What organ corresponds to the time frame of 11pm to 1am?

The correct answer is the Gallbladder, which corresponds to the time frame of 11pm to 1am in Traditional Chinese Medicine (TCM). According to the TCM clock, each organ has a two-hour period during which it is most active and is believed to work on the body's energy or Qi during that time.

The Gallbladder's function in TCM involves the storage and secretion of bile, which plays a crucial role in digestion and in the regulation of emotions, particularly decision-making and the ability to take action. During the hours of 11pm to 1am, the body is typically in a state of rest and recuperation, which is also a time for the gallbladder to process and prepare the bile necessary for digestion during waking hours.

This understanding reflects the holistic view of TCM, where organ function is associated with specific times of day, thereby emphasizing when certain organs should be nurtured or supported, particularly through lifestyle choices and treatment modalities like acupuncture.
