Other studies indicate Chaste Tree Berry to effectively treat acne in both female and male teenagers.
In summary, Chaste Tree Berry is recommended for the treatment of PMS, abnormal menses, and fertility challenges especially if a progesterone deficiency is suspected. In 2 large studies conducted in Germany, with more than 1500 participants, 57% experienced significant improvement of PMS symptoms and 1/3 of the participants expressed 100% relief of symptoms. Clinical research shows that Chaste Tree Berry may work in as fast as ten days, but generally to see full effect one should take for a minimum of 3 full cycles. With PMS, positive results may be seen by the 2nd cycle but permanent improvement may take up to a year.
