Overview
Licorice root appears in more traditional Korean formulas than almost any other herb. Known as the harmonizer, it is used to moderate and unify the actions of other ingredients, ease the digestive system, and soothe coughs. The Korean saying 'like licorice in the medicine cabinet' describes something present everywhere.

Frequently asked questions
Why is licorice in so many formulas?
Traditional sources describe licorice as harmonizing the hundred medicines: it moderates harsh ingredients, unifies a formula's action, and improves taste.
Is licorice root the same as licorice candy?
Not exactly. The herb is the dried root; much modern candy is flavored with anise instead of real licorice.
