"what's it good for"


and understand your herbs with depth and precision

Learning herbs... the struggle is real

Have you ever been curious about a medicinal plant and gone to your herb books to learn more…

And end up disappointed by just a few sentences on what it’s “good for” or long lists of constituents and actions?

Do you ever feel like you’ve read about an herb over and over again, but still don’t feel like you understand it completely?

Unfortunately, a lot of books just graze the surface of the plants and don’t use the herbal monograph as a teaching tool to understand how to learn an herb.

You wouldn’t want to just know your friends at surface level, so why learn herbs superficially?

What's the key to becoming a better herbalist?

Is it wildcrafting more? Making more tinctures? Getting better at plant ID?

While those are important, the true path to herbal mastery is consistent study and experience of materia medica. 

But that doesn’t mean just reading about herbs every now and then. 

There’s a strategic way to approach learning herbs so you come to understand them with depth, not just superficially knowing about them. 

Truth is, effective herbalists know their remedies far beyond what symptoms they’re “good for.”

They know the essential healing pattern within each plant and how every medicinal virtue weaves together into a complete whole.

So how exactly do you approach studying plants holistically to get beyond superficial herbalism and come to understand their core medicinal essence? 

How do you develop herbal competence so you can heal the people you serve with the herbs you know and trust with confidence?

Core herbal patterns & properties

Core Herbal Patterns & Properties

Learn herbs by heart through seeing the relationship between the tastes, actions, organ/system affinities, energetics and special potency/specific indications of each plant, understanding the structural and functional patterns behind how a plant affects the human body.
Start Here
Essential clinical indications

Essential Clinical Indications

Learn how to apply the core patterns and properties of herbs to specific symptomatic and disease patterns in people. Rather than lists of symptoms, you’ll learn how the herbs address the underlying physiological processes behind them so you get more specific in your remedy selection. Learn to apply the energetics and constitutional picture of the plant, as well as any specific indications for when to use that remedy.
Herbal safety

Herbal Safety & Contraindications

Keep your clients and those you love safe by knowing any contraindications, side effects, herb-drug interactions, and pharmacological data about each plant so you know how that plant functions on a biochemical level.
effective extraction & preparation

Effective Extraction & Preparation

Each plant has a unique biochemical profile that yields to various solvents and methods of preparation. You’ll learn the best preparations for each plant, as well as our personal experience with spagyric and alchemical preparations.
dosage & administration

Dosage & Administration

To effectively use herbs clinically, you have to know the various methods of administration, as well as what the effective dosage and frequency is to have the desired result.
Flexible Formulation Strategies

Flexible Formulation Strategies

To have a well rounded understanding of a plant, knowing how to formulate with it is essential. Each lesson will provide simple pairs, triplets, and complex formulas based around that plant to give you a starting point for formulating it to exemplify its various properties.
Traditional & Modern Perspectives

Traditional & Modern Perspectives

Each monograph includes an integrative approach to understanding the plants based on traditional models by synthesizing the wisdom of Ayurveda, alchemy, medical astrology, traditional Western herbalism, and modern science for a well rounded physical, energetic, and spiritual understanding of herbal medicines.
Esoteric & Spiritual Properties

Esoteric & Spiritual Properties

To be truly holistic, you must learn not only the physiological actions of the herbs, but their subtle esoteric and spiritual properties as well. This is done through the lens of alchemy, learning the planetary and elemental correspondences of the plants and their relationship to the energetic architecture of nature.
monograph as teaching tool

The Monograph as Teaching Tool

To us, an herbal monograph isn't just a way to learn about a plant, it's an organizational framework to learn the principles of herbal medicine as well. As you learn your remedies, you're also studying A&P, constitutional systems, energetics, pathophysiology, chemistry, tastes, actions and more. This makes our monographs perfect for the beginner while leveling up the skills of the advanced practitioner.

What's in a monograph?

We believe we’ve created the most comprehensive herbal monographs out there. These aren’t just lists or short paragraph descriptions.

These are strategically designed to teach you the core principles of herbal medicine, to understand not just how to use a remedy, but the why and how behind it.

We treat the herbal monograph as a sophisticated teaching tool to learn holistic herbal medicine.

Most of the PDF monographs are well over 20 pages long, and the accompanying video lessons range between 2-3 hours. All on a single plant!

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.
