Traditional Chinese medicine considers man at the center of the universe as an antenna between celestial and earthly elements. The world is a single unit resulting from one Fundamental Unit. Its movement gives rise to yin and yang which ar two antitheric aspects. When these two energies fall out of harmony, disease develops. The physician should thus take into account this concept when caring for patients and establish an energy diagnosis. Several possibilities are given at treatment which should reestablish the balance between the yin and the yang.
