The Gallbladder's own back point. Danshu (BL-19) reaches directly into the Gallbladder organ, clearing Heat and Dampness, smoothing the flow of bile, and restoring the Gallbladder's role as the organ of decision and courage — when bitterness, resentment or indecision settle in the body, this is where the practitioner often turns.
Name & story
The name 胆俞 Danshu means simply "Gallbladder Shu" — the Back-Shu point of the Gallbladder. In Chinese medicine, each of the major organs has its own "transport" point on the back, a place where that organ's Qi is poured into and out of the body's surface. The character 胆 (dǎn) means both the physical gallbladder and, in a deeper sense, courage and boldness — a brave person in Chinese is someone with a "big dǎn". So this little point on the back carries a dual meaning: it tends the organ that secretes bile, and it also touches the quality of daring and resolve that the Gallbladder governs in the mind.
Point family & character
Danshu (BL-19) belongs to the Bladder Meridian (BL), which runs the full length of the back carrying all the Back-Shu points. BL-19 itself is the Back-Shu point of the Gallbladder — its most direct connection to that organ. As a Shu point, it both reflects the condition of the Gallbladder and treats it, making it indispensable whenever the Gallbladder organ is involved.
Five-element dynamics
The Gallbladder belongs to the Wood element, paired with the Liver. Where the Liver stores Blood (Xue) and plans, the Gallbladder stores and releases bile — pure and clear, it assists digestion and, on a deeper level, gives the ability to make decisions and act with resolve. When Wood becomes congested — through stress, anger, rich food or emotional holding — Heat and Dampness can brew in the Gallbladder, and bile no longer flows freely. Danshu (BL-19), sitting directly opposite the organ on the back, is the most efficient door to clear that congestion and restore the clean, smooth movement that Wood requires.
Location
On the upper back, 1.5 Cun lateral to the lower edge of the spinous process of the 10th thoracic vertebra (T10). It sits between its neighbours: Ganshu BL-18 (the Liver Shu, one level above at T9) and Pishu BL-20 (the Spleen Shu, one level below at T11).
Anatomy & fascia
The point lies in the upper back musculature, 1.5 Cun lateral to the spine, overlying the erector spinae muscle group. The chest cavity lies beneath — depth must be respected.
Needling
The needle is inserted obliquely (at an angle toward the spine), not perpendicularly. As with all thoracic Back-Shu points, the direction and depth are carefully controlled to stay safely away from the chest cavity.
The golden tip
If you feel persistent tightness or discomfort under the right ribs, a bitter taste in the mouth, or notice you feel unusually hesitant or easily startled, gentle pressure or massage along the upper-middle back — at the level of BL-19 — can be soothing. Ask a partner to apply gentle sustained pressure 1.5 Cun to either side of the spine, at the level of the lower edge of the 10th thoracic vertebra. Avoid rich, greasy food, which burdens the Gallbladder directly. Rest during the Gallbladder's own hours (11 pm–1 am) if sleep is disturbed at that time.
