Learn MoreLearn 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 MoreMy experience with David Winston’s online clinical herbalism course was fantastic! David is thorough, professional and honest about his knowledge and experience with the herbal world. The Materia Medica was extensive and very comprehensive. His ability to compile massive amounts of clinical and historic information on the uses, contraindications, dosages along with climate and anecdotes on the 100’s of herbs in the materia medica is a continued wonder to me. I honor his dedication to the preservation and expansion of Herbalism and over the 3 years of study with him have grown to trust his opinion which was always clearly stated if it was either his opinion and/or based on some experience or clinical trials. His clarity and dedication is to be commended. I highly recommend this course.
