Deglycyrrhizinated licorice (DGL) is most commonly used to alleviate symptoms of chronic indigestion, heartburn, stomach ulcers, and canker sores. Whole licorice extract is used for menstrual and menopausal disorders and inflammatory disorders. Topical whole licorice is sometimes used for herpes, eczema and psoriasis.
While licorice is sometimes used as a flavoring in food, particularly in candy, most "licorice" or "licorice flavored" products available in the U.S. do not actually contain licorice. Instead, food makers use anise oil, which smells and tases very similar to licorice (though is not).
