Discussion: Kou Pi (Facial Paralysis/Deviation of Mouth and Eye) occurs due to body deficiency allowing wind pathogen invasion; the wind enters the tendons flanking the mouth. The tendons of the Foot-Yangming Meridian ascend and flank the mouth. When these tendons are deficient on one side, wind exploits the deficiency, causing unilateral tendon spasm and dysfunction, resulting in deviation of the mouth and eye.
Treats sudden onset of facial paralysis, stiff and urgent speech, while limbs remain normal with no other discomfort.

Treats facial paralysis: Use 7 seeds of Bimazi (Semen Ricini), remove shells, grind finely into a paste, apply to the palm (apply to left palm for right-sided deviation, to right palm for left-sided deviation). Then place a copper bowl filled with hot water over the medicine to steam it. Wash off immediately once correction is achieved. (Another formula uses Badou (Semen Crotonis) instead of Bimazi. From *Ben Cao*)
