An Intensive Intermediate Course designed for those who wish to improve their skills as an herbalist, to learn to craft elegant herbal formulas for self, family and community with confidence and care.  Applicants must have a basic formal education in Western herbalism and the drive, dedication and desire to become a proficient and confident herbalist. 

Drawing from the expertise and experience of a well-rounded faculty, with many years of clinical and teaching experience, our intermediate-level course goes beyond “the basics” to put your knowledge of plant medicine to practical use, expanding on what you've learned in a beginning-level program.

Class begins on Sept. 2^nd  and meets every Tuesday evening in addition to several weekend intensives. Students have the option of joining us live in the classroom on Tuesday evenings or joining virtually. Weekend intensives are in-person, hands-on classes.  All classes are held in Petaluma.
