Ayurveda describes Rajaswala Paricharya as a set of dietary, behavioural, and lifestyle guidelines for women during menstruation. These recommendations aim to preserve reproductive health, maintain hormonal balance, and prevent menstrual irregularities. In modern society, however, this regimen is often overlooked. As a result, women continue to face problems such as dysmenorrhea, irregular cycles, and fertility-related concerns, which are further aggravated by stress, improper diet, and lack of rest. Aim: To evaluates the role of Rajaswala Paricharya in promoting menstrual and reproductive wellness, and its relevance in present lifestyles. Methods: References from Ayurvedic classics were reviewed and correlated with modern scientific studies on menstruation, hormonal changes, and reproductive physiology. Results: The analysis showed that Rajaswala Paricharya emphasizes rest, light and easily digestible food, abstinence from strenuous activity, and avoidance of certain practices like day sleep and excessive exertion. Neglect of these guidelines may lead to menstrual irregularities, reduced fertility, and pregnancy complications. Modern evidence supports many of these practices. For example, abstinence during menstruation lowers the risk of infection, and dietary recommendations such as consumption of barley and milk-based preparations are beneficial for uterine and hormonal health. Conclusion: Rajaswala Paricharya provides a preventive and holistic framework for menstrual care. By adapting its principles to contemporary lifestyles, it can support reproductive health and reduce menstrual disorders. Further clinical studies are needed for wider acceptance and application.
