What is the main function of the San Jiao (SJ) in Traditional Chinese Medicine?

The main function of the San Jiao, or Triple Warmer, in Traditional Chinese Medicine (TCM) is as a channel that carries yuan source Qi throughout the body. The San Jiao is considered one of the three ‘heaters’ in TCM, playing a crucial role in the distribution and regulation of Qi and fluid metabolism across various body systems. It does not store Qi but instead oversees its movement, ensuring that it reaches all areas to maintain balance and harmony in bodily functions.

This aspect of the San Jiao allows it to influence other organ systems indirectly by promoting the proper flow of Qi, which is essential for overall health. When the distribution of yuan source Qi is effective, it supports various physiological activities, including digestion, blood flow, and emotional well-being, but those are more indirect roles influenced through the management of Qi rather than being primary functions of the San Jiao itself.
