One of my all-time reliable treatment choices, chaste tree berry is amazingly effective for regulating periods, preventing PMS, supporting fertility and managing peri-menopause. Many misunderstand this well-studied botanical and believe it’s a natural progesterone but it in fact normalizes normal ovarian function when taken daily. ‘Chaste’ tree also known as Monk’s pepper refers to its historic use to lower libido in men though it’s studied to increase libido in women!
