A quiet but capable point on the upper chest, Yuzhong (KI-26) is where the Kidney channel reaches toward the lungs — calming the breath, clearing congestion in the chest and helping Qi descend when it rebels upward.
Name & story
The name 彧中 Yuzhong is sometimes rendered as "Comfortable Center" or "Elegant Middle" — 彧 (yu) carries a sense of refinement, culture and ease, while 中 (zhong) means center or middle. The image is of the chest finding its ease again: breathing that has been tight, congested or restless becomes settled and spacious. There is something gentle in that name — not a point that forces or drives, but one that restores a kind of cultivated calm to the center of the chest.
Point family & character
KI-26 belongs to the Kidney Meridian (KI). It is part of the upper thoracic section of the channel, where the Kidney channel ascends through the chest toward the clavicle. At this level the channel runs close to the Lung, and the point is well placed to regulate the relationship between Kidney and Lung — the two organs that together govern the breath.
Five-element dynamics
The Kidney belongs to Water, and the Lung to Metal — and in the Five Element cycle, Metal is the mother of Water. KI-26 sits right at the border where these two organs meet in the chest. When Kidney Qi is too weak to anchor the Lung's descending Qi, the breath rebels upward: coughing, wheezing, tightness. This point helps restore that downward flow — drawing the Qi back to its root, calming the chest and allowing the breath to settle.
Location
KI-26 is found on the chest, in the first intercostal space (between the first and second ribs), 2 Cun lateral to the midline — that is, 2 Cun to the side of Ren-20 (Huagai).
Anatomy & fascia
The point lies on the chest wall, over the costal cartilage, in the region of the pectoralis major muscle.
Needling
The needle is inserted obliquely or transversely along the intercostal space. Care is taken not to needle too deeply because of the underlying lung tissue.
Moxa, cupping & Tui Na
Gentle massage or acupressure over the point can help ease chest tightness and encourage the breath to deepen and slow. Moxa is applicable where there is Cold or Qi Deficiency affecting the chest.
Functions
Descends rebellious Qi and calms the breath; Opens and relaxes the chest; Resolves Phlegm; Clears Heat from the chest; Suppresses cough and relieves wheezing.
Indications
Cough, wheezing and breathlessness — particularly when Qi rebels upward and does not descend. Fullness, stuffiness and pain in the chest. Accumulation of Phlegm in the chest. Difficulty swallowing, sensation of obstruction in the throat or chest. Vomiting and nausea where rebellious Qi is involved.
Mind & spirit (Shen)
The chest is where the Shen — the Heart's spirit — resides, and when the chest is congested and tight, the mind feels the same way: anxious, oppressed, unable to breathe freely or think clearly. By opening the chest and bringing Qi back down, Yuzhong creates room — a literal and figurative space in which the Shen can settle. That quiet sense of refinement suggested by the name is not only physical: when the breath finds ease, so does the mind.
Point combinations
Paired with Lung channel points such as LU-7 (Lieque) to descend Lung Qi and calm cough and wheezing. Combined with Ren-17 (Danzhong) — the influential point of the chest — to open fullness and tightness in the chest. With KI-27 (Shufu), its neighbor on the Kidney channel, to reinforce the descending of rebellious Qi from the chest.
Clinical spotlight
KI-26 occupies a meaningful position in the Kidney channel's thoracic pathway — the stretch where the deepest Yin organ of the body reaches up toward the Lung. Its strongest suit is rebellious Qi in the chest: coughing that will not stop, wheezing, a feeling of fullness pressing upward. Because it acts both on the Kidney (the root of the breath) and the Lung (its expression), it addresses the breath from both ends — anchoring it below and opening it above.
The golden tip
If the chest feels tight or the breath seems stuck, you can find Yuzhong by placing two fingers to the side of the breastbone, just below the collarbone, at the level of the first intercostal space. Gentle circular massage here for a minute or two — breathing slowly and deeply as you do — can help the chest open and the breath settle.
