What is the normal direction of Qi flow in TCM?

In Traditional Chinese Medicine (TCM), the normal direction of Qi flow is indeed downward, primarily associated with the functions of the organs and the balance of the body's energy systems. This downward movement is critical for several physiological processes, such as digestion and elimination. For example, the spleen is responsible for transforming and transporting food and fluids, and its Qi flow moves downward to aid the intestines in the absorption and elimination processes.

Additionally, this downward flow is essential in maintaining the balance of Yin and Yang in the body. When Qi flows downward efficiently, it supports the kidneys, which are fundamental to the health of the entire body and are often viewed as the root of Yin, providing a stabilizing force against excessive Yang.

While upward, sideways, and outward movements of Qi are also recognized within TCM, they are typically associated with specific functions or conditions rather than representing the foundational norm of Qi flow. Upward movement might correspond to conditions like the upward movement of Yang or the action of certain herbs, while the sideways and outward movements are more about energy dispersal or pathologies rather than the natural, balanced state of Qi.
