유자쌍화 (Yuja Ssanghwa) is a Korean herbal tea that blends yuja (yuzu citrus) with ssanghwa, a traditional tonic made from multiple medicinal herbs.

The drink is known for its immune-boosting, energizing, and warming properties—excellent for fatigue or on cold days. 쌍화 provides a gentler long-term energy boost, a bit different than a caffeinated energy drink.
