Welcome to The Science & Art of Herbalism

Herbal Greetings. I warmly invite you to join me on a magical and marvelous journey into the very heart of herbalism Realizing not everyone could leave home to study with an herbal teacher, I began offering my herbal home study course over 30 years ago and then, an online version a few years ago.  The Science & Art of Herbalism has continued to inspire, inform and teach hundreds of students over the past three decades ~ and I continue to be inspired by the dedication and commitment of my students.  In this 10-lesson course you will learn all of the basics of herbalism from hands on preparation and medicine making to plant identification and hundreds of herbal recipes for health and healing.  Herbalism is for everyone interested in self-health, well being and healing and is easy for everyone to learn.  I look forward to sharing your journey into the Green Nations with you.  And in this spirit, welcome you to be a part of my online portion of the course.  We have been working endlessly to create a new version and are hopeful you will join us on our new platform.

With love,
Rosemary Gladstar

Welcome to The Science & Art of Herbalism

The Science and Art of Herbalism Home Study Course is a ten lesson course taken at your own pace, with homework review and guidance provided by carefully selected herbalists and Rosemary herself.  Though it thoroughly instills in the student the practical skills necessary to practice herbal home health care, it doesn’t ignore the rich spirit and essence of herbalism. The heart of this course is the development of a deep personal relationship with the plant world. Many of our students have written telling us that this course has been transformational and one of the most self- empowering studies they have undertaken.

Many of our students have written telling us that this course has been transformational and one of the most self- empowering studies they have undertaken.

At the end of the course you will receive a beautiful certificate of completion that you can proudly display in your home, store or office! Thousands of people have taken this herbal journey with Rosemary over the past 25+ years, bringing herbal healing into their homes and communities.

As herbalism continues to spread its roots and grow in communities across the globe, Rosemary recognized that an online version of the Science and Art of Herbalism would benefit many of her students.  Computer savvy herbalists, Jason Colvard and Helen Ward spent countless hours creating the online format for the Science and Art of Herbalism, with the same core content as the classic printed version. Online students will benefit from all of the magic of the digital world – from videos, online peer communities, an herb of the month feature and a faster turnaround time on homework review.

There are still many of us who, like Rosemary, would prefer to curl up with a cup of tea by a sunny window, and read the course material in book form. Or perhaps there is no easy online access where you live. The printed course is as wonderful as ever, and provides three full years to complete with an option to extend if you wish. You will have the option to send your homework’s in for review via the postal mail or e-mail.

For those who want the best of both worlds, there is an option to purchase both the online and printed versions. If you would like to sample the course, you are welcome to order the printed Lesson 1. (At this time we are not able to offer a digital/online preview.) If you are enchanted by Lesson 1 you can continue with your studies by selecting the Lesson 2- 10 option, either printed or with the online course, or decide to enter the online course.

Rosemary weaves the magic of nature, a reverence for life and a commitment to share the wisdom of herbs with others throughout her teachings. We can’t wait to have you join her on this journey into the green world!
