I can make a difference

One of the big things that initially pulled me to herbalism was the opportunity to embrace a powerful medium for activism. Herbalism has given me a tangible way to help people, and this course has given me the skills to do it well. I'm so glad I did this!

The best herb school online!

Vanessa P.

"I researched different online herbalism courses for about two months and am so glad I found you two. There is so much more than just the material to this course. Because you teach everything in videos, and then with the live Q&A sessions every week, I feel like this is more of an in-person experience than an online course and I love that."

Science and Art

Plants are living beings, and just like us, they’re made of chemistry and magic. 

To understand the human body, and how to care for it, and to understand how to work with plants, we need a little bit of both. 

This program is built on our deep appreciation for the intricate interconnectivity of all beings, and for our place in this world. It’s built on rigorous research and study, from traditional practices to cutting edge research. 

Herbalism isn’t about magical thinking. It’s not about wishing or believing. And good health isn't just about things we can see in microscopes. Every day, scientists are discovering new information about how plants interact with each other and with us, about how our health is affected by the natural world. Much of this work validates what we as herbalists already know - and when we join forces, the work we do can be revolutionary.

This program draws on multiple sources of information & inspiration, which allows us to balance the science and the art, the chemistry and the magic that runs through us all.

That means you get a more complete education, focused on finding the best way to help every person individually - including yourself! You can feel confident whether you’re working solely with holistic approaches or collaborating with conventional practitioners.


The pre-requisite for this course is our Family Herbalist program, though if you like, the two programs can be taken concurrently


If you have already studied herbalism on your own or through another school, here are some guidelines to help you decide whether this is the right course for you:


  • If you know between 70-100 individual plants and feel comfortable working with them, you will be comfortable in this program.

  • If you are able to make various different types of herbal medicines, you’ll be comfortable in this program.

  • If you have started learning about pathology and physiology, and are ready to go deeper, or if you haven’t started that step in your learning yet but you’re ready to, you’ll be right at home in this program.

If you’re not sure where the best starting point would be for you, just ask! We're happy to help guide you.

If you are interested in taking both the Family Herbalist and the Community Herbalist at the same time, you can bundle them both into one payment or payment plan here.

You helped me make my dream job!

Mikayla B.

I am so grateful I took this program. I now run an herb shop in the center of my town and it's literally a dream come true. I feel like I finally have my home and my people. My herbal knowledge has sprouted into some awesome things, you guys teach it so right!

Zero-Risk Return Policy

Teaching isn't just about conveying information - there's also an aspect of being someone's "cup of tea".

So we want you to take the first 14 days to really decide if you love it or not. If for any reason you feel like this program isn’t right for you - if we're just not your cup of tea - we’ll give you a full refund. You don't even need a reason - just please let us know within 14 days of purchase.

Be part of our community

Join a like-minded community of herbalists who want to make this world a better place, more in tune with nature. 

We teach every class personally, and we're teaching from our own experience – not just in our clinic, but even in our own bodies. We prefer the video format because it's much closer to actually being in the classroom. Between the videos, the weekly live Q&A webinars, and our direct answers to all of your questions in the discussion thread, we'll get to know each other--you’ll never feel isolated or anonymous.

And it’s not just us - you’ll get to know the students you’re working with too: we love to see students chatting in the Q&A sessions, sharing ideas and even swapping plants and seeds. Join our group of plant lovers healing ourselves, our communities, and the earth!

In love with this community!

Peggy L.

"I really, truly, madly love you guys and the community you have built with the plants and with us students. Not only that, this all comes at a perfect time: it’s been pulling me up through some darkness and it has been a lifesaver. I love having something positive to focus on and I feel like the more I get herbs into my life, the more the awfulness I’ve been dealing with in my life is falling away. I love learning with you."

Your Teachers

Two heads are better than one!

Katja & Ryn
Katja & Ryn

Katja & Ryn almost always teach together. They each have particular talents and areas of interest, and their perspectives on certain issues are quite different! Together, they convey a fuller picture of the realities of herbal theory & practice than either one could do alone.

Katja is an herbalist and teacher working to help people rebuild their relationships with their bodies and their own ability to heal. She’s been in practice for nearly 20 years, but it all began with a desire to make her own “fancy tea” at home instead of paying high prices for imported blends at specialty stores. She’s kept that do-it-yourself ethic close to her heart.

Ryn has been a practicing herbalist since 2010. He came to herbalism by way of martial arts, where his first experiences with herbs were focused on getting back into the game and becoming more flexible, adaptable, and resilient. Passing that experience on to others is what keeps him motivated every day.

Together, Katja and Ryn teach everyone from children to elders, as well as pharmacy students from Massachusetts College of Pharmacy and Northeastern University School of Pharmacy, where they both serve as associate faculty. Ryn and Katja are the authors of Herbal Medicine for Beginners, and the creators of the weekly Holistic Herbalism Podcast.

In-person Intensives

Both in-person in Boston and in-person by web-conference

Would you like to add an in-person component to your program? We've got that! Throughout the year, we have workshops and intensives scheduled on various topics to help you deepen your learning experience! 

You can find all of our live events here:


They're a great opportunity to work with us directly, whether here in Boston, in the forest in Royalston, MA, or live online in small-group web conferences on specific topics.  

Plus, you can join in the Live Community Mentorship


  • Can I really learn herbalism online - isn’t this the kind of thing that needs to be really hands-on to be understood?

    It’s absolutely true that you can’t deeply understand and the practice of herbalism just by reading, watching, or listening alone - you do need to get your hands dirty to learn this. However, you also can’t learn herbalism simply by being in the presence of a teacher. The real question is, do you get direct contact with the plants? It’s that contact, along with some guidance and structure, that makes the difference. And we’ll help you make that contact, even from a distance - we’ve got a system for it, and it works!

    This is material we’ve developed over our combined years as practitioners and teachers - that’s 20 years for Katja and 11 for Ryn, and counting! - and we’ve thought long and hard about how to best present it at a distance while maintaining the authenticity of presence. What we offer here is the result of continual, ongoing refinement in methods of conveying that material to you, so you can really come into your own as an herbalist.

  • This seems like a lot of material. How long does it take to complete?

    You have access to the whole program starting the moment you sign up, and you can take as long as you need to work through all 200 hours+ of video and the accompanying quizzes, notes, and resources.

    This program typically takes about a year for students to complete, but you can watch the videos at your own pace, and re-watch them at any time. That is, indeed, a substantial time commitment! When it comes to herbalism, though, time is knowledge.

    Each lesson is structured so that you can have time to actually do the work of experiencing, experimenting with, and exploring different ways of interacting with the herbs.

  • Will I be a “certified herbalist”, “licensed herbalist”, or “master herbalist” after completing this program?

    This is actually a complex question to answer - and the long answer gets into the oddities of professional regulation, educational standards, and related topics - but the short version goes like this:

    Herbalists in the US are not certified or licensed by any governmental body, which means that neither we nor anyone else can make you a “certified herbalist” - just an herbalist with a certificate. Similarly, herbal schools in the US are not accredited according to any national standard, and terms like “master herbalist” or “certified herbalist” are used by different people to indicate very different courses of training and experience. Many schools do use that terminology, because it’s something that our culture sees as recognition, but these are not titles with a uniform meaning or any legal status.

    Given all of the above, when choosing an herbalist to study or consult with, you have to keep your critical thinking hat on and assess each school, teacher, or practitioner on their own merits!

    At our school, we look at mastery of herbalism as a lifelong, ongoing pursuit - not something earned after a single year of study. We teach skills and practices that will make you a competent, safe, and confident herbalist - now and in the future.

    We are a Member School of the American Herbalists Guild, and all of our programs do complete with a certificate documenting your hours of study, which can be helpful if you choose to join the AHG as a professional member in the future. If you’re interested in recognition by the American Herbalists Guild, we can help! The following course progression meets the educational requirements to qualify as a professional member:
    Family Herbalist
    Community Herbalist
    Clinical Herbalist
    Clinical Mentorship

    During clinical mentorship, you have the potential to meet the clinical requirements for professional membership as well. We’re happy to help guide you through that process!

This was such a terrific introduction to energetics: at the level of the individual, organ/tissue state, as well as the herbs and their actions. It also included a brief intro to several other different traditions (such as Chinese, Ayurveda, Native American, etc.), that allowed me to get a glimpse of how having a schema for understanding energetics and a person's constitution has been used from a number of different perspectives (across time and place) to guide healing. I will definitely be following up with some of the book recommendations!

I have taken herbalism classes that briefly went over formulating, but I never felt like I was really understanding it that well. Katja and Ryn do such a great job explaining it in a way that is easy to understand. The examples that they go over really helped me to get a better understanding of which herbs to choose and why. I feel much more confident when formulating now.
