The physiological functions of the liver are to store blood, to drain, and to open the orifices of the eyes. The liver is a body of yin and uses yang. Therefore, the common symptoms of liver lesions include liver qi stagnation, liver fire, liver wind, etc.; if liver blood is insufficient, liver yin is deficient, essence does not turn into blood, and the liver loses moistening, the deficiency of liver blood or liver yin will occur.

The main symptoms of liver yin deficiency are headache and dizziness, hidden pain in both dermatomes, tinnitus and insomnia, heartburn and heat, dryness of the mouth and throat, night sweating, red tongue with little moss, and fine pulse. Due to the deficiency of liver yin can't control the yang, the deficiency of yang is over-exuberant, up to disturb the clear orifices, so see headache and dizziness, tinnitus and insomnia, etc.; Yin deficiency meridians are not nourished, so the wounds are hidden pain; Yin deficiency and internal heat, so see the five heart and heat, dryness of the mouth and throat, night sweating, etc.; Tongue with red and little moss, pulse is fine and countless, are all the yin deficiency and over-exuberance of yang symptoms.

What are the symptoms of liver deficiency?

Liver deficiency can be categorized into liver yin deficiency and liver yang deficiency, both of which have different symptoms, with liver yin deficiency being the most common.

Liver deficiency is generally defaulted to liver yin deficiency. When liver yin is deficient, emotional disorders, qi stagnation and fire, it is easy to appear hot flashes and night sweats, dizziness, tinnitus, dryness and astringency of the eyes, heartburn and heat, vision loss, insomnia and night sweats, dry mouth and throat, and a glossy tongue with little moss, and other symptoms. Dizziness, tinnitus and dry eyes are common symptoms of liver yin deficiency.

Modern medical practitioners believe that yang deficiency can also occur in the liver, which is due to the deficiency of yang qi in the liver, resulting in yin-cold internalization and phase-fire internalization that turns into heat. Symptoms of liver yang deficiency mainly include fear of cold, coldness, warmth in the limbs, diarrhea, failure of grain digestion, mental weakness, pale tongue with white fur and teeth marks, and sunken and feeble pulse. Liver is a rigid organ and hosts phase fire. When liver yang is deficient, it is easy to develop cold and cold limbs; when yang is deficient, the intestines and stomach are unable to digest food properly and the food is discharged directly from the intestines, resulting in feces mixed with undigested food leading to unctuousness of the finished grains and diarrhea; deficiency of yang will make one tired and weak and manifests itself as sluggishness and depression; the weakening of yang will lead to the insufficient consumption of water in the body which will lead to stagnation and result in a chubby tongue with large or teeth marks.
