Clinical notes

As the Yuan-Source point of the Bladder channel, Jinggu is a key point for treating disorders along the entire channel, from headache and neck stiffness to lumbar and leg pain. Its classical indications for mania, epilepsy, and fright highlight its function in calming the spirit, particularly when Bladder channel pathology affects the head and mind. It is also an important distal point for eye disorders like redness and pain, especially at the inner canthus, reflecting the channel's origin at Jingming (BL1).
