Yin and Yang

Repressed anger is a common cause of liver fire.
When the anger is suppressed, it is explosive, and
the heat will attack and drain the kidneys. What
exactly does that mean? If you look at it from the
Five-Element concept, the Wood element is the
liver. Wood feeds fire, the heart, and the heart
fire dries up the water or the kidneys. There is
no water to balance the fire. Patients will
experience migraine headaches, itching, not being
able to sleep, and low back and knee pain.
