Food therapy - Fennel as antioxidants

Fennel is a species of Foeniculum Vulgare, belonging to the family Apiaceae (Umbelliferae), and native to the shores of the Mediterranean. It is now widely cultivated all around the globe to use as food and herb.

Free radicals are atoms, molecules, or ions with unpaired electrons through chemical bonds with other atoms or molecules during a chemical reaction. They may have positive, negative or zero charge. The unpaired electrons cause radicals to be highly chemically reactive in the human body, leading to aging and cancers.
The comparison of commercial essential oils (EO) containing Citrus aurantium, C. limon, Cupressus sempervirens, Eucalyptus globulus, Foeniculum vulgare and Thymus vulgaris showed that F. vulgare EOs is effective against lipid peroxidation(3). In support of the above, the University of Wyoming suggested that Fennel oils might have higher antioxidant capacity in distillation time (DT) depend-manner. DT can be used to obtain fennel essential oil with differential composition(4).
Some researchers suggested that the potent antioxidant properties of medicinal plants may depend on variety conditions such as environmental conditions, climatic and seasonal variations, geographical regions of growth, degree of ripeness, growing practices, and many other factors such as postharvest treatment and processing(5).
