KI-6 Zhaohai
KI-6 Zhaohai (照海) is a point on the Kidney meridian. In TCM theory it is described as influencing the channel's qi, and it is traditionally used in the context of the whole pattern rather than as a stand-alone remedy. This page explains how to locate it, what the tradition says about it, and how to press it safely.
Location
One cun below the medial malleolus, in the depression at the lower border of the bone.
How to find it
Find the inner ankle bone, then slide one finger-width straight down into the hollow below it.
Traditional functions
- Confluent point of the Yin Heel Vessel
- Nourishes yin and moistens the throat
- Regulates sleep
Traditional uses
- Insomnia and restless sleep
- Dry throat and mouth at night
- Anxiety in traditional practice
- Medial ankle discomfort
How to press it
Press gently for 1 minute on each ankle in the evening, paired with slow breathing.
Acupressure is generally a gentle practice. Use the pad of the thumb or finger, start with light pressure, and increase only to a comfortable level. A mild ache or warmth is common; sharp pain is a signal to ease off.
Safety
Avoid strong pressure during pregnancy. Do not press over an injured or swollen ankle.
How this is viewed today
KI-6 is used in trials for insomnia and dry mouth, often with LU-7. Evidence remains preliminary.
