Fenugreek Can be Useful for Digestive Problems

Fenugreek seeds have been used for loss of appetite and anorexia due to their ability to increase appetite and improve nutrient absorption and digestion.

Fenugreek seeds consist, up to 50%, of mucus-containing fibers that add a protective layer on the intestinal membranes and can give relief from ulcers, heartburn and irritation and inflammation of the stomach and intestine.

The fiber may also help relieve constipation because it softens the bowel contents and at the same time it is considered a useful herbal remedy for diarrhea as the seeds husks absorb water resulting in a bulkier stool.

Fenugreek May Help Improve Lactation During Breastfeeding

Fenugreek seeds contain hormone precursors (phytoestrogens) that are thought to increase milk production in nursing mothers, and the herb is often used traditionally for insufficient lactation.

Several studies have been done to confirm this traditional application.

While few studies have show fenugreek to be effective in increasing the production of breastmilk, others have found it to have hardly any effect in increasing lactation.

Also, it has a reputation for enlarging breast tissue and is widely used in natural breast enhancement products.

Fenugreek seeds contain diosgenin, a substance similar to the female sex hormone estrogen, and other plant phytoestrogens which are thought to promote breast growth in women.

Diosgenin is used extensively in the pharmaceutical industry, including in the production of cortisone preparations and oral contraceptives. However, no scientific proof can confirm that fenugreek seeds can enlarge breast tissue and more studies are needed.

It may be useful as an herbal remedy to minimize the symptoms of menopause, and it is thought to be helpful for painful PMS.

May Increase Libido

It has been used through the ages to heighten sexual desire both in men and women and has been used for premature ejaculation and impotence.

The herb lowers blood cholesterol levels, improves blood circulation and can, therefore, increase blood flow to the penis.

May be Beneficial for Respiratory Ailments

Tea made from the seeds has been used for a long time to treat lung diseases such as bronchitis and asthma.

It is also considered a good herbal remedy for a sore throat and coughs. A mucus-like substance found in the seeds has soothing properties by forming a barrier that protects the mucous membranes of the respiratory tract against mechanical and chemical irritation.

External Uses

Fenugreek has been used for skin irritation, such as ulcers, boils, eczema, dandruff, and cellulite.

Some other external traditional applications of the herb have been as a healing agent, to treat infected wounds, and due to its anti-inflammatory properties it has also been used to treat hemorrhoids, gout, rheumatism, muscle pain, treat halitosis and aching joints.

Other Medicinal Uses of Fenugreek Seeds

In modern times, the interest in the herb in the Western world has primarily been because of the alkaloid trigonelline found in the plant, which has been shown to have some potential in the treatment of liver and cervical cancer.

It has been used as a traditional herbal remedy to promote hair growth both in women and men.

In Saudi Arabia, the leaves and seeds are used as a remedy for kidney stones. In one animal study it was noted that when rats were given a dose of fenugreek daily for a month, they had a significant reduction in the amount of calcium that was deposited in the kidneys, which can support this folk medicine usage.

The leaves of fenugreek contain the substance choline, and the seeds are an excellent source of the antioxidant beta-carotene.

Both substances may be helpful for memory loss, Alzheimer’s and slow down the aging process. Additionally, choline can be used to treat arteriosclerosis because of the ability to remove accumulated fat (cholesterol) from the artery’s walls.

The seeds might be effective against roundworms, and they contain some chemicals that have insect repellent properties and can be used as an insecticide.

Active Substances and Constituents

Fenugreek seeds contain 45-60% carbohydrates, 20-30% proteins (high in lysine and tryptophan), 5-10% fatty oil (lipids), pyridine-type alkaloids (predominantly trigonelline, choline, gentianin and carpaine), flavonoids (apigenin, luteolin, orientin, quercetin, vitexin)

Fenugreek also contains glycosides that form steroidal sapogenins by hydrolysis (diosgenin, yamogenin, tigogenin, neotigogenin), bitters, coumarins, cholesterol, sitosterol, vitamins A, B1 and C, minerals (including calcium, phosphorus, and iron) and 0.015% of essential oil.

The substance diosgenin, which is also found in wild yam (Dioscorea villosa), is used in the modern pharmaceutical industry to manufacture, e.g., cortisone preparations and oral contraceptives.

Today fenugreek is widely grown in Argentina, France, India, North Africa, England, and the United States. Nowadays the seeds and fresh leaf shoots come only from cultivated plants.


Fenugreek has hairy, green and round stems with few leaf stalks and can grow to be about two feet tall (60 cm). Fenugreek has trifoliate leaves and blooms white flowers tinged with violet in the early summer.

The flowers develop into long brown pods which contain the fenugreek seeds. The seeds give strong unique aroma, not unlike maple syrup with a hint of celery.
