What Touwei does
Touwei is treated here as a practical point rather than a curiosity: where it sits, how it is needled, what the tradition says it does, and the skin conditions in this database that name it.
Actions
- Expels Wind
- Relieves pain
- Benefits eyes
Location
Half a cun measured from the landmark shown in the diagram and the location text, at the temporal corner of the forehead, on the border of the temporalis muscle.
How to find it
Find the bony strongest first, then feel for the hollow or tender spot the location describes. The point is usually sensitive when pressed.
Deqi
De qi at this point is felt as local distension, heaviness or aching, and may travel a short way along the channel.
A cun is a proportional body measurement, not a fixed length: one cun is about the width of the thumb at the knuckle, 1.5 cun about two finger widths, and 3 cun about the width of four fingers. On an average adult one cun is roughly one inch, but it scales with the person, which is why the texts measure in cun rather than centimetres.
Technique
Needling
Angle: 15 degrees, transverse Depth: Standard depth half a to one cun. Direction: Needle in the direction the location describes.
Moxibustion
Moxibustion is used where the pattern is cold or deficient, in short sessions.
Skin uses
Touwei is a Stomach channel point at the temporal corner of the forehead, recorded to expel Wind, relieve pain and benefit the eyes. The location is the basis for a local, cautious skin reading: lesions on the temple and forehead are sometimes considered through it, and the Wind action is traditionally linked with symptoms that come and go. Its classical record describes head wind and eye pain rather than the skin. No skin-specific classical indication is recorded for the point, and the reasoning above is an indirect rationale, not trial evidence.
No skin-specific classical indication is recorded for this point. The rationale above is an indirect, traditional reading of the point, not a promise of benefit.
