Fenugreek
Fenugreek seeds are
a rich source of the polysaccharide galactomannan. They are also a
source of saponins such as diosgenin, yamogenin, gitogenin, tigogenin,
and neotigogens. Other bioactive constituents of fenugreek include
mucilage, volatile oils, and alkaloids such as choline and trigonelline.
A side effect of
consuming even small amounts of fenugreek (even as just an infusion in
water) is a maple syrup or curry smell in the eater's sweat and urine,
which is caused by the potent aroma compound sotolone. Fenugreek is
frequently used in the production of flavoring for artificial syrups.
The taste of toasted fenugreek is additionally based on substituted
pyrazines, as is cumin. By itself, it has a somewhat bitter taste.
Fenugreek is mainly
used as a digestive aid. Fenugreek seed is widely used as a
galactagogue (milk producing agent) by nursing mothers to increase
inadequate breast milk supply. Studies have shown that fenugreek is a
potent stimulator of breastmilk production and its use was associated
with increases in milk production of as much as 900%. [3] It can be
found in capsule form in many health food stores.[4]
Supplements of
fenugreek seeds were shown to lower serum cholesterol, triglyceride,
and low-density lipoprotein in human patients and experimental models
of hypercholesterolemia and hypertriglyceridemia (Basch et al., 2003).
Several human intervention trials demonstrated that the antidiabetic
effects of fenugreek seeds ameliorate most metabolic symptoms
associated with type-1 and type-2 diabetes in both humans and relevant
animal models (Basch et al., 2003; Srinivas, 2005). Fenugreek is
currently available commercially in encapsulated forms and is being
prescribed as dietary supplements for the control of
hypercholesterolemia and diabetes by practitioners of complementary and
alternative medicine.
In recent research,
fenugreek seeds were experimentally shown to protect against cancers of
the breast (Amin et al., 2005) and colon (Raju et al., 2006). The
hepatoprotective properties of fenugreek seeds have also been reported
in experimental models (Raju and Bird, 2006; Kaviarasan et al., 2006;
Thirunavukarrasu et al., 2003).
The name fenugreek
or foenum-graecum is from Latin for "Greek hay". Zohary and Hopf note
that it is not yet certain which wild strain of the genus Trigonella
gave rise to the domesticated fenugreek but believe it was brought into
cultivation in the Near East. Charred fenugreek seeds have been
recovered from Tell Halal, Iraq, (radiocarbon dating to 4000 BC) and
Bronze Age levels of Lachish, as well as desiccated seeds from the tomb
of Tutankhamen.[2] Cato the Elder lists fenugreek with clover and vetch
as crops grown to feed cattle (De Agri Cultura, 27).
Use
The rhombic yellow
to amber colored fenugreek seed, commonly called methi, is frequently
used in the preparation of pickles, curry powders, and pastes, and is
often encountered in the cuisine of the Indian subcontinent. The young
leaves and sprouts of fenugreek are eaten as greens, and the fresh or
dried leaves are used to flavor other dishes. The dried leaves (called
kasuri methi) have a bitter taste and a strong characteristic smell.
In India, fenugreek seeds are mixed with yogurt and used as a
conditioner for hair. It is one of the three ingredients of idli and
dosa (Tamil). It is also one of the ingredients in the making of
khakhra, a type of bread. It is used in injera/taita, a type of bread
unique to Ethiopian and Eritrean cuisine. The word for fenugreek in
Amharic is abesh, and the seed is reportedly also often used in
Ethiopia as a natural herbal medicine in the treatment of diabetes. It
is also sometimes used as an ingredient in the production of clarified
butter (Amharic: qibé, Ethiopian and Eritrean Tigrinya: tesme), which
is similar to Indian ghee. In Turkey, fenugreek gives its name, çemen,
to a hot paste used in pastirma. The same paste is used in Egypt for
the same purpose. The Arabic word hulba (Helba in Egypt) for the seed
resembles its Mandarin Chinese counterpart hu lu ba. In Yemen it is the
main condiment and an ingredient added to the national dish called
saltah. Fenugreek, or Şambélilé in Persian, is also one of four herbs
used for the Iranian recipe Ghormeh Sabzi.
In Egypt, fenugreek
seeds are prepared as tea, by being boiled then sweetened. This is a
popular winter drink served in coffee shops. In other parts of the
Middle East fenugreek is used in a variety of sweet confections. A cake
dessert known as Helba in the Islamic world is a tasty treat during
Islamic holidays. This is a semolina cake covered in sugar or
maple-like syrup, and sprinkled with fenugreek seeds on top.
Jews customarily
eat the fenugreek during the meal of the first and/or second night of
Rosh Hashana (The New Year). It is green and is similar to the verb (to
increase) in Hebrew, which symbolically signifies a prayer that their
merits will increase.
