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
This symposium is a unique opportunity to build community, honor the crossroads of plant medicine, and explore how herbal knowledge flows through history—like the mighty Ohio River—connecting us all.
Through five core tracks, you’ll dive deep into:
- Eclectic Medicine
- Alchemy & Plant Spirit
- Cultural Traditions
- Kitchen Apothecary & Medicine Making
- Reciprocity
Together, we will uplift the herbalist community, reflect on the challenges and triumphs of plant medicine in the past, address the issues we face today, and envision a sustainable future for herbalism.
For anyone interested, the Lloyd Library exhibit, Early American Medicine, will be open on Friday and Monday during the symposium, and a special library tour is available on Saturday from 2 to 3:30 PM.

- Build connections in the herbalist community.
