A true classic candy everyone should try!. It's the flavor of the pioneers, of settlers and the British who originally brought horehound to North America in the 1600s. While the plant is of the mint family, its flavor is hard to explain. Some say it's a mix of licorice and root beer.Other say it tastes like bitter herbs. IN FACT, many believe horehound is the Biblical bitter herb.In addition, horehound has long been considered a medicine, good for stomach upset, sore throats and more. Those are but a few reasons to try it. Oh - about the name. The leaves are "hoary," meaning they have down, much lie little hairs, on them.
