Fennel is a popular vegetable, spice, and flavoring, as well as an ingredient in traditional medicines. It is one of the key flavorings in absinthe. Fennel contains an anise-flavored compound called anethole, which is a potent antimicrobial against bacteria, yeast, and fungi. A lab study has shown anethole to be effective against some kinds of intestinal worms. Anethole may have some analgesic, or painreducing, effects and some anti-convulsant effects as well. Anethole also acts as a phytoestrogen.Nutritional Facts
