Aralia School of Herbal Medicine
The Aralia School of Herbal Medicine exists to share experience based, practical knowledge with both aspiring herbalists and established practitioners. I want to give people tools to realize agency over their health, and deepen understanding of the body and how herbs work within it. My offerings aim to be detailed and physiology based. Through knowledge of herbs and the body, we can achieve better health for ourselves and our communities.

Caty Crabb | Clinical Herbalist
My work is rooted in the belief that herbal medicine should be as accessible as it is effective. With over 20 years of clinical experience, I’ve seen the impact herbs can have in addressing health concerns and shifting patterns in the body when applied skillfully.
I was fortunate to train under Michael Moore at the Southwest School of Botanical Medicine and Adam Seller at the Pacific School of Herbal Medicine. My teaching merges their deep lineage with my own clinical experience. My goal is to help you move past confusion and misinformation by sharing what actually works—and why—so you can practice with confidence.
Whether you are an aspiring herbalist or a seasoned practitioner, I am here to help you strengthen your craft with tools grounded in physiology, tradition, and two decades of professional insight.
In my opinion, there is no substitute for learning from someone like Caty who can tell me how she’s actually used a particular herb over many years, and what the results have been. Her experience and willingness to share is invaluable and a treasure to the community.

The detailed focus on each organ system and the supportive learning structure really made it useful. This was perfect timing for me before taking further classes.
