This class blends the scientific with earth-based traditional wisdom, and balances indoor classroom time with exciting outdoor daylong herbal adventures. No prior training, experience or pre-requisites are required.

We'll discuss common illnesses and how to approach them holistically using herbs, nutrition and healthy lifestyle choices. This course consists of classroom lectures and experiential learning. Over the course of nine-months, you will learn a variety of medicine making techniques including the proper preparation of medicinal herbal teas, glycerites, tinctures, syrups, oxymels, electuaries, acetums, liniments, oils, salves and more.

Schedule & Fees:
Class meets every Wednesday evening beginning September 6th from 6:00 to 8:30pm (live in our classroom or over Zoom).  In addition, students meet in-person at our field campus on a beautiful 50-acre ranch in East Petaluma two Sundays a month for hands-on instruction.  The course is $2,500 with monthly payment plans available.  A non-refundable deposit of $500 holds your space.  Register early - we sell out every year!  We also offer two optional (but highly recommended) camping trips in April and June at an additional $250 each.

This is a rigorous foundational program designed to teach you the basics of Western herbalism and prepare students for our Intermediate and Advanced Clinical Herbal courses. In order to successfully complete this course, students are required to put in additional time outside of the classroom to complete all homework assignments and, most importantly, get to know the medicinal plants we discuss for health and wellbeing, including those growing in the wildlands and neighborhoods where you live. In order to embrace herbalism fully, you must dedicate yourselves to the plants - and what a meaningful path you’ll begin to walk.
