Traditional uses

Fennel has been chewed after meals from ancient Rome to modern India, a habit that grew out of centuries of trust in its ability to settle an uneasy stomach. Greek and Roman physicians recommended it for digestion and eyesight, and medieval herbalists hung it over doorways believing it warded off illness and evil spirits alike. Across cultures, nursing mothers turned to fennel seed tea in hopes of supporting a healthy milk supply, a use that carried it into kitchens and apothecaries side by side. It has long been considered one of the gentlest, most companionable herbs in the traditional digestive repertoire.

Did you know?

The ancient Greek word for fennel, marathon, gave its name to the town of Marathon and, eventually, to the 26.2 mile race, since the battlefield where the famous run began was once a field of wild fennel.

Safety

Fennel is safe in ordinary culinary amounts, though those allergic to carrot, celery, or parsley should watch for cross-reactivity. Its estrogen-like compounds mean concentrated or medicinal amounts are best avoided during pregnancy, and the essential oil should not be taken internally.
