Medical Astrology + Clinical Herbalism...

a truly holistic system of clinical herbalism

Astrology is sorely misunderstood these days:  fortune telling, who you should marry, what job you should get, mere pseudoscience, a laughable paragraph in the Sunday paper…

Few realize it was once an integral part in the practice of traditional medicine, including systems of herbalism both East and West. 

Medical astrology is simply another approach to practicing holistic herbalism, lending insights into assessing clients, classifying remedies, human and plant energetics, and core therapeutic principles. 

Similar to Ayurveda, Chinese Medicine, and other systems of herbalism, it recognizes the whole person, the whole plant, and their relationship to the wholeness of life.

Ultimately, it’s another tool in your toolbox to help you better heal the people you serve.

The Mystery Tradition of the West

The Mystery Tradition of the West

The root of these teachings stem from the mystery traditions of the West. Throughout the program, you’ll learn how astrology ties into Alchemy, Spagyrics, and archetypal patterns such as the Tarot. These esoteric traditions can lend insight into using astrology with your wildcrafting, harvesting, and medicine making preparations.
The Curriculum

Each lesson for each sign is broken into three main sections: Natural Correspondences, Human Correspondences, and Botanical Correspondences. This gives you a well rounded understanding of each archetype and their unique spectrum of relationships, virtues, and patterns. Below is a more detailed outline of what you’ll learn under each sign of the zodiac:

“I’ve been studying astrology for almost 20 years now and I have never understood it so completely as I am now, going through it with Sajah in this program.”

Sajah Popham

Author of Evolutionary Herbalism: Science, Medicine & Spirituality from the Heart of Nature

Hey there! I'm Sajah, core instructor and founder here at the School of Evolutionary Herbalism. You're probably wondering who I am and what my qualifications are.

I received a BS in Herbal Sciences from Bastyr University 2008, which formed my foundation in herbalism: rooted in science but also central to my Earth-centered spirituality. From there I received clinical training through studying and shadowing some of the best herbalists.

For the past decade of teaching thousands of folks from around the world through our school, my goal has been to have a truly holistic approach to people and plants, one that honors the physical, energetic and spiritual aspects of life. I strive to support people in transforming their lives, to not just be symptom free— but physically vital, mentally inspired, emotionally uplifted, and growing into their life purpose. The plants are at the root of this transformational healing, for that's what they have provided to me.

I hope to be able to share a little bit of the medicine I have gathered along my plant path with you.
