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

In this program, 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.

This program has pre-requisites. More information below!

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!


The pre-requisite for this course is our Family Herbalist program and our Community Herbalist program. Together, that's more than 400 instructor hours, in addition to self-study and homework.  

When you have completed those two programs, you'll take the exam at the end and schedule a session to go over your exam with Ryn and Katja. Then you'll be invited to enroll in the Clinical Herbalist program!

If you have already studied herbalism 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 (that means time where a teacher is actually teaching in person or by video, and does not include self-study, reading time, homework, experiments, etc. if you attended an herbschool that includes homework in the program hours, you should only count the actual number of hours you spent directly with an instructor.), 
  • a specific focus on clinical perspectives in the work
  • a vitalist paradigm - ie, the program places equal priority on holistic interventions such as sleep, food, movement, and stress as well as herbs
  • a deep understanding of herbal energetics and actions, tissue states, and constitutions and the ability to formulate specific to a person's constitution
  • a thorough understanding of working with food allergies, sensitivities, and intolerances and how they apply to various pathologies
  • a core understanding of anatomy and physiology

...then we invite you to ask for the transfer exam!


If you have taken self study programs such as Sage Mountain, Herbal Academy, Chestnut, or Centre of Excellence, then you might feel comfortable skipping the Family Herbalist program and starting with the Community Herbalist program, but you won't be ready to move directly to Clinical Herbalist.

These programs give you a great introduction to herbalism and help you to decide whether this is something you want to pursue more deeply, and although they will not have prepared you to pass the transfer exam, they are a vital part of your journey in herbalism and getting you to this point!

If you have taken one of these programs, or if you have learned herbalism through self study, you will be best served to start your clinical education in the Community Herbalist program

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 click here for more information and to request a transfer exam.

This program includes:

300+ hours of video instruction across 20 individual topics - plus references, resources, and more! In each course, in addition to your thorough understanding of the topic, we prioritize your ability to teach your clients what they need to know so that they are empowered as active participants in their own health.

  • Advanced Energetics - Dig deeper into the energetics of traditional western herbalism, as well as understanding how to collaborate with practitioners from other traditional systems. Learn how to apply energetics in your clinical consultations, and how to teach clients what they need to know to understand the herbal protocols you create.

  • Clinical Nutrition - Build nutritional goals that support your herbal protocols, and learn how to teach your clients how to carry them out. Build strategies to motivate your clients and to overcome roadblocks to better nutrition.

  • Sleep Pathologies - Sleep is a critical part of good health: learn how to overcome clients' issues with sleep. Build protocols and strategies to resolve the issues that lead to insomnia, frequent waking, sleep latency, and more.

  • Stress and PTSD - Stress impacts health at a foundational level. Learn how to help clients reduce stress even in complicated situations. This course also includes mental health support and PTSD support strategies, as well as how to support your clients through the physiological effects of stress, such as hypercortisolemia, etc.

  • Detox - "Detox" is a complicated topic, and many clients are looking for help in understanding the issues. Help your clients understand how the body's own process of detoxification works, how they can support that, and what they should do if they are interested in a detox program.

  • Holistic Approaches to Chronic Illness - Chronic illness and chronic inflammatory diseases are the most common issue we see in our practice. Understand the pathophysiology behind these issues and learn to create protocols to help your clients manage them successfully.

  • Insulin Resistance & Diabetes - Holistic strategies can make an enormous impact for those who are insulin resistant or have diabetes. Learn how to support your clients safely, how to educate them about how they can strengthen their metabolic health, and how to collaborate with their medical practitioners so that every member of the client's care team - including the client! - is working together towards better health.

  • Autoimmunity - Autoimmune issues are complicated, but they respond very well to holistic intervention. Learn how to understand the myriad of autoimmune issues and how to build integrated protocols to help your clients build strength, resilience, and a more vibrant life.

  • Endocrine & Hormonal Health - Learn how to support health issues that stem from the endocrine system - such as thyroid disorders, adrenal depletion, reproductive issues, chronic fatigue, and more. Gain insight into how intricately the endocrine system is intertwined with overall health and how it plays a role in all health issues.

  • Cancer Support - Cancer care is evolving rapidly: learn how to integrate herbal and holistic strategies safely to support your client's health goals and get the best outcome from the interventions they choose. Learn how to collaborate with your client's oncological team so that everyone is working together to support your client's goals.

  • Managing Lyme - Learn how to build effective strategies to support your clients' recovery from Lyme, and help them to understand how Lyme and its coinfections can be managed to prevent relapse.

  • Issues around Birth Control - Birth control choices are complicated and personal.

  • Prenatal and Post-partum Support - Learn how to safely work with herbs in pregnancy and during lactation, how herbs can support complications in pregnancy and post-partum recovery, how to prevent post-partum depression (or to support it if it's already happening), and how to collaborate with your clients' birth practitioners.

  • Holistic Health for Elders - Because our elders are frequently taking multiple pharmaceuticals, supporting their health issues can become complicated. Learn how to support vibrant longevity, how to deal with health issues in older populations, and how to build protocols to help our elders be as strong and resilient as possible. This course also includes strategies for supporting those who care for elders, including the adult children of elders, who often face special challenges as they balance caring for their families and their aging parents.

  • Seeing Clients - Learn how to structure a consultation, how to practice within the law, and how to motivate and empower your clients.

  • Assessment Skills - Build your ability to see the whole, interconnected picture using a variety of techniques. Although we depend primarily on discussion as a method of understanding a client's situation, there are many other observational skills to develop to help you gain a more complete picture of the ways you can best support your clients.

  • Intake Analysis - Learn how to design your intake form and how to understand the story that your client tells you through it. Become adept at seeing connections and learn how to use the information they share to determine the best methods to support their goals.

  • Clinical Observation & Experience - Students participate as practitioners in our monthly Free Clinics as well as in the longer consultation format monthly Student Clinic Sessions. These are done by live video conference and there is a dedicated case review and Q&A session after each monthly clinic event.

  • Herb-Drug Interactions - Because most doctors and pharmacists don't know very much about herbs, the primary work of ensuring that herbal protocols won't cause problems with a client's prescription medications falls on the herbalist. This is a rapidly-developing field, and this course covers not only the information we know to date, but also how to stay current on all herb-drug interaction issues, and how to logic through potentional interactions in situations without documented data.

  • Advanced Formulation - Learn to build herbal formulas that are more complex and targeted to the types of problems covered in the Clinical Program. Create formulas that work across multiple systems, and work creatively to consolidate your work across multiple factors.

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 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.


  • 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, check your pre-requisites by clicking any of the green buttons on this page, and then let us know!

  • 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!

  • How can I become a Registered Herbalist in the American Herbalists' Guild?

    Our program will get you there! Once you have completed the Family Herbalist, Community Herbalist, and Clinical Herbalist programs, you will have met and exceeded your educational requirements.

    You'll then be ready to move into your Clinical Mentorship, which takes place live by video conference in small groups, so that you not only learn from your own case reviews, but from others as well. Plus, you'll be building a network of peers who you trust to support you as you transition into your new profession!

  • 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.

  • How will I do clinical observation hours online?

    It's no problem! We include online clinical observation and practice time for all students - even those who are local to us - because these days, so many people want to do online consultations even if they are local. Consultations online allow people to meet with you even if they don't have child care, or if they can't take time off of work, etc. So we want everyone to be trained to work online as well as in-person.
