The principle of Yin Yang is the basis of Traditional Chinese Medicine.

The harmony of our Yin Yang will determine our physical and emotional health. The duality of Yin Yang, opposites and complements, is the basis of all things. The tools of Traditional Chinese Medicine aim to maintain the harmony of energy inside the body as well as between the body and the outside world. This is the "sine qua non" condition of the state of good health. Traditional Chinese medicine does not uniformly treat the symptoms experienced by a consultant: "Each person is in energy imbalance in their own way".
