“Anise-flavored” is the term used most often to describe fennel's flavor—but that doesn't mean it tastes like a licorice stick! In fact, fresh fennel's anise factor is delicate and mild; many self-proclaimed licorice-haters find that they actually like it. Fennel is used for various digestive problems including heartburn, intestinal gas, bloating, loss of appetite, and colic in infants. It is also used for upper respiratory tract infections, coughs, bronchitis, cholera, backache, bedwetting, and visual problems.
