Agnus castus has become well-known as a hormonal regulator for women. It is extremely helpful in a wide range of pre-menstrual problems such as spots, irritability, breast tenderness and bloating. It can help to regulate a woman's menstrual cycle, improve fertility, lengthen out a short cycle and even restore menstruation in a woman who has stopped her periods (although the underlying cause of this should always be investigated). For women entering the menopause, it can help to even out mood swings and improve hot flushes. Men can use agnus castus too for acne.Seek advice if suffering from polycystic ovarian disease.
