Chaste tree fruit extract, also known as Vitex agnus-castus fruit extract, is a herbal product traditionally used for premenstrual symptoms such as breast tenderness, irritability, mood changes, bloating or discomfort before menstruation. It is thought to act on the hypothalamic-pituitary axis and may influence prolactin levels. It is not an immediate symptom reliever.
It is taken by mouth, usually daily, according to the product leaflet. The effect develops gradually and may require several menstrual cycles. It is not suitable for treating abnormal bleeding, severe pelvic pain, infertility or hormonal disorders without diagnosis. If periods become irregular, very heavy or stop, medical assessment is needed rather than continuing self-treatment.
Possible side effects include nausea, headache, dizziness, acne, itching, skin rash, digestive upset or changes in the menstrual cycle. The product may theoretically interact with dopaminergic or anti-dopaminergic medicines, hormonal contraception or hormone therapy, so it is important to tell a doctor or pharmacist what other medicines are being used.
Pregnant or breastfeeding women should not use it unless advised by a healthcare professional. People with pituitary tumours, oestrogen-sensitive cancer or fertility treatment should consult a doctor before use. Stop the product and seek help if allergic reactions, severe rash, intense headache or important changes in general condition occur.
