The International Herb Symposium

The 16th International Herb Symposium was a great success! Thank you to all our attendees, sponsors, vendors, staff, volunteers and teachers who made it possible!

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.
