In Chinese Medicine the Liver is like the Prime Minister that coordinates all the activities and organs of your body, something like the orchestra conductor. To do this the Liver has many jobs: it filters, detoxifies, stores blood, and regulates blood volume.
The Liver is responsible for planning, and it oversees our true path in life. The Liver Meridian rules the season of Spring, Rising Emotions, New Projects. The Liver relates to passionate emotions and generates anger as a clearing force to keep things moving and flowing. When anger dissolves, this passionate energy transforms into balanced faith, optimism, and wisdom.
The Liver is responsible for spreading Qi smoothly via the blood, to body, organs, and psyche. It controls the sinews and muscle tone. The Liver rules the health of nails, vision, and the eyes. Liver stagnation or hyper-activity can lead to extreme emotional states. A healthy Liver transforms potentially repressed emotions into true, reliable feelings.
The Liver’s Emotion is Anger
The Liver is easily influenced by anger, frustration, and resentment. This is useful when we want to clear away something that disturbs us. Having strong emotions is perfectly healthy, however when we fixate or make a habit of any emotion, it will bring disharmony and disease. We can utilize the clearing energy of anger by directing it into positive intentions and actions, such as new 
creative projects, or making changes in the world with balance and wisdom. Excessive anger and resentment cause the Qi in the body to rise up too quickly, causing headaches, ringing in the ears, high blood pressure, or GERD. If the Qi stagnates it can lead to abdominal distention, more frustration, slow digestion and more. A good rule of thumb is to never eat when you are angry or upset. And do not eat with people you do not like.
The Liver is associated with the Wood element and the Spring season.
That’s because Spring brings a buzzing of excitement in the air and in our bodies. In the spring the energy is rising up and outward in powerful surges. It’s a time of enormous change and growth, especially underneath the surface. Hence the Wood element is associated with new ideas, inspiration, and nurturing new projects. In the Spring our energy moves up and outward. We want to move more, we have more energy within us and we want to do something with it.
The SOURCE Point of the Liver Meridian is LV-3, Taichong on the top of the foot. A meridian source point is the point that most closely exemplifies the function of the entire meridian. Find LV-3 by tracing the two tendons of the big toe and second toe upwards a few inches. L-3 is in a hollow just before the arch bone. Press this point to balance emotions, calm anger, detox, and clear blood stagnation.

Trace the Liver Meridian to Balance:
Set a clear intention to build health. Start at the LV-1 point, on the inside of the big toe. Trace up the inside of the leg to the groin seam, around the genitals, back to the floating ribs, forward to finish at the lowest corner point of the ribs at LV-14. (You may optionally trace the internal pathway that continues up the front midline to the chin, up the sides of the face to the center of the eyes, eyebrows, and up the center forehead to GV-20 at the top of the head.) Do both sides at the same time, or one after the other.
To Clear the Liver Meridian:
Set a clear intention to build health. Trace the meridian backwards once, starting at GV-20 at the top of the head, down to the inside of the big toe. Do both sides together or one at a time. Then trace forward 3 times as above, both sides at the same time or one after the other.
“When the liver is harmonious, there is never stress or tension. People with vital livers are calm. They have unerring judgment, naturally effective as leaders and decision-makers.”
