Best Clinical Use

  • Neck pain along the Gallbladder channel.


Needle it perpendicularly 1/2 to 1 cun in depth.
Dr. Robert Chu recommends 1/2 cun and says you don’t need to force the Qi to come with manipulation. In my experience I’ve found he’s right. I sometimes needle Ling Gu and Da Bai on the unaffected side and then these points on the affected side.
