, qi and blood, yin and yang of the human body are all centered on the spleen. The collection of the examination website, such as "On Blood Syndrome", says: "Its qi is connected with the heart and lungs, the liver and kidney, and it fills all directions and tendons. The so-called people who live in the center and are smooth on all sides. " Therefore, the obstruction of qi movement in human body is most likely to lead to imbalance of spleen and stomach, abnormal transport and transformation, loss of appetite, nausea and vomiting, abdominal distension, and loose stool. The main points of treatment are regulating qi and regulating spleen and stomach.

In addition, spleen-qi governing ascending is also one of the characteristics of spleen, which has been discussed in Spleen Governing Ascending Qing.

3. Spleen corresponds to long summer: Chinese medicine believes that the five internal organs correspond to the four seasons of yin and yang in nature. Spleen is too wet and dirty soil, and it should be wet in the long summer, so the temper should be in the long summer. Because of the seasonal dampness in long summer, the spleen likes dryness and hates dampness, so dampness is easy to invade the spleen, leading to abnormal transport. Therefore, in the long summer, fragrant products such as Pogostemon, Eupatorium odoratum, etc. Often added.
