Fennel is a tall herb with hollow stems and yellow flowers. Originally native to the Mediterranean, it grows all over the world and has been used for centuries as a medicinal plant. Fennel seeds can be dried and used to make a potent and strong-smelling tea. The tea tastes a little like licorice, with a relaxing scent and slightly bitter aftertaste. Fennel tea can be purchased in almost any supermarket or health food store. Fennel has long been thought to strengthen your eyesight, regulate hormones, improve your digestion, and help memory.
