Certificate Information
You will receive a certificate for the successful completion of this course.
This course has 167 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.
Two Tuition Options!
We want to make this course as accessible as possible, so there are two ways to enroll.
If you prefer a monthly payment plan, we made it super easy - just $20/month!
You'll get all the videos, activities, printables, and more for a new herb every week for 23 months!
This is great if you're on a budget, or if you prefer to focus on one thing at a time. Each week a new herb will unlock, like an adventure, so that you always have something new to work on!
we offer payment plans to make our courses more accessible. a payment plan carries a commitment to complete all of the payments.
If you prefer a one-time tuition payment, you can do that for $400, which saves you $60!
You can access all of the content in this course immediately.
This is great if you know that you like to skip around in the material, so that you can find what you need in the order you need it.
$400 one-time payment - save $60!
Either way, your access never expires, and you get free updates for life!

Read MoreI am no spring chicken :) As such, deciding to study herbalism at a later stage in my life was something that, although I knew was the path for me, I was highly skeptical of. I looked through so many schools and various courses and each one sounded great! Then I came across Ryn and Katja. As soon as I watched the first introduction video, something clicked. I saved up and bought this first module, the Materia Medica. I have loved every minute of every video. I am so pleased with the way they both teach and I simply cannot sing enough praises for the two of them. Their vast knowledge and true passion for what they do is evident in this course. I cannot wait to venture further in my own studies.

Read MoreI learned so much in this module. I'm so glad I decided to take it as a part of the herbalism 101 bundle. Katja and Ryn make learning extremely accessible and I appreciate how sensitive they are to environmental, social and economic injustices when talking about herbalism. I'm looking forward to the medicine making portion of the bundle and feel like this gave me a really good foundation. I highly recommend it!

Ryn and Katja made the content enjoyable and easy to understand and really fueled a desire and got me stoked to know and understand the plants more. I am looking forward to taking the Community Herbalist Program soon. Grace Bisaro

Read MoreI joined this class after listening to the free podcast for a few months. Katja and Ryn's approach to Herbalism is fun, practical, and unique. As an individual who has trouble with traditional approaches to learning, the Materia Medica class was refreshing, easy to follow and challenging at the same time. What I learned here helps with my aromatherapy classes and vice versa.

Read MoreI absolutely adored this course. The combination of video, audio file, text and short quiz for each herb is such a brilliant idea and for me was just the perfect match for my learning style.

I love learning with them so much and will keep learning with them until I run out of courses to take ;)

Read MoreI finished Materia Medica, yay! When you first look at the list of herbs covered, it can be overwhelming. And, when you've gotten through the first few, you still might feel like there is NO way you will be able to retain (or understand) any of this information. But, somewhere along in the process, you start to GET IT. You might really notice this when taking a quiz - you read a question and think, 'hey - I don't remember them specifically covering this in the video(!?!)' But then...magic happens (or critical thinking, but it feels like magic) and you start to put the pieces together on your own, 'well if this herb has astringent properties than the correct answer to this question would be..." Magic! Honestly, the teaching style, the presentation, the explanation of how the herbs work in our bodies (and just how our bodies work in general), and their truly congenial personalities, make Katja and Ryn the herbal dynamic duo! You should really take this course.

Read MoreThe Materia Medica course really changed how I was learning about herbs. By the end of the course, I was seeing so many connections between the herbs and how to use them. I absolutely loved this course --the instruction was top notch. I rarely had questions because each module was so thorough. Katja and Ryn are so generous with their knowledge and I have enjoyed all aspects of their teaching . I've already signed up for two more courses and I can't wait to start my next course !
Read LessYour Teachers
Two heads are better than one!
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 25 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.
