A quiet but focused point on the abdomen, Shangqu (KI-17) works where the Kidney channel meets the Penetrating vessel — right in the centre of the body — to break up stubborn accumulations, ease intestinal pain and restore smooth movement through the digestive tract.
Name & story
The name 商曲 Shangqu is made of two characters: 商 (shāng), which in classical Chinese relates to the metal note in the five-note musical scale and carries a sense of something gathering or converging, and 曲 (qū), meaning a bend or curve. Together the name evokes the image of a winding, curving passage — like a bend in a river where things can collect and get stuck. This is exactly what the point treats: places where the flow in the intestines and abdomen has stalled, where matter accumulates and causes pain. The name quietly tells you what the point does.
Point family & character
Shangqu (KI-17) belongs to the Kidney channel (KI). It is a meeting point (crossing point) of the Kidney channel with the Penetrating vessel (Chong Mai) — one of the extraordinary vessels and one of the most important in the whole body, sometimes called the Sea of Blood and the Sea of the twelve meridians. This dual membership gives the point a reach that goes beyond simple local action.
Five-element dynamics
The Kidney channel is the Water channel, the deepest and most fundamental of the Yin channels. And the Penetrating vessel, which the Kidney channel shares at this point, runs right through the core of the body, connecting the lower, middle and upper regions. When the two meet at Shangqu (KI-17), the point sits at a kind of internal crossroads — capable of influencing the deep layers of the abdomen where accumulations and blockages take root. Water, when it stagnates, creates accumulation; when it moves again, it flushes what was stuck. That is the logic of this point.
Location
Find the navel, then measure 2 Cun straight upward. From there, move just 0.5 Cun to the side of the midline — that is where Shangqu (KI-17) sits, level with Xiawan Ren-10.
Anatomy & fascia
The point lies on the upper abdomen, in the region of the rectus abdominis muscle.
Needling
The needle is inserted perpendicularly (straight in).
Safe depth
1 to 1.5 Cun. ⚠️ Caution: deep needling at this abdominal location may penetrate the peritoneal cavity — stay within the safe depth.
Moxa, cupping & Tui Na
Moxibustion can be applied here, especially when Cold is involved in the accumulation or when there is intestinal cold with cutting pain. Gentle abdominal massage along the Kidney channel line on the abdomen may complement treatment.
Functions
Dispels accumulation and alleviates pain. Regulates the intestines and restores smooth bowel movement.
Indications
Abdominal masses (ji ju type — masses that come and go or shift) with periodic cutting pain. Intestinal pain accompanied by lack of appetite. Vomiting, diarrhoea, constipation. Redness and pain of the eye originating at the inner canthus.
Point combinations
With nearby Kidney channel abdominal points such as Huangshu KI-16 for chronic accumulation disorders in the abdomen. The point can be combined with local points along the Ren channel when treating digestive blockage and intestinal pain.
Clinical spotlight
What makes Shangqu (KI-17) stand out among the abdominal Kidney channel points is its specific action on accumulation — the Chinese term ji ju refers to masses in the abdomen, particularly those that are not fixed, that come and go or are felt periodically with cutting, cramping pain. This is a deeper, more stubborn kind of stagnation than ordinary Qi Stagnation, and Shangqu (KI-17), through its connection with the Penetrating vessel deep in the body's core, is positioned to address it. The additional indication of eye redness at the inner canthus is a reminder that the Kidney channel, running upward through the body, can influence distant areas far from the point's location.
The golden tip
If you are dealing with cramping abdominal discomfort or sluggish digestion, you can gently press or massage the area 2 Cun above the navel and just beside the midline. Use slow, firm circular pressure for a minute or two. Warmth — a warm pack held over the area — can also help ease intestinal cold and tightness. As always with the abdomen, keep pressure gentle and comfortable.
