discover & prevent

the roots of disease

with Medical Astrology + Herbalism

Preventing disease before it takes root

As a holistic herbalist, you don’t just want the people you serve to be free from symptoms…

You want them to be vibrantly healthy.

Physically strong. Psychologically clear. Emotionally balanced. And spiritually evolving.

The paradigm of true holistic herbalism is based not just on treating disease, but preventing it by promoting health on all levels.

Unfortunately, most of modern herbalism is focused on allopathically treating symptoms.

Enhancing the Healing Power of Herbalism With the Precision of Medical Astrology

Most people don’t realize it, but astrology was once an integral part of western herbalism and the practice of medicine.

The medical branch of astrology gives you a detailed map of someone’s unique physiological landscape, predispositions towards disease, and how the health of the body is intricately woven into the mind, heart, and soul.

Medical astrology reveals what plants are best to treat the unique person, not their disease. It’s a map of disease prevention, potent herbal pharmacy, strategic formulation, and ultimately helps you to heal the whole person with the whole plant. 

The synergy of medical astrology and clinical herbalism is the ultimate map for preventative, rejuvenative, and transformational healing.

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.
