Each month the endometrium becomes inflamed, and the luminal portion is shed during menstruation. Aberrations in menstrual physiology can lead to common gynecological conditions, such as heavy or prolonged bleeding. Menstrual dysfunction is defined in terms of bleeding patterns, for example, amenorrhea, menorrhagia or polymenorrhea; ovarian dysfunction for example, anovulation and luteal deficiency; painful menstruation and premenstrual syndrome. Certain characteristics of menstruation can be a reflection of an underlying pathologic process or may predispose a woman to the development of chronic disease. For example, metrorrhagia predisposes to anemia, and the irregular menstrual cycles associated with PCOS (see PCOS) can predispose a woman to infertility, diabetes and consequently, heart disease.What is it, in this age of life-saving antibiotics, hormonal therapy, surgeries and other seemingly miraculous medical therapies that causes so many individuals to seek therapies outside of conventional medicine? Conventional medicine may be at its best when treating acute crises, but for the treatment of chronic problems it may fall short of offering either cure or healing, leading patients to seek out systems of treatment that they perceive as addressing the causes of their problem, not just the symptoms. According to WHO, experience has shown that there are real benefits in the long term use of whole medicinal plants and their extracts, since the constituents in them work in conjunction with each other. Globally, it is estimated that 70% of all health care is provided by traditional, nonconventional medicine. Vitex agnus castus or chaste tree is one such herb which has a long history of use for common gynecological complaints.
