GB-20 Fengchi
GB-20 Fengchi (風池) is a point on the Gallbladder 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
In the depression below the occiput, between the upper attachments of the sternocleidomastoid and trapezius muscles.
How to find it
Follow the neck muscles up to the base of the skull. The points are in the two hollows between the muscles, just below the ridge of the skull.
Traditional functions
- Clears wind and benefits the head and eyes
- Relaxes the neck
- Benefits the sensory organs
Traditional uses
- Headache and neck tension
- Eye strain
- Dizziness
- Nasal congestion and ear stuffiness in traditional practice
How to press it
Press upward toward the skull with the thumbs for 1–2 minutes, breathing slowly. Let the head relax forward slightly.
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 with a neck injury or after recent surgery. Sudden severe headache, weakness, or vision loss requires emergency care.
How this is viewed today
GB-20 is widely used in trials for tension-type headache and neck pain. Reviews report modest short-term effects.
