Bloating, gas, diarrhea, upset stomach and a maple syrup odor of the urine are possible side effects of large doses of fenugreek, according to WebMD. The herb may also lower blood sugar. In people who are allergic to it, fenugreek can cause nasal congestion, coughing, wheezing and facial swelling.

Fenugreek can cause early labor in pregnant women, and some children who have consumed fenugreek tea have lost consciousness, reports WebMD. Fenugreek can react with medications that treat clotting disorders and diabetes, notes Healthline. Diabetics who ingest fenugreek may need to reduce their dosages of diabetes medications to avoid blood sugar that is too low.

Fenugreek seeds have been used medicinally and in cooking in ancient Egypt, the Middle East and South Asia, states Healthline. In the past, people used it to treat digestive issues, arthritis, kidney problems and symptoms of menopause. People also used it to induce childbirth and aid in breastfeeding issues. As of 2015, people use fenugreek to treat appetite loss, diabetes, eczema and high cholesterol.

Doses range from 5 to 30 grams per day, but anyone considering using fenugreek should check with a doctor first, cautions Healthline. To take fenugreek, people often prepare it as a tea, sprinkle it on yogurt, or use it as an ingredient in certain recipes, such as curries.
