Menstrual disorders have long been a subject of significant concern for gynaecologists and physicians, both in ancient and modern times, due to their profound impact on women’s health. Among these, Polymenorrhea represents one of the most prevalent complaints among menstruating women, affecting approximately 5–15% of the adult female population. It adversely influences physical, emotional, and social well-being, thereby diminishing the overall quality of life. Polymenorrhea refers to abnormally frequent or shortened menstrual cycles, which may occur as a physiological variation or as a manifestation of underlying pathological conditions. Under normal circumstances, menstruation follows a cyclical pattern lasting up to seven days; however, deviations in frequency or duration may indicate menstrual dysfunction. In the Unani system of medicine, this condition is referred to as Kathrat-i-Ḥayḍ, denoting excessive menstrual bleeding. When the bleeding persists beyond the normal menstrual period or occurs irregularly on non-menstrual days, it is termed Istiḥaza. The Unani scholars have elaborated extensively on its causes, underlying mechanisms, and management strategies. This paper aims to elucidate the etiological factors and pathogenesis of Kathrat-i-Ḥayḍ as described in classical Unani literature, thereby contributing to a deeper understanding of its conceptual and clinical significance.
