Fennel has long been considered good for digestion, and fennel tea is a popular after-dinner drink in some parts of the world. Proper Italian sausage demands whole fennel seeds, which are also commonly found in fish dishes. It’s used in curing mix for salmon or bluefish and it is also sometimes added to cheese.
The use of fennel dates back to thousands of years ago when Hindu and Chinese people used it as a cure for snake bites. During the Middle Ages, Fennel was hung above doorways to ward off evil spirits.
