Origin
France
Fennel has accompanied human civilization since antiquity. The ancient Egyptians used it in cooking and medicine, and the Greeks associated it with strength and rejuvenation, believing it could restore vigor. The Romans, never one to miss a culinary opportunity, used fennel extensively in both food preservation and festival dishes.
The botanical name Foeniculum vulgare reflects this ancient presence; foeniculum means little hay in Latin, a reference to its slender, grass-like flowering stalks. During the Middle Ages, Europeans hung fennel bundles above doorways, believing the plant warded off evil spirits and witchcraft. The Saxon people included fennel among their nine sacred herbs.
Its journey eastward brought it to India and China, where Ayurvedic and traditional Chinese medicine incorporated it for digestive and respiratory purposes. In perfumery, fennel oil emerged as a distinct aromatic material during the 19th century expansion of natural fragrance ingredients, valued for its ability to add fresh, green lift without the heaviness of some other aromatics.
