The intersection of heart and kidney-also known as the pole of heart and kidney and the pole of fire and water-is a summary of the relationship between yin and yang and fire and water in the physiological state of heart and kidney. Its specific meaning means that the heart yang is lower than the kidney, so as to nourish the kidney yang, restrain the kidney yin and make the kidney Shui Han; Kidney yin helps the heart to nourish the heart yin, inhibits the heart yang, and makes the heart fire not prosperous.
As the embodiment of the normal relationship between heart and kidney, the intersection of heart and kidney occupies an important position in the theory of traditional Chinese medicine and has extensive guiding significance in clinic. However, there is not much discussion on it in undergraduate textbooks, especially on its historical origin, pathogenesis, syndrome differentiation and treatment. Therefore, based on the experience of other teachers, this paper further combs and discusses the theory of heart-kidney intersection.
Physiological mechanism of heart-kidney intersection;
The intersection of heart and kidney is a reflection of the normal relationship between heart and kidney.
The heart, the official of the monarch, is the sun in the sun, a dirty fire; The kidney is a strong official, living in the lower jiao, yin in the middle, and dirty water. Shang Shu Hong Fan said, "Fire is on fire and water is on water." Fire is on water, and water and fire are separated.
Therefore, in Zhouyi, it belongs to useless divination, while between heart and kidney, it is said to be auspicious. So what is the force that makes the kidney yang rise and the heart yang dive, reaching the state where the heart and kidney intersect?
Pathology and treatment of heart-kidney disharmony;
Disharmony between heart and kidney is a summary of the pathogenesis of imbalance between yin and yang of heart and kidney. Some scholars divide heart-kidney disharmony into three types: heart-kidney disharmony, kidney disharmony and heart-kidney disharmony.
Heart-kidney disharmony caused by heart yin-yang imbalance is called heart-kidney disharmony type; The disharmony between heart and kidney caused by the imbalance of yin and yang of kidney is called disharmony between heart and kidney; The disharmony between heart and kidney is called disharmony between heart and kidney, which is caused by the disharmony between yin and yang.
"On Su Wen and Forbidden Needle" says: "The liver is born on the left and the lung is hidden on the right". The liver rises from the left and the lungs descend from the right, which controls the left and right qi movement of the human body and the liver controls the release of qi. It is the main pipe of Qi, and the ups and downs of Yin and Yang between heart and kidney are also a part of human Qi.
Therefore, the normal intersection of heart and kidney also depends on the regulation of liver and lung qi. When liver qi rises, it can raise kidney water to the heart, while when lung qi falls, it can lower heart fire to the kidney.
