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 International Herb Symposium
Celebrating the roots of American herbalism with the theme “The History of the Eclectics.” Mark your calendars for this hybrid event, which will offer in-person and virtual attendance options:
September 12-15, 2025 ~ Cincinnati, Ohio
(The new venue will be announced at a later date.)
We’re moving the event to Cincinnati to get you within driving distance of the United Plant Savers Botanical Sanctuary. Attendance on Monday, Sept. 15 will be an optional field trip to the Sanctuary!
We’ll be reimagining some aspects of the Symposium while maintaining long-time favorites (Herbalists Ball, anyone?). We’re also seeking ways to lower the price, making it more economical than ever before. To help us plan the kind of event you’d want to attend, please take a minute to fill out our quick survey. We’re so grateful for your input!
