This course provides the foundational knowledge for the understanding of Chinese Medical theories, where they fit in the bigger picture of traditional Chinese models of the natural world, and how they are applicable to the human condition. Continuing from the first semester we will learn the causes of diseas, the basics of diagnosis including pulse and tongue diagnosis. We will explore the channel systems that are laid out in the historical, classic text, Huang Di Nei Jing Ling Shu. In modern times the emphasis has been on the Primary Channels, also called the Principal Channels. We will go further and study the Sinew (Tendono-Muscular) channels, the Luo Mai (Linking Vessels), the Jing-Bie (Channel Divergences) and the 8 Curious/Extraordinary Vessels.
