Where is the K-8 point located?

The K-8 point, also known as "Jiao Xin," is located 2 cun above the K-3 point, which is situated on the medial side of the ankle. This specific distance of 2 cun above K-3 is significant for acupuncture and herbal practitioners, as K-8 is traditionally used in treatments related to kidney and urinary issues, as well as gynecological conditions. Its location makes it accessible and practical for practitioners to target the areas associated with its therapeutic effects.

Understanding the anatomy and terminology of acupuncture points is essential since practitioners often utilize these points for specific conditions based on their relative locations. In this context, knowing that K-8 is indeed positioned above K-3 helps to emphasize the importance of precise anatomical references in acupuncture practice.

The other options suggest incorrect distances or placements that do not align with established acupuncture point locations. Therefore, B is the correct answer as it accurately describes the position of the K-8 point in relation to K-3.
