International Herb Symposium

The International Herb Symposium (IHS) was founded more than 25 years ago by Rosemary Gladstar. Ever since, this bi-annual event has been 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.

This year’s event returns to an in-person format! Join us at Wheaton College in Norton, Massachusetts from June 9-11, 2023 for the in-person event. Sign-up for all three days or simply get a day pass. If you can’t make it to Wheaton College, we also offer an online-only Symposium, which launches later in June 2023. All in-person attendees also get free 12-month access to the online Symposium.
