A transformative gathering in the heart of Cincinnati, Ohio, to celebrate the rich history, spirituality, and eclectic roots of herbalism.
Join us at the International Herb Symposium.
This Symposium focuses on the Eclectic Roots of Modern Herbalism. It’s a unique opportunity to explore how herbal knowledge has flowed through history—like the mighty Ohio River—connecting us all.
Founded more than 25 years ago by Rosemary Gladstar, this biennial event continues to be a place for herbalists from across the globe to exchange information about the healing power of plants. The Symposium holds a special place among herbal conferences, bringing together people from diverse backgrounds and ways of working with medicinals.
