The heart is the master of the body. According to the theory of traditional Chinese medicine, the "heart" not only controls the circulation of blood but also manages mental activities, making it the most important organ in the human body, referred to as the "sovereign" organ. Therefore, maintaining health must start with nurturing the heart, as a strong and healthy heart is the foundation for the overall health and normal functioning of all the internal organs. If the heart is not in a normal state, leading to blockages and poor blood circulation, it will affect the various organs and cause damage, thus failing to achieve the goal of health preservation and longevity.
