Adapting itself to obstacles and bending around them, wood in the earth grows upward without haste and without rest. Thus too the superior man is devoted in character and never pauses in progress.
- The I Ching
Known as the wood element in Chinese Medicine the main function of the liver is to ensure the smooth flow of Qi. It has no part in the actual production/formation of Qi thus liver Qi can never be in a state of deficiency, only stagnation. The liver has a strong influence throughout the body so if this flow stagnates, many issues can arise. The liver also stores blood. When the body moves blood circulates in the channels, when at rest, it flows back to the liver. This is where the liver can become deficient.
The liver is a yin organ, opens to the eyes (brings luster), governs the tendons (promotes elasticity) and reflects in the nails (gives strength and moistens). It is most active between 1am-3am and when there is a problem, many people complain about waking up during that time of night. The Hun (Ethereal soul) is housed by the liver. This is the mental-spiritual aspect of the liver. It influences ones capacity for making plans and finding direction in life. When lack of direction or mental confusion is present it is said the Ethereal soul is not grounded. At night before falling asleep one may also feel as if they are "floating" or have a vague feeling of fear. Many emotions are associated with the organs of the body; anger and irritability are connected to the liver.

Diet and eating habits can affect the liver. Heavy, greasy foods and "hot" foods can lead to excess fire in the liver. These foods include; lamb, beef, curries, spices and alcohol. A lack of consumption of warming foods such as certain meats and grains can lead to liver blood deficiency. Sour foods, in moderation, are beneficial for the health of the liver. Too much sour can cause an imbalance. Skipping meals and eating on the run can hinder the health of the liver. Those with weak liver energies should sit down and slowly eat their meals because eating on the run can strain the digestive system and contribute to stress, which overburdens the liver.
Regular exercise- for twenty to thirty minutes every day- is equally important for both excess and deficient liver syndromes. Exercises such as swimming, yoga, tai chi, running and mountain biking will be of great benefit for a healthier liver. If a person is stressed out or tires easily, tai chi and yoga would be the best exercise for them. Those who have lots of energy to "burn" would highly benefit from the more intense type work-outs.
