Facial paralysis
When the mouth and eyes are crooked, apply 3 x 7 moxa cones at acupuncture points LI4 (??), ST4 (??), RN24 (??), ST5 (??), ST36 (???) and PC5 (??).
The other way is to put a reed 5 cun long inside the ear, clog the space around the reed with some dough to prevent any leakage. And then, apply 7 to 2 x 7 moxa cones at the reed tube. Change the reed and repeat it.
