Xi-Cleft point

Traditionally used for

  • Digestion
  • Bowel health
  • Menstrual & women's health
  • Nerves & recovery

Location

On the anteromedial aspect of the lower leg, at the centre of the medial surface of the tibia, 7 cun above the prominence of the medial malleolus — 0.5 cun below the midpoint of the line from the apex of the patella to the medial malleolus.

Focks' Atlas of Acupuncture places it just posterior to the medial crest of the tibia rather than on the centre of the medial surface.

How to locate: Measure 7 cun up from the prominence of the medial malleolus; to check, find the midpoint of the line from the malleolus to the apex of the patella (the spreading-hands method helps) and go 0.5 cun below it. The point is on the centre of the medial surface of the tibia.

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