The role of the heart (xin), known in traditional Chinese physiology as the ruler of the other organs, has exceptional importance. Its function in traditional Chinese medicine parallels its Western anatomic function of pumping blood throughout the body to maintain life, but in the Eastern tradition it is also intimately involved with mental and emotional processes.
Considered the residence of the mind and spirit, the heart is the organ most often involved in psychological imbalances. Properly nourished and balanced, the heart maintains our innate wisdom, contentment, and emotional balance. Symptoms of heart imbalance include palpitations, shortness of breath, sweating easily, mental restlessness, Insomnia, forgetfulness, chest pain, tongue pain, and burning urine.
