This book investigates the physiological reality of Premenstrual Syndrome (PMS) and argues against the historical medical dismissal of these symptoms as psychosomatic. Dr. Katharina Dalton, a pioneer in the field, utilizes her extensive clinical experience treating over 50,000 patients to establish a framework for understanding, diagnosing, and treating the condition. By presenting clinical data and patient histories, the author shifts the discourse from psychological speculation to biological management.

This work is regarded as a foundational text in the history of women's health, credited with legitimizing PMS within the medical community. The framing suggests a clinical yet accessible approach intended for both patients seeking relief and medical professionals requiring a comprehensive overview of the condition.
