Chaste Tree is you herb of choice here. Its botanical name is ‘vitex agnus castus’ and it works! I prescribe it to almost everyone of my female clients, and I myself have been taking it on and off for over 20 years now. It works! Did I mention that? I recommend taking 2.5 ml of the liquid (practitioner-only if you can) in the morning. Find it in health food stores or from your health practitioner
