Join us for a transformative gathering in the heart of Cincinnati, Ohio, to celebrate the rich history, spirituality, and eclectic roots of herbalism.
The International Herb Symposium
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.
Announcing the 17th IHS
Theme: Herbal Traditions, Spirituality and the Eclectic Roots of Modern Day Herbalism
