Our Mission

The International Herb Symposium is committed to creating a welcoming, engaging and inclusive gathering that represents and honors the diverse and varied traditions present in herbalism. We come together in honor of the plants and in the spirit of respect & reciprocity  to share and learn from one another. By coming together in this way, we strive to create  local & global communities dedicated to healing and caretaking the Earth and all beings.


Our History

Founded by Rosemary Gladstar in 1991, the IHS brings together plant lovers & herbalists from around the world, representing many traditions and aspects of herbalism: folkloric, scientific, community outreach & therapeutic applications, farming and gardening, ceremonial and plant spirit teachings and many others. Hosted biennially, the Symposium also places a special emphasis on medicinal plant conservation and is held as a benefit conference for United Plant Savers, a non-profit organization dedicated to the conservation of medicinal plants. We believe that by gathering in the spirit of the green, we can expand our communities, both locally and globally, creating a “mycorrhizal network” that helps to increase individual and planetary healing.

Held on the on the lands of the Sovereign Wampanoag Nation, at a small college campus located near Boston, Massachusetts, Wheaton College has all the amenities of a large campus, but its rural setting and beautiful old buildings add a special charm, grace and an interesting touch of academia to the symposium.  It’s also adjacent to 250 acres of woodland, which makes it ideal for herb walks and other outdoor activities.
