Headaches are often caused by imbalances in the internal organs, particularly the Liver, Heart, and Kidneys. In Chinese medicine, the Liver is responsible for the smooth flow of qi and Blood, and when it is not functioning properly, it can lead to headaches. The Heart, which is associated with the Shen, the spiritual aspect of the person, can also cause headaches if it is not functioning properly. Finally, the Kidneys are responsible for storing essence and providing the foundation for all of the body's activities, and imbalances in the Kidneys can also cause headaches.

Treatment for headaches in Chinese medicine often involves addressing the underlying imbalances in the internal organs and using acupuncture, herbal medicine, and other modalities to restore balance and alleviate pain.
