Learn A&P with our very own Wendy Warner, MD, ABIHM, IFMCP and Andrew Appello, DACM, MSN, L.Ac., APN, RH(AHG) available here! They are wonderful teachers and have a depth of knowledge on anatomy and physiology (as well as many other topics), especially as it pertains to clinical practice, that few others can offer. We believe you will find this class not only highly educational but deeply relevant to becoming a clinical herbalist.
From our students:
“This A&P course was extremely well-organized and proceeded on a lesson gradient with each body system connecting to the next. The herbal knowledge spread throughout the course helped to bridge the gap between how herbs and different parts of the body work together to achieve balance. It lays out a thorough foundation for any non-science degree individual looking to prepare for serious herbal studies.”-Kate McKinley
““I found this course to be exceptionally well-designed — an exciting and accessible entry-point into the study of anatomy and physiology. In particular, I appreciated the integrative approach which underlies this program, which is co-taught by a licensed acupuncturist, nurse practitioner and clinical herbalist and by a physician herbalist, each with years of experience in working between conventional clinical medicine, herbalism and other traditional healing modalities.” -Sarah Epstein

Learn MoreIn our program we strive to teach the skills necessary so that each student can accomplish that goal. We focus on differential diagnosis skills, materia medica and therapeutics which are essential to individualize treatment and help patients to not only resolve symptoms, but create constitutional change needed for physical, emotional and spiritual wellness.
Our ProgramsHaving been a student of David’s, it’s been fascinating to me how many times I pull on not just the herbal knowledge I learned from him but the deep well of wisdom which David transmits. I find myself referring to him when I’m talking about how we heal as a culture or how we honor the earth. The learning I carry with me from the Herbal Studies Program bubbles up in profound ways in so many parts of my life. I think that’s part of the magic of his formulations: his spirit is behind each one. Maia Toll
