Commentary:

Weizhong is the He-Sea point of the Urinary Bladder channel. A He-Sea point, according to 5 Elements theory, is where the Qi of the channel plunges deeply within.

Weizhong appears on the list of 'Twelve Heavenly Star Points', long considered the pre-eminant list of the most important acupuncture points.

Weizhong is the point of choice for Lumbar pain regardless of the cause, whether acute, or chronic. It is also important for knee pain, and pain of the lower leg.

Weizhong is one of the few points that is routinely 'bled'. This is still an important treatment method in TCM, despite western views that it is an archaic and obsolete practice.

'Pricking to bleed' this point is an effective treatment not only for back pain due to stasis, but for nosebleed, and because of its action of cooling the blood for a variety of skin disorders.

Finally, Weizhong is indicated for a disorders of the Bladder, including various urinary problems.
