The health benefits of fennel include relief from anemia, indigestion, flatulence, constipation, colic, diarrhea, respiratory disorders, and menstrual disorders. It also aids in eye care. Fennel, which has the scientific name Foeniculum vulgare miller, or its essence, is widely used around the world in mouth fresheners, toothpaste, desserts, antacids, and in various culinary applications.
It originated in the Mediterranean region and has many culinary and medicinal uses. It has not been spread and naturalized as an herb around the world, but still primarily grows in coastal climates and on riverbanks. It is also one of the main components of the alcohol absinthe, although the plant does not have hallucinogenic properties.
Apart from the uses of fennel already mentioned, there are numerous medicinal uses and health benefits, mainly due to the components of its essential oils, which are summarized below.
Health Benefits of Fennel
Health benefits of fennel include:
Iron and histidine, an amino acid found in fennel, are both helpful in the treatment of anemia. Whereas iron is the chief constituent of hemoglobin, histidine stimulates the production of hemoglobin and also helps in the formation of various other components of the blood.
Some of the components in the fennel essential oil are stimulants and they stimulate secretion of digestive and gastric juices while reducing inflammation in the stomach and intestines, and facilitating proper absorption of nutrients from the food. Furthermore, it can eliminate constipation and protect the body from a wide range of intestinal troubles that can stem from being blocked up. It also has anti-acidic (basic) properties and is extensively used in antacid preparations. In culinary applications, it is also used as the main ingredient in many appetizers.
Fennel is very popular as an antiflatulent, due to the carminative properties of the aspartic acid found in it. Its extract can be used by everyone, from infants to the elderly, as a way to reduce flatulence and to expel excess gas from the stomach. It is commonly used in medicines to reduce symptoms of non-ulcer dyspepsia and flatulence in infants and young children.
Fennel seeds, particularly in powdered form, can act as a laxative. The roughage helps clear the bowels, whereas its stimulating effect helps maintain the proper peristaltic motion of the intestines, thereby helping promote proper excretion through the stimulation of gastric juices and bile production. Fennel is also commonly found in medicines that treat abdominal pain, diarrhea, irritable bowel syndrome (IBS), and other intestinal issues.
Reduces Heart Diseases
Fennel is a great source of fiber, as mentioned above, but besides the advantages to digestion that fiber provides, it also helps maintain healthy levels of cholesterol in the bloodstream. This means that it can stimulate the elimination damaging LDL or bad cholesterol, which is a major factor in heart diseases, atherosclerosis, and strokes.
The raw vegetable itself hasn’t been extensively studied with regards to cancer protection, but the fennel seed extract has been, and the findings regarding cancer protection are quite impressive. It shows that the extract can not only inhibit the growth of tumors, thanks to its concentrations of flavonoids, alkaloids, and phenols but that it can even be somewhat chemo-protective against the harmful effects of radiation during cancer treatment. Fennel seed extract has been found to prevent various breast cancer and liver cancer strains.
Regulates Blood Pressure
Fennel is a very rich source of potassium, which is an essential nutrient in our bodies and is vital for a number of important processes. One of the attributes of potassium is its quality as a vasodilator, which means that it relaxes the tension of blood vessels, thereby reducing blood pressure. High blood pressure is connected to a wide range of health issues, including heart attack, stroke, and atherosclerosis. Also, for diabetics, blood pressure issues can make management of their insulin and glucose levels very difficult and can be the cause of many potentially lethal complications. A cup of fennel bulb in your daily diet will pump you full of potassium and all the benefits that come along with it.
Improves Brain Function
Potassium, found in high levels in fennel bulbs and seeds, is an electrolyte, which means that it facilitates increased electrical conduction throughout the body. This includes connections within the brain, which is a veritable switchboard of electric currents. Potassium can help increase brain function and cognitive abilities through this quality. Also, fennel is a vasodilator, which means more oxygen reaches the brain and neural activity can work at optimal functionality.
Fennel is helpful in curing diarrhea if it is caused by bacterial infections because some components such as anethol and cineole have disinfectant and antibacterial properties. Some amino acids, such as histidine, can aid in digestion and the proper functioning of the digestive system, thereby helping to eliminate diarrhea due to indigestion. Fennel has long been used by indigenous cultures as a way to eliminate diarrhea.
Polymeric and heavy molecules are useful in the treatment of renal colic. Such polymers, also called phytoestrogens, are found in anethole, a component of the fennel essential oil. This makes it quite helpful in the treatment of renal colic. Fennel has certain antispasmodic qualities which also help it relax smooth muscles and reduce the discomfort associated with the condition.
1 cup of fennel bulb contains almost 20% of the daily requirement of vitamin C, which makes it quite a rich source of this beneficial element of our diet. Vitamin C improves general immune system health, produces and repairs skin tissue, helps form collagen, and also protects the blood vessel walls as an antioxidant against the harmful effects of free radicals that can frequently lead to heart diseases.
Fennel is also an emmenagogue, meaning that it eases and regulates menstruation by properly regulating hormonal action in the body. Furthermore, fennel is used in a number of products to reduce the effects of PMS, and it is also used traditionally as a soothing pain reliever and relaxing agent for menopausal women.
Promotes Breast Enlargement
The flavonoids present in fennel seeds increase the amount of estrogen thereby acting as a stimulant and tonic. Fennel seeds help increase the size of the breasts as they increase the formation of new cells and tissues in the breast.
Using fennel in food helps protect the eyes from inflammation and also help reduce disorders related to premature aging and macular degeneration. This is due to the high abundance of antioxidants (vitamin C and amino acids like arginine are very beneficial for rejuvenation of tissues and the prevention of aging), detoxifiers and stimulants. They are more specifically found in fennel essential oil, as well as minerals like cobalt and magnesium. Finally, the juice of its leaves and the plant itself can be externally applied to the eyes to reduce irritation and eye fatigue.
Fennel is also a rich source of flavonoids, which are very useful in protecting against pigment cells dying due to oxidative-stress-induced death. By protecting against this destruction of the pigment cells, fennel can safely be classified as effective in eye health for numerous reasons.
Treats Respiratory Disorders
Fennel is useful in respiratory disorders such as congestion, bronchitis, and cough due to the presence of cineole and anethol, which are expectorant in nature, among their many other virtues. Fennel seeds and powder can help break up phlegm and prompt loosening of the toxins and buildup of the throat and nasal passages for elimination from the body to ensure quick recovery from respiratory conditions.
Other Benefits & Uses
Fennel is a diuretic, which means that it increases the amount and frequency of urination, thereby helping the removal of toxic substances from the body and helping in rheumatism and swelling. It also increases the production and secretion of milk in lactating mothers and since this milk contains some properties of fennel, it is an anti-flatulent for the baby as well. It strengthens hair, prevents hair loss, relaxes the body, sharpens memory, and has a marvelous cooling effect in summer. This can be achieved if the pale, greenish-yellow water, in which it is soaked, is ingested with a bit of sugar and black salt.
Words of Caution: You must remember that there are two sides to any story and too much of anything is harmful. Certain components of the fennel essential oil such as anethol, and a few other chemicals present in the plant itself can be dangerous if ingested in too large a quantity. You must remember that the compounds which can kill bacteria and microbes in low doses can be harmful to you too. Excess use of fennel can cause difficulty breathing, increased palpitations, irregular heartbeat, and various neural problems.
