Chinese medicine is one of the oldest medical practices in the world and has existed for at least twenty-three centuries. Although Chinese medical practices are nearly ancient, some of these approaches are still being used today. Philosophy plays a big role within the field of Chinese medicine in understanding how the health of the human body works. Chinese medicine is based on the principles of Yin and Yang; the Yin-Yang relationship describes everything in the universe as connected and complementary to each other. A balance of the two is believed to result in good health.
