Heart (HT)
手少阴心经 · Shou Shaoyin Xin Jing
Overview
The Heart meridian, with only 9 points, is the shortest of all primary meridians, yet it holds the highest position in the organ hierarchy. The Heart is so revered in Chinese medicine that classical texts insist it must never be directly assaulted by pathogenic factors -- the Pericardium exists specifically to shield the Emperor from attack. When we say someone has 'Heart Fire' or 'Heart Blood deficiency,' we are describing patterns that affect the most essential aspect of the person's being.
The meridian's peak time of 11 AM to 1 PM (the Noon hour) corresponds to the maximum Yang point of the day, when the sun is directly overhead and Fire energy is at its apex. This is traditionally considered the best time for social interaction, joyful activity, and taking the midday meal. The Chinese practice of the afternoon rest (wu xiu) after this peak reflects the natural turning from maximum Yang toward the beginning of the Yin phase.
HT-7 (Shen Men, Spirit Gate) is one of the most frequently used points in modern clinical practice, particularly for the epidemic of anxiety and insomnia that characterizes contemporary life. Its very name -- Spirit Gate -- indicates its function: it is the doorway through which the Shen enters and exits, and stimulating this point helps settle the spirit back into its residence in the Heart. For chronic insomnia, pressing HT-7 for two minutes on each wrist before bed can produce noticeable improvement within days.
Pathway
The Heart meridian originates within the heart organ, emerges through the surrounding blood vessels, descends through the diaphragm to connect with the small intestine. An ascending branch rises from the heart alongside the esophagus to the throat, then ascends to connect with the tissue surrounding the eye. The principal branch crosses from the heart to the lung, emerges in the axilla (HT-1, Ji Quan), descends along the medial aspect of the upper arm on the posterior border of the biceps, passes through the medial elbow, continues down the anteromedial forearm along the ulnar side, crosses the wrist at HT-7 (Shen Men), traverses the palm, and terminates at the radial side of the little fingertip (HT-9, Shao Chong).
Functions
The Heart meridian governs blood circulation, houses the Shen (spirit-mind), and controls consciousness, cognition, and emotional equilibrium. The Heart dominates the blood vessels, and its health is reflected in the complexion. It opens to the tongue, governing speech and taste. The Heart's fire provides the warmth that sustains all physiological processes and the light of awareness that enables clear perception. It maintains the connection between the physical body and the spiritual essence of the person.
Related Organ
Heart (Xin) -- the 'Emperor' of the organ system, housing the Shen and governing blood circulation. The Heart must never be directly attacked by pathogens; the Pericardium serves as its protective shield. All other organs serve the Heart, and when the Heart is disturbed, the entire being is affected.
Related Emotion
Joy (Xi), but in the pathological sense of overexcitement, mania, or scattered elation. Balanced Heart function produces warmth, contentment, and appropriate emotional expression. Deficiency leads to joylessness, emotional flatness, and disconnection.
