What does "San Jiao" refer to?

The triple energizer (San Jiao) refers to the upper, middle, and lower jiao. A detailed explanation is as follows:

The concept of San Jiao is unique to Traditional Chinese Medicine (TCM) and describes an internal system responsible for the movement and regulation of qi (vital energy) in the body. The upper jiao is located in the thoracic cavity and includes organs such as the heart, lungs, trachea, and throat. Its primary function is regulating respiration and the flow of qi. The middle jiao is situated in the abdominal region and encompasses the stomach and spleen. It mainly governs digestion and absorption of food, transforming nutrients to nourish the entire body. The lower jiao resides in the pelvic cavity and includes organs such as the liver, bladder, and reproductive organs. Its main functions involve excreting waste products and regulating the reproductive system.

According to TCM, maintaining balance among the three jiaos is essential for overall health. This balance can be supported through diet, exercise, massage, and other methods. For example, consuming easily digestible foods and engaging in moderate physical activity can aid digestion and absorption in the middle jiao. Breathing exercises and emotional regulation help maintain equilibrium in the upper jiao. Healthy daily routines and regular elimination habits contribute to the well-being of the lower jiao. If physical discomfort or symptoms arise in daily life, it is recommended to seek medical attention at a hospital, undergo appropriate examinations, and receive treatment based on the underlying cause.
