Clinical notes

As the Jing-River and Fire point of the Gallbladder channel, Yangfu is excellent for clearing heat and resolving stagnation along the entire channel pathway. It is a key distal point for pain in the hips, lateral leg, and ankle, especially for conditions involving wind-damp, such as migratory joint pain (bi syndrome). Its ability to treat axillary and neck swelling (scrofula) demonstrates its action on clearing phlegm-heat from the channel. Clinically, it is frequently combined with GB34 (Yanglingquan) for sinew and joint problems of the lower limb and with points like GB41 (Zulinqi) for pain along the side of the body.
