During which time period is the pericardium most active in the horary cycle?

In the horary cycle, each organ in Traditional Chinese Medicine (TCM) is associated with a specific two-hour time period during which it is believed to be most active. The pericardium, which is responsible for protecting the heart and regulating its functions, is particularly active from 7 PM to 9 PM.

This time frame corresponds with the body's natural rhythms, where emotional and mental states can be particularly influenced by the heart's condition. During this period, it is thought that energy or "qi" related to the pericardium is at its peak, allowing for greater emotional regulation and protective functions of the heart. The concept of "qi" flow and its relation to time underscores the holistic principles of TCM, emphasizing the connections between the body’s functions and its circadian rhythms. Thus, understanding this cycle not only aids in treatment planning but also highlights the significance of timing in acupuncture and healing practices.
