6. Clinical notes
LV 4 is the Jing-River and Metal point of the Liver meridian. It is primarily used for disorders of the Liver channel in the genital region — orchitis, epididymitis, hernia and genital pain — where it is combined with LV 5 and LV 1. Its location at the medial ankle also makes it useful for medial ankle conditions.
