Vitex (Chasteberry) is an excellent hormonal tonic for women. Extensive clinical studies as well as over two thousand years of use have proven the effectiveness of this remedy.¹ It works by stimulating and normalizing the pituitary gland, which regulates the balance of hormones, including estrogen and progesterone in the body.^1,2

In a normal menstrual cycle, estrogen is higher before ovulation and progesterone is higher after. An imbalance of these hormones, as well as other hormones including prolactin and serotonin, can lead to a range of symptoms associated with PMS. Prior to menstruation, many women find themselves irritable, depressed, and bloated. About 30-40% of women report experiencing problematic PMS symptoms, with 5-10% having very severe symptoms.¹ It is thought that the typical symptoms of PMS occur because of high prolactin levels and an insufficient production of progesterone in the two weeks prior to menstruation.^1,2 A number of studies have shown that Chasteberry has the ability to lower prolactin concentrations as well as to restore the estrogen-progesterone balance, which can offer significant relief from many symptoms of PMS.^1,2

In clinical studies, Chasteberry has been shown to be especially helpful for relieving breast pain and tenderness associated with PMS.^2,3 In another recent study of premenstrual women, over 90% of those who took Chasteberry reported that they experienced a significant reduction in the number and severity of their PMS symptoms, including physical complaints like pain and bloating as well as emotional complaints like mood swings and depression.¹ 

In addition to relieving PMS symptoms, Chasteberry has also been used to treat premenstrual dysphoric disorder (PMDD), to help restore cycle regularity, reduce menstrual-related acne and reduce the symptoms of menopause.^4-7  In one study, Chasteberry was used with women with menstrual cycle abnormalities. Their menstrual-related acne was either eliminated or improved during treatment. 

These positive results have been supported again and again in clinical studies, making  Chasteberry a highly effective choice for women looking for a natural solution for the symptoms of PMS.
