Fenugreek may be effective for improving blood sugar control, reducing menstrual pain, improving sexual arousal and drive. There is limited evidence to support its other uses.
Side effects are mainly gastrointestinal and can include abdominal pain, bloating, gas, diarrhea, nausea, and upset stomach. It may also lower blood sugar levels.
Fenugreek may interact with the following:
- anticoagulants (e.g., apixaban, warfarin)
- antiplatelets (e.g., acetylsalicylic acid (ASA), clopidogrel)
- diabetes medications (e.g., metformin, sitagliptin)
- metoprolol
- theophylline
Pregnant women should use caution as this product has been used historically to induce labour. People with diabetes should ask their doctor before taking fenugreek due to the risk of low blood sugar episodes (hypoglycemia).
Do not take fenugreek if you are allergic to other Fabaceae plants, including soybeans, chickpeas, peanuts, green peas, and other legumes.
Stop taking fenugreek at least 2 weeks before surgery.
Before taking any new medications, including natural health products, speak to your physician, pharmacist, or other health care provider. Tell your health care provider about any natural health products you may be taking.
