Fenugreek

Botanical name: Trigonella foenum-graecum

Parts used and where grown

Although originally from southeastern Europe and western Asia, fenugreek grows today in many parts of the world, including India, northern Africa, and the United States. The seeds of fenugreek are used medicinally.

Fenugreek has been used in connection with the following conditions (refer to the individual health concern for complete information):

Rating	Health Concerns
	High cholesterol Type 2 diabetes
	Atherosclerosis High triglycerides
	Constipation Type 1 diabetes
Reliable and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit. For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support and/or minimal health benefit.

Historical or traditional use (may or may not be supported by scientific studies)

A wide range of uses were found for fenugreek in ancient times. Medicinally it was used for the treatment of wounds, abscesses, arthritis, bronchitis, and digestive problems. Traditional Chinese herbalists used it for kidney problems and conditions affecting the male reproductive tract.¹ Fenugreek was, and remains, a food and a spice commonly eaten in many parts of the world.

Active constituents

Fenugreek seeds contain alkaloids (mainly trigonelline) and protein high in lysine and L-tryptophan. Its steroidal saponins (diosgenin, yamogenin, tigogenin, and neotigogenin) and mucilaginous fibre are thought to account for many of the beneficial effects of fenugreek. The steroidal saponins are thought to inhibit cholesterol absorption and synthesis,² while the fibre may help lower blood sugar levels.³ One human study found that fenugreek can help lower cholesterol and blood sugar levels in people with moderate atherosclerosis and non-insulin-dependent (type 2) diabetes.⁴ Preliminary and double-blind trials have found that fenugreek helps improve blood sugar control in patients with insulin-dependent (type 1) and non-insulin-dependent (type 2) diabetes.⁵ ⁶ ⁷ Double-blind trials have shown that fenugreek lowers elevated cholesterol and triglyceride levels in the blood,⁸ ⁹ This has also been found in a controlled clinical trial with diabetic patients with elevated cholesterol.¹⁰ Generally, fenugreek does not lower HDL (“good”) cholesterol levels.

How much is usually taken?

Due to the somewhat bitter taste of fenugreek seeds, de-bitterized seeds or encapsulated products are preferred. The German Commission E monograph recommends a daily intake of 6 grams.¹¹ The typical range of intake for diabetes or cholesterol-lowering is 5–30 grams with each meal or 15–90 grams all at once with one meal. As a tincture, 3–4 ml of fenugreek can be taken up to three times per day.

Are there any side effects or interactions?

Use of more than 100 grams of fenugreek seeds daily can cause intestinal upset and nausea. Otherwise, fenugreek is extremely safe. Due to the potential uterine stimulating properties of fenugreek, which may cause miscarriages, fenugreek should not be used during pregnancy.¹²

Are there any drug interactions?
Certain medicines may interact with fenugreek. Refer to drug interactions for a list of those medicines.
