Overview

Kudzu root is the source of the familiar hangover tea (galgeun-cha) still sold across Korea today. The Donguibogam records it as releasing the exterior, promoting sweating, resolving alcohol toxicity, and relieving thirst — the very same properties behind its modern reputation as a hangover remedy.

TranslationIts nature is neutral (some say cold), its taste sweet, and it is non-toxic. It mainly treats wind-cold headache. It releases the muscle layer and exterior, induces sweating and opens the pores, resolves alcohol toxicity, relieves vexing thirst, and opens the appetite to aid eating. It treats chest-diaphragm heat, unblocks the small intestine, and heals wounds from metal.
