What is fennel?

Fennel is crunchy, slightly sweet, and delicious in popular Mediterranean cuisine. Though often associated with Italian cooking, make certain to add this to your choice of fresh veggies from the fall through early spring when it’s easily available and at its very best. Fennel is still among the very widely used medicinal plants, being used for digestive and eye health.  

The perennial plant is native to the Mediterranian area but has become widely available worldwide. Fennel is made up of a white or pale green bulb where closely superimposed stalks are organized. The stalks with green leaves support blossoms that grow and create fennel seeds. The plants’ bulbs, stalk, leaves, and seeds are all edible. Fennel is closely related to carrots, dill, parsley, and coriander as part of the Umbelliferae family. The advantages of fennel tea are incredibly similar to those derived from fennel seeds.

Fennel oil is used for flavor in foods and drinks, soaps, and certain laxatives.

The most interesting phytonutrient chemical in fennel, however, might be anethole or the main part of its volatile oil. It has been shown to decrease inflammation and to help prevent the incidence of cancer. Researchers also have suggested a biological mechanism that may explain these anti-inflammatory and anticancer effects. The volatile oil has also been proven to have the ability to protect the liver of experimental animals from toxic chemical harm.

Vitamin C and Immune Support: Along with its unusual phytonutrients, the fennel bulb is an exceptional source of vitamin C. Vitamin C is the body’s main water-soluble antioxidant, able to neutralize free radicals in most aqueous surroundings of the body. These free radicals may cause cellular damage that leads to pain and joint deterioration in conditions like rheumatoid arthritis and osteoarthritis. The vitamin C in the fennel bulb is antimicrobial and required for a smooth-running immune system.

Fiber, Folate, and Potassium for Heart and Colon Health: As an excellent source of fiber, a fennel bulb might help to reduce elevated cholesterol levels. And because fiber eliminates carcinogenic toxins in the colon, the fennel bulb may help prevent colon cancer.
