Classifications:

Xi-Cleft point
Binding point of the hand Taiyang Sinews


Location:

When the palm of the hand is placed on the chest, this point is located on the dorsal aspect of the head of the ulna, in a cleft level with and to the radial side of the high point of the styloid process of the ulna. It is most easily located by asking the patient to place their arm by their side and their hand prone, and the practitioner placing a finger on the high point of the ulna styloid process. Ask the patient to place their palm on their chest and the point is found in the cleft where the practitioner's finger will rest.

Oblique of transverse-oblique insertion distally or proximally 0.5 - 1 cun


Classical Needling:

"The Taiyang usually has much Blood and little Qi" (Su Wen 素問 ch. 24) implying this channel should normally be bled.
"The hand Yin and Yang receive their Qi via nearby paths so their Qi arrive swiftly. The depth of piercing must not exceed 2 fen and must not remain inserted for longer than one exhalation" (Ling Shu 靈樞 ch. 12).
"It is needled to a depth of three fen, and it is moxaed with three cones" (Huangfu Mi 皇甫謐, 3rd Century, Zhenjiu Jiayi Jing 針灸甲乙經).
