CLEARS LIVER FIRE & BRIGHTENS THE EYES: Qin Pi also goes to the liver and GB channels, where it helps to remove heat causing redness, swelling, pain, visual obstruction.
"You're the Qin Pi of my eye!"

DISPERSES WIND DAMP for painful obstruction

CALMS WHEEZING / STOPS COUGHS due to lung heat (huh? It doesn't go the lung, but I guess it has a general heat clearing function...)

Qin Pi, according to Bensky, enters the qi level (one way to remember Qin goes in the Qi level). It is good with Bai Tou Weng for treating dysentery. Bai Tou Weng enters the blood level, eliminating the heat toxin, and Qin Pi "cools the large intestine, dries damp, and stops dysenteric disorder.
