Health Benefits of Fennel
The health benefits of fennel include relief from anemia, indigestion, flatulence, constipation, colic, diarrhea, respiratory disorders, menstrual disorders, and its benefits regarding eye care. Fennel, which has the scientific name Foeniculum Vulgare Miller, or its essence, is widely used around the world in mouth fresheners, toothpastes, desserts, antacids and in various culinary applications.
Apart from these uses of fennel, 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
Anemia: Iron and histidine, an amino acid found in fennel, are both helpful in treatment of anemia. Whereas iron is the chief constituent of hemoglobin, histidine stimulates production of hemoglobin and also helps in the formation of various other components of the blood.
Indigestion: It is a common practice, particularly on the Indian Subcontinent, to chew fennel seeds after meals. This is done to facilitate digestion and to eliminate bad breath.
Some of the components of the essential oils in fennel are stimulants and they stimulate secretion of digestive and gastric juices, while reducing inflammation of the stomach and intestines, and facilitating proper absorption of nutrients from the food. It also has antiacidic (basic) properties and is extensively used in antacid preparations. In culinary applications, it is also used as an ingredient of focal point of many appetizers.
Flatulence: Fennel is very popular as an antiflatulent, due to the carminative properties of the aspartic acid found in fennel. 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.
Constipation: 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.
Diarrhea: Fennel is helpful in curing diarrhea if it is caused by bacterial infection, because some components of the essential oil in fennel such as anetol 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.
Colic: 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 essential oil in fennel. This attribute of fennel makes it quite helpful in the treatment of Renal Colic.
Menstrual Disorders: Fennel is also an Emenagogue, meaning that it eases and regulates menstruation by properly regulating hormonal action in the body.
Eye Care: Using fennel in food helps protect the eyes from inflammation, as well as helping to 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 which are very beneficial for rejuvenation of tissues and the prevention of aging), detoxifiers and stimulants. They are more specifically in fennel essential oil, as well as minerals like cobalt and magnesium. Finally, the juice of fennel leaves and the plant itself can be externally applied on the eyes to reduce irritation and eye fatigue.
Respiratory Disorders: Fennel is useful in respiratory disorders such congestion, bronchitis, and cough due to the presence of Cineole and Anetol which are expectorant in nature, among their many other virtues.
Other Benefits: Fennel is 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. Fennel also increases 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 fennel is soaked, is ingested with a bit of sugar and black salt.
A Few Words of Caution: You must remember that there are two sides to any story and too much of anything is harmful. This is obviously true for fennel as well. Certain components of the fennel essential oil such as Anethol, and a few chemicals present in the plant itself, besides being beneficial, can be dangerous if ingested in too large of a quantity. You must remember that the compounds which can kill bacteria and microbes in low doses can be harmful for you too. Excess use of fennel can cause difficulty breathing, increased palpitations, irregular heart beat, and various neural problems.
