Overview
Yuja is the citrus behind yuja-cha (citron tea), a Korean winter staple, and the Donguibogam already records its two signature uses: clearing foul qi from the stomach and resolving the toxic aftereffects of alcohol — the very same reputation yuja tea holds today as a hangover and cold remedy.
