small intestine: needles

si1

Perpendicular or oblique insertion directed proximally 0.1 to 0.2 cun, or prick to bleed

si2

Oblique distal insertion 0.2 to 0.3 cun; ii. Perpendicular oblique insertion towards the palm, 0.5 cun.

si3 (confluent point of the governing vessel)

Perpendicular insertion 0.5 to 2 cun, directed towards Sanjian L.I.-3.

caution- needle with the hand in a loose fist position, i.e. with the metacarpal bones lying in the same plane; this is especially important when needling deeply towards the opposite side of the hand

si4 (yuan source)

Perpendicular insertion 0.3 to 0.5 cun

si5

perpendicular insertion .3-.5 cun

si6 (xi cleft)

Oblique or transverse-oblique insertion distally or proximally, 0.5 to 1 cun

si7 (luo connecting)

perpendicular insertion .5-1 cun

si8

Oblique distal or proximal insertion 0.5 to 1 cun; ii. Perpendicular insertion 0.3 to 0.5 cun.

Caution: the ulnar nerve lies deep to this point.

si9

perpendicular insertion 1-1.5 cun

si10

perpendicular insertion 1-1.5 cun

si11

perpendicular or oblique insertion .5-1.5 cun

si12

Oblique medial insertion towards the spine 0.5 to 1 cun.

Caution: deep perpendicular insertion, especially in thin patients, carries a substantial risk of inducing a pneumothorax.

si13

Perpendicular insertion 0.3 to 0.5 cun; ii. Oblique lateral insertion 0.5 to 1 cun.

Caution: this point is located close to the medial border of the scapula. Too medial an insertion or deep medial-oblique needling may puncture the lungs.

si14

Oblique medial insertion 0.5 to 1 cun.

Caution: perpendicular insertion, especially in thin patients, carries a substantial risk of inducing a pneumothorax.

si15

Oblique medial insertion towards the spine 0.5 to 1 cun.

Caution: deep insertion inferiorly, especially in thin patients, carries a substantial risk of inducing a pneumothorax.

si16 (window of heaven)

perpendicular insertion .5-.8 cun

si17 (window of heaven)

Directed towards the root of the tongue, anterior to the

carotid vessels, 0.5 to 1 cun

si18

Transverse insertion joined to points such as ST-4, ST-7, L.I.-20, ST-6 etc.; ii.

Perpendicular insertion 0.5 to 0.7 cun.
caution: contraindicated moxibustion.

si19

perpendicular insertion 0.5 to 1 cun; ii. Needle with the mouth open; following insertion of the needle the patient may close their mouth.
