HT-09 (Shao Chong) Lesser Surge

What does HT-09 Shao Chong do?

HT-09 is the Jing-Well and Wood point of the Heart channel — and because the Heart is a yin FIRE channel, Wood is Fire’s mother, which makes HT-09 the channel’s TONIFICATION point. It is also the Heart channel’s emergency point: the last point on the channel, at the little-finger nail, classically pricked to bleed for loss of consciousness.

• Revives consciousness — the Jing-Well function, and the reason this point appears in classical first-aid
• Clears heat and benefits the tongue, eyes and throat — the Heart’s classical relationship with the tongue
• Regulates Heart qi and calms the spirit

The Heart channel’s five-shu roles, derived from this site’s own element records rather than from a summary: HT-09 is Wood, HT-08 Shao Fu is Fire, HT-07 Shen Men is Earth, HT-04 Ling Dao is Metal, HT-03 Shao Hai is Water. The Heart is yin Fire, so:

• Tonification (mother) point — HT-09 Shao Chong (Wood, the mother of Fire) — this point
• Sedation (child) point — HT-07 Shen Men (Earth, the child of Fire)
• Horary point — HT-08 Shao Fu (Fire on a Fire channel) — not the sedation point, a common student error our HT-08 record flags
• Controlling-element point — HT-03 Shao Hai (Water, which controls Fire) — none of the three

Note that HT-07 is also the Yuan-Source point, because on yin channels the Yuan and Shu-Stream coincide. On yang channels they are separate points — a distinction set out in our BL-64 and LI-03 records.

What is HT-09 Shao Chong used for?

HT-09 is used for acute heart symptoms, for febrile disease and loss of consciousness, and for severe mental disturbance. Our own indication record is reproduced here in full.

• Palpitations
• Cardiac pain
• Pain in the chest and side (hypochondriac region)
• Mania
• Febrile disease
• Loss of consciousness

A necessary framing note. Cardiac pain and loss of consciousness are medical emergencies requiring emergency medical care. This record describes classical use and the historical role of the Jing-Well points in first-aid; it is not a suggestion that either be managed with acupuncture, and nothing here should delay calling for help. The same framing applies on the other resuscitation points in this library — DU-26 Shui Gou, Shi Xuan and LU-11 Shao Shang.

The twelve Jing-Well points share this pattern. Acute onset, collapse, fever and mental disturbance appear across the whole set, which means much of HT-09’s indication list belongs to its category rather than to the point specifically. What is distinctly HT-09’s is the Heart-channel content: palpitations, cardiac pain, and the tongue.

How it is combined. With P-09 Zhong Chong, the Pericardium’s Jing-Well point, which shares the collapse indication. With DU-26 Shui Gou, the classical revival point. With HT-07 Shen Men for the spirit. All are held here.

Where is HT-09 Shao Chong located?

HT-09 is at the thumb-side corner of the little fingernail — where a line along the radial edge of the nail meets a line across its base, about 0.1 cun from the corner. The Heart channel ends here, having run from the armpit down the inner arm.

• Radial (thumb-side) corner of the little fingernail, roughly 0.1 cun from the corner
• Located by the two-line method used for all twelve Jing-Well points
• SI-01 Shao Ze sits at the ulnar (outer) corner of the same nail — the two are on opposite corners of one fingernail, and both are held here

That pairing is the useful fact. HT-09 and SI-01 are millimetres apart on the same finger but belong to interiorly-exteriorly paired channels — Heart and Small Intestine. The same arrangement occurs on the big toe, where SP-01 Yin Bai and LIV-01 Da Dun occupy opposite corners of one nail. A prescription naming one is not interchangeable with the other.

On the name. “Shao Chong” is rendered Lesser Surge. Shao (lesser) marks the Shao Yin channel and recurs through the Heart channel’s point names — Shao Hai, Shao Fu, Shao Chong. Chong suggests surging or pouring, fitting a Jing-Well point where the channel’s qi is described as welling up.

• A Manual of Acupuncture (p. 222): On the dorsal aspect of the little finger, at the junction of lines drawn along the radial border of the nail and the base of the nail, approximately 0.1 cun from the corner of the nail.
• Chinese Acupuncture and Moxibustion (p. 166): On the radial side of the little finger, about 0.1 cun from the corner of the nail.

How is HT-09 Shao Chong needled?

The standard texts record shallow subcutaneous insertion to roughly 0.1 inch, or pricking with a three-edged needle to bleed; moxibustion is recorded as applicable. What follows is a neutral record of what the reference literature documents, not instruction for a reader.

• As recorded: subcutaneous, approximately 0.1 inch — there is almost no soft tissue at a nail corner.
• Bleeding technique: our own record documents pricking with a three-edged needle to produce a drop of blood. This is the classical method for the acute and collapse indications and is recorded here as documented practice.
• Moxibustion: recorded as applicable.
• Regional anatomy: the dorsal digital nerves and digital vessels run along the finger’s margins; the distal phalanx lies immediately beneath.

Hazard, stated proportionately. This is a low-hazard point: no cavity, no major vessel, no large nerve trunk, and a recorded depth of a tenth of an inch. Nail-corner points are notably painful — a matter of tolerability rather than danger. Where blood is drawn, the ordinary considerations of any skin puncture apply, and this record does not describe how to perform it. No study measuring a safe depth at HT-09 could be located, and none is borrowed. No case report naming HT-09 as the site of an injury was located, and none is asserted.

Is there research on HT-09, and what should a reader know?

No trial isolates HT-09. Where the point appears in modern literature it is one component of a multi-point protocol — typically for stroke, disturbance of consciousness, or cardiac symptoms — and a study that includes a point in a protocol is not evidence about that point.

Where the Heart channel’s research attention has gone. HT-07 Shen Men carries most of it, and our record for that point reports the honest result: in a trial that compared points directly, SP-06 outperformed HT-07 for insomnia. That is the closest thing this channel has to point-specific evidence, and it belongs to HT-07, not here.

A naming collision to be aware of. “Shen Men” — HT-07’s name — is also the name of a well-known auricular (ear) point in a different system, and separately overlaps in translation with REN-08 Shen Que. Our HT-07 and REN-08 records close both collisions. HT-09 has no such problem, but a reader moving between Heart-channel sources should know those traps exist.

What is reliable here. HT-09’s classification is firm and checkable against our own data: Jing-Well and Wood point, and therefore the tonification point of a yin Fire channel. That places it precisely within a system this library has now derived from first principles across fifteen channels, with every record agreeing.
