As a bodyworker, I nickname San Jiao the traveller's meridian, helping us adapt to changing altitudes, different time and climate zones. And adapt to the changes prompted by Menopause and Andropause. It's also the body's thermostat. Buddy of the immune system. Chief movement navigator of fluids around the body.
