17th International Herb Symposium in Cincinnati and Online
17th International Herb Symposium in Cincinnati and Online

September 12 @ 9:00 am – September 14 @ 5:00 pm
I am honored to be presenting two classes – one in-person and live-streamed and one online – at this year’s 17th International Herb Symposium in Cincinnati. Recordings of those classes and all the rest of the presentations will be available online for one year.
The IHS is the premier herbal conference of 2025, featuring renowned presenters like Rosemary Gladstar, Christopher Hobbs, David Winston, Matthew Wood, Emily Watson of Artemisia Academy, and many other noted herbalists and authors. Founded by Rosemary Gladstar in 1991, the IHS brings together plant lovers and herbalists from around the world, representing many traditions and aspects of herbalism: folkloric, scientific, community outreach and 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.
On Saturday, September 13, at 2:00 p.m. EDT in Cincinnati on the Main Stage in the historic Memorial Hall I will present a slideshow talk on “The Twisted History of Herbal Medicine in America.” Follow this link, scroll down to my Saturday class, and click to learn more about it. That presentation will also be live-streamed.
I will present a second slideshow talk, online-only, about the making of my book, Medicinal Herbs of California, entitled “More Than a Field Guide: Writing with Ecological and Cultural Respect.” That one is not posted yet. I will update this page when it is.
