Rugen rǔ gēn · 乳根

Location. On the chest, in the 5th intercostal space, 4 cun lateral to the midline, directly below the nipple.

The name means "breast root" — the point sits at the base of the breast, below the nipple. Classical naming here describes the place rather than any use. This is a naming convention, not a claim about effect.

定位。在胸部,乳头直下,第 5 肋间隙,距前正中线 4 寸。

穴名意为「乳之根」,位于乳房下缘、乳头直下。穴名记部位,不含用途表述。此处为命名描述,不涉及疗效主张。

Classical record · not a treatment recommendation. Needling technique is a licensed practitioner's skill and is out of scope here.
Over the lower chest with the lung and heart border beneath; pneumothorax is the recognised risk of needling too deeply here, so depth and angle are a practitioner judgement. Not suitable for self-treatment.
