Botanical Description

A tall aromatic perennial 1.5–2.5 m with feathery, thread-like bluish-green leaves, umbels of tiny yellow flowers, and ribbed green-brown seeds. The seeds are the primary medicinal part; the bulb is culinary.

Also known as: Sweet Fennel, Finocchio

Historical Background

Fennel seed has soothed digestion in Mediterranean, Indian, and Chinese households for millennia — chewed after meals, brewed as tea, and used in Ayurvedic and Unani digestive formulas. The Greeks named it 'marathon' (marathron), giving Marathon its name.

Earliest recorded uses: Egyptian, Greek, and Ayurvedic texts; Dioscorides describes fennel.

Cultural significance: Fennel gave the Greek plain of Marathon its name (from marathron, fennel) and is chewed after meals across India and the Mediterranean — a universal after-dinner digestive.

Modern Evidence

Fennel is widely used for digestive comfort and as a galactagogue, with limited clinical evidence; a few small trials suggest benefit for infantile colic and menstrual pain, but quality is low. Estrogenic compounds warrant caution in pregnancy and hormone-sensitive conditions.
