Long before the term “nutraceutical” was coined, traditional cultures around the world were harnessing the healing power of food. At the Traditional Medicine and Ethnomedicine World Conference TMEWC 2026, this session uncovers the wisdom behind traditional diets and their transformation into today’s evidence-based nutraceuticals. From fermented botanicals to mineral-rich roots and age-old tonics, we’ll explore how these time-tested sources are being scientifically validated and developed into powerful health-promoting agents. This session welcomes experts from traditional medicine, ethnomedicine, and natural product science to discuss how the divide between food and medicine is becoming increasingly blurred and how historical knowledge is driving a new era of preventive health.
