BL-07 (Tong Tian) Celestial Connection

What does BL-07 Tong Tian do?

BL-07 benefits and regulates the nose, and clears the head — and it is the only point in the scalp run whose recorded action names the nose FIRST. Where its neighbours lead with wind and the head, this one leads with the nose, and its indication list follows suit.

• Benefits and regulates the nose — recorded first, and the point’s distinguishing feature
• Clears the head

A name trap worth clearing up immediately. “Tong Tian” means Celestial Connection — tian is heaven — and it would be reasonable to assume that makes BL-07 one of the classical Window of Heaven points. It does not. Querying our own category fields returns ten Window of Heaven points — BL-10 Tian Zhu, DU-16 Feng Fu, LI-18 Fu Tu, LU-03 Tian Fu, P-01 Tian Chi, REN-22 Tian Tu, SI-16 Tian Chuang, SI-17 Tian Rong, SJ-16 Tian You and ST-09 Ren Ying — and BL-07 is not among them. Several of those names contain tian too, which is exactly why the assumption is easy to make. The Bladder channel’s Window of Heaven point is BL-10, three positions further along.

What the name does mean. BL-07 sits 4 cun inside the hairline, near the crown — the highest ground the Bladder channel crosses, and close to DU-20 Bai Hui at the vertex. Connecting to heaven reads as a description of that elevation. It is a positional name that has been mistaken for a classificatory one.

The scalp run. BL-03 through BL-09 are seven points in a line whose actions and indications overlap heavily, all recorded with the same subcutaneous 0.3–0.5 inch insertion. This library discloses that overlap on every one of their records rather than inventing distinctions between them.

What is BL-07 Tong Tian used for?

BL-07 is used for headache and giddiness, and for nasal obstruction, nosebleed and runny nose. Our own indication record is reproduced here in full — five entries, the longest list in the scalp run.

• Headache
• Giddiness
• Nasal obstruction
• Epistaxis (nosebleed)
• Rhinorrhea (runny nose)

Three of the five are nasal, and that is what distinguishes this point. Comparing all seven scalp records, BL-07 is the only one carrying rhinorrhea, and one of only two carrying nosebleed (the other is BL-04). Obstruction, bleeding and discharge together make this the most complete nasal group in the run — consistent with its recorded action naming the nose first.

An honest note. A nosebleed that will not stop, or one that is heavy or recurrent, needs medical care. Persistent nasal obstruction or one-sided discharge warrants assessment rather than repeated self-treatment. Sudden severe headache requires urgent assessment. This record documents classical use and should not delay any of that.

Why the Bladder channel is a nose channel at all. It begins at BL-01 Jing Ming at the inner corner of the eye, immediately beside the nose, and nasal indications recur along its whole length — our BL-66 record carries a nosebleed indication on the little toe. The scalp points are simply the stretch nearest the nose.

How it is combined. With BL-06 in front and BL-08 behind on the same line. With LI-20 Ying Xiang beside the nostril — the principal nose point — and Yin Tang between the brows. With DU-23 Shang Xing and DU-20 Bai Hui on the midline. With LI-04 He Gu distally. All held here.

Where is BL-07 Tong Tian located?

BL-07 is on the top of the head, 4 cun inside the hairline on the 1.5-cun lateral line — one and a half cun behind BL-06, and the highest point of the Bladder scalp run.

• 4 cun inside the anterior hairline, 1.5 cun lateral to the midline
• 1.5 cun behind BL-06 Cheng Guang; BL-08 Luo Que lies 1.5 cun further back
• DU-20 Bai Hui sits on the midline in this region, at the vertex

Even spacing, and a landmark to check it against. From BL-05 onward the run steps back in equal 1.5-cun intervals, so BL-07 is the third of four evenly spaced points. Unlike most of the run it also has an independent reference nearby: DU-20 at the crown, which can be found from the ear apexes rather than from the hairline. Cross-checking a chain measurement against a landmark located a different way is the practical value of this position.

The 1.5-cun lateral line is established at BL-04, whose record defines it proportionally as one third of the DU-24 to ST-08 distance.

The hairline problem. These points are measured from the anterior hairline; a receded or asymmetrical hairline removes the reference, and the classical solution takes anterior to posterior hairline as 12 cun. Our BL-03 record sets that out in full. At 4 cun in, BL-07 is a third of the way along that span — far enough back that the proportional method matters more than the hairline itself.

On the name. “Tong Tian” — Celestial Connection, or Reaching Heaven. Positional, describing the elevation, and not a Window of Heaven designation despite the shared character.

How is BL-07 Tong Tian needled?

The standard texts record SUBCUTANEOUS insertion — the needle laid along under the skin — to roughly 0.3–0.5 inch, with moxibustion applicable. What follows is a neutral record of what the reference literature documents, not instruction for a reader.

• Angle and depth as recorded: subcutaneous (transverse), 0.3–0.5 inch — the same insertion recorded at every point in the BL-03 to BL-09 run.
• Moxibustion: recorded as applicable here. Our records state it at BL-04, BL-05, BL-07 and BL-09 but not at BL-03, BL-06 or BL-08; nothing is asserted about why.
• Regional anatomy: the epicranial aponeurosis lies beneath thin skin; branches of the superficial temporal and occipital vessels and nerves run in the region; the parietal bone lies directly beneath.

Why subcutaneous, and why that is the whole safety story. There is bone immediately under the scalp, so the transverse angle is the only insertion the anatomy permits. This is a low-hazard point in that specific sense: no cavity, no organ, no major vessel. The scalp is richly vascular and bleeds readily — a nuisance rather than a danger.

One qualification that belongs on the vertex region. Our DU-20 record notes the standard caution regarding the anterior fontanelle in infants, where the skull is not yet closed. That caution attaches to the midline vertex in the very young; BL-07 sits lateral to it, and our own record carries no such statement. It is mentioned here because a reader working across the crown should know where the caution lives rather than assume it applies everywhere or nowhere.

What is not claimed. No study measuring a safe depth at BL-07 could be located, and none is borrowed. No case report naming BL-07 was located.

Is there research on BL-07, and what should a reader know?

No trial isolates BL-07. Where the point appears it is one component of a rhinitis or headache protocol, and a study that includes a point in a protocol is not evidence about that point.

Allergic rhinitis is where a reader is most likely to meet claims near this point, since it has a substantial acupuncture trial literature. Those protocols are built around LI-20 Ying Xiang, Yin Tang and LI-04 He Gu, with scalp points appearing as supplementary at most. Evidence about a protocol is not evidence about a supplementary point within it.

What this page can state with confidence. BL-07 has the longest indication list in the scalp run and the fullest nasal group — obstruction, bleeding and discharge — and it is the only one of the seven recording rhinorrhea. Its recorded action names the nose first, which no other point in the run does. And its name contains tian but it is not a Window of Heaven point; that set is BL-10, DU-16, LI-18, LU-03, P-01, REN-22, SI-16, SI-17, SJ-16 and ST-09, verified against our own records.

A note on searching for it. “BL 7”, “UB 7” and “Tongtian” searches return protocol trials and a large volume of unrelated material — Tongtian is a common element in place names, temple names and fiction. Our library codes this channel BL- while some sources use UB-. Any claim attached to this point should be checked against what a study actually used.
