Feiyang BL-58 is the Connecting-Luo point of the Bladder Channel and it communicates to the Kidneys. When combined with Taixi KI-3, it strongly strengthens the Kidneys. Thus it treats symptoms such as lower back pain, tinnitus and dizziness.
Furthermore, it removes obstructions from the Channel, thus it treats lower back pain, sciatica, leg atrophy as well as the difficulties to stand.
Finally, the Bladder Channel passes the anus, so BL-58 is often used as a distal point to treat haemorrhoids.
