The exact location of the bile meridian in the thigh is located on the medial axis of the lateral thigh. The patient can determine the route of the bile meridian by connecting two acupuncture points. The two acupoints are the Huanjiao point and the Knee Yangguan point. The ring jump point is located at the junction of the outer and outer 1/3 of the line connecting the greater trochanter of the femur and the sacral fissure, which is also located on the outer lower side of the hip. The knee Yangguan point is located three inches above the Yangling Spring, in the depression above the lateral epicondyle of the femur. The patient can first feel upward at the outermost, lowermost part of the femur, which is the outermost part of the knee joint, and gradually feel upward to a depression above the femur, which is the Knee Yangguan point. The bile meridian follows the route of the two points and can treat diseases such as impotence of the lower extremities, hemiplegia, numbness of the lower legs and other lower extremity knee related diseases.
