The heart is most active during the time frame of 11 am to 1 pm in the horary cycle. This period aligns with the peak energy and physiological functions of the heart according to Traditional Chinese Medicine. During this time, the fire element, which corresponds to the heart, is at its zenith, symbolizing vitality and the height of its activity level. Understanding this timing is crucial for practitioners, as it can influence treatment decisions, including when to perform certain acupuncture techniques that target heart health or emotional well-being related to the heart.

In contrast, the other options represent different organ systems and their respective peak times according to the horary cycle. For instance, the liver is most active from 1 am to 3 am, while other organs also have their designated peak periods that do not correspond with the heart's optimal functioning times. Recognizing these cycles allows practitioners to harmonize treatments effectively with the body's natural rhythms.
