Yaoyan yāo yǎn · 腰眼

Location. On the low back, in the depression about 3.5 cun lateral to the lower border of the spinous process of the fourth lumbar vertebra.

The name means the eye of the low back, referring to a natural hollow rather than to the eye itself. It is a point outside the fourteen channels. Classical texts associate the point with the low back and the kidney region; the reported effects are not established by modern research, and this entry makes no claim of benefit.
