How many cun are there in the measurement of the medial leg?

The measurement of the medial leg is standardized in acupuncture, and it is typically measured from the tip of the medial malleolus (the bony prominence on the inner side of the ankle) to the popliteal crease (the back of the knee). This distance is generally accepted to be 15 cun in adults. The cun measurement is a traditional Chinese medical unit based on the width of the patient's own thumb, providing a customizable and relative measurement method.

This standardized length is important for accurately locating acupuncture points along the medial side of the leg, as well as ensuring consistency in treatment regardless of the physical attributes of different patients. Understanding this measurement is crucial for practitioners to effectively administer acupuncture and achieve therapeutic outcomes.
