The Triple Heater Channel (San Jiao) is also known as the Triple Burner Channel or the Triple Warmer Channel. It is named for the three “heaters” (burners or warmers) of the body. The Upper Heater includes the functions of the Lungs and Heart.
On a physical level, The Triple Warmer meridian is responsible for circulating qi (energy), blood, fluids, and hormones throughout the body. Here we use the channel to help circulation and movement.
But the Triple Warmer channel is also extremely helpful in our social and emotional relationships. Its like the host of a party, who is making sure everyone has what they need, are comfortable with one another, and are having a fantastic time.
