How Class Works
Regular Classes

Our regular class times are Tuesdays and Thursdays from 10:00 am until 1:00 pm. Our classes will be held online using Zoom. Heather Luna will be your instructor for the Footprints program. 

Self-Study/Audio files

Listening to Paul's recorded classes is an essential aspect of our herbal learning environment. These lectures are full of valuable information and experience that drives the entire program. You will listen to the assignment (audio file) and write a reflection paper to discuss in class. 

Medicine Making/Herbal Formulations

Feeling, smelling, and tasting herbs are important aspects of herbalist training. Normally we would make herbal medicines together in a classroom setting. Since we are now holding classes online, all students will receive a Medicine Making Care Package at the beginning of each Course (4 packages total), that will contain all the herbs and medicine making materials needed to complete the lessons for that Course at home. In each chapter of the material, students will read the lessons and make the herbal preparations on their own time, then do the tasting and journaling exercise at home, and finally we will have a discussion and comparison together as a class online.

​​​​Course Description

All classes are held in real time via Zoom

This is an entry level, in-depth program that provides essential training in the foundations of Western Herbalism with a total of 348 hours of study. The core curriculum was created by Paul Bergner for the North American Institute of Medical Herbalism. All class hours are taught by Heather Luna. Completion of the Footprints in Medical Herbalism program grants students a certificate from ACORN for 192 hours of class time and an additional certificate from NAIMH for 156 self-study hours. 

 “This is an entry level course for the study of herbal medicine, and presents the context of the vitalist approach to healing, nutrition and lifestyle, and also a basic introduction to formulation, with case-based study ... you will learn how to study an herb, which will establish a foundation for effective future learning. This is a project-oriented course, you will taste the herbs, journal their effects, make your own tinctures, devise formulas, and study actual clinical cases. Do not mistake this to be a simplistic introductory course, it contains within it the inspiration, hands-on experience, tools, terms and concepts, and methods of application, and case based learning that many contemporary herbalists missed out on in their own education.” -NAIMH
