    Horehound is of the mint family and though introduced from Europe, it now grows wild in North America.

    The plant is a source of flavoring for candies, teas, and syrups used in folk medicine as cough and cold remedies. Pharmacologists agree that it is likely an expectorant. It is also sometimes used by herbalists as an appetite stimulant.

    A decoction of horehound mixed with honey produces a syrup used to inhibit coughing, but my personal favorite is the candy that is made from it in much the same way and is used as a cough drop.
