Fennel (Foeniculum vulgare) seeds are a premier carminative medicine rich in volatile essential oils, predominantly trans-anethole and fenchone. Trans-anethole acts as a powerful smooth-muscle relaxant in the gastrointestinal tract, relieving painful intestinal cramps, expelling trapped gas, and relaxing digestive spasms. The seeds also contain phytoestrogens that stimulate breast milk production and ease colic in breastfed infants.
