This point is located on the inner aspect of the knee, in the depression at the medial end of the popliteal crease, just posterior to the medial epicondyle of the tibia. It lies between the tendons of the semitendinosus and semimembranosus muscles and is most easily found when the knee is slightly flexed.
From a Traditional Chinese Medicine (TCM) perspective, LV8 is the He-Sea and Water point of the Liver channel. Its primary functions are to nourish Liver Blood and Liver Yin, making it especially useful in conditions of deficiency such as dizziness, dry eyes, or irritability. It also benefits the uterus and helps regulate menstruation, so it is commonly used for issues like irregular cycles, amenorrhea, infertility, or abnormal uterine bleeding. In addition, LV8 clears damp-heat from the lower jiao, addressing symptoms such as genital itching, swelling, or painful urination. Because the Liver governs the sinews, this point also helps lubricate and strengthen tendons, making it relevant for knee pain or weakness in the legs.
From a Western medical perspective, LV8 has a strong local effect on the medial knee. It influences structures such as the medial collateral ligament, the pes anserinus tendons, and the surrounding joint capsule, helping to improve circulation and reduce inflammation. Needling this point may also relax the nearby hamstring tendons and modulate pain through stimulation of branches of the tibial nerve. Clinically, it is often used for medial knee pain, arthritis, hamstring tightness, and restricted range of motion.
Overall, Liver 8 is particularly valuable in presentations that involve both deficiency and stagnation, such as when Liver Blood or Yin deficiency coexists with dampness or localized obstruction. This dual action makes it a versatile point in clinical practice, addressing both systemic imbalances and local musculoskeletal issues.
