SP2 · 足太阴脾经

Dadu dà dū · 大都

Location. On the medial side of the great toe, in the depression distal and inferior to the first metatarsophalangeal joint, at the border of the red and white skin.

Category. Ying-spring 荥穴

The name means "great capital" — classical naming uses city imagery for the broad, fleshy part at the base of the great toe. This is a naming convention, not a claim about effect.

定位。在足大趾内侧,第 1 跖趾关节远端前下方赤白肉际凹陷处。

特定穴。Ying-spring 荥穴

穴名意为「大都邑」,古典以都邑之象命名足大趾本节丰厚之处。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.
Low risk in routine practice. The skin is thin over the joint and the joint capsule lies directly beneath, so the point should not be needled into the joint itself.
