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.

These uses document historical traditions and do not imply proven effectiveness.

Research Summary

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.

Evidence levels reflect the currently available scientific literature and may change as new research emerges. Where evidence is limited or conflicting, this is stated plainly.
