History/Folklore: One of the nine plants invoked in the pagan, Anglo-Saxon Nine Herbs Charm recorded in the 10th century. Ancient Romans regarded fennel as the herb of sight with root extract often used in tonics to clear cloudy eyes. In 1611, Italian herbalist Pierandrea Mattioli filled several pages of his folio on herbal formula remedies based on his native plant Fennel for urinary, bronchial, and digestive complaints. Considered one of the four opening roots (with Asparagus, Parsley, and Celery) by herbalist Galen. In the 17th century, William Coles wrote that fennel was used “for those that are grown fat, to abate their unwieldiness and cause them to grow more gaunt and lank.” (As drinking a cup of fennel tea before a meal can take the edge off your appetite.) Fresh stems can be eaten like celery.

Key Constituents:

Anethole (same compound found in anise and star anise, hence the similar taste, though not as strong), Fenchone, a-Pinene, camphene, Dipentene, a-Phallandrene, Anise aldehyde, Anisic acid, estragole, 7-hydroxycoumarin, Vitamin C and Potassium.

Along with similar tasting anise, fennel is one of the key ingredients in absinthe.
