Excerpt:
Traditional Chinese Medicine (TCM) is a system of healing based upon the Chinese philosophy of the correspondence between Nature (Tao) and human beings. The principle of microcosm-macrocosm is based upon the observation of several thousand years that Nature has a vital effect upon the health of people. Another fundamental principle is that of Yin and Yang, the two basic complementary energies of Nature. All of the manifestations of nature are thought to be composed of a specific balance of these two forces. Health is also thought to be due to the appropriate balance of yin and yang in the body.
