Fenugreek (trigonella foenum-graecum)

Fenugreek (trigonella foenum-graecum)

Help for High Cholesterol

Fast facts: minimizes symptoms of menopause, relieves constipation, controls diabetes, reduces cholesterol, soothes sore throat pain and coughs, eases minor indigestion, relieves diarrhea

From ancient times through the late 19th century, fenugreek played a major role in herbal healing. Then it fell by the wayside. Now things are once again looking up for the herb whose taste is an odd combination of bitter celery and maple syrup. Modern scientific research has found that fenugreek can help reduce cholesterol levels, control diabetes and minimize the symptoms of menopause.

The ancient Greeks fed this herb to horses and cattle. The Romans then started using it, too, calling it “Greek hay.” (In Latin, “Greek hay” is foenum-graecum, and that evolved into “fenugreek.”) As fenugreek spread around the ancient Mediterranean, physicians learned that its seeds, like many seeds, contain a gummy substance called mucilage. Mixed with water, mucilage expands and becomes a gelatinous soother for irritated tissues.

In India, the herb was incorporated into curry blends. India’s traditional Ayurvedic physicians prescribed it to nursing mothers to increase their milk. In American folk medicine, fenugreek was considered a potent menstruation promoter. It became a key ingredient in Lydia E. Pinkham’s Vegetable Compound — one of 19th-century America’s most popular patent medicines for “female weakness” (menstrual discomforts). Today, fenugreek is most widely used in the United States as a source of imitation maple flavor. But this may change as its medicinal value becomes better known.

Almost a century after Lydia Pinkham’s death, scientists have confirmed that fenugreek seeds contain chemicals (diosgenin and estrogenic isoflavones) similar to the female sex hormone estrogen. Loss of estrogen causes menopausal symptoms, so adding fenugreek to the diet might help minimize them. Estrogen can also cause breast swelling. “One woman told me her breasts grew larger after she started eating fenugreek sprouts,” says James A. Duke, Ph.D., a botanist retired from the U.S. Department of Agriculture and author of The CRC Handbook of Medicinal Herbs.

Cholesterol buster … and more Several studies have shown that fenugreek reduces cholesterol in laboratory animals, and Indian researchers have shown the same effect in people with high cholesterol levels. The people in one Indian study added about four ounces a day of powdered fenugreek seeds to their diet for 20 days. During that time their total cholesterol levels and their levels of low-density lipoprotein (LDL, or “bad”) cholesterol fell significantly. At the same time their high-density lipoprotein (HDL, or “good”) cholesterol levels remained unaffected. “There’s no question that fenugreek reduces cholesterol,” says Daniel B. Mowrey, Ph.D., director of the American Phytotherapy Research Laboratory in Salt Lake City, Utah, and author of The Scientific Validation of Herbal Medicine. Fenugreek also “has great promise in alleviating Type II (non- insulin-dependent) diabetes,” says Dr. Duke. And according to one study, it may also help people with Type I (insulin-dependent) diabetes. For ten days, Indian researchers added about four ounces of powdered fenugreek seeds a day to the diets of people with Type I diabetes, which requires daily insulin injections. The injections, however, did not entirely eliminate a key sign of the illness, sugar in their urine. With fenugreek added to their diet, their urinary sugar levels fell by 54 percent.

Fenugreek’s soothing mucilage can also help relieve sore throat pain, cough and minor indigestion. “Because its mucilage expands in the gut, it also adds bulk to the stool,” says Bernie Olin, Pharm.D., editor of The Lawrence Review of Natural Products, a St. Louis-based newsletter that summarizes scientific research on the medicinal value of herbs. “As a result, it can help treat constipation and diarrhea.”

To make a medicinal tea, gently boil two teaspoons of mashed seeds per cup of water, then simmer for ten minutes. Drink up to three cups a day. To improve the flavor, you can add sugar, honey, lemon, anise or peppermint.

Fenugreek is considered safe. But several of the conditions it helps — diabetes, elevated cholesterol and menopausal symptoms — require professional care. If you’d like to use this herb in addition to standard therapies, consult your physician. *These statements have not been evaluated by the Food and Drug Administration.

Fennel (Foeniculum vulgare)

Fennel (Foeniculum vulgare)

Fennel

Fennel (Foeniculum vulgare) in the parsley family (Apiaceae) is a tall perennial native to the Mediterranean region, now cultivated worldwide as an annual or perennial.1 Two varieties of fennel are often used, common or bitter fennel and sweet fennel.1

History and Traditional Use

The modern uses of fennel in the United States and Germany stem from its traditional use in Greek medicine by Hippocrates and later by Dioscorides.2 Pliny the Elder recommended it for improving eyesight.3 Traditionally, fennel fruit and oil were used to relieve gas, to treat stomach trouble, and for inflammation of the upper respiratory tract.1 Traditional Chinese medicine also utilizes fennel to treat cholera, backache, bedwetting, and severe snakebites.1 The oil can prevent pathogenic fungi from infecting stored fruits and vegetables.3 Tea made from crushed fennel seeds has been used as an eyewash.3

Modern Medicinal Use

The dried ripe fruit (or seed) and the oil that is obtained by steam distillation have similar medicinal applications. Both fennel seed and oil are approved by the German Commission E for stomach spasms, fullness, and gas, and for inflammation of the upper respiratory tract.4 In Europe, fennel syrup is approved for inflammation of the upper respiratory tract in children.5 The current Ayurvedic pharmacopoeia (plants used in traditional Indian medicine) recommends fennel for anorexia, gassy colic in children, and dyspepsia (painful digestion).6 The Chinese pharmacopoeia acknowledges the use of fennel in vomiting, diarrhea, and severe menstrual cramps.7 Fennel oil contains compounds with estrogenic effects such as stimulating lactation (milk flow) and menstruation..8

Modern Consumer Use

Both the bitter and sweet fennel oils are used as fragrance components in creams, lotions, perfumes, soaps, and detergents.1 Fennel fruit can also be found in herbal teas or honey syrup. Sweet fennel is used in a variety of food and beverage products, including alcoholic drinks, meats, baked goods, processed vegetables,1 pickles, and candies.3

False Unicorn (Chamaelirium luteum)

False Unicorn (Chamaelirium luteum)

Parts used and where grown: False unicorn is native to Mississippi and continues to grow primarily in the southern parts of the United States. The roots of false unicorn contain the greatest amounts of the active constituents.

In what conditions might false unicorn root be supportive?

Â¥ amenorrhea (lack of menstruation)

Â¥ menorrhagia (heavy menstruation)

Â¥ painful menstruation (dysmenorrhea)

Â¥ premenstrual syndrome

Historical or traditional use: The medicinal use of false unicorn root is based in Native American tradition, where it was recommended for a large number of women’s health conditions, including lack of menstruation (amenorrhea), painful menstruation, and other irregularities of menstruation, as well as to prevent miscarriages.1 It was also an important remedy for morning sickness.

Active constituents: Steroidal saponins are generally credited with providing false unicorn rootÕs activity.2 Modern investigations have not confirmed this, and there is no research yet about the medical applications of this herb.

How much should I take? Generally, false unicorn root is taken as a tincture in the amount of 2&endash;4 ml per day. It is almost always taken in combination with other herbs supportive of the female reproductive organs, particularly vitex (Vitex agnus-castus).

Are there any side effects or interactions? No adverse effects have been reported with the use of false unicorn. Its long history of use in pregnant women suggests it may be safe for these individuals, but no studies have confirmed or denied it.

Eyebright (Euphrasia officinalis)

Eyebright (Euphrasia officinalis)

Parts used and where grown: Euphrasia officinalis has been used to refer to a vast genus containing over 450 species. European wild plants grow in meadows, pastures, and grassy places in Bulgaria, Hungary, and the former Yugoslavia. Eyebright is also grown commercially in Europe. The plant flowers in late summer and autumn. The whole herb is used in commercial preparations.

In what conditions might eyebright be supportive?

Â¥ conjunctivitis/blepharitis

Â¥ irritated eyes

Historical or traditional use: Eyebright was and continues to be used primarily as a poultice for the topical treatment of eye inflammations, including blepharitis, conjunctivitis, and sties. A compress made from a decoction of eyebright can give rapid relief from redness, swelling, and visual disturbances in acute and subacute eye infections.1 A tea is usually given internally along with the topical treatment. It has also been used for the treatment of eye fatigue and disturbances of vision. In addition, herbalists have recommended eyebright for problems of the respiratory tract, including sinus infections, coughs, and sore throat.2

Active constituents: Eyebright is high in iridoid glycosides, flavonoids, and tannins.3 The plant has astringent properties that probably account for its usefulness as a topical treatment for inflammatory states and its ability to reduce mucous drainage.

How much should I take? Traditional herbal texts recommend a compress made with 15 grams of the dried herb combined with 0.5 liter of water and boiled for ten minutes. The undiluted liquid is used as a compress after cooling. This was commonly combined with antimicrobial herbs, such as goldenseal. The current German monograph on eyebright does not support this application, due to potential bacterial concerns.4

Internally, eyebright tea, made using the same formula above, can be drunk in the amount of two to three cups per day. Dried herb, as 2-4 grams three times per day, may be taken. The tincture is typically taken in 2-6 ml three times per day.

Are there any side effects or interactions? Due to limited information on the active constituents in eyebright and the need for sterility in substances used topically in the eyes, the traditional use of eyebright as a topical compress currently cannot be recommended. Used internally at the amounts listed above, eyebright is generally safe. However, its safety during pregnancy and lactation has not been proven.
