Taiyuan tài yuān · 太渊

Location. At the wrist crease on the radial side, where the radial artery is felt.

Category. Shu-stream + Yuan-source + hui of vessels 输穴·原穴·脉会

Both the stream and source point of its meridian, and the meeting point of vessels — unusual to hold three roles.

特定穴。Shu-stream + Yuan-source + hui of vessels 输穴·原穴·脉会

同时为本经输穴、原穴,并为八会穴之"脉会"——一身兼三职,较为特殊。

Classical record · not a treatment recommendation. Needling technique is a licensed practitioner's skill and is out of scope here.
The radial artery runs here; classical texts advise avoiding the vessel.
