Our Story

The Elderberry School of Botanical Medicine was founded in 2006 by herbalists who wanted to provide a foundational lay herbal medicine education for adults in the Portland area. Since 2007 our nine month Herbalist Training Program brought people together in community with the plants and each other. Later, advanced courses were added to meet the need for more in-depth clinical study.


In 2019 we felt the need to make our programming more versatile and flexible for people with more focused interest. We decided to break up the foundational program into more accessible pieces and created new courses to meet the needs of students and alumni.


In 2023 we brought back the in-person Herbalist Training Program, while maintaining free standing online courses and one day hikes.

In 2024 we brought back our in-person advanced course, Clinical Herbalism, which accepts students who have completed The Herbalist Training Program or other programs that provide a year of foundational study.

Our Mission

We strongly believe that knowledge of local medicinal plants is essential for all people, and that herbal medicine is a core component of sustainable community health and vitality. We offer a bioregional approach that focuses on increasing knowledge and awareness of the medicinal plants of the Pacific Northwest, and we emphasize the validation of first hand experience and collaboration in teaching and learning. We offer an arena for aspiring community healers to learn to bring herbal medicines and people together, and by promoting the awareness of ethical wildcrafting, we ensure the protection of at-risk & endangered plants and the continued abundance that our local flora provides.

Our Instructors


Erico Schleicher MAcOM, LAc

Erico is a practicing clinical herbalist and acupuncturist. He has been discovering and working with plant medicines since 1994. His studies with Michael R.S. Moore at the Southwest School of Botanical Medicine put him on a path towards accessible and empowering herbalism based on traditional principles, with a bioregional focus. He has been seeing patients in Portland since 2003, combining his passion for local plants with the therapeutic principles of Chinese Medicine for a unique healing perspective.

He is deeply committed to sustainable directions for community health.


Erico finds that when we work seasonally with locally available plants that thrive in our bioregion, we learn to perceive the many voices that teach us how to integrate our own health into the life of the land around us.


In addition to co-founding the Elderberry School in 2007, Erico’s herbalism workshops have been featured at the Breitenbush Herbal Conference, The Portland Plant Medicine Gathering, The Dandelion Seed Conference, the Northwest Herbal Fair, Tryon Life Community Farm and the Montana Herb Gathering.


Erico has served on the Board of Trustees of Tryon Life Community Farm, The Olympia Free Herbal Clinic, and the Oregon Acupuncture Association. He is a faculty member at the Oregon College of Oriental Medicine. 


Kim Kelsey

Kim is a plant lover, nurse practitioner, and singer. She grew up exploring the woods and beaches of Washington State on the Puget Sound. Throughout her childhood Kim was intrigued by plants and their uses as medicine. Following her interests, Kim studied botany and ecology at The Evergreen State College. Later, she chose nursing as her healing discipline, drawn by its person-centered and holistic approach. Kim sees patients at Hand On Medicine, an integrated primary care practice in North Portland.


Kim is a founder of the Elderberry School of Botanical Medicine. She has created a unique anatomy and physiology course for herbalists that entwines her knowledge of plant medicine with her understanding of the human body.


Kim’s work with the school also includes teaching songs and fostering a culture of music in the program. Music is a traditional part of healing work, and Kim has witnessed how singing together can open new ways of understanding ourselves and strengthen community. Kim learned many of her songs from singers at the Singing Alive gathering in Cascadia.


Kim manages the website and social media content for the school. She loves to find ways to share the experience of hiking, gardening, and medicine making through photography.



Ashtree began her herbal journey in 2012, initially inspired by fire cider, kitchen remedies and healthy whole food cooking. Since then, she has tended plants and gardens, starting with a few pots on the porch, working for other local vegetable farms and nurseries & eventually expanding to a backyard field of food and herbs! She has completed Rosemary Gladstar's Science & Art of Herbalism Program, the Dandelion Herbal Center's 10 Month Herbal Studies Program & the Herbalist Training Program at The Elderberry School of Botanical Medicine. Ash took the leap to start Wiggle Way Farm in 2021, a small-scale medicinal/culinary herb farm, nursery & apothecary. Wiggle Way Farm sells plants, seasonal fresh herbs, tinctures, teas, spices, oils & salves at local farmers markets. Ash loves starting seeds & saving seeds, and is currently enamored with learning how to propagate more PNW native plants from seed. Here we grow, for the plants!
