Extraordinary vessel
Yang Qiao
The yang heel vessel. BL62 opens it.
Yang Qiao runs the outer body. BL62 opens it, with SI3 as the coupled point — the same pair, reversed, that opens the Du vessel. The shared points are a memory hook, not two names for one channel.
Classical indications include a tight outer leg and certain eye and sleep pictures, including historical notes on seizures. Seizure care is emergency medicine. The vessel page is for orientation only.
