The San Jiao Meridian

The San Jiao Meridian (also known as the Hand Shaoyang San Jiao Meridian, 手少阳三焦经) is one of the 12 primary meridians in Traditional Chinese Medicine (TCM). It is a Yang meridian, paired with the Pericardium Meridian (Yin). Unlike other organs, the San Jiao does not refer to a physical structure; instead, it represents a functional system that regulates the body's water metabolism, Qi circulation, and temperature.

In TCM, the San Jiao is sometimes translated as the Triple Burner or Triple Warmer, describing its role in the body as a three-part functional system.

What is the San Jiao (Triple Burner)?

The San Jiao is divided into three regions, or "Burners", each regulating specific bodily functions:

1. Upper Burner (Shang Jiao)
   • Includes the Heart and Lungs.
   • Governs respiration and the distribution of Qi.
   • Often compared to a "mist" that spreads fluids and energy.
2. Middle Burner (Zhong Jiao)
   • Includes the Spleen and Stomach.
   • Responsible for digestion and nutrient absorption.
   • Functions like a "foam" that breaks down and transports nutrients.
3. Lower Burner (Xia Jiao)
   • Includes the Kidneys, Bladder, and Intestines.
   • Regulates water metabolism and excretion.
   • Functions like a "drain" that eliminates waste.

Functions of the San Jiao Meridian in TCM

The San Jiao is a vital system in maintaining homeostasis and regulating the body's energy. Its main functions include:

   • San Jiao is responsible for the transportation and elimination of fluids.
   • Imbalances may lead to fluid retention, edema, or urinary issues.
2. Distributing Qi and Blood
   • It ensures the smooth flow of Qi and Blood to the organs and tissues.
3. Balancing Body Temperature
