What is the colloquial meaning of "calming the liver and suppressing yang"?

The colloquial meaning of calming the liver and suppressing yang is to alleviate the symptoms of liver qi rising due to yin deficiency of the liver and kidney, where water fails to nourish wood. It is primarily a method in traditional Chinese medicine for treating liver yang hyperactivity. During treatment, heavy and sedative herbs are commonly used, and medication should be taken as prescribed by a doctor. Physiologically, the yin and yang of the human body maintain a dynamic balance. When liver yin is insufficient and yin fails to control yang, liver yang hyperactivity syndrome occurs. Liver yang hyperactivity syndrome refers to a syndrome of upper excess and lower deficiency manifested by liver yang disturbance due to yin deficiency of the liver and kidney and water failing to nourish wood. After becoming ill, it may cause discomfort such as dizziness, tinnitus, red face and eyes, insomnia with dream-disturbed sleep, soreness and weakness of the waist and knees, irritability, and impatience. It can be treated using the method of calming the liver and suppressing yang. Herbs commonly used in this treatment include oysters, raw dragon bone, concha ostreae, and lodestone, which are heavy and sedative. Additionally, Tianma Gouteng Decoction and Zhen Gan Xi Feng Decoction can be used for treatment as prescribed by a doctor, which can help improve symptoms. Treatment with calming the liver and suppressing yang should be carried out under the guidance of a doctor. If dizziness is caused by internal retention of phlegm-dampness, this method is not recommended for treatment to avoid affecting health. In daily life, it is necessary to develop good living habits and pay attention to changes in the body. If discomfort occurs, medical attention should be sought promptly. Meanwhile, attention should be paid to rest, maintaining a balanced diet, eating fresh vegetables and fruits, consuming foods that are cooler in nature, reducing intake of greasy and stimulating foods, and quitting smoking and alcohol.
