What organ is most active between 7pm-9pm?

The organ that is most active between 7 PM and 9 PM is the Kidney. In Traditional Chinese Medicine (TCM), each organ is associated with a specific time of day when it is believed to be at its peak function. The Kidney is responsible for various essential functions, including storage of vital essence (jing), regulation of fluids, and maintenance of water metabolism.

During the time frame of 7 PM to 9 PM, the body's energy and activity cycle aligns with the Kidney's role. This is often seen as a time for reflection and winding down, which correlates with the Kidney’s association with deep rest and restoration after a day’s activity. It is believed that one should focus on relaxation and conserving energy during this time to support the Kidney's function.

Understanding this timing can enhance practices such as acupuncture and herbal medicine when targeting issues related to the Kidney, as interventions can be more effective when aligned with the organ's natural rhythms.
