Acupuncture Time Points: Chinese Body Clock and Meridian Energy Times

In Traditional Chinese Medicine (TCM), acupuncture time points often refer to the idea that each of the 12 primary meridians has a two‑hour period during the day when its energy (Qi) is at its peak. This is called the Chinese Meridian Clock or Horary Cycle. Practitioners sometimes choose acupuncture points based on this timing to harmonize the body’s energy flow.
