GB-38 is located how many cun superior to the lateral malleolus?

GB-38, known as Yangfu, is located on the lateral side of the lower leg, and is specifically found 4 cun superior to the lateral malleolus. The understanding of cun measurement, which is based on the patient's own anatomical proportions (with one cun generally being the width of the patient's thumb at the level of the knuckle), is essential in acupuncture practice for precise point localization.

This point is clinically significant as it is located on the Gallbladder meridian and is often used in treatment for various health conditions, particularly those involving the gallbladder and liver. Additionally, it can influence the sinews and alleviate pain or discomfort in the lower limb region.

Being aware of the exact distance from anatomical landmarks like the lateral malleolus is crucial not only for effective treatment but also for ensuring patient safety during acupuncture. In this case, recognizing that GB-38 is 4 cun superior adds to a clearer understanding of point location relative to other structures in the body.
