Traditional Chinese medicine (TCM) is thousands of years old and has changed little over the centuries. Its basic concept is that a vital force of life, called Qi, surges through the body. Any imbalance to Qi can cause disease and illness. This imbalance is most commonly thought to be caused by an alteration in the opposite and complementary forces that make up the Qi. These are called yin and yang.
Ancient Chinese believed that humans are microcosms of the larger surrounding universe, and are interconnected with nature and subject to its forces. Balance between health and disease is a key concept. TCM treatment seeks to restore this balance through treatment specific to the individual.
It is believed that to regain balance, you must achieve the balance between the internal body organs and the external elements of earth, fire, water, wood, and metal.
