Heart Meridian
Houses the mind (神). The heart is the "ruler" of the organ system in TCM theory.
Pathway
The Heart meridian begins in the heart and emerges at the axilla at HT-1 Jiquan. It runs along the medial (inner) side of the upper arm, crosses the elbow at HT-3 Shaohai, continues down the medial forearm to the wrist at HT-7 Shenmen, and ends at the radial side of the little finger at HT-9 Shaochong.
Internally, a branch connects the heart with the small intestine; another rises along the throat to the eye. With only nine points, the channel is short but traditionally considered central to the whole system.
Role in TCM theory
- Housing the mind (心主神明) — The heart is said to house the shen (神), the aspect of consciousness expressed in thought, sleep, and emotional clarity.
- Ruling the blood and vessels (主血脈) — The heart is described as driving blood through the vessels; its state is read in the complexion, tongue, and pulse.
- The sovereign ruler (君主之官) — Chapter 8 of the Suwen calls the heart the sovereign on whose clarity the other organs depend.
- Fire pair with the Small Intestine — Heart and small intestine share the Fire element and are described as interior–exterior partners.
Common acupoints on the Heart meridian
| Point | Name | Location | Traditional use |
|---|---|---|---|
| HT-3 | Shaohai (少海) | At the medial end of the elbow crease, anterior to the medial epicondyle | The he-sea point; traditionally associated with calming and with the elbow |
| HT-7 | Shenmen (神門) | At the ulnar end of the wrist crease, in the depression radial to the flexor carpi ulnaris tendon | The shu-stream and yuan-source point; the "spirit gate", traditionally used for restlessness and poor sleep |
| HT-9 | Shaochong (少沖) | At the radial side of the little fingertip | The jing-well point; classically used for clearing heat and reviving alertness |
Point locations follow the WHO Standard Acupuncture Nomenclature (1991). Gentle acupressure is generally considered low-risk; needling must only be performed by a licensed practitioner.
The 11 am–1 pm window
11 am–1 pm is the heart's peak. Traditional advice favors a moderate lunch and a short rest, avoiding intense exertion at midday. The saying that "the heart rests at noon" is a cultural rhythm, not a medical rule.
How this is viewed today
HT-7 has been examined in small trials for insomnia and anxiety, with preliminary results. Chest pain, palpitations, or breathlessness should always be evaluated medically; acupressure is not a substitute for cardiac care.
