The quiet hinge of the lower back. Xuanshu (GV-5) sits at the crossroads of the lumbar spine, steadying the flow of Yang Qi upward along the Governing Vessel — a small but reliable point for lower back pain, digestive weakness, and the kind of fatigue that comes from a cold, depleted middle.
Contraindications
GV-5 is a standard lumbar back point and is generally safe when needled to the appropriate depth and direction. As with all posterior midline points in the lumbar region, care should be taken not to exceed the recommended depth to avoid entering the spinal canal.
Name & story
The name 悬枢 Xuanshu means "Suspended Pivot" or "Hanging Hinge". Picture the spine as a great vertical axis — and at this particular vertebra, right in the lumbar region, there is a pivot, a hinge-point where the body turns and balances. The character 悬 (xuán) suggests something suspended in mid-air, held in careful balance, while 枢 (shū) is a door-hinge or axle — the thing everything else turns around. Together, the name evokes a point that keeps the lower spine moving freely, like a well-oiled hinge on a gate.
Point family & character
GV-5 belongs to the Governing Vessel (GV), the great Yang channel that runs up the spine and governs all Yang in the body. It sits on the midline of the lumbar spine, between the better-known Mingmen GV-4 (the Gate of Life-Fire below) and Jizhong GV-6 above.
Five-element dynamics
The Governing Vessel carries Yang Qi upward along the spine, and GV-5 sits right in the lumbar region — the domain of the Kidneys and the lower Burner. When the Yang of the Kidneys flags, the middle grows cold, digestion weakens, and the lower back loses its support. Xuanshu, as a pivot-point on this great Yang highway, helps restore the movement of Qi through the lumbar area and warms the intestines when they have grown sluggish from Cold or Deficiency.
Location
On the midline of the lower back, below the spinous process of the 2nd lumbar vertebra (L2). It sits between Mingmen GV-4 (below L4's spinous process) and Jizhong GV-6 (below T11's spinous process). A helpful landmark: ask the patient to find the top of the iliac crest — that level corresponds roughly to L4; GV-5 is two vertebrae above that.
Anatomy & fascia
The point lies on the posterior midline, over the interspinous ligament between the spinous processes of the second and third lumbar vertebrae.
Needling
The needle is inserted perpendicularly, or at a slight upward angle, into the interspinous space.
Safe depth
0.5–1 Cun.
The golden tip
For lower back stiffness or cold, achy lumbar discomfort, gentle warmth over this area is the simplest home support. Hold a warm pack or a moxa stick (if available) over the midline of the lower back, just below the level of L2, for several minutes. This can ease stiffness and support the Yang of the lower back. Gentle backward-bending stretches, done slowly and within comfort, also help keep the lumbar "hinge" moving freely.
