Overview:Fennel belongs to the family Umbelliferae. Fennel seed is commonly used as a food and spice around the world, especially in India where it is recognized for its digestive healing powers. The seed has many medicinal virtues and was used traditionally for alleviating digestive complaints, for stimulating milk flow in lactating mothers, externally as an eye lotion (decoction), and in functional visual disorders. A handful of fennel seeds have been used to treat heartburn for thousands of years. Fennel seed is recommended by many herbalists to prevent hormonal imbalances and treat menstrual difficulties (Amenorrhea). The German Pharmacopoeia recognizes fennel seed as a source of essential oils and bitters that aid digestion and treat dyspepsia, mild stomach cramps, bloating, and flatulence. The seed is also recommended as a taste enhancer, to counteract the mild cramps accompanying the use of laxatives, and to dissolve mucous in the upper respiratory tract. Fennel seed contains the compound creosol and up to 8,800 ppm of alpha-pinene, compounds that help to loosen bronchial secretions. The seed is also considered to be antimicrobial and antiseptic.
