Chasteberry: Usefulness and Safety
NCCIH
Controls low-confidence framing and pregnancy, breastfeeding, hormone-sensitive-condition, and medication cautions.
Reviewed guidance
Some properly characterized oral chasteberry extracts may reduce overall PMS symptoms over several menstrual cycles, but the evidence base is small and product-specific.
Ongoing reduction of typical premenstrual symptom burden in adults using a properly characterized oral chasteberry fruit extract comparable to products studied in randomized trials; not a claim for tea, whole berries, tinctures, powders, or culinary preparations.
How to use it: Use only a labeled oral chasteberry product with a clearly characterized extract; trial evidence generally assessed daily use across about three menstrual cycles. Track symptoms prospectively and reassess benefit rather than continuing indefinitely without review.
Avoid during pregnancy or breastfeeding and use caution with hormone-sensitive conditions. Review use with a clinician or pharmacist if taking medicines, especially hormonal therapies. Stop and seek advice for significant adverse effects or new abnormal bleeding.
Get medical care for symptoms that are severe, last longer than expected, get worse, or otherwise concern you.
Practical ways to use the ingredient may not provide the same form or amount discussed in the evidence.
