Abstract
Menstruation, as one of the most important physiological cycles in women, was regarded in ancient civilizations not only as a biological process but also from spiritual, social, and medical perspectives. In ancient Mesopotamia, menstrual blood symbolized life and fertility and was sometimes associated with supernatural forces, with treatments for related disorders, including herbal remedies and religious rituals. In ancient India, Ayurvedic texts considered menstruation (Artava) sacred and an indicator of women’s health, describing its characteristics in terms of the balance of the three doshas (Vata, Pitta, Kapha), and prescribing treatments, such as dietary regulation, medicinal plants, and oil-based or thermal therapies. Traditional Chinese Medicine viewed menstruation as a reflection of energy balance and Qi flow, with its disturbances attributed to Yin-Yang imbalance; treatments included herbal medicine, acupuncture, and lifestyle modifications. In ancient Iran, Pahlavi, and Zoroastrian texts, such as the Bundahin, divided the menstrual cycle into three stages Pē-ābest, Ābest, and Datān addressing fertility periods, the influence of gamete sequence on fetal sex, and menstrual restrictions. These studies indicate that ancient civilizations’ perspectives on menstruation combined physiological understanding, traditional therapeutic practices, and cultural-spiritual dimensions, and that ancient Iranian knowledge of reproductive physiology demonstrated notable accuracy and systematic insight.
