Small Intestine channel · point 1
Traditionally used for
- Headaches
- Eye health
- Nose & throat

- Menstrual & women's health
Location
On the ulnar side of the distal phalanx of the little finger, 0.1 finger-cun proximal-medial to the ulnar corner of the nail, where the line of the ulnar border of the nail meets the line of the nail base.
How to locate: At the ulnar corner of the little fingernail, find where lines along the ulnar border and the base of the nail cross, about 0.1 cun from the corner; HT9 is at the radial corner.
Distances are in cun, a proportional unit — how to measure.
