Herbalism isn’t something to memorize.


It's something to make part of your life.


Herbalism needs to be like second nature so you know what to do when it matters most...

When your child has a cough at 9pm
When you feel tired and wired, but can't get to sleep.

When your brain is foggy and you're thinking,
“I know there’s something for this…”

That’s what we prepare you for.

What This Is

These seasonal herbal classes started in a very simple place. We had these incredible materia medica cards —packed with over 50 years of herbal knowledge. And people loved them.

But also? They felt overwhelmed. There’s so much in them — images, energetics, tissue states, systems, terminology... And without in-depth context... it’s a lot.

So instead of adding more information… We did something different.

We sat down… with the cards… and started talking.

Inside each class, you’re not watching a polished lecture. You’re sitting in on a real conversation between herbalists. There are tangents. Stories. Moments where someone pauses and goes, “wait… what about this?”

And suddenly something clicks. Ideas build on each other in real time. Because you’re not just being told what a plant does. You’re seeing how people think about it. How they connect it to real life. How they remember it. And that’s the part most people never get access to.

Learn how to think like an herbalist.

About the Cards

At the center of all of this are the materia medica cards. Each one is like a compressed map of a plant. 

  • how it tastes
  • how it feels in the body
  • where it works
  • how it behaves in nature
  • what kind of person or pattern it supports


It’s decades of knowledge... distilled.

These classes bring the cards to life. You hear the stories behind them. You see how practitioners actually use them. You start to understand what those terms mean in real life. And over time…They are no longer just information. The plants and their uses become familiar.

What You’ll Gain

This isn’t about memorizing everything.

You will:
• Recall what you’ve learned—when it actually matters
• Recognize plants without second-guessing
• Start connecting patterns instead of collecting facts
• Think like a herbalist (without trying to memorize everything)


The Part People Love the Most

This is foundational teaching taught like it has been taught for generations: through the seasons, from stories, and in bite size pieces we can easily apply and remember.


This is for people who want herbalism to become second nature.

Who This is For

This is for you if:
  • You’re curious about herbalism… But tired of trying to memorize everything
  • You want to feel more connected to plants... Not just informed about them
  • You’re ready to learn in a way that feels natural, not forced

This is not for you if:
  • You want a quick, straight answer for every symptom
  • You prefer rigid structure and step-by-step certainty
  • You just want a list of “use this for that”

Stop collecting herbal information. Start using it.
This is where that shift begins.

Frequently asked questions

How does the seasonal format work?

Each season focuses on the herbs and conditions most relevant to that time of year, so the learning always matches what’s actually happening in the natural world. Follow along with the seasons or explore as you wish.

What are the materia medica cards?

The cards are a proprietary MWIH reference system — each one is a compressed map of a single plant covering how it tastes, how it feels in the body, where it works, how it behaves in nature, and what kind of person or pattern it supports. They represent over 50 years of accumulated herbal knowledge. The classes bring them to life through conversation rather than lecture. The Seasonal Herbalist cards are included in the course and the complete Year 1, 2 and 3 Materia Medica cards are included in the Library subscription and are downloadable.

Is this right for beginners?

The Seasonal Herbalist works best for people who have some curiosity about or exposure to herbs and want to deepen how they think about them. If you’re completely new to herbalism, the Starting Path may be a better first step. If you’ve been collecting herbal knowledge but want to actually use it, this is the right place.

How is this different from The Library?

The Library is a broad archive of 90+ clinical courses across many traditions and teachers. The Seasonal Herbalist is a focused, conversational series built entirely around the materia medica cards, two herbalists working through specific plants in depth, season by season. All Seasonal Herbalist recordings are included in the Library subscription. A standalone Seasonal Herbalist purchase is the right fit for someone who wants this specific content without the full Library.

Is this included in my Library subscription?

Yes. If you are a current Library subscriber, the Seasonal Herbalist course recordings are included in your subscription. Log in to access them.

Can I cancel anytime?

Yes. Cancel anytime from your account. If the course isn’t what you expected in the first 30 days, email us for a full refund — no forms, no hoops.
