Classical Chinese medicine of the Huangdi Neijing (黃帝內經) follows a principled and patterned methodology of clinical strategies. This presentation will focus on one of the key themes of Neijing medicine: direction, a concept deep within the classical cultural understanding of seasonal law (Shize 時則) . Here we will discuss the importance of differentiating various tissue terrains, vessels (Mai 脈) and channels (Jing 經) while pairing that differentiation with appropriate level based needling from the Lingshu Guanzhen (namely the Five Directional techniques). These concepts will support the primary and secondary regions of disease manifestation, the concepts of Shun (順), Ni (逆), Shen (神), and Ji (機) in classical acupuncture, and both tool and technique of choice in the clinic. This short talk on directional medicine within the Neijing offers viewers the ability to look at certain aspects of how we may approach broad clinical strategies in our practice through the understanding of directional impairment and correspondence. This talk is NOT an introduction to Neijing medicine, it is an overview of directional medicine within the Neijing.
