Exuberant Liver Fire does not fall under the category of Yin or Yang deficiency, but further development of Exuberant Liver Fire may cause Yin deficiency. Exuberant Liver Fire is a solid heat condition caused by excessive fire-heat, upward disturbance of the liver, resulting in head swelling and pain, dizziness, eye swelling and pain, irritability, heartburn and insomnia, short and red urine (small amount of urine, dark yellow color), and constipation, whereas Yin Deficiency or Yang Deficiency is caused by insufficient yin or yang qi in the human body, which are fundamentally different from each other. Further development of Exuberant Liver Fire often burns the yin fluid and may lead to yin deficiency. When symptoms of Exuberant Liver Fire appear, one should seek medical advice from a Chinese medicine practitioner for systematic treatment. Individuals should not make diagnosis or use medication on their own, as this may lead to adverse reactions.
