Zhibian BL-54 is not used for its energetic function, but it is a very important local point to remove obstructions from the Channel, so that it treats lower back pain, especially if it spreads to the legs and buttocks as well. In this case, it should always be checked for tenderness. A long needle (at least 5 cm) should be used if it is tender.
Ideally, the needling sensation should reradiate all the way down to the foot, then the single use of BL-54 is enough. Otherwise, other points can be needled to strengthen the effect. Furthermore, if the pain is caused by Cold or Dampness invading the Channel, moxibustion can be used together with needling.
BL-54 also treats urinations issues and haemorrhoids.
