Fenugreek
A clover-like plant whose maple-scented seeds are a common spice and one of the oldest medicinal plants still in use. Evidence for blood sugar, menstrual cramps and milk supply is weak or mixed, and it is not safe in pregnancy beyond food amounts.
Traditional use
Native to the Mediterranean, southern Europe and western Asia and used as a medicine for about 6,000 years, in Europe as well as India. In Indian medicine the seeds were used to encourage breast milk and in many folk traditions for digestion and hair loss; in India the leaves are also eaten as a vegetable. Dutt's 1877 compilation from Sanskrit medical works records that Hindu physicians made sweet confections built on the seed (methi modaka) for poor appetite, for diarrhea after childbirth and for rheumatism. Today the seed is sold for diabetes, menstrual cramps and breastfeeding.

What studies show
- Insufficient
Blood sugar in type 2 diabetes: research suggests fenugreek may help lower blood sugar, but many studies were not high quality, and NCCIH says there is not enough high-quality evidence to know whether it is useful.
- Insufficient
Menstrual cramps: only a few studies, of low quality; the effect is uncertain.
- Limited
Breast milk supply: a few studies have mixed results. A 2020 Cochrane review was very uncertain whether fenugreek improves milk volume or the baby's weight.
Be careful of
Cautions
- PregnancyNot safe in pregnancy in amounts greater than those in food; its use has been linked to a higher risk of birth defects in animals and people. Little is known about amounts larger than food while breastfeeding.
- AmountSafe in food amounts for adults and children, and possibly safe for adults in larger amounts. Large doses may cause a harmful drop in blood sugar.
- AllergyCan cause allergic reactions, including serious ones, with facial swelling, wheezing and dizziness.
- InteractionBecause of its high fiber and other effects, it could interact with medicines, especially in high doses with blood thinners such as warfarin or antiplatelet drugs, and with diabetes medicine.
- NoteCommon side effects are diarrhea, nausea, bloating and gas. Mothers taking it have reported urine that smells like maple syrup. LiverTox (NIH) rates it an unlikely cause of liver injury.
- Ask a clinicianTalk with a clinician or pharmacist before using this if you take prescription medicines, are pregnant or breastfeeding, or are giving it to a child.
From the old books
What herbals and dispensaries of the past printed. History, in their words.
“The Trigonella Fœnum-græcum is extensively cultivated in many parts of India. Its seeds are used as a condiment and its aromatic leaves, as a pot-herb. Fenugreek seeds are considered carminative, tonic and aphrodisiac. Several confections made with this article are described under the names of Methi modaka, Svalpa methi modaka etc., and are recommended for use in dyspepsia with loss of appetite, in the diarrhœa of puerperal women and in rheumatism.”
“The young plants are always to be found in the vegetable markets, and are most esteemed when only the two seed leaves are formed; they are boiled and afterwards fried in butter, the taste is strongly bitter, and disagreeable to those who have not become accustomed to it”
