Mechanism of Action

Acts on the hypothalamic–pituitary–ovarian axis by increasing dopamine activity, which reduces prolactin levels. This helps balance the ratio between oestrogen and progesterone, particularly benefiting those with low progesterone.

Modern Applications

Used for PMS, irregular periods, infertility due to luteal phase defect, hormonal acne, perimenopausal symptoms, and cyclic breast pain.

Recommended Dosage

Tincture: 2–5 ml/day in the morning; Capsules: 150–250 mg extract/day; Tea: 1 tsp crushed berries, simmered 10 min, once daily. Best taken consistently over several months
