How are the concepts of Qi and yin and yang applied in TCM?
TCM provides guidelines for both the practitioner and patient on how to best facilitate harmony between yin and yang in any set of circumstances and how to create and circulate an abundance of Qi to sustain health and well-being. These are the “stems” of TCM that spring from the root concepts of Qi and yin and yang. To assist the practitioner and patient in this task, TCM offers several different perspectives on the dynamics of Qi and the interplay of yin and yang. These different perspectives are like different types of maps of the same territory.
