Digestive upsets are often at the root of more serious problems.

Whether it's "just gas", or something chronic like Crohn's, learn how to resolve gut issues and build your whole body healthy!

You've heard the sayings:

An apple a day keeps the doctor away

That one started in the early 1900s, and although they didn't know it at the time, it turns out that can apples play a huge role in the health of our microbiome - they were on to something!

You are what you eat

This one comes from a medical writer in France in 1826 - and he wrote it in a publication about sugar and white flour being the cause of a growing epidemic of inflammatory diseases in France at the time!

All disease begins in the gut

That comes from Hippocrates - in 300 BCE! And medical research is finally starting to catch up as we find significant correlations between chronic inflammation and gut health, mental health and gut health, immune function and gut health, endocrine function and energy levels and gut health - even cardiovascular and nervous system function and gut health!


People have been looking at supporting gut health to support whole-body health for literally millenia - and often for the very same diseases and discomforts we are dealing with today.

In this course, you'll learn how to:

  • resolve temporary digestive discomfort with herbs
  • manage and heal from chronic digestive illness
  • build strong healthy gut function
  • support the whole rest of your body through your digestive health
  • the best herbs and formulas to support all kinds of gut troubles


This course includes 16+ hours of video instruction, as well as PDF handouts, resesarch resources, quizzes, and more - plus weekly live Q&A discussions where you can talk directly with Ryn and Katja.


It's hard to trust your gut feelings when you're mostly feeling pain. If digestive issues are cramping your style, discover the many ways herbs can help!

I want to learn now!

  • Build your whole health

No signs of Crohn's!

Kathryn Z.

Last week I had to get my regular colonoscopy checkup for Crohn's and for the first time it came back clear - no signs of Crohn's! I've been working with the material in this course for the past several months and I can't believe the difference it's made for me!

Certificate Information

You will receive a certificate for the successful completion of this course. 

This course has 48 credit hours.

This represents the actual time of video instruction and live Q&A, as well as the time allocated for your capstone assignment, quizzes, and other assignments & activities required for completion of the course.


It is reasonable to plan about twice that much time to complete the work: this is because most students like to watch the videos more than once, review their notes, and many students complete more than the required activities. You might also enjoy joining a study group in our Student Community, and you might choose to work on extra activities together as a group to help you internalize all that you've learned. 


Regardless of how long it takes you, there is never any pressure! You have access to this material for life, and in fact, when we add updates and new materials, you receive it all for free, automatically!


If new material is added after you have received your certificate, we are happy to send you a new updated certificate to document the additional time when you complete the new material.

Scholarships & Discounts

You can find complete information about our scholarships and discounts here.

16+ hours of in-depth videos, downloadable quick guides, live Q&A sessions, and more - all for $200!

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.

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.
