Jon Oleson

Western Herbalist, Flower Essence Clinician, Plant Communication Guide​​

I started down my current path following a spiritual healing crisis. After graduating college (BA) in Middle East Studies and Arabic, I found lucrative employment with the National Security Agency (NSA) as a translator. The final two years of this post-collegiate endeavor was spent in and out of Iraq, where I worked as a private contract interpreter for US liaisons on military bases. One day I reached a breaking point. My heart hurt. I met depression for the first time in my life. I was mentally, physically, and spiritually exhausted. Time was ripe for change.

In my younger years I spent much of my free time in the Great Outdoors. I am grateful to my father for the appreciation he taught for just being immersed in wild places. My most vivid memories are the scent of the desert Sagebrush after a rain, sweet pine resin floating on the crisp fall breeze, and putrid marsh mud bubbling beneath my boots. That connection early on was transformative in my curiosities and passions later in life. Remembering the clarity and calm that I always felt amongst the plants, and my persistent curiosity for getting to know my local plant community, I left my home in Salt Lake City to study Clinical Herbalism at the North American Institute for Medical Herbalism (Colorado School of Clinical Herbalism) in Boulder, CO.

Two years later, my life was completely transformed. My diet transitioned from vegan to paleo-ish. I experienced profound physical and emotional healing. Life was (and continues to be) exciting, inspiring, and purposeful. Most of all, I gained a broader linguistic perspective and expanded my community to include all beings. Having studied language I realized that the way plants heal is through interpersonal communication. In our culture this often happens on a subconscious level since we’re not given tools to interact. Acting as an interpreter I began working to reconnect my human community with the plant allies by focusing on the heart as a primary mode of consciousness. This role fills me with deep love and passion, and I’ve come to view it as a spiritual purpose in life.

Jahwei Chen-Graf
Clinical Herbalist, Naturopath, Holistic Nutritionist

Jahwei’s immersion in the world of medicinal herbs began over 20 years ago in the Swiss Alps where she spent her summers wild-crafting with her mother-in-law, Rosanna, a folk herbalist. Glorious hours were passed in the mountains harvesting plants and later turning them into teas, syrups, ointments and tinctures. Jahwei tested out these traditional herbal remedies on her family and friends and when they reported improvement she was pleasantly surprised at the power of these simple plant medicines. What’s more, she discovered that just being outside- in nature, connecting with the plants is powerful medicine in itself. 

With her interest in natural medicine ignited, she decided to formalize her education by completing a Bachelor of Naturopathy Degree from Southern Cross University (Australia) in 2007. Her main herbal teacher during those four years was Dr. Sue Evans who encouraged her not to be a “brown bottle herbalist’ but to go out and form relationships with the actual plants by tasting, growing, wild-crafting and directly experiencing. After graduation, she completed her naturopathic internship at Ruth Trickey’s Melbourne Holistic Health Group and practiced as a naturopath in Byron Bay specializing in Women and Children’s Health.

Since she moved to Nevada City she has continued to learn and be inspired by local herbalists, mentors and the plants themselves. Between 2011-2016 she completed herbal apprenticeships with Kathi Keville, Candis Cantin and Dr. Christopher Hobbs. Since 2012 she has worked behind the counter at HAALo offering her services as a community herbalist, homeopath and teacher.  

Jahwei maintains a private practice as a clinical herbalist, naturopath and holistic nutritionist and enjoys helping people reach optimal health by stimulating their own vital force to heal and minimizing any obstacles to cure. She loves teaching and is grateful for the opportunity to learn from her clients and students alike. Her approach is heart-centered, practical and seeks to incorporate wisdom from both traditional and scientific systems of medicine.
As well as being a wife and mother of three beautiful children, Jahwei is an avid wild-crafter, herbal educator, organic gardener, medicine maker, food lover, world traveler and creator of Remedy Garden Botanicals.
