The Yellow Emperor (2497 - 2398 BCE) is the legendary inventor of Chinese medicine. In his classic work the Huangdi Neijing (Yellow Emperor’s Inner Canon) various principles, such as yin and yang, qi, and the wuxing, compose the Universe. The work was one of the first medical treatise to stress the integration of both spiritual and physical treatments as a holistic approach to medical treatment.
The Huangdi Neijing is actually two texts. The first text is the Suwen, (Basic Questions) and covers the theoretical foundation of Chinese medicine and its diagnostic methods. The Suwen includes topics on feng shui, qigong, acupuncture, herbal medicine, fortune telling, meteorology, and astrology. Because of this vast amount of information, it is a major text of Daoism. The second text named Lingshu (Spiritual Pivot) shares the practical elements of acupuncture therapy.
