The needling technique and clinical application of point Zhibian.

Point Zhibian (BL 54) is often used for treatment of lumbago and scelalgia, flaccidity and arthralgia of the lower limb, constipation and dysuria, and hemorrhoid. As for the needling, the direction of the needle tip may vary, generally in three directions: 1) along the channel itself, 2) pointing to the genitals, and 3) pointing to the anus, the purpose of which is "leading qi to the diseased area" so as to obtain "effectiveness upon the arrival of qi". This point can also be used in combination with moxa stick, cupping, and point injection according to the individual conditions. However, only by differential application, can this point produce better therapeutic effects.
