Ethnopharmacology stands at the intersection of traditional knowledge systems and modern biomedical research, providing a scientific framework for exploring the therapeutic potential of natural products. This interdisciplinary field investigates the cultural, biological, and pharmacological dimensions of medicinal plant use in indigenous societies. Despite significant progress in cataloging ethnobotanical data and isolating bioactive compounds, true interdisciplinary integration particularly with anthropological insights—remains limited. This paper examines the historical development, scientific mechanisms, phytochemistry, and modern applications of plant-based therapeutics. It further explores engineering approaches such as synthetic biology, metabolic engineering, and tissue culture to address the sustainability, standardization, and scalability of therapeutic compounds. Ethical and regulatory frameworks, including the Nagoya Protocol and WHO guidelines, are assessed to highlight the challenges and opportunities in protecting indigenous knowledge while fostering innovation. Case studies, such as Euphorbia peplus and Cordyceps, illustrate successful pathways from traditional use to clinical validation. The paper concludes by emphasizing the need for ethically responsible, culturally sensitive, and scientifically rigorous strategies for drug discovery and healthcare integration based on traditional pharmacopoeias. Keywords: Ethnopharmacology, Medicinal Plants, Phytochemistry, Synthetic Biology, Traditional Medicine, Plant-Based Therapeutics, Indigenous Knowledge, Drug Discovery.
