Get the skills you need to become a practicing clinical herbalist.

In this course, you’ll learn how to support more complicated health situations, dig deep into herb-drug interactions, gain confidence reading scientific studies, and build your practical clinical skills.

At the end of this program, you'll be confident in your capabilities to help others - and you'll be ready to start seeing clients on your own! 

With the right skills, you can change lives.

There is so much we can do to help people move out of discomfort and into vibrant health. As a clinical herbalist, you might collaborate with a team of doctors to support someone in chemotherapy. You might help someone with low functioning thyroid boost their endocrine function naturally. You could teach someone with a chronic illness non-invasive tools to build strength and resilience.

As a clinical herbalist, the work you get to do every day is to make people's lives better.

Confidence to start my practice

Steph Z.

Katja and Ryn have been very influential teachers for me as I navigate my herbal path. I credit them for giving me the confidence and strong foundation I needed to start my herbal practice, and for pushing me to grow in ways I wouldn’t have expected. They are teachers who are deeply devoted to their students, their clients, and to the plants themselves. I am very grateful for all I’ve learned from Katja and Ryn and often refer back to the invaluable lessons and resources I gained from studying with them.

A whole new toolset

Kenton C.

Katja & Ryn really changed my approach to clinical herbalism by giving me many more tools to work with people. They go beyond 'this-herb-for-that' herbalism and teach foundational support of lifestyle, movement, nutrition and sleep - backed by current research and clinical experience - to bring herbalists to a deeply holistic way of seeing the body's interplay of physiology, and the many interventions we can make to direct it toward health.

Help others live a healthier life

As a clinical herbalist, you're making the world a better place, one healthy person at a time!

That's what I want to do!


The pre-requisite for this course is our Family Herbalist program and our Community Herbalist program. Together, that's 250 instructor hours, in addition to self-study and homework.  

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


  • If you have completed a program that is similar to the Family Herbalist and Community Herbalist, with a similar number of instructor hours (in addition to self-study), you will likely feel comfortable in the Clinical Herbalist program.

  • If you have already started seeing clients and would like to deepen your practice, this program may be a good fit.

  • If you feel solid about pathology and physiology, and you're ready to get into advanced topics in holistic health and clinical skills, 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 would like to enroll in the Clinical Herbalist program and you have NOT completed the Family Herbalist program and the Community Herbalist program, please send us an email and ask for the transfer exam. This is the same exam that we give our own students at the end of the Community Herbalist program - if you do well on the exam, you're all set to join Clinical Herbalist!

If there are sections of the exam that are difficult, but others that you have down, you can just choose the courses you need to fill in your gaps before starting the Clinical Herbalist program. And if the exam covers mostly material that you're not yet familiar with, you'll be better off starting with one of the pre-requisite programs.

We are happy to guide you through this process: we want to make sure that you have all the information that you need to succeed!

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."

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 clinical 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. Through the years, that desire grew into a passion to improve her own health and ultimately, to help others to do the same.

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 also members of the review board of the Medical Herbalism journal, and the creators of the weekly Holistic Herbalism Podcast. You can find their first book, Herbal Medicine for Beginners, on Amazon and in local book stores.


  • 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 58 hours+ of video and the accompanying quizzes, notes, and resources.

    This program typically takes 13 weeks 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, we promise: it’s just a start. For comparison’s sake, our first-year “apprenticeship” style program comprises 200 contact hours, spread out over the 9 months it meets.

    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!

  • What are the prerequisites for this program?

    The pre-requisites for the Clinical Herbalist program are the Family Herbalist and Community Herbalist programs, or the equivalent at another school. For students who wish to come in from another school, we have a transfer test. If you'd like to request it, just contact us!
