The Governor's own back point. Dushu (BL-16) is the Back-Shu point of the Du Mai — the great Yang governing vessel — and it holds a quiet but important role in regulating the heart and chest, calming rebellious Qi and supporting the Yang of the entire back.
Name & story
The name 督俞 Dushu breaks into two characters: 督 (Dū) means "to govern" or "to supervise" — and it refers directly to the Du Mai, the Governing Vessel, the great Yang channel that runs up the midline of the back like a spine of energy. 俞 (Shū) means "transport" or "infusion point". So Dushu is simply "the transport point of the Governing Vessel" — the place on the back where the Qi of the Du Mai pours outward into the Bladder channel, like a tributary branching from a great river. It is the one point on the Bladder Meridian (BL) that directly reflects and nourishes the Du Mai itself.
Point family & character
Dushu (BL-16) belongs to the Bladder Meridian (BL). It is the Back-Shu (Back-Transporting) point of the Du Mai — the Governing Vessel. Like all the Back-Shu points along the inner Bladder line, it acts as a direct window into its associated channel, reflecting and influencing the state of the Du Mai and the organs of the chest.
Five-element dynamics
The Du Mai is the sea of all Yang channels — it governs and unites the Yang Qi of the entire body, rising up the spine and over the head. BL-16 sits at the level of the sixth thoracic vertebra (T6), in the middle of the upper back, right in the territory of the heart and chest. When the Qi of the Du Mai is disturbed — or when the heart and chest are tight, painful or in turmoil — this point offers a direct point of entry to restore flow and calm.
Location
Find the lower edge of the spinous process of the sixth thoracic vertebra (T6) and measure 1.5 Cun lateral to it, on either side of the spine. It sits between BL-15 (Xinshu, at T5) above and BL-17 (Geshu, at T7) below — roughly in the middle of the upper back, at the level of the heart.
Anatomy & fascia
The point lies in the upper back, between the trapezius and the deeper spinal musculature, over the thoracic spine.
Needling
The needle is inserted at an oblique angle, directed slightly toward the spine. As with all Back-Shu points in the thoracic region, care is taken not to needle too deeply, as the chest cavity lies beneath.
Safe depth
The golden tip
Because BL-16 sits in the middle of the upper back, it is not easy to press yourself — but a partner can apply gentle, firm thumb pressure or warm massage to the area 1.5 Cun either side of the spine, at the level between the shoulder blades, slightly below their midpoint. A warm pack or heat pad applied to the upper back over this area can be soothing for chest tightness, cold sensations in the back, or general upper-back stiffness.
