The Chestnut School of Herbal Medicine was founded in Cherokee Nation territory, in what is currently known as Asheville, North Carolina, nestled in the botanically rich Southern Appalachian Mountains.

We offer several online opportunities to learn, including the Herbal Medicine Making Course, the Foraging Course: Edible and Medicinal Wild Herbs, and the Herbal Immersion Program. Take a peek at our Course Comparison Chart to see which learning option is the best for you!

Bioregional Herbalism for Personal and Planetary Health

Just as locally grown food is key to long-term sustainability, so is locally grown medicine. That’s why our programs focus on growing your own herbs and all the ways you can enrich your life with edible and medicinal weeds. Preparing herbal medicine is a deeply satisfying and sovereign practice, and an essential aspect of all traditional cultures across the globe.

Our connection to plants as medicine nourishes this ancient spirit and wakes us up to the profound natural cycles of life. We’re honored to share that connection with you, and we hope it brings you as much joy as it brings us!

All are Welcome at the Chestnut School

We will always welcome people from all races, nationalities, socio-economic backgrounds, ages, abilities, sexual orientations, and gender identities, as well as cultural, political, religious, and other affiliations. ALL are welcomed with open arms at The Chestnut School.

We foster an inclusive and safe educational space through open communication, humility (a willingness to listen & learn from our mistakes), and mutual respect for different beliefs and backgrounds.

Sharing the same beliefs as your fellow students is not a requirement to study with the Chestnut School, but treating everyone with dignity and respect is.

Juliet Blankespoor (she/her)

Founder • Visionary • Creative Director


I founded the Chestnut School of Herbal Medicine in 2007 and serve as the school’s primary instructor and Creative Director. I’ve been a professional plant-human matchmaker for close to three decades. I caught the plant bug when I was nineteen and went on to earn a degree in Botany. I’ve owned just about every type of herbal business you can imagine: an herbal nursery, a medicinal products business, a clinical practice, and now, an herbal school. I’m pleased to say that I am the 2019 recipient of the United Plant Savers’ Medicinal Plant Conservation Award.
These days, I channel my botanical obsession with my writing and photography in my online programs and my personal blog, Castanea. I’m writing my first book: The Healing Garden: Cultivating & Handcrafting Herbal Remedies. My houseplants and I share a home with my family and herb books in Asheville, North Carolina.

Our Mountain Home

Juliet moved to the southern Appalachians after studying with several herbalists –7Song, Michael Moore, and James Snow—and sowing her wild oats (herbal style—which involved camping in pristinely beautiful spots to gather herbs, seaweed and mushrooms). After settling in the mountains and planting her herb garden, she opened the Chestnut School. Around the same time, Juliet founded the Chestnut Herbal Nursery, which she owned and operated and planted and propagated for seven years.

After many years of teaching intensive, all-outdoor herbal programs, Juliet has decided she is a raging introvert and her teachings are best suited to the virtual sphere. Juliet is delighted to continue to teach and connect with herb lovers through the ethers. See her full bio here.


We’re dedicated to promoting all kinds of diversity in the field of herbal medicine. To that end, we’ve partnered with several non-profit organizations that work with underserved populations in sustainable agriculture. We’re donating scholarships to both workers and volunteers in the respective organizations, along with the folks they serve.

Our scholarship program is on hold until further notice. To receive an email when the application period reopens, please sign up for our newsletter list. To find out more, please see our scholarships page.

We support public botanical gardens and plant conservation through annual donations or memberships at the North Carolina Arboretum, Asheville Botanical Gardens, United Plant Savers and the American Chestnut Foundation. Additionally, the Chestnut School is a member of the American Botanical Council, the American Herbalist Guild, and the Herb Society of America.

Here is a testimonial from one of our students – click here for more:

“The Immersion offers so much more than you think you’re going to get. Not only will you learn about these amazing plants and how to grow them, you will also learn about the human body and how herbs affect each system–and not in a general way. These courses teach you how to understand plants in various preparations and how each type of preparation will extract different properties of the plants. You will no longer be doing a web search on remedies for various ailments, because in the Herbal Immersion Program, you are given such tailored and focused instruction that not only includes information, but wisdom on how to apply all of this knowledge. They teach you both the science and the art of herbalism. A student can go as deep as they want with all these tools provided. I cannot express enough gratitude for this course.”
~Marianela Leekley, Online Herbal Immersion student

Christine studied at the Chestnut School in 2013 and is thrilled to be back as a part of the Chestnut team to support our students in their herbal learning. Christine currently resides in the magical driftless region of southwestern Wisconsin, the ancestral land of the Ho Chunk Nation, with her partner, daughter, and wild rescue pup.

Jessica Janoff (she/her)

Student Services Specialist

Jessica is a North Carolina native from near the coast in Greenville, NC. Most people are hyperbolic when they say they’ve ‘always’ been interested in their field of choice. At 8 she pulled a pathophysiology book off a Dean’s office shelf, enamored with it, thrilled to keep it, and interest ignited in healing and science. Now Jessica lives in Midcoast, Maine, within the Nanrantsouak territory within the Wabanaki Confederacy, with her husband and three boys in an old farmhouse she fills with plants, tinctures, and one day a poison garden.

Five years spent as an herbalist with vast knowledge in product development led Jessica to start Nourished Earth Apothecary to provide one on one services to clinical clients seeking herbal remedies for chronic ailments, physical conditions, and allergies. Ten years of providing support to students in college and laboratory work while obtaining her Biochemistry degree from North Carolina State University shaped her dedication to academic achievement and investment across many ages and education levels. Jessica serves her clients, and community with a blend of Eastern and Western herbalism perfectly through equanimity, accessibility, and advocacy.
