  • Nose & throat

Location

On the lateral side of the second toe, 0.1 finger-cun proximal and lateral to the lateral corner of the nail — where lines along the lateral border and the base of the nail intersect.

How to locate: Draw one line along the lateral border of the second toenail and another across its base; the point is where they cross, about 0.1 cun from the nail corner.

Distances are in cun, a proportional unit — how to measure.

Clinical Notes

The classical point for disturbed dreaming and restless sleep attributed to Stomach heat — 'when the Stomach is disharmonious, lying down is not peaceful.'
