Forget “what’s it good for?”
Start practicing herbalism with depth, nuance, and razor-sharp precision.
Learning herbs? Yeah… it’s harder than it looks.
You crack open a book, eager to dive into that one herb you’ve been hearing about.
Instead, you’re hit with this:
– A vague list of what it’s “good for.”
– A wall of chemical constituents.
– Actions like “alterative” and “astringent” with no real context.
You close the book, feeling like you should understand it by now — but somehow… you don’t.
Here’s the truth: most herb write-ups barely scratch the surface. They tell you what a plant does, but not how it does it — or why it matters.
Imagine getting to know a friend by memorizing their résumé. That’s what superficial herbalism feels like.
You need more than bullet points. You need a way to actually think with herbs.
So… what actually makes someone a great herbalist?
Is it wildcrafting in the woods? Brewing up tinctures in your kitchen? Mastering Latin names on sight?
All solid skills.
But they’re not the thing.
The real difference-maker?
A deep, strategic relationship with materia medica.
Not casual reading. Not skimming for “what it’s good for.”
We’re talking focused study. Repeated encounters. Patterns noticed over time.
Because the best herbalists don’t just memorize lists of symptoms.
They understand the inner blueprint of a plant — how its actions, affinities, and energetics interlock into something greater.
It’s not about more plants.
It’s about knowing the ones you do study — intimately.
So how do you actually get past surface-level herbalism?
How do you study a plant in a way that reveals its core — not just its chemistry or symptom list?
And more than that —
How do you build real competence and confidence, so you’re not just making herbal products…
but fostering wellness with intention and precision?
There’s a method to it.
And once you learn it, everything shifts.

“I’ve gained more practical knowledge from The Green Files than from half the herbal books in my collection. It’s a truly effective and well-structured learning experience.”
No doubt about it — this is the best herbal resource I’ve come across. Roland’s knowledge is on another level, and I’ve never learned this much from anyone else. Honestly, the price for The Green Files seems too good for the value you get. I’ll be learning from it for years.

The Road to Herbal Mastery
This isn’t just another herbal course. It’s a system — built to train how you think, not just what you know.
Beginners get a rock-solid foundation.
Advanced herbalists get the missing links they didn’t know they needed.
You’ll go deep into the mechanics of plant medicine:
herbal actions, tastes, energetics, constitutional patterns — the stuff that makes the difference between knowing herbs and working with them.
And with a rich materia medica to back it up, you’re not just collecting facts —
you’re building a practice that actually works.
Core PILLARS. Real Understanding
In The Green Files, you won’t just memorize herbs — you’ll map them.
Each plant is broken down by taste, action, energetics, organ affinity, and specific indications — revealing how its properties weave together into a complete pattern.
You’ll start to see the deeper logic behind why a herb does what it does — and how it moves through the body, structurally and functionally.
Because mastery isn’t about more info. It’s about seeing the connections.
From Plant Patterns to Real-World Practice
In The Green Files, you’ll learn how to match herbs to people — not just problems.
Instead of memorizing symptom lists, you’ll study how a plant’s core actions, energetics, and constitutional tendencies line up with specific physiological patterns.
It’s about understanding why an herb works — and when it truly fits.
So when you reach for a remedy, it’s not guesswork.
It’s precision.
Know the Risks. Work with Confidence
Herbalism isn’t just about what a plant can do — it’s about knowing when not to use it.
In The Green Files, you’ll get clear on safety: contraindications, side effects, drug interactions, and the pharmacology behind each herb.
Because when you understand how a plant works biochemically, you can use it wisely — and keep the people you care for safe.
Get the Medicine Out — The Right Way
Every plant has its own chemistry. And every preparation pulls out something different.
In The Green Files, you’ll learn which methods unlock the most from each herb — teas, tinctures, oils, and beyond.
Right Herb. Right Dose. Right Time
Knowing what to use is just the start — knowing how to use it is what makes it work.
In The Green Files, you’ll get practical, clinical guidance on dosage, delivery methods, and how often to give each herb.
Because precision isn’t optional — it’s what turns theory into real results.
Formulate with Purpose
Knowing a plant is one thing. Knowing how to work with it in a formula? That’s where things get real.
In The Green Files, each herb profile gives you practical examples — from simple pairs to full blends — that show how the herb plays with others.
You’ll see how to highlight its strengths, balance its edges, and use it in formulas that actually make sense.
Old World Wisdom Meets Modern Insight
Every profile in The Green Files pulls from multiple worlds —
Ayurveda, Traditional Chinese Medicine, Western herbalism, and contemporary science.
The result? A 360° view of each plant: physical, energetic, and spiritual.
Because real understanding doesn’t come from one lens —
it comes from seeing how they all connect.
More Than a Profile
In The Green Files, the profile isn’t just a fact sheet — it’s a teaching tool.
Each one is built as a framework to learn the bigger picture: anatomy, physiology, energetics, constitutional theory, pathophysiology, chemistry, tastes, actions — all through the lens of a single plant.
It’s how beginners build a foundation — and how experienced herbalists sharpen their edge.
What’s Really Inside a Profile?
Forget the one-paragraph summaries and bullet-point lists.
The Green Files takes it way further.
These profile are built as full-spectrum learning tools — crafted to teach you the why, how, and when behind each plant’s use.
Each one breaks down core herbal principles while walking you through the anatomy, energetics, chemistry, actions, and clinical applications of a single herb.
We’re talking 20+ pages of knowledge — per plant.
Because understanding an herb deeply means studying it from every angle.
The Five Pillars
Every profile starts with what we call the Five Pillars — the core framework for understanding a plant holistically.
This section breaks down:
- Tastes – What’s the plant’s dominant flavor, and what does that tell us about its function?
- Affinities – Which systems, organs, and tissues does it zero in on?
- Actions – How does it actually work once it gets there?
- Energetics – What shifts does it create in temperature, moisture, tone, and constitution?
- Special Potency– What makes this plant stand out? Think specific indications, emotional impact, spiritual traits.
Never heard of some of these? No problem. Every lesson walks you through the concepts so they click — whether you’re brand new or brushing up.
And this isn’t just a checklist.
It’s a layered, interwoven map — one that shows how these five elements combine to reveal the plant’s true medicinal fingerprint.
Forget the Lists — Learn the Patterns
Most herbal books hand you a list:
“Good for headaches, cramps, colds…” and call it a day.
But The Green Files flips the script.
Instead of memorizing symptoms, you’ll study the core clinical patterns the plant addresses in the body.
Yes, you’ll still see which conditions the herb is used for —
but more importantly, you’ll learn why it works… and for whom.
You’ll start recognizing the specific types of people and physiological imbalances a plant truly supports — giving you sharper precision when choosing remedies.
It’s a whole new lens.
One that teaches you to think with the plant — and treat the person, not just the problem.
Section Three: From Insight to Application
This is where it all comes together — the how behind using the plant effectively.
You’ll explore:
- Pharmacognosy & Chemical Actions – what’s happening at the molecular level
- Safety & Contraindications – when to pause, and what to avoid
- Harvesting & Preparations – how to work with the plant from field to bottle
- Formulation Strategies – blending with purpose, not guesswork
The goal?
A full-spectrum understanding — chemical, energetic, and practical — so you can use each plant with clarity, confidence, and care.
Built for Beginners. Trusted by Pros.
Just starting out? No worries.
We break down every core concept, term, and principle — so nothing flies over your head.
Plus, you’ll get bonus materials to build a rock-solid foundation in holistic herbalism.

Meet Your Instructor: Roland Koronya
Biologist. Herbalist. Founder of The Green Guild
Hey — I’m Roland.
I’ll be your guide here at The Green Files. And if you’re wondering who I am or why you should trust me with your plant path — fair question.
I’ve got a degree in Biology (Herbal Sciences, University of Pécs, 2012), which gave me the scientific backbone of this work. But honestly? That’s just the beginning.
What shaped me more was studying under clinical herbalists, learning directly in practice — and spending the last decade teaching thousands of students across Europe.
My approach? Holistic in the truest sense.
Physical. Energetic. Spiritual.
Because healing isn’t just about removing symptoms — it’s about helping people feel alive, inspired, and connected to their deeper purpose.
That’s what the plants gave me. And it’s what I hope to pass on to you.
