The Food Cavity of the Spleen channel — a specialised point on the chest wall that moves stuck food and rebellious Qi in the lateral ribs, diaphragm and abdomen. Not a famous daily-use point, but one the old texts held in extraordinary regard for severe Spleen disease.
Name & story
The name 食窦 Shidou means "Food Cavity" or "Food Hollow". It paints a vivid picture: a cavern or hollow where food gathers and can become stuck. The Spleen's job is to transform what we eat and send nourishment upward; when that process fails, food stagnates and settles into the body like something lodged in a cave. This point, sitting on the lateral chest near where the Spleen channel travels, was understood as the place to open that cave — to let the stuck food and Qi move again.
Point family & character
Shidou SP-17 belongs to the Spleen Meridian (SP). It sits on the lateral chest and is not classified among the commonly cited special point categories, but it holds a notable place in classical literature as a powerful point for major Spleen disease.
Five-element dynamics
The Spleen belongs to the Earth element and is the great organ of transformation — it turns food and drink into Qi and Blood (Xue) for the whole body. When the Spleen falters, food does not transform properly; it stagnates, producing distension, belching, nausea and undigested matter in the stool. Shidou SP-17 addresses exactly this failure: it moves the stuck food and rebellious Qi that arise when the Earth element loses its ability to process and distribute nourishment.
Location
On the lateral chest, in the fifth intercostal space, 6 Cun lateral to the midline. The intercostal spaces are most reliably counted downwards from the second intercostal space, which lies just below the sternal angle.
Anatomy & fascia
The point lies on the lateral side of the chest, in the fifth intercostal space, over the intercostal muscles.
Needling
Transverse-oblique insertion along the intercostal space. Always needle carefully along the rib space and never drive the needle perpendicularly into the chest wall.
Moxa, cupping & Tui Na
Moxibustion holds a special place at this point. The Book of Bian Que's Secrets states that in severe Spleen disease, when life is hanging by a thread, applying 200–300 moxa cones here can assure the patient's survival. While this kind of extreme application belongs to classical emergency medicine, the passage speaks to how deeply the tradition trusted warming this point in serious Spleen conditions.
The golden tip
Because of its location on the chest wall and the need for careful needling technique, this point is not suitable for self-needling at home. If the area feels tight or painful, gentle fingertip pressure along the fifth intercostal space on the side of the chest may offer some comfort. Warmth applied over the lateral ribcage — a warm compress or gentle heat — can help ease diaphragmatic tension and a sense of food sitting heavily.
