P-6 is located how many cun proximal to P-7?

P-6, also known as Neiguan, is located on the inner forearm, specifically in the space between the tendons of the palmaris longus and flexor carpi radialis muscles. P-7, or Daling, is situated on the same line but is more distal, at the wrist crease.

The standard measurement of distance in traditional Chinese medicine for acupuncture points is using "cun" as a unit based on the patient's own anatomy. In the case of P-6 and P-7, P-7 is considered to be approximately 1 cun proximal to the wrist crease, and since P-6 is located 2 cun proximal to P-7, it's indicated that P-6 is indeed 2 cun above P-7 on the forearm.

Recognizing these specific anatomical relationships and the proper use of "cun" measurement is essential for accurately locating acupuncture points and providing effective treatment. This knowledge underlines the importance of understanding point locations in relation to each other when learning acupuncture.
