Women’s Reproduction

Vitex agnus-castus is known for its ability to improve conditions affecting a woman’s reproductive system.

Ease Symptoms of PMS

It reduces symptoms which include constipation, irritability, depressed mood, migraines, and breast pain and tenderness. Researchers believe that it works by decreasing levels of the hormone prolactin. This helps rebalance other hormones including estrogen and progesterone, therefore, reducing PMS symptoms. It also appears to help reduce cyclic mastalgia which is a kind of breast pain linked to menstruation. Better study designs are needed for strong conclusions.

May Reduce Menopause Symptoms

The hormone-balancing effects of it may also help relieve symptoms associated with menopause which includes better mood and sleep. Keep in mind that in many studies showing benefits, women were provided with supplements mixed with it with other herbs. Therefore, it is difficult to isolate the effects of it alone.

May Enhance Fertility

It may improve female fertility due to its possible effect on prolactin levels. This may be especially true in women with luteal phase defect or a shortened second half of the menstrual cycle. This disorder is linked to abnormally high prolactin levels which makes it difficult for women to become pregnant. It also prevents miscarriages.
